Protecting Rainbow Hill, Together

Welcome to Rainbow Hill

Rainbow Hill is more than a neighborhood, it’s a community built on connection, stewardship, and looking out for one another. This website serves as a central resource for residents to stay informed about neighborhood news, community projects, wildfire preparedness efforts, events, and ways to get involved. From protecting our forests and homes to supporting our neighbors during emergencies, we believe a stronger community is built when everyone plays a role. Together, we can preserve the beauty of Rainbow Hill while creating a safer, more connected future for everyone who calls it home.
A HUGE thank you to Eric & Kelby with Clear Creek Watershed & Forest Health Partnership (CCWFHP) and Jefferson County Sherriff’s Office (JCSO) Wildland Fire crews for helping to remove over 650 piles of slash fuel from our hill!

Eric and Kelby continue to advocate for our hill - stay tuned for additional news and updates!

MPB Landowner Assistance

2026 Mountain Pine Beetle Landowner Assistance Program
Jefferson County is providing a cost-share opportunity for landowners to help control mountain pine beetle (Dendroctonus ponderosae) (MPB) on privately owned lands within Jefferson County. The funding for this pilot program is being made available for removal and of green pine trees infested with live mountain pine beetle including treating by solar, debarking, chipping, or mastication. Trees that died in prior seasons are not eligible.

Defensible space around the home - zone 1 is 0-5', zone 2 is 5-30' and zone 3 is 30-100'

Colorado State Forest Service Fire Mitigation Guidelines

IMMEDIATE ZONE (0-5 feet)- Non combustible area
This is the most important zone to take immediate action as it has the greatest vulnerability to wildfire embers.
  • Remove ALL flammable material within 5 feet of structures
  • Clean roofs and gutters of pine needles and debris that could catch embers
  • Replace or repair any loose or missing shingles to prevent ember penetration
  • Clean debris from exterior attic vents and install 1/8th inch metal screens to reduce ember intrusion
  • Repair or replace damaged or loose window screens and enclose under patio/deck areas wire mesh to prevent debris and combustible materials from accumulating
  • Move any flammable material away from wall exteriors (mulch, flammable plants, leaves and needles, firewood piles)

INTERMEDIATE ZONE (5-30 feet)
Landscaping/Hardscaping- Employ careful landscaping and create breaks that can influence and decrease wildfire behavior
  • Clear vegetation under large, stationary propane tanks
  • Create fuel breaks with driveways, walkways/paths, patios, and decks
  • Mow grasses to 4 inches or less
  • Remove ladder fuels (vegetation under trees) so surface fires cannot reach the crowns
  • Prune trees up to 6 feet from the ground
  • Space tree crowns 15+ feet apart (more on steeper slopes)
  • Trees and shrubs in this zone should be limited to small clusters of a few each, to break up the continuity of the vegetation across the landscape

Pine trees with Verbenone packets attached

Verbenone Packets

Verbenone is not a conventional pesticide and is not toxic to animals or the environment. It is a registered product with EPA in the USA.

Verbenone is an antiaggregation pheromone for Mountain pine beetle (Dendroctonus ponderosae), Southern pine beetle (Dendroctonus frontalis), Western pine beetle (Dendroctonus brevicomis) and other bark beetles. Verbenone, as a stand alone product,  is normally only deployed to deter mass attack of Mountain Pine Beetle in tree stands. It has not been proven as a single pheromone deterrent for tree protection from Southern Pine Beetle, Western Pine Beetle, or Ips species.


How do I use verbenone?
Packets containing verbenone are stapled to the trunk of pine trees. The number of packets needed per tree depends on the diameter of the tree. The number of packets per acre depends on the density of the site. The packets are typically attached to the trunk on the north side of the tree, about 6 to 7 feet above the ground, and spaced on trees approximately 12 feet apart.


Will it protect my pine trees from mountain pine beetle?
Studies have shown varying success. The effectiveness will vary depending on many factors including weather, site conditions, forest density, and beetle population size. Verbenone may help disperse beetles but under heavy infestation conditions it may have a much-lowered effect. Other control methods—such as removing infested trees, thinning forests, or applying preventative insecticides—should also be considered. Our fact sheet outlines the available options in more detail.


What time of year would I use verbenone?
Packets need to be in place by mid-June, before the mountain pine beetles fly, and left in place until at least mid-September. Depending on a site’s condition and the specific product used, the verbenone may need to be reapplied mid-season.


Do I have to use verbenone?
No. Verbenone may be used as a part of an integrated pest management plan to help reduce mountain pine beetle activity on individual properties. It is a preventative option but does not control the beetles.

FFPD Hazard Zones By Rating

Rainbow Hill Road
The Issue

Rainbow Hill is currently rated Class 10 fire risk—the highest level possible per the Foothills Fire Protection District Community Wildfire Protection Plan, December 2020 report.

This is why many of us are losing homeowners insurance or facing skyrocketing premiums. According to the Colorado State Forest Service (CSFS), the only way forward is clear: we must create defensible space around our properties and establish shaded fuel breaks across the hill.

By addressing these priorities, we not only reduce wildfire danger but also improve the overall health of our forest, limiting the spread of pests like pine beetles.

If you are interested in having your land included in this protection plan, you MUST mark yourself "confirmed" on the community spreadsheet. Only committed residents property will be included in the plan. This is not a commitment—it simply ensures you’re included in the planning process and have a voice in the solution.

With community participation, we can transform our neighborhood from one of Colorado’s highest wildfire risks into a model for safety, resilience, and forest health.
