TABLE 1-1 SUMMARY OF IMPACTS AND MITIGATION MEASURES <br />Significant Impact <br />Significance <br />Before <br />Mitigation Mitigation Measures <br />Significance <br />With <br />Mitigation <br />The MBRHPP shall be submitted as part of the Site Plan Review <br />and/or tentative map application, whichever is first, and shall include <br />the following components: <br /> The MBRHPP shall be prepared by a qualified biologist <br />experienced in management of monarch butterfly colonies in <br />California, and shall describe existing winter roosting colony <br />habitat essential to the monarch butterfly colony and required <br />measures taken to ensure both roosting and wind buffering trees <br />are adequately protected. <br /> All mature blue gum eucalyptus and pine trees in the colony and <br />along the east edge of the South Golf Course Residential <br />development shall be preserved and protected as part of the <br />MBRHPP, with trunk locations and edge of canopy clearly mapped <br />by engineered survey in relation to proposed building footprints, <br />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 <br />edge of the proposed South Golf Course residential area may <br />require relocation as part of the MBRHPP to provide a larger <br />setback if there is a risk to these trees as a result of construction <br />activities or future maintenance for fire fuel management, <br />landscape maintenance, and other practices. Where private yards <br />and/or common open space associated with the South Golf <br />Course residential area extends under the canopy of the buffering <br />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 <br />construction, tree removal, and vegetation management within <br />200 feet of the edge of trees known to support the winter <br />roosting colony, including tree removal, pruning, and herbicide <br />application, and appropriate timing of construction and required <br />management within this zone. Grading and equipment operation, <br />any tree removal, pruning, or herbicide application in the vicinity <br />shall be restricted from August 1 through March 31 to prevent <br />any inadvertent disturbance to the winter roosting colony.
