Colorado Fire Mitigation Guidelines for Creating Defensible Space

THE HOGBACK

A Grass and Oak Ramp Aimed at the Suburbs

The Dakota hogback runs like a wall along Littleton's western edge, and its east face is a fuel ramp: cured grass at the bottom, oak and mahogany brush through the middle, wind pouring over the top. Ken Caryl valley sits behind it. Deer Creek's neighborhoods press against its base. South Valley open space threads between them, beautiful and burnable. A fire starting anywhere on that face runs uphill fast and throws embers over the ridge into streets that feel nothing like wildland.

Marshall showed everyone what wind-driven grass and brush do when they reach a suburb. The hogback communities have the same recipe stacked against a steeper slope. That's the honest context for every mitigation decision in this part of the metro.

There's history in this corner of the county, too. The hogback and the canyons behind it have burned before, and Deer Creek Canyon's slopes carry old scars most residents drive past without noticing. The fuels grew back. They always do. What's different now is how many homes stand in the path, and how many were built assuming someone else had the fire problem handled.

GUIDELINES

What the State Model Actually Asks For

Colorado's guidance divides your land into three rings. Inside 30 feet, remove nearly everything that burns, keep grass short, and limb the trees so nothing carries fire from ground to crown. From 30 to 100 feet, thin and separate: about 10 feet between tree crowns, shrubs broken into islands, dead material out. Past 100 feet, manage for forest health. Slope stretches every one of those numbers, because fire moves uphill with the throttle open.

Those distances assume you own the land they describe. In Littleton, mostly, you don't. And that's where reading the guidelines stops and applying them starts.

Jefferson County and the local fire districts publish their own versions of this guidance, and they agree on fundamentals while differing on detail. When a district standard applies to your address, we cut to it. When none does, the state model is the floor we build from.

SMALL LOTS

When the Property Line Cuts Zone 1 in Half

On a typical Ken Caryl or Deer Creek lot, the back fence sits 25 to 40 feet from the house. Your entire legal jurisdiction is Zone 1. So we treat it with Zone 1 seriousness: every shrub choice matters, every tree gets limbed, the fence line gets stripped of the oak that leans in from open space, and the strip along the back becomes the cleanest ground on the property. What you can't control in distance you make up in intensity.

Then work the seams. HOAs and open-space districts in these foothill communities do run fuel projects, and a homeowner who shows up with a cleaned lot and a specific request gets taken seriously. The best mitigation here is layered: your 30 feet done right, the association's buffer behind it. We've cut both sides of that fence, sometimes in the same week.

Mastication isn't only for 40-acre parcels. The machine is compact, tracked, and precise enough to work a suburban backlot without touching the fence, the sprinkler heads, or the neighbor's aspen. Oak clumps grind down in minutes. The chips stay as a tidy mulch layer that suppresses the resprout, which matters because hogback oak comes back from the roots every time it's cut. Details on that fuel are on our brush clearing page.

For the tightest corners we finish by hand. The result reads as landscaping, not land clearing, which keeps both the HOA and the neighbors happy.

EMBER REACH

Streets Away From the Hogback Still Catch the Fallout

The hardest lesson from Marshall was how deep into the suburbs the fire reached. Homes ignited blocks from any open space, lit by embers and by fire passing house to house along wooden fences, junipers, and mulch beds. Distance from the hogback helps, but it doesn't excuse a lot from the ember conversation. If wind can carry ash to your patio, it can carry ignition to your gutters.

For the interior streets of Ken Caryl and Deer Creek, mitigation looks less like land clearing and more like subtraction: the juniper hedge against the siding, the wooden fence section that ties your house to the neighbor's, the needle-filled gutters, the shrub bed under the bay window. Small fuels, close to structures, connected in a line. A wind-driven ember storm finds every one of them in order.

We handle the vegetation side of that list in a day for most lots, and we'll point out the non-vegetation items while we're there. Pair the cleared lot with hardened details, vents, gutters, fence-to-wall connections, and an interior-street home becomes a genuinely hard target. That combination, repeated down a block, is how a street survives what a single perfect lot can't.

A Half Hour on Your Back Fence Line

Every hogback-edge property has one or two decisions that matter far more than the rest, and you can't find them in a pamphlet. We can find them standing in your yard in about thirty minutes. You'll get a written price, an honest opinion about what's worth doing, and zero pressure about the rest.
