DATE: November 14, 2006 PAGE: 2 III. Background and Reasons for Recommendations County Administrator's Report: On July 25, 2006, the Board of Supervisors directed the County Administrator's Office to work with the Director of Airports to research and evaluate the most effective methods for streamlining County policies and procedures to promote greater development at Buchanan Field and Byron Airports. During the month of August,the County Administrator's Office(CAO)and Public Works Department met twice to discuss the implementation of reorganized reporting lines associated with the County Airports. Specifically,the process for reporting issues and information between the Director of Airports and the CAO were clarified. Additionally, procedural items, (i.e. board orders, contracts, etc) were redirected from the Public Works Department, to the CAO in an effort to streamline administrative processes. In September the CAO,County Counsel,Public Works Department and County Airport staff met to discuss options for streamlining legal review processes. We gave consideration to hiring outside legal counsel to expedite the development of aviation related legal documents. However, it is recommended that those services continue to be provided by Public Works Department-Real Property Division and County Counsel staff so as to maintain consistency with County policies and legal requirements. Both the Public Works Department-Real Property Division and County Counsel agreed to dedicate greater resources to the Buchanan Field and Byron Airports development projects. Additionally,the Real Property Division agreed to develop, working with Airport and County Counsel staff, a template lease document for Byron Airport development in an effort to expedite the development process. The Real Property Division expects to complete the template within three to six months. Additional template lease documents for various aviation uses for both airports will then follow. In both September and October the CAO,County Airports,Building Inspection Department and the County Fire Protection District staff had meetings to discuss streamlining opportunities for the permit and plan review process of airport related development. It was determined that an aircraft hangar development guideline would be prepared and submitted jointly by the Building Inspection Department,Fire Protection District and Airports, to the Board of Supervisors for approval. Airport Subcommittee: In 1999 the Board of Supervisors established the Airport Ad Hoc Subcommittee. This committee has met on an as-needed basis over the past several years to address important policy issues, such as the possible reestablishment of commercial airline service at Buchanan Field Airport,proposed increases to airport fees, consideration of new noise abatement restrictions and selection of master developers. The economic and emergency response contributions of Buchanan Field and Byron Airports are vital to the County. Given the importance and complexity of Airport issues, (i.e. new Airport Master Plans and economic development opportunities)it is recommended that the Airport Subcommittee be reactivated and meet on a regular basis. IV. Consequences of Negative Action The County Airports will continue to experience delays with business processes and procedures related to airport development. This will make the County Airport less competitive and likely lose opportunities to develop at both Buchanan Field and Byron Airports. ADDENDUM to SD.6 November 14, 2006 On this day,the Board of Supervisors considered accepting the County Administrator's report regarding streamlining County policies and processes to promote greater development at Buchanan Field and Byron Airports, reactivating the Airport Subcommittee for the County Board of Supervisors, and appointing the District II and N Supervisors as members for calendar year 2007. Jason Crapo of the County Administrator's Office presented the item. Keith Freitas, Airports Director, commented that the recommendation to reactivate the Airport Subcommittee is the result of the increased frequency of issues. Supervisor Piepho said she hopes that rising concerns about fire suppression systems at the Buchanan Field Airport will be referred to the reactivated Subcommittee. The Chair called for public comment and the following people spoke: Dianne Cole,Friends of Concord Airport, implored the Board not to send the issue of fire suppression systems to the Subcommittee because time is of the essence. The Chair commented for the record that because the issue of airport fire sprinkler systems is not part of this agenda item the Board cannot take an action on the matter. He urged speakers who wished to comment on that matter to speak under general Public Comment, and asked that speakers under this item limit their comments to the matter before the Board. Kelly Rogers, Concord Jet, said he is the Project Manager for Concord Jet and said that he is held to a different standard in Contra Costa County; Pat Howlett, Concord resident, said the County departments should support the Board's directive to build Buchanan and Byron airports. He encouraged the Board to remove all stumbling blocks; Morris Care, Sterling Aviation, said the Ad Hoc Committee would be a good thing and that he wants the project to be safe; Eric Hasseltine, Pleasant Hill resident, said that the 11 new airport projects, of which at least three have signed agreements with the County already in place, represent what the Board has directed for the airports.He requested that the proposed Ad Hoc Committee meet as soon as possible; Russell Roe,Martinez resident, said conflicting permit processes have effectively shut down development at County airports. Supervisor Uilkema suggested the Bay Area Air Quality Management District(BAAQMD)be involved in the process, particularly in the discussion of fire suppression issues. Supervisor Glover suggested that, as District N has no sitting member on the Board until January of 2007,he could participate in the Subcommittee so that a meeting would not have to be postponed. SD.6 11/14/2006 Page 2 of 2 By a unanimous vote with District IV absent, the Board of Supervisors took the following action: APPROVED staff's report regarding streamlining County policies and processes to promote greater development at Buchanan Field and Byron Airports;REACTIVATED the Airport Subcommittee for the County Board of Supervisors and requested staff schedule a Subcommittee meeting as soon as possible; APPOINTED the District II and IV Supervisors as members for calendar year 2007,with the District V Supervisor to sit on the committee in the place of the vacant District IV seat; and DIRECTED the inclusion of the BAAQMD in the processes.

Supervisor Glover Supervisor DeSaulnier Supervisor Uilkema Contra Costa County Board Chambers Room 107 Administration Building 650 Pine Street Martinez, California 94553-1229 Re: Fire Sprinkler System Requirements for Airport Hangers DeNova Homes Inc. and Airport Properties Agenda Item SD.6. Dear Chairperson Gioia, Vice Chairperson Piepho and Supervisors Glover, DeSaulnier and Uilkema: This firm represents DeNova Holmes, Inc. and Airport Properties,project applicants regarding pending airport projects. It is our position that the National Fire Protection Association("NFPA") guidelines are inappropriately being applied to our client's hanger project at Buchanan Field Airport. Based on NFPA guidelines, the District Fire Marshal has suggested that: 1)the installation of a foam or chemical retardant system may be required, and 2) the suppression system runoff will be need to be contained by some sort of discharge tank. We disagree. Section 101.7 of the California Building Code ("CBC"), adopted by Contra Costa County, states that "when the building code does not specifically cover any subject relating to building construction, recognized fire prevention engineering practices shall be employed." In such a case, "The National Fire Codes and the Fire Protection Handbook of the [NFPA] may be used as authoritative guides."' Here, the CBC does ' See Letter from Carlos Baltodano,County Building Official,to Richard Carpenter,Fire Marshal(Oct. 9, 2006)(attached as Exhibit A). cover the classification, design and construction of aircraft hangers.2 Therefore, the NFPA guidelines are not applicable. Specifically, CBC provides that aircraft hangers are designated as having an occupancy classification of either H5 (Section 307.1) or S5 (Section 311.1). Though the CBC does classify aircraft hangers, it does not require sprinklers for either H5 or S5 occupancies. Rather, it is the Contra Costa County Code Building Regulations that amended CBC Section 904.2.1 to require the installation of fire extinguishing systems based on certain criteria.3 See Article 74-3.904.2.1.4 The question, then, is who has the authority to interpret and enforce the Contra Costa County Code Building Regulations? Article 72-2.0035 of the Contra Costa County Code Building Regulations provides the answer. It states that the County Building Official "shall administer and enforce state and county laws and regulations on buildings." Attached, as Exhibit A, is a letter by the County Building Official, Carlo Baltodano. As the letter reveals, Mr. Baltodano has already rendered a decision in this matter. It is the opinion of Mr. Baltodano and the Building Inspection Department that Article 74-3.904.2.1 applies to aircraft hangers. Thus,while automatic sprinklers may need to be installed, a foam or chemical suppression system is not required. Nor is containment of runoff necessary since Mr. Baltodano states that Article 74-3.904.2.1 governs the sprinkler requirements of airport hangers and that Article does not require any containment of suppression system runoff. Thank your for your consideration of these comments. But given the brevity of my remarks here, we respectfully request that the Board take the time to review the attached letters labeled as exhibits A and B. The letters are by your County's own staff and they discuss this issue in much greater depth and specificity than I have done here. This letter is being submitted in relation to Agenda Item SD.6 for the Board of Supervisors meeting of November 14, 2006. Please make this letter, including all attached Exhibits, part of the administrative record for this Agenda Item. 2 See Memorandum from Beth Lee,Airport Business&Development Manager,Public Works Department (Airports Division),Contra Costa County,to Keith Freitas,Director of Airports,Public Works Department (Airports Division),Contra Costa County(Aug. 31,2006)(attached as Exhibit B).

Contra Costa County Fire Protection District 2010 Cleary Road Pleasant Hill, CA 94523 Subject: Building Code Interpretation of Aircraft Hangers Dear Richard: First, I want to thank you for providing the Construction and Fire Protection Synopsis of Aircraft Hangers. It is a comprehensive compilation of the California Building Code (CBC) Chapters and the NEPA Standards relating to aircraft hangers. There are sections in your manual that I agree on and there are others I do not, I agree with the overall goal that we must as code officials provide a reasonable degree of protection from fire, life safety, and property in an aircraft hanger. As you indicated in your manual, Section 101.7 of the CBC does state "When the building code does not specifically cover any subject relating to building construction, recognized fire- prevention engineering practices shall be employed." It goes on to state, "The National Fire Codes and the Fire Protection Handbook of the National Fire Protection Association may be used as authoritative guides..." Please note the operative word"may". Occupancy In using the 2001 California Building Code (CBC) the occupancy classification for aircraft hangers is designated as H5 (Section 307.1) or S5 (Section 311.1). Please see attachment 1 and 2. Fire Extinguishing Systems In determining fire extinguishing systems for 145 and S5 the following process is used: a) Section 904.2.1 of the 2002 CBC does not indicate that sprinklets-are required for either H5 or S5 occupancies (see attachment 3). Interestingly enough,it is the Contra Costa County Code Building Regulation (Article 74-3.904.2.1) that amended the CBC Section 904.2.1 where fire extinguishing systems are required to be installed (see attachment 4). b) Section 904.1.1 and Section 904.1.2 indicate that fire extinguishing systems shall comply with Uniform Building Code(LJBC) Standards 9-1 and 9-2 (see attachment 5). UBC Standard 9- 1 is NFPA 13-1991. UBC Standard 9-2 is NFPA 14-1993 (standpipe systems). Standard 9-1 Volume 3 of the UBC indicates hazard classification under Table 1.4.7 (we attachment 6). In the table, an S occupancy is under Ordinary Group 2 in the hazard classification. For a Group H it is either hazard group 1 or group 2. In either hazard classifications a water sprinkler system is required. It is our opinion that aircraft hangers are classified as H5 or S5 and that the fire extinguishing system requirement is not due, to the 2001 CBC, but is required under Contra Costa Code Building Regulation amendments to the 2001 CBC. The Building Inq=tion Department enforces the LJBC Standards 9-1 and 9-2,which refer only to NFPA 13. Local fire districts may not enforce amendments to. Section 904.2.1, since .it is the Contra Costa Code Building Regulations, not the CBC that requires the fire extinguishing system. 'Therefore, it is the decision of the Building Inspection Department that foam is not required for either occupancy. If you have any questions regarding this conclusion please do not hesitate to give me a call at (925) 335-1108.

Fire Chief-Operations, CCC Fire Protection District Keith Freitas,Buchanan Airport Manager,Public Works Department Beth Lee, Buchanan Airport Business and Development Manager, PWD FROM Carlos Baltodano, Director SUBJ October 12, 2006 meeting at Buchanan Airport As we discussed earlier this morning, I am faking to you sections of the Uniform Building Code (U13C) Standards 9-1 where it contains the exceptions to NFPA 13. Please note that in Part 1, Section 9.101-.Amendments, it states that "The National Fire Protection Association standard adopted by this standard applies to the selection, installation, acceptance inspection and acceptance testing of sprinkler systems, except as follows..." Further note that Table 1.4.7- Hazard Classification specifically lists the occupancy classifications as defined in the UBC. The occupancy type refers to a hazard classification. The NFPA 13 standards general requirements are also incorporated and the scope "provides minimum requirements for design and installation of automatic fire sprinkler systems and exposure protection sprinkler systems including the character and adequacy of water supplies—." In summary, this code section clearly states that extra hazard group 1 or ordinary group 1 or 2 automatic sprinkler systems shall be used in S and H occupancies. As T indicated this morning this amendment to the NFPA standards was included to relate S and H occupancies in the building code with requirements for sprinklers within NFPA 13. Once the hazard classification has been determined then the sprinkler system is designed accordingly(please see Table 4-2.2).

Per Chapter 72-2 Building Inspection Department of the County Code,the building inspection department and director shall administer and enforce state and county laws and regulations on buildings, as ordinance or board resolution provides. The building director is empowered to render interpretations of the Code and to adopt and enforce rules and supplemental regulations to clarify the application of its provisions.The interpretations,rules, and regulations must conform to the intent and purpose of the Code. When the"Code does not specifically cover any subject relating to building design and construction, recognized fire-prevention engineering practices shall be employed.The National Fire Codes and the Fire Protection Handbook of the National Fire Protection Association may be used as authoritative guides in determining recognized fire-prevention engineering practices." The Code does specifically cover the classification,design and construction of aircraft hangars and, as a result, the provisions provided within should be governing parameters. Specifically, Section 307 states that H-5 is the classification for aircraft repair hangars not classified as Group S, Division 5 (5) occupancies and heliports. Group H occupancies include buildings or structure, or portions thereof, that involve the manufacturing, processing, generation or storage of materials that constitute a high fire, explosion or health hazard.Fixed base operations, specialty aviation, maintenance facilities and the like are examples of the Group H occupancy. Section 307,in combination with all other Code sections,provides all the design and construction requirements for this occupancy group. Per Section 311, Group S-5 are aircraft hangars where work is limited to exchange of parts and maintenance requiring no open flame or welding and helistops. Section 311,in combination with 1 all other Code sections, provides the design and construction requirements for this occupancy group. Executive,t-, box and shade hangars are examples of this occupancy group. Consistent with the Code, the Group S hangar type was the subject of the County building officials' June 23, 2006, occupancy and fire protection determination: "We have reviewed the construction type and fire requirements for the proposed airport hanger at Buchanan Airport. While we have not received any plans on the project per discussions with all of you,it is known that the construction will be an aircraft hanger where maintenance or repair of aircraft will not occur. I have carefully reviewed both the Uniform Building Code requirements and NFPA standards (409) on aircraft hangers as submitted by Rick. We have determined that based on Table 3-A of the 2001 California Building Code (CBC) the description of the occupancy by group and division most likely resembles a S-5 group and division (storage). The 2001 CBC does categorize an aircraft hanger under the S-5 category. The requirement per Chapter 9 of the Building Code is that the building be sprinklered. It does not require that the NFPA 409 be used. It is our opinion that the application of foam is not a requirement per the code." Chapter 9,Fire Protection System, of the Building Code requires automatic fire-extinguishing stems to be installed in new buildings when (1)the total floor area, including mezzanines, exceeds ten thousand square feet; or(2) in all buildings separated by one or more area separation walls without openings when the total floor area, including mezzanines, exceeds twenty thousand feet(some exemptions are noted but they do not relate to airport uses). This is an added provision applicable to Contra Costa County. In addition, Chapter 9 provides fire alarm system requirements for Group H occupancies. Chapter 9 is silent to Group S occupancies, meaning it does not apply to structures that are less than 10,000 square feet in total area or 20,000 square feet with separation walls. Thus,per the County building officials' determination above, Group S-5 hangars that exceed the floor area thresholds will be required to provide an automatic water sprinkler system, The Code does not address containment requirements for the water sprinkler system. I contacted a supervisor structural engineer with the County Building Inspection Department and found that the Code does not require containment of water sprinkler systems. I also contacted the Environmental Division of the Health Services Department and found that they would not require a containment system and if one were to be provided, it would be exempt from their permitting requirements (since it is designed to only be used in an emergency). The Code is dense with guidance material which could be paraphrased here. However,enough of the basic points have been provided and, as such, a few basic questions arise: 1. Since the County building official(per Code)has made the occupancy determination of S-5 for storage hangars, why is this determination being questioned rather than accepted? 2. Since the Code does not require containment for automatic water sprinkler systems and no other ordinancelpolicy has been provided for such authorization, why are S-5 2 11 A occupancy hangars required to construct containment? Where is the authority to require this and is it legally enforceable? 3. Since it has been determined that only a water system is required, what would be the nexus connection to request more out of a developer of a Group S hangar(either foam, fire station construction or any other request)? cc: KC Coyle,Operations Manager Chapter 74-3 MODIFICATIONS Page 1 of 1 Article 74-3.9. CBC Chapter 9 Fire Protection Systems IbR 9 I 74-3.904.2.1 Automatic fire extinguishing systems. CBC Section 904.2.1, automatic fire extinguishing systems, is amended to read: "(a) For new buildings an automatic fire extinguishing system shall be installed: 1. In all buildings when the total floor area, including mezzanines, exceeds ten thousand square feet. 2. In all buildings separated by one or more area separation walls without openings when the total floor area, including mezzanines, exceeds twenty thousand square feet. Exceptions to (a)1 and (a)2: A.

C. When determining a building's total floor area, the floor area of mechanical rooms of not more than fifty square feet and separated from the remainder of the building by not less than a one hour fire resistive occupancy separation need not be considered. D. Nothing in this code prevents the application of more restrictive automatic fire extinguishing system requirements in those fire protection districts which have more restrictive requirements. For purposes of this section, "new building"includes a building which replaces a preexisting building which has been substantially destroyed. The county building official shall determine whether a building has been substantially destroyed.

While we are pleased that much progress has been made toward streamlining the process for business development at our airports, it appears we have hit a brick wall. I have grave, concerns at the latest attempts to prevent improvements from going forward at Buchanan Field and Byron Airport. I am referring to the Fire Marshal insisting that his view on building plans usurps the County Code and the Building Department. The Fire Marshal has no authority to insist upon standards more stringent than the county code requirements. The codes the fire marshal refers to,were written by an insurance company sponsored organization and have no binding compliance requirements,they are advisory only. They are not included in the Uniform Fire Code, which is the national standard for fire protection. Mr. Carpenter is either misinformed, or has an agenda other than his job.The intransigence of the fire marshal to approve pending projects will bring improvement plans at both airports to a crashing end and further brand our county as not encouraging business development. This has to change. Mr. Carlos Baltodano,the Director of the County Building Inspection Department has gone on record justifying his position to approve the permits. I note Mr. Carpenter,the Fire Marshal is unwilling to put his requirements in writing, because he knows they are not in compliance with national or county codes. The Board of Supervisors should insist the established codes and procedures be adhered to by the Fire Marshal.After all,the Building Department is the lead agency in the permit process. I implore the board NOT to send this dispute to the ad-hoc committee for further study, or request the county administrator look into it and report back to the board. Time is of the essence and this is a clear cut issue that can and should be acted upon here. With this hurdle cleared,the county can look forward to many new projects,bringing needed facilities,jobs and revenues.

Unfortunately, your acceptance and endorsement of the report will be for naught if you do not quickly resolve the conflict between the Fire Department and the Building Department regarding the type of fire suppression system(and its foam containment) to be used in new hanger development now being proposed. Please consider the following: Safety and Risk: Obviously, these matters are paramount to your decision. However, please examine the level of risk that the Fire Department's foam system purports to mitigate. The property (and human life) loss data does not support the use of this system. Additionally, Buchanan currently has foam suppression equipment on site and Station 11 (at 209 Center) s less than three minutes away. Finally, Airport Staff has a revealing video showing the risks of the foam system insisted on by the Fire Department. 1 understand that even the military is backing away from these types of foam systems because of the risk of accidental release. Economic Development Current Board policy wisely requires the economic development of its airports. Over $100 million(that's right, $100 million) in development proposals is currently in the pipeline. The prohibitive cost of the Fire Department's proposed 3068 Oakraider Drive 1 Alamo, California 94507 David Dol F1ICP _ 0.21 E. p._-.z -- --. p�;,- 10,: 46x. . . - _ - foam sy'stern will stop this development in its tracks, as airport developers will no doubt testify to tomorrow. Legal Liability The Courity may not be without legal liability in this matter. Work already started on some hanger protects when the Fire Department erroneously concluded that it needed the system it endorses. Now it says it will not sign off on any further permitting for these on-going projects. If the County does not issue further permits, will the County be liable for development costs spent to date by these tenants? Additionally, what is the County's exposure when the accidental release of foam destroys a $25 million jet? Faulty Code Interpretation The Fire Chief and Fire Marshall erroneously assert that the National Fire Protection Codes and the Fire Protection Handbook of the National Fire Protection Association are the governing regulations. The Building Official correctly asserts otherwise. These are reference documents only to be used for guidance when certain systems are implemented. They are not code. Conclusion The Fire Department's proposal is overkill and unreasonable based on the level of risk and the number and type of incidents that have occurred. If imposed, the Board's airport economic development policy will be moot. This matter should be resolved by re-activating the Board's Airport Subcommittee and referring this matter immediately to thern for a quick resolution. Thank you for your consideration.

Our understanding is that he is basing this opinion on the requirements of NFPA (National Fire Protection Association) 409, the Standard on Aircraft Hangars specifically for Group II Hangars. Our initial response is that we have been developing aircraft hangars around the country for the express purpose of private aircraft storage and have never been required to conform to the more restrictive requirements of NFPA 409. We have never been required to provide any type of foam fire suppression system nor extensive systems for containment of fire sprinkler discharge in any previous facility. Secondly, the cost of providing these systems will run into the millions of dollars and will make the price, and therefore the development of new hangars, for private aircraft owners prohibitive. Our third response is more complicated and involves the review of the current codes affecting the construction of private aircraft hangars. The current building code governing construction in Concord, CA is the 2001 California Building Code (CBC). The CBC is based upon the 1997 Uniform Building Code (UBC). Beginning in 2000 the Uniform Building Code was replaced with the International Building Code (IBC), and is updated every three years just like the previous UBC. Many jurisdictions take a few years to adopt the latest code after it is first released. Our understanding is that sometime in 2007, California will adopt the IBC as its base code with some modifications and additions, as they did with the 1997 UBC. Nov T4 -2G06 10: 48RM Wagner Rrchitectural Team 303 690 8948 p. 3 Page two - November 14, 2006 CCC Board of Supervisors NFPA 409 is a specific code section put forward by the National Fire Protection Association that pertains to aircraft hangars. NFPA 409 lumps all aircraft hangars into one classification which includes aircraft storage, service, repair, and alterations. The 1997 UBC and therefore the 2001 CBC differentiate between Aircraft Repair Hangars (classified as Group H, hazardous, Division 5), and Aircraft Hangars where work is limited to exchange of parts and no open flame or welding (classified as Group S, storage, Division 5). The 2001 CBC does not incorporate NFPA 409 into its requirements. When and if California adopts the new IBC, there are also provisions in this new code that pertain to the storage of private aircraft as separate from the storage of commercial aircraft and the major maintenance, repair and overhaul of all aircraft. "Section 412..2.6 Fire Suppression"of the 2000 IBC specifically exempts storage of private aircraft from the foam fire suppression requirements of NFPA 409. It seems that NFPA 409 is blind to the differences between private and commercial aircraft storage, and between aircraft storage and major aircraft repair. However, the codes currently in place in California and those likely to be adopted in the future take into account those differences and make specific and less restrictive requirements for their use. The major acknowledgements of those differences is the elimination of the need for foam fire suppression systems and containment systems for fire sprinkler flows in hangars where there is only storage of private aircraft without major maintenance or overhaul. We believe that the provisions of the CBC and not those of NFPA 409 should be the governing requirements for private aircraft hangar development at the airport since they are more specific to those types of uses. We hope the Airport Board shares this,-view so that we and others can proceed with airport related development at Buchanan Field. Sincerely, Douglas R.
