Cornwall is subject to flooding hazards. Its based on a number of factors including rainfall, topography, flood control measures, river flow and tidal surge data, and changes due to new construction and development.

Note standard homeowners insurance does not cover flooding. The lower the degree of risk, the lower the flood insurance premium. For information pertaining to flood insurance, flood maps and other flooding risks visit

To prepare for a flood, you should:

  • Build an Emergency Supply Kit, see our Build A Kit information pertaining to Flooding under the Prepare section of our site.
  • Avoid building in a floodplain unless you elevate and reinforce your home. Or take steps to establish water barriers.
  • Elevate the furnace, water heater and electric panel in your home.
  • Consider installing "check valves" to sewage and sanitation plumbing to prevent flood water from backing up into the drains of your home.
  • If possible and reasonable, construct barriers to stop floodwater from entering the building and seal walls in basements with waterproofing compounds.
