Environment (Water Quality)

HB 258 updates Maryland's rules for development near the Chesapeake and Atlantic Coastal Bays. It requires local governments to conduct 10-year reviews of their critical area programs, sets specific location rules for new development (like maintaining 300-foot buffers from tidal wetlands), and mandates climate vulnerability assessments for projects. The bill also clarifies procedures for correcting mapping errors and updating tree replanting requirements. These changes directly affect 12 coastal Maryland counties (including Calvert and Talbot) that manage local development plans under the program. The law aims to strengthen protections for bay ecosystems through clearer, updated standards for land use decisions.
