San Diego dismisses stormwater appeal on La Jolla development, tightens drainage conditions
City of San Diego Public Utilities Department, California · Meeting date: May 19, 2026 · Published: May 26, 2026
The City Council rejected an appeal centered on stormwater discharge volumes and sewer easement rights for a six-lot subdivision, advancing the project with newly added engineering and public utility conditions.
Key points
- Appellants argued the project's proposed 6.7 cubic feet per second stormwater discharge could overwhelm downstream infrastructure.
- Neighbors contested the developer's right to install private sewer and drainage lines in a private roadway without co-owner consent.
- City staff determined that private sewer laterals and stormwater facilities connecting to public systems qualify as permitted "public utilities" under a 1949 easement.
- The council approved the project 7-0 after adding new permit conditions to address hydraulic sizing, biofiltration, and Q100 flood mitigation.
Full report
The San Diego City Council voted 7-0 on May 19, 2026, to deny an appeal against a residential subdivision at 8303 La Jolla Shores Drive. The appeal, brought by downstream neighbors, focused heavily on the adequacy of the project’s stormwater drainage design and the legal right to install sewer and stormwater infrastructure within a shared private roadway.
The appellant raised alarms over the project's plan to discharge approximately 6.7 cubic feet per second of stormwater—equivalent to roughly 3,000 gallons per minute—into Calle Frescota and La Jolla Shores Drive. Anna Ludke, an attorney representing the appellant, cited findings from a third-party water resources engineer who identified multiple alleged deficiencies in the developer's stormwater management plan.
Specific engineering concerns included a brow ditch along the western boundary that bypassed a mitigation basin, potentially undermining water quality treatment and Q100 (100-year flood) mitigation. The appellant also pointed to an undersized biofiltration basin, inadequate freeboard for Q100 ponding, and the omission of hydraulic sizing and inlet capture analysis for a proposed 12-inch PVC storm drain.
Beyond engineering, the appeal challenged the developer's authority to install private drainage and sewer facilities in Calle Frescota. City project manager Veronica Davison clarified the city's regulatory stance: an original 1949 grant deed allows for the "installation, repair, and replacement of public utilities" within the right-of-way. Davison noted that private sewer laterals and stormwater infrastructure connecting to public utility systems constitute allowable uses under this easement, which is customary practice.
Applicant architect Brian Will and civil engineer Daniel Valdez defended the design, noting the site utilizes biobasins to capture east-to-west drainage before routing excess flows to a public curb outlet.
Ultimately, Council President LaCava moved to deny the appeal, but only after city staff introduced strict modifications to the project's permits. The council approved the project with a revised engineering condition addressing the drainage study, two new public utilities conditions for sewer facilities, and a tentative map condition ensuring drainage and sewer improvements comply with state civil code requirements.
