Salt Lake City may be known for dry summers, but when storms roll in, they hit hard and fast. Monsoon season, typically beginning in mid-July, brings sudden downpours and localized flash flooding that can catch homeowners off guard.
In areas like Millcreek, West Jordan, and Holladay, where aging storm drains and sloped neighborhoods are common, a 20-minute cloudburst is all it takes to flood basements, overwhelm sump pumps, and send water rushing through crawl spaces. If your home isn’t ready, the damage can be extensive—and expensive.
This blog offers guidance for stormproofing your property, understanding local drainage risks, and knowing when to call in expert help for flood recovery and prevention.
Why Summer Storms Are a Bigger Threat Than You Think
Salt Lake City’s dry climate often creates a false sense of security, but July storms can dump multiple inches of rain in under an hour, overwhelming even well-designed drainage systems. The danger lies in how the water flows:
- Dry, compact soil can’t absorb water fast enough, leading to rapid runoff
- Sloped lots funnel rainwater directly toward homes and garages
- Gutters clogged with spring debris send water cascading over the roofline
- Street-level drains can back up, forcing water back toward properties
In flood-prone areas near creeks or canals, the risk is even greater. And because Salt Lake doesn’t see regular summer storms, many homes lack the moisture controls common in wetter climates.
Storm Prep Essentials for Salt Lake Homeowners
You don’t have to wait for a forecast to prepare. These simple actions can dramatically reduce the risk of storm-related water damage:
- Clean gutters and downspouts so rain flows away from your foundation
- Extend downspouts at least 4–6 feet from your home’s base
- Grade your soil so water slopes away from your structure
- Install window well covers to block water from basement egress points
- Test your sump pump and battery backup system
- Secure yard drains and clear nearby storm grates before a storm hits
Even if you live on higher ground, heavy rains can still cause roof leaks, clogged scuppers, or overwhelmed French drains. Don’t assume elevation alone will protect you.
Signs Your Drainage System Might Be Failing
Salt Lake’s clay-rich soils hold water differently than sandy or loamy types, which means water may sit around your foundation for hours before seeping in. Watch for these signs:
- Pooling water near the foundation after a storm
- Moisture or staining on basement walls
- Earthworms or insects appearing indoors post-rain
- Musty smells or humidity in crawl spaces
- Mold growth around baseboards or on stored items
These are early indicators of a drainage issue that needs attention—before the next storm hits.
What to Do During and After a Flash Flood
If a sudden downpour leads to interior flooding, your response time is critical. Here’s what to do:
- Turn off electricity to the affected area, if safe to do so
- Avoid standing water, especially if appliances or wiring are nearby
- Document the damage with photos for insurance
- Call a restoration team immediately—the first 24 hours are vital to preventing mold and structural loss
