Safety Improvement Project

The California Department of Transportation (Caltrans) proposes to restore the existing shoulders to continuous shoulders in each direction, improve the existing non-standard super elevation along the horizontal curve at the San Juan Fire Station, and improve existing drainage systems to collect off-site runoff along State Route 74 (SR 74) within and adjacent to Ronald W. Caspers Wilderness Park and the Cleveland National Forest in the County of Orange. The purpose of the proposed project is to reduce the number and seerity of collisions.

Information in the Initial Study/Environmental Assessment (IS/EA) describes why the project is being proposed, the range of Build Alternatives being considered, the environmental impact evaluation, and proposed avoidance, minimization and/or mitigation of potential impacts associated with the proposed Build Alternatives.
