Ridgeside - Subject to local approval, repeals and replaces in its entirety the city's private act charter. - Amends Chapter 615 of the Private Acts of 1931; as amended.

HB 1439 replaces Ridgeside's entire municipal charter, which had been amended multiple times since 1931, with a new charter document. It updates the city's corporate name, boundaries (correcting a reference to a church in the boundary description), and explicitly lists 13 core powers the city retains, such as taxing, borrowing, issuing bonds, and exercising eminent domain. The bill directly affects Ridgeside's local government structure and governance authority. As a procedural charter amendment (not a new policy), it does not change existing city services or create new obligations, but formalizes the city's legal framework under current state law. The bill was signed into law on June 4, 2025.
