19 V.S.A. § 1510: Local authorization

(a) In any case of proposed highway construction in which a federal-state-local match is contemplated, a municipality seeking to reserve the State portion of monies for the construction project must obtain ratification of the local portion, as this portion may be periodically assessed by the Agency of Transportation, within 18 months of receipt of a commitment on the part of the State, as evidenced by a signed application relative to engineering costs and project costs or similar document. In the event ratification of the local portion is not obtained within the 18 month period, the State shall withdraw from the proposal and shall make the State portion available for other program purposes.

(b) No second or subsequent application relative to engineering costs and project costs or similar document may be signed by a State official unless 18 months have passed since an earlier signing of a similar application relative to engineering costs and project costs for the same proposed highway project.
