Spring Rainfall, Snow Melt Can Cause Flooding
FEMA urges New Englanders to be prepared
Release Date: February 24, 2009
Release Number: R1-09-004
Boston - Throughout New England, residents are at risk from flooding during spring - the time of year when the warming sun and increased rainfall begin melting the winter snow pack, releasing its often high water content. The Department of Homeland Security's Federal Emergency Management Agency (FEMA) urges New England residents to be prepared.
"The stage is set for spring flooding. Until the hard, frozen ground completely thaws, any melting snow or rainfall cannot readily penetrate into the ground, and the resulting run-off can overfill streams and rivers," said Kevin Merli, Director of FEMA's Region I Mitigation Division, which covers New England.
Before the threat of flooding becomes imminent, flood mitigation experts advise individuals to:
- Purchase a flood insurance policy now. Homeowner insurance policies do not include flood loss and there is a 30-day waiting period for flood coverage to become effective. Call your insurance agent to find out about flood insurance.
- Make sure downspouts carry water several feet from your house to a well-drained area. About 2,500 gallons of water will come from a 1,000 square foot roof with one foot of snow depth across the roof. This much water may cause problems if allowed to drain next to the house.
- Move snow on the ground away from the house. Water from the snow may cause a wet basement if allowed to run down along the basement wall. If the ground is sloped 1 inch per foot near the house, moving the snow just 3-5 feet from the house will reduce problems.
- Examine and clean your sump pump, if you have one. Test your sump pump by pouring water into the pit. Make sure the discharge hose carries the water several feet away from the house to a well-drained area. Also make sure that the pipe is on sloped ground so it drains to prevent it from freezing.
- Remove snow from around rural yards to minimize soft, wet soil conditions. Remember that a 20-foot diameter 10-foot high pile of snow contains about 2,600 gallons of water. Move the snow to well drained areas.
- Be aware of local evacuation routes.
