Community information Volusia County is located in the central portion of the Florida east coast. The land area of Volusia County is approximately 1,210 square miles, with 50 miles of Atlantic Ocean shoreline. Along the eastern side of the county, the Halifax River and Indian River/Mosquito Lagoon form long, narrow estuaries which separate the county’s mainland from its barrier island. Ponce DeLeon Inlet, located near the middle of the coastline, serves as the county’s only inlet through the barrier island and the major passage through which Atlantic Tides and storm surge propagate into the estuaries. The Tomoka River and St. Johns River are other major estuaries located in the county. Volusia County has a subtropical climate, with long, warm, and humid summers and short, mild winters. The average annual participation is approximately 48 inches. Over half of this rainfall occurs from June 1 through November 30, the Atlantic hurricane season. 2. Types, causes, and sources of flooding Flooding in Volusia County results from tidal surges associated with hurricanes, northeasters, and tropical storm activity and from overflow from streams and swamps associated with rainfall runoff. Major rainfall events occur from hurricanes, tropical storms, and thundershowers associated with frontal systems. During periods of intensive rainfall, smaller streams tend to reach peak flood flow concurrently due to a relatively short time of concentration, with elevated tailwater conditions associated with coastal storm surge. This greatly increases the likelihood of inundation of low-lying areas along the coast.
