HB 480 Maryland House of Delegates · 2025 Regular Session

St. Mary’s County – County Plans – Public Sewerage Systems and Water Supply Systems

HB 480 changes how St. Mary’s County must review and approve new or expanded public sewerage and water supply systems. It requires the St. Mary’s County Planning Commission to review these systems for consistency with county plans, hold a public hearing, and make specific findings on factors like engineering, economics, and compatibility with land use plans before the County Commissioners can approve them. This directly affects St. Mary’s County officials (Planning Commission and County Commissioners) by adding mandatory review steps for infrastructure projects. The bill takes effect October 1, 2025.
