Bailey Kenton L.Alm General Manager District Counsel ISSUE A Resolution of Application is required to request the Contra Costa LAFCO to initiate boundary reorganization proceedings. March 19, 2020 Regular Board Meeting Agenda Packet- Page 47 of 163 AMENDED AGENDA Page 2 of 94 BACKGROUND In 2014, the Town of Danville approved the "Magee Ranch" project and the Central San Board approved a Resolution of Application to initiate LAFCO proceedings to annex portions of that project site to Central San and East Bay Municipal Utility District (EBMUD). An application was submitted to LAFCO which began its consideration process. Simultaneously, a legal challenge to the Town of Danville's Environmental Impact Report (El R) and land use approvals was effective in finding the bicycle safety portion of the EI R inadequate.As a result, the LAFCO process was halted. By 2019, after a change in developers, a new EI R and a slightly revised project (now known as "Magee Preserve")were approved by the Town of Danville. That project was then subjected to a citywide referendum as Measure Y on March 3, 2020. The preliminary results indicate the measure is passing. The results require final certification by the Contra Costa County Elections Department, expected on April 2, 2020. 1 n anticipation of passage of the referendum to allow development to occur, the property owner submitted a new annexation petition to Central San staff and requested prompt Board consideration of a new Resolution of Application to LAFCO. Nine properties in Danville, associated with the Magee Preserve subdivision, need to be annexed to Central San to connect to the sanitary sewer system. Seven of those properties also need to be annexed to EBMUD to receive potable water service (see Exhibit A). These contiguous properties have been organized into one "annexation area". The proposed action is a "boundary reorganization" because it involves annexations to two or more agencies. The annexation area is within the Spheres of Influence (SOI) of both districts and the County Urban Limit Line. Staff has drafted a Resolution of Application requesting that LAFCO initiate boundary reorganization proceedings for the one annexation area. This area is described below: • Annexation Area 186-1 is comprised of nine undeveloped properties off Diablo Road.All are proposed to be annexed to Central San; seven are proposed to be annexed to EBMUD. The properties have been approved by the Town of Danville to be part of the Magee Preserve residential subdivision project. Central San staff has concluded that environmental impacts of annexing the properties in Annexation Area 186-1 to Central San and/or EBMUD are adequately addressed in the Magee Preserve EI R, certified by the Town of Danville on July 2, 2019. A copy of the E I R is available on the Town of Danville website at: https://www.danville.ca.gov/639/Magee-Preserve. Adoption of the recommended resolution will establish the Board's independent findings that the Board has reviewed and considered the EI R for Magee Preserve and agrees with findings of the Town of Danville (the Lead Agency) pertaining to a Statement of Overriding Considerations and a Mitigation Monitoring and Reporting Program. ALTERNATIVES/CONSIDERATIONS The Board could decline to initiate a boundary reorganization for these areas, which would require that the property owners apply directly to LAFCO for annexation to Central San and EBMUD. FINANCIAL IMPACTS Central San incurs costs to prepare annexation applications and pays fees to LAFCO, the County Surveyor, the County Clerk, and the State Board of Equalization for annexation processing.All annexation costs are tracked and recovered as "annexation charges." For all new annexations and reorganizations, the March 19, 2020 Regular Board Meeting Agenda Packet- Page 48 of 163 AMENDED AGENDA Page 3 of 94 property owner provides a deposit and is charged an annexation charge equal to Central San's actual administrative and related costs to process the annexation. COMMITTEE RECOMMENDATION This item was reviewed at the March 9, 2020 Real Estate, Environmental, and Planning Committee meeting and the Committee recommended Board approval. RECOMMENDED BOARD ACTION Adopt a Resolution of Application to initiate LAFCO boundary reorganization proceedings for District Annexation 186, including the finding that the Board has reviewed and considered the EI R for Magee Preserve and agrees with findings of the Town of Danville (the Lead Agency) pertaining to a Statement of Overriding Considerations and a Mitigation Monitoring and Reporting Program.

Nine unannexed properties in the Town of Danville have been organized into one "annexation area" to allow potable water and sanitary sewer service to an approved, but unconstructed, residential subdivision; 2. All of the properties are within Central San's Sphere of Influence for sewer service and EBMUD's Sphere of Influence for water; 3. All of the properties are within Contra Costa County's Urban Limit Line; 4. Upon annexation, Central San and EBMUD will assume responsibility for maintenance and operation of public facilities required to provide service to the areas proposed to be annexed; 5. Central San and EBMUD require that properties be annexed to receive utility service; and 6. No other sewer or water agency can reasonably serve these areas. WHEREAS, Contra Costa County is the only affected county (the areas proposed for annexation to Central San and EBMUD are in the Town of Danville); and no other sewering or water agencies are involved; and WHEREAS, the areas proposed for annexation to Central San and EBMUD have fewer than 12 registered voters residing therein and, therefore, are "not inhabited" under the Contra Costa County Local Agency Formation Commission's (LAFCO) criterion; and WHEREAS, if the annexation were approved, all of the provisions of the Central San District Code and EBMUD Regulations Governing Water Service to Customers would become applicable to the properties annexed; and March 19, 2020 Regular Board Meeting Agenda Packet- Page 50 of 163 AMENDED AGENDA Page 5 of 94 Central Contra Costa Sanitary District Resolution No. 2020-012 Page 2 of 3 WHEREAS, no water service can be provided to the areas to be annexed to EBMUD without the prior approval of the United States Bureau of Reclamation; and WHEREAS, staff has concluded that the environmental impacts of annexing the properties in Annexation Area 186-1 to Central San and/or EBMUD have been adequately addressed in the Magee Preserve Environmental Impact Report (EIR), certified by the Town of Danville on July 2, 2019; and WHEREAS, the project was subjected to a citywide referendum as Measure Y on the March 3, 2020 Contra Costa County ballot, and the preliminary results indicate the measure is passing, but passage requires final certification by the Contra Costa Elections Department, expected on April 2, 2020. NOW, THEREFORE, BE IT RESOLVED by the Board of Directors of Central San as follows: THAT pending final certification of approval of Measure Y, Central San staff is directed to submit this Resolution of Application requesting that LAFCO initiate boundary reorganization proceedings for the one area shown on Exhibit A as proposed Annexation Area 186-1 hereof, as authorized and in the manner required under the Cortese-Knox-Hertzberg Reorganization Act of 2000, together with a complete application package including all other required information, geographical descriptions, maps, forms, questionnaires, indemnification agreement, fees, and a mailing list of affected property owners, and of all other property owners and registered voters who reside within 300 feet of each of the proposed annexation areas; and THAT it is not the current practice of Central San or EBMUD to compel property owners to connect their properties to the public sewer or water system involuntarily; and THAT adoption of this resolution will establish Central San's Board of Directors' independent finding that the Board has reviewed and considered the EIR for Magee Preserve and agrees with findings of the Town of Danville (the Lead Agency) pertaining to a Statement of Overriding Considerations and a Mitigation Monitoring and Reporting Program (see Exhibit B). THAT Central San staff is directed to file any necessary California Environmental Quality Act (CEQA) documents with Contra Costa County.

The lawsuit further alleged that the EIR failed to adequately respond to public comments, failed to consider project alternatives that would have eliminated traffic impacts, and should have been recirculated for public comment. Finally, the lawsuit alleged that the project was inconsistent with the Town's General Plan and with other land use restrictions; and WHEREAS, the Court of Appeal rejected all allegations except the claim that the EIR did not adequately address impacts to bicycle safety. As to bicycle safety, further CEQA analysis was required before the Town considers approval of the proposed project; and WHEREAS, on April 19, 2016, the Town Council adopted Resolution No. 39-2016 setting aside and rescinding certification of the EIR and project approval; and WHEREAS, in February 2017, Davidon Homes became the project applicant; and WHEREAS, the Town of Danville prepared and circulated a Notice of Preparation (NOP) on August 31, 2017 for a 30-day review period ending on October 2, 2017, soliciting guidance from the public and interested agencies on the scope and content of the EIR; and WHEREAS, the NOP was sent to the California State Clearinghouse under Clearinghouse Number 2010112042; and WHEREAS, the Town of Danville subsequently completed a Draft Revised EIR in accordance with CEQA; and WHEREAS, on August 31, 2018, the Draft Revised EIR was released by the Town of Danville to the public and interested agencies for a 45-day public review period; and WHEREAS, the public review period ended on October 15, 2018; and WHEREAS, public comment on the Draft Revised EIR was received by the Planning Commission at the September 25, 2018 hearing; and PAGE 2 OF RESOLUTION NO. 46-2019 March 19, 2020 Regular Board Meeting Agenda Packet- Page 57 of 163 AMENDED AGENDA DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF Page 12 of 94 WHEREAS, the Town of Danville prepared a Final Revised EIR and released it to the public and interested agencies on May 16, 2019; and WHEREAS, on May 28, 2019, the Planning Commission held a public hearing on the Final Revised EIR and Project; and WHEREAS, a staff report was submitted recommending that the Danville Planning Commission recommend the Town Council certify the Final Revised EIR, approve a Statement of Overriding Considerations, adopt mitigation measures and a Mitigation Monitoring and Reporting Program and approve the development applications; and WHEREAS, at that meeting, the Planning Commission approved Resolution No. 2019- 05 recommending the Town Council certify the Final Revised EIR, approve a Statement of Overriding Considerations, adopt mitigation measures and a Mitigation Monitoring and Reporting Program, and approve the development applications; and WHEREAS, on July 2, 2019, the Town Council held a public hearing on the Final Revised EIR and Project; and WHEREAS, a staff report was submitted recommending that the Town Council certify the Final Revised EIR, approve a Statement of Overriding Considerations, adopt mitigation measures and a Mitigation Monitoring and Reporting Program and approve the development applications; and WHEREAS, after the conclusion of the public hearings on the Final Revised EIR and Project, the Town Council determined that the Revised Final EIR has been prepared in compliance with CEQA; and WHEREAS, the Town Council reviewed and considered the information contained in the Final Revised EIR and the testimony presented at the public hearings prior to making a recommendation on the Project; and WHEREAS, the Town Council finds that the Final Revised EIR reflects the Town's independent judgment and analysis; and WHEREAS, the Town Council finds that all feasible mitigation measures were considered and recommended for adoption, and to the extent a measure or alternative was not feasible, that there are specific economic, legal, social, technological, and other considerations explaining why a measure or alternative was not feasible to reduce those impacts to a less than significant level; and WHEREAS, prior to taking action, the Town Council declares that it has heard and been presented with, reviewed, and considered all of the information and data in the PAGE 3 OF RESOLUTION NO. 46-2019 March 19, 2020 Regular Board Meeting Agenda Packet- Page 58 of 163 AMENDED AGENDA DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF Page 13 of 94 administrative record, including the Final Revised EIR and other documentation relating to the Project; and WHEREAS, the Planning Commission also recommended approval of a Statement of Overriding Considerations which evaluates the benefits of the Project against its significant and potentially unavoidable traffic congestion impacts; and WHEREAS, the required CEQA Findings and Statement of Overriding Considerations are attached to this Resolution as Exhibit 1 and the required Mitigation Monitoring and Reporting Program is attached this Resolution as Exhibit 2; now, therefore, be it RESOLVED that the Danville Town Council makes the following findings: Section 1.

Section 3. The Town Council concurs with the CEQA Findings and Statement of Overriding Considerations in Exhibit 1 to this Resolution and incorporated herein by this reference and finds, that if an environmental impact remains significant and unavoidable, the benefits of the Project outweigh any potential significant and unavoidable environmental impact. The Town Council also herein incorporates the project's Mitigation Monitoring and Reporting Program attached as Exhibit 2 to this Resolution. The Town Council also concurs that there are no additional feasible alternatives or mitigation measures within its powers that would substantially lessen or avoid any significant and unavoidable impacts that may result from the Project. Section 4. The Town Council certified the Final Revised EIR, Section 5. The Town Council authorizes a Notice of Determination be filed within five working days of approval of the Project. And, be it further RESOLVED, that the Danville Town Council approve Preliminary Development Plan - Rezoning request (LEG10-0004), Major Subdivision request (SD9291 & DEV10-0071), Final Development Plan request (DEV10-0072), and Tree Removal request (TR10-0028) per the conditions contained herein, and makes the following findings in support of these actions: PAGE 4 OF RESOLUTION NO. 46-2019 March 19, 2020 Regular Board Meeting Agenda Packet- Page 59 of 163 AMENDED AGENDA DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF Page 14 of 94 FINDINGS PRELIMINARY DEVELOPMENT PLAN- REZONING 1. The rezoning of the site to P-1; Planned Unit Development District is consistent with the Town of Danville 2030 General Plan. The General Plan contains policies that encourage clustering of development on flatter portions of properties to preserve open space and natural features. 2030 General Plan Policies 1.07, 2.05, and 21.02 contain such provisions, with Policies 1.07 and 21.02 specifically identifying PUD or P-1 zoning as implementation measures. In addition, Municipal Code Section 32-63.1b provides that the P-1; Planned Unit Development District is intended to be used for properties identified as Special Concern Areas in the General Plan: the subject property is identified as a special concern area. 2. The project site is identified as a Special Concern Area in the General Plan. The text for the Special Concern Area of the Magee Ranch property (on pages 3-49 and 3-50 of the 2030 General Plan) includes the following relevant direction: • The Plan describes Diablo Road in this area as retaining "the character of a country road. The Town strongly supports retention of this character and protection of the views and vistas from the road." • ""[P]roposals which transfer the allowable number of homes to the least sensitive and obtrusive parts of the site are encouraged." • "As on the other large undeveloped hillside sites in Danville, protection of scenic slopes and ridgelines is imperative. Despite the A-2 (General Agricultural) zoning on much of the site, subdivision of this Special Concern Area into five-acre 'ranchette' sites similar to those in the Tassajara Lane/Sherburne Hills area is strongly discouraged. Such development would require grading and road construction that could substantially diminish the visual qualities of the area. Transferring allowable densities to a limited number of areas within the ranch would enable the bulk of the site to be set aside as permanent open space. This would also provide opportunities to establish park and trail connections and to preserve wildlife corridors between this area and the Sycamore Valley Open Space. P-1 zoning is the only zoning designation that permits this clustering of potential development, without creation of 5-acre "ranchettes," which the Special Concern Area language specifically discourages on the property. With clustering, the new residences would not be visible to motorists on Diablo Road. Approximately 381 acres of the project site would be set aside as permanent open space and two miles of trails would be dedicated to create connections to the Sycamore Valley Open Space. PAGE 5 OF RESOLUTION NO. 46-2019 March 19, 2020 Regular Board Meeting Agenda Packet- Page 60 of 163 AMENDED AGENDA DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF Page 15 of 94 3. The Town further finds that the rezoning for residential development is within the maximum permitted density under the existing General Plan land use designations on the property, which include Single Family-Low Density, Rural Residential, Agricultural and General Open Space. 4. The uses authorized or proposed in the land use district are compatible within the district and to uses authorized in adjacent districts. The proposed infill housing is an efficient development pattern consistent with surrounding residential subdivisions and will add to existing infrastructure that services the adjacent single family residential uses. FINAL DEVELOPMENT PLAN - MAJOR SUBDIVISION 1. The proposed subdivision is in substantial conformance with the goals and policies of the 2010 General Plan, including the requirements of Measure S. The Town's 2030 General Plan recognizes the site as an important site that merits specific direction for its development. As such, the site is designated as one of 11 Special Concern Areas within the General Plan. The Special Concern Area language includes the following provisions, which are addressed through the proposed project: • The Plan describes Diablo Road in this area as retaining "the character of a country road. The Town strongly supports retention of this character and protection of the views and vistas from the road." The project residences would be clustered at the lowest, flattest areas of the project site, where they would not be visible to motorists on Diablo Road. • The Plan provides that ""[P]roposals which transfer the allowable number of homes to the least sensitive and obtrusive parts of the site are encouraged." The clustering of homes would comply with this directive. • The Plan provides that"As on the other large undeveloped hillside sites in Danville, protection of scenic slopes and ridgelines is imperative. Despite the A-2 (General Agricultural) zoning on much of the site, subdivision of this Special Concern Area into five-acre "ranchette" sites similar to those in the Tassajara Lane/Sherburne Hills area is strongly discouraged. Such development would require grading and road construction that could substantially diminish the visual qualities of the area. Transferring allowable densities to a limited number of areas within the ranch would enable the bulk of the site to be set aside as permanent open space. This would also provide opportunities to establish park and trail connections PAGE 6 OF RESOLUTION NO. 46-2019 March 19, 2020 Regular Board Meeting Agenda Packet- Page 61 of 163 AMENDED AGENDA DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF Page 16 of 94 and to preserve wildlife corridors between this area and the Sycamore Valley Open Space." The project, through the use of P-1 zoning to cluster the permitted development, would avoid creation of "ranchette" sites, would limit grading and road construction and substantially preserve the visual quality of the area. The clustering of the project would also permanently preserve 381 acres, or approximately 93% of the site as open space, which would include trail connections to the Sycamore Valley Open Space, provision of easements necessary to create a bicycle/pedestrian trail parallel to Diablo Road, and preservation of wildlife corridors through the site. 2. The design of the proposed subdivision is in conformance with the P-1; Planned Unit Development District since the subject P-1; Planned Unit Development District is customized to the subject Development Plan. The P-1; Planned Unit Development District is an appropriate zoning designation for infill projects and lands designated as Special Concern Areas in the General Plan. Additional detailed findings regarding P-1 zoning consistency can be found under Preliminary Development Plan- Rezoning above. 3. The design of the subdivision and the type of associated improvements will not likely cause serious public health problems, because water and sanitary facilities services will be available to the new parcels. 4. The site of the subdivision is physically suitable for the proposed density of development. The proposed development of 69 lots on the 410 +/- acre site falls within the allowable maximum density range of up to 78 units, consistent with the site's Danville 2030 General Plan land use designations of Residential -Single Family -Low Density, Rural Residential, Agricultural and General Open Space. With respect to density on the portions of the site designated as "Agricultural" in the 2030 General Plan, the General Plan provides the following: "Because properties with this designation are bound by Williamson Act contract to remain in agricultural uses, a density range is not applicable. In the event that Williamson Act contracts are not renewed, continued agricultural use is encouraged and the underlying zoning density (one unit per 20 acres or one unit per five acres) would apply upon the contract expiration." The portions of the site designated as Agricultural are no longer bound by Williamson Act contract. In such situations, the Town's practice (and that of Contra Costa County, prior to the Town's incorporation in 1982) was to zone lands to A-4 (20 acre minimum) upon execution of a Williamson Act contract, PAGE 7 OF RESOLUTION NO. 46-2019 March 19, 2020 Regular Board Meeting Agenda Packet- Page 62 of 163 AMENDED AGENDA DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF Page 17 of 94 regardless of the size or prior zoning of the property. The purpose of this A-4 zoning designation is to show that the property is under a Williamson Act contract. For example, the Town rezoned the "Borel" property (APN 218-090- 031) from P-1 to A-4 upon execution of a Williamson Act contract, despite the entire parcel being only 17 acres. Under the A-4 zoning designation one home per 20 acres is allowed. Upon expiration of a Williamson Act contract, the General Plan dictates that the Town apply the "underlying" zoning, which has been the zoning in effect prior to entering into the contract. This reflects the intent to place the property in the position it held prior to entering into the contract, neither increasing nor decreasing the property's development potential. This practice was previously applied by the Town with respect to Assessors Parcels 202-100-017, -018, and -019 on the subject property. In February 1986, the Town approved a Williamson Act contract for these parcels and at the same time adopted an ordinance rezoning them from A-2 to A-4. In March 1988, after discovery that the contract had never been properly executed, the property owner requested, and the Town approved, an ordinance rezoning the property back to the prior designation of A-2. The property owner in this case did not apply to rezone the property after the Williamson Act contract expired. However, in determining potential density for purposes of this application, the Town used the underlying zoning of A-2 (with the corresponding maximum development density of one unit per five acres) as provided for in the General Plan and consistent with prior applications, including the Elworthy Ranch project approved by the Town in 2008 under the approval granted for Preliminary Development Plan - Rezoning request PUD 2005-02. 5. The design of the proposed subdivision and improvements are not likely to cause substantial environmental damage or subsequently injure fish or wildlife or their habitat. The Revised Environmental Impact Report prepared for the project found that, with implementation of recommended mitigation measures, the project would have no significant negative impacts on the wildlife on site, including California Red Legged Frogs, wetlands, trees and plant life. 6. The design of the proposed subdivision and proposed improvements will not conflict with easements, acquired by the public at large, for access through or use of property within the proposed subdivision. There are currently no existing public easements for access through or use of the subdivision. Through project conditions of approval, the subdivision will offer new easements for public access. PAGE 8 OF RESOLUTION NO. 46-2019 March 19, 2020 Regular Board Meeting Agenda Packet- Page 63 of 163 AMENDED AGENDA DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF Page 18 of 94 7. The project will not cause on-site flooding or add to existing downstream flooding as detailed in the Hydraulic Report prepared for the project by ENGEO, Inc. and as concurred with by the Contra Costa County Flood Control and Water Conservation District. TREE REMOVAL PERMIT The project as proposed would preserve 272 trees out of the 321 surveyed trees and many other trees located throughout the site, and remove 49 trees. Of the 49 trees to be removed, seven are designated as protected trees under the Town's Tree Preservation Ordinance. In addition, to construct roadway improvements at and near the intersection of Diablo Road/Green Valley Road/McCauley Road, the project would remove 18 trees, including eight protected trees. The findings below address only the 15 trees designated as protected under the Town's Tree Preservation Ordinance. The EIR for the project analyzes the potential environmental impacts of removing all trees, whether or not they are designated as protected. 1. Necessi . The primary reason for removal of the 67 trees, including 15 Town- protected trees, is that preservation of those trees would be inconsistent with the proposed residential development of the property, including the creation of a new roadway to access the main project area, including a new creek crossing, to be located east of Jillian Way, and the widening of the Diablo Road/Green Valley Road/McCauley Road intersection to the south to improve the function of that intersection. 2. Erosion/surface water flow. Removal of the 15 Town-protected trees and 67 total trees would not cause significant soil erosion or cause a significant diversion or increase in the flow of surface water. 3. Visual effects. With respect to other trees in the area, the project site contains a significant number of additional trees, including Town-protected Oak trees that would not be removed for the project. In addition, the project proponent will be required to replace all Town-protected trees to be removed with approved species "of a cumulative number and diameter necessary to equal the diameter of the tree(s) which are approved for removal" in accordance with the Town's Tree Preservation Ordinance. Tree replacement will be conducted in accordance with the Towri s requirements, including planting a mixture of small and large box trees to meet the cumulative diameter number of the removed trees. The project proponent will also be required to replace all non-ordinance-size trees (i.e., trees less than 10 inches in diameter for single-trunk trees or less than 20 inches in diameter for multi-trunk trees) at a replacement-to-removal ratio of 1:1.

Prior to the start of construction, the project proponent shall retain a qualified biologist to train all construction personnel regarding habitat sensitivity, identification of special status species, and required practices. b. Prior to the start of construction, the project proponent shall retain a qualified biologist to conduct pre-construction surveys to ensure that CRLF are absent from the construction area. If CRLF are present, a qualified biologist possessing all necessary permits shall relocate them or they shall be allowed to move out of the construction area on their own. C. Immediately following the pre-construction surveys and a determination that CRLF are not present in the construction zone, the construction zone shall be cleared and silt fencing erected and maintained around construction zones to prevent CRLF from moving into these areas. d. The project proponent shall retain a qualified biological monitor to be present onsite during times of construction within the riparian habitat of East Branch Green Valley Creek to ensure no CRLF are harmed, injured, or killed during project buildout. 2. The project would impact approximately 0.3 acres of moderate-quality riparian habitat resulting from construction of the vehicular bridges across East Branch Green Valley Creek. The project shall replace the lost value of this impact by restoring the impacted riparian habitat at a minimum 1:1 replacement-to-loss ratio. (Final mitigation amounts will be based on actual impacts to be determined during the design phase.) This shall be accomplished by restoring riparian habitat at the four following locations: PAGE 22 OF RESOLUTION NO. 46-2019 March 19, 2020 Regular Board Meeting Agenda Packet- Page 77 of 163 AMENDED AGENDA DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF Page 32 of 94 a. The existing wet crossing and asphalt near the panhandle (i.e., where the new bridge is to be constructed) shall be removed. The silt and sediment buildup behind and adjacent to the wet crossing and asphalt shall also be removed and the creek bed shall be lowered to restore the natural flow of this portion of the creek. b. The existing crossing from San Andreas Drive shall be removed and the creek restored in this area. C. The two existing cattle grates on Magee West near the existing culverts shall be removed. One of these is causing sediment build up and adversely impacting the creek. The natural flow of this channel shall be restored back to its original condition prior to the original installation of the grates. d. The riparian corridor along the East Branch of Green Valley Creek will be enhanced with suitable planting and placement of riparian vegetation along the proposed trail on Magee East. Approximately 2 acres along East Branch Green Valley Creek between the creek and the trail is available to accommodate the minimum 0.3 acres of riparian enhancement plantings. The enhancement area shall be planted with native species appropriate for the corridor. 3. The project would impact approximately 0.5 acres of jurisdictional waters that are of a degraded quality and marginal value for the CRLF. The project shall replace the lost functions and value of this impact to aquatic habitats at a minimum of 1:1 replacement-to-loss acreage ratio. The final mitigation amounts will be based on actual impacts to be determined during the design phase. Habitat replacement via creation of and/or enhancements to existing waters shall occur onsite. Onsite lands proposed to be preserved as open space are within the same watershed as the offsite detention basin known to support breeding CRLF and are expected to fully accommodate creation of and/or enhancements to aquatic habitats that would be of substantially higher value to CRLF than the impacted waters. Compensation for impacts to jurisdictional waters to benefit the CRLF will include all of the aforementioned components discussed under "Compensation: riparian restoration," along with improving the wetland character of the onsite stock pond and enhancing the associated riparian habitat between the stock pond and the detention basin. (Refer also to mitigation measures 4.4-13 and 4.4-14 below for impacts to jurisdictional waters.) 4. The project proposes to preserve approximately 381 acres of the project site as open space. Areas to be preserved would be placed under a conservation easement or deed restriction to prohibit construction and preserve conservation value. The project proposes to create a geologic hazard abatement district (GHAD) to provide suitable funding for management and long-term maintenance of the site. Upland PAGE 23 OF RESOLUTION NO. 46-2019 March 19, 2020 Regular Board Meeting Agenda Packet- Page 78 of 163 AMENDED AGENDA DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF Page 33 of 94 habitats shall be managed via a long-term management plan to maintain the quality of the habitat for the movement and dispersal of CRLF. Prior to construction, the project proponent shall retain a qualified biologist to prepare an open space management plan for the explicit purpose of managing and monitoring the proposed open space area. This plan shall be submitted to the Town of Danville for review and approval prior to issuance of grading permits. At a minimum this plan shall include the following components: a. Identify the location of the restoration efforts for replacing jurisdictional waters and riparian habitats. The replacement ratio for both habitats will be at a minimum of a 1:1 ratio. b. Identify the approaches to be used, including the extent that the onsite stock pond be expanded, reconfiguring of the pond bottom and increase in depth, and providing evidence that sufficient water budget exist for any proposed enhancement. C. Identify a suitable planting regime for restoring wetland and riparian habitats. d. Identify success criteria for monitoring both the wetland and riparian habitats that are consistent with similar habitats regionally. e. Monitor restored wetland habitats for at least five years and restored riparian habitats for 10 years. f. Define and identify the GHAD maintenance and management activities to manage the open space habitats to meet the stated goals of support habitat characteristics suitable for the CRLF. This would include suitable fencing so as to control access, limited cattle grazing or other procedures to manage grass height and forage production at levels that benefit the CRLF, and removal of trash. g. Define the financial mechanism for the GHAD to manage the open space into perpetuity. 5. Prior to the start of construction, the project proponent shall retain a qualified biologist to train construction personnel regarding habitat sensitivity, identification of special status species, and required practices. 6. Prior to the start of construction within the East Branch Green Valley Creek riparian area, the project proponent shall retain a qualified biologist to conduct pre-construction surveys to ensure that western pond turtles are absent from the construction area. If western pond turtles are present, a qualified biologist possessing all necessary permits shall be retained to relocate them. PAGE 24 OF RESOLUTION NO. 46-2019 March 19, 2020 Regular Board Meeting Agenda Packet- Page 79 of 163 AMENDED AGENDA DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF Page 34 of 94 7. If western pond turtles are found to be absent from the construction zone, immediately following the pre-construction surveys the project proponent shall clear the construction zone and install/maintain silt fencing around the construction zone to prevent western pond turtles from entering these areas. 8. During construction within the East Branch Green Valley Creek riparian area, the project proponent shall retain a biological monitor to be present onsite during times of construction to ensure that turtles are not harmed, injured, or killed. 9. To the maximum extent practicable, the project proponent shall remove trees during the non-breeding season (September 1 through January 31). If it is not possible to avoid tree removal and associated disturbances during the breeding season (February 1 through August 31), the project proponent shall retain a qualified biologist to conduct a pre-construction survey for tree-nesting raptors and other tree- or ground-nesting migratory birds in all trees or other areas of potential nesting habitat within the construction footprint and 250 feet of the footprint, if such disturbance would occur during the breeding season. This survey shall be conducted no more than 14 days prior to the initiation of demolition/construction activities during the early part of the breeding season (February through April) and no more than 30 days prior to the initiation of these activities during the late part of the breeding season (May through August). If nesting raptors or migratory birds are detected on the site during the survey, a suitable construction free buffer shall be established around all active nests. The precise dimension of the buffer (a minimum of 150 feet up to a maximum of 250 feet) shall be determined at that time and may vary depending on location and species. Buffers shall remain in place for the duration of the breeding season or until it has been confirmed by a qualified biologist that all chicks have fledged and are independent of their parents. Pre-construction surveys during the non- breeding season are not necessary, as the birds are expected to abandon their roosts during construction activities. 10. In order to avoid impacts to active burrowing owl nests, the project proponent shall retain a qualified biologist to conduct pre-construction surveys for burrowing owls within the construction footprint and within 250 feet of the footprint no more than 30 days prior to the onset of ground disturbance. These surveys shall be conducted in a manner consistent with the CDFG's burrowing owl survey methods (CDFG 2012b). If pre-construction surveys determine that burrowing owls occupy the site during the non-breeding season (September 1 through January 31), then a passive relocation effort (e.g., blocking burrows with one-way doors and leaving them in place for a minimum of three days) may be used to ensure that the owls are not harmed or injured during construction. Once it has been determined that owls have vacated the site, the burrows can be collapsed, and ground disturbance can proceed. If burrowing owls are detected within the construction footprint or immediately adjacent lands (i.e., within 250 PAGE 25 OF RESOLUTION NO. 46-2019 March 19, 2020 Regular Board Meeting Agenda Packet- Page 80 of 163 AMENDED AGENDA DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF Page 35 of 94 feet of the footprint) during the breeding season (February 1 through August 31), a construction free buffer of 250 feet shall be established around all active owl nests. The buffer area should be enclosed with temporary fencing, and construction equipment and workers may not enter the enclosed setback areas. Buffers must remain in place for the duration of the breeding season or until it has been confirmed by a qualified biologist that all chicks have fledged and are independent of their parents. After the breeding season, passive relocation of any remaining owls may take place as described above. 11. Pre-construction surveys conducted for burrowing owls shall also be used to determine the presence or absence of badgers in the development footprint. If an active badger den is identified during pre-construction surveys within or immediately adjacent to the construction envelope, the project contractor shall establish a construction free buffer around the den of up to 300 feet or a distance specified by the resource agencies (i.e., CDFG). Because badgers are known to use multiple burrows in a breeding burrow complex, the project contractor shall retain a biological monitor during construction activities to ensure the buffer is adequate to avoid direct impacts to individuals or nest abandonment. The monitor shall be present onsite until it is determined that young are of an independent age and construction activities would not harm individual badgers. Once it has been determined that badgers have vacated the site, the burrows can be collapsed or excavated, and ground disturbance can proceed. 12. The project proponent shall replace wetland and riparian habitat at a 1:1 replacement-to-loss ratio. It is expected that all compensation measures can be accommodated within the 381 acres of the site proposed as open space. Prior to issuance of a grading permit, the project proponent shall retain a qualified biologist to prepare an onsite habitat mitigation and monitoring plan (HMMP) that includes both an aquatic habitat restoration plan and a riparian habitat restoration plan. The HMMP would specifically address the wetland and riparian habitats and is separate from the Open Space Management Plan identified in Mitigation 4.4-4, although there may be some overlap. The HMMP shall include the following components, at a minimum: a. Define the location of all restoration/creation activities; b. Provide evidence of a suitable water budget to support any created wetland and riparian habitats; C. Identify the species, amount, and location of plants to be installed; d. Identify the time of year for planting and method for supplemental watering during the establishment period, PAGE 26 OF RESOLUTION NO. 46-2019 March 19, 2020 Regular Board Meeting Agenda Packet- Page 81 of 163 AMENDED AGENDA DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF Page 36 of 94 e. Identify the monitoring period, which should be not less than 5 years for wetland restoration and not less than 10 years for riparian restoration, defines success criteria that will be required for the wetland restoration to be deemed a success, f. Identify adaptive management procedures that include (but are not limited to) measures to address colonization by invasive species, unexpected lack Of water, excessive foraging of installed wetland plants by native wildlife, and similar; g. Define management and maintenance activities (weeding of invasives, providing for supplemental water, repairing of water delivery systems) of the proposed GHAD; and h. Provide for assurance in funding the monitoring and ensuring that the created wetland and riparian habitats fall within lands to be preserved and managed into perpetuity. Confirm that the proposed GHAD will meet these responsibilities. 13. The project proponent shall comply with all state and federal regulations related to construction work that will impact aquatic habitats occurring on the site. Prior to construction, the project proponent shall obtain a Section 404 Clean Water Act permit from the USACE, Section 401 Water Quality Certification from the RWQCB, and/or Section 1600 Streambed Alteration Agreement from the CDFG, and submit proof of such documentation to the Town of Danville. 14. Prior to issuance of a grading permit, a tree preservation plan shall be prepared for all trees to be retained that identifies all protection and mitigation measures to be taken and includes the tree preservation guidelines by HortScience in their tree report(s). These measures shall remain in place for the duration of construction activities at the project site. 15. Upon completion of construction, the project proponent shall replace all ordinance-size trees to be removed with approved species "of a cumulative number and diameter necessary to equal the diameter of the tree(s) which are approved for removal" in accordance with the Town's tree ordinance. Tree removal shall be conducted in accordance with the Town's requirements, including planting a mixture of small and large box trees to meet the cumulative diameter number of the removed trees. The project proponent shall replace all non-ordinance-size trees (i.e., trees less than 10 inches in diameter for single- trunk trees or less than 20 inches in diameter for multi-trunk trees) at a replacement-to-removal ratio of 1:1. To the maximum extent practicable, all native trees that are removed shall be replaced with like species. All non-native trees that are removed shall be replaced with species that are known to occur naturally within similar habitats in the region. PAGE 27 OF RESOLUTION NO. 46-2019 March 19, 2020 Regular Board Meeting Agenda Packet- Page 82 of 163 AMENDED AGENDA DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF Page 37 of 94 16. Prior to construction, the project proponent must retain a qualified arborist to develop a monitoring plan for replacement trees (outside the riparian habitat) and submit it to the Town of Danville during the permit process. The basic components of the monitoring plan shall include final success criteria, specific performance criteria, monitoring methods, data analysis, monitoring schedule, contingency/remedial measures, and reporting requirements. 17. For tree removal necessitated by the improvements to the Diablo Road/Green Valley Road intersection, the project shall implement Conditions of Approval 14- 16 above, as applicable. F. GRADING * 1. Any grading on adjacent properties will require prior written approval of those property owners affected. * 2. At least one week prior to commencement of grading, the applicant shall post the site and mail to the owners of property within 300 feet of the exterior boundary of the project site, to the homeowner associations of nearby residential projects and to the Town of Danville Development Services Department, a notice that construction work will commence.

Prior to the approval of the Improvement Plans, Danville Transportation Division shall review and approve the location, type and design of the speed control device, as well as the locations and number of signage and striping. 10. If approved by Contra Costa County, install a traffic signal at the intersection of Diablo Road/Blackhawk Road and Mt. Diablo Scenic Boulevard at the applicant's expense. The traffic signal shall be installed prior to occupancy of the 35th residence in the project, or within one year of the County's final approval of the intersection improvement plan, whichever comes last. 11. The project proponent shall modify the roadway striping along McCauley Road between the intersection and approximately 350 feet south of Diablo Road/Green Valley Road. The modified roadway striping shall substantially conform to the following: a) reconfigure the existing 17-foot southbound through lane to a 10-foot shoulder and a 12-foot through lane; b) replace the existing 3-foot double-double yellow centerlines with a single double yellow center-line; c) maintain the existing 10-foot northbound left turn lane while shifting it two feet toward the easterly curb line; d) reduce the existing 16-foot northbound through/right turn lane to 13 feet; and e) transition existing downstream (to the south) centerline/left turn lane on McCauley Road accordingly to accommodate the new configuration, as illustrated at page 4.3-44 of the Draft REIR. This improvement shall be completed prior to issuance of building permits for any of the three residences just east of McCauley Road. 12. The project proponent shall install a new pedestrian crossing and supplemental pedestrian-actuated warning system at the project main entrance on Blackhawk Road. The crossing shall physically connect the project's pedestrian traffic to the existing paved pathway located along the north side of Blackhawk Road. The project proponent will be required to submit improvement plans to Contra Costa County for review and approval. If Contra Costa County elects not to maintain the PAGE 34 OF RESOLUTION NO. 46-2019 March 19, 2020 Regular Board Meeting Agenda Packet- Page 89 of 163 AMENDED AGENDA DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF Page 44 of 94 selected pedestrian safety improvement, then said maintenance shall be provided by the project Homeowner's Association. 13. The applicant shall apply for a Large Road Encroachment Permit from Contra Costa County Public Works for the construction of the intersection of Appaloosa Street with Blackhawk Road. The applicant shall contact the Engineering Services Division of the County Public Works Department (925-313-2000) to process a Road Acceptance Agreement along with the review of plans associated with the encroachment permit. The application shall include the applicant's proposal to close off Jillian Way to create a single point of ingress/egress to Blackhawk Road. 14. No construction work requiring closure or detour from any portion of Diablo Road or Blackhawk Road shall be performed during the morning or evening commute hours, or on weekends or holidays. Commute hours shall be assumed to be between the hours of 6:00 a.m. and 10:00 a.m. and between 3:00 p.m. and 7:00 p.m. 15. According to the Final Map for Subdivision 7985 (recorded on June 3, 1999 in Book 392 of Map at Pages 47-48), temporary right-of-way was granted to the Town across a portion of Lot 6 in order to provide the residents of Jillian Way access to Blackhawk Road. A note on the map indicates that the Town will abandon this right-of-way and give fee title back to Lot 6 when alternative access is provided through the adjoining property to the east. Since the applicant's development project seeks to grant alternative access to the Jillian Way residents and seeks to close-off the access through Lot 6 to Blackhawk Road, the applicant shall provide the Town with a legal description and plat map to effectuate the abandonment. 16. The applicant shall establish a fund (with a preset amount of $30,000) that shall be used to subsidize TRAFFIX use or other transportation programs. 17. The applicant shall make an offer of dedication to the Town of approximately 50 feet of frontage along the project site's Diablo Road frontage from the Diablo Road/McCauley Road intersection easterly to the intersection of the project's Emergency Vehicle Access/pedestrian trails and Diablo Road (approximately 7,200 linear feet). The exact width of the dedication shall be subject to review and approval by the City Engineer prior to recordation of the Final Map. PAGE 35 OF RESOLUTION NO. 46-2019 March 19, 2020 Regular Board Meeting Agenda Packet- Page 90 of 163 AMENDED AGENDA DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF Page 45 of 94 18. The project shall be required to install two solar powered radar signs along the project site's Diablo Road frontage. The exact location shall be determined by the Town prior to recordation of the final map. 19. The improvements for the Diablo Road/Green Valley Road/McCauley Road intersection, as shown on the approved project plans, shall be completed prior to occupancy of the 18th residence in the development. H. INFRASTRUCTURE * 1. Domestic water supply shall be from an existing public water system.

Drainage facilities and easements shall be provided to the satisfaction of the City Engineer and/or the Chief Engineer of the Contra Costa County Flood Control &Water Conservation District. 4. In order to reduce wind and water erosion on the project site, an erosion control plan and Storm Water Pollution Prevention Plan (SWPPP) shall be prepared for the site preparation, construction, and post-construction periods (see mitigation measure 4.8-1.). The project shall prepare an erosion control plan in accordance with the Town's Erosion Control Ordinance. The project proponent shall implement the following measures, where appropriate, to control erosion: 1) keep construction machinery Off of established vegetation as much as possible, especially the vegetation on the upwind side of the construction site; 2) establish specific access routes at the planning phase of the project, and limits of grading prior to development, which should be strictly observed, 3) utilize mechanical measures (i.e., walls from sand bags and/or wooden slat or fabric fences) to reduce sand movement; 4) immediate re-vegetation (plus the use of temporary stabilizing sprays), to keep sand movement to a minimum; and 5)for larger-scale construction,fabric or wooden slat fences should be placed around the construction location to reduce sand movement. This erosion control plan shall be submitted to the Town of Danville for review and approval prior to issuance of a grading permit. * 5.

Section 1.2 provides a description of the public review process that has led decision makers to their conclusions regarding the Magee Preserve Project (Project). Section 2.0 presents the purpose and background of the Project,including a project description, to provide the context upon which these Findings are based. Section 3.0 presents the substantiation for certification of the EIR. The Findings in Section 4.0 relate to those impacts that have been determined to be less than significant. Section 5.0 contains Find- ings for impacts have been identified as potentially significant impacts. Section 6.0 contains the Findings for cumulative impacts and Section 7.0 contains Findings regarding monitoring of mitigation measures. Section 8.0 contains Findings regarding the alternatives to the Project. Section 9.0 contains Findings for growth-inducing impacts. The Statement of Overriding Considerations in contained in Section II. 1.1 California Environmental Quality Act The California Environmental Quality Act ("CEQA") (Public Resources Code §21000-21177) and the State CEQA Guidelines (Cal. Code of Regulations, Title 14, §15000-15387) require that specific findings be made if a lead agency decides to approve a project which will have significant impacts. 521081 of the California Public Resources Code states: [N]o public agency shall approve or carry out a project for which an Environmental Impact Report has been cer- tified which identifies one or more significant effects on the environment that would occur if the project is ap- proved or carried out unless both of the following occur: (a) The public agency makes one,or more,of the following findings with respect to each significant effect: (1) Changes or alterations have been required in, or incorporated into, the project which mitigate or avoid the significant effects on the environment. (2) Those changes or alterations are within the responsibility and jurisdiction of another public agency and have been,or can and should be,adopted by that other agency. (3) Specific economic,legal, social,technological,or other considerations. Including considerations for the provision of employment opportunities for highly trained workers,make infeasible the mitiga- tion measures or alternatives identified in the environmental impact report. (b) With respect to significant effects which were subject to a finding under paragraph (3) of subdivision (a), the public agency finds that specific overriding economic,legal, social, technological, or other benefits of the project outweigh the significant effects on the environment. The Revised Environmental Impact Report ("REIR") for the Project (State Clearinghouse No. 2010112042) identifies significant or potentially significant environmental impacts which, prior to mitigation, may occur as a result of imple- mentation of the Project.Thus,in accordance with the provisions of CEQA,the Town of Danville,as the"lead agency" hereby adopts these Findings. 1.2 Environmental Review Process In conformance with CEQA, the Town of Danville conducted an environmental review process on the Project. The environmental review process included the following: I-1 144459224.1 March 19, 2020 Regular Board Meeting Agenda Packet- Page 101 of 163 AMENDED AGENDA DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF Page 56 of 94 ♦ Relationship to 2013 EIR: In June 2013, the Town certified an Environmental Impact Report for and approved SummerHill Homes' applica- tions for a 69-lot residential project on the Project site. SOS-Danville Group then filed suit to challenge the project approvals,alleging that the Environmental Impact Report for the project inadequately addressed impacts to traffic, bicycle safety, pedestrian safety, California red-legged frog, emergency access, safe evacuation, flooding, erosion, and siltation. The lawsuit further alleged that the 2013 EIR filed to adequately respond to public comments, failed to consider project alternatives that would have eliminated traffic impacts, and should have been recirculated for public comment. Finally, the lawsuit alleged that the project was inconsistent with the Town's General Plan and with other land use restrictions and that a public vote under the Town's Measure S was required before the project could be approved. The only claim that prevailed in the litigation was that the EIR did not adequately address impacts to bicycle safety. As to bicycle safety,the Court of Appeal required further CEQA analysis before the Town could make a decision whether to re-approve the project. As required by the final judgment in the litigation, the Town rescinded its ap- provals of the 2013 project pending further CEQA review on this issue. In February 2017,Davidon Homes became the project applicant. Davidon Homes revised the Project proposal to reduce developed area and correspondingly increase protected open space by approximately nine acres; to replace, rather than remove,the existing corral on the site;to include an electric vehicle charging station on each residential lot;and to include as Project elements certain requirements that had been imposed as mitigation measures in 2013. In August 2017,the Town issued a Notice of Preparation of a Revised Draft Environmental Impact Report and an Initial Study/CEQA Environmental Checklist ("NOP/Checklist") that compared the impacts of the Project to the impacts of the project as analyzed in the 2013 EIR. The NOP/Checklist stated the Town's determination that the Revised Draft EIR would address not only bicycle safety,but also update the 2013 EIR's analyses of other aspects of transportation and circulation, as well as air quality,greenhouse gas emissions,noise, and energy. As to all other environmental topics, the NOP/Checklist explained that the analysis in the 2013 EIR remained applicable to the Project. ♦ Scoping Process: The Town of Danville prepared the NOP for the Project in accordance with§15082 of the CEQA Guidelines.The NOP was distributed for public review on August 29,2017. Environmental issues raised by comments received in response to the NOP during its 30-day public review period (August 31 - October 2,2018)were considered for in- clusion in the Draft REIR. Public and agency comments received on the NOP were reviewed and addressed in the Draft REIR. ♦ Preparation of a Draft REIR by the Town of Danville: The Draft REIR was distributed to Responsible Agencies, other affected agencies,and interested parties. The No- tice of Completion (NOC) of the Draft EIR was distributed as required by CEQA,including publication of notice in the San Ramon Valley Times on August_2018. The 45-day public review period began on August 31,2018 and ended on October 15, 2018. During the public review period, the Draft REIR, including appendices,was made available and circulated for public review. ♦ Public Hearing on the Draft REIR: A public hearing was held by the Town of Danville Planning Commission on September 25,2018 to receive public comment on the Draft REIR. The Town responded to all environmental questions submitted verbally or in writing in the Final REIR. r-2 1444592241 March 19, 2020 Regular Board Meeting Agenda Packet- Page 102 of 163 AMENDED AGENDA DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF Page 57 of 94 ♦ Preparation of the Final REIR: Pursuant to Public Resources Code §21092.5, the Town prepared the Final REIR in response to comments on the Draft REIR. The Final REIR contains the following: refinements and clarifications to the Draft REIR; written comments received on the Draft REIR; responses to those comments; and testimony presented to the Planning Commission and responses thereto. The Final REIR was issued on May 16,2019. 2.0 PURPOSE AND BACKGROUND 2.1 Description of the Project The Project evaluated in the Draft REIR consists of development of a 410 acre property currently referred to as Magee Ranches (Magee West and Magee East)in the Town of Danville. Magee West extends east of McCauley road just south of the intersection of Diablo/McCauley Road and South of Diablo/Blackhawk Road east of the Diablo McCauley inter- section. Magee East lies south of Diablo/Blackhawk Road,roughly between Jillian Way and Creekledge Court. The Project evaluated in the Draft REIR proposes 69 single family lots,with three lots on Magee West and 63 lots on Magee East. The Project proposes to locate the lots, along with road rights-of-way and privately-operated open space, on approximately 29 acres of the flatter portions of the site, avoiding the steeper slopes and ridges. The remaining± 381 acres of the site would be.preserved as new permanent open space. A minimum of 10% of the homes would in- clude second dwelling units in accordance with the Town's Inclusionary Housing Ordinance.The Project would provide a publicly accessible trail along Green Valley Creek and would dedicate land to the Town for the Town's potential trail along the south side of Diablo Road. The overall objectives of the Project are to: ♦ Develop a residential project that is consistent with the Town of Danville Agricultural, General Open Space,Rural Residential, and Single Family-Low Density General Plan Land use designations for the site as well as the General Plan's Magee Ranch Special Concern Area language, ♦ Provide 69 residential lots,including 66 home sites at the east end of the site south of Blackhawk Road and 3 homes home sites near the southeast corner of the Diablo Road/McCauley road intersection, ♦ Design the project to cluster development on the lower portions of the site to minimize visual impacts and limit dis- turbance on the property, ♦ Provide for a minimum of 10% of the 69 lots to include a second dwelling unit ("casita") to satisfy the Town's af- fordable housing requirements, ♦ Preserve-approximately 381 acres of the project site as permanent open space,and ♦ Preserve significant features of scenic hillsides and major ridgeline areas. The objectives have been updated from those stated in the 2013 Final EIR to reflect the Project's increase in permanent open space from 372 to 381 acres. 2.2 Purpose of the REIR Pursuant to CEQA,Public Resources Code sections 21000 et seq.,and the CEQA Guidelines,California Code of Regu- lations, Title 14, 515000 et seq., the Town agency prepared the REIR to analyze the Project's potential environmental effects. The Draft REIR was circulated for public review for a 45-day period beginning August 31,2018 and ending on October 15, 2018. Responses to comments were prepared and are contained in the Final REIR. The REIR includes t-3 1444592241 March 19, 2020 Regular Board Meeting Agenda Packet- Page 103 of 163 AMENDED AGENDA DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF Page 58 of 94 Appendix A,the NOP/Checklist,which examined the Project for potential changes in impacts since the 2013 EIR and determined that additional analyses would be prepared not only as to bicycle safety, but also as to Air Quali- ty/Greenhouse Gas,Noise,Transportation and Circulation issues other than bicycle safety,and Energy. 2.3 Description of the Record For purposes of CEQA and these Findings,the record before the Town includes,without limitation,the following: 1) ' The NOP/Checklist for the REIR; 2) The Draft REIR and all appendices to the Draft REIR; 3) The Final REIR and all appendices to the Final REIR; 4) All notices,staff reports,and presentation materials related to the Project, 5) All studies and reports conducted for the Project which are contained in,or referenced by, staff reports,the Draft REIR,or the Final REIR; 6) All public reports and documents related to the Project prepared for the Town and other agencies; 7) All documentary and oral evidence received and reviewed at public hearings and workshops and all tran- scripts and minutes of those hearings related to the Project,the Draft REIR,and the Final REIR; 8) For documentary'and informational purposes, all locally-adopted land-use plans and ordinances, including, without limitation, specific plans and ordinances, master plans together with environmental review docu- ments,findings,mitigation monitoring programs and other documentation relevant to planned growth in the area; 9) Any proposed decisions or findings or statements submitted to the decision makers by staff or others; 10) Documentation of the final decisions,including the REIR, as well as all documents relied on in the Town's CEQA Findings and statement of overriding considerations; 11) The Record of Proceedings for the 2013 EIR;and 12) Any additional items not included above,if they are required by law. 2.4 Discretionary Actions The discretionary action for the Project involves the following approval by the Danville Town Council: 1) Certification of the REIR for the Project 2) Approval of: ■ Preliminary Development Plan and Final Development Plan to rezone approximately 410 acres from A-4,A-2 and P-1,to a new P-1 (LEG 10-0004,DEV 10-0071,DEV 10-0072) ("rezoning"); • Vesting Tentative Map to create 69 single family lots (SD 9291) ("VTM");and • Tree Removal Permit(TR-10-0028) ("Tree Permit"). I-4 144459224.1 March 19, 2020 Regular Board Meeting Agenda Packet- Page 104 of 163 AMENDED AGENDA DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF Page 59 of 94 These Findings are made by the Planning Commission pursuant to X15091 of the CEQA Guidelines. The Planning Coimnission is also recommending the adoption of a Statement of Overriding Considerations pursuant to 515093 of the CEQA Guidelines. 3.0 GENERAL FINDINGS 3.1 Terminology of Findings CEQA Guidelines §15091 requires that, for each significant environmental effect identified in an EIR for a proposed project, the approving agency must issue a written finding reaching one or more of three allowable conclusions. The first is that"[c]hanges or alterations have been required in,or incorporated into,the project which avoid or substantially lessen the significant environmental effect as identified in the [Final] EIR." The second potential finding is that"[s]uch changes or alterations are within the responsibility and jurisdiction of another public agency and not the agency making the finding. Such changes have been adopted by such other agency or can and should be adopted by such other agen- cy." The third permissible conclusion is that "[s]pecific economic, social, or other considerations make infeasible the mitigation measures or project alternatives identified in the final EIR." For purposes of these Findings, the term "mitigation measures" shall constitute the "changes or alterations" discussed above. The term"avoid or substantially lessen"will refer to the effectiveness of one or more of the mitigation measures or alternatives to reduce an otherwise significant environmental effect to a less-than-significant level. In the process of adopting any mitigation, the Town would also make decisions on whether each mitigation measure proposed in the Draft REIR is feasible or infeasible. Pursuant to the CEQA Guidelines, "feasible means capable of being accomplished in a successful manner within a reasonable period of time, taking into account economic, environ- mental,legal, social, and technological factors." (CEQA Guidelines, §15364.) When the Town finds a measure is not feasible,evidence for its decision will be provided. 3.2 Certification of Environmental Impact Report and Adoption of Findings On May 28, 2019, the Planning Commission of the Town of Danville recommended certification of the EIR to the Town Council and approval of the Project(Resolution No. ).Based upon the substantial evidence in the record, the Planning Commission finds and declares as stated herein. 3.3 The Town of Danville is the "lead agency" for the Project evaluated in the REIR. The Planning Commission finds that the REIR has been prepared in compliance with CEQA Statute and the State CEQA Guidelines. 3.4 The REIR evaluates all potentially significant impacts that can result from the Project. The REIR considered the significant and unavoidable environmental effects,if any,as well as cumulative impacts in each of these environ- mental topic areas in Chapter 4 and Appendix A of the Draft REIR. Additionally, the Draft REIR considered the following issues in Chapters 5 and 6: growth inducement, cumulative impacts, significant unavoidable im- pacts,irreversible environmental changes and alternatives. The cumulative impacts of the Project and other past, present, and reasonably foreseeable future projects were considered in the REIR as required by CEQA (Public Resources Code X21083) and the State CEQA Guidelines (Cal. Code of Regulations,Title 14, 515130). The cu- mulative analysis at the end of each section in Chapter 4 of the Draft REIR includes an analysis of future envi- ronmental conditions in the Town of Danville and surrounding areas to the extent required in order to determine the significance of the Project's incremental contribution to cumulative impacts. 3.5 The Planning Commission finds that the EIR provides objective information to assist the Town's decision- makers and the public-at-large in their consideration of the environmental consequences of the Project. The pub- lic review period provided all interested jurisdictions, agencies,private organizations, and individuals the oppor- I-5 1444592241 March 19, 2020 Regular Board Meeting Agenda Packet- Page 105 of 163 AMENDED AGENDA DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF Page 60 of 94 tunity to submit comments regarding the Draft EIR. The Final EIR was prepared after the public review period and responds to comments made during the public review period(August 31,2018 through October 15,2018),as well as those made at,or prior to the noticed public meetings and/or public hearings on the issues relevant to the REIR. 3.6 The-Planning Commission finds that the Town evaluated comments on environmental issues received from per- sons who reviewed the Draft REIR.In accordance with CEQA,the,Town prepared written responses describing the disposition of significant environmental issues raised.The Final REIR provides adequate,good faith,and rea- soned responses to the comments received by the Town. The Town has reviewed the comments received and re- sponses thereto and has determined that neither the comments received nor the responses to such comments add significant new information regarding environmental impacts to the Draft REIR, consistent with Public Re- sources Code 521092.1 and CEQA Guidelines X15088.5. Specifically,changes resulting from comments made on the Draft REIR do not result in the following: 1. A significant new environmental impact that would result from the Project or recommended mitigation measure; 2. A substantial increase in the severity of an environmental impact that is not reduced to a level of less than significant by adopted mitigation measures; 3. A feasible Project alternative or mitigation measure not adopted that is considerably different from oth- ers analyzed in the Draft REIR that would clearly lessen the significant environmental impacts of the Project;or 4. Information that indicates that the public was deprived of a meaningful opportunity to review and comment on the Draft REIR. The Planning Commission has based their recommendation on full appraisal of all viewpoints, including all comments received up to the date of adoption of these Findings, concerning the environmental impacts identi- fied and analyzed in the REIR. 3.6 These Findings are based upon substantial evidence in the entire record before the Town as described in Sec- tion 2.4. 3.7 The references to the Draft REIR and Final REIR set forth in these findings are for ease of reference and are not intended to provide an exhaustive list of the evidence relied upon for these findings. 3.8 These Findings reflect the Planning Commission's recommendations regarding the significance of impacts of the Project. 3.9 The Planning Commission certifies that it has independently reviewed and considered the information in the REIR. 3.10 CEQA defines the term"project" as the whole of an action or"activity which is being approved and which may be subject to several discretionary approvals by governmental agencies." Accordingly, the Planning Commission is recommending certification of the REIR and approval of these Findings for the entirety of the actions de- scribed in these Findings and in the REIR as comprising the Project. It is contemplated that there may be a variety of discretionary actions undertaken by other federal, state and local agencies (who might be referred to as "responsible agencies" under CEQA), concerning the Project, including without limitation: I-6 144459224.1 March 19, 2020 Regular Board Meeting Agenda Packet- Page 106 of 163 AMENDED AGENDA DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF Page 61 of 94 ♦ California Department of Fish and Wildlife(CDFG) ♦ California Regional Water Quality Control Board(RWQCB) ♦ San Francisco Bay Regional Water Quality Control Board(SFBRWQCB) ♦ U.S.Army. Corps of Engineers (ACOE) ♦ U.S.Fish and Wildlife Service(USFWS) Other agencies, organizations, and/or special interest groups not formally identified as a responsible agency,but otherwise anticipated to be participants in the local review process for the Project include: ♦ East Bay Municipal Utilities District(EBMUD) ♦ Contra Costa County Flood Control and Water Conservation District(CCCFWCD) ♦ Contra Costa Local Agency Formation Commission(LAFCo) ♦ East Bay Regional Parks District(EBRPD) ♦ Contra Costa County Because the Town of Danville is the lead agency for the Project, the EIR which the Town has prepared is intend- ed to be the basis for compliance with CEQA for each of the possible discretionary actions by other agencies to carry out the Project. 3.11 In several comments on the Draft REIR,various measures were suggested by commenters as proposed additional mitigation measures. Most of the proposed mitigation measures were for impacts that were less than significant. Based on the explanation and analysis in the REIR,these requests for additional mitigation measures are declined. 3.12 Having received,reviewed,and considered the above described information, as well as all other information and documents in the record,the Planning Commission hereby finds as stated in these Findings. 3.13 Pursuant to Public Resources Code X21081.6 and California Code of Regulations,Title 14, 515091,the Town of Danville is the custodian of the documents and other material that constitute the record of proceedings upon which the Town's decision is based,and such documents and other material are located at:Town of Danville De- velopment Services Department,510 La Gonda Way,Danville,California,94526. 4.0 FINDINGS REGARDING POTENTIALLY SIGNIFICANT IMPACTS AND MITIGATION MEASURES The REIR identified potentially significant impacts in the areas identified below. The REIR recommended mitigation measures to reduce all potentially significant impacts to a level of insignificance. All of these mitigation measures were also identified in the 2013 EIR; some have been modified to reflect Project changes (e.g., 381 rather than 372 acres of permanent open space) or feedback from agencies (e.g., EBMUD). Several mitigation measures identified in the 2013 EIR are not included in the REIR either because they have been incorporated into the Project Description or because they are no longer applicable to the Project as revised. 4.1 Aesthetics Impact: The project would create new sources of light that would adversely affect nighttime views in the area. Mitigation Measure 4.1-1 All buildings shall be designed so that reflective surfaces are limited and exterior light- ing is down-lit and illuminates the intended area only. Building applications for new structures shall include an exterior lighting plan subject to approval by the Town of Danville that includes the following requirements: 1) exterior lighting shall be direc- I-7 144459224.1 March 19, 2020 Regular Board Meeting Agenda Packet- Page 107 of 163 AMENDED AGENDA DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF Page 62 of 94 i tional; 2) the source of directional lighting shall not be directly visible; and 3) vegeta- tive screening shall be installed,where appropriate. Finding: The Planning Commission recommends the adoption of Mitigation Measure 4.1-1. Based on the explanation and analysis in the REIR,the Planning Commission finds that with the adoption of the Measure,the impact on aesthet- ics as described above will be mitigated to a less than significant level. 4.2 Biological Resources Impact: Construction of the proposed subdivision could result in potential impacts to California red-legged frog. Mitigation Measure 4.4-1 The project proponent shall implement the following measures during construction activities in or along East Branch Green Valley Creek to avoid take of individual CRLF: a. Prior to the start of construction, the project proponent shall retain a qualified biologist to train all construction personnel regarding habitat sensitivity, identification of special status species, and re- quired practices. b. Prior to the start of construction, the project proponent shall retain a qualified biologist to conduct pre-construction surveys to ensure that CRLF are absent from the construction area. If CRLF are pre- sent,a qualified biologist possessing all necessary permits shall relo- cate them or they shall be allowed to move out of the construction area on their own. C. Immediately following the pre-construction surveys and a determi- nation that CRLF are not present in the construction zone,the con- struction zone shall be cleared and silt fencing erected and main- tained around construction zones to prevent CRLF from moving into these areas. d. The project proponent shall retain a qualified biological monitor to be present onsite during times of construction within the riparian habitat of East Branch Green Valley Creek to ensure no CRLF are harmed,injured,or killed during project buildout. Mitigation Measure 4.4-2 The project would impact approximately 0.3 acres of moderate-quality riparian habitat resulting from construction of the vehicular bridges across East Branch Green Valley Creek. The project shall replace the lost value of this impact by restoring the impacted riparian habitat at a minimum 1:1 replacement-to-loss ratio. (Final mitigation amounts will be based on actual impacts to be determined during the design phase.) This shall be accomplished by restoring riparian habitat at the four following locations: a. The existing wet crossing and asphalt near the panhandle (i.e., where the new bridge-is to be constructed) shall be removed. The silt and sediment buildup behind and adjacent to the wet crossing and asphalt shall also be removed and the creek bed shall be low- 1-8 144459224.1 March 19, 2020 Regular Board Meeting Agenda Packet- Page 108 of 163 AMENDED AGENDA DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF Page 63 of 94 ered to restore the natural flow of this portion of the creek. b. The existing crossing from San Andreas Drive shall be removed and the creek restored in this area. C. The two existing cattle grates on Magee West near the existing cul- verts shall be removed. One of these is causing sediment build up and adversely impacting the creek. The natural flow of this channel shall be restored back to its original condition prior to the original installation of the grates. d. The riparian corridor along the East Branch of Green Valley Creek will be enhanced with suitable planting and placement of riparian vegetation along the proposed trail on Magee East. Approximately 2 acres along East Branch Green Valley Creek between the creek' and the trail is available to accommodate the minimum 0.3 acres of riparian enhancement plantings. The enhancement area shall be planted with native species appropriate for the corridor. Mitigation Measure 4.4-3 The project would impact approximately 0.5 acres of jurisdictional waters that are of a degraded quality and marginal value for the CRLF. The project shall replace the lost functions and value of this impact to aquatic habitats at a minimum of 1:1 replace- ment-to-loss acreage ratio. The final mitigation amounts will be based on actual im- pacts to be determined during the design phase. Habitat replacement via creation of and/or enhancements to existing waters shall occur onsite. Onsite lands proposed to be preserved as open space are within the same watershed as the offsite detention ba- sin known to support breeding CRLF and are expected to fully accommodate creation of and/or enhancements to aquatic habitats that would be of substantially higher value to CRLF than the impacted waters. Compensation for impacts to jurisdictional waters to benefit the CRLF will include all of the aforementioned components along with improving the wetland character of the onsite stock pond and enhancing the associat- ed riparian habitat between the stock pond and the detention basin. (Refer also to mitigation measures 4.4-13 and 4.4-14 below for impacts to jurisdictional waters.) Mitigation Measure 4.4-4 The project proposes to preserve approximately 381 acres of the site as open space. Areas to be preserved would be placed under a conservation easement or deed re- striction to prohibit construction and preserve conservation value. The project pro- poses to create a geologic hazard abatement district(GHAD) to provide suitable fund- ing for management and long-term maintenance of the site. Upland habitats shall be managed via a long-term management plan to maintain the quality of the habitat for the movement and dispersal of CRLF. Prior to construction, the project proponent shall retain a qualified biologist to prepare an open space management plan for the explicit purpose of managing and monitoring the proposed open space area.This plan shall be submitted to the Town of Danville for review and approval prior to issuance of grading permits. At a minimum this plan shall include the following components: a. Identify the location of the restoration efforts for replacing jurisdictional waters and riparian habitats. The replacement ratio for both habitats will be at a minimum of a 1:1 ratio. b. Identify the approaches to be used,including the extent that the onsite stock pond be expanded,reconfiguring of the pond bottom and increase in depth, and providing evidence that sufficient water budget exist for any proposed enhancement.

Identify a suitable planting regime for restoring wetland and riparian habitats. d. Identify success•criteria for monitoring both the wetland and riparian habitats that are consistent with similar habitats regionally. e. Monitor restored wetland habitats for at least five years and restored ri- parian habitats for 10 years. f. Define and identify the GHAD maintenance and management activities to manage the open space habitats to meet the stated goals of support habitat characteristics suitable for the CRLF. This would include suita- ble fencing so as to control access,limited cattle grazing or other proce- dures to manage grass height and forage production at levels that benefit the CRLF,and removal of trash. g. Define the financial mechanism for the GHAD to manage the open space into perpetuity. Finding: The Planning Commission recommends the adoption of Mitigation Measures 4.4-1 through 4.4-4. Based on the explanation and analysis in the REIR, the Planning Commission finds that with the adoption of these Measures,the impacts on biological resources as described above will be mitigated to a less than significant level. Impact: Construction of the proposed subdivision could result in potential impacts to western pond turtle. Mitigation Measure 4.4-5 Implementation of the avoidance, minimization, and compensation measures for the CRLF (see discussion above) would address impacts to western pond turtles. The project proponent shall also implement the following measures. Prior to the start of construction, the project proponent shall retain a qualified biolo- gist to train construction personnel regarding habitat sensitivity, identification of spe- cial status species,and required practices. Mitigation Measure 4.4-6 Prior to the start of construction within the East Branch Green Valley Creek riparian area, the project proponent shall retain a qualified biologist to conduct pre- construction surveys to ensure that western pond turtles are absent from the construc- tion area. If western pond turtles are present,a qualified biologist possessing allneces- sary permits shall be retained to relocate them. Mitigation Measure 4.4-7 If western pond turtles are found to be absent from the construction zone,immediate- ly following the pre-construction surveys the project proponent shall clear the con- struction zone and install/maintain silt fencing around the construction zone to pre- vent western pond turtles from entering these areas. Mitigation Measure 4.4-8 During construction within the East Branch Green Valley Creek riparian area, the project proponent shall retain a biological monitor to be present onsite during times of construction to ensure that turtles are not harmed,injured,or killed. Finding: The Planning Commission recommends the adoption of Mitigation Measures 4.4-5 through 4.4-8. Based on the explanation and analysis in the REIR,the Planning Commission finds that with the adoption of these Measures, the impacts on biological resources as described above will be mitigated to a less than significant level.

Mitigation Measure 4.4-9 To the maximum extent practicable, the project proponent shall remove trees during the non-breeding season (September 1 through January 31). If it is not possible to avoid tree removal and associated disturbances during the breeding season(February 1 through August 31),the project proponent shall retain a qualified biologist to conduct a pre-construction survey for tree-nesting raptors and other tree- or ground-nesting migratory birds in all trees or other areas of potential nesting habitat within the con- struction footprint and 250 feet of the footprint,if such disturbance would occur dur- ing the breeding season. This survey shall be conducted no more than 14 days prior to the initiation of demolition/construction activities during the early part of the breeding season (February through April) and no more than 30 days prior to the initiation of these activities during the late part of the breeding season (May through August). If nesting raptors or migratory birds are detected on the site during the survey,a suitable construction-free buffer shall be established around all active nests. The precise di- mension of the buffer (a minimum of 150 feet up to a maximum of 250 feet) shall be determined at that time and may vary depending on location and species. Buffers shall remain in place for the duration of the breeding season or until it has been confirmed by a qualified biologist that all chicks have fledged and are independent of their par- ents. Pre-construction surveys during the non-breeding season are not necessary, as the birds are expected to abandon their roosts during construction activities. Finding: The Planning Commission recommends the adoption of Mitigation Measure 4.4-9. Based on the explanation and analysis in the REIR,the Planning Commission finds that with the adoption of the Measure,the impacts on biologi- cal resources as described above will be mitigated to a less than significant level. Impact: Construction of the proposed subdivision could result in potential impacts to burrowing owls. Mitigation Measure 4.4-10 In order to avoid impacts to active burrowing owl nests, the project proponent shall retain a qualified biologist to conduct pre-construction surveys for burrowing owls within the construction footprint and within 250 feet of the footprint no more than 30 days prior to the onset of ground disturbance. These surveys shall be conducted in a manner consistent with the CDFG's burrowing owl survey methods (CDFG 2012b). If pre-construction surveys determine that burrowing owls occupy the site during the non-breeding season (September 1 through January 31), then a passive relocation ef- fort (e.g.,blocking burrows with one-way doors and leaving them in place for a mini- mum of three days) may be used to ensure that the owls are not harmed or injured during construction. Once it has been determined that owls have vacated the site,the burrows can be collapsed,and ground disturbance can proceed. If burrowing owls are detected within the construction footprint or immediately adjacent lands (i.e., within 250 feet of the footprint) during the breeding season (February 1 through August 31), a construction-free buffer of 250 feet shall be established around all active owl nests. The buffer area should be enclosed with temporary fencing, and construction equip- ment and workers may not enter the enclosed setback areas. Buffers must remain in place for the duration of the breeding season or until it has been confirmed by a quali- fied biologist that all chicks have fledged and are independent of their parents. After the breeding season, passive relocation of any remaining owls may take place as de- I-11 144459224.1 March 19, 2020 Regular Board Meeting Agenda Packet- Page 111 of 163 AMENDED AGENDA DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF Page 66 of 94 scribed above. Finding: The Planning Commission recommends the adoption of Mitigation Measure 4.4-10. Based on the explana- tion and analysis in the REIR, the Planning Commission finds that with the adoption of the Measure, the impacts on biological resources as described above will be mitigated to a less than significant level. Impact: Construction of the proposed subdivision could result in potential impacts to American badgers. Mitigation Measure 4.4-11 Pre-construction surveys conducted for burrowing owls shall also be used to deter- mine the presence or absence of badgers in the development footprint. If an active badger den is identified during pre-construction surveys within or immediately adja- cent to the construction envelope,the project contractor shall establish a construction- free buffer around the den of up to 300 feet or a distance specified by the resource agencies (i.e.,CDFG). Because badgers are known to use multiple burrows in a breed- ing burrow complex, the project contractor shall retain a biological monitor during construction activities to ensure the buffer is adequate to avoid direct impacts to indi- viduals or nest abandonment. The monitor shall be present onsite until it is deter- mined that young are of an independent age and construction activities would not harm individual badgers. Once it has been determined that badgers have vacated the site,the burrows can be collapsed or excavated,and ground disturbance can proceed. Finding: The Planning Commission recommends the adoption of Mitigation Measure 4.4-11. Based on the explana- tion and analysis in the REIR, the Planning Commission finds that with the adoption of the Measure, the impacts on biological resources as described above will be mitigated to a less than significant level. Impact: Development of the proposed subdivision would impact wetlands (0.5 acres) and riparian habitat(0.3 acres). Mitigation Measure 4.4-12 The project proponent shall replace wetland and riparian habitat at a 1:1 replacement- to-loss ratio. It is expected that all compensation measures can be accommodated within the 381 acres of the site proposed as open space. Prior to issuance of a grading permit, the project,proponent shall retain a qualified biologist to prepare an onsite habitat mitigation and monitoring plan (HMMP) that includes both an aquatic habitat restoration plan and a riparian habitat restoration plan. The HMMP would specifically address the wetland and riparian habitats and is separate from the Open Space Man- agement Plan identified in Mitigation 4.4-4, although there may be some overlap. The HMMP shall include the following components,at a minimum: a. Define the location of all restoration/creation activities; b. Provide evidence of a suitable water budget to support any created wet- land and riparian habitats; C. Identify the species,amount,and location of plants to be installed; d. Identify the time of year for planting and method for supplemental wa- tering during the establishment period; C. Identify the monitoring period,which should be not less than 5 years for wetland restoration and not less than 10 years for riparian restoration, defines success criteria that will be required for the wetland restoration to be deemed a success; f. Identify adaptive management procedures that include (but are not lim- I-12 144459224.1 March 19, 2020 Regular Board Meeting Agenda Packet- Page 112 of 163 AMENDED AGENDA DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF Page 67 of 94 ited to) measures to address colonization by invasive species,unexpected lack of water, excessive foraging of installed wetland plants by native wildlife,and similar; g. Define management and maintenance activities (weeding of invasives, providing for supplemental water, repair of water delivery systems) of the proposed GRAD;and h. Provide for assurance in funding the monitoring and ensuring that the created wetland and riparian habitats fall within lands to be preserved and managed into perpetuity. Confirm that the proposed GHAD will meet these responsibilities. Mitigation Measure 4.4-13 The project proponent shall comply with all state and federal regulations related to construction work that will impact aquatic habitats occurring on the site. Prior to con- struction, the project proponent shall obtain a Section 404 Clean Water Act permit from the USACE,Section 401 Water Quality Certification from the RWQCB,and/or Section 1600 Streambed Alteration Agreement from the CDFG, and submit proof of such documentation to the Town of Danville. Finding: The Planning Commission recommends the adoption of Mitigation Measures 4.4-12 through 4.4-13. Based on the explanation and analysis in the REIR, the Planning Commission finds that with the adoption of these Measures, the impacts on biological resources as described above,will be mitigated to a less than significant level. Impact: The project would result in the removal of 49 trees on the site,which represents a potentially significant impact. Mitigation Measure 4.4-14 Prior to issuance of a grading permit,a tree preservation plan shall be prepared for all trees to be retained that identifies all protection and mitigation measures to be taken and includes the tree preservation guidelines by HortScience in their tree report(s). These measures shall remain in place for the duration of construction activities at the project site. Mitigation Measure 4.4-15 Upon completion of construction, the project proponent shall replace all ordinance- size trees to be removed with approved species"of a cumulative number and diameter necessary to equal the diameter of the tree(s) which are approved for removal"in ac- cordance with the Town's tree ordinance. Tree removal shall be conducted in accord- ance with the Town's requirements, including planting a mixture of small and large box trees to meet the cumulative diameter number of the removed trees. The project proponent shall replace all non-ordinance-size trees (i.e., trees less than 10 inches in diameter for single-trunk trees or less than 20 inches in diameter for multi-trunk trees) at a replacement-to-removal ratio of 1:1.To the maximum extent practicable,all native trees that are removed shall be replaced with like species. All non-native trees that are removed shall be replaced with species that are known to occur naturally within similar habitats in the region. Mitigation Measure 4.4-16 Prior to construction,the project proponent shall retain a qualified arborist to develop a monitoring plan for replacement trees (outside the riparian habitat) and submit it to the Town of Danville during the permit process. The basic components of the moni- toring plan shall include final success criteria,specific performance criteria,monitoring methods, data analysis, monitoring schedule, contingency/remedial measures, and I-13 144459224.1 March 19, 2020 Regular Board Meeting Agenda Packet- Page 113 of 163 AMENDED AGENDA DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF Page 68 of 94 reporting requirements. Finding: The Planning Commission recommends the adoption of Mitigation Measures 4.4-14 through 4.4-16. Based on the explanation and analysis in the REIR, the Planning Commission finds that with the adoption of these Measures, the impacts on biological resources as described above will be mitigated to a less than significant level. Impact: The improvements to the Diablo Road/Green Valley Road intersection would require the removal of 18 trees within the Town right-of-way,which represents a significant impact. Mitigation Measure 4.4-17 The Project shall implement Mitigation Measures 4.4-14 through 4.4-16 as applicable. Finding: The Planning Commission recommends the adoption of Mitigation Measure 4.4-17. Based on the explana- tion and analysis in the REIR, the Planning Commission finds that with the adoption of the Measure, the impacts on biological resources as described above will be mitigated to a less than significant level. 4.3 Cultural Resources Impact: Construction of the project may result in the discovery and disturbance of un- known archaeological resources and/or human remains. Mitigation Measure 4.5-1 If during the course of project construction, archaeological resources or human re- mains are accidentally discovered during construction,work shall be halted within 20 feet of the find until a qualified professional archaeologist can evaluate it. Work shall not recommence until the project archaeologist has submitted documentation to the Town indicating that discovered resources have been adequately salvaged and no fur- ther resources have been identified within the area of disturbance. Mitigation Measure 4.5-2 Pursuant to Section 7050.5 of the Health and Safety Code and Section 5097.94 of the 'Public Resources Code of the State of California,in the event of the discovery of hu- man remains during construction, no further excavation or disturbance shall be con- ducted on the site or any nearby area reasonably suspected to overlie adjacent remains. The Contra Costa County Coroner shall be notified and make a determination as to whether the remains are Native American. If the Coroner determines that the remains are not subject to his authority,he shall notify the Native American Heritage Commis- sion who shall attempt to identify descendants of the deceased Native American. If no satisfactory agreement can be reached as to the disposition of the remains pursuant to this State law,then the land owner shall re-inter the human remains and items asso- ciated with Native American burials on the property in a location not subject to fur- ther subsurface disturbance. Finding: The Planning Commission recommends the adoption of Mitigation Measures 4.5-1 through 4.5-2. Based on the explanation and analysis in the REIR,the Planning Commission finds that with the adoption of these Measures, the impacts on cultural resources as described above will be mitigated to a less than significant level. Impact: Construction of the project may result in the discovery and disturbance of un- known paleontological resources. Mitigation Measure 4.5-3 If during the course of project construction,paleontological resources are accidentally I-14 144459224.1 March 19, 2020 Regular Board Meeting Agenda Packet- Page 114 of 163 AMENDED AGENDA DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF Page 69 of 94 discovered during construction,work shall be halted within 20 feet of the find until a qualified professional paleontologist can evaluate it. Work shall not recommence until the project paleontologist has submitted documentation to the Town indicating that discovered resources have been adequately salvaged and no further resources have been identified within the area of disturbance. Finding: The Planning Commission recommends the adoption of Mitigation Measure 4.5-3. Based on-the explanation and analysis in the REIR,the Planning Commission finds that with the adoption of the Measure,the impacts on paleon- tological resources as described above will be mitigated to a less than significant level. 4.4 Geotechnical Impact 4.6-1 Construction of the project could result in temporary soil erosion and loss of topsoil Mitigation Measure 4.6-1 In order to reduce wind and water erosion on the project site, an erosion control plan and Storm Water Pollution Prevention Plan (SWPPP) shall be prepared for the site preparation,construction,and post-construction periods (see mitigation measure 4.8-1 in 4.8 Hydrology and Water Quality). The project shall prepare an erosion control plan in accordance with the Town's Ero- sion Control Ordinance. The project proponent shall implement the. following measures, where appropriate, to control erosion: 1) keep construction machinery off of established vegetation as much as possible, especially the vegetation on the upwind side of the construction site;2) establish specific access routes at the planning phase of the project, and limits of grading prior to development, which should be strictly ob- served; 3) utilize mechanical measures (i.e.,walls from sand bags and/or wooden slat or fabric fences)to reduce sand movement;4)immediate re-vegetation(plus the use of temporary stabilizing sprays),to keep sand movement to a minimum;and 5)for larger- scale construction,fabric or wooden slat fences should be placed around the construc- tion location to reduce sand movement. This erosion control plan shall be submitted to the Town of Danville for review and approval prior to issuance of a grading permit. Finding: The Planning Commission recommends the adoption of Mitigation Measure 4.6-1. Based on the explanation and analysis in the REIR, the Planning Commission finds that with the adoption of the Measure, the impacts on ge- otechnical as described above will be mitigated to a less than significant level. 4.5 Hazards&Hazardous Materials Impact: Development of the proposed project,including excavation and other land dis- turbance, could result in the release of hazardous materials that may be present on portions of the project site, exposing construction personnel and the envi- ronment to potential health and safety risks. Mitigation Measure 4.7-1 In order to minimize potential human health hazards associated with the historical use of hazardous materials on portions of the project site, the project proponent shall re- tain a trained professional to prepare a Site Management Plan to maintain the safety of construction workers and assure proper management of any contaminated soils on the site in accordance with federal, state and local regulatory requirements. This plan shall I-15 144459224.1 March 19, 2020 Regular Board Meeting Agenda Packet- Page 115 of 163 AMENDED AGENDA DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF Page 70 of 94 be subject to review and approval by Contra Costa County Health Services, and evi- dence of approval provided to the Town of Danville,prior to the issuance of any grad- ing permit, demonstrating that all necessary remedial actions have been completed pursuant to the approved Site Management Plan. At a minimum, the Site Manage- ment Plan shall include 1) the collection and chemical analysis of soil samples from the former UST location and 2) excavation and soils characterization to confirm that suf- ficient soils removal has occurred for OCPs and elevated 4, 4-DDE at location SB-3, and 3) proper removal and disposal of all hazardous materials on the site, including contaminated soils, chemical containers observed in the storage shed, and herbicides spray bottles at an approved disposal facility. Finding: The Planning Commission recommends the adoption of Mitigation Measure 4.7-1. Based on the explanation and analysis in the REIR,the Planning Commission finds that with the adoption of the Measure,the impacts on hazards and hazardous materials as described above will be mitigated to a less than significant level. 4.6 Hydrology&Water Quality Impact: Construction and operation of the project could impact surface water quality. Mitigation Measure 4.8-1 In order to avoid water quality impacts, a Storm Water Pollution Prevention Plan (SWPPP) shall be prepared for the site preparation, construction, and post- construction periods. The SWPPP shall incorporate best management practices con- sistent with the requirements of the National Pollution Discharge Elimination System (NPDES) Municipal Stormwater permit (No. CAS612008). The project proponent shall obtain a NPDES General Construction Permit and prepare the SWPPP in ac- cordance with all legal requirements,prior to the issuance of a grading permit. Addi- tional requirements for erosion control are detailed in mitigation measure 4.6-1 in 4.6 Geotechnical and Geologic Hazards. Finding: The Planning Commission recommends the adoption of Mitigation Measure 4.8-1. Based on the explanation and analysis in the REIR,the Planning Commission finds that with the adoption of the Measure,the impacts on hydrol- ogy and water quality as described above will be mitigated to a less than significant level. 4.7 Public Services Impact: The project would result in an incremental increase in the student population in the SRVUSD. Mitigation Measure 4.11-1 The applicant shall pay a school impact fee pursuant to the criteria set forth within California Government Code Section 65995.Prior to the issuance of building permits, the applicant shall pay required school mitigation fees, subject to the review and ap- proval of the Town of Danville and San Ramon Valley Unified School District. The fees set forth in Government Code Section 65996 constitute the exclusive means of both"considering" and"mitigating" school facilities impacts of projects [Government Code Section 65996(a)]. They are"deemed to provide full and complete school facili- ties mitigation" [Government Code Section 65996(b)].

Based on the explana- tion and analysis in the REIR, the Planning Commission finds that with the adoption of the Measure, the impacts on public services as described above will be mitigated to a less than significant level. 4.8 Transportation&Circulation Impact: The project trips added to the intersection of Diablo Road/Blackhawk Road& Mt. Diablo Scenic Boulevard under Existing plus Project and Cumulative plus Project Conditions will increase the V/C ratio by more than 5 percent during the AM and School PM peak hours, which constitutes a significant impact based on the established thresholds of significance. Mitigation Measure 4.3-1 Install a traffic signal at the intersection of Diablo Road/Blackhawk Road&Mt. Dia- blo Scenic Boulevard at the applicant's expense. With signalization, the intersection would operate at LOS A or B under all scenarios. Finding: The Planning Commission recommends the adoption of Mitigation Measure 4.12-1. Based on the explana- tion and analysis in the REIR, the Planning Commission finds that with the adoption of the Measure, the impacts on traffic and circulation as described above will be mitigated to a less than significant level. The Planning Commission further finds that Mitigation Measure 4.3-1 is within the responsibility and jurisdiction of Contra Costa County and not the Town, and that the County can and should adopt this Measure. If the County does not adopt this Measure, this traffic congestion impact will be significant and unavoidable. The Planning Commission addresses this potential significant and unavoidable impact in the Statement of Overriding Considerations in Section II. 4.9 Utilities Impact: Development of the proposed project would require the construction of new water infrastructure in order to serve the project. EBMUD has identified that specific improvements may be necessary to serve new uses. These improve- ments are necessary to mitigate potential water supply infrastructure impacts. Mitigation Measure 4.13-2 Prior to the recordation of the final map for each phase of development,the applicant shall submit detailed design-level infrastructure drawings approved by the East Bay Municipal Utility District to the Town of Danville for review and approval. All new water supply infrastructure shall be designed in accordance with all applicable East Bay Municipal Utility District specifications. All water supply infrastructure plans shall be reviewed and approved prior to final map recordation. Mitigation Measure 4.13-3 The East Bay Municipal Utility District maintains a right-of-way (R/W 1581) through the project site,which provides access to the Green Valley Reservoir.In order to avoid potential effects to East Bay Municipal Utility District's existing operations, the final map shall clearly delineate all known easements, including East Bay Municipal Utility I-17 144459224.1 March 19, 2020 Regular Board Meeting Agenda Packet- Page 117 of 163 AMENDED AGENDA DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF Page 72 of 94 District's right-of-way(R/W 1581).Any and all activities proposed within the right-of- way shall be coordinated with East Bay Municipal Utility District.This easement shall be reflected in all final design-level improvement plans and appropriate notes shall also be included, subject to the review and approval of the East Bay Municipal Utility Dis- trict and the Town of Danville. Finding: The Planning Commission recommends the adoption of Mitigation Measures 4.13-2 and 4.13-3. Based on the explanation and analysis in the REIR,the Planning Commission finds that with the adoption of these Measures,the impacts on utilities as described above will be mitigated to a less than significant level. 5.0 FINDINGS RELATED TO CUMULATIVE IMPACTS AND MITIGATION MEASURES CEQA Guidelines require consideration of the potential cumulative impacts that could result from a proposed project in conjunction with other projects in the vicinity. Such impacts can occur when two or more individual effects create a considerable environmental impact or compound other environmental consequences. An explanation of the cumulative impact analysis is in Section 5.2 of the Draft REIR. One significant cumulative impact was found for the Project,in the area of traffic congestion. This cumulative impact can be mitigated to a level of insignificance as discussed above. If the County declines to adopt Mitigation Measure 4.3- 1 (signalization of the Diablo Road/Blackhawk Road&Mt. Diablo Scenic Boulevard intersection) then this impact will be significant and unavoidable. There is no evidence in the record to indicate the County will not adopt the Measure. However,a Statement of Overriding Considerations is included in Section II in response to that unlikely scenario. 6.0 FINDINGS REGARDING MONITORING OF MITIGATION MEASURES In order to ensure that the mitigation measures identified herein are implemented, the Planning Commission recom- mends the adoption of the Mitigation Monitoring and Reporting Program include with the Project approvals. 7.0 FINDINGS REGARDING ALTERNATIVES CEQA Guidelines§15126.6 requires a discussion of a reasonable range of alternatives to the project or to the location of the project. However,an EIR need not consider an alternative whose implementation is remote or speculative. An EIR is required to describe and comparatively evaluate a range of reasonable alternatives to a project, or location of the pro- ject, that would feasibly attain most of the basic objectives of the project but would avoid or substantially lessen any of the significant effects of the project. Thus,the range of alternatives evaluated in the Draft REIR was dictated by CEQA and by the range of significant impacts identified in the Draft REIR,and evaluated alternatives were limited to those that theoretically could have reduced or eliminated identified environmental impacts. The Draft REIR also considered and rejected two alternatives from further consideration. First,an alternative location was not carried forward for analysis since there is no other site that can accommodate the Project and implement the criteria specified in the General Plan that identify the Project site as an Area of Special Concern. Second,Alternative 5 from the 2013 EIR (a 66-unit, 20,000-sf-lot alternative) was not carried forward for analysis because the proposed Pro- ject no longer includes custom lots;20,000-square-foot lots would increase footprint impacts compared to the Proposed Project; and the number of residential lots in this alternative (66) was virtually the same as the 69 lots in the proposed Project and in Alternative 3. The Draft REIR discussed the following alternatives in detail: 1. No Project/No Build 1-18 144459224.1 March 19, 2020 Regular Board Meeting Agenda Packet- Page 118 of 163 AMENDED AGENDA DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF Page 73 of 94 2. No Project/Build without Subdivision(7 residential lots) 3. More Clustered Alternative/Minimum 5,000 SF Lots(69 residential lots) 4. Non-Clustered Alternative(78 residential lots,no zone change) Each of these alternatives was evaluated under the same environmental categories as presented for the Project and as identified in Chapter 4 and Appendix A of the Draft REIR. Based on the comparison of the relative merits of each al- ternative compared to the Project, each of the alternatives was found to be deficient in meeting the Project's goals and objectives,and Alternative 4 would cause greater environmental impacts. The Final REIR at pages 27-28, explains why alternatives suggested by commenters would not meet project objectives, would not reduce environmental impacts, or both. These alternatives are: a) a reduction in residential lots sufficient to avoid the Project's significant traffic congestion impact at Diablo Road/Blackhawk Road & Mt. Diablo Scenic Boule- vard (which would not require the applicant to signalize the intersection and therefore would maintain the intersection's current LOS E and F at AM peak and School PM Peak hours, respectively); b) nine 20-acre parcels on land currently zoned Agricultural,with small clusters elsewhere on the site (which would spread development more widely across the site,adding to visual impacts and failing to meet the project objective of extensive public open space);and c) elimination of the three residential lots at Magee West (which would not avoid any significant traffic impact).The overall objectives of the Project are to: ♦ Develop a residential project that is consistent with the Town of Danville Agricultural, General Open Space,Rural Residential, and Single Family-Low Density General Plan Land use designations for the site as well as the General Plan's Magee Ranch Special Concern Area language, ♦ Provide 69 residential lots,including 66 home sites at the east end of site south of Blackhawk Road, and 3 homes sites near the southeast corner of the Diablo Road/McCauley road intersection, ♦ Design the project to cluster development on the lower portions of the site to minimize visual impacts and limit dis- turbance on the property, ♦ Provide for a minimum of 10% of the 69 lots to include a second dwelling unit ("casita") to satisfy the Town's af- fordable housing requirements, ♦ Preserve approximately 381 acres of the project site as permanent open space,and ♦ Preserve significant features of scenic hillsides and major ridgeline areas. 7.1 No Project/No Build Alternative 7.1.1 Description of Alternative 1 CEQA requires the discussion of the No Project Alternative "to allow decision makers to compare the impacts of approving the proposed project with the impacts of not approving the proposed project." For the purposes of this analysis the No Project Alternative represents the "no development" scenario in which the site is left in its current generally undeveloped condition (per CEQA Guidelines Section 15126.6(e)(3)) and existing ranching uses continuing to operate. This alternative would eliminate the preservation of over 381 acres of the site in permanent open space,with public trails,proposed by the Project. 7.1.2 Rejection of Alternative The No Project Alternative would avoid all of the environmental impacts of the proposed Project. The No Project Alternative would result in the continuation of the existing operation of ranching uses on the site (which would also be continued on most of the Project site under the proposed Project). The No Project Alternative is infeasible because it I-19 144459224.1 March 19, 2020 Regular Board Meeting Agenda Packet- Page 119 of 163 AMENDED AGENDA DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF Page 74 of 94 would fail to meet any project objectives, including to build•a residential community on the site consistent with the existing zoning and General Plan and preserve over 381 acres in permanent open space. The Alternative would not provide public access through a trail system. 7.2 Project/Build Without Subdivision 7.2.1 Description of Alternative The No Project/Build Alternative consists of eliminating the proposed subdivision and developing the project site with one residential lot per existing parcel. Since the site currently contains seven buildable parcels, this alternative would result in the construction of a total of seven residential homes.on the site.This alternative would require the provision of infrastructure to each individual parcel, including roads,water, power, and sanitary sewer. It is assumed that each lot would require its own water well and septic system, although it may be technically possible to connect these parcels to the public system via lengthy lateral extensions. This alternative would eliminate the preservation of over 381 acres of the site in permanent open space proposed by the Project. 7.2.2 Rejection of Alternative This alternative would lessen the environmental impacts of the Project by decreasing total unit count from 69 lots to 7 lots. This alternative is infeasible because it would fail to meet any project objectives, including to develop a 69-lot residential community on the site and preserve over 381 acres in permanent open space. 7.3 More Clustered Alternative/Minimum 5,000 S.F. Lots 7.3.1 Description of Alternative This alternative consists of the development of the site with 69 lots sized a minimum of 5,000 square feet, within a smaller development footprint than the proposed Project. This alternative would eliminate development on approxi- mately ten acres,primarily within the south portion of Magee East,by eliminating the southernmost portion of Court F. This area of development was eliminated to provide a logical boundary for the smaller footprint scenario,primarily from an engineering perspective. This alternative comprises three lots on Magee West and 66 lots on Magee East.This alter- native is intended to reduce overall site disturbance compared with the Project. 7.3.2 Rejection of Alternative The 5,000 SF lot alternative would lessen some impacts of the Project associated with site disturbance since the devel- opment footprint would be reduced. These areas include aesthetics, cultural resources,and geology/soils,which repre- sent potential significant but mitigable impacts for the proposed Project. For many areas,including traffic congestion, the impacts would be unchanged due to the number of residential units. This alternative is rejected as infeasible because it would create an abrupt change in density compared to existing residential neighborhoods adjoining the project site. 7.4 Non-Clustered Alternative 7.4.1 Description of Alternative This alternative consists of the development of the project site with 78 lots, with most lots sized a minimum of five acres. This alternative comprises 67 five-acre lots on the portions of the site covered by the Town's Residential—Rural Residential or Public and Open Space—Agricultural General Plan land use designations.The five-acre portion of the site covered with the Town's Residential—Single Family—Low Density General Plan land use designation(opposite Fairway Drive)would contain 11 lots with a minimum size of 13,000 square feet. This alternative would eliminate the preserva- tion of over 381 acres of the site in permanent open space proposed by the Project. I-20 144459224.1 March 19, 2020 Regular Board Meeting Agenda Packet- Page 120 of 163 AMENDED AGENDA DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF Page 75 of 94 This alternative would not cluster development on the flatter portions of the site but rather develop the majority of the project site with five-acre "ranchettes." This alternative consists of 24 lots on Magee West and 54 lots on Magee East. The lot configuration under this alternative would not allow for preservation of large-portions of the project site in open space. This alternative is being evaluated at the request of the community at the scoping meeting for the 2013 EIR, as well as because it is the type of development that could occur on the site using zoning that is consistent with the Town's 2010 General Plan land use designations for the project site other than the P-1; Planned Unit Development District. This alternative would not conform to the Town's General Plan policies that recommend development be concentrated on the flatter less visible portions of the site. 7.4.2 Rejection of Alternative This alternative is infeasible because it would increase environmental impacts compared to the proposed Project and would not meet project objectives. This alternative would introduce non-clustered development on the entire site. This would result in substantially greater, significant aesthetic impacts due to viewshed alteration. It would result in greater land disturbance impacts by requiring additional grading,an extensive roadway system,and additional project infrastruc- ture to provide service and access to each lot. The overall impacts of this alternative would be substantially greater than the Project. This alternative would not meet the Project objectives to cluster development on the flatter portions of the site and minimize grading and infrastructure requirements. Moreover,the Project,as approved,includes fewer housing units. This alternative would not conform to the policy of the Magee Ranch Special Concern Area identified in the General Plan,which"strongly discourages" subdivision of the property into 5-acre ranchettes and encourages clustering of development. 8.0 GROWTH INDUCING IMPACTS Finding: The Planning Commission finds that the Project will not result in significant growth inducing impacts be- cause the Project does not allow for development that creates population or other growth beyond what is currently per- mitted under the Town's 2010 General Plan and 2030 General Plan. The Project would not establish policies nor add infrastructure which would induce further growth in the vicinity.

The REIR identified mitigation measures that can reduce all potential environmental impacts to less than significant level. The Mitigation Measure to reduce the Project's contribution to traffic at the intersection of Mt. Diablo Scenic/Diablo (Measure 4.3-1),is within the responsibility and jurisdiction of Contra Costa County and not the Town. If the County does not adopt this Measure, this traffic impact will be significant and unavoidable. There is no evidence in the record from Contra Costa County will not implement this Measure. Rather, the letter from the County commenting on the Draft REIR(Comment Letter 1 in Final REIR)is supportive of the measure.. The Planning Commission has found,in Section I above,that the County can and should adopt Mitigation Measure 4.3- 1. Nevertheless,it is not certain at this stage that the County will adopt this measure. For this reason, a Statement of Overriding Considerations is presented. In accordance with Public Resources Code §21081(b) and CEQA Guidelines X15093, the Planning Commission has, in determining whether or not to recommended approval of the Project, bal- anced the economic, social, technological, environmental, and other benefits of the Project against this potential una- voidable environmental effect, and has found that the benefits of the Project outweigh this possibility, for the reasons set forth below. This Statement of Overriding Considerations is based on the Planning Commission's review of the REIR and other information in the administrative record. The Planning Commission finds that each of the following benefits is an overriding consideration,independent of the other benefits,that warrants approval of the Project notwith- standing the possibility of a significant unavoidable impact. 2.0 Overriding Considerations Substantial evidence is included in the record of these proceedings and in documents relating to the Project demonstrat- ing the benefits which the Town would derive from the implementation of the Project. The Planning Commission has balanced the economic and social benefit of the Project against the possible unavoidable environmental impact that can occur if the County fails to adopt Mitigation Measure 4.3-1,and concludes that the economic,social and environmental benefits that will be derived from the Project outweigh that potential environmental impact. Upon balancing the envi- ronmental risks and countervailing benefits, the Planning Commission concludes that the benefits derive from the Pro- ject outweigh that potential environmental risk. The specific benefits are as follows: • The Project is consistent with the goals and policies in the Town's General Plan, Zoning Ordinance and other planning documents and provides a density of 69 units which is below the allowable density range of 78 units. W The Project implements the direction in the General Plan relating to contemplated development in the Plan- ning Area/Special Concern Area for this property by clustering development to the least sensitive and obstruc- tive areas of the site. • The Project will provide 381 acres(out of 410 acres)in permanent open space. • The Project as conditioned will be required to make improvements to the intersection of Diablo Road/Green Valley Road even though the Project does not create significant traffic impacts at this intersection. These im- provements will improve traffic flow at the intersection. • The Project will provide 69 housing units to the area,in addition to 7 affordable units. These new units will in- crease the housing alternatives available to home buyers and generate economic activity in the area. 012267.0006\3082006.1 The Planning Center I DC&1; II-1 144459224.1 March 19, 2020 Regular Board Meeting Agenda Packet- Page 122 of 163 AMENDED AGENDA DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF Page 77 of 94 0 The General Plan establishes the goal of providing affordable housing opportunities. The Project will help meet these affordable housing needs by constructing seven casitas as affordable housing. • The Project will provide a pedestrian/bicycle trail adjacent to Diablo Road and hiking trails that will allow op- portunities to establish park and trail connections to Sycamore Valley Open Space. • The Project will provide an alternative access route to be used in emergencies along a segment of Diablo Road. The Planning Commission finds that the above described benefits which will be derived from the Project,when weighed against the absence of the Project,override the significant and unavoidable traffic congestion impact that may result. 3.0 Summary Based on the foregoing Findings and the information contained in the Record,the Planning Commission has made one or more of the following findings with respect to each of the significant environmental effects of the Project: 1) Changes or alterations have been required in,or incorporated into,the Project which mitigate or avoid the sig- nificant effects on the environment. 2) Those changes or alterations are within the responsibility and jurisdiction of another public agency and have been,or can and should be,adopted by that other agency. This Finding relates to Mitigation Measure 4.3-1. 3) Specific economic, legal, social, technological, or other considerations,including considerations for the provi- sion of employment opportunities for highly trained workers,make infeasible the mitigation measures or alter- natives identified in the environmental impact report. Based on the foregoing findings and the information contained in the record,it is determined that: 1) All significant effects on the environment due to the approval of the Project have been eliminated or substan- tially lessened where feasible. 2) Any remaining significant effects on the environment found to be unavoidable are acceptable due to the factors described in the Statement of Overriding Considerations and the Planning Commission recommends that the Project should be approved.
