Finding Changes or alterations have been required in, or incorporated into, the project which mitigate or avoid the significant effects on the environment. Facts in Support of Finding The City of Pleasanton has adopted the following measures which will reduce potential impacts to oak woodland/savanna habitat a less-than-significant level: Mitigation Measure 4.3-1a: An Oak Woodland Restoration and Management Plan shall be prepared by a qualified biologist and submitted to the City prior to the issuance of a Grading Permit. This Plan shall include provisions to: • Maximize the diversity of plants and animals native to oak woodlands of the region; • Encourage natural regeneration of native oaks (including blue oaks, valley oaks and coast live oaks)within undeveloped portions of the project site; • Reduce fire hazards during the dry season; and • Restrict livestock grazing. The oak woodland management plan would address tree replacement requirements as stipulated through City consultation with the CDFW for the project. Presently, the CDFW generally specifies a replacement ratio of 3:1 for the replacement of native oaks, regardless of the lost trees' positions relative to the riparian zone. The management plan should include restrictions on livestock grazing to ensure natural regeneration of oaks within the open space areas. Mitigation Measure 4.3-1b: The relevant provisions of the City of Pleasanton's Tree Ordinance, including acquisition of a tree removal permit (Section 17.16.020), reporting requirements for new property development (Section 17.16.050) and protection of existing trees (Section 17.16.070) shall be implemented. The Oak Woodland Restoration and Management Plan discussed above shall indicate the ratio, location, species, source of plant material and timing for planting. It shall also describe plans for maintenance and irrigation. Heritage trees should be replaced at a ratio consistent with the City's tree ordinance with small nursery stock. These ratios shall compensate for habitat values lost from the removal of mature trees. Planting time between November and January is recommended. To preserve the genetic integrity of trees of the site, acorns and seeds to be propagated should be collected on-site. A minimum maintenance and irrigation time of three years is recommended. In order to optimize tree preservation on-site, the following measures formulated by Hort Science shall be implemented to protect trees that are proposed to be retained: Design Recommendations 1. Verity the location and tag numbers of all trees within 25 feet of the proposed construction areas 2. Allow the Consulting Arborist to review all future project submittals including grading, utility, drainage, irrigation, and landscape plans. 3. Prepare a site work plan which identifies access and haul routes, construction trailer and storage areas, etc. LUND RANCH II(PUD-25)RESIDENTIAL PROJECT 5 FINDINGS
