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 Salem, OR.

Full Breakdown

030(c). 100 is required. Class 1 applications must include a completed application, site plans showing existing and proposed structures and drainage, the proposed lowest-floor elevation for riverine zones, floodproofing elevation for non-residential structures, a description of any watercourse alteration, Base Flood Elevation data when required, a substantial-improvement calculation, and the amount and location of any fill or excavation. Class 2 applications add a floodplain mitigation assessment and mitigation plan showing no net loss of floodplain storage, water quality, and riparian vegetation. 045(i)(4). The Director may suspend or revoke a permit issued in error, issued on incorrect or misleading information, or where work departs from the approved plans, with appeal to the Hearings Officer under SRC chapter 20J.

Violations & Fines

Building or developing in the SFHA without full compliance with SRC Chapter 601 is an infraction under SRC 601.055(b), and the City may pursue any other lawful remedy to stop or correct the work. The Director can suspend or revoke a floodplain development permit obtained through incorrect information or violated in the field; a permit holder who fails to maintain the completed work as required can be served a correction notice, and unaddressed maintenance costs become a lien against the property under SRC 601.065.

Frequently Asked Questions

Do I need a permit to build in Salem's floodplain?

Yes. SRC 601.045(a) requires a floodplain development permit before any construction or development begins within the Special Flood Hazard Area established under SRC 601.030(a), or within an interim flood hazard area the Director designates under SRC 601.030(c). The requirement covers all structures, including manufactured dwellings, plus fill and other development activity, not just buildings.

What's the difference between a Class 1 and Class 2 floodplain permit?

A Class 1 permit is for development in the SFHA that does not need a mitigation assessment and is processed as a Type I procedure under SRC Chapter 300. A Class 2 permit is required when a mitigation assessment under SRC 601.100 applies, and it is processed as the more involved Type II procedure instead.

What happens if I start work before getting the permit?

SRC 601.045(i)(4) doubles the plan review and permit fee when work begins or proceeds before the permit is obtained. Paying the doubled fee does not excuse the applicant from otherwise complying with the chapter, and the Director can still pursue suspension, correction orders, or other lawful enforcement for the underlying violation.
