Public Comment Period for Proposed WAC Changes
TIB is proposing various revisions to chapters 479-05 and 479-14, the board’s reimbursement of engineering costs, right-of-way eligibility, and small agency reimbursements.
Proposed changes may include, but are not limited to the following:
479-05
- Small agency retainage requirement. (Small agencies are cities less than 5,000 population.) In addition to small agency match requirements, the proposed WAC requires small agencies to retain $5,000 in contingency funding when receiving a TIB grant. If a project has cost increases, the Executive Director or Board may require the small agency to use the $5,000 in contingency funding before receiving additional TIB funds.
- TIB is transitioning from a fixed thirty percent reimbursement for design and engineering costs to an adopted Board reimbursable table for design and engineering costs of the approved contract bid amount. The Board shall, at a minimum, review and adopt a new table every two years. The new schedule would become effective June 1, 2026.
479-14
- Allowing Right-of-Way reimbursement for Active Transportation Programs. This change is now consistent with TIB’s other programs.
The WAC Changes as submitted to the Office of the Code Reviser are as follows:
