SAN LEANDRO SHORELINE DEVELOPMENT DRAFT EIR <br />CITY OF SAN LEANDRO <br />BIOLOGICAL RESOURCES <br />Mitigation Measure BI0-1A: Ensure Protection of Monarch Butterfly Colony. Proposed development <br />shall be designed to avoid adverse impacts on monarch butterfly winter roosting habitat, including <br />controls on removal and pruning of trees in the southeastern portion of the Project site where the <br />monarch butterfly overwintering colony is located. A Monarch Butterfly Roosting Habitat Protection <br />Program (MBRHPP) shall be prepared by a qualified biologist and ensure adequate avoidance and <br />protection of the winter roosting colony, consistent with the intent of Section 4-1-1000, Interference <br />with Monarch Butterflies Prohibited, of the San Leandro Municipal Code. The MBRHPP shall be <br />submitted as part of the Site Plan Review and/or tentative map application, whichever is first, and <br />shall include the following components: <br />■ The MBRHPP shall be prepared by a qualified biologist experienced in management of monarch <br />butterfly colonies in California, and shall describe existing winter roosting colony habitat essential <br />to the monarch butterfly colony and required measures taken to ensure both roosting and wind <br />buffering trees are adequately protected. <br />■ All mature blue gum eucalyptus and pine trees in the colony and along the east edge of the South <br />Golf Course Residential development shall be preserved and protected as part of the MBRHPP, <br />with trunk locations and edge of canopy clearly mapped by engineered survey in relation to <br />proposed building footprints, landscaping and other improvements that may otherwise disrupt <br />their function in buffeting winds. <br />■ As necessary to protect the wind buffering trees, the eastern edge of the proposed South Golf <br />Course residential area may require relocation as part of the MBRHPP to provide a larger setback <br />if there is a risk to these trees as a result of construction activities or future maintenance for fire <br />fuel management, landscape maintenance, and other practices. Where private yards and/or <br />common open space associated with the South Golf Course residential area extends under the <br />canopy of the buffering trees, appropriate CCRs shall be developed to ensure long-term <br />protection as part of future maintenance activities. <br />The MBRHPP shall identify restrictions and seasonal controls on construction, tree removal, and <br />vegetation management within 200 feet of the edge of trees known to support the winter <br />roosting colony, including tree removal, pruning, and herbicide application, and appropriate <br />timing of construction and required management within this zone. Grading and equipment <br />operation, any tree removal, pruning, or herbicide application in the vicinity shall be restricted <br />from August 1 through March 31 to prevent any inadvertent disturbance to the winter roosting <br />colony. <br />■ The MBRHPP shall be submitted for review and approval as part of the Site Plan Review and/or <br />tentative map application for the South Golf Course Residential development. <br />Significance After Mitigation: Less than significant. <br />Special -Status Fish Species <br />The Project would include improvements to areas of tidally influenced open water, and could have direct <br />and indirect effects on a number of special -status fish species, such as Central California Coastal <br />steelhead, green sturgeon, Delta smelt, Sacramento splittail, Central Valley spring -run Chinook salmon, <br />and longfin smelt, if present in the area during the time of construction. Project -related improvements <br />that could affect open water habitat of the bay include modifications to the existing riprap shoreline, <br />4.3-14 DECEMBER 2014 <br />
