The primary purpose of the Inland Wetlands and Watercourses Commission is the protection, preservation and maintenance of Plainville's wetlands and watercourses. The preservation of these resources is linked to improved ground and surface water quality, increased flood prevention and the protection of habitat for the use and enjoyment of wildlife and people. The Commission establishes wetland regulations and boundaries, and decides upon petitions for changes to the regulations. The Commission reviews and acts on requests for permits to conduct activities inside designated wetlands and within their surrounding 100 foot upland review area. The Commission also enforces the Inland Wetlands and Watercourses Regulations of the Town of Plainville.
