The Tree Removal request would allow for the removal of two Town-protected Oak trees, each with diameters of 11 inches. There is an existing 2,900 square foot residence on proposed Lot D. EVALUATION/ DISCUSSION Conformance with General Plan and Zoning District The site has a General Plan Land Use Designation of Residential – Country Estates, which requires a minimum lot size of one acre. The parcel is zoned P-1; Planned Unit Development District, consistent with the requirements of the Lawrence/Leema Road Specific Plan. The upper, steeper portion of the site goes by R-100 (100,000 square foot parcel size minimum) zoning standards, and the lower, flatter portion of the site goes by R-40 (minimum 40,000 square foot parcel size minimum) zoning standards. Proposed Lot A is split between R-100 and R-40 zoning standards, the proposed parcel size of 95,803 square feet based on the proportion of the parcel in each zoning category. All the proposed parcels meet the minimum size requirements. Tree Removal An arborist report was prepared for this project by Brightview Tree Care Services (see Attachment C). Approximately 81 trees exist on the site, nine of which qualify as protected trees under the Town’s Tree Protection Ordinance. Two 11-inch diameter Valley Oak trees located to the right of the existing residence, which are in poor health are proposed for removal. Many of the existing non-Town-protected trees are proposed to be removed. Seven Town-protected Oak trees located on proposed parcel A would be preserved. 1610 Lawrence Road 2 September 22, 2020 C.3. Stormwater Control In compliance with the Town’s Stormwater Management and Discharge Control Ordinance, future development would be subject to compliance with the Town’s C.3 stormwater pollution control requirements as found in the Stormwater Control Plan. Individual stormwater treatment facilities are proposed for each of the four proposed parcels. The storm drain system would be required to be maintained by the homeowners through a maintenance agreement. The storm drain facilities would be inspected by the Town on an annual basis. Parcel Development As recommended through conditions of approval, the development of a single-family residence would be subject to review by the Design Review Board under separate Development Plan applications. Each residence, including the existing residence, would be required to connect to public water and sewer services. ENVIRONMENTAL REVIEW The project has been found to be Categorically Exempt from the requirements of the California Environmental Quality Act (CEQA) Section 15315, Class 15 (Minor Land Division). PUBLIC CONTACT Public notice of the September 22, 2020 hearing was mailed to property owners within 750 feet and posted online. A total of 26 notices were mailed to surrounding property owners. RECOMMENDATION Approve Minor Subdivision request MS 853-2019, and Tree Removal request TR20-0026 allowing for the subdivision of a 5.21 acre parcel into four single family residential parcels, subject to the findings and conditions of approval contained within Resolution No. 2020-07.

Tree Removal: 1.Necessity. Removal of the two Town-protected trees is warranted, in that they are in poor health. Removal of the trees will mitigate a potential hazard and allow for the reasonable use and enjoyment of the property. 2.Erosion/surface water flow. Removal of the Town-protected trees will not cause significant soil erosion or cause a significant diversion or increase in the flow of surface water, in that proposed site improvements and drainage improvements will stabilize the site and provide for proper storm water runoff. 3.Visual effects. Tree removal will not result in significant visual impacts, in that the project site and surrounding neighborhood contains a significant number of additional trees not effected by the development. In addition, the project proponent will be required to replace all Town-protected trees removed with trees of an approved species and of a cumulative number and diameter necessary to equal the diameter of the tree(s) which have been approved for removal in accordance with the Town’s Tree Preservation Ordinance.

APPROVED by the Danville Planning Commission at a special meeting on September 22, 2020, by the following vote: AYES: NOES: ABSTAINED: ABSENT: _____________________________ CHAIR APPROVED AS TO FORM: _______________________________ ______________________________ CITY ATTORNEY CHIEF OF PLANNING ATTACHMENT B Bob Peralta ISA Certified Arborist, WE-7150A BrightView Tree Care Services 4677 Pacheco Blvd Martinez, CA - 94553 925-525-3795 tel 925-957-8833 fax 1 May 27, 2019 Jeff Klaus Snagwood Corporation DBA Blue Sky Realty 3130 Balfour Road D #305 Brentwood, CA 94513 Subject: 1610 Lawrence Road Danville, California Dear Jeff, Thank you for asking me to provide a Consulting Arborist Report for 1610 Lawrence Road Danville California. I did a site inspection on May 22, 2019 to inspect all the trees on site. I used the Topographic Survey map provided to you by DeBolt Civil Engineering, dated 5/06/2019. The purpose of this report is to identify the species of trees, size, diameter (Dbh.), health and recommendations. The site I evaluated has an existing home, barn and large open area corral. The property is surrounded by 81 trees that consist of 17 different species. There are two species of trees that are native to the property, Valley oak (Quercas lobata) tree tags – 74, 75, 76, 77, 78, and 70, and Live oaks (Quercas agrifolia) tree tags 73, 80 and 81. All these trees are located on the hillside behind the home and all are in good health. The remaining 72 trees are along Lawrence drive, lining the driveway and around the corral. The eucalyptus, pine, willow trees and mulberry all appear to have been planted around the same time. The size and conditions are found in the reports listed below. Attachment (1) is a map that identifies the location, species and tag number of each tree. Attachment (2) is a spread sheet of each tree that identifies the tag #, species, height, dbh. (diameter), health, action and recommendation. Attachment (3) is a picture and location of each individual tree. The trees that line the street and driveway are (25) eucalyptus and all were planted at the same time. They have matured into large trees with poor structure, all of the eucalyptus have included bark where the branches are weakly attached to the trunk. As the trees continue to mature the branches eventually start to fail. There has been no visible preventative maintenance to the trees and all of the tree have deadwood and large cavities throughout the branches. I do recommend removing all of these trees for safety. The remaining (47) trees consist of domestic non-native trees that are in various stages of decline mainly due to lack of summer irrigation. A majority of these trees were planted in rows, between or behind the eucalyptus trees where lack of sunlight created a tall leaning tree with poor branch structure. Each tree listed on Attachment (2) have recommendations for preservation or removal.
