What changes the answer in Walnut Creek.

Hillside Planned Development overlay across the Northgate corridor adds slope-band density, ridgeline protection, and story-pole noticing. Grading thresholds and Low Impact Development (LID) stormwater requirements apply per City of Walnut Creek Community Development Department — Building Division; sloped parcels require geotech and an erosion-control plan. Site access in Walnut Creek can require temporary street-use or encroachment permits depending on street width, on-street parking restrictions, and proximity to schools or transit corridors.
