Floodplain Development Overview

The two most commonly used forms for floodplain development are the Floodplain Development Permit and the Elevation Certificate. The Nez Perce County Flood Damage Reduction Ordinance #43 requires that a development permit be obtained prior to construction or development begins within any area of special flood hazard, also known as the 100-year floodplain or “A Zone” on the FEMA Flood Insurance Rate Map (FIRM). The permit is required for all structures and for all development (i.e. dredging, drilling, excavation, filling, grading, mining, paving, etc.) within any area of special flood hazard.

If you are building or renovating a residence in an A Zone, you may also be required to complete an Elevation Certificate prior to obtaining a building permit. In addition, lenders often require Elevation Certificates for A Zone properties even if it is not required by Nez Perce County.

If you have questions regarding floodplain issues, please call or email Alison Tompkins. For additional floodplain information, go to the Flood Program Information page.
