FINANCIAL IMPACT: "There is no negative impact on the General Fund. The Airport Enterprise Fund will receive lease and other revenues and the County General Fund will receive property,sales and possessory interest tax revenues from this development. Upon completion of construction rent period (at$2,000 per month),the ground rent will begin at$21,000 per month(or$252,000 per year and increase annually by the CPT inflator. Every 10 years the lease will be revalued based on market appraisals. III. REASONS FOR RECOMMENDATION/BACKGROUND: The project is needed in order to accomodate demand at the Airport for additional general aviation aircraft facilities and services. The site is about 10.3 acres of County owned land at the Buchanan Field Airport, located entirely within the unincorporated County on the east side of Marsh Drive and south of Sally Ride Drive and the County Airport offices as shown on the attached property map. The parcel is adjacent to the Buchanan Field runways and is designated for aviation use on the Buchanan Field Master Plan. The project consists of approximately 44 infill aircraft hangars of various sizes, some with small attached office spaces and a pilot's lounge. A maximum of 142,400 square feet of hangar space and 30,000 square feet of auxiliary office,limited vehicle garage and storage space may be constructed on this site.The project also includes an apron, parking lot and landscaping. The project will be constructed as individual for sale hangar units (hangars) for aircraft hangars and the developer's interest as lessee under the lease will be assigned to a hangar owners' association once 90%of the hangars have been sold to third party hangar purchasers. The hangar owners will hold title to their hangar and a sublease of their hangar and common area from the hangar owners' association. Upon expiration of the lease or earlier termination thereof, title to the hangar improvements will vest with the County. The leasehold held by the hangar owners' association will be subject to a recorded set of covenants. conditions and restrictions. The project site was predominantly vacant land. However, the Concord Flying Club, Mount Diablo Pilots Association,four(4)large aircraft hangars and tie-down tenants were located on the northern portion of the proposed development site. On November 8,2007,the County sent Notices to"Terminate to these tenants as required by their existing forms of agreement.Airport staff subsequently worked with those tenants to find them other locations on Buchanan Field Airport. On December 18,2007,the Board adopted a Mitigated Negative Declaration and the Mitigation Monitoring Program in compliance with the California Environmental Quality Act for the Buchanan hangars LLC Buchanan Field Development Project. Further,on December 18,2007,the Board approved the Director of Airports to enter into a lease with Buchanan Hangars LLC for a term of forty years for the purpose of constructing and operating executive hangars, some with adjoining office area, at Buchanan Field Airport. On March 11,2008,the Board approved a First Amendment to the Lease with Buchanan Hangars LLC.The .First Amendment to the Lease was provided to allow Tenant the time necessary to complete the phase two environmental process and determine the steps that were needed to be taken for, and associated costs of, complying with the CEQA mitigation requirements,the phase two environmental site assessment findings, and wetlands mitigation and species monitoring on the leased premises. Further,it provided the Tenant with a sixty (60) day period of time, or until May 12, 2008, to terminate the Lease without penalty. SUBJECT: Approval and Authorization to Execute a Lease, Buchanan Field Airport DATE: August 19, 2008 PAGE: 3 On May 12. 2008, the Tenant terminated the lease due to unforeseen difficulties with completing the remaining predevelopment items necessary to bring the project to construction. Airport staff then confirmed the available options for selecting another developer based on the Board's approved Airport Development Selection Process by contacting the 2"d ranked bidder, Airport Partners, and the -) ranked bidder, Silver Pacific, about the project changes and to gauge their interest in the site. In the meantime, on May 28. 2008, the Aviation Development Group (ADG). sponsor of the Buchanan Hangars LLC project,expressed renewed interest in completing their original development plan since much of the groundwork for the development had already been completed. Airport staff restarted lease negotiations with ADG for the Buchanan Hangars LLC project as this proposal continued to be the most financially beneficial,aesthetically pleasing and project ready approach of the available options(Exhibit C& D). Staff recommends that the Board acknowledge the termination of the original lease dated December 18, 2007 and approve and authorize the Director of Airports to execute a new lease and access easement with Buchanan Hangars, LLC, copies of which are attached hereto, and to execute a memorandum of both documents for recording purposes. The terms of the attached Lease,including a 40-year term,are the same as the terms approved by the Board on December 18, 2007, except that all payment and performance obligations will be determined by reference to the newly established Commencement Date for the Lease. In addition,the Tenant requested that the property boundary be amended to allow additional space to meet the federal Clean Water Act requirements, separate buildings E and F so that the water line could be placed between them,and to allow for a payment of$400,000 to the Airport Enterprise Fund in lieu of constructing the pilot's lounge: IV. CONSEQUENCES OF NEGATIVE ACTION: Delay in approving the project will result in a delay of developing vacant and underutilized land at Buchanan Field Airport and will negatively impact general aviation aircraft facilities,services, Airport demand needs and the Airport Enterprise Fund and County General Fund. EXHIBIT C CONTRA COSTA COUNTY Buchanan Field and Byron Airports DATE : June 13,2008 TO: Supervisor Susan Bonilla, District.TV FROM: Keith Freitas, Director of Airports SUBJECT: Buchanan Field Airport Southwest 10 acre Parcel.Development On May 23, 2006, the Board of Supervisors selected Aviation Development Group (ADG), dba Buchanan Hangars,LLC as the Master Developer for the 10 acre site at Buchanan Field Airport and authorized Airport staff to negotiate a long-ternz ground lease. However,the lease was terminated, as allowed,by ADG on May 12;2008. Due to the termination of the lease by ADG,Airport staff approached the 2nd ranked development team,Airport Partners,to determine their interest in developing this site.Airport staff also notified the 3rd ranked team,Silver Pacific,about the proj ect changes and to gauge their current interest in the site. Surprisingly, on May 28'h, ADG sent a letter advising that they would like to rescind their termination letter and execute a new lease. On June 6,2008,the third ranked group(Silver Pacific) responded to the County reporting that they are interested in the development site. On June 12,2008 the second ranked group(Airport Partners)advised that they deemed the project unrealistic and were formally withdrawing their proposal. This memoran.dlun details the economic,timing and policy impacts associated with the three options in moving forward to develop the approximate 10 acre parcel on.the southwest side of Buchanan Field Airport. Option 1: Proceeding with the 3rd ranked development team (Silver Pack)since the 2'6 ranked team(Airport Partners) has declined. Impacts to the Comity for this option are twofold; first the economics are substantially lower(see chart below)and second there will be at least a four month delay to execute a new lease and up to a six month delay to start construction (up to 6 months overall since these could be completed concurrently). This six month delay is predicated on the project concept, uses and environmental impacts are similar to those analyzed for the ADG/Buchanan hangars project. If the project parameters are outside the scope analyzed for the ADG/Buchanan Hangars project,then there would likely be a six to twelve month delay to execute a lease and up to an additional six to twelve month delay to start construction (up to 18 months overall since some of the work can be completed Supervisor Susan Bonilla,District IV June 13, 2008 Page 2 concurrently). The economic implications for the two proposed projects, based on proposals and supplemental information axe: Ranked#1 Ranked#3 ADG/Buchanan Hangars Silver Pacific Year $/Sq.Ft. Annual Rent $/Sq.Ft. Annual Rent 1 0.57 $252,016.38 0.30 $132,640.20 2 0.59 $259,576.87 0.35 $154,746.90 3 0.60 $267,364.18 0.40 $176,853.60 4 0.62 $275,385.10 0.45 $198,960.30 5 0.64 $283,646.66 0.50 $221,067.00 6 0.66 $292,156.06 0.52 $227,699.01 7 0.68 $300,920.74 0.53 $234,529.98 8 0.70 $309,948.36 0.55 $241,565.88 9 0.72 $319,246.81 0.56 $248,812.86 Total Rent Over 9 Years $2,560,261.15 $1,836,875.73 Per the above table, the ADG/Buchanan Hangars project provides, over a nine year period, $723,385.42 more than the third ranked proposal. However, the Airport staff would attempt to negotiate a higher ground rent from the lower bidder in an.effort to shrink this gap. Although all three of the original bidders were deemed viable under the established ranking elements, a seven. member Selection Committee determined the following factors most distinguished the three bidders: ® Project concept(size and mix of aviation hangars) ® Financial return to the Airport ® Project design and associated level of proposed investment ® Schedule and timing for construction of improvements and infrastructure Based on the selection process,the County proceeded to negotiate with ADG/Buchanan Hangars.To date,ADG/Buchanan Hangars has reportedly spent over$600,000 to bring this project to fruition.A majority of those costs relate to the detailed environmental review process, subsequent mitigation actions and project drawings.The environmental process was completed and approved by the Contra Costa County Board of Supervi sors in December 2007 based on the ADG/Buchanan Hangars design concept. As noted earlier, if the 3rd ranked developer is willing to stay within the ADGBuchanan Hangars project parameters, then many of the environmental process components should be applicable(assuming that it does not take too long to complete the new lease process).IIowever,if the project is outside the scope for the ADG/Buchanan Hangars environmental review,then it would be subject to another environmental process and could take up to twelve months to complete. To proceed with the 3rd ranked proposal, Airport staff would expect that the negotiated deal with ADG/Buchanan Hangars would be the starting point for new negotiations. If so, this could cause Supervisor Susan Bonilla,District 1V June 13, 2008 Page 3 strong financial impacts to the other proposal due to expected higher ground rent,vastly improved project aesthetics/building design,inclusion.of a pilot's lounge/dedicated meeting space,building project in one versus multi-phases, and providing a varied mix of hangar sizes to accommodate a broader spectrum of users.It is unclear if the 3',ranked proposer,ultimately,would have the capacity and/or be willing to meet these objectives necessary to bring about the quality of development that compelled the Selection Committee to prioritize the ADCr/Buchanan Hangars proposal. County Counsel advises that there is no legal issue by proceeding with any of the ranked proposers for development of this site. Further, there is no legal obligation to proceed with the P ranked proposal. The adopted selection process provides flexibility for County/Airport staff- to negotiate i�ith those who have been successfully ranked in order to affect the best project and outcome. Option 2: Re-circulate a Request for Proposals Solicitation Airport staff has received 2 new inquiries from development interests to develop this site after ADGBuchanan Hangars terminated their lease.While this could result in some interesting and new project concepts,it would significantly delay project implementation and could ultimately render any project infeasible if economic market conditions continue to weaken. Alternatively, we could undertake a new solicitation process and end up receiving proposals only from those parties we reviewed during the prior solicitation process. This option clearly poses the greatest risk for reduced/loss in revenues and also has the greatest potential to keep any development from proceeding if the economic trends.continue to decline. The solicitation process typically requires up to four months to complete and can be potentially longer if there arc numerous interests or the process is challenged.As discussed in Option 1, if the prgiect concept and scope is comparable to that of the ADG/Buchanan Hangars and the elapsed timing(from approval of the ADG/Buchanan Hangar environmental document)is not too long,up to ten.additional months may be required to negotiate the lease and begin project construction. If the project concept and scope is too different,then it would require ane w environmental analysis(taking from six to twelve months to complete)and may necessitate a change to the Airport Master Plan and County General Plan. Developer ranking determination would be based on the following elements:(1)financial return to the Airport/County; (2)project financial investment and design; (3) financial capacity and track record of project team; (4) project readiness; and (S) schedule and timing for proposed improvements. Re-solicitation for proposals would take from a minimum of six months and up to sixteen months to complete the lease and environmental process and move towards construction. There are no legal or procedural requirements to re-solicit for development of this site.The original solicitation was completed and we ate fortunate to still have two viable proposals to consider now if so desired. Supervisor Susan Bonilla,District 1V June 13, 2008 Page 4 Option 3: Execute a New Lease with ADG/Buchanan Hangars. As mentioned,shortly after terminating their lease,ADG/Buchanan Hangars sent a letter requesting to rescind the termination. Airport staff had already contacted the 2nd and 3`d ranked proposers to determine their development interest. This request does represent the most financially lucrative,aesthetically pleasing and project ready approach of all three options. The ADG/Buchanan Hangars team has continued to keep their environmental and building permit processes engaged, despite the termination, and is closer to having the necessary permits to begin construction. They have reported that they have secured commitments from two construction loan lenders, each. exceeding $14.3 million, providing the capital to begin construction. This is in addition to the almost $5 million in private investment backing already in place. This access to capital is critical since the lending market is currently very risk adverse,especially in specialty markets. County Counsel, again, has confirmed that there is no legal issue with proceeding with ADG/Buchanan Hangars before the 3rd ranked Silver Pacific. In. summary, the following table shows a comparison of time and revenue impacts of the three options: _ Option Estimated Time Delay Estimated Loss in Revenue # 1 —Moving to 3`d ranked* 12 months $63,000 _#2—Re-solicit Project** 16.5 months $129,000 #3—Move back to ADG None None Due to the range potential for both time delay and loss in revenue,the midpoint of each category was used for comparison as it reflects the most realistic expectation.The loss in revenue does not include any potential reduction in ground rent with another proposal. ** Due to the range potential for time delay,the midpoint is used for comparison as it reflects the most realistic expectation.The loss in revenue does not include any potential reduction in ground rent with another proposal. cc: Members—Board of Supervisors John Cullen,CAO Jason Crapo,Senior Deputy County Administrator Beth Lee,Assistant Director of Airports BUCHANAN HANGARSLLC Michael E.Dunn Manager VIA EMAIL Hrei anairport.cccountyx May 28, 2008 Mr. Keith Freitas Director of Airports Contra Costa County Airports 550 Sally Ride Drive Concord, CA 94520-5550 Dear Keith, ADG's recent decision to terminate our lease with the Airport was one of the most difficult we have ever made. I still remain hopeful that we can continue forward with the project. As you may know, even without the lease in place, the water line configuration issue with the Contra Costa County Water District has been favorably resolved. Only two items remain to be resolved--drainage easements from the County and provisions for the construction and conveyance of the Aviators' Lounge to the County or a non-profit organization.. We believe the benefits of moving forward with the project are far greater than not, based in part on the following: I. Economic The economic benefit to the County derived from lease revenue agreed to by Aviation Development Group is significant, especially when compared to the alternate bidders on the project. The annual lease rates proposed by Aviation Development Group (ADG), Airport Partners LLC and Silver Pacific Aviation LLC were $252,000 ($0.57 per square foot), $154,700 ($0.35 psf), and $132,600 ($0.30 pso, respectively. 2939 Ohio Way•Denver, Colorado 80209.303-770-3550.303-777-7823 Fax- michael((D-avia tion de velonmentormy.com Mr. Keith Freitas May 28, 2008 Page 2 of 3 Assuming an annual inflation rate of 3%, projected lease revenue from ADG to the County over a 40-year lease term would be approximately $19.0 million, while Airport Partners and Silver State Aviation would generate approximately $11.6 million and $10.0 million, respectively. Additionally, ADG agreed to construct, at its cost, a 2,200 square foot Aviators' Lounge as part of the project. We expect that the.Airport 'or a non-profit organization will operate this amenity and it will be available to airport tenants as well as the community for conferences, meetings or social events. The current estimated cost for this facility is $450,000. It. Entitlements There are few remaining approvals to be obtained prior to construction commencement. ADG has invested almost$600,000 over the last 2%years to address challenges related to environmental and soils conditions, biological concerns, drainage, wetlands concerns, utilities requirements and FAA constraints specifically related to ADG's designs and its development plans. The California Environmental Protection Act process, Phase 11 Environmental Site Assessment and FAA Form 7460 have been approved,with tree removal and burrowing owl surveys completed. National Environmental Protection Act process and wetland permitting process are nearly complete. Civil engineering plans for grading, drainage and utilities have been completed and submitted for review by Airport staff and the Contra Costa County Building Department. Construction drawings for their review can be completed within the next 45 days. Ill. Financial Capacity ADG has the financial capacity to execute its development plans for Buchanan Field Airport. Four lenders have expressed interest in providing over$14.3 million in construction financing for the project and are close to completing the underwriting process for the transaction. One of the prospective lenders provided construction financing to ADG for its last two hangar development projects in Chino and Palm Springs, California. ADG has secured preliminary commitments from its investors to provide $4.8 million in equity for the project. IV. Team ADG has assembled a highly qualified team comprised of local consultants, engineers and contractors who are collectively responsible for federal, state and local approvals, environmental and code compliance, design and construction: CA1DataI,C=ent ProjectslAviationlDevelopmentlAirportMuchanan\CorrespondancelPreitas.doc Mr. Keith Freitas May 28, 2008 Page 3 of 3 V Timing Construction can commence soon. Completion of construction drawings and final approvals from the County can be achieved within 120 days, at which time construction can commence. Completion carr follow by approximately 14 months. Keith,up until now, we have been through this "war" together and we've succeeded in resolving innumerable challenges. We're too close to getting this project built to quit now. We would liketo rescind termination of the lease, subject to the mutual approval of an amendment to the lease which addresses resolution of the drainage easements and the construction and conveyance of the Aviators' Lounge upon completion to the County or a non-profit organization. 1 look forward to hearing from you soon.

Do.the building heights of the new proposed development by Aviation Development Group violate FAA airspace/safety regulations and/or risk acquiring future aircraft instrument landing systems at Buchanan Field Airport? 2. Will the'ADG project preclude the FAA from installing a WAAS global positioning landing system at Buchanan Field Airport? 3. What was the Process for Selecting a Developer for the Former ADG Site Bidder Selection after ADG terminated their Lease? 1) Proposed Heights of the ADG Hangar Buildings—All development at Buchanan Field Airport is guided by the County's Buchanan Field Airport Policy and Standards for Development, which was adopted in 1979. On page 13, Section (E), Building Standards and Restrictions; "Height Restrictions" states that "the height of all buildings will be governed by the Federal Aviation Administration(FAA) Federal Aviation Regulations (FAR) Part 77". Title 14 of the Code of Federal Regulations (CFR) Part 77 furthers the prime objectives of the FAA to promote air safety and efficient. use of the navigable airspace. To accomplish this mission, aeronautical studies are conducted based on information provided by project proponents on an FAA Form 7460-1, Notice of Proposed Construction or Alteration, to determine the effect of a proposed structure on air navigation.A Part 77 process includes any proposed alteration or construction on or near an airport (within prescribed parameters) which may be impacted by proposed activity. The proposed alteration or construction may be either temporary or permanent in nature. The project sponsor must notify the FAA of proposed activity by submitting an executed FAA Form 7460-1 to the FAA Regional Office having jurisdiction over the area within which the proposed construction or alteration is located. This form must be submitted minimally 30 days in advance of such proposed activity is anticipated to begin or the date for a construction permit is to be filed. Once the FAA has completed the aeronautical study, they will make a determination regarding the impact to air navigation. One of three responses is typically issued: 1. No Objection — The proposed construction did not exceed obstruction standards and marking/lighting is not required; Board of Supervisors Page 2 of 4 2. Conditional Determination — The proposed construction/alteration would be acceptable contingent upon implementing mitigating measures (such as marking and lighting); or 3. Objectionable—The proposed construction/alteration is determined to be a hazard and is thus objectionable. The reasons for this determination are outlined to the project sponsor. Please note that Part 77 is a federally detailed and implemented process that has little or no involvement with local jurisdictions (in this case, Contra Costa County). The FAA receives and communicates directly with the project proponent. Typically, the local jurisdiction receives a copy of the submitted Form 7460-1 and then FAA final determination letter. Please further note that terms like "Protected Airspace" have been used to refer to the area where a building would penetrate the Part 77 airspace. This term is not defined or used by the FAA as it relates to Part 77 surfaces. In November 2007, the ADG submitted their executed FAA form 7460-1 to the FAA. On May 1, 2008, the FAA provided a Final Determination in the form of a conditional determination that stated they did not object to the proposed development providing they implemented identified mitigation measures. Specifically, the FAA required that two of the larger hangar units in Building C be lowered by five (5) feet and that Buildings A, C, D, E, F, G and H include obstruction lighting. Airport staff received the FAA determination and requested that two outside aviation consulting companies provide an independent review to determine if the building heights would impede the County's ability to acquire an instrument landing approach (see WAAS discussion in#2 below)that is currently under consideration by the FAA. The firms of Mead & Hunt, Inc. and Barnard Dunkelberg & Company both reviewed the ADG project under the instrument landing approach criteria. Both firms verified that the proposed ADG hangar building heights would not hinder a future instrument approach. Airport staff also discussed the issue with our State of California-Division of Aeronautics Safety Inspector. He also advised us that he did not foresee any safety or operational concerns related to the proposed project and building heights. Further, Airport staff discussed this issue with the FAA Western Flight Procedures Office staff as they are the ones tasked with evaluating the applicability of an instrument flight procedures approach for Buchanan Field. Rachelle Dailey, Assistant Manager, from the FAA Western Flight Procedures Office'reviewed the information and conveyed that the proposed building heights would not negatively affect the County's ability to acquire an instrument approach. Moreover, due to the complexity of the issues and the often misunderstanding that Part 77 is a primary consideration in making the instrument approach determination, she flew from Seattle to make a presentation to Airport stakeholders regarding the precision approach status for Buchanan Field Airport. During that meeting, she confirmed that Buchanan Field Airport is currently being considered for an instrument approach and that the height of the proposed ADG aircraft hangars would not interfere with that decision. Ms. Dailey further stated that Part 77 surfaces are notassociated with any instrument landing criteria. Rather, Part 77 strictly affects basic visual (clear day)flight rule operations. Consideration for new instrument landing flight procedures are evaluated by the Terminal Instrument Procedures Order(TERPS). TERPS generally takes three primary criteria into consideration; missed approaches, terrain and proximity to another airports' airspace. Board of Supervisors Page 3 of 4 Please note that the County Airport leases also include clauses to protect the future of the Airport should circumstances change which will result in changes to a leasehold property. For example, two standard clauses are"Condemnation and Cancellation by Lessor"which provide the County with the ability to either terminate a lease and/or remove any obstruction, including an aircraft hangar that impedes installation of a future technology that was not contemplated when the lease was created. This lease language provides the ultimate protection for a changing future. In summary, no concerns have been expressed by the FAA, aviation consulting firms, the State of California—Division of Aeronautics or other aviation experts related to the proposed ADG project that the building heights (with identified FAA mitigation measures) would impede the County's ability to 'implement an instrument approach at, or utility of, Buchanan Field Airport. Please note, if the County attempted to override federal jurisdiction regarding Part 77 related issues, it may violate our FAA grant assurances and may lead to legal action and/or a loss of future grant funding. 2) Status of an Instrument Landing Approach. The Wide Area Augmentation System (WAAS) is one navigation service that uses various Global Positioning System (GPS) satellites and geostationary satellites to provide precision aircraft landing capabilities at airports all over the United States. Initial operation of the system began in 2003 and is the system being considered at Buchanan Field Airport The Federal Aviation Administration's Airports District and Flight Procedures Offices direct the process for implementing WAAS approaches to particular airports. The Airports District Office must support a WAAS approach consideration and will then ensure infrastructure requirements are in place and assist with an aeronautical survey of the airport. Once this information is collected, FAA Flight Procedures will begin the process to determine WAAS approach feasibility and limitations, if any. Airport staff has been working with the FAA to upgrade Buchanan Field Airport with an instrument landing system. This process was formally initiated in November of 2001 when an aeronautical survey was completed for Runway 19R, the main instrument landing runway being considered. In 2006, however, due to the close proximity to the San Francisco and Oakland Airports airspace, the typical WAAS Localizer Performance with.Vertical (LPV)approach was deemed infeasible by the FAA Air Traffic Control Branch due to proximity to another airports' airspace. Once an airport is on the list for an instrument approach it is never removed unless requested by the airport sponsor. As such, due to impending changes to the WAAS LPV or LP criteria (publication is anticipated around August 2009), the FAA Flight Procedures Office staff will be reevaluating an instrument approach for Buchanan Field Airport based on the new criteria. Further, based on a 2007 Airport staff request, the FAA will also be initiating an aeronautical survey for Runway 32R, the second primary runway, so that a WAAS LPV,or LP approach could also be considered for that Runway. In summary, the Airport staff continues to work with our federal partner, the FAA, to upgrade the Buchanan Field Airport infrastructure, including the airport landing systems, as funding and technological opportunities become available. . Board of Supervisors Page 4 of 4 3)What was the Process for Selecting a Developer for the Former ADG Site Bidder Selection after ADG terminated their Lease? On May 12, 2008, ADG terminated their lease with Contra Costa County. Airport staff verified with County Counsel that the approved developer selection process allowed the County to select any of the three ranked bidders. Airport staff then contacted the 2nd (Airport Partners) and the 3rd (Silver Pacific) ranked bidders for the approximate 10 acre site at Buchanan Field Airport to determine their current interest in developing the property. Airport Partners, the 2nd ranked bidder, subsequently declined developing the site. Silver Pacific provided written confirmation of their development interest and provided a deposit check, on or about June 10, 2008. Since ADG had also expressed renewed interest in developing the site,Airport staff held the Silver Pacific deposit check until we determined the direction we would take for development negotiations. The County chose to proceed with ADG and Airport staff advised Silver Pacific of that decision on July 22. Silver Pacific asked that the new development deposit be returned with the request that if negotiationsfail to proceed with ADG that they would like the opportunity to be next considered (and would provide a development deposit again at that time). In summary, we are fortunate that we had three viable ranked proposals for this site and that two of the three bidders continue.to have development interest. The decision to work again with ADG was based on the increased financial returns to the Airport Enterprise Fund, project aesthetics, timing considerations and other selection ranking criteria that put them in the top ranked position originally. cc: Members-Board of Supervisors John Cullen, CAO Jason Crapo, Senior Deputy County Administrator Julie Bueren, Public Works Director Beatrice Liu, Deputy County Counsel ADDENDUM August 19, 2008 Agenda Items C.1.3 On this day, Supervisor Bonilla pulled item C.13 from.the Consent Calendar for discussion: ACKNOWLEDGE the May 12, 2008 Notice from Buchanan Hangars LLC, to terminate a 40 year ground lease between the County, as landlord, and BUChanan I-la'ngars LLC, as tenant, for approximately 10.3acres located on the west side of the Buchanan Field Airport. south of the Airport Offices;and APPROVE and AUTHORIZE the Director of Airports, or designee, to execute a 40 year ground lease between the County, as lessor, and Buchanan Ilangars LLC, as tenant, to execute an Access Easement Agreement with Buchanan I-lan( ars, LLC for access to the leased premises in connection with the above lease and to execute a Memorandum of the aforementioned Lease and Access Easement.

In no event shall Ground Rent for any year ever be- less than the Ground Rent in effect for the immediately preceding year. In the event there is a decrease in the Consumer Price Index (CPI), Ground Rent for the year in question shall be the same as,the Ground Rent for the preceding year. I1:\Aiipnrt\Buchanan Hangars,LCCA INAL LEASE 8-12-08.DOC 2 C. Consumer Price Index Rent Adidstment. Effective upon the first day of Years 3 through 9, Years 11 through 19, Years 21 through 29, and Years 31 through 39, Ground Rent shall be increased (or remain unchanged, but not decreased), according to the change in the Consumer Price Index ("CPI") for the most recent one year period ending September 30. The maximum annual percentage increase in.Ground Rent based on a CPI increase shall be six percent (6%) annually. CPI, as used herein, shall mean the Consumer Price Index for all Urban Consumers, All Items, for the San Francisco- Oakland-San Jose Metropolitan Area (1982-84 = 100), as published by the Bureau of Labor Statistics of the U.S. Department of Labor, or its successor. . At no time will the Ground Rent be decreased by a CPI adjustment. In the event there is a decrease in the CPI, the Ground Rent for the year in question shall be the same as the Ground Rent for the preceding year. Lessor will notify Tenant of the increase in Ground Rent when Lessor completes the calculation of the increased rent. If the notice is after the effective date of the increase, Tenant will pay any increased rent retroactively to the effective date. D. Revaluation of Ground Rent. Ground Rent shall be revalued by Lessor on the ninth anniversary of the Effective Date, and thereafter, at the end of each succeeding ten (10) year period of the Lease Term with the revalued Ground Rent becoming effective as of the first day of the following year of the Term. Ground Rent shall be revalued on September 1, 2017, 2027, and 2037 (each, a "Revaluation Date"). Ground Rent shall be revalued based upon the fair market rental value of, the Premises without any improvements, using the Revaluation Process described in this Section 6.D, provided, however, that the revalued Ground Rent shall never be less than the Ground Rent during the preceding year. In, the event there is a decrease in the fair market rental value for the year in question, the revalued Ground Rent shall be the same as the Ground Rent for the preceding year.. Prior to each Revaluation Date, Lessor shall initiate the Ground Rent revaluation process as set forth in detail in Section 6.D(2) below, (the "Revaluation Process") for the determination of Ground Rent for the following period. Ground Rent established through the Revaluation Process shall be reviewed annually for CPI adjustment pursuant to Section 6.C. (1) Conditions of Revaluation. The revaluation of'Ground Rent, including any appraisals prepared as part of the Revaluation Process, shall be conducted under the following conditions: a) All negotiations and actions taken by Lessor and Tenant under this Section shall be undertaken and conducted by the parties in good faith. b) If the Revaluation Process is not concluded by the Revaluation Date, the Ground Rent determined by the Revaluation Process described herein shall be retroactive to the Revaluation Date to which the Revaluation Process applies. Tenant shall make any H:\Airport"Buchanan Hangars,LLCTINAL LEASE 8-12-08.D0C 3 retroactive payments of Ground Rent no later than thirty (30) days following the completion of the Revaluation Process. c) Except as otherwise provided herein, no waiver by Lessor of any of the provisions of this Section shall be.deemed to have been made by Lessor, unless made expressly in writing by the Director of Airports and no waiver by Tenant shall be deemed to have been made unless made expressly in writing by the duly authorized agent of Tenant. d) All time periods specified in this .Section shall be counted in calendar days. (2) Revaluation Process. The Revaluation Process shall consist of the following: a) Lessor shall make an initial determination of the amount of the Ground Rent revaluation (the "Lessor Revaluation") and shall notify Tenant in writing of the amount of.the new monthly Ground Rent (the "Revaluation Notice"). b) If Tenant disagrees with the Lessor Revaluation, Tenant may file with Lessor a dispute of the amount of the Lessor Revaluation ("Tenant Dispute") and include Tenant's proposed Ground Rent revaluation amount. The Tenant Dispute must be in writing and delivered to the Director of Airports no later than twenty-one (21) days after the Revaluation Notice is delivered to Tenant (the "Dispute Period"). In the event that Tenant does not file a Tenant Dispute with Lessor within the Dispute Period, the Lessor Revaluation shall automatically be deemed to be accepted by Tenant, Tenant shall be deemed to have waived the right to contest the amount of the Lessor Revaluation, and the new Ground Rent, as initially determined by Lessor, shall become effective on the applicable Revaluation Date, and the Revaluation Process shall be concluded. c) If Tenant delivers a Tenant Dispute to Lessor within the Dispute Period, Lessor and Tenant shall have twenty-one (21) days following Lessor's receipt of the Tenant Dispute to attempt to establish a new Ground Rent by negotiation (the "Rent Negotiation Period"). . The Rent Negotiation Period may not be extended beyond the initial twenty-one (21) day period except by mutual written agreement of Tenant and the Director of Airports. d) If Lessor and Tenant are unable to agree upon a new Ground Rent during the Rent Negotiation Period, including any agreed upon written extension thereof, then Lessor and Tenant shall proceed to I L\Airport\Buc hanan Hangars,LLC\FfNAL LEASE 8-12-08.DOC 4 the next step in the Revaluation Process by each appointing an appraiser to appraise the fair market value of the Premises and providing written notice to the other identifying that party's appraiser. The appointment of the appraiser shall be made and notice of-the appointment shall be given to the other party not less than twenty-one (21) days after the end of the Rent Negotiation Period (including any agreed-upon extension thereof) (the "Selection Period"). Each appraiser shall be a member of the American Institute of Real Estate Appraisers, have the designation of Member of the Appraisal Institute ("MAI"), and shall have current aviation appraisal experience in appraising property in the geographic real. estate market where the Premises is situated. Each party shall be responsible for paying the fees and costs of the. appraiser it has selected. In the event that Tenant does not appoint an appraiser and provide Lessor with written notice of the appointment within the Selection Period (i) the initial .Lessor Revaluation shall automatically be deemed to be accepted by Tenant, (ii) the new monthly Ground Rent, as initially determined by the Lessor Revaluation, shall become effective on the applicable Revaluation Date, (iii) Tenant shall be deemed to have waived the right to further contest the amount of the Lessor Revaluation by arbitration or in any other manner, and (iv) the Revaluation Process shall be concluded. In the event that Lessor does not appoint an appraiser and provide Tenant with written notice of the appointment within the Selection Period specified in this Section above, (i) the new monthly Ground Rent shall be the Ground Rent as determined by Tenant's appraiser, or as determined in the preceding revaluation of Ground Rent, whichever is greater, (ii) such new monthly Ground Rent shall become effective on the applicable Revaluation Date, (iii) Lessor shall be deemed to have waived the right to contest the amount of the new monthly Ground Rent by arbitration or in any other manner, and (iv) the Revaluation Process shall be concluded. e) If Lessor and Tenant each properly appoint an appraiser during the Selection Period, the issue of the Ground Rent revaluation shall be submitted to the two appraisers to each make an independent determination of the fair market value of the Premises. Each appraisal must be completed and a copy of the appraisal report delivered to the other party no later than sixty (60) days from the date of his or her appointment (the "Appraisal Period") unless otherwise extended by the mutual agreement of Lessor and Tenant. HAAiiport\[3uchanan Hangars,LI_OHNAL LEASE 8-12-08.DOC 5 f) Upon completion of both of the above appraisals, Lessor and Tenant shall make a final attempt to establish a new monthly Ground Rent by negotiation. In the event that Lessor and Tenant cannot agree on a revaluation of the monthly Ground Rent, either Lessor or Tenant may declare an impasse in the negotiations by providing written notice of the impasse to the other party. The written notice of impasse (the "Final Proposal") shall include all of the following information: (i) a statement that the declaring party has determined that negotiations have reached an impasse; (ii) the declaring party's final proposed Ground Rent revaluation figure; (iii) a statement that the recipient has ten (10) days to either give written acceptance of the amount of the Ground Rent revaluation specified in the Final Proposal or deliver a counter-final proposal (the "Counter-Final Proposal") to the declaring party; and (iv) any other supplementary information as the declaring party deems appropriate. The party upon whom the Final Proposal is served shall then have ten (10) business days following receipt of the Final Proposal to either accept the Final Proposal or to reject the Final Proposal and deliver a Counter-Final Proposal to the declaring party. g) If neither the Final Proposal nor the Counter Final Proposal is accepted, not later than forty-five (45) days after delivery of the Final Proposal, the appraiser selected by Lessor and the appraiser selected by Tenant shall jointly select a third appraiser with the designation of MAI and with current aviation appraisal experience and who has substantial experience in appraising property in the geographic real estate market where the Premises is situated. The third appraiser will determine whether the parties will use Lessor's fair market revaluation appraisal or Tenant's fair market revaluation appraisal. The third appraiser shall render a final written decision within thirty (30) days of his appointment. The cost of the third appraiser shall be shared equally by Lessor and Tenant. The appraiser's decision shall be binding on all parties and shall apply retroactively to the Revaluation Date. E. Fuel Flowage Fees. In the event Tenant self-fuels aircraft on the Premises, on the first day of each calendar quarter, Tenant shall pay to Lessor a fuel flowage fee for the preceding quarter equal to $0.08 per gallon (the "Fuel Flowage Fee"). The Fuel Flowage Fee shall increase annually by $0.005 per gallon. The first annual increase shall take place one (1) year from the Ground Rent Effective Date. The Fuel Flowage Fee shall be reviewed and may be revised by Lessor in its sole discretion every five (5) years after the Effective Date of this Lease. Lessor shall give notice to Tenant in writing of any revised Fuel Flowage Fee, which shall be effective the month after such notice is given. H:\Airport\Buchanan Hangars,LLCTINAL LEASE 8-12-08.DOC 6 Tenant may operate a fueling facility or fuel truck on the Premises for the purpose of self-fueling of based aircraft only. ,All self-fueling must be in compliance with Federal Aviation Administration Advisory Circular 150/5190-5. No fueling of automobiles or trucks is allowed on the Premises. Aircraft not owned by Tenant or Tenant's Sublessee may not be taxied to Tenant's fueling facility, and fuel may not be delivered to such aircraft by operation of a fuel truck, or provide any other assistance in the fueling of such aircraft. F. Records to Be Maintained. Tenant shall record all,sales or other transactions, whether cash or credit, and shall keep full and accurate books of account and records in accordance with United States Generally Accepted Accounting Principles consistently applied, including without limitation, a sales journal general ledger, and all bank account statements showing deposits of gross receipts revenue. In addition, Tenant shall keep all cash register receipts with regard to gross receipts, credits, refunds and other pertinent transactions, as well as record of any other exclusions or deductions from gross receipts. 7. ADDITIONAL PAYMENT PROVISIONS A. Late Rental Payments. In addition to Construction Period Rent and Ground Rent, Tenant shall pay as additional rent, all other charges, costs and fees required to be paid by Tenant pursuant to the provisions of this Lease (such amounts, "Additional Rent," and together with Ground. Rent and Construction Period Rent, "Rent"). In the event Tenant fails to pay Lessor Rent due under this Lease within five (5) days after such amount is due, Tenant shall pay to Lessor a late charge of One Hundred and No/100 Dollars ($100) per occurrence (the "Late Charge"), plus interest on said unpaid balance at a rate of one and one-half percent (1-1/2%) per month, from the date said payment was due and payable until paid in full. Tenant shall pay all Late Charges, as Additional Rent on or before the date the next installment of Rent is due. Lessor and Tenant hereby agree that it is and will be impracticable and extremely difficult to ascertain and fix Lessor's actual damage from any late payments and, thus, that Tenant shall pay as liquidated damages to Lessor the Late Charge specified in this Section, which is the result of the parties' reasonable endeavor to estimate fair average compensation therefore (other than attorneys' fees and costs). Lessor's acceptance of the Late Charge as liquidated damages shall not constitute a waiver of Tenant's default with respect to the overdue amount or prevent Lessor from exercising any of the rights and remedies available to Lessor under this Lease. . B. Form and Place of Payment. All Rents and fees shall be paid in cash or by personal check, certified check, or money order, payable to the County of Contra Costa, and must be received on or before due date at the Director of Airports Office, 550 Sally Ride Drive, Concord, California 94520, or at such other place as Lessor may designate from time to time. H:\Airport\Buchanan Hangars,LLCTINAL LEASE 8-12-08.DOC 7 C. Returned Checks. If a check written by Tenant is returned for insufficient funds, Lessor may impose a reasonable service charge in addition to any Late Charge and in addition to any charges imposed by the bank. Lessor may require Tenant to pay Rent by certified check or money order if Tenant's bank or banks have returned one or more personal checks in any twelve (12) month period. D. Security Deposit. Upon execution of this Lease, Tenant shall pay to Lessor the sum. of Forty-Two Thousand and No/100 Dollars ($42,000.00) in cash or by certified check payable to Lessor as security for the faithful performance of the terms, covenants, and conditions of this Lease (the "Security Deposit"). If Tenant is in Default under the terms of this Lease, Lessor may in its sole discretion (but shall not be required to) apply the Security Deposit, or any portion of it, to any expense, loss or (i) any Rent or other sum in default, (ii) any amount that Lessor may spend or become obligator to spend in exercising Lessor's rights under this Lease, or (iii) damage sustained by Lessor resulting from Tenant's Default. Upon demand by Lessor, Tenant shall immediately pay to Lessor a sum equal to the portion of the Security Deposit expended or applied by Lessor as provided in this Section 7.D. so as to maintain the Security Deposit in the sum initially deposited. Upon the expiration or termination of this Lease and a final accounting by Lessor, any remaining Security Deposit balance shall be refunded to Tenant, without interest. Tenant waives the provisions of California.Civil Code Section 1950.7, and all other provisions of law in force or that become in force after the Effective Date of this Lease, that provide that Lessor may claim from a Security Deposit only those sums reasonably necessary to remedy defaults in the payment of Rent, to repair damage caused by Tenant or to clean the Premises. Lessor and Tenant agree that Lessor may, in addition, claim those sums reasonably necessary to compensate Lessor for any other foreseeable or unforeseeable loss or damage caused by the act or omission of Tenant or Tenant's officers, agents, employees, independent contractors or invitees. 8. LESSOR PROCESSING AND TRANSACTION FEES In the event that Tenant requires or requests Lessor's review, investigation, processing, recordation, or any other action in connection with any Tenant document, proposal or other matter (such as review of a proposed assignment or other transfer, an estoppel certificate or financing of Tenant's leasehold interest hereunder), Tenant shall pay such costs and expenses incurred by Lessor thirty (30) days after demand therefore by Lessor.

Safety hazards must be cured immediately. 30. LESSOR'S REMEDIES Lessor shall have the following remedies upon the occurrence of a' Default. These remedies are not exclusive; they are cumulative and in addition to any remedies now or later allowed by law: A. Lessor may terminate this Lease and Tenant's right to possession of the Premises at any time. No act by Lessor other than giving written notice to Tenant shall terminate this Lease. Lessor's acts of maintenance, efforts to re-let the Premises, or the appointment of a receiver on Lessor's initiative to protect Lessor's interest under this Lease shall not constitute a termination of Tenant's right to possession. Upon termination of this Lease, Lessor has the right to recover from Tenant: (1) The worth, at the time of the award, of the unpaid Rent and fees that had been earned at the time of the termination of this Lease; (2) The worth, at the time of the award, of the amount by which the unpaid Rent and fees that would have been earned after the date of termination of this Lease until the time of award exceeds the amount of the loss of Rent and fees that Tenant proves could have been reasonably avoided; (3) The worth, at the time of the award, of the amount by which the unpaid Rent for the balance of the Term after the time of award exceeds the amount of the loss of Rent and .fees that Tenant proves could have been reasonably avoided; and H:1Airporfl3uchanan hangars,LLCTINAL LEASL 8-12-OS.DOC 34 . (4) Any other,amount, and court costs, necessary to compensate Lessor for all detriment proximately caused by Tenant's Default. "The worth, at the time of the award," as used in (1) and (2) of this Section, is to be computed by allowing interest at the rate of ten percent (10%) per annum or the maximum rate permitted by law, whichever is greater. "The worth, at the time of the award," as used in Paragraph 3 of this Section, is to be computed by discounting the amount at the discount rate of the Federal Reserve Bank of San Francisco at the time of the award, plus one percent (1 B.. Lessor, at any time after the occurrence of a Default, can cure the Default at Tenant's cost, provided Lessor has given Tenant thirty (30) days written notice and (i) Tenant has failed to cure such Default within such thirty (30) days or, (ii) if the Default is of such a nature that it cannot be cured within such thirty (30) day period, Tenant fails to pursue such cure diligently to completion. If Lessor at any time, by reason of Tenant's Default, pays any sum to cure the Default or does any act that requires the payment of any sum, the sum paid by Lessor shall be due from Tenant to Lessor within thirty (30) days from the time the sum is paid, upon written notice. given by Lessor to Tenant, and if paid by Tenant at a later date, shall bear interest at the rate of ten percent (10%) per annum or the maximum rate permitted by law, whichever is greater, from the date the sum is paid by Lessor. until Lessor is completely reimbursed by Tenant. Such sum, together with interest accrued thereon shall be paid by Tenant as Additional Rent. In the event of Default by Tenant in connection with the construction of the Hangar Improvements pursuant to Section 12 or the Improvements pursuant to Section 15, Lessor may exercise its rights as an obligee against the surety company on the performance.bond required by Section 12.D. or Section 15.D, as the case may be, and may take such steps as are necessary to cause the cure of such Default by the principal, the surety company, or others. 31. DESTRUCTION Tenant agrees to notify Lessor in writing of any damage to the Premises resulting from fire, earthquake or any other identifiable event of a sudden, unexpected or unusual nature. If any Improvements erected on the Premises are damaged or destroyed as a result of any uninsurable cause or. risk at the time of destruction, in the amount of at least twenty-five percent (25%) of the replacement cost of all Improvements, Tenant shall have the option to either terminate this Leasee or to replace and rebuild the Improvements so they are in substantially the same. condition as they were in immediately before such damage or destruction. Tenant shall give written notice of its election to Lessor within thirty (30) days of the date of the loss or destruction of the Improvements. If Tenant elects to terminate this Lease, this Lease shall terminate. If Tenant elects to rebuild, only Ground Rent will be abated in an amount equal to the amount of Ground Rent due for such month multiplied by the percentage resulting from the replacement costs of damage to the Improvements divided by the replacement cost K\Airport\Buchanan Hangars,LLC\FINAL LEASE 8-12-08DOC J5 of all Improvements for a period not to exceed three (3) months from the date of such written notice, unless otherwise extended by mutual and written agreement by Lessor and Tenant. If the damage is less than twenty-five percent (25%) of the replacement cost of the Improvements, Tenant shall rebuild the Improvements, and no Ground Rent abatement shall apply. Tenant shall have one hundred eighty (180) days to commence repair or restoration of the Improvements, and shall diligently pursue the completion of such Improvements. 32. CONDEMNATION A. If any part of the Premises shall be taken as a result of the exercise of the power of eminent domain or be conveyed to any entity having such power under threat of exercise thereof (both such actions being hereinafter referred to as "Condemnation"), this Lease shall automatically terminate as to the portion of the Premises subject to Condemnation as of the date physical possession of such portion is taken by the condemnor. The value of any damages to the remainder of the Premises sustained by Tenant and Lessor as a result of a Condemnation action shall be determined by a court of law or by negotiation and agreement with'the condemnor. B. If the remaining part of the Premises will not be reasonably suitable for the use described in Section 9, as reasonably determined by Tenant, this Lease may be terminated by either Lessor or Tenant through written notice. to the other party within thirty (30) days of the condemning agency's adoption of a resolution of necessity (or such agency's equivalent determination), to condemn a portion of the Premises. If a Condemnation takes (1) twenty-five percent (25%) or more of the Premises, or (ii) the portion of the Premises providing Tenant access to the Hangar Improvements, Tenant may terminate this Lease by providing Lessor written notice within thirty (30) days of the condemning agency's adoption of a resolution of necessity (or such agency's equivalent determination), to condemn a portion of the Premises. If the remaining part of the Premises will be reasonably suitable for the operation of the business described in Section 9, as reasonably determined by Tenant, this Lease shall continue in full force and effect as to such remaining part. If this Lease is not so terminated, as of the date of such Condemnation, Ground Rent shall be reduced to an amount equal to the product of (i) the then-current Ground Rent multiplied by (ii) a fraction, the numerator of which is the number of square feet of the Premises remaining after such Condemnation, and the denominator of which shall be the number of square feet of the Premises prior to such Condemnation. In the event that all or any part of the Premises shall be taken by Condemnation or conveyed in lieu thereof, both parties shall have the right to pursue a condemnation award against the condemning agency, with Tenant being entitled to any award for lost business, the residual value of its leasehold interest, moving expenses, and the depreciated value of any fixtures or property improvements installed by Tenant, and Lessor being entitled to all other amounts awarded, MWrporOBuchanan Hangars,LLOF NAL LEASE 8-12-0800C 36 including but.not limited to, all amounts awarded for land value. No claim made by or payment to Tenant shall diminish or otherwise adversely affect Lessor's award. Provided that Lessor is not the condemning agency, Tenant shall neither have nor make any claim against Lessor for any loss, damage or other matter arising out of any Condemnation. 33. CANCELLATION BY LESSOR If at any time ten (10) years or more after the Effective Date of this Lease, a governmental agency other than Lessor requires that Lessor use the Premises for purposes other than a non-commercial hangar, Lessor shall have the right to cancel this Lease and to acquire full title, control and possession of the Premises and all .Improvements thereon by giving one (1) year's written notice to Tenant of the effective date of such cancellation. In the event of such cancellation, Lessor and Tenant shall attempt by negotiation to fix the value of Tenant's remaining interest in the Premises and the Improvements thereon, considering the fair market value of the remaining Term of the Lease and the then existing fair market value of the Improvements installed by Tenant on the Premises, and any other factors that might be used in making such a determination. In the event that diligent and good faith negotiations fail to establish an agreement on the amount of compensation to be paid to Tenant, either Lessor or Tenant may give written notice ("Appraisal Notice") to the other, declaring an end to negotiations and requiring the amount of compensation to be paid to Tenant to be determined by the appraisal method set forth in this Section 33. The appraisal method shall be as follows: two qualified and licensed real estate appraisers shall be selected, one by Lessor and one by Tenant. Each appraiser shall be a member of the American Institute of Real Estate Appraisers, have the designation of MAI, and shall have current aviation appraisal experience in appraising property in the geographic real estate market where the Premises is situated. Lessor and Tenant shall each appoint one appraiser within fifteen (15) days of the Appraisal Notice, and the name of the appraiser so appointed shall be given to the other party. In the event that either Lessor or Tenant defaults in the appointment of an appraiser within said fifteen (15) days, the appraiser elected by the non-defaulting party shall name a second appraiser. Upon completion of appointment, each appraiser shall proceed to determine the then existing fair market rental value of Tenant's interest in the Premises within forty-five (45) days of appointment. In determining the then existing fair market value of Tenant's interest in the Premises, the appraisers including any third appraiser appointed pursuant to the following paragraph, shall consider the remaining Term of the Lease and any other factors then currently in use for standard real estate appraisals as fixed by the American Institute of Real Estate Appraisers. Such determination of value shall be binding on both Lessor and Tenant. In the event the appraisers cannot agree upon fair market value within forty-five (45) days of their appointment, they will mutually.appoint a third appraiser, who shall be a member of the American Institute of Real Estate Appraisers, have the designation of MAI and have current aviation appraisal experience in appraising property in the geographic real estate market where the Premises is situated. The third appraiser shall H:\P.irport\Buchanan Hangars,LLOFINAL LEASE 8-12-08.DOC 37 be appointed within fifteen (15) days of the expiration of the forty-five (45) day appraisal period. If a third appraiser is not selected within said fifteen (15) day period, a third appraiser shall be selected by a presiding judge of the County Superior Court. Within thirty (30) days of selection of the third appraiser, the first two appraisers shall inform both parties in writing of their fair market value determinations. Upon completion of the appointment, the third appraiser shall proceed to determine the fair market value of Tenant's interest in the Lease in accordance with the foregoing standards within forty- five (45) days. The determination made by the third appraiser shall, be binding upon both Lessor and Tenant. Each party shall bear the expense of the appraiser appointed by that party (or the appraiser selected for such party by the other party in the event one party fails to timely select an appraiser) and one-half the expense of the third appraiser, if appointed. For the purposes of this Section 33. the value of Tenant's interest in the Premises shall include, but is not limited to, (a) the residual value of its leasehold interest, valued without the Improvements on the Premises and valued as if the Lease were not to be canceled, and (b) the fair market value of Tenant's Improvements, were they to remain on the Premises. Consideration shall also be given to Lessor's current pro rata interest in the Improvements as described in Section 24.C, if any. Tenant shall be entitled to payment of the amount fixed by the above appraisal method as of the date Lessor acquires full title, control and possession of the Premises. Tenant shall have no right to recover the value of its Improvements in the event that the Lease is terminated as the result of Tenant's Default or for any reason other than as specified in this Section 33. 34. FINANCING OF LEASEHOLD ESTATE Subject to the conditions set forth below, Tenant shall have the right to encumber its leasehold estate in the Premises ("Leasehold Estate"), and/or the Improvements thereon, with only one.Mortgage (as defined, below) at any one time. For example, Tenant may subject only the Leasehold Estate to a Mortgage, or Tenant may obtain one Mortgage covering both the Leasehold Estate and the Improvements, but Tenant shall not subject the Leasehold Estate and the Improvements to separate:Mortgages at the same time. Further, Tenant may not then take out additional Mortgages, such as second loans, on either the Leasehold Estate or the Improvements, or both together. Tenant shall have the above rights to finance, subject to the following terms and conditions: A.

Accordingly, because Section l O.E of the Lease already contemplates that the County, Owner and the Developer shall enter into a consent, nondisturbance and attornment agreement, this Agreement shall not be deemed to be an amendment or modification of the Lease but instead shall be deemed to be an implementation of the Lease. NOW, THEREFORE, in consideration of the covenants of the Parties herein and other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the Parties hereby agree as follows: AGREEMENT 1. Consent. The County hereby consents.to the Hangar Sublease and, subject to the provisions of Section 3 below, agrees that Owner's peaceful and quiet possession of the Unit 536341313405v4 1 shall not be disturbed by the County's exercise of its rights or remedies under the Lease.

In the event the Developer shall default in the performance of its obligations to the County under the Lease (whether or not the County terminates the Lease), and if such default continues uncured after the expiration of any applicable notice or grace period, the County may, at its option and by notice to the Developer (i) elect to receive and collect, directly from Owner, all rent and any other sums owing and to be owed under the Hangar Sublease, as further set forth in Section 3(a), below, or (ii) elect to succeed to the Developer's interest in the Hangar Sublease and cause Owner to attom to the County, as further set forth in Section 3(b) below.

The County shall credit the Developer with any rent received by the County under the assignment set forth above, but the acceptance of any payment on account of rent from Owner as the result of any default under the Lease shall in no manner whatsoever be deemed an attornment by, the County to Owner or by Owner to the County, nor shall the receipt of rent by the County be deemed a. . waiver by the County of any provision of the Lease or serve to release the Developer from any liability under the terms, covenants, conditions,. provisions or agreements of the Lease. Notwithstanding the foregoing, any other payment of rent from the Owner directly to the County, 53634\313405v4 2 regardless of the circumstances or reasons therefor, shall in no manner whatsoever be deemed an attornment by the Owner to the County in the absence of a specific written agreement signedby the County to such an effect or the satisfaction of the conditions to Owner's attornment set forth in Section 3(b)below. (b) Non-Disturbance and Attornment. If the Lease is . terminated or cancelled prior to the end of its Term (as such term is defined in the Lease), then so long as Owner is not in default under the Hangar Sublease beyond any applicable cure period afforded Owner thereunder, then (i) the County shall recognize Owner's subleasehold estate under the Hangar Sublease for the remaining balance of its term plus any extensions thereof effected in accordance with the terms of the Hangar Sublease, (ii) Owner's rights under the Hangar Sublease shall not be affected, and Owner's possession and occupancy of the Unit under the Hangar Sublease shall not be disturbed, and (iii) the Hangar Sublease shall continue in full force and effect and Owner shall automatically attorn to the.County as Owner's landlord under the Hangar Sublease.

Existing Conditions and Setting.The approximately 13.97-acre irregularly-shaped project site is generally flat Table 1: Existing Development and consists of undeveloped grasslands to the west and Use I Square Footage developed areas to the east.Existing development includes i Structures 14,735 four County-owned executive(large aircraft)hangars,tie- Pavement 47,020 downs ace and two structures current] used b the I Tarmac ayiParkingl space, Y Y I Tarmac 135,170 1 Concord Flying Club and Mount Diablo Pilots Gravel Surfaces 119,750 Association.Approximately 31 aircraft are currently stored Concrete Surfaces 1,720 at the project site.' Table 1 shows the total square footage Landscaping 4.950 of existing development on the project site. Access to the Total 323.345 site is currently provided by Buchanan Field Road, a north- Source:CCR Hangars I LLC,2007. south roadway which runs through the center of the site, connecting Center Avenue to the south to Sally Ride Drive to the north. Undeveloped.areas of the project site currently comprise approximately 6.6 acres. A section of a south- north running open drainage channel,which parallels Marsh Drive, crosses the southern portion of the site. Developed areas ofthe.site drain west to this channel through an open drainage channel generally running across the center of the site. The project site is located within unincorporated Contra Costa County and within the City of Concord's Sphere of Influence and Planning Area Boundary. The project site is designated Public/ Semi-Public(PS)in the Contra Costa County General Plan and Public/Quasi-Public in the City of Concord General Plan.The site is.zoned Unrestricted(U)on the Contra Costa County Zoning Map. Proposed Project. CCR Hangars I LLC(project proponent)proposes to construct up to 160;000 square feet of airplane hangar space including up to 30,000 square feet of attached office bungalows, and up to 20,000 square feet of airport administration building space on the project site. As an alternative to construction of the proposed administration building,the project proponent may construct a smaller administration building of up to.2,200 square feet. These and associated site improvements are described below.Figure 4 depicts the conceptual site plan for the proposed project. Figure 5 depicts the alternative site plan with the smaller administration building. a. Hangar/Office Bungalows.The proposed project would construct approximately 43 for-sale aircraft hangars in four different sizes(45 x 40 feet, 50 x 50 feet, 60 x 60 feet, and 80 x 80 feet). These hangars would accommodate a variety of aircraft, including single piston/light twin, turbo prop/srnall- to mid-sized business jets, and a few mid-sized business jets. Seventeen(17)of the hangars would include attached one-to two-story unfinished office bungalows totaling up to 30,000`square feet; 12 of these would include an attached two-car garage. Individual occupants would have the option of improving the office bungalows to fit their needs, which may include development of a bathroom/ shower, flight planning room;media room,pilot lounge, office space and/or a rest area.

LSA ASSOCIATES.IINC. — CCR HANGARS 1 LLC PROJECT AT BUCHANAN FIELD AIRPORT DECEMBER 2DD7 INITIAL STUDY/MITI'GATED NEGATIVE DECLARATION Figure 6 depicts conceptual elevations for the office bungalow and hangar buildings. These structures would not exceed 45 feet in height. Based upon early marketing efforts conducted by the project proponent, it is anticipated that approximately 75 percent of aircraft to be stored at the project site would be drawn from aircraft owners already based at the Airport. b. Airport Administration Building.The proposed project would develop a two-story airport .administration and aviator's lounge/conference center on the southern 1.26 acres of the site. This site would be leased by the County to the project sponsor with the potential for ownership. This building would contain approximately 7,275 square feet of administrative office space for up to 20 employees, 3,300 square feet of community/public meeting space, and a 2,500 square foot hangar for vehicle and equipment storage(up to a total of 20,000 square feet). This building would not exceed 45 feet in height. Conceptual elevations for the administration building are shown in Figure 7. If it is determined by either the project proponent or the Airport that it is not feasible to construct the administration building,then the project proponent may construct a smaller, single-story airport lounge/conference center of up to 2,200 square feet on outlot 2 in lieu of the larger building. The alternative site plan, depicted in Figure 5, includes a realignment of the boundary between lease lot one and lease lot two,avoiding development over the drainage ditch that passes underneath Center Avenue. As a result,re-alignment of the north-south drainage channel along Marsh Drive would not occur. This building,if constructed, would be conveyed to the County upon completion to best ensure public access/use. C. Circulation and Parking.Vehicular ingress and egress to the project site would be provided by new driveways connecting to Center Avenue on the south and Sally Ride Drive on the north. A private roadway would run the length of the western border of the site,parallel to Marsh Drive. This roadway would provide access to surface parking spaces located in front of the hangar areas. The proposed project would provide a total of 160 parking spaces, including: 88 surface parking spaces along the perimeter of the hangar area, 24 parking spaces within the two-car attached garages, and 48 surface parking spaces associated with the administration building. If the smaller administration building is constructed(see Figure 5),a total of 148 parking spaces would be provided. Approximately 181,340 square feet of new tarmac area(net increase of 46,170 square feet)would be located at the eastern section of the site. The tarmac area would provide aircraft access from Taxiway E to the hangars area. d. Utilities,Infrastructure, and Other Site Improvements.The proposed project would develop additional site improvements including water,wastewater,electrical, and telecommunications connections. The proposed project would also alter the existing drainage system on the site. Proposed improvements are discussed below. Final utility and infrastructure locations and connections and site drainage would be reviewed and approved by the appropriate agencies prior to issuance of construction permits for the proposed project. Water. A 12-inch water line currently runs from approximately thesoutheastem section of the site to approximately the northwestern comer of the site. The proposed project would properly abandon a section of this water line in accordance with Contra Costa County Water District(CCWD).

CCR HANGARS 1 LLC PROJECT AT BUCHANAN FIELD AIRPORT DECEMBER 1007 INITIAL STUDY/MITIGATED NEGATIVE DECLARATION requirements.An 8-inch water line is also located along the northern boundary of the site. A new 12- inch water line would be located beneath the private roadway at the western section of the site. This new water line would connect to the existing water lines beneath Taxiway E and at the northwest corner of the site. CCWD would construct this new water line,to be financed by the project proponent. Wastewater.An existing 8-inch sanitary sever line is located at the northern boundary of the site. The proposed project would properly abandon a section of this line and connect to the existing line with a reconfigured 8-inch line located beneath the parking areas at the northern section of the site. Electrical and Telecommunications. Electrical and telecommunications services would be extended onto the project site. Existing overhead lines are located on the east side of Marsh Drive. The proposed project would connect to existing service points along Marsh Drive and would likely be underground. Storm Drainage. As previously discussed, several open drainage areas currently cross the southern section of the project site.An existing 30-inch storm drain currently terminates at the center of the project site. This drain and open drainages convey storm water from the taxi.and runways areas west towards the open drainage channel which runs parallel to Marsh Drive. The 30-inch storm drain would be reconfigured to accommodate the proposed building locations. This new storm drainage line would convey stormwater from the airport infield to.the open drainage channel parallel to Marsh Drive. Opportunities for stomawater quality and hydrograph modification'measures exist both on the east side of the project site in the Airport infield and on the west side of the site. Roof drainages from all buildings, as well as drainage from paved areas would be directed to an appropriately sized integrated management practice(IMP)storm drainage systems(i.e.,bio-filtration swales). Once stormwater runoff has been treated and sufficient hydrograph modification has taken place, stormwater flows would be discharged into the existing drainage channel along the east side of Marsh Drive, adjacent to the project site. e. Demolition, Construction,Grading, and Phasing. The proposed project would remove the six existing structures and paving from the project site. Approximately 25,000 cubic yards if fill would be imported.for use on the project site. Construction of the proposed project would be conducted in a single phase. Project construction would occur over a 24-month period and is expected to cormnence by late 2009 with project completion anticipated by 2011. f. Discretionary.Actions.The proposed project would require two discretionary actions by the County including: an Amendment to the Airport Layout Plan and execution of a lease agreement between the County and the project proponent. Approval of a subdivision map may also be required. 2 Hydrograph modification refers to altering the specific flow intensity and duration of water movement,and hence altering the flow characteristics within the channel.

CCR HANGARS 1 LLC PROJECT AT BUCHANAN FIELD AIRPORT DECEMBER 10,07 INITIAL STUDY/MITIGATED NEGATIVE DECLARATION The terms of the lease agreement, as agreed to by the County and the project proponent,are as follows: The County will enter into a long-term ground lease agreement (the Master Lease) with the project proponent pursuant to Which the project proponent may construct aircraft hangars and related office space for sale to third parties as leasehold condominiunrs. The project proponent will record a condominium plan and declaration of Covenants, Conditions, and Restrictions against its ground leasehold estate. The condominium plan will establish the physical boundaries of each leasehold condominium unit and the declaration will establish Maintenance and operation requirements.. Upon close of escrow, each condominium purchaser will receive a leasehold condominium, comprised of(a) a separate interest in airspace(being the.hangar airspace, bounded by the interior surface of the surrounding walls,floors, ceilings, etc.) coupled with an undivided interest in the particular building module in which his or her unit is located(being the physical structure surrounding each of the units in a single building) and(b) an undivided subleasehold interest in the land on which the hangar project is developed. Upon termination of the Master Lease, ownership of the buildings will revert back to the County, as owner of the underlying fee. Upon sell out of the project, the Master Lease will be assigned by the project proponent to the owners association created for the management and operation of the project. This IS/MND is intended to fulfill the requirements of the California Environmental Quality Act (CEQA). Before Contra Costa County can approve the proposed project, compliance with the National Environmental Policy Act(NEPA)is also required. As a result of NEPA, the Federal Aviation Administration(FAA)has developed guidance documents for airport development projects.FAA Order 1050.1E provides FAA policy and procedures to ensure agency compliance with the requirements set forth in the Council on Environmental Quality(CEQ)regulations for implementing the provisions of NEPA. Unless otherwise excepted by the CEQ regulations, all formal actions taken by FAA officials are subject to NEPA review unless statutory law applicable to the FAA's operations expressly prohibits or makes compliance impossible. Actions covered by NEPA•review include grants,loans, contracts, leases, construction,research activities, rulemaking and regulatory actions, certifications,licensing, permits,plans submitted to the FAA wrich require FAA approval,and legislations proposed by the FAA. In this case, the proposed project would require an amendment to the Airport Layout Plan, which requires FAA approval and compliance with NEPA. The three major levels of NEPA review are Categorical Exclusions(CatEx), environmental assessments(EA), and environmental impact statements(EIS).If an action is included in one of the categories of categorical exclusions (Order 1050.1E) and no extraordinary circumstances apply to the proposed action,the FAA can take action without fil,-cher environmental review. It.isanticipated that A the proposed project would qualify for a CatEx under FAOrder 1050.1E. A CatEx is currently being prepared for the proposed project separately from the CEQA review,to satisfy the requirements of NEPA.

Surrounding Land Uses The project site is located within the western portion of the Airport and, as such,is predominantly surrounded by aviation-related development. Surrounding land uses are described below: • North. The project site is bordered to the north by Sally Ride Drive. The area northwest of Sally Ride Drive is currently undeveloped,but is planned for aviation related development. Additional hangar areas are located farther north of the Sally Ride Drive loop. • East. Airport taxiways and runways are located immediately east of the project site. The FAA control tower, aircraft parking aprons, aircraft storage hangars,maintenance hangars, and terminal facilities are located farther east of the runways. • South. The project site is bordered by a parking area south of Center Avenue. Farther south is the Buchanan Fields Golf Course,also located on Airport property. • West. The project site is bordered by future road widening and light rail corridor rights-of-way parallel to Marsh Drive to the west. An open drainage channel which carries stormwater north to Grayson Creek is located within the roadway easement.West across Marsh Drive are a mobile home park located within the unincorporated community of Pacheco and commercial and. industrial uses. Interstate-680 (I-680)is located farther west of the site. 10.

AESTHETICS.Would the project: a) Have a substantial adverse effect on a scenic vista? b) Substantially damage scenic resources,including,but not limited to,trees,rock outcroppings,and historic buildings within a State scenic highway? c) Substantially degrade the existing visual character or quality of the site and its surroundings? d) Create a new source of substantial light or glare which would adversely affect day or nighttime views in the area? a) Have a substantial adverse effect on a scenic vista? (Less-Than-Si,, Impact) Scenic vistas in the vicinity of the project site include views of the Lime Ridge Open Space area, which is over 3 miles southeast of the Airport. Long-range views of Mount Diablo are available to the east. In addition,portions of SR-4 and SR-242—located approximately 1/2 miles north of and 3/4 miles east of the project site,respectively—are designated Scenic Highways and Expressways on the . Contra Costa County General Plan Scenic Routes Plan. Building heights east of the Airport and within the vicinity of the project site generally range between one and three stories in height,while some building heights south of the Airport reach up to six-stories in height. Given the urban built-up nature of the area surrounding the Airport, and the distance of the project site from SR-4 and SR-42, the proposed 45-fo6t tall structures on the project site would not obstruct views of the Lime Ridge Open Space area or existing views from SR-4 and SR-242. In addition,the proposed project would not be tall enough to visually infringe upon large areas of open space or undeveloped hillsides. As a result,the proposed project would have a less-than-significant impact on scenic vistas. b) Substantially damage scenic resources, including, but not limited to, trees, rock outcroppings, and historic buildings within a State scenic highway? (Less-Than-Significant Impact) The only officially designated State scenic highways within Contra Costa County are portions of Highway 24 and Interstate 680.3 The project site is not located within the vicinity of a State scenic highway. However, the SR-4 and SR-242 Scenic Corridors are located approximately 1/2 miles north s California Department of Transportation,2007.California Scenic Highway Program.Website:www.dot.ca.eov/ hq/LandArch/scenic/schwv.html.July.

Scenic Corridors within the County are defined as much of the adjacent area that can be seen from designated scenic roadways.Policies and implementation measures in the Contra Costa County General Plan seek to preserve and protect scenic views within the County-designated SR-4 and SR7242 Scenic Corridors.The General Plan calls for . development controls to be applied to retain and enhance scenic qualities,restrict unsightly use of land, control the height of structures, and provide site design and architectural guidance along these corridors. The proposed project would not be physically adjacent to the SR-4 and SR-242 Scenic Corridors,and would blend in with surrounding urban development. In addition, the proposed project would conform to the height restrictions outlined in Section 864014 of the Contra.Costa County Zoning Code. The proposed project would not remove any trees,rock outcroppings, or historic buildings,resulting in a less than significant impact to scenic resources within the SR-4 and SR-242 Scenic Corridors. c) Substantially degrade the existing visual character or qualit)�of the site and its surroundings? (Less-Tlsan-Si,,niftcaizt Inspact) The project site is characterized by undeveloped grasslands and open drainage channels to the west and several one-story structures and paved areas to the east. Lands to the north, east,.and south of the project site are within the Airport property and are generally characterized by relatively flat open space and runway areas. The golf course area is characterized by slightly hilly terrain and scattered trees. Existing development northeast of the site.consists of one-and two-story buildings, hangar areas, and surface parking lots.West, across Marsh Drive, is a mobile home park. .. The proposed project would develop the project site with one-to two-story hangars/office bungalows, a two-story administration building, and associated surface parking,landscaping, and tarmac areas. The proposed project would not introduce a new land use to the area,but,rather,would build on a pre- existing pattern of development.The proposed project would be visually consistent with the existing character of the Airport and its surroundings. d) Create a new source of substantial light or glare which would adversely affect day or nighttime views in the area? (Potentially Signifcant Unless Mitigation Incorporated) Interior and exterior lighting associated with the new buildings could create new sources of light and glare. However,the project would be required to comply with the use restrictions established by the County's Zoning Code, which prohibit uses which would make it difficult for pilots to distinguish. between airport lights and other lights,result in glare in the eyes of the pilots using the Airport, or impair visibility in the vicinity of the airport. Compliance with these use restrictions would ensure that new light and glare associated with the hangar and tarmac areas facing the taxiways and runways would not be substantial enough to adversely affect day or nighttime views in the area. The northern portion of the proposed hangar and office bungalow areas would face the existing mobile home park along Marsh Drive.The perimeter of the mobile home park is developed with a low fence and several tall palm trees and hedges,leaving views of the project site generally direct and open. Sun reflecting off of the new development could create daytime glare and security lighting could spillover into the residential area.

CCA HANGARS I LLC PROJECT AT BUCHANAN FIELD AIRPORT DECEMBER 2007 INITIAL STUDY/MITIGATED NEGATIVE DECLARATION quality standards. The main purpose of an air quality plan is to bring the area into compliance with the requirements of federal and State air quality standards. To bring the San Francisco Bay Area region into attainment, the Bay Area Air Quality Management District(BAAQMD)has developed the 2005 Ozone Strategy. Air quality plans use the assumptions and projections of local planning agencies to determine control strategies for regional compliance status. Since the plans are based on local General Plans,projects that are deemed consistent with the applicable General Plan are usually found to be consistent with the air quality plans. Development of the proposed project would not result in increased aircraft operations, but would provide aircraft hangar/office bungalow and administrative office:space. This development scenario is consistent with the overall buildout scenario for Contra Costa County envisioned in the County's General Plan. Therefore, the assumptions used in the development of the County's overall vehicle traffic data that was used in the 2005 Bay Area Ozone Plan would be consistent even with development of the proposed project. The proposed project would not result in a significant increase in traffic volumes above that projected in the County's General Plan and would therefore be consistent with Bay Area 2005 Ozone strategy. b) Violate any air quality standard or contribute substantially to an existing or projected air . quality violation?(Potentially Significant Unless Mitigation Incorporated) Short-term air pollution emissions associated with the proposed project would result from construction activities. Short term emissions would be generated by construction activities such as grading and equipment use, while long-term emissions would result from vehicle trips associated with use of the hangars and office space.The discussion below describes potential air quality violations that could occur as a result of the following: construction equipment exhaust emissions; fugitive dust; long-term vehicular emissions; and local carbon monoxide hot spots. Construction Emissions.Development of the proposed project would result in construction activities that would include site preparation,earthmoving, and general construction. These activities could temporarily increase the local concentration of particulate matter. If construction activities associated with the proposed project result in blowing dust, a major source of increased PM10 and PM2.5 concentrations, the project could contribute to the Bay Area's existing particulate matter air quality violation.Implementation of the following mitigation measure would reduce this impact to a less-than- significant level: Mitigation Measure AIR-1: During the excavation,earthmoving, and grading phases of.the proposed project, the construction contractor shall implement the following measures at the project site: • Water all active construction.sites at least twice daily; • Cover all trucks hauling soil, sand, and other loose materials, or require all trucks to maintain at least 2 feet of freeboard; • Apply water three times daily, or apply nontoxic soil stabilizers on all unpaved access routes,parking areas, staging areas at inactive construction sites, or inactive construction sites; and P.CCCi1701\PRODI 1CTSVS-MND1FimhFim11SC1=Wm dm I I I n[WIf17) 19 LSA ASSOCIATES..INC.

The modeling data is included in Appendix A. The emissions from daily vehicle trips associated with the buildout of the development areas are illustrated in Table 2. As shown, long-term vehicular emissions generated by the proposed project would be substantially lower than the BAAQMD's operations thresholds and would have a Iess-than-significant impact on local or regional air quality. Local CO Hot Spots.Local ambient air quality is most affected by carbon monoxide(CO)emissions from motor vehicles.Areas of vehicle congestion create pockets of high CO concentrations called "hot spots." These pockets have the potential to exceed the State 1-hour standard of 20 parts per million (ppm)of CO and/or the 8-hour standard of 9.0 ppm. Monitored levels of CO in the area are 3.2 ppm for 1-hour and 1.5 ppm for 8-hour concentrations. Given the low background levels of CO in the Project vicinity and the low number of vehicle trips associated with the proposed project, impacts related to local CO hot spots are expected to be less-than-significant., The proposed project: 1)is expected to comply with State and federal ambient air quality standards; 2) is consistent with the air quality management policies in the current air quality plans; and 3)would result in emissions that would be below the emissions thresholds established in the BAAQMD's CEOA Guidelines.6 The proposed project would not violate air quality standards or exceed emissions thresholds. c) Result in a cumulatively cons' iderable net increase of any criteria pollutant for which the Project region is non-attainment under an applicable federal or State ambient air quality standard (including releasing emissions which exceed quantitative thresholds for ozone precursors)? (Less-Than-Si,nifrcant Impact) The proposed project is located in'a f deral and State nen-attainment area for 1-hour.ozone emissions and in a State non-attainment area for PMro. The proposed project would cause temporary construc- tion-related emissions (as discussed in Sections IIIb and IIIA),but is not expected to result.in a significant increase in long-term emissions. The BAAOMD CEOA Guidelines state that a project would result in significant emissions(on both the project and cumulative scales)of criteria pollutants if 6 Bay Area.Air Quality Management District, 1999.BAAOMD CEOA Guidelines.

The proposed project would not exceed these emissions. Therefore, development of the proposed project would not result in a substantial cumulative impact in terms of any criteria pollutant. d) Expose sensitive receptors to substantial pollutant concentrations?(Potentially Significant Unless Mitigation Incorporated) Project.construction may expose surrounding land uses to airborne particulates and fugitive dust, as well as a small quantity of construction equipment pollutants(i.e.,usually diesel fueled vehicles and equipment). However, exposure would be limited by the short term nature of construction activities. Additionally,implementation of Mitigation Measure AIR-1 would reduce impacts to a less-than- significant level. e) Create objectionable odors affecting a substantial number ofpeople? (Less-Than-Significant Impact) Some objectionable odors may be generated from the operation of diesel-powered construction equipment and/or asphalt paving during construction of the project. However,these odors would be short term in nature and would not result in permanent impacts to surrounding land uses, including sensitive receptors in the vicinity of the project site. Therefore,no significant impacts related to objectionable odors would result from the proposed project.

Existing Site Conditions The western portion of the project site consists of an undeveloped parcel dominated by ruderal grassland. Dominant grass species include Italian ryegrass(Lolium multij7orunt),ripgut grass(Bromus diandi-us),Mediterranean barley(HO7-deUM ntarinunt ssp.gussoneanum), and wild oat(Avera fatua), with winter vetch(Vicia villosa),mustard(Brassica sp.),wild radish(Raphanus sativa),and field. bindweed(Convovulus arvensis)comprising the majority of ruderal (i.e.;weedy)herbaceous cover. Vetch,in particular,forms dense ground-spreading mats in several portions of the parcel. A north- south drainage channel along the western edge of the parcel as well as an east-west tributary channel that drains the airport to the east support hydrophytic plant species including cattail (Typha sp.), bulrush(Sci7TUS sp.),nutsedge(C)perus eragrostis), saltgrass(Distichlis spicata), and rabbit's-foot grass (Polypogoll monspeliensis). The portion of the channel south of Center Avenue contains similar hydrophytic vegetation to that described above,with the adjacent upland to the east supporting ruderal grassland. A single eucalyptus (Eucal)ptus sp.)tree is present south of Center Avenue next to the drainage channel, and three small ornamental cypress(Cupressus sp.)trees are present at the eastern edge of the parcel adjacent to Buchanan Field Road. The eastern portion of the site consists of existing airport facilities (i.e.,hangars) and associated paved lots and roads.Non-native grassland dominated by Italian ryegrass is present within two small infields near the southern end of the site,while-grassland dominated by wild-oat occurs between the eastern project boundary and the paved access road.A few Monterey cypress(Cupressus macrocm:va)trees have been planted as landscaping next to the northernmost building. The above information was gathered by LSA biologists during a formal wetland delineation on June 11, 2007(included in.Appendix B) and a reconnaissance-level survey on June 14,2007.

Have a substantial adverse effect, either directly or through habitat modifications, on any species identified as a candidate, sensitive, or special status species in local or regional plans, policies, or regulations, or by the California Department of Fish and Game or U.S. Fish and Wildlife Service? (Potentially Significant Unless Mitigation Incorporated) The California Natural Diversity Database(CNDDB)lists seven special-status plant species occurring in the vicinity of the Airport: slender silver-moss(Anomobryum julaceum),big tarplant(Blepharizonia plumose), Diablo helianthella(Helianthella castanea),Congdon's tarplant(Centromadia panyi ssp. congdonii), Contra Costa goldfields(Lasthenia conjugens),Hall's bush mallow(Malacothamnus hallii), and Mt. Diablo fairy lantern(Calochortus pulchellus).7 None of these species have been observed or are expected to occur within the project site due to its highly disturbed condition and consequent lack of suitable habitat. The CNDDB reports five special-status animal species occurring within the general vicinity of the.site: California tiger salamander(Ambystoma californiense), Califomia-red-legged frog(Rana aurora draytonii),Alameda whipsnake(Masticophis lateralis eur),'xanthus),burrowing owl(Athene cunicularia), and pallid bat(Antrozous pallidus).$The California tiger salamander, California red- legged frog, and Alameda whipsnake are listed as threatened under the federal Endangered Species Act(ESA). California tiger salamander and California red-legged frog are not expected to occur on site due to its urban setting,the lack of known breeding records in the site vicinity, and the low habitat value of the on-site drainage channels. The Alameda whipsnake is unlikely to occur on the project site due to the absence of suitable chaparral habitat. Furthermore,Alameda whipsnakes typically occur in foothill landscapes,not in low-elevation areas such as those in the vicinity of the Airport.None of the existing buildings are expected to support roosting pallid bats due to ongoing human activity(i.e., plane repair and storage)within and around the buildings. Although.burrowing owls have not previously been observed on or in the immediate vicinity of the site, suitable habitat is present due.to the presence of California ground squirrels(Spermophilus beecheyi) and their burrows,primarily in the undeveloped parcel between Marsh Drive and Buchanan Field Road. Burrowing owls are a California Species of Special Concern and their nest burrows are protected by the federal Migratory Bird Treaty Act(MBTA) and California Fish and Game Code. The Airport's current practice of delaying mowing of infields and undeveloped areas until June 1 (to minimize the establishment of starthistle [Centaurea sp.] on the infields)9 reduces the likelihood of burrowing owls nesting on site since they typically prefer areas with short vegetation so they can easily scan their surroundings and spot approaching predators.10 The tall grasses and dense ruderal vegetation that characterize the parcel between Marsh Drive and Buchanan Field Road in April and May,when burrowing owls are actively seeking and selecting nest burrows, would severely diminish habitat suitability for this species during the breeding season.However,the site could be used by migrating California Natural Diversity Database(CNDDB),2007.Special-status Species Occurrences from the Walnut Creek 7.5-minute USGS quadrangle.Wildlife and Habitat Data Analysis Branch,California Department of Fish and Game, Sacramento..

If present,burrowing owls could be directly impacted through the destruction of occupied burrows during grading and demolition activities associated with project construction. The following two-part mitigation measure would reduce this impact to a less-than-significant level': Mitigation Measure BIO-1 a: Pre-construction surveys to determine the presence of burrowing owls on or within 500 feet of construction areas shall be conducted by a qualified biologist no more than 30 days prior to the initiation of any construction-related activities. If burrowing owls are observed on or.near the construction area during these surveys,the applicant shall implement an exclusion zone(i.e., an area in which no project-related activities are allowed) around the occupied burrow. During the breeding season of February 1 to August 31, exclusion zones shall consist of a 250-foot radius from the nest burrow.No project activity shall occur within the exclusion area until the young have fledged. During the non-breeding season of September 1 to January 31, exclusion zones shall consist of a 160-foot radius from occupied burrows. Passive relocation of owls,involving the exclusion of owls from burrows through the placement of one- way doors into burrow entrances, may be implemented during the non-breeding season, provided that the California Department of Fish and Game(CDFG)has reviewed and authorized the relocation plan. Mitigation Measure BIO-Ib: If burrowing owls are determined to be present on the project site, the project applicant shall provide 6.5 acres of suitable on- or off-site habitat per pair or non- paired owl displaced by the project,in accordance with CDFG requirements. Suitable habitat may also be provided in the form of credits at a CDFG-approved habitat conservation bank. b) Have a substantial adverse effect 071 any riparian habitat or other sensitive natural c0711n1unity identified in local or regional plans,policies, regulations or by the California Department of Fish and Game or U.S. Fish and Wildlife Service?(No Impact) The project site does not support any riparian habitats or other sensitive'natural communities. The proposed project would have no impact on riparian habitats and other sensitive natural communities. c) Have a substa;liial adverse E,��ct.o:Mede;alprotected wetlands as defined IJy Sec4071.404 of the Clean Water Act(including, but not limited to, marsh, vernal pool, coastal, etc.) through direct removal,filling, hydrological interruption, or other means? (Potentially Significant Unless Rfitigation Incorporated) LSA conducted a jurisdictional delineation of waters of the United States(U.S.) on and within the immediate vicinity of the site on June 11, 2007. Potential waters of the U.S. identified include 28,090 square feet(0.65 acre) of multiple constructed drainage channels with wetland characteristics("other waters" of the U.S.).with a total length of 1,575 feet. The majority of these jurisdictional channels would be affected(i.e.,permanently filled or temporarily disturbed) during project construction. The project design calls for minor alteration of the south-to- north drainage channel along Marsh Drive near the intersection with Center Avenue. This would affect Tributaries B and C (see Appendix B.Figure 3). The design would also result in the removal of approximately 70 percent of each of the east-.west tributary ditches(Tributary A and the non- F.C'L*T17�I•PRODLK.7SJSMI.D�FinaiFneI1S.:ncclL.aAn(IInO^_IN71 24 LSA ASSOCIATES., INC.

However, should the Alternative Site Plan be developed,the proposed project would avoid realignment of the south-to-north channel and would not affect Tributaries B and. C. Implementation of the following mitigation measures would reduce these impacts to a less-than- sienificant level: Mitigation Measure BI0-2a: The project applicant shall obtain the appropriate federal and State permits authorizing the fill of the jurisdictional channels associated with project construction. Impacts to jurisdictional areas shall be mitigated according to appropriate ratios determined by the regulatory agencies (i.e.,U.S.Army Corps of Engineers [Corps], San Francisco Bay Regional Water Quality Control Board[Water Board]). The applicant shall comply with all terms and conditions of the permits and implement a wetland mitigation and monitoring plan (MMP), if required by the agencies. The applicant shall provide a secure funding source for implementation of the plan and long-term maintenance and monitoring of the mitigation area. The MMP must be approved by the Corps prior to implementation. Mitigation Measure BI0-2b: All jurisdictional areas located adjacent to,but outside of,the construction footprint shall be avoided during construction and no fill shall be allowed to enter these areas. Exclusion fencing(i.e., orange plastic construction fence or silt fence)shall be installed to mark the limits of the construction footprint. A biological monitor shall oversee the installation of the fencing and periodically monitor the work area to ensure avoidance of the jurisdictional areas. Mitigation Measure BIO-2c: During project construction, no soil or other construction materials shall be allowed to enter or be stored in any jurisdictional areas. All stockpiled fill and other materials shall be kept at least 50 feet from the edge of jurisdictional areas. Contractors shall implement Best Management Practices(BMPs)to prevent sediment and other potential contaminants from entering jurisdictional areas. d) Interfere substantially with the movement of any native resident or migratory fish or wildlife species or with established native resident or migratory wildlife corridors, or impede the use of native wildlife nursery sites? (Potentially Significant Unless Mitigation Incorporated) No wildlife corridors would be adversely affected by the proposed project. Given its location within a highly urbanized landscape,the project site does not'currently serve as a major wildlife movement corridor.Most of the species that likely use the site are generalists that are adept at moving through urban landscapes. The relatively limited extent of habitat loss that would result from the proposed Project will not affect the ability of these species to move throughthe project vicinity. Species that use the north-south drainage channel for small-scale local movements would still be able to do so after the drainage is re-aligned. Project construction would presumably involve the removal of all existing trees on the site(i.e., eucalyptus next to Center Avenue and ornamental cypress trees next to buildings), as well as wetland vegetation(e,g., cattails)within those portions of the existing drainage channels that will be affected by the project. Both habitats have the potential to support nests of common native bird species. All native birds and their nests,regardless of their regulatory status, are protected under the federal Migratory Bird Treaty Act and California Fish and Game Code.

Implementation of the following mitigation measure would reduce potential impacts to nesting birds to a less-than-significant level. Mitieation Measure BIO-3: If feasible, all vegetation removal shall be conducted during the non- breeding season(i.e., August 1 to February 28)to avoid direct impacts to nesting birds. If such work is scheduled during the breeding season, a qualified ornithologist shall conduct a pre- construction survey to determine if any birds are nesting in the vegetation to be removed. The pre-construction survey shall be conducted within 15 days prior to the start of work from March though May(since there is higher potential for birds to initiate nesting during this period), and within 30 days prior to the start of work from June through July.If active nests are found during the survey,the biologist shall determine an appropriately sized buffer around the nest in which no work will be allowed until the young have successfully fledged. The size of the nest buffer shall be determined by the biologist in consultation with the CDFG, and will be based on the nesting species,its sensitivity to disturbance, and the expected types of disturbance. e) Cor j7ict with any local policies or ordinances protecting biological resources, such as a tree Preservation policy or ordinance? (Potentially Sigtzifzcant Unless!Mitigation Incorporated) Any tree removals associated with the proposed project would be subject to the County's Tree Protection and Preservation Ordinance(Chapter 8.16-6 of the County Code),which defines protected trees as any tree measuring more than 6.5 inches in diameter measured at 4.5 feet above ground, any multi-stemmed tree where the total diameter exceeds 13 inches (also measured at 4.5 feet above ground),or any significant grouping of trees, including groves of four or more trees..Removal of protected trees without a tree permit would conflict with the tree ordinance. Mitieation Measure BIO-4: The applicant shall hire a qualified arboristtt to visit the site and determine whether any of the on-site trees are protected under the tree ordinance. If none of the trees qualify for protected status,no further action would be required. If any of the trees are protected,the applicant shall apply to the Community Development Department for a tree permit in accordance with Article 816-6.8004 of the County's Tree Protection and Preservation Ordinance.. f) Conflict with the prc✓isons-of an adopted Habitat Conservation Plan, Natural Conaniunity Cozzservation Plan or other.approved local, regional, or State habitat conservation plan?

(No Impact) Historical structures within the County are listed on the National Register of Historic Places, as well as with the State of California Office of Historic Preservation(on the California Register). There are no_ known historic structures located within or in the vicinity of the Airport. Existing structures on the project site consist of four County-owned executive hangars and two structures currently used by flying clubs. The two structures currently occupied by the flying clubs were constructed in the late 1940s. These structures consist of hangar/office space and are used as on-site maintenance and storage facilities for private aircraft.The Concord Flying Club has occupied its building since its construction. The Mount Diablo Pilots Association(MDPA)has only occupied the existing structure since the late 1980s or early 1990s. These structures are not considered historic resources under the criteria provided in Section 15064.5 of the CEOA Guidelines. b) Cause a substantial adverse change in the significance ofan archaeological resource pursuant to §15064.5? (Potentially Significant Unless Mitigation Incorporated) There are no known archeological resources at the project site. However,there are over 600 sites within the County that have been recorded with the Archeological Inventory,Northwest Information Center at Sonoma State University. Although the Airport is not located in an archeologically sensitive area due to the urban and built-up nature of the site(as shown on the Contra Costa County Archeo- logical Sensitivity Map), it is possible that previously unknown historic or prehistoric resources could be discovered during grading and excavation work associated with project construction activities. Implementation of the following mitigation measure would ensure that impacts to discovered archeo- logical resources would be less-than-significant: Mitigation Measure.CULT-1: If deposits of prehistoric or historic archeoloo"cal materials are encountered during project activities,all work within 25 feet of the discovery shall be redirected P'CCC�70]1PRODVCfS�1SMl^J�mallFnuI1SC]recklm tlac(IlntvMln7) 27 LSA ASSOCIATES.

(Potentially Significant Unless Mitigation Incorporated) . There are no identified paleontological resources or unique geologic features.or sites within or in the vicinity of the project site. However,there is the potential for paleontological resources to occur at the site and to be adversely affected by project-related construction activities. Implementation of the following mitigation measure would ensure that impacts to paleontological resources are less-than- si enificant: Mitigation Measure CULT-2:If paleontological resources are encountered during demolition, site preparation,or grading activities, all work within 25 feet of the discovery shall be redirected until a qualified paleontologist has assessed the discoveries and,made recommendations.

(Potentially Significant Unless Mitigation Incorporated) Fault Rupture: Fault rupture is displacement of the earth's surface resulting from fault movement associated with an earthquake. The Hayward and San Andreas Faults are the two principally active faults within the Bay Area and are located approximately 15 and 32 miles west of the project site, respectively. Other active faults within the region include the Clayton, Pleasanton,Marsh Creek, West Napa, Calaveras,Rodgers Creek,Greenville, and Verona Faults. The Concord Fault;runs in a northwest-southeast direction immediately east of the Airport,approximately 1/z mile northeast of the project site. The nearest Alquist-Priolo Earthquake Fault Zone extends,approximately1,000 to 2,500 feet wide on either site of the Concord Fault. The project site is not located within the Alquist-Priolo Fault Zone. Therefore,the potential for impacts associated:with fault rapture at the project site are less-than- significant. Groundshaking.The entire San Francisco Bay Area is located in a region of active seismicity. Historically,numerous moderate to strong earthquakes have been generated in northern Califorrila by 13 Stevens,Perrone&Bailey Engineering Company,Inc.,2007.Geoiechnicallnvestigation Ezecutive/Conporate Hangars:Buchanan Field,4h?ort,Concord,CA.July 3.

CCA HANGARS 1 LLC PROJECT AT RUCHANAN FIELD AIRPORT DECEMBER 2007 INITIAL STUDY/MITIGATED NEGATIVE DECLARATION several major faults and fault zones in the San Andreas Fault Zone system. The level of active seismicity results in classification of the San Francisco Bay Area as seismic risk Zone 4(the highest risk category)in the California Building Code. The proposed project would result in an increase in the number of people, structures and improve- ments exposed to seismic hazards. Because of the proximity of the project site to nearby active and potentially-active faults,moderate to strong ground shaking could occur at the site as the result of an earthquake on any of these faults. The aggregate probability of the occurrence of one or more mag- nitude 6.7 plus earthquakes in the San Francisco Bay Area over the next 25 years is estimated at 62 percent.14 Groundshaking potential is estimated on a worst-case basis by taking the maximum expected earthquake and designing for the peak accelerations that it could generate. The project site has a 10 percent probability of exceeding a peak ground acceleration of about 0.6g in 50 years.15 The risk of structural damage from ground shaking is reduced through adherence to design and materials standards set forth in building codes. The Uniform Building Code (UBC)requires use of seismic parameters which allow the structural engineering analysis for buildings to be based on soil profile types. Compliance with building and grading regulations and conformance with Title 24 specifications for seismic design would reduce the potential for ground shaking impacts. However, to ensure that the potential adverse effects of ground shaking are reduced to a less-than-significant level, the following mitigation measure shall also be implemented: Mitieation Measure GEO-1: The project proponent shall implement the earthquake design criteria provided in the geotechnical investigation prepared for the project. The County Engineering Services Division shall ensure that these criteria are incorporated into the final design plans prior to issuance of a building permit for the proposed project. It is acknowledged that seismic hazards cannot be completely eliminated, even with implementation of site-specific geotechnical methods and advanced building practices. However, exposure to seismic hazards is a generally accepted part of living and working in the seismically active areas of Califomia and therefore the mitigation measure described above reduces the potential hazards associated with seismic activity to a less-than-significant level. Ground Failure and Liquefaction. Soil liquefaction is a phenomenon primarily associated with saturated soil layers located close to the ground surface. These soils lose strength during ground- shaking. Due to the loss of strength,the soil acquires a"mobility" sufficient to permit both horizontal and vertical movements. Soils that are most susceptible to liquefaction are clean,loose, uniformly graded,saturated, fine-grained sands that lie relatively close to the ground surface. However, loose sands that contain a significant amount of fines (minute silt and clay fraction)may also liquefy. The project site is underlain by Holocene basin deposits that have been previously mapped as very fire silty clay to clay deposits occupying flat-floored basins at the edge of alluvial fans adjacent to bay mud. According to the Association of Bay Area Governments (ABAG)and the U.S. Geological j4 Ibid. is Ibid. P'L('CU7:i1�PROIN 4"]SVSM!JDF'uulFim115.'hxL'Jiatdoc(1 Il.�N20D'7J 31 LSA ASSOCIATES. INC CCR HANGARS I LLC PROJECT AT BUCHANAN FIELD AIRPORT DECEMBER 2007 INITIAL STUDY/MITICATED NEGATIVE DECLARATION Survey,the project site is located in.an area mapped as having a high potential for liquefaction.16 As discussed above,the proposed project would be constructed in compliance with applicable construc- tion codes and requirements intended to mitigate any adverse impacts resulting from ground failure and liquefaction. Implementation of Mitigation Measure GEO-1 would reduce any potential impacts associated with ground failure and liquefaction to human safety to a less-than-significant level. Landslides.The project site is located on generally flat topography,with no risk of landslides or mudslides. b) Result in substantial soil erosion or the loss of topsoil? (Potentially Significant Unless Mitigation Incorporated) The potential for soil.erosion and loss.of topsoil exists during the period of earthwork activities and between the time when earthwork is complete and new vegetation is established, or asphalt is laid. A Storrnw,ater Pollution Prevention Plan(SWPPP) and Erosion Control Plan are a routine requirement for projects requiring grading permits. The SWPPP identifies the"best management'practices" that are most appropriate for the site, and the erosion and sedimentation control plan,which is required for. final grading permits,provides the details of the erosion control measures to be applied on the site and maintained throughout the winter rainy season.As recommended in Mitigation Measure HYD-1 a (see Section VII.a,below), implementation of a SWPPP and erosion and sedimentation control plan, to be submitted prior to and approved by the County prior to issuance of a grading permit,would reduce the impacts of soil erosion and the loss of topsoil to a less-than-significant level. c) Be located on a geologic unit or soil that is unstable, or that would become unstable as a result of the project, and potentially result in on-or off-site landslide, lateral spreading, subsidence, liquefaction or collapse? (Potentially Significant Uizless Mitigation Incorporated) As described in Section VI.a, the soils that underlie the project site have a high potential for lique- faction during an earthquake. Site soils may also be subject.to subsidence, lateral spreading,or collapse.Implementation of Mitigation Measure GEO-1 would ensure that potential'impacts fi-om soil instability would be reduced to a less-than-significant level. Lateral spreading occurs when soils liquefy during an earthquake and the liquefied soils with the overlying soils move laterally to unconfined spaces(such as the adjacent drainage channel). Due to the relatively shallow depth to the bottom of the drainage channel and limited extent of the liquefiable soils,the potential for building damage as a result of lateral spreading adjacent to the drainage channel is love(. As described in Section VI.a,the project site is located on generally flat topography,with no risk of landslides or mudslides. 's Ibid.

(Potentially Significant Unless Mitigation Incorporated) Subsurface borings at the project site indicate that fill materials at the site are potentially compressible. The more sandy fills were relatively non-expansive;however,the more clayey fills were moderately to highly expansive. The near-surface,more clayey native materials have a high plasticity and high potential for expansion. Expansive clay soils are prone to heave and shrink movements with changes in moisture content and,consequently,must be considered in the design of graded surfaces,foundations, drainage features,and landscaping. The effect of compressible soils can be adequately controlled with appropriate structural design of foundations and civil design of surface grades and gradients for gravity-flow pipes. Implementation of Mitigation Measure GEO-1 would ensure that potential impacts from potentially expansive soils are reduced to a less-than-significant level. e) Have soils incapable of adequately supporting the use of septic tanks or alternative waste water disposal systems where sewers are not available for the disposal of waste water?(1Vo Impact) Wastewater conveyance and treatment for the proposed project would be provided by the Central Contra Costa County Sanitary'District(CCCCSD).

(Less-Than-Significant Impact) The proposed project would develop aircraft hangars, office bungalows, and an administration building on the project site,within the existing boundaries of the Airport.No fueling facilities are proposed;however, general aircraft maintenance activities on the project site may require the use of oils;fuels,lubricants,and paints. The Airport is identified as a hazardous land use in the Contra Costa County General Plan. Facilities such as the Airport that use, store, or handle hazardous materials in quantities greater than 500 pounds, 55 gallons, or 200 cubic feet are required to prepare a Hazardous Materials Business`Plan(HMBP). The HMBP is intended to provide detailed hazardous material.uses to emergency responders. HMBPs must remain current and at a minimum must be reviewed every three years. As future development projects are approved,the HMBP is updated. Adherence to applicable regulatory requirements (e.cr requirements of HMBPs,including employee training and emergency response,hazards communica- tion training, and injury and illness prevention plans)would mitigate potential impacts from routine transport,use, or disposal of hazardous materials at the project site.Although these plans would not 17 Environmental Resources Management,2007.Phase l Environmental Site Assessment,Buchanan Field Airport, Sally Ride Dave and Marsh Drive, Concord, CA.July 13.

(Potentially Significant Unless Mitigation Incorporated) During aircraft operations and maintenance activities at the project site, existing hazardous materials regulations would reduce the potential impacts of a hazardous materials.release to a less-than- significant level(see Section VII.a, above). Development of the proposed project could result in exposure of construction workers to hazardous materials. Five potential sources of hazardous materials contamination have been identified at the project site, and are discussed below. Pipeline Hazards.No underground storage tanks(USTs)or aboveground storage tanks(ASTs)are currently known to occur on the project site. A 550-gallon UST containing 80-octane aviation gasoline was previously located behind the MDPA building and removed in 1990. A former military refueling pit was observed behind the MDPA building. The pit was historically connected by piping to off-site fuel USTs located between Marsh Drive and Sally Ride Drive. The off-site USTs were.removed during the 1950's;however,the piping is still likely present underground.No documentation of UST or pipeline removal was available for the Phase I performed for the project site. Potential rupture of the pipeline,which may still be connected to the UST, could result in a significant release of hazardous materials during project grading and construction activities. Mitigation Measure HAZ-1.The exact location of on-site pipelines shall be identified and historical documentation of UST removal provided to the Contra Costa County Community Development and County Health Services Departments prior to issuance of grading or construction permits for the proposed project. In the event that the appropriate documentation of UST and piping removal cannot be obtained,a geophysical survey shall be conducted to determine the potential presence of a UST and associated piping. Agricultural Land Use and Vegetation Management. The Contra Costa County Public Works Department regularly sprays the undeveloped portion of the project site with chemical defoliant. An environmentally sensitive defoliant is used to remove larger leaves so the grass can be easily mowed. Details of historical spraying activities are unknown. Additionally,the project site has historically been used for agricultural purposes(prior to development of the Airport). These historical uses likely included the use of pesticides, fertilizers and other agricultural chemicals. Although most agricultural chemicals used today have a short persistence, some agricultural chemicals used in the past may remain in shallow soils,potentially posing a health risk to those persons who may come into direct contact with the soils. Oil Staining.Localized oil staininj was observed on the floors of specific storage and maintenance areas inside existing structures and outside underneath parked aircraft on the project site. The asphalt ground and flooring throughout the project site appeared in good to fair condition,with some cracking. and patched areas. Oils and other materials used at the site may have leached through these cracks and resulting-in soil contamination. P:ICL(nen]%PRC)DIKTSVCMND�Fiml\Fiml]SO=Uin dx(I I AOL1200 t) 35 LSA ASSOCIATES. INC. CCR HANGARS 1 LLC PROJECT AT BUCHANAN FIELD AIRPORT DECEMBER. 2007 INITIAL STUDY/MITIGATED NEGATIVE DECLARATION Septic System. A septic system associated with the executive hangar area was removed and replaced with a holding tank. The bathroom inside the hangar is currently connected to the holding tank, which is behind the hangar along Buchanan Field Road. The contents of the tank are pumped out on a regular basis. If chemicals besides sanitary wastes have been released into the tank,potential leakage of the tank contents into the subsurface may have occurred,potentially contaminating site soils. Implementation of the following twlo-part mitigation measure would reduce potential impacts assoc- iated with potentially contaminated soils and potential airborne contaminants to a less-than-significant level. Mitigation Measure HAZ-2a: Prior to issuance of grading or construction permits,a Phase H Environmental Site Assessment for both the developed and undeveloped portions of the project site shall be conducted by a qualified environmental professional to assess the presence and extent of contamination at the site. These investigations shall be conducted in conformance with State and local guidelines and regulations. If the results of subsurface investigations(s) confirm the presence of hazardous materials, site remediation may be required to protect the health and safety of future site users,with oversight by the applicable State or local regulatory agencies. Specific remedies would depend on the extent and magnitude of contamination and the requirements of the regulatory agencies. The investigation report and certification requiring further actions(if necessary)shall be completed and submitted to the County Community Development and County Health Services Departments for review and approval. Mitigation Measure HAZ-2b: Construction activities shall only occur in accordance with a site- specific health and safety plan prepared by a certified industrial hygienist. The plan shall include provisions for monitoring exposure to construction workers,delineate procedures to be under- taken in the event that contamination is identified above action levels, and identify emergency procedures and responsible personnel. The health and safety plan shall include performance standards identified to minimize the effects of air-borne contaminants(for example, stopping work on days of high wind velocities, limiting excavation areas,or wetting down surfaces). Construction workers in contaminated areas shall be required to receive hazardous materials training in accordance with federal and State.re.jul-ations. Asbestos and Lead Containing Materials. Buildings constructed prior to 1980 may contain lead- based paint(LBP)and asbestos-containing building materials(AGMs). Existing structures on the project site were constructed between the 1940's and 1960's. Although LBP and ACMs in good condition would not be expected to present an immediate health risk, lead and asbestos particles could potentially be released to the air during building demolition,which could pose a health risk to construction workers.Implementation of the foiiowing mitigation measure would reduce potential impacts due to release of lead and asbestos to a less-than-significant level. Mitigation Measure HAZ-3::Prior to issuance.of a construction or demolition permit affecting site structures,a lead-based paint and asbestos-containing material survey shall be performed at the structure by a qualified environmental professional. Based on the findings of the survey, all loose and peeling lead-based paint and identified asbestos hazards.shall be abated by a certified contractor in accordance with federal and State requirements.

However,the project site itself is.not identified on a list of hazardous materials sites compiled pursuant to Government Code Section 65962.5. Development of the proposed project would not disturb any known contaminated sites on Airport property. e) For a project located within an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use airport, would the project result in a safety hazard for people residing or working in the project area? (Less-Than-Significant Impact) The proposed project would be developed in accordance with FAA regulations. These regulations would reduce potential safety hazards to a less-than-significant level. For a project located within the vicinity of a private airstrip, would the project result in a safety hazard for people residing or working in the project area? (No Impact) . No private airstrips are Iocated within the project vicinity. g) Impair implementation of or physically interfere with an adopted emergency response plan or emergency evacuation plan? (No Impact) Proposed development at the projects site would not interfere with emergency response or emergency evacuation plans. h) Expose people or structures to a significant risk of loss, injury or death involving wildland fires, including where wildlands are adjacent to urbanized areas or where residences are intermixed with wildlands? (No Impact) Land uses adjacent to the project site include developed urban areas.Although the land directly north of the Airport consists of undeveloped open space, this area is separated from the Airport by SR-4 and is itself surrounded by urban uses. Therefore,the proposed development would not be exposed to a high wildfire risk. P:k'CGY�7��IWRUUIK'fSJSMiJD�FwIVi'all$(Tecgicttloc(Iln(1nJq"!) 37 LSA ASSOCIATES. INC.

The Drainage and Flood Control Study serves as a plan to mitigate and control incremental runoff associated with future development at the Airport. The HydrologyStudy is specific to the proposed project and outlines the application of the Drainage and Flood Control Study to this area of the Airport. The Hydrology Study is included as Appendix E of this report. . a) Violate any water quality standards or waste discharge requirements? (Potentially Significant Unless Mitigation Incorporated) The following subsections discuss impacts to water quality associated with construction and operation of the proposed project. Construction Period Impacts. Excavation,grading, and construction activities associated with the proposed project would lead to temporary disturbance of surface soils and removal of vegetative cover. During the construction period,excavation and grading activities could result in exposure of soil to runoff, potentially causing erosion and mobilization of sediment in the runoff. Soil stockpiles and excavated parcels would be exposed to runoff and, if not managed properly,the runoff could cause erosion and increased sedimentation in drainages and detention areas within the Airport infield, the County drainage channels, Grayson Creek and Pacheco Slough. The accumulation of sediment could result in blockage of flows,potentially resulting in increased localized ponding or flooding. The potential for chemical releases is present at most construction sites. Once released, substances such as fuels, oils,paints, and solvents could be transported to nearby surface waterways and/or groundwater in stormwater runoff,wash water, and dust control water,reducing the quality of the receiving waters. Operation Period Impacts.The intensified land uses in the project area would result in increased vehicle use and potential discharge of associated pollutants. Leaks of fuel or lubricants,tire wear, and fallout from exhaust contribute petroleum hydrocarbons,heavy metals, and sediment to the pollutant load in runoff being transported to receiving waters. Runoff from landscaped areas may contain residual pesticides and nutrients. Long-term degradation of runoff water quality from the project site. could adversely affect water quality in receiving water bodies. The proposed project is subject to the San Francisco Regional Water Quality Control Board's (Water Board)National Pollutant Discharge EIimination System(NPDES)C.3 provisions. C.3 provisions are separate from, and in addition to,requirements for erosion and sediment control and for pollution prevention measures during construction. The C.3 provisions require applicable development projects to capture and treat operational stormwater runoff prior to discharge to receiving water bodies to the maximum extent practicable.Furthermore,they establish minimum thresholds for the quantity,of site runoff that must pass through accepted treatment controls.

The project shall incorporate landscaping features into the drainage design and shall route runoff from impervious surfaces toward swales or landscaped areas before ultimate discharge to the drainage channels tributary to Grayson Creek. The report shall also specify on-going maintenance and inspection requirements for new stormwater management facilities as well as the responsible parties and funding sources for the required maintenance activities. b) Substantially deplete groundwater supplies or interfere substantially with groundwater recharge such that there would be a net deficit in aquifer volume or a lowering of the local groundwater table level(e.g., the production rate ofpre-existing nearby wells would drop to a level which would not support existing land uses or planned uses for which permits have been granted)? (Less-Than-Significant Impact) The Airport is underlain by the Ygnacio Valley groundwater basin. Aquifers in the basin are hydraulically connected to the Sacramento River. Although no use of groundwater is proposed for the proposed project,some dewatering may be required during construction activities.Any dewatering activity would be expected to be temporary and affect only the uppermost water-bearing zone,not the deeper regional aquifer. . The proposed project would increase the percentage of impervious surfaces(e.g.,paved surfaces, buildings)at the site. The 13.97=acre project site would see a loss of 5.35 acres of open space and landscaping(roughly 80 percent of the existing open space and landscaping on the site);leaving approximately 1.25 acres of open space and landscaped areas within the project boundary. 21 This loss of pervious surface could have an impact on groundwater recharge if not for the fact that it is offset by the properties of the native soils at the project site. Sol] cover at the project site is entirely Omni clay loam(0a)Z2,classified under the Natural Resources Conservation Service(NRCS) hydrologic soil group system(HSG)23 as a D-type soil. As such,the decrease in open space and landscaped areas would not be expected to significantly reduce infiltration of precipitation to the . regional aquifer system. For these reasons, the.proposed project would have a less-than-significant impact on groundwater recharge. c) Substantially,alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river, in a manner which would result in substantial erosion or siltation on-or off-site?

CCR HANGARS 1 LLC PROJECT AT BUCHANAN FIELD AIRPORT DECEMBER 2007 INITIAL STUDY/MITIGATED NEGATIVE DECLARATION Storm drains serving the Airport are maintained by the Contra Costa County Public Works Department. Currently, drainage from the project area flows east to west either overland or through two east-west ditches tributary to a larger sub-regional engineered drainage channel that flows south to north along the east side of Marsh Drive. The draft wetland delineation prepared for the project site refers to the southern tributary ditch as Tributary A,while'the northern non jurisdictional ditch is indicated by a dashed line(see Appendix B,Figure 3). The sub-regional open drainage channel flows approximately 3,900 feet north of the project site to join Grayson Creek.'Grayson Creek; an improved flood control channel operated and.maintained by Contra Costa County Flood Control and Water Conservation District(Flood Control District),likewise flows north,joining Walnut Creek and discharging into Pacheco Slough and Suisun Bay. Grayson Creek flows a distance of roughly four miles to Suisun Bay with a drop of roughly 18 feet, equivalent to an average slope of less than 0.09 percent. The project design calls for minor alteration of the south-to-north drainage channel along Marsh Drive near the intersection with Center Avenue. This-would affect Tributaries B and C(see Appendix B, Figure 3).The design would also result in the removal of approximately 70 percent of each of the east-. west tributary ditches(Tributary A and the non jurisdictional drainage ditch). Development of the Alternative Site Plan would avoid realignment of the south-to-north channel and would not affect Tributaries B and C. Given the location of the project site, on relatively level terrain.in the lower reaches of the watershed and discharging into County-maintained engineered channels development of the proposed project, would not be expected to result in a significant increase in erosion or siltation on- or off-site. Additionally,implementation of the measures called for in HYDRO-lb would minimize any such potential to a less-than-significant level. Grading activities associated with the proposed project would occur in relatively flat areas. Construction-period stormwater controls required in HYDRO-1 a would minimize the erosion and runoff potential from the proposed project during construction activities.' d) Substantially alter the existing drainage pattern of the site or area, including through the alteration of the course of a stream or river-, or substantially increase the rate or amount of surface runoff in.a manner which would result in flooding on- or off-site?(Potentially Significant Unless Mitigation Incorporated) Historically,the Airport drainage system has.experienced difficulties in maintaining free open surface channel flow during larger storms (such as-the 10-year event)due to the high water level of receiving water bodies(Grayson Creek to the west and Walnut Creek to the east). The low-lying open space areas between runways and taxiways to the east of the project site often function as detention basins during storms. Some of these locations were specifically designed as detention basins in the early 1990s. The drainage design for the proposed project utilizes the depression to the east of the project site(in the Airport infield) for this purpose. The use of the depressed infield areas for detention is . considered adequate as long as the backwater surface elevations do not overtop and flood the runways and taxiways. The proposed project would replace more than 70 percent'of the existing east-west ditches(Tributary A and the non-jurisdictional drainage ditch) with underground drainage pipes and after the alignment of the south-to-north channel at the southern end of the site. This could exacerbate existing flooding P.•GY:(L7J:PRO,:.C�1'SUSMNDv iul•An'eIlSl:licck:i9 Doc(11/.I(t2fK17) 42 LSA.ASSOCIATES. INC. CCR HANGARS I LLC PROJECT AT BUCHANAN FIELD AIRPORT DECEMBER 2007 INITIAL STUDY/MITIGATED NEGATIVE DECLARATION problems downstream. Development of the Alternative Site Plan would avoid realignment of the south-to-north channel. The proposed project would also increase the amount of impervious surface at the site and therefore may affect the rate and amount of surface runoff. Increased runoff volume could exacerbate down- stream flooding problems during larger storm events. However,the proposed project is not expected to result in hydromodification in the downstream channels(effects caused by storm events smaller than the 2-year recurrence event)due to the low gradient and engineered nature of the channels receiving runoff from the site. Compliance with Provision C.3,required by Mitigation Measure HYDRO-lb, along with implementa- tion of the following two-part mitigation measure would reduce the potential impacts of on- and off- site flooding to a less-than-significant level. Mitigation Measure HYDRO-2a: The project proponent shall provide flood control storage such that peak stormwater flow rates from the project do not exceed pre-project flow rates for,large storm events (the 10-year storm event up to and including the 100-year storm event); unless it can be conclusively shown in a detailed hydrology study that detention at the project site would not result in detrimental impacts on- or off-site in the vicinity of the project, due to phasing of peak flows in Grayson Creek. Required stormwater management infrastructure, including detention,will be described in a Drainage Study that shall use design guidelines and hydrograph methodology consistent with Contra Costa County standards. The hydrology and drainage plan for the proposed project shall be prepared by a qualified professional in accordance with Contra Costa County Public Works Department requirements. The report shall demonstrate that peak stormwater flow rates from the proposed project will not increase the potential for flooding on- or off-site. Mitigation Measure HYDRO-2b: Grading and drainage plans shall be reviewed for compliance with County requirements by the Contra Costa County Engineering Services Department. Any improvementsto the storm drain system deemed necessary by the County,including construc- tion of or improvements to stormwater conveyances, shall be part of the conditions of approval for the proposed project. Implementation of Mitigation Measures HYDRO-la and lb and HYDRO-2a-and 2b would reduce on- and off-site flooding due to alteration of the drainage pattern to a less-than-significant level. e) Create or contribute runoff water which would exceed the capacity of existing or planned stormwater drainage systems or provide substantial additional sources of polluted runoff? (Potentially Significant Unless Mitigation Incorporated) The increase in impervious surface area at the project site(noted in Section VIII.b.)would corres- pondingly increase runoff from the site. Peak discharge from the site, for the 10-year storm event, will increase to approximately 25 cubic feet per second(cfs). This is approximately a 6.4 cfs increase or 34 percent over the pre-project condition.24 However,the proposed project conforms to both the existing 24 Sellecci,2007.op.cit.

(Potentially Sign ificani Unless Mitigation Incorporated) The Federal Emergency Management'Agency(FEMA)Flood Insurance Rate Map (FIRM) for the project area25 shows that most of the project site lies within Zone C,which is not subject to 100-year flooding. There is a small area,less than one acre, along the northwestern edge that lies in Zone B which indicates that it is either between the limits of the 100-year and 500-year flood or subject to inundation of less than one foot in the 100-year flood. Parking lot facilities are planned for the portion of the project site that lies within Zone B. With proper design and installation of drainage features as called for in Mitigation Measures HYDRO-2a and HYDRO-2b,these facilities will not impede or redirect flood flows. i) Expose people Or structures to a significant risk of loss, injury or death involving flooding, including flooding of as a result of the failure of a levee or dam?

FEMA mapping does not indicate.any flood risk at the Airport from Walnut Creek;though neither the Flood Insurance Study nor the FIRM indicate base flood elevations for Walnut Creek. The Walnut Creek channel within the City of Concord(east of the Airport)has been improved by the United States Army Corps of Engineers(Corps)to contain the 100- year flood.27 The levees along Walnut Creek are maintained by the Corps..As such, exposure to risk involving flooding due to failure of a levee or dam would not be expected. j) Inundation by seiche, tsunami, or mudflow? (No Impact) No enclosed bodies of water,likely to be affected by seiches,are present in the project vicinity. Likewise,the project area and surroundings are relatively level.Thus,no inundation from mudflows would be expected. Due to its inland location, the project site is not likely subject to inundation by tsunami(a sea wave caused by earth movement). This is supported by the fact that the 1964 earthquake in the Gulf of Alaska caused a tsunami with waves that produced a run-up of 1.1 meters in San Francisco and 1.5 meters in San Rafael while at Benicia, the run-up diminished to 0.1 meters.28 A similar reduction is seen for the 1960 Chilean earthquake that caused a 0.9-meter run-up at San Francisco and a less than 0.1 meters run-up at Benicia.29 Benicia is approximately 30 river miles inland from the Golden Gate. Pacheco Slough joins Suisun Bay roughly two river miles upstream from the Benicia tidal gage. From Suisun Bay to the project site measures an additional four miles (up Pacheco Slough,Walnut, and Grayson Creeks and the drainage channels)with a gain of roughly 18 to 20 feet in elevation. Thus the project site lies roughly 36 river miles from the Golden Gate with the Carquinez Strait serving as.a natural buffer to reduce such sea waves. Mean higher high water(MHHW)at the.Port Chicago gage on Suisun Bay is 3.45 feet NGVD.30 The highest observed water level recorded at the gage is 6.46 feet NGVD on December 3, 1983.The project site minimum elevation is 18 feet NGVD,thus, given attenuation of the wave between the Golden Gate and Benicia,no inundation from tsunami would be expected. 27 Federal Emergency Management Agency,2001.Flood Insurance Study,City of Concord,California,revised September 7,2001. 2E Magoon,O.T., 1962.The tsunami of May 1960 as it affected Northern California,ASCE Hydraulics Division Conference,Davis,California. 29 Magoon,O.T., 1966.Structural Damage by Tsunamis,Proceedings,ASCE Specialty Conference on Coastal Engineering,Santa Barbara(California),Oct. 1965,35-68. 30 National Oceanic and Atmospheric Administration,2007.

(Potentially Significant Unless Mitigation Incorporated) The proposed vroject itself would not generate additional aircraft flights;however. existing flights from the Airport are an existing noise source in the area and flights from the Airport would increase over time. Additionally,the proposed project would include development of aviation and non-aviation land uses which could generate additional vehicle trips on roadways adjacent to the Airport. Noise impacts on the proposed project would be primarily from aircraft or aviation noise sources. Federal Aviation Regulation, Part 150, "Aviation Noise Compatibility Planning,"sets forth noise. compatibility guidelines for airport land use. These guidelines determine the acceptable or compatible P -48 LSA ASSOCIATES. INC. CCR HANGARS 1 LLC PROJECT AT BUCHANAN FIELD AIRPORT DECEMBER 2007 INITIAL STUDY/MITIGATED NEGATIVE DECLARATION level of maximum noise exposure for people in areas affected by Airport and aviation related noise sources. According to these guidelines, exposure to noise levels below 65 dBA CNEL would be considered acceptable or compatible for all types of land use. According to the Contra Costa County Airport Land Use Compatibility Plan,32 the normally acceptable noise levels for office space land use within 3 miles of Buchanan Field Airport is 60 dBA CNEL,marginally acceptable noise levels for commercial uses can range up to 70 dBA CNEL. According to Figure 3B of the Contra Costa County Airport Land Use Compatibility Plan,the proposed project site lies within the 65 dBA CNEL future noise contours for the Airport. Portions of the project site bordering the runway may be exposed to aircraft related noise levels of up to 70 dBA CNEL. These noise levels are considered acceptable for office development as long as interior noise standards are met and no exterior activity areas are planned as part of the project. The proposed project does not include any outdoor activity areas;therefore,implementation of the following mitigation measure would reduce aircraft related noise impacts to a less-than-significant level. Mitigation Measure N0I-1: To ensure that windows can remain closed for a prolonged period of time, an alternate form of ventilation, such as air conditioning, shall be required for all new office buildings within the project site. Such alternate form of ventilation shall not compromise the acoustical integrity of the building facades, and shall not create excessive interior noise levels due to its operation. This mitigation applies to all new office facilities,the new airport administrative building, and the new aviator's lounge/conference center located within the project site. Noise impacts on off-site sensitive receptors in the project vicinity would include aircraft or aviation noise sources and traffic noise sources due to project-related increased traffic volumes. The proposed project is expected to generate 226 additional daily trips to the surrounding roadways. This number of additional trips would not cause a significant increase in traffic noise to off-site receptors. Long term noise increase due to project related increased traffic volumes would be less-than-significant impact. The project would locate new facilities closer to noise sensitive receptors than current conditions. Parking lot and hangar facilities would be located within approximately 140 feet of existing residential land uses bordering Marsh Drive to the west. At this distance, noise levels from typical parking lot. activities would riot create a perceptible permanent increase in ambient noise levels for these sensitive receptors.In addition, the new facilities would aid in decreasing some of the aircraft related noise by acting as a sound barrier between the residential land uses bordering Marsh Drive and the aircraft runway and hangar activity noise sources.Buildings that block the line of sight between a noise source and a receiver can reduce noise levels by as much as 15 dBA. Therefore,noise from parking lot and aircraft-related activities at the hangars would result in a less-than-significant impact on noise sensitive receptors in the project vicinity. 32 Contra Costa County,2000.Contra Costa County Airport Land Use Compatibility Plan.December.

However,the County considerers this short-term impact to be less than significant if each of the noise-reducing measure, described below, is implemented. Implementation of the following mitigation measure would reduce the project's temporary construction-period noise impact to a less-than- significant level: Mitigation Measure NOI-2: All project construction contractors shall comply with the following noise reduction measures: • General construction noise shall be limited to weekdays from 7:00 a.m.to 6:00 p.m; however; construction activities may occur between the hours of 8:00-'a.m to 5:00 p.m. on weekends and federal and State holidays with the written authorization from the Director of Airports and/or once a particular structure is fully enclosed; • Pile driving(if required) and any other similarly loud activities shall be limited to weekdays from 8:00 a.m. to 5:00 p.m.; • .

The results show that the majority of the SENEL values over 65 dBA occurred between the hours of 7:00 a.m. and 11:00 a.m.,which coincides with typical peak hotirs for ambient peak community noise levels(i.e.,traffic,landscape equipment and delivery trucks). Airport planning efforts are currently evaluating options to reduce airport related noise to the extent feasible;however,project related noise would not create a substantial temporary or periodic increase in ambient noise levels in the project vicinity above existing levels without the project. e) For a project located within an airport land use plan or, where such a plan has not been adopted, within two miles of a public airport or public use ail port, would the project expose people residing or working in the project area to excessive noise levels?(Potentially Significant Unless Mitigation Incorporated) As discussed in Sections XI.a and XIA, above,with implementation of Mitigation Measures N0I-1, the project would not expose people residing or working in the area to excessive noise levels.With the implementation of the proposed project,noise levels would be within the regulatory guidelines of the various agencies goveming the project. J) Fora project within the vicinity of a private airstrip, would the project expose people residing or working in the project area to excessive noise levels? (Potentially Significant Unless Mitigation Incorporated) As discussed in Section XI.e, above, significant noise exposure is not expected due to any aircraft and aviation related noise sources associated with the project.

These services are generally provided by the Contra Costa County Fire Protection District(CCCFPD) and the Contra Costa County Sherriff's Department,respectively. However,Airport staff may also fulfill some of these functions. The Contra Costa County Sherriff's Department Field Operations Bureau provides patrol, investiga- tion,and administrative and community services to the unincorporated areas of the County, including the project site. Muir Sherriff Station is located in Martinez at 1980 Muir Road, less than 2 miles west of the Airport. County General Plan Policy 7-59 establishes a maximum response time goal for priority 1 or 2 calls of five minutes 90 percent of the time within central business districts and urban and suburban areas within the County,including the Airport. The CCCFPD provides fire and life safety services within the central and northern portions of County,' including the project site. Station 6 is nearest to the Airport,located less than 2 miles to the southeast at 2210 Willow Pass Road. General Plan Policy 7-63 establishes a total response time (including dispatch plus running and set-up time)of five minutes 90 percent of the time within the central business districts and urban and suburban areas within the County,including the Airport. In addition to CCCFPD services, on-site fire response is provided by Aircraft Rescue and Fire Fighting (ARFF)response vehicles located directly north of the existing Airport administrative offices along Sally Ride Drive. Because the proposed project would not result in an increase in operational capacity or population, no significant increase in demand for police and fire protection services would be expected.Nor would school or park space be adversely affected.The project would not result in substantial adverse physical impacts associated with the provision of new or physically altered governmental facilities or the need for new or physically altered governmental facilities. In addition, prior to issuance of individual P:(.'C(SI701�PRODIICfSVSMM�Fin'eRfnuBS('hecMJridoc(I II.sQ^00'T) 53 ...SA ASSOCIATES. INC. CCR HANGARS I LLC PROJECT AT BUCHANAN FIELD AIRPORT DECEMBER 2007 INITIAL STUDY/MITIGATED NEGATIVE DECLARATION building permits,the County Sherriff and CCCFPD would have the opportunity to review project design plans and provide input to ensure that the proposed project complies with site design safety standards. For all of these reasons, development of the proposed project would not result in substantial adverse physical impacts to.public services.

TRANSPORTATION/TRAFFIC.Would the project: . a) Cause an increase in traffic which is substantial in relation to the existing traffic load and capacity of the street system (i.e.,result in a substantial increase in either the number of vehicle trips,the volume to capacity ratio on roads,or congestion at intersections)? b) Exceed,either individually or cumulatively,a level of service standard established by the county congestion management agency or designated roads or highways? c).Result in a change in air traffic patterns,including either B an increase in traffic levels or a change in location that results in substantial safety risks? d) Substantially increase hazards due to a design feature A (e.g.,sharp curves or dangerous intersections)or incompatible uses(e.g.,farm equipment)? e) Result in inadequate emergency access? f) Result in inadequate.parking capacity? g) Conflict with adopted polices,plans,or programs supporting alternative transportation(e.g.,bus turnouts, bicycle racks)? a) Cause an increase in traffic which is substantial in relation to the existing traffic load and capacity of the street system (i.e., result in a substantial increase in either the number of vehicle trips, the volume to capacity ratio on roads, or congestion at intersections)? (Less-Than- Signifzcant Impact) The project site is currently used for the storage of 31 airplanes.The proposed project would construct 43 airplane hangers and an administrative building of up to 20,000 square feet. Several of the airplane hangers would also include the development of attached office bungalows. These office bungalows would include attached two-car garages and serve the office needs of airplane hangar tenants. Office bungalows could include a bathroom/shower, flight planning room,media room,pilot lounge,office space and/or a rest area. The office bungalows would be associated with the airplane hangar and therefore, for.trip generation purposes office bungalows were not considered independent trip gener- ators. The administrative office building would be designed with up to 20,000 total square feet of space.This building would include a community meeting space, airport administration office space for up to 20 employees, storage space and airplane hangars. Trip generation estimates are included in Table 3 and were calculated based on the 7th Edition,ITE Trip Generation Handbook.

The Contra Costa Transportation Authority Growth Management Program requires a detailed traffic impact analysis for projects that generate 100 or more peak hour trips. The proposed project would generate a net of 15 peak hour trips;therefore a detailed analysis is not required. The increase in trips associated with the proposed project would not represent a substantial increase in traffic to the roadways surrounding the project site. b) Exceed, either individually or cumulatively, a level of service standard established by the county congestion management agency or designated roads or highways? (Less-Than-Significant bttpact) The project would not result in a significant increase in traffic volumes and therefore would not exceed level of service standards established by the County. See Section Wa. c) Result in a change in air traffic patterns, including either an increase in traffic levels Or a change in location that results in substantial safer?risks? (Less-Than-Significant Impact) The proposed project would provide hangar and office space. A substantial increase-in air traffic is not anticipated and any increase in air traffic could be accommodated by the Airport.No adverse change in safety risks would be expected. d) Substantially increase hazards due to a design feature(e.g., sharp curves or dangerous intersections) or incompatible uses (e.g.,farm equipment)? (Less-Than-Significant Iinpact) Vehicular access to the project site would be provided by new driveways connecting to Center Avenue on the south and Sally Ride'Drive on the north. A private roadway would run the length of the western border of the site,parallel to Marsh Drive. This roadway would provide access to surface parking spaces located in front of the hangar areas. Project driveways have all been designed as standard full- access driveways. Parking on-site is generally in 90-degree stalls with two-way drive aisles.No dead- pv"C(?7r.t�r'R:JU!�1'S�ISMI+T�Fiut'•FimIIS:;nsklis.dx li li3�b'^'-IM'>I 56 LSA ASSOCIATES. INC. CCR HANGARS I LLC PROJECT AT BUC14ANAN FIELD AIRPORT DECEMBER 1007 INITIAL STUDY/MITIGATED NEGATIVE DECLARATION end parking aisles are proposed, and the planned circulation is adequate to accommodate the anticipated land uses. Therefore,the project would not increase hazards due to a design feature. e) Result in inadequate emergency access?(Less-Than-Significant Impact) Vehicular access to the project site would be provided by new driveways connecting to Center Avenue on the south and Sally Ride Drive on the north. These driveways would provide sufficient emergency access. Result in inadequate parking capacity? (Less-Than-Significant Impact) The proposed project would provide a total of 160 parking spaces. The project would provide 88 surface parking spaces along the perimeter of.the hangar area and 24 parking spaces within the two-car attached garages. The provided surface parking and garage parking would meet parking demand for the proposed hangars. A total of 48 surface parking spaces would be provided for the administration building. The Airport has historically required 1 parking space for each aircraft hangar and 1 space per 250 square feet of aviation oriented office space. The total building space associated with the proposed administration building would be 20,000 square feet. However,this space would include airplane hangars, storage space, a community meeting room and office space for up to 20 employees.As shown in Table 3, based on the number of employees that would work at the office,the office would not generate an extensive amount of traffic. The proposed 48 surface parking spaces would be adequate to meet the parking demand for the number of employees the office space would accommodate.Therefore,the proposed project would not result in inadequate parking capacity. g) Conflict with adopted polices,plans, or programs supporting alternative transportation (e.g., bus turnouts, bicycle racks)?(Less-Than-SignifcantImpact) The nearest fixed rail alternative transportation to the site is provided by Bay Area Rapid Transit (BART),which has stations in both downtown Concord and North Concord,both of which are located about 4 miles from the Airport. Local public transportation in the Concord area is provided by County Connection,which pro-zdes fixed-route bus and paratransit service throughout the central Contra Costa communities of Clayton, Concord,Martinez, Pleasant Hill, Walnut Creek, Danville, San Ramon, Lafayette,Orinda, and Moraga, as well as unincorporated communities. The proposed project,which would not affect existing transit,pedestrian, or bike access, would not conflict with policies,plans,or other programs supporting alternative transportation.

UTILITIES AND SERVICE SYSTEMS.Would the prof ect: a) Exceed wastewater treatment requirements of the applicable Regional Water Quality Control Board? b) Require or result in the construction of new water or C3 13 wastewater treatment facilities or expansion of existing facilities,the construction ofwhich could cause significant environmental effects? c) Require or result in the construction of new storm water drainage facilities or expansion of existing facilities,the construction of which could cause significant environmental effects? d) Have sufficient water supplies available to serve the project from existing entitlements.and resources,or are new or expanded entitlements needed? e) Result in a determination by the wastewater treatment provider which serves or may.serve the project that it has adequate capacity to serve the project's projected demand in addition to the provider's existing commitments? f) Be served by a landfill with sufficient permitted capacity ® 0 to accommodate the project's solid waste disposal needs? g) Comply with federal, State,and local statutes and 0 regulations related to solid waste? a) Exceed wastewater treatment reguirements•of the applicable Regional Tfrater Quality Control Board? (Less-Thad-Significant Impact) The proposed project,would include the construction of hangar/office bungalows and an Airport administration building. Contra Costa County Sanitation District(CCCSD) owns and operates the Wastewater Treatment Plant(WWTP)in Martinez. The Treatment Plant has a wet weather design capacity of 240 million gallons per day(mad) and a dry weather design capacity of 55 mad. The averaae effluent discharae from the WWTP is currently limited to 53.8 mad by Water Board NPDES permits. The average daily dry weather flow in 2004(the most recent year information is available) was 39.9 mad. Wastewater conveyance to the WWTP would be served by existing main lines. Development of the proposed project would not generate significant amounts of wastewater, and small increases in wastewater generation could be accommodated by the existing capacity of the WWTP.

CCA HANGARS I LLC PROJECT AT BUCHANAN FIELD AIRPORT .DECEMBER 1007 INITIAL STUDY/MITIGATED NEGATIVE DECLARATION' Therefore, development of the proposed project would not exceed the wastewater treatment requirements of the Water Board. An existing 8-inch sanitary sewer line is located at the northern boundary of the site. The proposed project would properly abandon a section of this line and connect to the existing line with a reconfigured 8-inch line located beneath the parking areas at the northern section of the site. Existing sanitary sewer lines are anticipated to have sufficient capacity to accommodate the proposed project. b) Require or result in the construction of new water or wastewater treatment facilities or expansion of existing facilities, the construction of which could cause significant environmental effects? (Less-Than-Significant Impact) The project site is located in Contra Costa Water District's (CCWD)Treated Water Service Area. CCWD operates two water treatment plants within its water supply and distribution system: the Robert D. Bollman Water Treatment Plant and the Randall-Bold Water Treatment Plant(co-owned by the Diablo Water District). CCWD's overall daily treatment capacity is 100 mad. Development of the proposed project would not significantly increase water demand at the Airport.No new major water treatment facilities would be required to serve the proposed project. A 12-inch water line currently runs from approximately the southeastern section of the site to approximately the northwestern comer of the site. The Contra Costa Water District(CCWD)would properly abandon a section of this water line. An 8-inch water line is also located along the northern boundary of the site. CCWD would construct a new 12-inch water line beneath the private roadway at the western section of the site. This new water line would connect to the existing water lines beneath Taxiway E and at the northwest comer of the site. The project proponent would be responsible for financing of the modifications to the water distribution system serving the proposed project. Existing water lines are anticipated to have sufficient capacity to serve the proposed project. Please refer to Section XVI.a for a discussion of impacts to wastewater treatment facilities. c) Require or result in the construction of new storm water drainage facilities or expansion of existing facilities, the construction of which could cause significant environmental effects? (Potentially Significant Unless Mitigation:Incorporated) Development of the proposed project would alter the existing drainage pattern on the site,requiring the construction of new storm drain facilities,which would in turn result in adverse environmental effects. However,implementation.of Mitigation Measures HYDRO-1 a,HYDRO 1b,HYDRO-2a and HYDRO-2b would reduce this impact to a less-than-significant level. Please refer to Section VIII.d for a detailed discussion of the proposed alteration of the existing drainage pattern and proposed storm . drainaae facilities. d) Have sufficient water supplies available to serve the project from existing entitlements and . resources, or are new or expanded entitlements needed? (Less-Than Significant Impact) The Contra Costa Water District(CCWD)`supplies water to the Airport. CCWD receives a maximum . delivery of 195,000 acre-feet per year from the Central Valley Project(CVP),with a reduction in deliveries during times of water shortages, such as drought years.

(Less-Than-Sig nifcant Impact) Please see Section XVI.a. _0 Be served by a landfill with sufficient pernsitted capacity to accommodate the project's solid waste disposal needs? (Less-Than-Significant Impact) Franchised solid waste collection, disposal,and recycling services for the Airport are provided by Pleasant Hill Bayshore Disposal. Airport waste is hauled to any one of the three landfills located within the County or to.landfills located outside of the County. Solid waste generated by the proposed project would include construction and demolition waste due to the removal of existing structures and pavements. Operational waste would also be generated by the proposed project. However,the proposed project would not generate a significant amount of solid waste,such that the permitted capacity of any receiving landfills would be significantly adversely affected. Airport waste oil is collected and recycled by Clear Water.Businesses and individuals dispose of hazardous waste generated at their facilities to the nearest.solid waste facility that accepts such products. The proposed project would not increase Airport-wide hazardous waste generation or substantially reduce the capacity of receiving hazardous waste facilities. g) Comply with federal, State, and local statutes and regulations related to solid waste? (No Impact) The proposed project would comply with all federal, State, and local solid waste statutes and/or regulations related to solid waste. sa Contra Costa Water District,2007.Water Quality—The Source of Your Water.Website:wky.ccwater.com.

(Less-Tlzaiz-Siaizifzcazzt Impact). Other planned and anticipated projects within the vicinity of the project site are included in Table 4. These foreseeable projects could be expected to result in minimal adverse environmental impacts, similar to the development of the proposed project. These impacts could include incremental increases in stormwater runoff, minor disturbances to wildlife, and other effects typical of projects undertaken in already-developed areas. With the mitigation measures recommended in this report,the impacts of the proposed project are individually limited and not cumulatively considerable in the context of impacts associated with other pending or planned projects. Development of the proposed project and other projects on Airport property would result in additional aviation and non-aviation-related development, consistent with existing uses at the Airport. All environmental impacts that could occur as a result of the proposed project would be reduced to a less-than-significant level through implementation of the mitigation measures recommended in this IS/MND.

PACCC070 d.(11130.^1X17) 64 MITIGATION MONITORING AND REPORTING PROGRAM This Mitigation Monitoring and Reporting Program(NUVIRP)was formulated based on the findings of the Initial Study/Mitigated Negative Declaration(IS/MND)prepared for the CCR Hangars I LLC Project at Buchanan Field Airport.This MMRP is in compliance with Section 15047 of the CLOA Guidelines,which requires that the Lead Agency"adopt a program for monitoring or reporting on the revisions which it has required in the project and the measures it bas imposed to.mitigate or avoid significant environmental effects."Tile MM-RP lists mitigation measures recommended in the IS/NC\TD and identifies mitigation monitoring requirements. These requirements.are provided only for mitigation measures that would.reduce or avoid significant impacts of the proposed project. Table 1 presents the mitigation measures identified for the proposed project. Each mitigation measure is numbered according to the topical section to which it pertains in the ISIMND..As an example, Mitigation Measure AIR-1 is the first mitigation measure identified in the ISUND. The column entitled"Mitigation Responsibility"identifies the party responsible for carrying out the required actions.The columns entitled"Monitoring/Reporting Agency and"Monitoring Schedule" identify the party ultimately responsible for ensuring that the mitigation measure is implemented and the approximate timeframe for the oversight agency to ensure implementation of the mitigation measure.The column entitled"Verification of Compliance"will be used by the lead agency to document the person who verified the implementation of the mitigation measure and the date on which this verification occurred.

This Phase II ESA was performed in general conformance with the scope of work presented in our Proposals PP2681,dated August 8,2007(revised November 1,2007), and PP 2721, dated November 26, 2007 (revised December 7, 2007). The property consists of approximately 13.97 acres of airport property owned by the County of Contra Costa. This property includes three main buildings,including the Mount Diablo Pilot's Association clubhouse structure located at 200 Sally Ride Drive, the Metal Air Flight Services building at 180 Buchanan Field Road and the Concord Flying Club building at 266 Buchanan Field Road. The remaining portions of the site consist of an open field (represents most of the western portion of site) or are paved with concrete and asphalt. Several environmental concerns were identified by the author of the site Phase I ESA (ERM.S, 2007) that required further assessment prior to site development. These included a former military refueling pit/revetment located behind the Mount Diablo Pilot Association's clubhouse that was reportedly connected by piping to a former offsite Underground Fuel Storage Tank(UST), a UST previously removed from the Mount Diablo Pilot Association's clubhouse property,oil staining on the asphalt floors under airplanes and next to oil cans,possible use of pesticides in the open field located along the west side of the site,potential asbestos and lead containing building materials in the existing buildings and possible leakage of toxic material that may have been placed in the septic tank at the Concord Flying Club building. SCOPE OF SERVICES Our scope of work for this.Phase 11 ESA consistedof the following tasks: Consult with Buchanan Airport officials to obtain and review any available information documenting the location of the former on-site or associated off-site USTs and on-site aviation piping identified in the referenced report. Hayward San Luis Obispo Pleasant Hill No. 03-360/7372-01 March 6, 2008 Page 2 • Prepare a site specific Health and Safety (H&S) Plan. • Perform site evaluation to locate reported underground piping using high powered, multi-frequency Radio Detection transmitter/receiver or ground penetration radar. Also, perform site evaluation with electronic survey equipment to locate any potential buried structures around MDPA building. • Drill. and log up to 15 exploratory borings to depths of up to approximately 20 feet to obtain representative soil and groundwater samples for laboratory analysis and to observe subsurface conditions. Five hand-augered soil samples would be obtained at the reported oil stained floor surfaces. A Geoprobe type drill rig was used to perform the subsurface exploration. Four baseline borings were advanced near the property corners for indications of off-site environmental impact to the subject site. The baseline borings would also assist in evaluating possible sources of any contamination found in the site specific borings. Samples were labeled with the project name, time and date, placed in a sealed bag and stored on ice in a cooler for subsequent transport under chain-of-custody protocol to McCampbell Analytical, Inc., a California Department of Health Services (DHS) certified hazardous waste laboratory. • Select soil and groundwater samples were analyzed for the following constituents: TPH gas, diesel, and kerosene using EPA Method 8015 MTBE/BTEX using EPA Method 8260 Oil and grease using EPA Method 5520 Chlorinated Solvents using EPA Method 8260 CAM 17 Metals using EPA Method 6010/6020 • Deliver groundwater samples. under chain-of-custody procedures to a State-certified analytical laboratory to be analyzed for the following constituents: TPH gas, diesel, and kerosene using EPA Method 8015 MTBE/BTEX using EPA Method 8260 Chlorinated Solvents using EPA Method 5520 CAM 17 Metals using EPA Method 6010/6020 Pesticides Because the referenced Phase I ESA indicated that the subject site may have been used for agriculture purposes, chlorinated pesticides may have been applied to control insects. Contra Costa County Hazardous Materials Department(CCCHMD)provides guidelines for sampling and testing former farmland for chlorinated pesticides, arsenic and lead in the Cities of Oakley and Brentwood but not in County jurisdiction (personnel communication, Ms. Dena Hutchins CCCHMD). Our sampling and laboratory testing generally followed their guidelines with sampling limited to the approximately 7 acres of field area. Seven soil samples were analyzed for the presence of organochlorine pesticides (including DDT), arsenic and lead. Purcell,Rhoades &Associates No. 03-360/7372-01 March 6, 2008 Page 3 Asbestos and Lead Containing Building Materials The referenced Phase I ESA report stated that due to the age of the existing site buildings, both asbestos and lead containing building materials may have been used during construction of the existing structures. PRA subcontracted with Environmental Resource Group, Inc.(ERG),of Mill Valley to perform the asbestos and lead surveys for the site buildings. The environmental hazards that the surveys addressed were Asbestos- Containing Building Materials (ACM's) and Lead Paint. The Scope of Work was as follows: 1. Identify by visual inspection, suspect ACM's such as: wall and ceiling materials, duct.wrap, and pipe wrap; resilient floor coverings,thermal system insulation (TSI); and any other suspect areas containing ACM's. 2. Collect bulk samples of suspect building materials that have a potential for containing asbestos from homogeneous areas,using a random,non-destructive sampling plan,which complies with Federal and State regulatory agencies. 3. Assess the physical condition of each potential ACM. 4. Provided a written report of the surveyed buildings which contains the following: Description of surveyed building(s); . Description of laboratory testing and results of ACM testing; Description of locations, quantities and conditions of identified ACM's; Recommendations based on visual inspections and laboratory test results. STUDY Buchanan Airport Records Review, Electronic Surveying& Consultation Prior to initiation of the subsurface exploration, a representative of this office consulted with Ms.Julie Conti of the Real Estate Division of Buchanan Airfield to attempt to locate any additional 'information or records regarding the historical construction of underground fueling equipment such as USTs, piping and the refueling pWrevetment and the removal of the UST from behind the MDPA building. Although no information was available regarding refueling equipment or the removal of the UST from behind the MDPA building, a map prepared by the military was located and provided to us for our review. This map provided the location of the storm drain system installed by the military that is currently still in use. Shown on this plan is the catch basin located immediately behind the MDPA building, the buried piping that discharges to the north, parallel to the rear of the structure and into a buried manhole located near the northeast corner of the structure. The pipe is then shown running to the west and.discharging into the field on the west side of the existing asphalt parking lot;however,at some point.in time,this pipe was connected to the Airfields storm'drain system as it apparently no longer discharges into the field. The location of the storm drain system was confirmed by electronic surveying performed by ForeSite as a part of this study. As mentioned, an electronic survey of portions of the site was performed to locate buried refueling equipment and a UST. Although the UST had been reportedly removed from the site, some of the MDPA club members Purcell,Rhoades&Associates No. 03-360/7372-01 March 6, 2008 Page 4 of the MDPA reported that the UST had not been removed and others had reported that there may have been a 30,000 gallon UST remaining at the site. It had also been reported that about 500 gallons of gasoline from the UST removed behind the MDPA building had been discharged into a drywell located behind the MDPA building. Based on these reports,we retained the services of ForeSite,a consultant that specializes in locating buried structures using various types of remote sensing equipment. His scope of work included scans of the entire rear area of the MDPA building to search for indications of the 500 gallon and 30,000 gallon USTs,buried refueling lines and storm drain lines(the storm drain line search continued to the west(front)of the building and into the open field where the storm drain line had originally discharged for the purpose of locating a boring at . that position for soil and groundwater sampling). ForeSite also found indications of a buried concrete structure running east to west behind the MDPA building as well as wiring that provided power to the pump island used to pump fuel from the 500 gallon UST. A copy of the ForeSite report is included in Appendix A. Boring Locations Borings B-1 and B-2 were located along the underground fuel lines that run from the north end of the property to the refueling pit/revetment located behind the MDPA building. The location,depth to the pipes and alignment of these buried fuel lines was performed by ForeSite using electronic remote sensing equipment. Only soil samples were obtained in these two borings. Borings B-3, B-4 and B-5 were also located behind the MDPA building. The locations of these borings were based on the findings of the project Phase I ESA and information regarding other potential Underground Fuel Storage tanks(UST) that was provided to us by MDPA members. Boring B-6 was located adjacent to the refueling pit/revetment. An archived military site pian provided to our office during preparation of this report provided data regarding the location of the existing, buried storm drain pipe adjacent to the.MDPA building. Environmental Drilling and Soil Sampling The borings were advanced using a truck mounted Geoprobe. Soil samples were collected using a 2-inch I.D. sampler driven 48 inches by a vibrating hydraulic ram. Soil removed from the top 42 inches of the plastic sample tube and the end cone were used for visual logging purposes and disposed. Soil from the bottom 6 inches of plastic tube was saved for laboratory analysis. Soil samples from each sampling interval were lithologically described by a PRA geologist in accordance with the Unified Soil Classification System. Grab groundwater samples were.obtained using disposable bailers with the water placed in clean 1 liter amber bottles and VOAs. The soil and groundwater samples were.visually observed in the field. The plastic tubes used to collect the soil samples were sealed using plastic end caps. The soil samples were labeled with the project name, time and date, placed in a bag and stored on ice for subsequent transport under chain-of-custody protocol to McCampbell Analytical, Inc. The groundwater samples were labeled with the project name,time and date and stored on ice for subsequent transport under chain-of-custody protocol to a California DHS certified hazardous waste laboratory. All drilling activities were supervised by PRA's geologist. The soil borings were backfilled with portland cement. All sampling equipment was thoroughly.scrubbed with an Alconox solution and rinsed with distilled water prior to beginning of sampling and between all samplings. A detailed PRA's Soil Sampling Protocol is presented in Appendix B. Purcell,Rhoades &Associates No. 03-36017372-01 March 6, 2008 Page 5 Mapping by ForeSite indicated that the storm drain catch basin located behind MDPA discharged into a pipe that ran to stormdrain manhole at the. northeast corner of their building. From the manhole, the stormdrain turned to the west and discharged near the location of Boring B-12. Therefore, we placed Boring B-10 at the manhole and B-12 at the discharge point to obtain soil and groundwater samples for laboratory testing. Borings B-7, B-8 and B-9 were located under the graveled and paved areas behind the MDPA building. Borings B-11, B-13 and B-15 were drilled at the corners of the property for soil and groundwater baseline data (Boring B-8 was also used for obtaining baseline data). Boring B-14 was drilled adjacent to the former septic tank location at the Concord Flying Club (CFC) hangar.

Volatile Organics The second set of laboratory tests was for Volatile Organics using EPA Test Method SW8260B. For the soil samples,all samples had Non-Detect levels of the Volatile Organic chemicals tested for except for Sample B47 S2, where ethyibenzene was detected at a concentration of 0.012 part per million. For the water samples, all samples had Non-Detect levels of the Volatile Organic chemicals tested except for Sample B4-W 1-W4,where Purcell,Rhoades&Associates No. 03-360/7372-01 March 6, 2008 Page 7 the following chemicals were detected: Acetone 20 parts per billion (ppb); ethylbenzene - 5.2 ppb; isopropylbenzene - 1.9 ppb; naphthalene - 0.74 ppb; and, n-Propyl benzene - 3.1 ppb.

Five hand-augered borings were made at select oil-stained asphalt floor locations to obtain soil samples for laboratory testing- The soil samples were tested for the presence of Petroleum Oil and Grease using EPA Test Method SM5520 E/F and Volatile Organics using EPA Test Method SW5030B. The test locations are indicated on Figure 2 as"TH"as an abbreviation for`Test Hole"and the soil samples are indicated on the laboratory test sheets as"OS-1"through "OS-5." All test holes were pre-cored to remove the overlying asphalt and gravel sub base material,if present. TH-6 encountered approximately 10 inches of concrete during coring when it was decided to terminate this test hole because of the very low potential for any significant seepage of spilled fluids through concrete of such thickness. Of the five soil samples tested for the presence of Petroleum Oil&Grease,only Sample OS-5 had a detectable test result of 84 ppm. Acetone, at 0.26 ppm in Sample OS-1, was the only detectable chemical constituent found of the target list of Volatile Organics tested in all five.soil samples. Copies of the COC along with the analytical results are included in Appendix D. Purcell,Rhoades &Associates No. 03-360/7372-01 March 6, 2008 Page 10 Organochlorine Pesticides Soil Sampiing For the organochlorine pesticides soil sampling program, we obtained four soil samples per acre from the property from 0 to 1 foot in depth. These samples were submitted to the laboratory for the testing described below. Sampling was accomplished by using a hand augering device and collecting the soil samples in zippable plastic bags at each sampling point. The soil samples were labeled with the project name, date and location and stored on ice in a cooler for subsequent transport under chain-of-custody protocol to the laboratory_ Every four samples were composited into one sample at the laboratory for testing. Seven soil samples were analyzed for the presence of organochlorine pesticides (including DDT), arsenic and lead. Chemical Analysis All samples were submitted to McCampbell Analytical, Inc., in Pittsburg, California for testing of the following compounds: • Organchlorine pesticides using EPA Method SW8081 B • Arsenic using EPA Method 7060 • Lead using EPA Method 6010C All samples submitted to the laboratory were delivered under chain-of-custody(COC) protocol. Copies of the COC along with the analytical results are included in Appendix E. .Results of the laboratory tests-for presence of arsenic and lead are summarized in Table III. It must be noted that the test results given below are presented as the worst case scenario,(i.e., actual lab result x 4) because of the dilution factor that is possible when compositing four soil samples into.one.

The assumption that groundwater is not a current or potable source of drinking water should be approved by the overseeing regulatory agency. TPH as gas in soil Sample 1310-S2 (Boring B-10 was located at the buried manhole at the northeast corner of the MDPA building)was 1000 ppm,which exceeds the ESLs (83 ppm &450 ppm', Tables A& B, respectively, SFRWQCB) for soil. ESLs for TPH'as gas in groundwater were exceeded in Samples B4-WI-W4 and B10- W 1-W4 (1600 ppb&410 ppb; Table A, ESL= 100 ppb and Table B, ESL=5,000,ppb, SFRWQCB). The test results for diesel and kerosene in soil Sample 1310-S2 were 1500 ppm.and 2300 ppm, which exceed the ESLs (83 ppm & 450 ppm). None of the diesel test results in the groundwater exceeded the ESLs except Sample B10-W1-W4 (260 ppb, ESL = 100 ppb, Table A, SFRWQCB). Oil and grease was found to be 64 ppm in Sample B4-S2. .Generally, diesel, kerosene and oil and grease contamination do not require remediation at these levels. The highest concentration levels of oil and grease were found to range from ND to 64 ppm in Sample B4-S2 and 69 ppm in Sample B7-S1. Borings B-4 and B-10 were located at the former UST behind the MDPA building and at the buried manhole located at the northeast comer of the building. The elevated concentrations of hydrocarbons at Boring B-10 suggest that fuel may have been discharged into the storm drain system and ponded at the bottom trap portion of the manhole. Eventual leakage of this fuel contaminated the underlying soil and groundwater. Boring B-11 was located near the southeast property line and was intended as a baseline boring. The positive test results of TPH diesel and TPH kerosene ih Boring B-11 suggest either impact of the soil by off-site sources or on-site contamination. None of the other soil or groundwater samples tested exceeded the ESLs. The results found in Borings B-4 and B-10 should be reviewed by the San Francisco Bay Regional Water Quality Control Board for determination of further study or remediation. For the Volatile Organics in the soil samples obtained in the borings, only ethylbenzene at 0.012 ppm was detected (in Sample B4-S2). The ESL for ethylbenzene is 33 ppm for soil; As discussed above, all groundwater samples had Non-Detect levels of the Volatile Organic chemicals tested for except for Sample B4- W 1-W4 where the following chemicals were detected: Acetone -20 parts per billion (ppb); ethylbenzene - 5.2 ppb;isopropyibenzene-1.9 ppb;naphthalene-0.74 ppb;and,n-Propyl benzene-3.1 ppb. The ESLs for these chemicals are as follows: acetone - 50,000 ppb; ethylbenzene - 300 ppb; isopropylbenzene - not listed; naphthalene - 210 ppb; and, n-Propylbenzene - not listed. Of the listed chemicals, none of the test results exceed the ESLs. No further testing or remediation is required for Volatile Organics in the soil or groundwater. Thirteen groundwater samples obtained from the borings were tested for the presence of CAM 17 metals. The ESLs for groundwater is 50,000 ppb for all 17 metals. None of the groundwater test results exceeded their respective ESLs in Table II-ESL B. However, several were exceeded if the results are compared to the SFRWQCB Table A ESLs(GW IS current or potential source of drinking water). Twenty-nine soil samples were obtained from the borings for testing for the presence of CAM 17 metals. The ESLs for chromium is 58 ppm and is based on SFRW QCB's review of a 2002 report prepared by the Lawrence Livermore National Laboratory Purcell,Rhoades&Associates No. 03-360/7372-01 March 6, 2008 Page 12 that found that typical background concentration of total chromium at a Bay property soils ranged from 1.7 ppm to 144 ppm with an arithmetic mean of 58 ppm. This was considered typical -for the Bay area in general. Therefore,this arithmetic mean concentration of 58 ppm was selected as a screening level for a total chromium in soil. The laboratory test results for antimony, selenium silver and thallium were non-detect. The test results for arsenic ranged.from 2.0 to 15 ppm. It is noted that the ESL for arsenic applies,to concentrations that are a product of human activities; and that natural background levels of arsenic are commonly well in excess of the listed screening level. According to Ms. Dena Hutchins of the Contra Costa County Hazardous Materials Department,the background level of arsenic in Contra Costa County is 6 to 12 ppm. It must be noted that in the screening level for arsenic, it applies to concentrations that are a product of human activities, and that it is noted that natural background levels of arsenic are commonly well in excess of the listed screening level. Of the 29 samples tested, only one sample (B4-S2, 15 ppm) exceeded the 12 ppm limit set forth by the Contra Costa County Hazardous Materials Department. None of the samples tested for.barium, beryllium, cadmium, cobalt, copper, lead, mercury, molybdenum, nickel, selenium, silver, thallium, vanadium or zinc met or exceeded their respective ESLs, as presented in Table II-ESL B, above. No further testing or remediation is required due to the results of the CAM 17 testing. When compared to Table II-ESL A(see above) the ESL for arsenic (1.5 ppm) is exceeded in all samples but is most likely due to the natural background levels of this element. None of the remaining ESLs for soils in Table II-ESL A were exceeded. For groundwater, several test results exceeded the ESLs presented in Table II-ESL A. Once again,there findings appearto be the result of natural occurring background levels of these metals. Most of the test results where the ESLs in Table II-ESL A were exceeded were from the groundwater sample obtained in B-15. Boring B-14 was drilled at the Concord Flying Club site to evaluate the potential for possible leakage of toxic material that may have been placed in the septic tank at the Concord Flying Club building. The referenced Phase I ESA had indicated that toxic.materials may have been placed in a sewer holding tank next to the clubhouse and that the soil underlying the tank should be tested for toxics. We learned through a discussion with Manly Ornsby of Clearwater Supply,the contractor that installed the new sewer system at the CFC building and from an interview with Mr. Les Miyashiro,an Environmental Health Specialist with the Contra Costa County Environmental Health Department,that a new septic tank and leach field were installed at the northwest corner of the CFC building approximately two years ago. A representative of this office met at the site with Mr.Ornsby. at the site to observe the area of the septic tank and leach field. Mr.Ornsby,who is also a member of the CFC, showed us where the.former septic tank once existed. A copy of the Contra Costa County Environmental Health Department Septic Permit dated July 7, 2005, was obtained from the CCCEHD (see Appendix G). A site plan provided with that permit indicated the location of the tank and leach field. Boring B-14 was located adjacent to the former septic tank site which was also downgradient from the new septic tank. This boring location would be expected to pick up any contamination from both the former septic tank location and the new tank location. The test results indicated an ND level of hydrocarbons and volatile organics for the soil and groundwater samples from Boring B-14. When compared to Table II-ESL A of this report,only the test results for chromium (69 ppb)and vanadium (94 ppb) exceeded the ESLs in Table A for groundwater. The only test result for soil to exceed the ESL in Table I I-ESL A was arsenic(Sample B14-S1,4.5 ppm and B14-S2,4.8 ppm) ESL = 1.5 ppm). All detected CAM 17 metals were below the ESLs when compared to Table II ESL-B. Of the five soil samples obtained at the oil stained surfaces and tested for the presence of Petroleum Oil & Grease, Sample OS-5 was found to beat 84 ppm which does not exceed the ESL of 2500 ppm. The test result Purcell,Rhoades &Associates No. 03-360/7372-01 March 6, 2008 Page 13 for Volatile Organics found acetone at 0.26 ppm in Sample OS-1. The ESL for acetone.in soil is 170 ppm. No further testing or remediation is required at the oil stained surfaces. The organochlorine pesticide test results indicated ND for all samples. We have compared the organochlorine pesticide test results with the Environmental Screening Levels(ESLs)for soils that are less than 3 meters below the ground surface for commercial/industrial sites as presented in the San Francisco Regional Water Quality Control Board Table B-2 (November 2007). In some cases, significant dilution factors were incorporated into the testing procedure for organochlorine pesticides because of the high organic content of the soil samples. These dilution factors were applied by the lab to the test results, which are presented as a concentration, i.e., ppm or ppb. This is evident in the test results presented for Samples S6 and S7 where dilution factors of 200 and 100, respectively, were included in the test results. Although the test results for all organochlorine pesticides were non-detect, the accuracy of the ND results are limited by the dilution factor. In some cases, the accuracy of the test results exceeded the ESLs; however,it should be noted that where a dilution factor was not added to a sample, such as Sample S5, all test results were ND. In preparation of this Phase II ESA, we subcontracted with Environmental Resource Group of Mill Valley to perform an Asbestos and Lead Survey of the three main structures at the site. A copy of their study is included in Appendix F of this report. Both asbestos containing building materials and lead surface coatings or materials were found in the structures. The overall condition of the buildings was reported as Good with only a small amount of physical damage to some of the construction materials. Environmental Resource Group recommends that all asbestos containing and lead containing construction materials, as listed in their report that will be disturbed during renovation/demolition activities, will have to be conducted by a Certified Contractor for asbestos and lead.

Attached is a plan showing approximate location of findings. On November 16'',2007, a visit to the above project was made to ascertain purpose of vent pipe east of the Mt.Diablo Pilots Assoc. Building. This was assumed to be the approximate location of a former underground storage tank(UST)as witnessed by local employee information. Access was provided by Julie Conti from the Real Estate division of the Airport. At the time of this visit light airplanes were obstructing a complete scan of the area. However,a scan using reflective induction(RI)was performed around the MDPA building and eastwards to the fuel pit. Anomalies were painted on the ground. Using electromagaetk field detection(EMF)a signal was generated onto the vent pipe and adjacent electrical conduits. The vent pipe carried virtually no signal suggesting either a very short distance or termination at that point. The electrical conduits were determined to travel southwards towards a cement base which we believed to be the former pump island and thence westward to endpoint before a cut off. This was probably the electric feed to the pump from the south corner of the MDPA building. Of particular interest was a steel plated pit which we were able to determine was an underground fuel hydrant with existing connection to a 3" or 4" steel pipe that continued northward off the parcel of concern. A further visit was made on November 21',2007. This enabled a complete trace out of the existing fuel line to a location off the parcel of concern. On this occasion we also performed a ground penetrating radar(GPR)scan,which revealed no typical UST signatures in the area around the vent pipe..However.structures were detected in the grass area off the parcel of interest.. November 28'was the last day required to scan the remaining area after airplanes had been moved. We therefore were able to scan eastwards to the taxiway limit line. The area south near Concord Aero Club building was also scanned for underground structures. Again no typical UST signatures were evident. Of note we discovered the large grazed storm drain catch basin at a mid point of eastern wall of MDPA building. This contained a 12" diameter concrete pipe that exited northwards to a point where an anomaly was detected which we believe to be a buried manhole. A line was detected underground to travel westwards under the fence and stopped on western side of roadway. On December 4`'a visit was made to check for potential interferences for future drilling operations. These interferences were painted on the ground and potential drill points were relocated to a"safer"area- Trusting we have performed this study to your satisfaction we look forward to hearing from you again. Please do not hesitate to contact me should you have comments or concerns_ Yours sincerely, 7. j'Simon J. Taylor W C`T G . C •moi-•-� C V 4 O r L N {\ L �O \ � C U , W O L d u .

Prior to boring, underground and above ground utilities will be located. To the extent possible, borings will be conducted so as not to disrupt activities at a project site. PRA shall obtain and review available public data on subsurface geology and if warranted,the location of wells within a quarter-mile of the project site will be identified. Boring equipment will be properly inspected prior to performing work. Subsurface investigations are typically performed to assess the lateral and vertical extent of petroleum hydrocarbons or other contaminants which might be present in soils and groundwater. Boring methods will be selected to optimize field data requirements as well as to be compatible with known or suspected subsurface geologic conditions. Shallow soil borings will be advanced dry using a truck-mounted geoprobe,unless site conditions favor a different boring method. No drilling fluids will be used during this boring method. The probe and drill rods will initially be thoroughly steam-cleaned before arriving on-site, to prevent the introduction of contaminants from off-site,and will again be steam-cleaned between borings away from boring locations. Working components of the rig(subs,collars and all parts of the rig chassis near the borehole)will also be steam-cleaned. Cleaned rods and other tools,if required, will be stored and covered when not in use. Decontamination of boring equipment will consist of steam cleaning,and/or Alconox wash. Cleaning operations will be observed by a representa- tive of this office and noted on the drilling log. Soil Sampling Protocol Soil samples are typically collected at 4-foot intervals with a sampler advanced 48 inches by a vibrating hydraulic ram. Additional soil samples may be collected based on significant lithologic changes and/or potential chemical content. Typically,soil removed from the top 42 inches of the plastic liner and the end cone will be used for visual logging purposes and disposed of. The bottom 6 inches will be saved for laboratory analysis. Soil samples from each sampling interval will be lithologically described by a PRA geologist or engineer in accordance with the Unified Soil Classification System. The exact depth of all borings to 0.5-foot will be determined in the field. Exploratory boring logs shall be prepared under the direction of a Registered Geologist. Typically,head-space analyses will be performed in the field to check for the presence of volatile organic compounds. Head-space analyses will be performed using an organic vapor analyzer (either an TIP, HNU, or OVM). Organic vapor concentrations will be recorded on the PRA field log of boring if deemed necessary. The selection of soil samples for chemical analysis are typically based on the following criteria: a. Soil discoloration b. Soil odors C. Visual confirmation or chemical in soil No. 03-360/7372-01 Appendix A Page 2 d. Depth with respect to underground tanks e. Depth with respect to groundwater f. OVA reading The soil sampler will be cleaned with a tri-sodium phosphate solution,rinsed with clean tap water and air-dried prior to each sampling. A clean,new plastic liner will be used for each sample point. Soil samples selected for chemical analysis are covered with aluminum foil and the ends are capped to prevent volatilization. The samples are labeled and entered onto a Chain-of-Custody form, and placed in a cooler on blue ice for transport to a State-certified analytical laboratory. Soil borings will be backfilled(sealed) to ground surface using either a neat cement or cement- bentonite grout mixture in accordance with appropriate local regulations. Pending results by laboratory analysis,excess soil and materials from the boring operations will remain on-site and, when deemed necessary, covered with a plastic tarp. Confirmed uncontaminated soils may be appropriately disposed of on-site by the client. Soils found to contain levels of contaminants above local or state action levels will be placed in properly labeled 55-gallon drums and left on-site for proper disposal by the client. At the client's request,we will act as the client's agent by assisting in the disposal of the drum-contained material. DOCUMENTATION Sample Container Labels Each sample container will be labeled immediately after the sample is collected. Label information will include: Sample point designation (i.e., well number or code) Sampler's identification Project number Date and time of collection Type of preservation used Chain-of-Custody A Chain-of-Custody record shall be completed and accompany every shipment of samples to the analytical laboratory in order to establish the documentation necessary to trace sample possession from time of collection. The record will contain the following information: Sample or station number or sample identification (ID) Signature of collector, sampler, or recorder Date and time of collection Place of collection Sample type Signatures of persons involved in chain of possession Inclusive dates of possession No. 03-360/7372-01 Appendix A Page 3 Samples shall always be accompanied by a Chain-of-Custody record. When transferring the samples,the individual relinquishing and receiving the samples will sign,date,and note the time on the Chain-of-Custody record. PRA will be responsible for notifying the laboratory coordinator when and how many samples will be sent to the laboratory for analysis, and what types of analyses shall be performed. Sample Handling Storage and Transport All chemical sampling, handling and storage will be conducted under the direction of our consulting Analytical Chemist All laboratory chemical testing will be accomplished by a State approved laboratory. All samples will be held at 4°C by packing in ice in a covered ice chest specifically designated for that purpose. At no time will the elapsed time between sample collection and delivery at the outside laboratory be greater than 72 hours. Preservatives will not be added to any sample unless instructed, and preservatives will be supplied and requested by the outside laboratory. Under no circumstances will sample containers be opened by anyone other than laboratory personnel who will perform the specified chemical analysis. If it is necessary for samples or sample chests to leave the immediate control of the sampler prior to delivery to the laboratory, such as shipment by a common carrier(e.g., Federal Express), a custody seal will be placed on each sample container and/or sample chest to ensure that the samples have not been tampered with during transportation. The custody seal will contain the sampler's signature, the date and time the seal was placed.

(ERG) provided the services of a Certified Asbestos Consultant (CAC) and DHS Certified Lead Inspector/Assessor, at the Buchanan Field Air—port. Property in Concord, CA. The services. included the identification of suspected asbestos containing materials, sampling of those suspect materials, sampling of surface coatings or materials per architectural component, delivery of the samples to a laboratory for proper analysis, travel and a written report with findings. Three structures were surveyed. Conditions ERG conducted a lead and asbestos survey for the structures as follows: Mount Diablo Pilots Association. — 220 Buchanan Field Drive, Concord Pilots Association — 226 Buchanan Field Drive and the Executive Hander - no physical address. It is understood that the survey was conducted to determine the presents of asbestos containing building materials and lead surface coatings or materials. ERG arrived on site on November 14, 2007 to perform the survey. ERG then collected samples accordingly. ERG conducted a pre-demolition survey of the buildings. There are three structures at the site. Building (l) — 220 Buchanan Field Drive is approximately 1000 square feet. Building (2) — 226 Buchanan Field Drive is 1. approximately 2500 square feet. Building (3) — Executive Hanger is approximately 8000 square feet. Asbestos Sampling The samples were collected using decontaminated tools and given unique sample numbers. The samples were sent to Asbestos TEM Laboratories, Inc. (ATL) in Berkeley, CA for analysis. ATL broke the samples into their structural matrix and analyzed the samples for asbestos fiber content using the EPA method Polarized Light Microscopy (PLM). The results are reported in percent of asbestos fibers in the sample analyzed. Zero percent asbestos fibers will result in a 'None Detected' sample. Less than 1% Mr.Joe Ambrosino Concord Field Airport Property December 17`h.2007 asbestos fibers will result in a 'Trace Amount' sample and one sample of that homogenous material will have to by point counted by PLM — Point Count Method to determine the actual percentage of asbestos fibers. All sample results above l% asbestos fibers will result in the materials being an Asbestos Containing Material (ACM). 220 Buchanan Field Drive (14) Samples were collected and sent for analysis. The laboratory broke the samples down into their structural matrix and conducted the analysis in accordance with the set laboratory protocols. (24) Analysis from the laboratory was conducted.
