Full Breakdown

Conn. Gen. Stat. Sec. 22a-90 through 22a-112 establish the Connecticut Coastal Management Act, which governs all development within the legally defined coastal boundary along Long Island Sound and tidal waterways. Site plans within the coastal boundary undergo coastal site plan review evaluating impacts on coastal resources, public access, and shoreline flood and erosion. Structures waterward of the high tide line require a DEEP Office of Long Island Sound Programs permit under Sec. 22a-359. Municipalities incorporate the Act into local zoning, but cannot waive consistency review or DEEP jurisdiction.

Violations & Penalties

Unauthorized coastal work may incur civil penalties up to $10,000 per day plus mandatory removal and restoration. Tidal wetlands violations carry separate penalties under Sec. 22a-32.

Frequently Asked Questions

Do I need a state permit to build a dock or seawall?

Yes. Any structure waterward of the coastal jurisdiction line requires a DEEP Structures, Dredging and Fill permit. Local approvals alone are insufficient for work in tidal waters.

Can my town approve coastal projects DEEP would deny?

No. Municipal approvals cannot override DEEP jurisdiction over tidal waters and wetlands. Coastal site plan review must apply state consistency standards alongside any required DEEP permit.
