2023 Connecticut General Statutes › Title 22a - Environmental Protection › Chapter 444 - Coastal Management › Section 22a-94. - Coastal area; coastal boundary. Commissioner to prepare maps.

(a) The Connecticut coastal area shall include the land and water within the area delineated by the following: The westerly, southerly and easterly limits of the state's jurisdiction in Long Island Sound; the towns of Greenwich, Stamford, Darien, Norwalk, Westport, Fairfield, Bridgeport, Stratford, Shelton, Milford, Orange, West Haven, New Haven, Hamden, North Haven, East Haven, Branford, Guilford, Madison, Clinton, Westbrook, Deep River, Chester, Essex, Old Saybrook, Lyme, Old Lyme, East Lyme, Waterford, New London, Montville, Norwich, Preston, Ledyard, Groton and Stonington.
(b) Within the coastal area, there shall be a coastal boundary which shall be a continuous line delineated on the landward side by the interior contour elevation of the one hundred year frequency coastal flood zone, as defined and determined by the National Flood Insurance Act, as amended (USC 42 Section 4101, P.L. 93-234), or a one thousand foot linear setback measured from the mean high water mark in coastal waters, or a one thousand foot linear setback measured from the inland boundary of tidal wetlands mapped under section 22a-20, whichever is farthest inland; and shall be delineated on the seaward side by the seaward extent of the jurisdiction of the state.
(c) The coastal boundary as defined in subsection (b) of this section shall be shown on maps or photographs prepared by the commissioner which supplement flood hazard rate maps prepared by the United States Department of Housing and Urban Development under the National Flood Insurance Act. Such maps shall be sufficiently precise to demonstrate whether the holdings of a property owner, or portions thereof, lie within the coastal boundary. Copies of such maps or photographs shall be filed with the commissioner and with the clerk of each coastal municipality.
(d) The maps described in subsection (c) of this section shall be promulgated not later than July 1, 1980. Prior to final adoption of any map, the commissioner shall hold a public hearing in accordance with the provisions of chapter 54 within the applicable coastal town. The commissioner may use interim maps prepared on United States Geological Survey Topographic base at a scale of one to twenty-four thousand or their metric equivalent. In preparing such interim maps, the commissioner may use any man-made structure, natural feature, property line, preliminary flood hazard boundary maps as prepared by the United States Department of Housing and Urban Development, or a combination thereof which most closely approximates the landward side of the boundary. Further, the commissioner may use city or town property tax maps or aerial photographs, state tidal wetlands photographs, or similar maps of property delineation as they are available.
(e) The commissioner may, from time to time, amend such maps described in subsection (c) of this section. Prior to the adoption of an amendment to any map, the commissioner shall hold a public hearing in the affected municipality in accordance with the provisions of chapter 54. The commissioner shall consider for amendment changes in the boundary petitioned by the coastal municipality, by any person owning real property within the boundary, or by twenty-five residents of such municipality. The commissioner shall approve, deny or modify such petition within sixty days of receipt and shall state, in writing, the reasons for his action. All amendments to the boundary shall be consistent with subsection (b) of this section.
(f) A municipal coastal boundary may be adopted by the municipal planning commission of each coastal municipality in accordance with the notice, hearing and other procedural requirements of section 8-24. Such boundary may be delineated by roads, property lines or other identifiable natural or man-made features, provided such boundary shall approximate and in no event diminish the area within the coastal boundary as defined in subsection (b) of this section and as mapped under subsection (d) of this section. Such boundary shall be sufficiently precise to demonstrate whether the holdings of a property owner, or portions thereof, lie within the boundary. Upon adoption, such boundary shall be submitted to the commissioner for mapping in accordance with subsection (c) of this section. The municipal planning commission may, at its own discretion or upon request of a property owner, amend the coastal boundary in accordance with the procedures and criteria of this subsection.
(g) All property lying within the coastal boundary shall be subject to the regulatory, development and planning requirements of this chapter.
