Oakland's S-9 and S-10 hillside zoning overlays in the Oakland Hills regulate grading, geologic hazard, ridgeline visibility, tree retention, and access for fire trucks, with extra Planning approval for new homes after 1991 firestorm lessons.
Title 17 Planning Code applies special hillside regulations through overlays in the Oakland Hills above the 580 freeway. Standards address slope-stability soils reports, grading limits to reduce landslide risk, ridgeline protection, retention of significant native trees, fire-truck access turnaround minimums, and limits on cut-and-fill volumes. Projects in mapped Earthquake Fault Zones face additional Alquist-Priolo geologic study requirements. Wildfire-resilient construction (Chapter 7A of the California Building Code) applies in the Very High Fire Hazard Severity Zone, and view-protection design review is common.
Permit denial without geologic study; stop-work for unauthorized grading; restoration of slopes at owner cost; fines under building and grading codes; CEQA exposure for hillside projects with significant impacts.
