An act relating to stormwater management

This bill extends the deadline for owners of impervious surfaces (like paved areas over 3 acres) to obtain stormwater permits from 2027 to 2036. It allows municipalities that assume full control of stormwater systems to charge users impact fees to cover system costs. The bill also extends a 0.22% clean water surcharge on property transfers until 2036 and creates a grant fund to help municipalities manage stormwater projects in residential areas or "orphan" systems. These changes primarily affect property owners, municipalities, and developers involved in stormwater management.
