Materials Accepted vs. Not Accepted

Accepted: Limbs, branches, woody debris, tree bark, pine cones, logs (max length 8 ft, max diameter 6 inches)
Not Accepted: construction material, lumber, household trash, metal of any kind, rocks, tree stumps, yard waste/grass clippings, bags, leaves

The majority of the materials that are not accepted often cause damage to our heavy machinery. Construction material and lumber typically have metal hidden throughout, which can cause damage to our grinder. Tree stumps often have rocks, which are challenging and time consuming to remove. We also do not accept leaves since other debris, such as rocks and metal, can get swept up with the leaves.

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: six yards is one load. The cost to drop off a single load is $24. Credit cards only. This is equivalent to:

• Truck bed full to truck cab height
• Trailer up to eight feet long by five feet wide by four feet high
• Loads outside these parameters will be charged accordingly

Calculate Cost

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

• A 16 foot long trailer that is five feet wide and stacked four feet tall with tree branches
• 16 feet by 5 feet by 4 feet equals 320 cubic feet
• 320 cubic feet divided by 162 cubic feet (six 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.
