Basement & Slab Water Intrusion Risk in Salt Lake City, UT

What this means if you live in Salt Lake City: FEMA rates your county's riverine flood risk as Relatively Moderate — among the lowest we track (#19 of 20). Flood pressure here is on the lower end of the metros we track, so water intrusion is a smaller driver of foundation problems than soil movement is — but "lower" isn't "none." Poor grading that pools water against the foundation, a downspout dumping right at the wall, or a clogged gutter can still push water in during a hard rain, so drainage and grading are the practical basics worth checking even here.

Flood risk: FEMA National Risk Index, riverine flooding, Salt Lake County level. This is a county composite that reflects area-wide flood exposure (including how many people and buildings are exposed), not a determination for your specific lot — look up your exact address on FEMA's Flood Map Service Center (msc.fema.gov) for your property's actual flood zone, and get a local inspection for how water actually moves on your site. Rankings are computed across the metros ClearPick tracks.

Water intrusion and soil movement are two different foundation threats — see also drought & freeze-thaw risk for the dry/cold side of what moves a foundation here.
