basins and trails shall be allowed within the setback area . The trails shall be set back as far as possible from Arroyo del Valle to minimize disturbance by people and maximize habitat values. Construction project fencing shall be placed at the outer edge of the setback area. The fencing shall be maintained until all construction activities are completed. The setback requirements for trails shall also apply to other riparian corridors within the Specific Plan Area . 4. When grading of an area of one acre or greater is to occur, or when one or more trees with a trunk diameter of six inches or greater are proposed to be removed during the raptor-nesting season (February 1 to August 31), a focused survey for raptor nests shall be conducted by a qualified biologist during the nesting season. The survey shall be conducted no less than 14 days and no more than 30 days prior to the beginning of grading or tree removal. If nesting raptors are found during the focused survey , no grading or tree removal shall occur within 500 feet of an active nest until the young have fledged (as determined by a qualified biologist), or until the project applicant receives written authorization from CDFG to proceed . If the removal of nest trees is unavoidable , they shall be removed during the non-breeding season. 5. All future bridges over creeks shall be designed to preserve wildlife corridors between the greater Plan Area and the Arroyo del Valle. D. HERITAGE TREES 1. Existing trees exceeding six inches in trunk diameter as measured four feet above ground level shall be preserved whenever possible. (Exceptions for orchard trees and other non-heritage trees which do not line Vineyard Avenue and are located in Vineyard districts shall be subject to approval on a case-by-case basis by the Planning Commission. 2. A tree plan shall be submitted to the City in conjunction with all PUD development plan applications. The plan shall note all trees to be removed or disturbed that are six inches or greater in diameter and specify the precise location of the trunk and dripline , size, health, and species of all trees, with special notation of "heritage trees" as defined by the City's Heritage Tree Ordinance. 3. The tree plan shall address protection measures during grading and construction , address replacement of trees which must be removed , and review the possibility of relocating existing trees elsewhere on site . The plan shall include detailed measures to protect trees , including protective fencing approximately five feet outside of the leaf canopy edge of a tree or grove wherever grading or construction occurs within 50 feet of a tree , restrictions on irrigation within 88
