Montgomery County Precinct 4 Announces Flood Mitigation Grant Plan
Commissioner Gray and Montgomery County Precinct 4 held a public meeting last week to showcase the Montgomery County Precinct 4 Flood Mitigation Grant Plan, one of the many efforts focused on reducing flood risk and improving community resilience across Precinct 4. This effort is supported through grant funding awarded under FEMA’s Flood Mitigation Assistance (FMA) Program, administered by the Texas Water Development Board (TWDB). The FMA Program provides funding to help communities reduce or eliminate the risk of repetitive flood damage to structures insured by the National Flood Insurance Program (NFIP).
Study began in September 2024 and will conclude in December 2025 with a finalized Study Report with recommended projects & BCRs (benefit-cost ratios). Projects must show measurable benefits and cost savings to qualify for FEMA funding. BCR compares the estimated benefits of a project (i.e. reduced flood damages and avoided repair costs) to its total cost. If the BCR is greater than 1.0, the project’s benefits outweigh its costs, thus eligible for FEMA funding. If the BCR is less than 1.0, costs are higher than the expected benefits, thus not qualified for FEMA funding. This Study was completed by Cascade Civil Services, selected through the competitive Request For Qualifications process.
Project identification methodology:
- BCR greater than 1.0 (calculated using FEMA benefit-cost tool)
- Structures with repetitive flood loss within project area, identified through previous FEMA claims
- Project areas not located within a floodplain
- Precinct-identified locations that have drainage issues, determined by both staff in the field & calls/emails received from residents
This is Step 1 of Precinct 4’s Flood Mitigation Grant Plan. Based on the project identification methodology, 15 proposed locations were selected of the 43 evaluated locations that are in need of drainage improvements and also qualify for grant funding through the FMA Program. The total estimated investment would bring $53 million to Precinct 4, benefitting an estimated 440 homes.
Precinct 4 will submit one project per federal grant cycle for funding through FEMA’s Flood Mitigation Assistance (FMA) Program, anticipated yearly. Once FEMA grant funding is approved, the projects will enter final design, permitting & construction. The estimated time to complete this Flood Mitigation Grant Plan is approximately 20 years, and aligns with Precinct 4’s overall 20-Year Drainage Plan. The proposed projects identified will support the ongoing drainage improvements that Precinct 4 is continuously working on.
