OLYMPIA – Beginning this next week through July, field surveyors contracted by the Federal Emergency Management Agency (FEMA) will collect flood data from streams connecting to the Nisqually River, including a large region in the eastern side of the County, to update flood risk maps.
This flood study will provide FEMA with important data that will help update flood maps and give Thurston County property owners information on flood risk. The information can help property owners within potential floodways determine priorities for flood insurance. The only information collected during this study will be data related to flood risk.
FEMA is requesting property owners help by providing safe and proper access to survey crews. Surveyors will work during daylight hours all days of the week, staying mostly on public land and rights-of-way. If the surveyors need brief access to privately owned properties with stream channels, bridges, culverts and dams, FEMA will contact property owners in advance for permission.
FEMA flood risk mapping provides vital information for determining fair flood insurance rates. The County’s flood planning and risk reduction efforts, and participation in FEMA’s flood insurance program, allows property owners in unincorporated areas of the County to receive discounts on their insurance rates.
