An act relating to changes to Act 250

H.737 amends Vermont's Act 250 land use law to clarify that constructing roads for property access counts as "development" under the law, but exempts state/municipal roads, utility corridors, and roads primarily used for farming or forestry. It also revises the definition of "Tier 3" areas (critical natural resources zones) to require justification for housing development there, unless a town plan already designates land for housing with evidence of minimal environmental harm. The bill mandates the Land Use Review Board to create rules by July 2027 on how municipalities can object to road projects near roads or agricultural land. Most provisions take effect July 1, 2026, with the key definition change delayed until December 31, 2026. These changes directly affect developers, municipalities, and landowners seeking to build housing or infrastructure near natural resources or roads.
