SAN LEANDRO SHORELINE DEVELOPMENT EIR ADDENDUM PROJECT CITY OF SAN LEANDRO a significant impact. Mitigation Measure BIO -3, required for the Original Project, addressed impacts of proposed development to jurisdictional waters by requiring appropriate controls and regulatory authorizations through compensatory mitigation for wetland modifications. As with the Original Project, modifications below the Mean High Water would be subject to permit approval from the U.S. Army Corps of Engineers (ACOE) and San Francisco Bay Regional Water Quality Control Board (RWCQB). Further, water features may be considered jurisdictional wetlands or waters by the ACOE and/or California Department of Fish and Wildlife (CDFW) for the Modified Project. Authorizations from State and federal regulatory agencies may include the ACOE and RWQCB under Section 404 and 401 of the Clean Water Act, and possible CDFW under the Streambed Alteration Agreement program. The 152 single family residences and the 48 townhomes on the existing golf course for the Modified Project constitutes an additional development footprint in comparison to the Original Project and may encroach on existing wetland areas on the golf course, representing a larger impact area. Mitigation Measure BIO -3 would also be implemented for the Modified Project which would ensure that all wetlands which are potentially impacted, newly or previously identified, by the Modified Project would be identified through a jurisdictional wetland delineation verified by the Army Corps. Furthermore, compensatory mitigation through a Wetland Protection and Replacement Program would be implemented, and regulatory agencies with relevant jurisdiction would be required to give approval. With implementation of Mitigation Measure BIO -3, the Modified Project would not result in a new impact or a substantial increase in magnitude of the existing impacts to wetlands. BIO -d. As with the Original Project, the Modified Project would result in modifications to existing wildlife habitat but would not interfere with existing movement opportunities and use of native wildlife nursery areas. The project site is mostly development with minimal wildlife habitat value, with the exception of the open waters of the marina basin and San Francisco Bay, which would be improved through removal of the existing dock system and creation of enhanced natural shoreline along lower segments of the existing riprap. Existing habitat, including the monarch butterfly roosting habitat at the southeast edge of the golf course would remain unaffected with the Modified Project. Potential adverse impacts on fish and other aquatic species would be avoided through implementation of Mitigation Measures BIO -1 and BIO -3 as described in the Certified EIR. Therefore, the Modified Project would not result in a new impact or a substantial increase in magnitude of any existing impacts to wildlife movement opportunities and use of native wildlife nursery areas. BIO -e. The Modified Project would not conflict with any relevant goals and policies in the City of San Leandro General Plan related to protection of biological and wetland resources. Consistency with relevant policies would be achieved through compliance with Mitigation Measures BIO -1A, BIO -1B, BI0-1C, and BIO -3. Furthermore, implementation of Mitigation Measure BIO -5A, Tree Protection and Replacement, and Mitigation Measure BIO -5B, reaffirming implementation of Mitigation Measure BIO -1A, would address potential impacts on regulated trees. Therefore, the Modified Project would not result in a new impact or a substantial increase in magnitude of any existing impacts to any local policies or ordinances protecting biological resources, such as a tree preservation policy or ordinance.
