Zones starting with A or V are high-risk Special Flood Hazard Areas where federally backed mortgages require NFIP flood insurance. Zone X indicates moderate-to-minimal risk, where insurance is optional but often recommended. Your specific zone determines insurance cost, build elevation, and permit requirements in Shasta County, CA.

Summary

Any construction inside Shasta County's Restrictive Flood (F-2) District has to be anchored against flotation, collapse, and lateral movement, and Code Section 17.70.050 sets a hard elevation floor: the lowest floor of every residential structure, including the basement, must sit at least one foot above the base flood level shown on the county's FEMA-adopted flood maps.

City-specific rules exist: Redding has its own flood zones rules that differ from Shasta County's county-level regulations. If you live in Redding, check the city-specific page instead.

Notwithstanding the provisions of Sections 17.70.020, 17.70.030 and 17.70.040, all uses are subject to the following conditions and restrictions: A. Every structure shall be designed and anchored to prevent flotation, collapse or lateral movement of the structure, or portions of it, due to flooding. ... D. The lowest floor, including the basement, of all residential structures or substantial improvements to existing residential structures shall be constructed at least one foot above the base flood level.

Full Breakdown

010 states that where the two sets of rules conflict, the more restrictive one controls. 030(D). 040 requires every building permit application in the district to show elevations relative to mean sea level for the lowest floor of residential structures, or the floodproofed elevation for nonresidential ones, and the building official must find the design minimizes flood damage and manages drainage before issuing the permit. 050(E). 050(K). 050(I) and (L).

Violations & Fines

Section 17.70.060 calls variances from the elevation or floodproofing standards rare, and grants them only for unique site conditions, not hardship tied to the structure or its owner. A recorded variance must carry written notice that flood insurance premiums can run as high as twenty-five dollars per one hundred dollars of coverage, and that notice is recorded in the property's chain of title. A variance lapses if the work is not started within one hundred eighty days.

Frequently Asked Questions

How high above flood level must a new home be built in Shasta County's flood district?

Section 17.70.050(D) requires the lowest floor, including any basement, of a residential structure or substantial improvement to sit at least one foot above the base flood level shown on the county's adopted FEMA flood maps.

Can a commercial building be built below the base flood level?

Only if it is floodproofed. Section 17.70.050(E) allows a nonresidential structure's lowest floor to sit below base flood level if a registered civil engineer or licensed architect certifies the floodproofing can withstand flood depths, pressures, and forces up to one foot above that level.

Are variances from the flood elevation rule easy to get?

No. Section 17.70.060 calls variances rare and limits them to unique site conditions, not to hardships tied to the structure, its occupants, or the owner, given the health, safety, and insurance costs of building below flood level.

Where can I see if my parcel is inside the F-2 flood district?

Section 17.02.030(D) incorporates the county's FEMA flood insurance study and rate maps by reference, and keeps them on file at the Shasta County Department of Public Works and the Resource Management Department's planning division at 1855 Placer Street in Redding.
