H.453 is a bill introduced by Representative Lalley of Shelburne that aims to amend the stormwater management rules to better align with recent land use changes that promote increased development in high-density municipalities and neighborhoods. The bill mandates that the Secretary of Natural Resources revise the 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 regulatory framework that accommodates the growing demand for housing in densely populated areas, thereby promoting sustainable development practices.
