Stream Alteration Permits


Stream alteration permits regulate activities that take place in or along streams. The permit program is intended to prevent the creation of flood hazards, protect against damages to aquatic life, and protect the rights of neighboring landowners. The types of activities that are regulated include streambank stabilization, road improvements that encroach on streams, bridge construction or repair, and utility crossings under streambeds.

The program is authorized in 10 V.S.A. Chapter 41. A permit is required for movement, excavation, or fills involving 10 or more cubic yards annually in any perennial stream. See program Guidance for the Identification of Perennial Streams.

The Agency of Natural Resources has adopted a Stream Alteration Rule pursuant to 10 V.S.A. § 1027 and 10 V.S.A. Chapter 165.  This Rule applies to stream alterations in both emergency and non-emergency circumstances.

The Program has issued a General Permit pursuant to 10 V.S.A. §7501 for stream alteration activities. The purpose of this general permit is to ensure that all stream alteration activities are regulated efficiently and effectively in accordance with the requirements of 10 V.S.A. Chapter 41 and the Stream Alteration Rule.
