Some RestrictionsErosion Control

Grading and erosion-control plans require City approval before work begins.
Erosion and Sedimentation Control — Chapter 15.28 (Grading and Erosion Control Ordinance)
Some RestrictionsCoastal Development
Rocklin is an inland Sacramento-metro city in Placer County roughly 90 miles from the Pacific Ocean. It lies entirely outside the California Coastal Zone, so the California Coastal Act (Pub. Res. Code Div. 20, §30000 et seq.) and the Coastal Commission's coastal development permit (CDP) requirements do not apply within the city.
No Local Coastal Rule — Rocklin Is Inland, Outside the California Coastal Zone
Few RestrictionsFlood Zones
Rocklin Municipal Code Ch. 15.16 (Flood Hazard Areas) implements the National Flood Insurance Program (NFIP) for the City. Development in FEMA-designated Special Flood Hazard Areas (SFHAs, 1% annual chance floodplain) requires a Flood Zone Development Permit from the Engineering Division and must meet base flood elevation (BFE) standards.
Flood Hazard Areas — Municipal Code Chapter 15.16 and NFIP Participation
Some RestrictionsGrading & Drainage
Grading and drainage in Rocklin are controlled by Municipal Code Ch. 15.28 (Grading) together with the City's Improvement Standards and January 2019 Post-Construction Manual, which implement Low Impact Development (LID) requirements from the State Phase II MS4 Permit (WQO 2013-0001-DWQ).
