Basement Flooding From Snowmelt and Window WellsSpringville's spring water problem

Through winter, snow piles up on lawns, against foundations and inside window wells. When temperatures climb, it melts quickly, and the ground below may still be frozen or already saturated. Water that cannot soak in runs toward the lowest point it can find, which is often the gravel at the bottom of a window well or the soil against a basement wall.

Rain on snow makes it worse. A warm spring storm can melt a winter's worth of snow in a day or two. Springville's position at the foot of the mountains, with Hobble Creek carrying runoff from the canyon, means groundwater around many homes rises in spring as well.

Water that comes in from outside has passed through soil, mulch and lawn. Restoration contractors generally treat it as contaminated, which means carpet pad, carpet and the lower part of drywall that it touched are usually removed rather than dried in place. Concrete and framing are cleaned and dried.

That can be frustrating if the water looked clear. The reason is that the contamination is not visible, and the materials most likely to hold it are also the hardest to dry.

This is the hard part. Most homeowners policies exclude surface water and flooding, and many limit groundwater seepage. Flood insurance through the National Flood Insurance Program covers flooding, usually after a 30-day waiting period. ^[2] Read your policy, and ask your agent about flood coverage and sewer or drain backup endorsements before spring.

In late February or early March, before the big melt, walk around the house. Shovel snow away from the foundation, especially on the sunny side where it will melt first. Clear snow out of window wells and check whether the drain at the bottom is visible. Make sure downspouts are not buried and that their extensions are in place. If you have a sump pump, pour water into the pit to confirm it runs. These steps take an hour and prevent most spring basement floods.

If a window well fills during every storm, its drain is probably clogged or was never connected. Some wells have a gravel base with no drain at all, relying on the soil to absorb water. In clay soils or when the ground is frozen, that does not work. A contractor can clear or install a drain that connects to the perimeter drain or to daylight. A clear cover remains the simplest fix of all.

Basement bedrooms need egress windows for safety, and those windows sit in wells. If a bedroom window well floods, the bedroom is usually the first room hit. Keep beds and belongings off the floor near the window in spring, and make sure covers can still be pushed open from inside in an emergency.

Some basements will always be at risk in big snow years. If yours is one, store belongings on shelves or in plastic bins rather than cardboard on the floor, choose flooring that tolerates water, keep a wet-dry vacuum and a submersible pump on hand and know who to call.

Basement flooding tends to repeat in the same houses because the causes are physical and permanent: a low lot, a well on the uphill side, a downspout pointing at a wall. Fixing the cause breaks the cycle; cleaning up alone does not.

Even after snow is gone, groundwater can stay high for weeks. Seepage may continue into May in wet years. Keep checking the basement and run a dehumidifier.

Neighbors on the same street often flood in the same storms. Talking with them about which fixes worked can save a lot of trial and error. If several homes flood together, report it to Springville City Public Works in case a street drain or ditch is part of the problem.

Keep a simple flood kit near the basement stairs: a flashlight, rubber boots, gloves, a few heavy-duty trash bags, a bucket and the number to call. It turns a frantic search into a few calm minutes of action.
