Where to Dump Dirt in Commerce City, CO

Commerce City’s industrial and residential mix keeps a range of crews moving dirt — matched with an approved site by your dispatcher, not a guess. Members dump for free at approved sites; your first load is free even if you never sign up.

Commerce City sits in Adams County — the same CDPHE inert-material rules apply here as anywhere else in the Front Range / Denver Basin.

Local ground conditions

Front Range excavation regularly hits Denver Formation and Pierre Shale claystone — bentonitic, expansive clay with real swell potential, made more complicated by freeze-thaw cycles through the winter grading season. Getting that material off-site fast matters more here than almost anywhere else, since a stalled pile can turn into a frozen, unworkable one.

How verification actually works

Neither CDPHE (Colorado Department of Public Health & Environment) nor any other state agency issues a formal “certified clean fill” seal — that term doesn’t exist in the regulatory language (6 CCR 1007-2 and equivalent). What actually happens at every approved site in our network:

• A published acceptance policy — exactly what’s in, exactly what’s out (no trash, no C&D debris, no treated wood, no contamination)
• The right to inspect and refuse any load at the gate
• A load ticket logged for every delivery, so there’s a real record if a question ever comes up
