Expert Potholing Services in Marin County
By Devco Development & Engineering
Devco Development & Engineering provides professional Potholing (utility daylighting) services in Marin County, California. We use precision hydro excavation to safely expose underground utilities and confirm their exact location and depth before construction begins. With our California Class A (General Engineering) and Class B (General Building) contractor licenses, we support projects in developed corridors and environmentally sensitive areas with a safety-first approach.
In Marin County, minimizing surface disturbance and protecting surrounding improvements is often a top priority. Potholing reduces uncertainty by verifying utility depth and alignment at crossings and conflict points—helping avoid strikes, prevent delays, and support accurate planning for trenching or HDD.
Devco is a proud Disabled Veteran Business Enterprise (DVBE) and holds additional certifications including SDVOSB, PDBE, SB-Micro, and SB-PW.
