Flood-zone regulation is governed by FEMA's National Flood Insurance Program, the Connecticut Coastal Management Act under Conn. Gen. Stat. Sec. 22a-90 through 22a-112, the Connecticut Inland Wetlands and Watercourses Act under Conn. Gen. Stat. Sec. 22a-36 through 22a-45, and the state Flood Management Act in Conn. Gen. Stat. Chapter 476a (Sec. 25-68b et seq.).
