Straight talk
Why this page exists
This valley lives with its river — the beauty and the risk are the same water. The July 2025 floods changed how everyone here talks about riverfront property, and honestly, for the better: buyers ask harder questions, and well-documented properties stand out. Only a small fraction of the Kerr County homes damaged in 2025 carried flood insurance. That's the gap this page is here to close — matter-of-factly, without either sales gloss or scare tactics.
Read the map first
Every parcel near water has a FEMA designation. The short version:
- Floodway — the river's active channel during flood. Building is heavily restricted; treat structures here with maximum skepticism.
- Zone AE — the mapped 1%-annual-chance ("100-year") floodplain, with base flood elevations set. Insurable, buildable with rules, priced accordingly.
- Zone A — same risk class, but no modeled elevations — you'll want a surveyor's help.
- Zone X — outside the mapped high-risk area. Lower risk, not zero risk; 2025 taught everyone that water doesn't read maps.
Look up any address at FEMA's Flood Map Service Center. Remember maps are periodically re-drawn — and post-2025 revisions are worth watching.
Kerr County flood map: how to look up any property
- Go to FEMA's Flood Map Service Center and enter the address — the map viewer shows the parcel's zone (AE, A, X, or floodway).
- Cross-check the parcel on Kerr CAD (Gillespie or Kendall CAD for Harper/Comfort) to confirm boundaries and improvements.
- For anything zoned AE/A or close to it, get the elevation certificate conversation going early — it's the difference between the parcel's zone and the structure's actual risk.
- Remember maps get re-drawn — post-2025 revisions are in motion, so verify the map's effective date and ask the county floodplain administrator about pending changes.
Does Kerrville flood often? The honest answer
The Hill Country is flash-flood alley — thin soil over limestone, steep drainages, and storms that park over the headwaters. The Guadalupe saw major floods in July 2025 and again in July 2026. And yet: flood risk here is property-specific, not town-wide. Most Kerrville-area homes sit well above and outside the floodplain and have never taken water; river-adjacent parcels are a different conversation entirely. So the honest answer is: the river floods; the towns mostly don't; the right question is about the specific parcel — which is exactly what the lookup steps above and the checklist below answer.

Flood insurance in Kerr County
Before 2025, only about 2–3% of Kerr County homes carried flood insurance — and standard homeowner policies exclude flood damage entirely. If you're buying anywhere near the river:
- Get a real quote during your option period — NFIP via FloodSmart plus at least one private-market quote; prices vary more than people expect.
- An elevation certificate can significantly lower the premium for a well-sited structure — often paying for itself in year one.
- In mapped high-risk zones with a federally backed mortgage, coverage isn't optional — it's required. Budget for it in your offer math, not after.
- Outside mapped zones, cheap preferred-risk policies exist — 2025 flooded plenty of "Zone X" properties, and the owners with those policies recovered fastest.
The questions we ask on every river property
- Where does the structure sit relative to the base flood elevation — not just the lot? (This is what an elevation certificate answers.)
- What's the property's 2025 story? What flooded, what didn't, what was repaired, with what documentation?
- What does a real flood insurance quote come to — NFIP and private? Get the number before you're emotionally committed.
- How's the access? A dry house behind a low-water crossing still floods you out of getting home.
- What are the county's floodplain development rules for any addition, barn, or RV pad you're dreaming about?
Owning riverfront responsibly
Locals who love this river follow the same playbook: flood insurance even when optional, weather radios and county alerts on, valuables and vehicles staged high when the forecast turns, and total respect for rising water. The live river page shows the gauges everyone here watches. None of this diminishes river life — it's what lets you enjoy it for decades.
