Some RestrictionsCoastal Development
Most development in Ventura's coastal zone — construction, grading, change of use, vegetation removal, demolition — requires a Coastal Development Permit (CDP) under SBMC Chapter 24.515 and the City's certified Local Coastal Program (LCP). The California Coastal Act (Pub. Resources Code §30000 et seq.) governs, with appeal jurisdiction retained by the California Coastal Commission for projects between the sea and the first public road, on tidelands, and in other appealable areas.
