Flood Zones: Lincoln vs Rocklin

How do I know if my Lincoln property is in a flood zone?

Check FEMA's Flood Map Service Center (msc.fema.gov) using your address, or submit a Flood Determination Request to the City via the Lincoln Flood Zone Information page. The City participates in NFIP, so federally backed mortgages on properties in Zone A or AE require flood insurance.

Can I build a new home in a Lincoln floodplain?

Yes, but Chapter 15.32 requires a floodplain development permit and the lowest floor must be elevated to or above the Base Flood Elevation shown on the effective FIRM. Non-residential structures may instead be dry-floodproofed. Variances are available only in extremely limited circumstances under §15.32.280.

How do I find out if my Rocklin property is in a flood zone?

Use the FEMA Flood Map Service Center (msc.fema.gov) or submit a Flood Zone Designation Request to Rocklin's Engineering Division. The City uses FEMA's effective FIRMs.

Do I need a special permit to build near a Rocklin creek?

If the parcel touches a FEMA-mapped Special Flood Hazard Area, you need a Flood Zone Development Permit under MC Ch. 15.16 in addition to standard building permits, and new habitable floors must be at or above the Base Flood Elevation.
