Municipal approval of guideway plans required, municipalities allowed to revoke approval, and requesting of federal funds prohibited until municipal approval is received.

HF 1873 requires transit agencies to obtain written approval from all affected cities, counties, and towns before requesting federal funds for transit guideway projects. Municipalities must review preliminary and final design plans within 45 days (or 60 days for final changes), and can request specific modifications if disapproving. Cities, counties, or towns may revoke approval at any time before federal funding is secured, triggering a review process similar to initial disapproval. The bill applies to all transit guideways except light rail projects and prohibits federal funding requests until all local approvals are secured.
