5.0 Environmental Analysis 5.1 Land Use <br />Avion Project SEIR <br />Page 5.1-3 <br />5.1.3.3 Land Development Code <br />a. Environmentally Sensitive Land Regulations <br />On January 1, 2000, Environmentally Sensitive Lands (ESL) Regulations were adopted by the San <br />Diego City Council as a part of the LDC. The purpose of the ESL Regulations is to protect and <br />preserve environmentally sensitive lands and the viability of the species supported by those lands. <br />The regulations are intended to assure that development occurs in a manner that protects the <br />overall quality of the resources and the natural and topographic character of the area. It is further <br />intended that the development regulations for ESL, which include guidelines for biology, flood <br />hazard areas, steep hillsides, and coastal bluffs and beaches, serve as standards for the <br />determination of impacts and mitigation. Within the project site, ESL development regulations apply <br />to sensitive biological resources, such as coastal sage scrub, southern mixed chaparral, and <br />wetlands, which are discussed in detail in Section 5.2 below. <br />According to the ESL regulations, development that proposes encroachment into steep hillsides is <br />subject to Municipal Code §143.0142 Development Regulations for Steep Hillsides, and the Steep <br />Hillside Guidelines in the Land Development Manual. Outside of the MHPA, the allowable <br />development area includes all portions of the premises without steep hillsides. The regulations state <br />that steep hillsides shall be preserved in their natural state, except that development is permitted in <br />steep hillsides if necessary to achieve a maximum development area of 25 percent of the premises. <br />Development encroachment into steep hillsides and sensitive biological resources within the MHPA <br />is restricted. Development within the MHPA beyond the allowed 25 percent would require a MHPA <br />boundary line adjustment. A Site Development Permit (SDP) is required for projects proposing to <br />impact any ESL. <br />b. Historical Resources Regulations <br />The purpose of the City’s Historical Resources Regulations, found in Section 143.0251 of the LDC, is <br />to protect, preserve, and, where damaged, restore the historical resources of San Diego, which <br />include historical buildings, historical structures or objects, important archaeological sites, historical <br />districts, historical landscapes, and traditional cultural properties. These regulations are intended to <br />assure that development occurs in a manner that protects the overall quality of historical resources. <br />The Historic Resources Regulations require that development affecting designated historical <br />resources or historical districts shall provide full mitigation for the impact to the resource, in <br />accordance with the Historical Resources Guidelines of the Land Development Manual, as a <br />condition of approval. If development cannot, to the maximum extent feasible, comply with the <br />development regulations for historical resources, then a project would require a permit. <br />5.1.3.4 Multiple Species Conservation Program Subarea Plan <br />The MSCP is a comprehensive, long-term habitat conservation planning program that covers <br />approximately 900 square miles in southwestern San Diego County under the federal and state <br />Endangered Species Acts and state Natural Community Conservation Planning (NCCP) Act of 1991. <br />Local jurisdictions, including the City, implement their portions of the regional umbrella MSCP <br />through subarea plans, which describe specific implementing mechanisms. The City’s MSCP Subarea
