Relating to powers of regional transportation authorities.

SB 1557 creates a "General Mobility Program" allowing municipalities within regional transportation authorities to use up to 25% of local sales and use tax revenue for transportation improvements. The program funds projects like sidewalks, bike trails, streetlights, traffic signals, and drainage work related to roads. Municipalities must agree with their subregional board, submit annual project lists, and receive funds in two installments (50% upfront and 50% reimbursed by year-end). Unused funds must be applied toward paying down debt secured by a 1% sales tax rate. This bill directly affects municipalities in regional transportation authorities with subregional boards.
