• Slash Collection


    Got Slash? We Provide Plenty of Opportunity to Dispose of it!

    Clear your property and bring your tree debris to the Jefferson County Slash Collection! We'll be somewhere in Jefferson County every weekend from May 20-Nov. 12.

    Slash is debris, from nature, such as tree limbs, prunings and pine needles. If not removed, slash can add to potential fire hazards on your property. The importance of mitigating and preparing your property for wildfire cannot be understated - and again this year, Jefferson County is your partner in this effort.

  • The Importance of Mitigation

    Removing slash and creating a defensible space around your home, is the first line of defense against wildfires. You can create zones around your home, removing any fire fuels, such as tree debris. Having a properly mitigated property doesn't mean that wildfire will pass you by, but it gives the fire department a better opportunity to save your home when it does come. Great tips on how to protect your home and property can be found on the Jeffco Sheriff’s hazard mitigation page and at www.firewise.org.

    Fees for Slash Drop-off

    Any size truck or trailer is welcome at Jefferson County Slash Collection sites. Dump fees are based on six cubic yards (162 cubic feet) of material: 6 yards = 1 load. The cost to drop off a single "load" is $20. Credit cards only.

    This is equivalent to:

    • Truck bed full to truck cab height
    • Trailer up to 8' l x 5' w x 4' h
    • Loads outside these parameters will be charged accordingly


    Here is an example to know how to figure your cost:

    • A 16-foot-long trailer that is 5-feet wide and stacked 4-feet tall with tree branches
    • 16 feet x 5 feet x 4 feet = 320 cubic feet
    • 320 cubic feet divided by 162 cubic feet (6 yards) = 1.98 "loads"
    • Each load is $20
    • So, rounded off, this example trailer will cost $40 to drop at a Jeffco Slash Collection site


    The fees that are charged help to offset the cost for the processing equipment, staffing and keeping the program sustainable so it can continue into future years.

    Slash Collection Program Background

    Jefferson County began expanding its slash program in 2014 when the Board of County Commissioners approved the expansion of the program within the budget and moved forward with an expanded slash collection program beginning in 2015.

    In past years, the Sheriff’s Office operated the county slash collections; however, more sites were needed to accommodate the demand. This expanded program provides a more robust, long-term solution to assist in fire mitigation throughout Jeffco.
