The Federal Emergency Management Agency (FEMA) has issued a Flood Insurance Study (FIS) and Flood Insurance Rate Map (FIRM) for Spokane County effective July 6, 2010.
The FIS and FIRM are used to identify areas of special flood hazard, which are areas that have a 1% or greater chance of flooding any given year (previously known as the 100 year floodplain). Development within the areas of special flood hazard is regulated by Spokane Municipal Code Chapter 17E.030 Floodplain Management as required by FEMA.
