Folsom has about 23 miles of natural creeks/channels with associated floodplains. The city participates in the National Flood Insurance Program (NFIP), a federal government program that subsidizes the amount that property owners pay for flood insurance. A critical component of the NFIP is the identification and mapping of the city’s floodplains to create awareness of flood hazards and to provide the data necessary for floodplain management activities.
Floodplain maps, also known as Flood Insurance Rate Maps (FIRMs) support the flood insurance program that enables homeowners, renters, and business owners to reduce their financial risk. A FIRM is a joint local-federal floodplain management tool issued by the Federal Emergency Management Agency (FEMA).
FIRMs are available for viewing at Folsom City Hall in the Community Development Department, 50 Natoma Street. To learn more about flood risk, flood insurance, and discover ways to reduce risk, visit FEMA’s Floodsmart website.
Within the City of Folsom there are four primary watersheds; Willow Creek, Humbug Creek, Alder Creek and Hinkle Creek watersheds. Currently, there are FIRMs for the Hinkle Creek watershed and a portion of the Willow and Humbug Creek watershed. Currently, no FIRM has been issued by FEMA for the Alder Creek watershed.
In 2014, the city obtained grant funding from FEMA to update and complete FIRMs for the Humbug and Willow Creek watersheds. The preliminary maps are expected to be complete in 2016. In 2015 the City obtained additional grant funding to update the FIRMs for the Hinkle Creek watershed and develop new FIRMs for the Alder Creek watershed. That project began in November 2015.
