Where to Dump Dirt in Berthoud, CO

Last updated August 20, 2026

Berthoud sits about 19 miles south of Fort Collins, in Larimer County — contractors here get matched with the closest approved free site instead of driving to a landfill. Members dump for free at approved sites; your first load is free even if you never sign up.

Berthoud sits in Larimer County — the same CDPHE inert-material rules apply here as anywhere else in the Northern Front Range foothills.

Local ground conditions

Fort Collins sits where the Front Range foothills meet the Cache la Poudre and Big Thompson river valleys — a mix of foothills-influenced soil and sandy river-alluvial deposits, generally less uniformly expansive than the Denver Formation claystone found closer to Denver.

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
