• Grade changes near or within the dripline of said oak trees shall comply with the following: o No grade changes shall occur within six (6) feet of the trunk of the tree. o No grade changes shall occur that entail removing or adding more than six (6) inches of soil in the protected zone of the tree. o Any grade changes within the protected zone of the tree shall be accomplished so as to prevent soil compaction and injury to or removal of the tree's roots. (Development Title Section 9-1505.5[a]) • Before grading operations may commence, a minimum five (5) foot high chain link fence or other comparable protective fencing shall be installed at the outermost edge of the protected zone of each tree or group of trees (Development Title Section 9-1505.5[b]). • No trenching whatsoever shall be allowed within the protected zone of subject trees (Development Title Section 9-1505.5[c]). • Paving within the dripline of affected trees shall be minimized. If paving is necessary, porous materials shall be used (Development Title Section 9-1505.5[e]). Endangered Species/Animal Life The Natural Diversity Database includes records for the California Tiger Salamander (Ambystoma Californiense). The presence of California Tiger Salamander on the site raises the concern of a potential environmental impact regarding the threatened California Tiger Salamander. As a result, the applicant may participate in the San Joaquin County Multi-Species Habitat Conservation Plan administered by the San Joaquin Council of Governments. Riparian Habitat As identified on the General Plan map and through site inspections by Moore Biological Consultants the project site has a creek designated as Open Space Resource Conservation Area. Development Title 9-1510.5 states: Parallel to any natural bank of a waterway, a natural open space for riparian habitat and waterway protection shall be maintained to provide nesting and foraging and the protection of waterway quality. The minimum width of said open space shall be one-hundred (100) feet, measured from the mean high water level of the natural bank or fifty (50) feet back from the existing riparian habitat, whichever is greater. Water-dependent uses may be permitted in this buffer. Loss of Farm Land According to the San Joaquin Important Farmland Map of (Department of Conservation) portions of Lots 1, 2, 3, 50, 51, 52 and 53, a total 7 (seven) acres, is classified as Farmland of Local Importance. The loss of this land, as a result of this project, is considered a cumulative significant loss of agricultural land. The County is concerned about the conversion of agricultural land and potential mitigation measures. The California Environmental Quality Act (CEQA) Guidelines provide for five categories of mitigation measures that avoid, minimize, rectify, reduce, eliminate, or compensate for significant environmental effects of the proposed project (Section 15370). Compensation as a mitigation technique is used to justify the loss of habitat for rare, threatened, or endangered species. 4
