Work to stabilize the coastal bluffs through Del Mar is moving forward, following a vote Monday by the Del Mar City Council. Council members approved an encroachment permit Monday night, allowing SANDAG to work on a 1.6 mile stretch of coastline. This is Phase 4 of SANDAG’s bluff stabilization project, which began 18-years ago. Work has already been completed along the bluffs at the end of 11th Street. The circles seen in the dirt to the west of the train tracks are actually the tops of 65-foot tall pilings that stabilize the bluffs.
