A round of updated federal flood maps becomes official in Provo and across Utah County on June 23, 2026 — and for some property owners, it changes the picture of whether their home sits in a mapped flood zone.
The maps in question are FEMA's Flood Insurance Rate Maps, or FIRMs. They're the official documents that mortgage lenders and insurers use to decide which properties carry the highest flood risk and, in turn, which homeowners are required to carry flood insurance. Utah County, Provo, Orem, and other Utah Lake-area communities worked with FEMA and the state to redraw these maps to reflect current conditions along the Provo River and the Utah Lake shoreline.
Why the maps are changing
Flood maps aren't static. They get periodically updated because the underlying risk shifts — from weather patterns and erosion to new development and channel changes like the major Provo River Delta restoration on the west side of town. The goal is to give residents and the city a more accurate read on where water is likely to go in a serious flood, which remains one of Utah's most common and costly natural disasters.
For most of the valley, the practical effect is small. But a subset of properties — particularly those nearer the river corridor and the lakeshore — may find themselves newly inside, or newly outside, a mapped Special Flood Hazard Area.
What to do before June 23
The single most useful step is to look up your own address. FEMA's Flood Map Service Center (msc.fema.gov) lets you search any property for free, view the effective map, and download a printable map panel for your parcel. If you're unsure how to read it, Provo's floodplain administrator works directly with FEMA on these maps and can help you interpret your zone.
A few things worth knowing:
- If you have a mortgage and your home moves into a high-risk zone, your lender will typically require flood insurance once the new maps are effective.
- Timing can matter. When a property is shifting from lower to higher risk, buying or renewing a policy before the new map takes effect can sometimes secure a "grandfathered" rate based on the current, lower-risk designation.
- Standard homeowners and renters insurance does not cover flooding. Flood coverage is a separate policy, usually through the National Flood Insurance Program.
Why it's worth a look even if you rent
Renters can't be required to insure the building, but flood policies for personal belongings exist and are worth considering if you're in a newly mapped area near the river. And if you're house-hunting in Provo this summer, the new maps are a smart thing to check before you make an offer — flood-zone status affects both insurance costs and long-term resale.
