This project required a new private vehicular access driveway and bridge over Left Hand Creek on a former golf course called Haystack Ranch. DBC provided roadway design for the driveway with structural support from Centennial Engineering for the bridge design. DBC completed internal hydraulic modeling for the bridge. The project required Boulder County development review, a floodplain development permit, and a FEMA CLOMR. The project construction was completed in early 2026, and we are currently working on the follow-up LOMR.
