Are you working near a pond, wetland, stream, salt marsh, or the ocean?
Then you need to determine which permits are needed before any work begins
If your property abuts a salt mash, pond, stream or mucky area; if there is standing water at any time of the year within 50 feet of your project; and/or if your project entails crossing a stream or wet area, you may need a State Wetlands Permit, a State Shoreland Permit and/or a Town Special Permit for your project.
The Town's Wetland Regulations are found on Page 17 of the Zoning Ordinance here.
The following flow charts are helpful guides for determining which permits are necessary for your project. Every project scope and location is different.
