Preserving Our Scenic Coastline

Along with highway and rail improvements from La Jolla to Oceanside, the North Coast Corridor Program includes $200 million to preserve, enhance and protect coastal habitats in the corridor. The program:

• Creates several hundred acres of preserved coastal habitat
• Improves the health of six coastal lagoons
• Provides new and improved ways to reach the beach

In an effort to minimize impacts and to coastal lagoons, highway and rail bridge improvement projects will be constructed concurrently. As aging rail and highway bridges are replaced with modern structures, the new designs will feature longer spans with fewer piers in the water. The smaller footprint of these bridges will help to improve tidal flow in many of the lagoons, resulting in healthier coastal environments.

To prioritize these environmental enhancements, Caltrans and SANDAG have developed the Resource Enhancement Mitigation Program, which outlines opportunities to restore and enhance lagoon ecosystems. In the years ahead, the two agencies will work with community and environmental stakeholders to determine how to prioritize the environmental improvements. Funding will be used from the existing TransNet Environmental Mitigation Program for regional transportation improvements, which is administered by SANDAG.
