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 Preparati on (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 DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF PAGE 3 OF RESOLUTION NO. 46-2019 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 DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF PAGE 4 OF RESOLUTION NO. 46-2019 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. The Town Council finds that the Final Revised EIR has been prepared in compliance with CEQA, and reflects the independent judgment and analysis of the Town of Danville. Section 2. The Town Council declares that it has made a reasonable and good faith effort to eliminate or substantially mitigate, through adoption of all fea sible mitigation measures, all potentially significant 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: DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF PAGE 5 OF RESOLUTION NO. 46-2019 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. DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF PAGE 6 OF RESOLUTION NO. 46-2019 3. The Town further finds that the rezoning for residential deve lopment 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 infrastruct ure 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 DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF PAGE 7 OF RESOLUTION NO. 46-2019 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, DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF PAGE 8 OF RESOLUTION NO. 46-2019 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. DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF PAGE 9 OF RESOLUTION NO. 46-2019 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. Necessity. 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 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 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. DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF PAGE 10 OF RESOLUTION NO. 46-2019 Removal of the 67 trees, including 15 Town-protected trees, would not significantly affect off-site shade or adversely affect privacy between properties due to the site’s topography, the other trees that would remain, and the locations of the trees in relation to other properties.

The applicant shall be required to secure an appraisal of the condition and value of all such potentially affected trees. The appraisal shall be done in accordance with the current edition of the “Guide for Establishing Values of Trees and Other Plants,” by the Council of Tree and Landscape Appraisers under the auspices of the International Society of Arboriculture. The appraisal shall be performed by a Certified Arborist, and shall be subject to review and approval by the Chief of Pl anning. A tree preservation agreement shall be prepared and shall be submitted for review and approval by the Planning Division that outlines the intended and allowed use of funds posted as a tree preservation security deposit. That portion of the security deposit still held by the Town two full growing seasons after project completion shall be returned upon verification that the trees covered by the deposit are as healthy as can be provided for under the terms of the approved tree preservation agreement. DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF PAGE 21 OF RESOLUTION NO. 46-2019 * 6. A minimum of two street trees per lot (three for corner lots) shall be incorporated into the final landscape and irrigation plan for the project. 7. The proposed open wire fencing shall include a rigid and durable top bar to prevent the fence from sagging. All applicant-installed fencing shall be subject to review and approval by the Planning Division and the Design Review Board as part of a Final Fencing Location, Design and Construction Details submittal. 8. The project’s homeowner’s association shall be responsible for the maintenance of all landscaping within the public right-of-way along Blackhawk Road at the main project entry. 9.

The development of Lots 1, 67, 68, and 69 of this subdivision shall be limited to single story homes only. E. BIOLOGICAL 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 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: DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF PAGE 23 OF RESOLUTION NO. 46-2019 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 DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF PAGE 24 OF RESOLUTION NO. 46-2019 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. DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF PAGE 25 OF RESOLUTION NO. 46-2019 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 con struction. 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 DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF PAGE 26 OF RESOLUTION NO. 46-2019 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 a n 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; DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF PAGE 27 OF RESOLUTION NO. 46-2019 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. DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF PAGE 28 OF RESOLUTION NO. 46-2019 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. The notice shall include a list of contact persons with name, title, phone number and area of responsibility. The person responsible for maintaining the list shall be included. The list shall be kept current at all times and shall consist of persons with authority to initiate corrective action in their area of responsibility. The names of individuals responsible for dust, noise and litter control shall be expressly identified in the notice. * 3. Development shall be completed in compliance with a detailed soils report and the construction grading plans prepared for this project. The engineering recommendations outlined in the project specific soils report shall be incorporated into the design of this project. The report shall include specific recommendations for foundation design of the proposed buildings and shall be subject to review and approval by the Town’s Engineering and Planning Divisions. * 4. Where soils or geologic conditions encountered in grading operations are different from that anticipated in the soil report, a revised soils report shall be submitted for review and approval by the City Engineer. It shall be accompanied by an engineering and geological opinion as to the safety of the site from settlement and seismic activity. DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF PAGE 29 OF RESOLUTION NO. 46-2019 5. 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 consistent 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 accordance with all legal requirements, prior to the issuance of a grading permit. Additional requirements for erosion control are detailed in mitigation measure 4.6-1 in 4.6 Geotechnical and Geologic Hazards. * 6. All new development shall be consistent with modern design for resistance to seismic forces. All new development shall be in accordance with the Uniform Building Code and Town of Danville Ordinances. * 7. All cut and fill areas shall be appropriately designed to minimize the effects of ground shaking and settlement. * 8. Stockpiles of debris, soil, sand or other materials that can be blown by the wind shall be covered. * 9. If toxic or contaminated soil is encountered during construction, all construction activity in that area shall cease until the appropriate action is determined and implemented. The concentrations, extent of the contamination and mitigation shall be determined by the Contra Costa County Health Department. Suitable disposal and/or treatment of any contaminated soil shall meet all federal, state and local regulations. If deemed appropriate by the Health Department, the applicant shall make provisions for immediate containment of the materials. 10. Runoff from any contaminated soil shall not be allowed to enter any drainage facility, inlet or creek. 11. In order to minimize potential impacts from landslides, final project design plans shall incorporate the recommendations in the preliminary geotechnical report, which includes the following corrective measures: a. Landslide avoidance; b. Construction of catchment areas between landslides and proposed improvements; c. Partial landslide debris removal and buttressing with engineered fill; and DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF PAGE 30 OF RESOLUTION NO. 46-2019 d.

Section 1.2 provides a description of the public review process that has led decision makers to their conclusions regarding the Magee Preserve Project (?roject). Section 2.0 presents the purpose and background of the ?roject, including a ptoiect description, to provide the context upon which these Findings ate based. Section 3.0 presents the substantiation for certiÊcation 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 potentiâlly significant impacts. Section 6.0 contains the Findrngs for cumulative impacts and Section 7.0 contains Findings regarding monitoring of mitigation meâsutes. Section 8.0 contains Findings tegarding the altematives to the Project. Secdon 9.0 contains Findings for gtowth-inducing impacts. The Statement of Overriding Considerations in contained in Section II. 1.1 Califomia Envitonmental Quality Act The California Environmental Quality Act ("CEQA") (Public Resources Code $21000-21177) and the State CEQÀ Guidelines (Cal. Code of Regulations, Title 14, 515000-15387) require that specific findings be made if a lead agency decides to approve a project which v¡ill have significant impacts. $21081 of the California Public Resources Code states: [N]o public agency shall approve ot ca:rry out a project for which ar.r Environmental Impact Report. has been cer- tified which identifies oûe or more signiÊcant effects on the environment that would occur if the project is ap- proved or carried out unless both of the following occur: (r) The public âgency makes one, oi more, of the following findings with respect to each significant effect: (1) Changes or altetations have been required in, or incorporated into, the project which mitigate or avoid the significant effects on the enviroûmett. Ø 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 fot the provision of employment opportunities for highly trained wotkers, make infeasible the mitiga- tion measures or alternatives identified in the environmental irnpact report. þ) \With respect to significant effects which were subject to a finding under paragraph (3) of subdivision (a), the public agency finds that specific overiding economic, legal, social, technological, or other benefits of the proiect outweigh the sigrrificant effects on the environment. The Revised Environmental Impact Report ("REIR") for the Project (State Clearinghouse No. 2010712042) identifies sigrrificant or potentiâlly significant environmental impacts which, prior to mitigation, may occur as a result of imple- mentation of the Project. Trus, in accotdance with the provisions of CEQA, the Town of Danville, as the "lead agency" hereby adopts these Findings. L.2 Envitonmental Rcview Ptocess In conformance with CEQ,A., the Town of Danville conducted an environmental review process on the Project. The environmental review process included the following: 144459224.1 I-1 DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF I Relationship to 2013 EIR: In June 2013, the Town certified an Environmental Impact Report for and approved SummerHill Flomes' applica- tions fot 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 inadequatel¡' addressed impacts to traffic, bicycle safety, pedestrian safety, Califomia redlegged 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 traffrc impacts, and should have been recirculated fo¡ public comment. Finally, the lawsuit alleged that the project was inconsisrent 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 proiect could be approved. The only claim that prevailed in the litigation was that the EIR did not adequately address impacts to bicycle safety. Äs 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 2073 project pending further CEQA review on this issue. In Febrrrary 2017,Davrdon Flomes became the project âpplicânt. Davidon llomes revised the Project ptoposal to reduce developed area arrð. correspondingly increase protected open spâce by approximately nine âcres; to replace, rather than remove, the existing corral on the site; to include an electric vehicle charging staúon on each residential lot; and to include as Project elements certain requirements that had been imposed as mitigation measures 1fi 2073. In August 2077 , 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 2073 EIR's analyses of other aspects of transportation and circulation, as well as air quality, greenhouse gas emissions, noise, and energy. ,\s to all other environmental topics, the NOP/Checklist explained that the analysis in the 2013 EIR remained applicable to the Project. .) Scoping Ptocess: The Town of Danville prepared the NOP for the Project in accordance with $15082 of the CEQ-A. Guidelines. The NOP was distributed for public review on August 29,2017. Environmental issues raised by commeflts received in response to the NOP during its 30-day public review period (Ä.ugust 31 - Octob er 2,2018) *"." .orr.ìd"red for in- clusion i¡ the Dtaft REIR. Public and agency comments received on the NOP were reviewed and addressed in the Draft REIR. r) Preparation of a Dtaft REIR by the Town of Danville: The Draft REIR was distributed to Responsible Agencies, other affected agencies, and intetested parties. The No- tice of Completion (1.{OC) of the Draft EIR was distributed as required by CEQ-A, including publication of notice n the San Ranon Valle1 Times on Âugust _ 2018. The 45-day public review period began on -August 3I,2018 and ended on October 15,2018. During the public review period, the Draft REIR, including appendices, was made available and circulated fot public review. t Public Hearing on the Dtaft REIR: A public hearing was held by the Town of Danville Planning Commission on September 25,2018 to receive public commeflt on the Draft R-EIR. The Town responded to all envitonmental questions submitted verbally or in writing in the Final REIR. 144459224.1 l-2 DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF ,a o Pteparation of the Final REIR: Pursuant to Public Resources Code $21092.5, the Town prepared the Final REIR in response to comments on the Draft REIR. The Final REIR contains the following: refinêments and clarifications to the Draft REIR; written comments received on the Draft REIR; responses to those comments; and testimony presented to the Planning Commission and responses thereto. The Final REIR was issued on May 16,2079. 2.0 PURPOSEANDBACKGROUND 2.1 Desctiption of the Ptoject The Project evaluated in the Draft REIR consists of development of a 470 acte property currently referred to as Magee Ranches (Àdagee !7est and Magee East) in the Town of Danville. Magee lWest extends east of McCauley road just south of the intersection of Diablo/McCauley Road and South of Diablo/Blackhawk Road east of the Diablo McCauley intet- section. Magee East lies south of Diablo/Blackhawk Road, toughly between Jillian '$Øay 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 steepet slopes and ridges. The temaining * 381 acres of the site would be.preserved as new permâflent open space. A minimum of L}o/o of the homes would in- clude second dwelling units in accordance with the Town's Inclusionary Housing Ordinance. The Proiect 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: r) Develop a residential proiect that is consistent with the Town of Danville Agricultural, General Open Space, Rural Residential, and Single Family-Low Density General Plan Land use desþations for tlre site as well as the General Plan's Magee Ranch Special Concern Area langu.age O Provide 69 residential lots, including 66 home sites at the east ånd of the site south of Blackhawk Road and 3 homes home sites near the southeast corner of the Diablo Road/McCauley road intersection, O Desþ the project to cluster development on the lower portions of the site to minimize visual impacts and limit dis- turbance on the property, t Provide for a minimum of 10o/o of the 69 lots to include a second dwelling unit ("casita") to satisfi the Town's af- fordable housing requirements, O Preserve approximately 381 acres of the project site as permanent open space, and o Preserve significant features of scenic hillsides and majot ddgeline areas. The obiectives have been updated from those stated in ¡he 2013 Final EIR to reflect the Ptoject's increase in permanent open space kom372 to 381 acres. 2.2 Purpose of the REIR Pursuant to CEQA, ?ublic Resources Code sections 21000 et seq., ând 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.A,ugust 37,2018 and ending on October 75,2018. Responses to comments were ptepâred and are contained in the Final REIR. The REIR includes 144459224.1 I-3 DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF Âppendix -4, 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 issires othet than bicycle safety, and Energy. 2.3 Desctiption of the Record Fot 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 Dtaft REIR and all appendices to the Draft REIR; 3) The Final REIR and all appendices to the Final REIR; 4) All notices, staff repotts, and presentation materials related to the Projecg 5) All studies and reports conducted for the Project which are contained in, or referenced by, staff reports, the Draft R-EIR, or the Final REIR; 6) All public reports and documents related to the Ptoiect ptepared fot the Town and other agencies; 7) All documentary and oral evidence received and reviewed at public hearings and workshops and âll trafl- scripts and minutés of those hearings related to thê Project, the Draft REIR, and the Final REIR; 8) For documentary'and informational purposes, all locally-adopted land-use plans and ordinances, including, u¡ithout lirnitation, specific plans and ordinances, mâstet plans togethet with environmental review docu- ments, findings, mitigation monitoring progïams and other documentation relevant to plaqned growth in the ate ; 9) Any proposed decisions or findings or statemeflts submitted to the decision makers by staff or othèts; 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 considetations; n) The Reco¡d of Proceedings for the 2013 EIR; and 12) Any additional items not included above, if they ate required by law. 2.4 DisctetionaryActions The discretionary action for the Project involves the following approval by the Danville Town Council: 1) 2) Certification of the REIR for the Ptoject Approval of: ¡ Preliminary Development Plan and Final Development Pl¿n to tezoÍ7e apprcximately 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 (IR-10-0028) ('Tree Permit"). t-4 144459224.7 DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF These Findings are made by the Planning Commission pursuânt to $15091 of the CEQ,\ Guidelines. The Planning Commission is also recommending the adoption of a Statement of Overiding Considerations pursuant to $15093 of the CEQA Guidelines. 3.0 GENERAL FINDINGS 3.1 Terminology of Findings CEQÀ Guidelines 515091 requires that, for each significant environmental effect identified in an EIR for a proposed project, the approving âgency must issue a written fittditrg reaching one or more of three allowable conclusions. The first is that "[c]hanges ot 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 potentiâl 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 ot can and should be adopted by such other agen- cy." The third petmissible conclusion is that "[s]pecific economic, social, or other considetations make infeasible the mitigation measures or project alternatives identified in the final EIR." For purposes of these Findings, the tern "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 altetnatives to reduce an otherwise signiûcant environmental effect to a less-than-significant level. In the process of adopting any mitigation, the Town wpuld also m¿ke decisions on whether each mitigation measure proposed in the Dnft REIR is feasible or infeasible. Pursuant to the CEQA Guidelines, "fe¿sible 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." (CEQÄ Guidelines, 515364.) When the Town finds a measure is not feasible, evidence for its decision will be provided. 3.2 Cettification of Envitonmental Impact Report and Adoption of Findings On May 28,2019, the Planning Commission of the Town of Danville recommended certification of the EIR to tlle Town Council and approval of the Project (R.esolution 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" fot 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 tesult 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 ateas in Chapter 4 and -Àppendlr -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, preseût, and reasonably foreseeable future projects v/ere considered in the REIR as required by CEQA (Public Resources Code $21083) and the State CEQ,\ Guidelines (Cal. Code of Regulations,Title 14, $15130). The cu- mulative anâlysis 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 âreas to the extent required in order to determine the significance of the Project's inctemental 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-atJarge in their consideration of the environmental consequences of the Project. The pub- Iic review period provided all interested jurisdictions, agencies, private organizations, and individuals the oppor- 744459224.7 I-5 DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF tunity to submit comments tegarding 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 rriade at, or prior to the noticed public meetings and/or public hearings on the issues televant 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 CEQ,{, the Town prepared written responses describing the disposition of significant environmental issues raised. The Finat REIR provides adequate, good faith, and rea- soned responses to the comñents received by the Town. The Town has reviewed the comments teceived and re- spoflses the¡eto and has determined that neithet 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 $21092.1 and CEQA Guidelines $15088.5. Specifrca\, 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 ot reconìmeflded mitigation measufe; 2. Â substantial increase in the severity of an environmental impact that is not teduced to a level of less than significant by adopted mitigation measrues; 3. A feasible Project altemative or mitigation meâsure not adopted that is considetably different frqm oth. erc analyzed in the Draft REIR tlat would clearþ lessen the sþificant environmental impacts of the Project; or 4. Info¡-ation that indicates that the public was deprived of a meaningful oppo*unity to review and commert on the Draft REIR. The Planning Comrnission 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 aralyzedin the REIR. 3.6 These Findings are based upon substantial evidence in the entire record before the Town as described in Sec- tton 2.4. 3.7 The references to the Draft REIR and Final R-EIR 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 independentþ 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: 744459224.7 t-6 DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF I California Department of Fish and Wildlife (CDFG) ) CaLfornta Regional lVater Quality Control Board @ì7QCB) o San Francisco Bay Regional l7ater Quality Control Board (SFBRWQCB) a U.S.,\rmy Coqps of Engineers (,\COE) a U.S. Fish and l7ildlife Sewice (JSFWS) 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: t East Bay Municipal Utilities District (EBMUD) a Contrâ Costa County Flood Control and lù7ater Conservation District (CCCF!øCD) o Contra Costa Local Agency Formation Commission (i-AFCo) r) East Bay Regronal Patks District @BRPD) I Contra Costa County Because the Town of Danville is the lead ^geflcy for the Project, the EIR which the Town has prepared is intend- ed to be the basis fot compliance with CEQA fo¡ each of the possible discretionary actions by other agencies to caffy out the Project. 3.IL In several comments oû the Drâft REIR, various measures u/ere suggested by commenters âs proposed additional mitigation meâsures. Most of the proposed mitigation meâsures were for impacts that were less than significant. Based on the explanation and anaþsis in the REIR, these requests for additional mitigation measures ate declined. 3.72 Having received, reviewed, and considered the above described information, as well as all other information and documents in the record, the Planning Commission heteby finds as stated in these Findings. 3.73 Pursuant to Public Resources Code $21081.ó and California Code of Regulations, Title 14, $15091, the Town of Danville is the custodian of the documents and other material that constitute the record of ptoceedings upon which the Town's decision is based, and such documents and other rnatenal are located at: Town of Danville De- velopment Services Department, 570 Lz Gonda !lay, Danvill e, Califolirria,94526. 4.0 FINDINGS REGARDING POTENTIALLY SIGNIFICANT IMPACTS AND MITIGATION MEASURES The REIR identified potentially significant impacts in the areas identified below. The REIR tecommended mitigation meâsures to reduce all potentiaþ significant impacts to a level of insignificance. All of these mitigation measures were also identified jn the 2013 EIR; some have been modified to reflect Project changes (e.g., 381 rather than 372 acres of pemaûent open space) or feedback from agencies (e.g., EBMUD). Several mitigation meâsures identified in the 2013 EIR are not included in the REiR either because they have been incorporated into the Project Description ot because they are no longet applicable to the Project as revised. 4.1 Aesthetics Impact:The ptoject would create new sources of light that would adversely affect nighttime views in the area. Mitigation Measute 4.1-1 All buildings shall be designed so that teflective 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 tequirements: 1) exterior lighting shall be direc- 744459224.7 r-7 DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF tiotzl;2) the source of dkectional lighting shall not be directly visible; and 3) vegeta- tive screening shall be installed, where appropriate. Finding: The Planning Commission tecommends the adoption of Mitigation Measure 4.1-1. Based on the explanation and analysis in the REIR, the Planning Commission Ênds that with the adoption of the Measure, the impact on aesthèt- ics as described above will be mitigated to a less than signiFrcant level. 4.2 BiologicalResources Impact:Consttuction of the proposed subdivision could tesult in potential impacts to Califomia ted-legged ftog. 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 propoflent shall retain a qualiñed biologist to train all construction personnel regarding habitat sensitivity, identification of special status species, and re- quired practices. Prior to the start of construction, the project proponent shall retain a qualified biologist to conduct pre-construction surveys to erìsrüe 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 tlre construction ^re oî their own. c.Immediately following the pre-construction surveys and a determi- nation that CRLF are flot present in the constnrcúon zone, the con- struction zone shall be cleated and silt fencing erected and main- tained around construction zofles to prevent CRLF from moving into these areas. The project proponeflt shall retain a qualified biological monitor to be present onsite during times of coflstrrlction within the npanan habitat of East Branch Green Yalley Creek to ensure no CRLF are harmed, injured, or killed during project buildout. Mitigation Measute 4.4-2 The project would impact approximately 0.3 acres of moderate-quality ripanar. habitat resultìng from construction of the vehiculat 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 desþ phase.) Tlus shall be accomplished by restoring riparian habitat ¿t the four foltowing locations: ^. 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- b. d. 144459224.1 t-8 DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF ered to restore the natural flow ofthis portion ofthe creek. The existing crossing from San Andreas Drive shall be removed and the creek restored in this area. The two existing cattle grates on Magee West near the eústing cul- verts shall be temoved.' One of these is causing sediment build up and adversely impacting the cteek. The natural flow of this channel shall be restored back to its original condition prior to the original installation oI the gtates. The ripatian coridor along the East Branch of Green Valley Creek will be enhanced with suitable plantìng and placement of riparian vegetation along the proposed trail on Magee East. Âpproximately 2 acres along East Branch Green Valley Creek between the cteek and the trail is available to accomrnodate the minimum 0.3 acres of nparian enhancement plantings. The enhancement area shall be planted with native species appropriate for the cotridot. The project would impact approximateþ 0.5 acres of jurisdictional watets thzt arc of a degraded quality and matginal 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 ^cteage ratio. The final mitigation amounts will be based on actual im- pacts to be determined duting the design phase. Habitat teplacement via creation of andf ot enhancements to existing waters shall occur onsite. Onsite lands proposed to be preserved âs open spâce âre within the same watemhed as the offsite detention ba- sin known to support breeding CRLF and are expected to firlly accommodate creation of arrðf 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 associ¿t- ed riparian habitat between the stock pond and the detention basin. @efèr also to mitigation measures 4.4-73 and 4.4-14 below for impacts to jurisdictional watets.) The project proposes to preserve apptoximately 381 acres of the site âs open sPace. Areas to be preserved would be placed under a conservation easement or deed re- striction to prohibit coflstruction and preserve conservation value. The proiect pro- poses to create ^ geologic hazard abatement district (GHAD) to provide suitâble fund- ing for maflagement and long-term maintenance of the site. Upland habitats shall be managed via a long-term management plân to maintain the quality of the habitat fot the movement and dispersal of CRLF. Prior to construction, the project proponent shall retain a qualifìed biologist to prepare ân operl space management Plan for the explicit pulpose 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 gading permits. At â minimum this plan shall include the following components: ^. Identify the location of the restoration efforts for replacing jutisdictional waters and npanzr habitats. The replacement ratio for both habitats will be at a minimum of a 7:7 ntio. b. Identi$r 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 ptoposed enhancement. b. c. d.

Identi$r a suitable planting regime for restoring wetland and ripanan habitats. d. Identify success criteda for monitoring both the wetland and riparian habitats that are consistent with similar habitats tegionally. e. Monitor restored wetland habitats for at least ltve years and iestored ri- parian habitats for 10 years. f. Define and identi$r the GFIA.D 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 catùe grazing or other proce- dures to manâge 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 peqpetuity. Finding: The Planning Commission recomrnends the adoption of Mtigation 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 Measutes, the impacts on biological resorrces as described above will be mitigated to a less than significant level. Impact:Consuuction of the ptoposed subdivision could result in potential impacts to westetn pond turtle. Mitigation Measute 4.4-5 Implementation of the avoidance, minimization, and compensation measures for the CRLF (see discussion above) would address impacts to westero pond turtles. The proiect proponent shall also implement the following measures. Prior to the start of construction, the ptoject proponent shall retain a qualified biolo- gist to train constructiori 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 Bnnch Green Valley Creek riparian atea, fhe project proponent shall retain a qualifred biologist to conduct pre- construction surveys to eflsure that western pond turtles are absent ftom the coristruc- tion atea. Ifwestem pond tutles are present, a qualified biologist possessing all neces- sary permits shall be retained to relocate them. Mitigation Measute 4.4-7 If westem pond turtles are found to be absent from the construction zone, immediate- ly following the pte-construction surveys the proiect proponent shall clear the con- struction zonle ard install/maintain silt fencing around the constructiofi zoîe to pre- vent westetn pond turtles from entering these areas. Mitigation Measute 4.4-8 During construction within the East Branch Green Valley Creek ripadan area, the project proporert shall retain a biological monitor to be present onsite during times of construction to ensure that turtles âre not harmed, iniured, or killsd. Finding: The Planning Commission recommends the adoption of Mtigation Measures 4.4-5 through 4.4-8. Based on the explanation and anal¡'sis 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. 144459224.7 I-1 0 DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF Impact:Construction of the proposed subdivision could tesult in potential impacts to nesting raptors and migratory bitds. Mitigation Measute 4.4-9 To the maximum extent practicable, the project propoflent shall remove trees during the non-breeding season (September 1 thtough 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 proporrent shall retain a qualiÊed biologist to conduct a pre-coflstruction survey for tree-nesting raptors and other tree- or ground-nesting migratory birds in all tees or other areas of potential nesting habitat within the con- struction footprint and 250 feet of the fooçrint, if such disturbance would occut dur- ing the breeding seâson. This survey shall be conducted no more than L4 days prior to the initiation of demolition/construction activities during the earþ part of the breeding season @ebnrary through April) and no more than 30 days prior to the initiation of these activities during the late part of the breeding season (À4ay through ,{'ugust). If nesting raptors or migtatory 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 buffet (a minimum of 150 feet up to a maximum of 250 feet) shall be determined at th¿t 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 ar'd are independent of their par- ents. Pre-construction surveys during the non-breeding season are not necessâq/, âs the birds are expected to abandon thei¡ roosts during construction activities. Finding: The Planning Commission recommends the adoption of Mtigation Measwe 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 resoutces as described above will be mitigated to a less than significant level. Impact:Construction of the proposed subdivision could tesult in potentiâl impacts to butrowing owls. Mitigation Measute 4.4-10 In order to avoid impacts to active burrowing owl nests, the project proponent shall rctairt a qualified biologist to conduct pre-construction surveys for burrowing owls within the construction footprint and within 250 feet of the fooçrint no more than 30 days prior to the onset of ground disturbance. These surweys shall be conducted in a nrânner consistent with the CDFG's burrowing owl survey methods (CDFG 2012b). If pre-construction surveys determine that burrowing owls occupy the site dudng the non-breeding season (Septembet 1 through January 31), then a passive relocation ef- fot (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 gtound distutbance can proceed. Ifburrowing owls are detected within the construction fooprint or immediately adjacent lands (i.e." within 250 feet of the footprint) during the breeding season (February 1 through 'August 3i), â 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 mây not enter the enclosed setback areas. Buffets must remain in place for the duration of the breeding season or until it has been confitmed by a quali- fied biologist that all chicks have fledged and a:te independent of their parents. After the breeding seâson, passive relocation oÍ any remaining owls may take place as de- M445q224.1 I-1 1 DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF scribed above. Finding: The Planning Commission recommends the adoption of Mitigation Measure 4.4-70. Based on the explana- tion and analysis in the REIR, the Planning Commission finds that u¡ith the adoption of the Measure, the impacts on biological resources as described above will be mitigated to a less than significant level. Impact:Constuction of the ptoposed subdivision could result in potential impacts to Ametican badgets. Mitigation Measure 4.4-11 Pre-construction surveys conducted for burrowing owls shall also be used to deter- mine the plesence or absence of badgers in the development footprint. If an active badger den is identifred during pre-construction surveys within ot immediateþ adja- cent to the constnrction envelope, the ptoiect 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 Írest abandonment. The monitor shall be present onsite until it is deter- mined that young âre 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 collap.sed or excavated, and gtound disturbance.can ptoceed. 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 tlre 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 ptoposed subdivision would impact wetlands (0.5 actes) and riparian habitat (0.3 actes). Mitigation Measute 4.4-12 The project proponent shall teplace 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 ptoposed as open space. Pdor to issuance of a grading petmit, the project, proponent shall tetain a qualified biologist to prepâre an onsite habitat mitigation and monitoring plan (HMUI) that includes both an aquatic habitat restoration plan and a npanan 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 Mitigaúon 4.4-4, although there may be some ovedap. The HMMP shall include the following components, at a minimum: ^. Define the location of all restoration/cteation activities; b. Ptovide evidence of a suitable water budget to support any created wet- land and ripzriar habitats; c. Identify the species, amoufl.t, and location of plants to be installed; d. Identi$' the time of yeat for planting and method for supplemental wa- tering during the establishment period; e. Identify the monitoring period, which should be not less than 5 years for wetland testoration and not less than 10 years for riparian restoration, defines success criteria that will be required for ihe wetland restoration to be deemed a success; f. Identify adaptive manâgement procedures that include þut are not lim- 144459224.1 r-12 DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF ited to) meâsures to address colonization by invasive species, unexpected lack of water, excessive foraging of installed wetland plants by native wildlife, and similar; C. Define management and maintenance acùvities (weeding of invasives, providing for supplemental water, repair of water delivery systems) of the ptoposed GFIAD; and h. Provide for assutance 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 GI{AD v/ill meet these responsibiJities. Mitigation Measute 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 proponeût sh¿ll obtain a Section 404 Clem'V7ater Act permit from the USACE, Section 401 \7atet Qualiq' Certification from the Rì7QCB, andf or Section 1ó00 Streambed Alteration Agreement from the CDFG, and submit proof of such documentatìon to the Town of Danville. Finding: The Planning Commission recommends the adoption of Mitigation Measutes 4.4-T2through 4.4-13. Based on the explanation and anaiysis 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 ptoject would tesult in the temoval of 49 üees on the site, which reptesents 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 meâsures to be taken and includes the tree preservation guidelines by HortScience in their tree report(s). These measures shall remain in place for the dutation of construction aitivities at the project site. Mitigation Measute 4.4-15 Upon completion of construction, the ptoject proponent shall replace all ordinance- size trees to be removed with approved species "of a cumul¿tive number and diameter necessâry to equal the diameter of the tree(s) which are approved for removal" in ac- cordance with the Town's. tree t¡rdin¿nce. Ttee 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. AII non-native trees that are removed shall be replaced with species that are known to occur naturally within sirnilar habitats in the region. Mitigation Measure 4.4-16 Prior to construction, the project proponent shall retai¡ 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 ûnal success criteria, specifrc performance criteria, monitoring methods, data analysis, monitoring schedule, conúngency/remedial measures, and 144459224.7 1-13 DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF fepofung fequrements. Finding: The Plaining Commission recommends the adoption of Mitigation Measures 4.4-14 through 4.4-76. Baseð 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 wj.ll be mitigated to a less than significant level. Impact:The imptovements to the Diablo Road/Gteen Valley Road intetsection would requite the temoval of 18 tees within the Town tight-of-way, which represents a significant impact. Mitigation Measure 4.4-17 The Project shall implement Mitigation Measures 4.4-14 thtough 4.4-76 as applicable. Finding: The Planning Commission recommends the adoption of Mtigation Measure 4.4-11 . Based on the explana- tion and analysis in the REIR, the Planning Commission finds that with the adoption of the Measute, the impacts on biological resources as described above will be mitigated to a less than significant level. 4.3 Cultutal Resoutces Impact:Consttuction of the ptoiect may tesult in the discovery and disturbance of un- ftnown atchaeological tesoutces and/ot human remains. Mitigation Measure 4.5-1 If during the course of project construction, archaeological resources or human re- mains are accidentaþ discovered during construction, wotk 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 docurnentation to the Town indicating that discovered resources have been adequately salvaged and no fur- ther resoutces have been identified witlin the area of disturbance. Mitigation Measute 4.5-2 Pursuant to Section 7050.5 of the Health and Safety Code and Section 5097.94 of the 'Public Resoutces Code of the State of Califomia, 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 neatby area reasonably suspected to ovedie adjacent remains. The Contra Costa County Coroner shall be notifred 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 noti$r the Native Ämerican Heritage Commis- sion who shall attempt to identi$r descendants of the deceased Native American. If no satisfactory agreement can be reached as to the disposition of the remains pursuânt to this State law, tlren the land owner shall re-inter the human remains and items asso- ciated with Native American burials on the property rna location not subject to fur- t]ler subsurface disturbance. Finding: The Planning Commission recommends the adoption of Mtigation 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:Consttuction of the ptoject may result in the discovery and disturbance of un- known paleontological tesoutces. Mitigation Measute 4.5-3 If during the course of project construction, paleontological resources are accidentall¡' 744459224.1 I-14 DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF discovered during construction, work shall be halted within 20 feet of the find until a qualified professional paleontologist can evaluate it. \ùíork shall not recommence untjl the project paleontologist has submitted documentation to the Town indicating that discovered resources have been adequately salvaged and no furthet resoutces have been identiFred within the area of disturbance. Finding: The Planning Commission tecommends the adoption of Mitìgation 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 sigruficant level. 4,4 Geotechnical Impact 4.6-1 Construction of the proiect could tesult in temporary soil etosion and loss of topsoil Mitigation Measute 4.6-1 In order to reduce wind and water erosion on the project site, an erosion control plan and Storm rùØater Pollution Prevention Plan (SWPPP) shall be prepated for the site preparation, construction, and post-construction periods (see mitigation measute 4'8-1 in 4.8 Hydrology and Watet Qualiry). The project 5þ¿lì prepare an etosion control plan in accordance with the Town's Eto- sion Control Ordi¡ance. The ptoject proponeût shall implement the. following measures, where appropriate, to cottrol etosion: 1) keep constructioû 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 priot to development, which should be strictly ob- sewed; 3) utilize mechanical measures (i.e., walls from sand bags and/or woodeû slat or fabdc fences) to teduce sand movemenq 4) immediate re-vegetation þlus the use of temporary stabiJizing 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 etosion control plan shall be submitted to the Town of Danville for review and apptoval prior to issuance of a grading permit. Finding: The Planning Commission tecommends the adoption of Mitigation Measure 4.ó-1. Based on the explanation and analysis in the REIR, the Planning Commission finds that with the adoption of the Measute, the impacts orr ge- otechnical as described above will be mitigated to a less than significant level. 4.5 ]f{azatds & Ffazatdous Matetials Impact:Development of the ptoposed proiect, including excâvation and other land dis- turbãnce, could tesult in the telease of hazatdous materials that may be ptesent orr portions of the proiect site, exposing consttuction petsonnel and the envi- rofrment to potential health and safet5r risks. Mitigation Measure 4.7-1 In order to minimize potenúal human healthhazatds associated with the historical use of hazardous materials on portions of the proiect site, the ptoiect proponent shall re- tain a trained professional to prepare a Site Management Plan to maifltâin the safety of construction workers and assure propet mân¿gement of any contaminated soils on the site in accotdance with fedetal, state and local regulatory requirements. This plan shall 144459224.7 I-15 DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF be subject to review and approval by Contra Costa County Health Sewices, and evi- dence of approval ptovided to the Town of Danville, priot to the issuance of any grz'd- ing permit, demonstrating that all necessâry remedial actions have been completed pursuânt to the approved Site Management Plan. -At a minimum, the Site Manage- ment Plan shall include 1) the collection ^nd chemical analysis of soil samples from the former UST location and 2) excavation and soils characteÅzatfo¡ to confìrm that suf- ficient soils removal has occurred for OCPs and elevated 4, 4-DDE at location SB-3, and 3) proper temoval and disposal of all hazardous matedals on the site, including contaminated soils, chemical containers observed in the storage shed, and herbicides spray bottles ât ân approved disposal facility. Finding: The Planning Commission recommends the adoption of Mitigation Measure 4.7-1. Based on the explanation and anaþsis 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 Hydtology & Water Quality Impacû Consttuction aûd operation of the ptoiect could impact surface watet quality. Mitigation Measute 4.8-1 In order to avoid water quality impacts, a Storm llater Pollution Prevention Plan (SWPPP) shall be prepared for the site preparation, construction, and post- coflstmction periods. The SWPPP shall incorporate best mânâgement practices con- sistent with the requirements of the National Pollution Discharge Elirnination System G\fPDES) Municipal Stormwater petmit (l'{o. C4S612008). The project proponent shall obtain a NPDES General Construction Permit and prepare the S!7PPP in ac- cordance with all legal requirements, prior to the issuance of a grading permit. ,\ddi- tional requirements for erosion control are detailed in mitigation meâsure 4.6-I tfl 4.6 Geotechnic¿l 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 Measu¡e, 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 tesult in an inctemental inctease in the student poPulation in the SRVUSD. Mitigation Measute 4.11-1 The applicant shall pay a school impact fee pursuant to the criteria set fotth within California Government Code Section 65995. Prior to the issuance of building permits, the applicant shall pay required school mitigation fees, subject to the tevieu¡ and ap- proval of the Town of Danville and San Ramon Valley Unified School District. The fees set forth in Govemment 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)]. 144459224.1 t-16 DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF Finding: The Planning Commission recommends the adoption of Mitigation Measure 4.lt-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 public services as described above will be mitigated to a less than signifrcant level. 4.8 Transportation & Citculation Impact:The project trips added to the intetsection of Diablo Road/Blackhawk Road & Mt. Diablo Scenic Boulevard undet Existing plus Ptoject and Cumulative plus Project Conditions will increase the V/C tatio by more than 5 petcent during the AM and School PM peak hours, which constitutes a significant impâct based on the established thtesholds ofsignificance. Install a traffic sþal 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 ,\ or B under all scenatios. Mitigation Measure 4.3-1 Finding: The Planning Commission recommends the adoption of Mtigation Measure 4,12-t. Based on the explana- tion and anaþsis 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 Comrnission further finds that Mtigation Measure 4.3-1 is v¡ithin the responsibility and jurisdibtion of Contra Costa County and not the Town, and that the County can and should adopt this Measute. If the County does not adopt this Measure, this tr¿ffic 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 ptoposed project would tequire the consttuction of new watet inftastructure in otdet to serve the proiect. EBMUD has identified that specific imptovements may be necessary to setve nevr' uses. These imptove- merits are necessâry to mitigate potential water supply infrasttucture impacts. Mitigation Measure 4.13-2 Prior to the tecordation of the final map for each phase of development, the applicant shall submit detailed desþJevel infrastructute drawings approved by the East Bay Municipal Utility District to the Town of Danville fot review and approval. All new water supply infrastructure shall be desþed in accordance with all applicable East Bay Municþal Utihty District specifications. Alì water supply inftastructure plâns shall be teviewed and approved prior to final map recordâtion. Mitigation Measute 4.13-3 The East Bay Municipal Utility District maintains a right-of-way ß/W 1581) through the project site, which provides access to the Green Valley Reservoir. Iu order to avoid potential effects to East Bay Municþal Utitity District's existing operations, the final map shall clearþ delineate all known easements, including East Bay Municipal UtiJity 1 44459224.1 t-17 DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF District's right-of-way ß/W 1581). Any and all activities proposed within the right-of- way shall be coordinated v¡ith East Bay Municþal Utility District. This easement shall be reflected in all final desþ-level improvement plans and appropriate notes shall also be included, subject to the ¡eview and apptoval of the East Bay Municipal Utility Dis- trict and tle Town of Danville. Finding: The Planning Commission recommends the adoption of Mitigation Measures 4.73-2 and 4.13-3' Based on the explanation and analysis in the REIR, the Planning Commission finds that with the adoptìon of these Measures, the impacts on utilities as described above will be mitigated to a less than significant level. 5.0 FINDINGS RELATED TO CUMUI-ATIVE IMPACTS AND MITIGATION MEASURES CEQ,{ Guidelines require consideration of the potential cumulative impacts that could result from a proposed ptoject 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 othet environmental consequences. An explanation of the cumulaúve impact analysis is in Section 5.2 of the Draft REIR. One significant cumulative impact was found for the Ptoject, in the area of ttafftc congestion. This cumulative impact can be mitigated to a level of insignificance as discussed above. If the County declines to adopt Mtigation Measure 4.3- 1 (sþalization of the Diablo Road/Blackhawk Road & Mt. Diablo Scenic Boulevard intersecúon) then this impact will be significant and unavoidable. There is no evidence in the tecotd to indicate the County vuill not adopt the Measure. Flowever, a Statement of Overiding Considerations is included in Section II in response to that unlikely scenado. 6.0 FINDINGS REGARDING MONITORING OF MITIGATION MEASURES In order to ensure that the mitigation meâsutes identified herein are implemented, the Planning Commission recom- mends the adoption of the Mitigation Monitoring and Reponing Program i¡clude with the Project approvals. 7.0 FINDINGSREGARDINGÁLTERNATIVES CEQA Guidelines $15126.6 requires a discussion of a teasonable range of alternatives to the project ot to the location of the project. However, an EIR need not consider an alternative whose implementation is remote or speculative. -A'n EIR is required to describe and comparativeiy evaluat e ^ t^îge of reasonable alternatives to a project, or location of the pro- ject, that would feasibly attain most of the basic objectives of the project but would avoid or substantially lessen any of the significant effects of the ptoject. Thus, the range of alternatives evaluated in the Draft REIR was dictated by CEQA and by the range of significant impacts identified in the D¡aft REIR, and evaluated alternatives were limited to those that theoretically could have reduced or eliminated identified environmental impacts. The Draft R-EIR also considered and reiected two alternaúves from further considetation. First, an alternative location wâs not carried forward for analysis since there is no other site that cafl âccommodate the Project and implement the criteria specified in the General Plan that identi$r the Project site as an Area of Special Concem. 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 iots would increase fooçrint impacts compared to the Proposed Ptoject; and the number of residential lots in tlis alternative (66) was virtually the same as the 69 lots in the proposed Project and i¡ Alternative 3. T'he Draft REIR discussed the following altematives in detail: 7. No Project/No Build 144459224.1 I-1 I DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF 2. No Project/Build without Subdivision (7 residential lots) 3. More Clustered Altemative/Minimum 5,000 SF Lots (69 residential lots) 4. Non-Clustered Àlternative (78 residential lots, no zone change) F.ach of these altematives \¡/as ewaluated under the sa{ne environmental categories as presented fot the Project and as idenúhed in Chapter 4 and -Appendix Ä of the Draft REIR. Based on the comparison of the relative merits of each al- temative compared to the Project, each of the altematives was found to be deficient in meeting the Proiect's goals and objectives, and Altemative 4 would câuse greater environmental impacts. The Final REIR at pages 27-28, explains why altematives suggested by commentets would not meet project objectives, would not reduce environmental impacts, or both. These alternatives are: a) a reduction in tesidential 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 tOS E and F at z\M peak and School PM Peak hours, respectiveþ; b) nine 2}-acre parcels on land currently zoned Agricultural, with smâll clusters elsewhere on the site (which would spread development mote widely across the site, adding to visual impacts and failing to meet the project objecúve of extensive public open space); and c) elirnination of the three residential lots at Magee !7est (which would not avoid any significant traffic impact).The overall objectives of the Proiect are to: 0 Develop a residential project that is consistent with the Town of Danville Agdcultural, General Open Space, Rual Residential, and Single Family-Low Density Genetal Plan Land use desþations for the site as well as the General Plan's Magee Ranch Special Concem Area language, 0 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 coÍrer of the Diablo Road/McC¿uley road intersection, f Desþ the project to cluster development on the lower pottions of the site to minimize visual impacts and limit dis- turbance en the property, o Provide for a minimurn of 70o/o of the 69 lots to include a second dwelling unit ("casita'l) to satis$' the Town's af- fordable housing requirements, O Preserve approximately 381 acres of the project site as permanent open space, and o Preserve significant features of scenic hillsides and major ridgeline areas. 7.1 No Ptoiect/No Build Altetnative 7.L,1 Descdption of Altetnative 1 CEQA requires the discussion of the No Project Altemative "to allow decision makers to comPare the impacts of approving the proposed project with the impacts of not approving the proposed proiect." For the pu{poses of this analysis the No Project Alternative represents the "no development" scenario in which the site is left in its current generally undeveloped condition þer CEQA Guidelines Section 1512ó.6(e)(3) and existing ranching uses continuing to operâte. This alternative would eliminate the preservation of over 381 actes of the site in permanent open space, with public trails, proposed by the Project. 7.1.2 Rejection of Altetnative The No Project Alternative would avoid all of the environmental impacts of the proposed Project. The No Proiect 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 Proiect site under the proposed Proiect). The No Project ,\lternative is infeasible because it 144459224.1 I-19 DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF would fail to meet any project objectives, rncluding to build a residential community on the site consistent with the existing zoning and General Plan and preserve over 381 acres in permânent open spâce. The Alternative would not provide public access thtough a ftail system 7.2 Ptoiect/BuildWithoutSubdivision 7.2.1 Description of Alternative The No Project/Build Alternative consists of elirninating the proposed subdivision and developing the proiect site with one residential lot per existing parcel. Since the site currently contains seven buildable parcels, this altemative would result in the construction of a total of seven residential homes.on the site. This altemative would require the provision of infrastructure to each individual parcel, including roads, water, powet, 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 ovet 381 acres of the site in permanent open space proposed by the Project. 7 .2.2 Reiection 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 ó9-lot residential community on the site and preserve over 381 acres in permaflent operi space. 7.3 Mote Clusteted Alternative/Minimum 51000 S.F. Lots 7.3.1 Desctiption 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 fooçdnt than the proposed Project. This altemative 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 smallet fooçrint 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 Reiection of Alternative The 5,000 SF lot alternative would lessen some impacts of the Ptoiect 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 tralfrc congestion, the irnpacts would be unchanged due to the number of residential units. This altemative is rejected as infeasible because it would creâte an abrupt change in density compared to existing residential neighborhoods adjoining the project site. 7.4 Non-ClustetedAltetnative 7.4.1 Description of Alternative This alternative consists of the development of the project site with 78 lots, v¡ith most lots sized a minimum of five acres. This alternative comprises 67 ftve-acre lots on the portions of the site covered by the Town's Residential - Rural Residential or Public and Open Space - ,{gricultural General Plan land use desþations. The ftve-acre portion of the site covered with the Town's Residential - Single tramily - Low Density General Plan land use designation (opposite Fairway Drive) would contain 11 tots with a minimum size of 13,000 square feet. This alternative would eliminate the presewa- tion of over 381 acres of the site in permanent open spâce proposed by the Project. 144459224.7 I-20 DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF This alternative would not cluster development on the flatter portions of the site but rather develop the majority of the project site with five-acte "tanchettes." This altemative consists of 24 lots on Magee West and 54 lots on Magee East. The lot configuration under tlis altemative would not allow for pteservation of large'portio¡s of the project site in open space. This altetnative is being evaluated at the request of the community at the scoping meeting for the 2013 EIR, as well as because it is the t¡le 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 confotm to the Town's General Plan policies that recommend development be concentrated on the flatter less visjble portions of the site. 7.4.2 Rejection of Altetnative Tlris altemative is infeasible because it would increase environmental impacts compared to the proposed Project and would not meet proiect objêctives. This alternative u¡ould introduce non-clustered development on the entire site. This would result in substantially greater, significant aesthetic impacts due to viewshed alteration. It would result þ gleâter land dis¡rrbance impacts by requiring additional grading, an extensive roadway system, and additional proiect iflfrastruc- ture to provide service and access to each lot. The overall impacts of this altemative would be substantially greater than the Project. This altemative would not meet the Ptoject objectives to cluster development on the flatter portions of the site and minimize grâd;ng and infrastructure requirements. Moreover, the Project, as approved, includes fewet housing units. This alternative would not conform to the policy of the Magee Ranch Special Concern Area identified in the General Plan, which "sttongly discourages" subdivision of the ptoperty into s-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 currentþ per- mitted under the Town's 2010 General Plan and 2030 General Plan. The Project would not establish policies nor add inftastrucnrre which would induce furthet $o$/th in the vicinity 144459224.7 r-21 DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF SECTION II STATEMENT OF OVERRIDING CONSIDERATIONS 1.0 Inttoduction In determining whether to âpprove a project that creates significant and unavoidable impacts, CEQA Guidelines 515093 requires a public agency to balance the benefits of the project against its unavoidable environmental risks. The REIR identified mitigation measures that can reduce all potential environmental impacts to less than significant level. The Mitigation Measute to reduce the Ptoject's contribution to traffic at the intersection of Mt. Diablo Scenic/Diablo (À4easure 4.3-1), is within the tesponsibility 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 Conta Costa County will not implement this Measure. Rather, the letter from the County commenting on the Draft REIR (Comment Letter 1 in Final P.EIR) 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 reâson, a Statement of Overiding Considerations is ptesented. In accordance with Public Resources Code S2i081(b) and CEQA Guidelines 515093, the Planning Commission has, in determining whether or not to recommended approval of the Project, bal- anced the economic, social, technological, envitonmental, and other benefits of the Project against this potential una- voidable environmental effect, and has foi¡nd that the benefits of the Project outweigh this possibility, for the reâsons set forth below. This Statement of Overiding Considerations is based on the Planning Commission's review of the REIR and othet information in the administrative record. The Planning Comrnission finds that each of the following benefits is an overriding consideration, independent of the other beneñts, that watrants approval of the Ptoject notwith- standing the possibility of a significant unavoidable impact. 2.0 OvettidingConsiderations Substantial evidence is included in the record of these proceedings and in documents relating to the Project demonsftat- 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 4.3-7, and concludes that the economic, social and environmental benefits that will be derived from the Project outrweigh 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 Proiect is consistent with the goals and policies in the Town's General Plan, Zonttg Ordinance and other planning documents and provides a density of 69 units which is below the allowable density range of 78 units. r The Project implements the direction in the General Plan relating to contemplated development in the Plan- ning -A.rea/Special Concern ,\rea 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 pemânent open space. ¡ The Ptoject as conditioned will be required to make imptovements to the intersection of Diablo Road/Green \ra[ey 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 uflits will in- crease the housing alternatives available to home buyers and generâte economic activrty in the area. 012267.0006\3082006.1 'lhe Planning Center I DC&li 744459224.1 II-1 DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF The General Plan establishes the goal of providing affordable housing oppottunities. The Project will help meet these affordable housing needs by corstructirig 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 âçcess 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, overlide 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 inco¡porated into, the Project which mitigate or avoid tlie sig- nificant effects on the environment. Those changes or alterations ate 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. Specific economic, legal, social, technological, or other considerations, including conside¡ations 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. 1)All significant effects on the environment due to the approval of the Project have been eliminated or substan- tially lessened whete feasible. ,{,ny rcmaining significant effects on the envüonment 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 apptoved. a a a ,\ 3) Based on the foregoing findings ¿nd the information contained in the record, it is determined that: 2) 144459224.7 I-2 DocuSign Envelope ID: B7269F56-A20D-4829-92BF-C3AB8F5BDFBF DR A F T M I T I G A T I O N Mo N I T o R I N G AN D RE P o R T I N G Pn O C n ¡ N ¡ - MA G E E PR E S E R V E Ma y 20 1 9 NO T E S : Se c t i o n 21 0 8 1 . 6 of th e Pu b l i c Re s o u r c e s Co d e re q u i r e s al l st a t e an d lo c a l ag e n c i e s to es t a b l i s h mo n i t o r i n g or re p o r t i n g pr o g r q m s wh e n e v e r ap p r o v a l of a pr o j e c t re l i e s up o n an en v i r o n m e n t a l im p a c t re p o r t (E I R ) .
