If you own a mountain rental in Colorado, you’ve spent the last few summers worrying about wildfire. Fair enough — it’s the obvious threat. But right now, this week, the danger to a lot of properties isn’t fire at all. It’s what the fire left behind.
On Sunday, August 17, an 80-year-old man was swept away and killed by flash floodwaters in Beulah, near the intersection of Colorado 78 and Central Avenue. The water came off the 102,000-acre Aspen Acres burn scar, the same fire that destroyed more than 300 homes earlier this summer. It took just an inch and a half of rain in ninety minutes to turn a creek into something that could kill a person. Three days later, on Wednesday, it happened again — flash flooding tore through the same area, washing out County Road 378 and forcing a temporary closure of Highway 165 near Lake Isabel. And 150 miles north, the Cameron Peak burn scar in Larimer County has triggered its own string of flash flood warnings this summer, with the National Weather Service calling conditions in parts of the county “life-threatening.”
Here’s the part most hosts don’t clock: you don’t have to own a burned property to be exposed. If your rental sits downhill, downstream, or even just downwind of a recent burn scar, you’re in the blast radius of every storm that hits that scar for years to come — regardless of whether a single tree on your own lot ever caught fire.
Why a fire from last year is still flooding people out today
A healthy mountainside works like a sponge. Trees, roots, and duff soak up rain and slow it down on its way downhill. A wildfire strips all of that away in a matter of hours, and it can take years for it to grow back. In the meantime, the scorched soil sheds water almost like pavement — the National Weather Service puts it plainly: burn scars are “particularly vulnerable to flooding because wildfires strip away vegetation and leave soil unable to absorb heavy rain.” A storm that would have been a non-event two years ago now sends a wall of water, mud, and debris straight down the drainage — and that drainage doesn’t stop at the edge of the burned acreage. It keeps going, through culverts, across roads, and directly at whatever’s sitting downstream. Including, potentially, your guests.
This is why the Aspen Acres and Cameron Peak burn scars are still generating warnings and closures a year or more after their fires were declared out, and why forecasters are watching this exact pattern repeat across Colorado’s monsoon season right now.
What this actually means for your rental
- A “safe” property can still get cut off. Even if your cabin sits well outside any burn scar, the access road to it might not. Highway 165 and County Road 378 both saw closures this week — guests (or you) can get stranded, and delivery, maintenance, or emergency vehicles can’t always get through either.
- Debris flow moves fast and without much warning. The Beulah flood went from a flood watch to a fatality in the same afternoon, on just 1–1.5 inches of rain. If you’re relying on “it’s not raining that hard” as your safety check, that’s not enough anymore near a burn scar.
- Insurance and guest-safety exposure compound. A washed-out culvert, a flooded crawlspace, or a stranded guest during a debris flow isn’t just a cleanup problem — it’s a liability conversation you don’t want to be having for the first time after the fact.
- This isn’t a one-summer problem. Burn scars typically carry elevated flood risk for three to five years after a fire, sometimes longer at higher elevations. If a fire burned anywhere upslope of your property in the last few years, this is now a standing part of your risk profile, every monsoon season, not just this one.
What to actually do about it
Check whether any wildfire in the last several years touched terrain above or upstream of your property — not just on your own lot. The National Weather Service’s burn scar flood potential page (weather.gov/bou) tracks active burn scar flood risk for the region and is worth bookmarking if you host anywhere in the foothills or mountains. During active monsoon weeks, keep an eye on flash flood watches and warnings the same way you’d watch a wildfire evacuation zone — and make sure your guests know what a flash flood warning means and where higher ground is, the same way you’d brief them on a fire evacuation route.
And if a storm does come through — mud, silt, and debris in a crawlspace, garage, or entryway isn’t something a standard turnover clean is built for. That’s exactly the kind of job we get called for after a flash flood event, and it’s worth having a plan for before you need one rather than during a scramble between guest stays.
