Spring Runoff Checklist for Utah County Homeowners

Reviewed by Tyler Bennett, Restoration Project Manager, IICRC WRT/ASD #291438, October 2026.

Short answer: Spring runoff in Utah County peaks from mid-March through May and causes basement floods, window-well overflow, and crawlspace moisture every year. A one-hour check in late February or early March catches most of the problems before they cost thousands. This is the checklist we give homeowners who have had a basement flood and don’t want another one.

Why spring runoff hits Utah County hardest

Utah County sits downstream from the Wasatch snowpack. When temperatures warm in March and April, snow melts faster than the ground can absorb it, local streams and the water table rise, and water finds every weak spot in a home’s drainage. Spanish Fork, Mapleton, and Salem see consistent spring issues because of elevation changes that funnel water to specific neighborhoods.

The 10-point spring runoff checklist

1. Clean window well drains. Remove leaves, dirt, and debris from the gravel bed. The drain should actually drain.
2. Check window well covers. Replace cracked or missing covers. These should shed water, not collect it.
3. Verify grading slopes away from the foundation. The first 10 feet from the house should drop at least 6 inches. Flat or back-sloped ground directs water to the foundation.
4. Clean gutters and verify downspout extensions. Clogged gutters overflow at the foundation. Downspouts should discharge at least 4-6 feet from the house.
5. Test the sump pump. Pour a bucket of water into the sump pit. The pump should kick on and clear the water. If it doesn’t, replace it before spring.
6. Test sump battery backup. If you have one. Battery backups fail silently; test them yearly.
7. Look for foundation cracks. Hairline cracks in concrete block or poured foundations become water paths when the water table rises. Seal with a hydraulic cement or urethane injection kit.
8. Check basement humidity. Place a hygrometer in the basement. Above 50% means mold-friendly conditions. A dehumidifier helps.
9. Inspect the sewer cleanout. If you have one in the yard, make sure the cap is tight. A loose cap allows surface water to enter the sewer system.
10. Clear window well drains again in April. Spring winds move more debris into them.

What to do if runoff still gets in

1. Shut off power to any wet basement area at the breaker.
2. Call 4Sure immediately. 24/7 live-answered, 45-minute arrival in Spanish Fork.
3. Lift what you can off the water. Boxes, furniture, rugs.
4. Photograph everything for insurance (though note: groundwater and surface water are usually not covered by standard homeowners — they need separate flood insurance).

Insurance clarity for spring runoff

Standard Utah homeowners policies do not cover damage from groundwater, river or stream flooding, or surface water from runoff. That requires a separate flood policy through FEMA’s National Flood Insurance Program (NFIP) or a private carrier. Flood policies have a 30-day waiting period after purchase, so buying one in March for a spring runoff risk is already too late for that year.

Homeowners policies do cover damage from a sump pump failure that led to basement flooding — if you have the water backup endorsement. Check your policy declarations. If it is not there, add it (typically $40-$150/year) for next year.

Signs runoff is getting in

• Damp spots or darkening at the bottom of basement walls
• Water at the base of window wells or on window sills
• White crystal deposits on concrete (efflorescence)
• Wet carpet along exterior walls
• A musty smell after warm days

After runoff season

• Check the basement for stains, warped baseboard and musty smells
• Look behind boxes and furniture stored against exterior walls
• Run a dehumidifier if humidity stays over 50%
• Fix grading and downspouts that sent water toward the house

Common questions

When is spring runoff season in Utah County?

It usually runs from late winter through spring, as snowpack melts and the ground stays saturated. Heavy spring rain on top of melting snow is when basements take on the most water.

Does homeowners insurance cover groundwater in the basement?

Usually not. Surface water and groundwater are commonly excluded, and flooding needs a separate flood policy. Sudden failures, such as a burst pipe, are treated differently. Read your policy’s water exclusions.

Does a sump pump need maintenance?

Yes. Test it before runoff season by pouring water into the pit, make sure the discharge line is clear and drains away from the house, and consider a battery backup.

What if water already got in?

Remove standing water fast and start drying within 24 to 48 hours to keep mold from starting. Inside Spanish Fork city limits, 4Sure arrives within 45 minutes.
