Tumwater Floodplain

The floodplain in Tumwater is regulated through the floodplain overlay chapter of the zoning code (TMC 18.38), the building code, as well as portions of critical areas and shoreline regulations. The existing floodplain maps can be seen on the Official FEMA Flood Insurance Rate Maps for Tumwater as well as on the City of Tumwater zoning map.

FEMA is currently nearing the end of the process for updating the floodplain map for portions of the city including the Deschutes River valley. The city will be required to adopt the new floodplain maps and study in the next few months.
