Flood Management Grants

The Idaho Water Resource Board Flood Management Grant is administered by the Idaho Department of Water Resources to provide financial assistance for projects that address flood damage and reduce flood risks throughout the state of Idaho. The program is designed to support public entities responsible for managing water systems and infrastructure, particularly those impacted by flooding or at risk of future flood events. The funder operates at the state level and focuses on ensuring long-term water resource sustainability, public safety, and infrastructure resilience. The primary purpose of this grant program is to finance projects related to flood damaged stream channel repair, stream channel improvement, flood risk reduction, and flood prevention. Eligible activities include physical repairs to stream channels, modifications to improve flow and reduce erosion, and preventative measures that mitigate the likelihood or severity of flooding. Projects must demonstrate either documented flood damage or credible risk conditions within a stream channel. The program prioritizes initiatives that not only address immediate damage but also contribute to long-term environmental and public benefits such as water quality improvements and ecological enhancements. Funding is provided on a cost-reimbursement basis, with the Idaho Water Resource Board contributing up to 50 percent of total project costs, capped at 200000 dollars per project. Applicants are required to provide matching funds, and proposals with higher cost-share contributions receive additional consideration during evaluation. Certain costs are ineligible, including expenses incurred prior to award, completed or ongoing projects at the time of application, and road-related infrastructure components such as signage or guardrails. Contracts are limited to a maximum duration of three years unless extended. Eligibility is restricted to public and quasi-public entities, including flood control districts, drainage districts, irrigation districts, canal companies, municipalities, counties, soil and water conservation districts, and other public entities. Applicants must submit comprehensive documentation demonstrating project need, including evidence of flood damage or risk, detailed project descriptions, cost estimates, timelines, and stakeholder engagement. Additional required materials include conceptual design documents, proof of insurance, and documentation of regulatory approvals or plans to obtain them. The application process requires submission of a complete proposal package, including a cover letter with project summary and funding request, a detailed application addressing multiple technical and administrative criteria, and supporting documentation such as maps, photographs, and cost-share breakdowns. Applications may be submitted via email, mail, or in person, and must be received by the stated deadlines. Evaluation is conducted using a 125-point scoring system that assesses project effectiveness, readiness, clarity, and cost-share contributions. Applications are reviewed by Idaho Water Resource Board staff and presented to the Finance Committee, with final funding decisions made during Board meetings. Successful applicants enter into a cost-reimbursement contract and must comply with reporting and documentation requirements throughout the project lifecycle. The program operates on a recurring annual cycle, with a regular application deadline on the first Friday of June and a supplemental round deadline in early January. This recurring structure allows applicants to plan future submissions if not funded in a given cycle.

Projects with higher than 50 percent cost share receive additional evaluation points; clearly demonstrate urgency and measurable benefits; ensure detailed cost estimates and stakeholder support
