Draft List of 3 acre properties


What is a "3-acre site?"

Draft General Permit 3-9050 serves as the “Three-Acre General Permit” as required under the Vermont Clean Water Act.  A “three-acre site” is an impervious surface of three or more acres that:

  • has never had an operational stormwater permit, or
  • was permitted to standards in place prior to the 2002 Stormwater Management Manual

The Stormwater Rule defines these sites as follows:

  • Impervious surface of three or more acres means a single tract of land with three or more acres of impervious surface;
  • a project on a tract or tracts of land that was previously authorized under a stormwater permit that authorized the discharge of stormwater from three or more acres of impervious surface; and
  • impervious surface adjacent to or adjoining the foregoing types of impervious surfaces where the surface in question are part of a related operation, such as a hospital, resort, or campus.
