Effects to covered species (i.e., the exchanges maintains or increases the conservation of <br />covered species <br />3. Effects on habitat linkages and function of preserve areas (i.e., the exchange results in <br />similar or improved management efficiency and/or protection for biological resources); <br />4. Effects on preserve configuration and management (i.e., the exchange results in similar or <br />improved management efficiency and/or protection for biological resources); <br />5. Effects on ecotones or other conditions affecting species diversity (i.e., the exchange <br />maintains topographic or structural diversity and habitat interfaces of the preserve); and/or <br />6. Effects to species of concern not on the covered species list (i.e., the exchange does not <br />significantly increase the likelihood that an uncovered species will meet the criteria for <br />listing under either the federal or state Endangered Species Acts; City of San Diego 1998). <br />b. Land Use Adjacency Guidelines <br />The City’s MSCP Subarea Plan provides Land Use Adjacency Guidelines to avoid or reduce significant <br />indirect impacts to MHPAs from adjacent land uses. The Land Use Adjacency Guidelines include <br />drainage, lighting, noise, and slope grading recommendations for adjacent development, as well as <br />recommendations for avoiding or redirecting toxic chemicals (e.g., from landscape or agricultural <br />fertilization) and prohibition of the planting of invasive species. <br />Section 1.4.3 of San Diego MSCP Subarea Plan presents Land Use Adjacency Guidelines, as <br />summarized below. Section 1.5.2 of the MSCP provides general management recommendations to <br />implement these guidelines, as summarized below. <br />Drainage. All new and proposed parking lots and developed areas in and adjacent to the MHPA <br />must not drain directly into the MHPA. All developed and paved areas must prevent the release of <br />toxins, chemicals, petroleum products, exotic plant materials, and other elements that might <br />degrade or harm the natural environment or ecosystem processes within the MHPA. <br />Toxics. Land uses such as recreation and agriculture that use chemicals or generate by-products <br />that are potentially toxic or impactive to wildlife, sensitive species, habitat, or water quality, need to <br />incorporate measures to reduce impacts caused by the application and/or drainage of such <br />materials into the MHPA. <br />Lighting. Lighting of all developed areas adjacent to the MHPA should be directed away from the <br />MHPA. Where necessary, development should provide adequate shielding with non-invasive plant <br />materials (preferably native), berming, and/or other methods to protect the MHPA and sensitive <br />species from night lighting. <br />Noise. Uses in or adjacent to the MHPA should be designed to minimize noise impacts. Excessively <br />noisy uses or activities adjacent to breeding areas must incorporate noise reduction measures and <br />be curtailed during the breeding season of sensitive species.
