Coastal Inundation and SLOSH Maps

The Connecticut coastline is susceptible to flooding from both river floods and coastal storm effects, with over many permanent residents and additional seasonal residents. 

The US Army Corps of Engineers has created Sea, Lake, and Overland Surge from Hurricanes (SLOSH) maps for each Connecticut coastal community, and those have been included as attachments below for planing purposes.
