Spring Flooding | Know the Risk for Your Home

Spring flooding doesn’t just affect homes located near bodies of water. The snow, ice, or rain in your own backyard can sometimes become a flood in your home.

In 1996, the northeastern U.S. experienced extreme flooding after heavy snowfall thawed quickly, followed by heavy rains, according to the United States Geological Survey (USGS). Rivers flooded from New York to Virginia. In some areas, the rivers jammed with ice, creating more flood damage to buildings and homes nearby.

While such large-scale events of flooding caused by snow melt are rare, smaller cases of flooding — such as in a low-lying neighborhood or your basement — are quite common during late winter and spring.

So while April showers may be famous for bringing May flowers, spring rains also can lead to flooding. Here’s how to prepare and protect your home this spring.

What Causes Spring Flooding?

“Each cubic foot of compacted snow contains gallons of water.”

– Federal Emergency Management Agency (Fema)

In the western U.S., as much as 75% of the water supply derives from melting snow, which releases water into rivers during the warmer seasons, according to the USGS.

One of the problems, according to FEMA, is that warmer temperatures cause snow to melt and create runoff quickly. With the land still frozen, water easily runs off the surface and fills lakes and streams. These bodies of water begin to spill over their banks. Add seasonal storms to the mix, and the result can be springtime floods.

Many people who do not live near water assume that spring flooding will not affect them, but keep reading.

Flooding from spring rains and snow melt is not limited to coastal and riverside areas. When snow melt occurs in your yard, especially when it’s followed by heavy spring rains, the water must find a place to go. Often, it will flow into a home’s basement, crawl space or lower level.

Water always runs from higher ground to lower ground. If the ground around your home becomes saturated, the water may start seeping into your home through:

  • Windows
  • Doors
  • Cracks in the foundation

Even if you live in an area that does not get significant snowfall, spring flooding can still be a concern when heavy rains come.

Preparing for Spring Floods

It may not be possible to prevent water damage under all circumstances, but there are a number of steps homeowners can take to prepare their homes for common flooding caused by spring thaw. Consider taking some or all of the following precautions:


1. Install a Pump
A sump pump or sewer backflow valve can help keep water from pooling in your basement. It may be a good idea to have a battery-powered backup pump on hand, in case a storm causes a power outage.

2. Check for Leaks
Routinely check around all doors and windows for potential leaks. Inspect your foundation to see if you can find any cracks that may allow water to seep in. If you do see cracks or leaks, have them repaired as soon as possible. While you can repair a foundation crack yourself by sealing it with hydraulic cement, such do-it-yourself solutions are usually only temporary. Within a few years, you’ll need to call a foundation expert.

3. Remove Debris
It’s common for leaves, branches and other debris to collect in window wells, gutters, downspouts and other areas around your home. Be sure to remove wet leaves and other debris, as it can slowly add pressure and wear away paint, rot wood, or lead to cracks or leaks. When debris is allowed to pile up in gutters and downspouts, water will run off the roof, pooling near your foundation where it can cause mold growth and foundation cracks and damage. If gutter debris freezes and causes ice dams, it may prevent water from draining properly and provide opportunities for water to seep into your home.

4. Check Your Landscape
If at all possible, the grading of your yard should encourage water to flow away from your home, not toward your home. If there are areas where your lawn or landscaping dips toward your home, regrade those areas to direct water away from your house. Also, make sure you trim trees and bushes near your home so that branches aren’t leaning on or over the house. Remove tree trimmings or grass clippings from next to the house, as they could hold water and encourage leaks.

5. Inspect Your Roof
It’s important to keep your roof in good condition. If you’ve left fall leaves to pile up on your roof, they will gradually wear down the shingles. When melting snow and rain come, you’ll be more likely to experience a leak. If you think you may have shingles missing or damage to your roof, call a local roofing company. Most will inspect your roof for no charge to see if you need to make a repair.

6. Remove Valuables from Lower Levels
If you use your basement or cellar for storage, avoid keeping electronics, photo albums or other items down there as they could be damaged by water — and difficult to replace.

 

Protecting Your Property From Spring Floods

In most cases, standard homeowner’s insurance policies do not cover flooding. Instead, homeowners who want to protect their homes against flood damage must purchase a separate flood insurance policy. It’s important to understand what flood insurance covers, for example, in a basement.

About Flood Insurance

Flood insurance sold by insurance companies is regulated by the National Flood Insurance Program (NFIP). Regardless of which insurance provider you choose, your flood insurance rates will be set by the national flood program. Consider choosing the provider you believe will offer the best service for you and your home especially when it comes to filing a claim.

Even if you’re not a homeowner, you may want to consider purchasing a flood insurance policy. Flood coverage can be added to renters and condo policies, helping ensure that your belongings would be protected from flood water damage.
