The South Bay Expressway Biological Mitigation Program as a Functional and Progressive Design in Relation to the San Diego Regional Ecological and Regulatory Landscape

California Department of Transportation and the Federal Highways Administration (Caltrans/FHWA) take an active role in conservation planning in the county of San Diego through the design and implementation of their transportation projects. Caltrans/FHWA worked in close coordination with both public agencies and private entities to develop a biological mitigation program for the creation of the new alignment, 8-lane highway of State Route 125 (SR 125), in a way that is consistent with and would enhance the region’s conservation programs. In a broad-based coordination between multiple agencies, the private sector, and environmental groups, regional stakeholders have developed the Multiple Species Conservation Program (MSCP) as a mechanism to preserve large tracts of high value natural habitat while providing for economic growth. In keeping with the MSCP’s unilateral coordination of both public and private partnerships, Caltrans/FHWA has worked to develop mitigation efforts for their transportation projects that address regional conservation endeavors. This paper focuses on Caltrans/FHWA’s biological mitigation program for the construction of SR 125, illustrating how mitigating for transportation-based biological impacts can (1) fulfill the fundamental goals of habitat conservation plans and (2) facilitate a close level of cooperation between stakeholder groups.
