Glendale’s biggest natural hazard is avalanches
Most of the natural-hazard damage FEMA expects in Glendale comes from avalanches, and overall the risk is very high for a U.S. community.

What Glendale faces
Each hazard’s share of the damage FEMA expects here, and how it compares with the rest of the country.
Avalanches
Wildfire
Inland flooding
Does Glendale flood? No paid flood claims on record
FEMA’s records show no paid flood insurance claims in Glendale. That’s not a promise: most homes don’t carry flood insurance, so small floods go unrecorded.
Glendale isn’t in FEMA’s Community Rating System, which cuts flood insurance up to 45% in towns that do extra flood-proofing.
Insurance rates: Boulder County.How exposed is Glendale?
FEMA expects yearly storm and flood damage to homes and buildings here to be higher than in 98% of U.S. communities, mostly from avalanches and wildfires.
Rated higher than 478 of the 481 Colorado towns we cover.
Glendale is smaller than a census tract, so it shares the figures of the tract around its center.
Federal disasters declared here
None of the disasters declared for Boulder County shows FEMA aid or repair money reaching Glendale itself in FEMA’s records.
Boulder County has had 15 natural disasters declared since 1953, most often fires and floods.
Get ready for what Glendale actually faces
A short kit for its top hazards, what to check before you buy, and where neighbors get alerts.
- Check the avalanche forecast before heading into the backcountry.
- Carry a beacon, probe and shovel, and know how to use them.
- Most avalanches are set off by the people caught in them.
- Clear dead leaves and brush within 5 feet of the house.
- Sign up for local alerts and know two ways out.
- Keep N95 masks for smoky days.
- Turn around at flooded roads: a foot of moving water can carry off a car.
- Flood insurance usually takes 30 days to start, so buy it before the forecast.
- Keep papers and medicines up high, in a grab-and-go bag.
- Look up the address on FEMA’s flood map.
- Ask the seller or landlord whether it has ever flooded, and what flood insurance costs there.
- Get a flood insurance quote early: policies usually start 30 days after you buy.

|---|---|---|---|

Rating = expected yearly storm and flood damage as a share of what’s there, vs. U.S. communities. Flood claims = paid federal flood insurance claims on record.
Disasters here can come any time of year
The month each of Boulder County’s 15 declared disasters began, since 1953.
What these numbers can and can’t tell you
- An average, not a forecast. FEMA’s National Risk Index estimates the damage 18 kinds of natural hazards cause in a typical year, from decades of records and models. A quiet decade can follow a bad year.
- Compared by rate. “Higher than N%” compares yearly damage as a share of what’s there, so a big city isn’t rated riskier just for having more buildings.
- Money that reached town. Flood claims are matched to Glendale’s own flood-insurance community; household aid to the registrant’s city; repair grants to Glendale.
- It follows property value. FEMA’s model weighs damage to buildings, so a place that recently lost many homes can rate lower than it feels.
