The Board of Supervisors finds that the ecosystems of the County and the vegetation communities and sensitive species they support are fragile, irreplaceable resources that are vital to the general welfare of all residents; these vegetation communities contain habitat value which contributes to the region's environmental resources; special protections for these vegetation communities must be established to prevent future endangerment of the plant and animal species that are dependent upon them. This Chapter will protect the County's biological resources and prevent their degradation and loss by guiding development outside of biological resource core areas, and by establishing mitigation standards which will be applied to discretionary projects. Adoption and implementation of this Chapter will enable the County of San Diego to achieve the conservation goals set forth in the Subarea Plan for the Multiple Species Conservation Plan ("MSCP"), adopted by the Board of Supervisors on October 22, 1997, and will preserve the ability of affected property owners to make reasonable use of their land subject to the requirements of the California Environmental Quality Act (CEQA), Public Resources Code Section 21000 and following, and other applicable laws, and the avoidance and mitigation requirements contained herein.
This Chapter sets forth the criteria for avoiding impacts to Biological Resource Core Areas and to plant and animal populations within those areas, and the mitigation requirements for all projects requiring a discretionary permit. It is the policy of this Chapter to promote the preservation of biological resources by directing preservation toward land which can be combined into contiguous areas of habitat or linkages. It is further the policy of this Chapter to give greater value to the preservation of large contiguous Biological Resource Core Area or to linkages when formulating avoidance and mitigation requirements.
The Chapter consists of two parts. The first part explains how mitigation for impacts is determined. The habitat and vegetation community must first be identified at the impact site and at the area proposed for mitigation. This section directs mitigation to areas that will lead to ultimate assembly of a regional preserve system consisting of core habitat areas and the linkage that connect them.
The second part of the Chapter sets out specific mitigation requirements for impacts to certain species. These species specific mitigation requirements are necessary because San Diego County has a high number of sensitive plants and animal species occurring within and without the preserved areas. Protecting these sensitive species is required in order to gain coverage of the species under the MSCP plan. Depending on the sensitivity of the individual species, their avoidance or mitigation is also necessary in order to comply with the California Environmental Quality Act. The two parts work together and are to be applied at the same time.
Nothing in this Chapter shall be construed to reduce any requirements to protect environmentally sensitive lands contained in any other County plan, ordinance, policy or regulation or the California Environmental Quality Act (CEQA), Public Resources Code section 21000 and following and the State CEQA Guidelines, 14 Ca. Code Regs. Section 15000, and following.
