FEMA Flood Zone Lookup

FEMA assigns every parcel in the U.S. a flood-hazard designation on its Flood Insurance Rate Maps (FIRMs). 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 Stafford County, VA.

Zone	What it means	NFIP required?
A	High-risk flood area; 1% annual chance flood, no detailed analysis.	Yes
AE	High-risk; same as A but with established Base Flood Elevations.	Yes
AH	High-risk shallow flooding (1-3 ft), usually ponding.	Yes
AO	High-risk shallow flooding (1-3 ft) with sheet flow on sloping terrain.	Yes
V	High-risk coastal zone subject to wave action (no BFE).	Yes
VE	High-risk coastal zone with wave action and established BFEs.	Yes
X (shaded)	Moderate risk; between the 1% and 0.2% annual chance flood.	Recommended
X	Minimal risk; outside the 0.2% annual chance floodplain.	No

Summary

Stafford County's Flood Hazard Overlay District bars new fill, construction or other development within a mapped floodway unless an engineer proves it will not raise flood levels during the base flood. The rule applies to every parcel FEMA maps as a special flood hazard area, county-wide.

These county ordinances apply to unincorporated areas of Stafford County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

(c)Applicability. These provisions shall apply to all privately and publicly owned lands within the jurisdiction of the county and identified as areas of special flood hazard identified by the county or shown on the flood insurance rate map (FIRM) or included in the flood insurance study (FIS) that are provided to the county by FEMA. ... (1)The floodway district is in an AE Zone and is delineated, for purposes of this section, using the criterion that certain areas within the floodplain must be capable of carrying the waters of the one (1) percent annual chance flood without increasing the water surface elevation of that flood by more than one (1) foot at any point. ... a.Within any floodway area, no encroachments, including fill, new construction, substantial improvements, or other development shall be permitted unless it has been demonstrated through hydrologic and hydraulic analysis, performed in accordance with standard engineering practice, that the proposed encroachment will not result in any increase in flood levels within the county during the occurrence of the base flood discharge.

Full Breakdown

Stafford County Code § 28-57 creates the Flood Hazard (FH) Overlay District, layered over the county's regular zoning districts wherever FEMA's flood insurance rate map shows a special flood hazard area. Under subsection (c), these provisions apply to every privately and publicly owned parcel identified on the FIRM or the flood insurance study prepared for the county. prohibits any encroachment, including fill, new construction, substantial improvements, or other development, within a designated floodway unless a hydrologic and hydraulic analysis by a qualified professional engineer demonstrates the work will cause no increase in flood levels during the base flood discharge.

If that showing can't be made, the applicant's only path is a Conditional Letter of Map Revision endorsed by the county and approved by FEMA before construction. Manufactured homes are barred from any floodway location outright, except for replacements inside an existing manufactured home park that meet anchoring, elevation and encroachment standards. Every use, activity or development in a floodplain district, including placing a manufactured home, needs a zoning permit before work starts, and the floodplain administrator must review each application to confirm the site is reasonably safe from flooding before that permit issues.

The board of zoning appeals hears variance requests, but subsection (x) forbids granting any variance within a floodway district that would increase the 100-year flood elevation, regardless of hardship.

Violations & Fines

Filling, building or otherwise developing in a mapped floodway without the required hydrologic and hydraulic analysis, or without the zoning permit Stafford County Code § 28-57(s)(1)a requires for any floodplain activity, is enforced as a zoning violation under § 28-311. Flood insurance can be withheld from noncompliant structures, and the floodplain administrator can pursue civil penalties up to $100 per day, capped at $3,000, under § 28-314(c).

Frequently Asked Questions

Can I build in a mapped floodway in Stafford County?

Only if a professional engineer's hydrologic and hydraulic analysis shows the project will not raise flood levels during the base flood, per Stafford County Code § 28-57(q)(1)a. Without that showing, the applicant must obtain a Conditional Letter of Map Revision from FEMA, with the county's endorsement, before any fill or construction can proceed.

Do I need a permit for floodplain development?

Yes. Section 28-57(s)(1)a requires a zoning permit for any use, activity or development in a floodplain district, including placing a manufactured home. The floodplain administrator reviews the application to confirm the site is reasonably safe from flooding before issuing the permit.

Can the Board of Zoning Appeals waive floodway rules?

Not when it comes to flood height. Section 28-57(x) bars the board from granting a variance for any proposed use, development or activity within a floodway district that would increase the 100-year flood elevation, no matter what hardship is claimed.
