# Animas Excavating > Licensed and insured excavation contractor based in Durango, Colorado, serving residential, commercial, and municipal clients throughout the Four Corners region of Southwest Colorado. Animas Excavating LLC was founded in 2018 by Mike Zarlingo and specializes in full infrastructure installation on raw land, site preparation, underground utilities, sewer line repair, septic systems, demolition, retaining walls, and road construction. The company operates across Durango, Bayfield, Hesperus, Mancos, Cortez, Pagosa Springs, and the broader Four Corners region. It is a certified OWTS installer listed on the La Plata County Public Health roster, fully insured and bonded, and registered as an FMCSA carrier (USDOT 3961462).
