Jefferson River Flood Mitigation Project

Floodwise Project 2023 Recap

“Reader’s Digest Version”

The City of Three Forks submitted funding applications to FEMA in January 2022 for the purposes of funding a flood mitigation project to reduce flood risk from the Jefferson River.  The proposed mitigation is a grass-lined conveyance channel and culvert crossing improvement project that will intercept flood waters west of town and divert them back to the Jefferson River before ever reaching the city.

The conveyance channel would be approximately 8,000 lineal feet.  Channel dimensions are anticipated to be 100-feet wide, 5-feet deep, with 3:1 side slopes. The project will include a culvert crossing structure to carry water underneath MT state highway 2 before terminating into a natural side channel of the Jefferson River.  The project cost is estimated at $5.5 million.

The City learned that FEMA has selected Three Forks for final review of a Flood Mitigation Assistance (FMA) grant at 75% of the total project cost.

We must now work on funding the remaining 25% through a Special Improvement District (SID).  The SID represents an area in which landowners would be assessed to fund improvements that benefit the district, and the maintenance thereof.  Landowners have the opportunity to protest the creation of this district during an upcoming protest period.

Public Hearings

Public hearings have been held on 9/27/2022 and 10/25/2022 to Create Special Improvement District #34 “Jefferson River Floodplain Mitigation Project & Maintenance”.  Zero written protests were received, and the Council approved the creation of this SID at its 10/25/2022 meeting.

Next Steps

We have sent the District details to the Treasurer’s office to be on the 2023 tax rolls.

We also have met with the affected landowners where the proposed channel would be located, and will work soon on the environmental and historical assessment surveys.
