Bill H.453, introduced by Representative Lalley of Shelburne, aims to amend the stormwater management rules to align with recent land use changes that promote increased development in high-density municipalities and neighborhoods. The bill mandates the Secretary of Natural Resources to revise stormwater permitting standards to support housing density in walkable areas. This includes incorporating innovative stormwater management practices, such as off-site management and alternatives for high-density development, as published by the U.S. Environmental Protection Agency.

The proposed changes are intended to facilitate the development of housing in urban settings while ensuring effective stormwater management. By updating the stormwater management manual and permitting standards, the bill seeks to create a framework that balances environmental concerns with the need for increased housing availability in densely populated areas.
