Inland Wetlands and Watercourse

If your proposal is to develop land which contains wetlands/watercourses, or if your development is proposed to drain into a wetland, or your proposed activity is located within 100 feet of a wetlands or watercourse, or it otherwise determined by the Inland Wetlands and Watercourses Agency (IWWA) to likely impact a wetland, you may need to apply for a wetlands permit from the IWWA before or at the same time application is made to the Planning Commission, Zoning Commission, or ZBA.

The IWWA must render a decision on the wetlands application before the other Commissions/ Board can render their decision.

Whether or not your property contains wetlands or whether or not your proposal may be regulated by the IWWA can be discussed with the Assistant Planner/ Authorized Wetlands Agent.

A wetland/watercourse delineation may be required. This is a process in which a Connecticut licensed soils scientist is hired by the applicant to field locate the boundaries of wetland soils and watercourses on your site, which would then be and plotted on your site plan by a land surveyor or engineer.

If you have wetlands on your property or your activity may impact a wetland, there are four possible ways that your proposal can be reviewed and/or proposed:

1. Administrative Ruling.
The Authorized Agent will make a site visit and determine that there will be no wetlands impact and no further application will be required, or will determine that the activity is within his/ her authority to review and act upon administratively.

2. Referral to the IWWA
The Authorized Agent may refer your project to the IWWA. At a meeting, the IWWA will decide if you will be required to submit a permit application.

3. Application.
If your proposed activity is within a wetlands or watercourse, or is determined likely to impact a wetland/watercourse, you will be required to obtain a wetlands permit.
