Any transit agency in Washington state is an eligible applicant. A transit agency is defined as:

• City transit system under RCW 35.58.2721 or chapter 35.95A RCW
• County public transportation authority under chapter 36.57 RCW
• Metropolitan municipal corporation transit system under chapter 36.56 RCW

Eligible projects and related costs

Vehicles, equipment, and zero-emission transition plan applications must be two-year projects only. Construction projects may be two or four years.

Capital projects and related expenditures may include:

• Electrification of transit vehicle fleets, including battery and fuel cell operated electric vehicles.
• Updating or modifying facilities for fleet electrification and/or hydrogen refueling infrastructure.
• New facilities that directly and primarily support fleet electrification.
• Construction of charging and fueling stations to support transit fleet electrification.
• Necessary upgrades to electrical transmission and distribution systems.
• In-house staff directly managing a capital construction project.
• Acquisition of property rights for capital projects.

Zero-emission fleet transition planning activities may also be an eligible project (contingent upon legislative appropriation of funding).

Match requirement

Applicants must provide matching funds in the form of direct contributions at a certain percentage of total project costs. Direct contributions are cash or assets that directly benefit the project and are fundamental to implementing the project.

The Green Transportation Capital Grant program uses a tiered match system to determine the minimum required match an applicant must provide. Match is determined by the transit agency's most recent operating budget.

Previous eligible expenditures directly associated with the proposed project may qualify as match. With the exception of competitive state-funded grants administered by WSDOT’s Public Transportation Division, applicants may use other grants as match.

Evaluation process

We use a competitive process for awards from the Green Transportation Capital Grant program. Designated members of the Green Transportation Capital Grant Advisory Committee will review applications and recommend projects for award to us. The committee includes representatives from WSDOT; Department of Ecology; Department of Commerce; Utilities and Transportation Commission; Washington State University; and large urban, small urban, and rural transit agencies.

Evaluation criteria

The maximum score on an application is 100 points. Each criterion can receive a maximum of 20 points.

Criterion for the Green Transportation Capital Grant program include:

• Project description: Responses clearly describe the project scope of work, goals, measurable objectives, and anticipated results.
• Scalability, sustainability, and support: Responses clearly describe how the project advances the green transportation goals of the transit agency, the scalability of the project, and the extent to which the transit agency has coordinated with necessary partners to successfully implement the project.
• Project benefits: Responses connect project benefits to reductions in carbon emissions, including how the project addresses environmental harms and provides environmental benefits for overburdened communities and vulnerable populations.
• Project budget and cost effectiveness: Project's request for grant funds is reasonable and reductions in carbon emissions provided by the proposed project are cost effective.
