Direct Staff to post the Notice of Determination with the County Clerk and the Govenor's Office of Planning and Research for the above actions. FISCAL IMPACT Covered by Developer fees. BACKGROUNDJREASONS FOR RECOMMENDATIONS On May 23, 1995 the Board closed the hearing on 2963-RZ (Discovery Bay West) and directed staff to prepare final documentation for the rezoning project. Staff has prepared Revised Conditions of Approval for the remainder of #2963-RZ (Attachment A) . References to requirements for Village I have been deleted as that area has already been approved for Rezoning to P-1. Also, the Contra Costa County Flood Control and Water Conservation District has requested that reference to their Agency be deleted on pages 3 , 4 and 85 of the Mitigation Monitoring Program. This reference was in error. Contra Costa County Public Works Department would be the monitoring Agency in this case. Staff has no objections to these requested changes. to the Mitigation Monitoring Program (the changes are detailed in Attachment C) . The CEQA Findings need slight changes so that they no longer refer to Village I only. On Page 5 of the CEQA Findings, 3rd paragraph, the section of the first sentence "and is the only phase that is rezoned at this time," should be deleted. Two sentences at the end of the above paragraph need to be added to read as follows "Village I has already been rezoned. Villages II, III and IV are the only phases of the project that are being rezoned at this time." On Page 3, top paragraph, of the Mitigation Monitoring Program the sentence "Only the Mitigation Measures impacts that relate to Village I are implemented in this Mitigation Monitoring Program." should be deleted. These modifications to the previously supplied Findings and Mitigation Monitoring Program are indicated in Attachments B and C. ADDENDUM TO ITEM D. 5 JULY 9, 1996 On June 4 , • 1996 , the Board of Supervisors continued to this date the decision on the remainder of the phases for the Discovery Bay West Project (2963-RZ) in the Discovery Bay area. Dennis Barry, Community Development Department, presented the staff report on the material before the Board for consideration, and he commented on minor modifications on conditions relating to the community center and the community warning system and he advised of the staff recommendations before the Board for consideration including the oral modifications to the conditions of approval . Supervisor Torlakson moved to approve the staff recommendation as outlined and to authorize the District Supervisor to meet with the parties and try to facilitate a resolution of the location and details of the community center proposal and to report back to the Board on the progress and results of that process . Supervisor Bishop commented on her concerns in areas including schools, buffering, wetlands replacement and water and she advised she would not be supporting the motion. Supervisor DeSaulnier seconded the motion. IT IS BY THE BOARD ORDERED that recommendation 1, 2, 3 , 4, 5, and 6 are APPROVED; and Ordinance No. 96-13 , giving effect to the rezoning is INTRODUCED, reading waived and July 16 , 1996 , is set for adoption of same; and the Supervisor representing District V is AUTHORIZED to meet with the parties to facilitate a resolution of details regarding the proposed community center and to report to the Board of Supervisors on the results of that process .

The added level of funding is intended to be used for augmented marine patrol services, especially the enforcement of boat speed limits. In the event that the State determines to subvent the costs of marine patrol prior to the filing of a final map, this requirement for the additional $25.00 shall be null and void. EMF Notification 9. Where a lot/parcel is located within 300 feet of a high voltage electric transmission line, the applicant shall record the following notice or other appropriate notice as approved by the Zoning Administrator: "The subject property is located near a high voltage electric trans- mission line. Purchasers should be aware that there is ongoing research on possible potential adverse health effects caused by the exposure to a magnetic field generated by high voltage lines. Although much more research is needed before the question of whether magnetic fields actually cause adverse health effects can be 6 resolved, the basis for such an hypothesis is established. At this time no risk assessment has been made." When a Final Subdivision Public Report issued by the California Department of Real Estate is required, the applicant shall also request that the Department of Real Estate insert the above note in the report. Farm Operation Notice 10. The following statement shall be recorded at the County Recorder's Office for each parcel to notify future owners of the parcels that they own property in an agricultural area (MM 4.5 and MM 7.2): "This document shall serve as notification that you have purchased land near an agricultural area where you may regularly find farm equipment using local roads, farm equipment causing dust; crop dusting and spraying occurring regularly; burning associated with agricultural activities, noise associated with farm equipment and aerial crop dusting and certain animals and flies may exist on surrounding properties. This statement is, again, notification that this is part of the agricultural way of life near the open space areas of Contra Costa County and you should be fully aware of this at the time of purchase." Archaeolo6cal Concerns 11. Should archaeological materials be uncovered during grading, trenching or other on-site excavation(s), earthwork within 30 yards of these materials shall be stopped until a professional archaeologist who is certified by the Society of Professional Archaeology (SOPA) has had an opportunity to evaluate the significance of the find and suggest appropriate rnitigation(s), if deemed necessary and subject to Zoning Administrator review and approval. (MM 11.1) A. If any significant cultural materials such as artifacts, human burials, or the like are encountered during construction operations, such operations shall cease within 30 yards of the find, the Community Development Department shall be notified within 24-hours and a qualified archaeologist contacted and retained for further recom- mendations. Significant cultural materials include, but are not limited to, aboriginal human remains, chipped stone, groundstone, shell and bone artifacts, concentrations of fire cracked rock, ash, charcoal, shell, bone, and historic features such as privies or building foundations. (MM 11.1) A 7 B.

The County will promptly notify the subdivider of any such claim, action, or proceeding and cooperate fully in the defense. 9 Wave Action from Boating and Bank Erosion 16. Prior to development of the marina the requirements regarding wave impacts from increased boating must be properly mitigated per the adopted Mitigation Monitoring Program. MM 1.1.7. Protect Construction 17. The project applicant will be required to comply with all necessary permits, including but not limited to, the NPDES permit for Storm Water Discharges Associated with Construction Activity as well as applying for inclusion in the General Stormwater Permit issued by the State of California. The project applicant must also comply with all requirements of construction permits for Contra Costa County. The applicant must obtain C.W.A. Section 404 and Section 10 permits from the Army Corps of Engineers for construction in wetlands and navigable waterways for the marina as required by law. (MM 1 . 1.S) Ground Water Hydrology 18. The developer shall participate in the establishment, prior to development of the site, of a Iona term water quality management program, comparable to a program recommended by Luhdorff& Scalmanini of the degradation of ground water quality. The appropriate mon- itoring program will be one that identities changes in quantity and quality of water and pro- vides for responses to these changes in a timely fashion. This can best be accomplished by establishing a multi-aquifer monitoring network' in cooperation with local agencies such as the BBID, Delta Diablo Sanitation District (Sanitation District #19) and ECCID. Means acceptable to Sanitation District #19 to finance the long term monitoring program shall be developed prior to site development. The long-term monitoring program shall include measures outlined in the Adopted Mitigation Monitoring Program acceptable to Sanitation District #19. (N1M 1.2.1.) 19. As recommended in Condition 918, above in the mitigation of the degradation of groundwater quality and in the Luhdorff & Scalmanini reports, the developer shall participate in the establishment, prior to development of the site, of a long-term monitoring plan for the aquifer (regular monitoring of water supply wells currently in Discovery Bay, water supply wells outside of the developments, and monitoring wells capable of monitoring multiple aquifers) would identify changes in the quantity of water. Aquifer capacity and renewable resources should be documented and properly managed to prevent overdraft. If recoverable storage capacity of the aquifer is insufficient, an additional water supply source shall be investigated and developed. Means acceptable to Sanitation District 419 to finance the long term monitoring program shall be developed prior to site development. The long term monitoring plan shall include measures outlined in the mitigation monitoring program acceptable to Sanitation District 419. (MM 12.2) Y. 10 Vegetation and Wetlands 20. The following measures are required for impacts to vegetation and wetlands. (MM 2.1.1) A. Jurisdictional wetlands lost as a result of direct impacts of the project shall be compensated by the restoration or creation of wetlands at a minimum ratio of I:1. Loss of significant natural wetland communities should be compensated for at a higher ratio to be determined by parties involved and the Corps of Engineers as part of the Section 404 permit process. B. Compensation should be of the same habitat type as affected wetlands (i.e., in-kind replacement) whenever feasible, or with the approval of Corps of Engineers, shall be of habitats of higher botanical and wildlife value. Mitigation areas should be on- site, if practicable, or located off-site within reasonable proximity to the project site. County policy requires that the mitigation site be located within Contra Costa County. C. Mitigation wetlands should be located in a large contiguous parcel with transitional zone and adjacent upland habitat to maximize the likelihood of success in creating habitat capable of maintaining viable populations of native plant and animal species. A buffer zone (preferably 50 ft. or greater in width) should be established and maintained around the edges of all wetland and terrestrial habitat used as mitigation for project impacts. 21. The following requirements are required for the mitigation of the damage to special status plant species. (MM 2.1.2) A. The first choice in mitigation would be to alter the project plan to avoid direct impacts on both individuals and habitats of these species. If such action is to be taken, steps must also be taken to ensure that indirect impacts associated with the project throughout its life do not significantly impact these special-status plants and their habitat. Alternatively, subject to measures outlined in the Mitigation Monitoring Program the project applicant shall establish replacement special status plant communities located either on-site or off-site within reasonable proximity of the project. Advice on the mitigation project shall be sought from the California Department of Fish & Game. A means to fund over-site, long term shall be developed for this condition prior to development of a site containing or causing such an impact. 11 Mosquito Abatement 22. Work with the Contra Costa Mosquito and Vector Abatement District staff to develop a mosquito source reduction and management plan. The developer shall cooperate with District staff in the development of a mosquito monitoring and source management plan. Applicant shall fund the development of the plan. Impacts to Special Animals 23. Impacts to Delta Smelt. (MM 2.2.5) Prior to site development in any phase of project proper steps to implement the provisions of the adopted Mitigation Monitoring Program in regards to Delta Smelt shall be taken. 24. Impacts to Southwestern Pond Turtle. (MM 2.2.6) Prior to site development in any phase of project proper steps to implement the provisions of the adopted Mitigation Monitoring Program in regards to Southwestern Pond Turtle shall be taken. 25. Impacts to Swainson's Hawk. (NINI 2.2.8) Prior to site development in any phase of project proper steps to implement the provisions of the adopted Mitigation Monitoring Program in regards to the Swainson's Hawk shall be taken. 26. Impacts to Burrowing Owls. (MM 2.2.9) Prior to site development in any phase of project proper steps to implement the provisions of the adopted Mitigation Monitoring Program in regards to the Burrowing Owls shall be taken. 27. Impacts to San Joaquin Kit Fox. (MM 2.2.10) Prior to site development in any phase of project proper steps to implement the provisions of the adopted Mitigation Monitoring Program in regards to the San Joaquin Kit Fox shall be taken. Noise Impacts 28. Noise impacts to wildlife. (MM 4.2) Prior to site development in any phase of project proper steps to implement the provisions of the adopted Mitigation Monitoring Program in regards to wildlife shall be taken. 12 29. Noise conflicts between proposed uses. (NIM 4.8) New residences must be constructed so that interior DNL is 45 dBA or less and so that indoor noise levels due to single noise events shall not exceed a maximum of 50 dBA in the bedroom and 55 dBA in other habitable rooms. Geology. Soils and Seismic Hazards 30. The excavation of soil around the marina and lakes must be rigorously observed by trained professionals to identify any loose, clean sand and silt and peat in cut slopes; these should be excavated and replaced with compacted fill that includes a buttress that has been properly keyed into native soils and sediments and that has been properly constructed with engineered fill. A soils/geotechnical professional site acceptable to the Zoning Administrator shall be employed to monitor this measure as needed. (MM 3.1) A. The proposed mitigation for preventing groundwater flow from the brackish aquifer into surface water is to actively monitor excavation of the lakes. When flow from sands is identified, the sand should be excavated and replaced with buttress fills, keyed into less permeable clay-rich formations below the sand and constructed of compacted clay-rich soils to discourage active flow from the aquifer. (MM 1.2.4) B. The proposed mitigation for the flow of loose soil into the lakes is the same as for mixing of groundwater and surface water. Excavation should be actively monitored, and sands from which groundwater flows, which may erode the loose (heaving) sands, should be excavated and replaced with buttress fills, keyed into less permeable clay-rich layers below and constructed of less permeable material to discourage flow. (MM l 2.5) C. At least 45 days prior to recording.a Final Map, issuance of a grading permit, or installation of improvements or utilities, submit a preliminary geology, soil, and foundation report meeting the requirements of Subdivision Ordinance Section 94- 4.420 for review and approval of the Zoning Administrator. Improvement, grading, and building plans shall carry out the recommendations of the approved report. D. The report required above shall include evaluation of the potential for liquefaction and seismic settlement. E. Record a statement to run with deeds to the property acknowledging the approved report by title, author (firm), and date, calling attention to approved recom- mendations, and noting that the report is available frorn the seller and/or the County. 13 F. At least 45 days prior to issuance of permits to grade and create the lakes on the site, a suitable geotechnical report shall be submitted for the review and approval of the Zoning Administrator detailing means to stabilize the lake bank in case of earthquake and reduced possible liquefaction dangers in this area. Impacts on Agricultural Lands 31. Suitable fencing shall be developed around projects perimeters to separate residential uses from surrounding agricultural lands and activities. (MM 7,3) Equitable sharing of the cost of the initial (and any subsequent) fence constructed to deter trespassing, etc., is to be arranged between the primary developer and any other developer who is active in the project area and benefits from the fencing if possible to do so. Impacts on School Districts 32. The Discovery Bay West project shall assure the provision of adequate school facilities and levels of service from school districts serving the project, by way of the executed School Mitigation Agreement, which School Mitigation Agreement shall contain provisions and provide for payment to affected school districts in amounts determined in the agreement between the developer and school districts, in order to mitigate the impacts of their projects on school facilities. (MM 8. 1. 1, S. 1 .2, S. i.�) Increased Demand for Water and Sewer Systems 33. The site for Discovery Bay West shall be annexed into Contra Costa Sanitation District 919 prior to recording the final map on any portion of the development. (MM 8.3) A. Completion of a water supply study and a water system master plan acceptable to CCCSD 19 for the area within the Urban Limit Line is required as a condition of project approval. The study must define a funding mechanism that ensures new development pays for improvements to serve it exclusively. B. In the study of water supply, include consideration of how to reclaim water and reuse it. Reclaiming water and using reclaimed water are encouraged by the County General Plan. 34. Annexation of the proposed project area into Sanitation District 19, predicated on agreement by the district and The Hofinann Company on condition for annexation and fulfillment of such conditions within an agreed-on schedule. Conditions would include determination of technical standards and design of the expansion of the existing sanitary sewer system. (MM 8.4) 14 Police Protection 35. Measures to reduce or prevent crime incidents should be coordinated and include both physical design measures (including lighting for streets, parking areas, and entries; clear .=> 0 1"D 1*= address signs; door and window security design and locks), social measures (including neighborhood crime watches, anti-violence support groups, and education programs), and legal measures (control in selected areas for selected types of water activities, e.g., swimming,jet skis, etc.). Plans to accomplish the above shall be submitted to the Contra Costa County Sheriffs Department for comment prior to development of the site. (MM 8.7) Fire Protection 36. Before recording any Final Mal) negotiate to design, construct, and equip a fire station for In service to the project area as required by the East Diablo Fire Protection District or its representatives. The construction of the fire station can either fully or partially satisfy fire fees. Later nearby developments may be required to reimburse the developer on a pro-rata basis. The primary developer must also design streets and other features in the project area to accommodate fire and other emergency vehicles, (MNI 8.8) Park and Recreation Facilities/Recreation Uses .37. General Plan standards for neighborhood park acreage and facilities are to be met by the proposed project through arrangements acceptable to the Community Development Department by The Hofmann Company, such as the provision of"common area" acreage for recreational use. Suitable improvement of the public park may be used to partially meet park requirements as can Lip to 50% of the private outdoor recreational area if large enough and high quality enOLI-h private outdoor recreational areas are provided within the gated community. 38. Transfer of responsibility for security and management of the ECCID canal from the Irrigation District to another entity Such as the East Bay Regional Park District, which has expressed an interest in the canal easement for development as a regional trail shall be pursued. If an agreement cannot be made, The Hofi-nann Company may need to make other arrangements with the Irrigation District, Such as the addition of a suitable security fence. Right of Farminy , Ordinance 39. If the County's right to farming ordinance has been adopted prior to the issuance of building permits on this site, the developer shall inform future owners of that ordinance informing them of the right to farm within the Contra Costa County area. Z- 15 Removal of Existing Water Wells/Hazardous Chemicals on Site 40. Any hazardous chemical stored on the site shall be properly removed and disposed of under County Health Services Department regulations. Any existing water wells on the site shall be properly capped under County Health Services Department regulations. A Level I hazardous waste assessment shall be conducted on the site prior to filing of any Final Map that verifies that the site does not contain any hazardous waste. Irriy,ation Districts 41. Prior to recording the final map for phases on this site, confirmation shall be received from the Byron-Bethany Irrigation District and East Contra Costa Irrigation District that any facilities they have on the site have been properly moved or removed as the case may be, or as an alternative a letter from the District may be submitted indicating that they have no facilities on the site that will be disturbed as a result of this development. East Bay Municipal Utility District Chlorine Facility 42. At present the East Bay Municipal Utility District stores gaseous chlorine one-half mile north of the north end of the Discovery Bay West site. There may be plans to remove the gaseous chlorine from the facility in the future. However, this has not been decided yet. If, when development starts on this site, the gaseous chlorine facility is still in place then the developer shall accomplish the following prior to the issuance of the First Final Building Permit for this project: A. Give all residents, homeowners, and renters full disclosure regarding the presence of chlorine at the EBMUD Bixler site. B. The development shall support a proportionate share of the cost of the Community Warning System (CWS), the emergency notification system being installed throughout the County (which will include the installation of a siren system). The system is designed to warn the residents of the development if a large scale accidental release of hazardous materials occurs. C. The developmentshall ensure that the homes are as air tight as feasible by providing superior window seals, door seals, positive closure for fireplace dampers, etc. A periodic replacement program should be established as seals have a finite life. (To reduce indoor air pollution, the homes should be thoroughly ventilated prior to occupancy.) D. All homeowners shall be provided with sufficient information regarding shelter-in- place and the actions that should be taken in the event of an accidental chemical release. 16 These instructional materials shall be written in plain language, and will be developed in consultation with the Hazardous Materials Division of the County Health Services Deaprtment, subject to the review and approval of the Zoning Administrator. If the facility is removed or the process is changed then this requirement can be deleted subject to Zoning Administrator approval after review by the Hazardous Matreiais Division of the County Health Department. If, upon further review by the Hazardous Materials Division of the County Health Department, it is determined by the Health Department that the chlorine facility could not have a significant effect on Village I, then the above condition can be modified subject to Zoning Administrator review and approval. 43. A homeowners association will be required in Villages II, I11 and IV for the maintenance of the private roads, lakes, recreation areas, marina, trails and other landscaped areas. Road and Drainage 44. The following requirements pertaining to drainage, road, and utility improvements will require the review and approval of the Public Works Department. A. ORDINANCE REQUIRENIENTS: The applicant shall be required to comply with the requirements of Title 9 of the County Ordinance Code which include, but are not limited to the following requirements: 1) In accordance with Section 92-2.006 of the Ordinance Code, this subdivision shall conform to all applicable provisions of the Subdivision Ordinance (Title 9). Any exceptions therefrom must be specifically listed in these conditions of approval. The drainage, road and utility improvements outlined below shall require the review and approval of the Public Works Department and are based on the Vesting Tentative Map, Final Development Plan dated March, 1995, submitted to Public Works. An exception to allow a 0.75% minimum grade is allowed subject to Public Works approval providing: a. The soil engineer recommends reduced grades and signs the improve- ment plans; and V. 17 b. The applicant warrants the curb flow from ponding for five years following completion. The curb shall be inspected and repaired annually. 2) Division 914 of the Ordinance Code requires that all storm waters entering or originating within the subject property shall be conveyed, without diversion and within an adequate storm drainage facility, to a natural watercourse having definable bed and banks, or to an existing adequate storm drainage facility which conveys the storm waters to a natural watercourse. This project necessarily involves some diversions of watershed. However, since these diversions generally discharge to tidal bodies of water with adequate cross section and capacity, these diversions may be considered appropriate, subject to review and approval of Public Works. 3) Conveying storm waters in an adequate storm drain system to a: duly organized Homeowner Association; Municipal Improvement District, or Reclamation District drainage facility serving the area, is acceptable, provided the applicant obtains a letter from that entity accepting the drainage. Provide appropriate drainage releases where public waters enter private facilities. 4) Diversions resulting in discharge of storm waters into the Contra Costa Canal or any other water conveyance or impounding facility for domestic water consumption is prohibited by the Ordinance Code. It is acknowledged that Agricultural lands presently drain to the ECCID facility. Landscaped areas, so long as they do not create diversions, may follow pre- existing drainage patterns, subject to review and approval of Public Works. 5) For anything in these conditions of approval, which is subject to the approval of Public Works, such approval shall not be unreasonably withheld. B. TRAFFIC MITIGATION FEES: The project traffic mitigation fees will be collected at the time of the Building Permit for each residential unit of this development. No mitigation fees will be collected from non-residential construction. The project traffic mitigation fee shall consist of: * The Eastern Contra Costa Subregional Transportation Mitigation Fee (ECCSRTMF). This fee is for construction of the State Highway 4 Bypass. * The East County Regional Area of Benefit fee (ECRAOB). This fee is to improve local roads identified on the Circulation Element of the County General Plan. lam. 18 * The Project Traffic Mitigation Fee. This fee is $6,500 (revised annually to reflect inflation, using the State of California Construction Cost Index as published annually by Caltrans, as a reference) less the East County Regional Area of Benefit fee and is used to mitigate project impacts not covered by the above fees. The difference between the adjusted $6,500 Project Traffic Mitigation Fee and the ECRAOB fee shall be put into an interest earning Road Improvement Trust (Fund No. 819200-0800 or other project specific fiend) to be used to mitigate off-site local road and intersection improvements as reasonably determined and approved by the Public Works Department, which are identified in the EIR or the Flexible Mitigation Monitoring Program, and are not included in an established area of benefit. These funds will not be used for on-site improvements; frontage improvements, the off-site improvement of Bixler Road fi-om the project to State Highway 4; improvement of Point of Timber Road from Bixler Road to Byron Highway; the project's 50% share of the signal at the Bixler Road-State Highway 4 intersection; signalization of the State Highway 4-Discovery Bay Boulevard intersection; or any necessary construction traffic mitigation along the specified project construction haul routes. If, after the 500th Building Permit, the Flexible Mitigation Monitoring Program determines that traffic assumptions have changed significantly and a modification to the mitigation is necessary, the adjusted $6,500 traffic mitigation contribution shall be modified at the 501 st Building Permit and/or the 1201 st Building Permit to reflect the on not identified in the ECCSRTMF or the ECRAOB. C. PUBLIC II\IPROVEI\IENTS: 1) Flexible Mitigation Monitoring Program: The applicant shall work with Public Works to set up a Flexible Mitigation Monitoring Program. The program shall allow the development of up to 500 units based on these conditions of approval, plus additional units subject to review of the traffic assumptions in the EIR. a. The traffic assumption review shall take the form of a letter report summarizing the observed project development trip generation/distribution and the most current roadway improvement assumptions in East County. This new information will be compared with the EIR assumptions and a reasonable conclusion made as to whether or not traffic assumptions have changed which could result in new, or additional, significant project impacts to the surrounding road network not already identified in the EIR. 19 b. The Flexible Mitigation Monitoring Program will review the traffic assumptions no sooner than at the 400th unit and the 1100th unit, and shall be completed respectively by the 500th unit and the 1200th unit to determine if the traffic assumptions in the Environmental Impact Report are still valid (scheduling of implementation of the State Route 4 Bypass shall be considered). 1. If the initial assumptions made are still valid, the mitigation measure will remain unchanged, and the applicant will be required to comply with the conditions of approval as stated, and continue to contribute $6,500 per unit (revised annually to reflect inflation, using the State of California Construction Cost Index as published annually by Caltrans, as a reference) for additional off-site road improvements, after the first 500 units and the first 1200 units, respectively. 2. If the traffic assumptions have significantly changed for the worse and there could be new, or additional, significant project impacts not identified in the EIR, the applicant shall perform a more detailed traffic study to determine traffic impacts of the next phase of development (e.g., 501 to 1,200 or 1,200 to buildout) and recommend mitigation measures based on the new traffic assumptions. The traffic study, and the proposed traffic mitigation measures shall be subject to the review and approval of Public Works. The traffic mitiga- tion measures, if different from those identified in the EIR, may be subject to review at a public hearing. Any significant project related traffic impact which cannot qualify for the ECRAOB or other fee area will be the responsibility of the project applicant to mitigate on a fair share basis. Newly identified significant traffic impacts shall require mitigation only if the level of service does not meet the adopted traffic level of service standard. The project applicant shall arrange for mitigation of such newly identified significant and warranted traffic impacts prior to issuance of the 650th Building Permit, and again prior to issuance of the 1350th Building Permit, if necessary. 3. Impacts which were identified in the initial EIR project list will be considered satisfied for that increment of time if the initial or subsequent traffic assumption review shows impacts are insignificant (subject to the review at a public hearing if required by law), and the approval of the Zoning Administrator. (FINDINGS FOR IMPACT 436, MMA.C.) "D.57 20 C. The applicant shall submit a biannual Flexible Mitigation Monitoring Program update to review road intersections and the overall road system and to recommend potential expenditure of this project's mitigation funds commencing at the 650th Building Permit and continuing biannually with the last report issued at the 1900th Building Permit. d.
