Highway Safety Improvement Program – County Safety Program

Only counties or tribes in Washington State are eligible to apply. Other organizations may work with a county or tribe to propose/develop a project.

Preliminary engineering/design, right-of-way, and construction phases of projects are eligible for funding. Design-only projects that include only preliminary engineering, environmental, and/or right-of-way phases are not eligible.

Counties or tribes must submit a local road safety plan that addresses fatal and serious injury crashes in the county/tribe to be eligible to apply. Local road safety plans are a Proven Safety Countermeasure that provide a data-driven analysis and prioritization of an agency’s roadways for traffic safety. Using specific information about the factors present at specific crash locations, the county/tribe must identify locations where those factors are present. They then must identify and prioritize improvements/countermeasures/projects to address the highest priority locations. This prioritized list of projects must be presented in the local road safety plan, which must be submitted with the application. The local road safety plan must document how and why the priorities were selected.

Projects are eligible for 100% federal HSIP funding for all phases authorized prior to April 30, 2028. Any phases not authorized by this date may be subject to the remaining funds being rescinded.

Projects must be fully funded between this funding and other funding sources, as applicable.

Only one application per county/tribe may be submitted. All prioritized projects should be shown on the single application.

There is no maximum funding level for the application.

Projects must comply with all necessary federal and state requirements as detailed in the Local Agency Guidelines Manual.

Projects must be completed as selected once they have been awarded funding.

Recipients must report biannually on the status and expenditures of each project.

Recipients are required to submit monthly progress billings for projects to ensure timely reimbursement of eligible federal expenditures.

Costs incurred prior to federal fund obligation are not eligible for reimbursement.

Projects that are not actively pursued or that become inactive (23 CFR 630) are at risk of being cancelled and the funds reprogrammed.

All county projects must be ADA compliant upon completion or federal funds must be repaid.
