Conn. Gen. Stat. § 7-147

(b) The legislative body or such board, commission, department or inland wetlands agency may grant or deny permission based on a finding of the effect of the obstruction or encroachment on the flood-carrying and water storage capacity of the waterways and flood plains, flood heights, hazards to life and property, the protection and preservation of the natural resources and ecosystems of the municipality including, but not limited to, ground and surface water, animal, plant and aquatic life, nutrient exchange and energy flow with due consideration given to the results of similar encroachments constructed along the reach of the waterway. Wherever there is a city or borough within a town, the town shall have authority to establish such lines for such of its area as is not within such city or borough, and the city or borough shall have such authority within its boundaries. Any two or more adjoining municipalities shall have authority to investigate jointly the desirability of establishing lines on either or both sides of a waterway within their jurisdiction. Any private person or any firm or corporation aggrieved by any decision of a legislative body or any such board, commission, department or inland wetlands agency made in accordance with this section may, within thirty days after notice thereof, appeal from such decision in the manner provided by section 8-8 for appeal from the decisions of a municipal zoning board of appeals. Nothing contained in this section shall limit or restrict the Commissioner of Transportation in exercising his authority over the harbors and navigable waters of the state, nor apply to any dam, bridge, pipeline or other similar structure, and appurtenances thereto, extending across any waterway, which are otherwise in compliance with law.

(c) The provisions of this section shall not be construed to limit or alter the authority of the Commissioner of Energy and Environmental Protection over the tidal, coastal and navigable waters of the state and within stream channel encroachment lines established by said commissioner pursuant to section 22a-343 .

Statute held constitutional; proper standard for delegation of power to municipality is whether delegation provides reasonable notice of what conduct may be authorized or prohibited. 209 C. 652. Cited. 217 C. 588.
