FEMA flood zone rules in Corvallis, OR — also called floodplain regulations or special flood hazard area (SFHA) rules — determine flood insurance requirements and elevation standards for new construction.
Oregon's Statewide Planning Goal 7 and ORS 197.180 require every city and county to adopt floodplain regulations meeting or exceeding FEMA National Flood Insurance Program minimums. State building code chapters bind floodplain construction statewide.
Statewide Planning Goal 7 (Areas Subject to Natural Hazards) and ORS 197.180 obligate Oregon cities and counties to apply FEMA-mapped Special Flood Hazard Area regulations, restrict development that would raise base flood elevation, and require lowest-floor elevation or floodproofing per the Oregon Residential Specialty Code R322 and Oregon Structural Specialty Code Section 1612. The Department of Land Conservation and Development coordinates the state's NFIP participation and reviews ordinances. Failure to maintain compliant local rules risks NFIP suspension, ending federally backed flood insurance and disaster assistance for residents. Substantial improvement and substantial damage thresholds apply uniformly statewide.
Building below base flood elevation without proper elevation or floodproofing violates the state building code, can void NFIP coverage, and exposes owners to enforcement under ORS 455.895.
