Mount Helix Drive Rock Wall Maintenance


Mount Helix Drive Rock Wall (Wall) is located on Mount Helix Drive, in the unincorporated community of Valle de Oro in San Diego County (County). Mount Helix Drive includes a lower loop and an upper loop, with historic rock walls on both sides of the traveled way. Approximately 1.5 mile long, the walls were originally built in the early 1930s. In 1989 the Board of Supervisors rezoned Mount Helix Drive as a Historic Landmark to protect the historic integrity of the Wall. Furthermore, Valle De Oro’s Community Plan states that the design of the road improvements should maximize “environmental and aesthetic considerations consistent with safety needs.”


The San Diego County Department of Public Works performs regular maintenance and repairs on the historic rock walls along Mt Helix Drive. We are in the preliminary stages of developing an updated plan for the rock walls that will reassess our current maintenance and repair efforts. It will also allow us to explore possible solutions to maintain portions of the wall that may need more substantial attention.

Upcoming Activities: 

The Long Term Maintenance Plan (LTMP) draft is currently under comment and review. The final draft LTMP is anticipated to be finalized early 2024.
