Substitute Senate Bill No. 448 proposes significant amendments to the charter governing The Metropolitan District of Hartford County, set to take effect on October 1, 2026. Key changes include the elimination of the requirement that officers of boards, bureaus, committees, and commissions be appointed from their own membership, thereby allowing for more flexible leadership appointments. The bill also clarifies that district employees are prohibited from serving on the board of commissioners or related committees. Additionally, it updates terminology from "commission" to "board" and mandates that proposed ordinances be published in full in a widely circulated newspaper, with specific provisions for summaries, while ensuring that ordinances requiring appropriations cannot be summarized. The maximum fine for ordinance violations is increased from $50 to $250, and the threshold for requiring written contracts for public works or supplies is raised from $25,000 to $50,000.

Further amendments focus on financial management and regulatory authority within the district. The bill introduces new provisions for determining each town's average total revenue based on annual audits, with penalties for non-compliance, and allows the district treasurer to report neglect in tax collection to the superior court. It also enhances the authority of the Metropolitan District's water bureau to create binding regulations and enforce penalties, increasing fines for violations from $30 to $250. Additionally, the time frame for municipalities to file assessment caveats is extended from 30 to 90 days, and the permissible term for liens related to sewer connection charges is extended from 15 to 20 years. Overall, these amendments aim to improve transparency, governance, and financial accountability within the Metropolitan District.
