Should city officials require strict safety remediation for slope failures in local neighborhoods?
A San Diego hearing officer has approved a project to restore a slope in La Jolla that failed following a pool plumbing issue in 2023. The work addresses erosion concerns on a six-acre open-space lot located between Caminito Bassano East and Hillside Drive.
Why it matters
The restoration is critical for stabilizing terrain in an environmentally sensitive, very high fire severity zone where erosion risks are elevated. It follows years of community review to ensure the repair prevents future slope failure and runoff impacts on nearby homes.
The approved project covers a 0.03-acre area of slope failure. Work requires installing 12-foot-long geogrid fabric at 24-inch vertical intervals within soil compacted to a 90 percent density standard.
The players
Patricia Bautista
A San Diego hearing officer responsible for reviewing and authorizing local land-use and development projects.
La Jolla Community Planning Association
A local advisory group that provides community feedback on neighborhood development and planning initiatives.
The details
To remediate the site, crews will excavate below the surface of the existing failure point. They will reinforce the earth by horizontally installing 12-foot-long geogrid fabric at 24-inch vertical intervals between soil layers. This layering process, combined with compaction to 90 percent density, is designed to restore the slope to its pre-failure condition while mitigating future erosion and runoff risks for adjacent properties.
Timeline
October 2023: Slope failure occurred due to an improperly sealed pool autofill valve.
Feb. 5, 2025: An application for development permits was formally filed.
May 2025: The La Jolla Development Permit Review committee recommended approval.
June 2025: The La Jolla Community Planning Association ratified the project.
Oct. 12, 2026: A city hearing officer approved the restoration project.
The Home Front
This project highlights the rigorous permitting requirements for properties located within environmentally sensitive zones in San Diego. It follows established municipal standards for land remediation after property-related damages impact public open space.
Homeowners with pools or irrigation systems on or near slopes should regularly inspect autofill valves to prevent water-induced soil failure. If you own property in a designated fire severity zone, consult a licensed professional to assess your site for erosion or drainage vulnerabilities.
The takeaway
Slope failure can often be traced back to minor plumbing issues, emphasizing the importance of routine maintenance for exterior water systems. Check your property's exterior plumbing lines and pool autofill valves annually to ensure they are sealed properly.
