Transportation Improvement Program

As the designated Metropolitan Planning Organization (MPO) and Regional Transportation Planning Organization (RTPO) for Whatcom County, WCOG is required to prepare a Transportation Improvement Program (TIP) every year in cooperation with WCOG’s members and the Washington State Department of Transportation.  The TIP provides a comprehensive six-year listing of transportation improvements within the county that are included on the regional transportation network as defined by the region’s long-range transportation plan – Way to Go, Whatcom

The WCOG TIP also serves as a schedule of accountability to the Federal Highway Administration (FHWA) and the Federal Transit Administration (FTA), who annually review and certify the TIP to ensure the continuation of federal financial assistance for transportation improvements in the region.

The WCOG TIP works in concert with the Statewide Transportation Improvement Program (STIP) to implement projects.  Placement in the STIP is required for most transportation projects that receive federal funding.

TIP projects are separated into three distinct groups:

  1. Projects with secured funding anticipated and are located within the Metropolitan Planning Area.
  2. Projects with secured funding but are located outside the Metropolitan Planning Area.
  3. Unfunded projects (without dedicated funding source) for the entire WCOG region.

Regionally Facilitated Surface Transportation Block Grant and Transportation Alternatives Programs

With guidance from the WCOG Transportation Policy Board (WTPB) and Transportation Technical Advisory Group (TTAG), WCOG staff facilitates a selection process to award annually allocated Federal Surface Transportation Block Grant (STBG) and Transportation Alternatives (TA) programs funds to qualifying projects.  The biennial process is continuously and collaboratively assessed for consistency with Whatcom Mobility 2040 goals and federal performance management standards.  Projects are scored and prioritized by TTAG members through a qualitative and quantitative application process.  Final project prioritization and federal funding awards are determined by the Whatcom Transportation Policy Board.

WCOG is responsible for implementing a targeted amount STBG and TA funds on an annual basis.  On October 13th, 2021, the Whatcom Transportation Policy Board adopted the WCOG Obligation Authority Management Process to facilitate coordination efforts necessary to ensure successful delivery of STBG and TA funding.
