Inland Wetlands

What We Do
The inland wetlands and watercourses of the State of Connecticut are an indispensable, irreplaceable, and fragile natural resource with which the citizens of the State have been endowed.  The wetlands and watercourses are an interrelated web of nature essential to:

                 - Hydrological stability and control of flooding and erosion
                 - Recharging and purification of groundwater
                 - The existence of many forms of animal, aquatic and plant life

The preservation and protection of the wetlands and watercourses from random, unnecessary and unregulated uses, disturbance or destruction which is in the public interest and is essential to the health, welfare and safety of the citizens of the Town.
