Substitute House Bill No. 7153 establishes two new infrastructure improvement districts: the Port Eastside Infrastructure Improvement District in East Hartford and the Park City Landing Infrastructure Improvement District in Bridgeport. The bill outlines the formation process, which requires a petition from eligible voters and may involve a referendum for approval. Key provisions include the ability for the districts to levy taxes, assess benefit assessments on properties that benefit from improvements, and issue bonds—up to $125 million for the Port Eastside district and $190 million for the Park City Landing district. The bill also introduces new legal language regarding governance structures, including the election of district officers and the requirement for public hearings on assessments, while deleting outdated provisions that may conflict with the new framework.

Additionally, the bill emphasizes transparency and accountability by mandating regular reporting on project statuses and financial disclosures to residents and developers. It streamlines the approval process for state agency actions related to district improvements and clarifies the appeal process for decisions made by the commissioner overseeing these improvements. The bill also establishes specific requirements for the termination of districts, ensuring that all debts are settled before dissolution unless the municipality agrees to assume them. Overall, the legislation aims to enhance the operational and financial capabilities of the districts while ensuring community involvement and adherence to legal standards.
