PIONEER SAND & GRAVEL – www.pioneersand.com sites in Arvada, Broomfield, Boulder, Aurora, Golden, Littleton, Brighton and Northglenn accept SLASH.
JEFFERSON COUNTY – jeffco.us/slash – In 2015, Jefferson County expanded their slash collection program through events throughout the summer. Check their website for scheduled dates and times.
If none of the above mentioned options fit your need consider renting wood chippers to eliminate slash and use the mulch created for landscaping purposes.
