Subdivision Development
We turn raw land into finished, buildable lots for builders and developers. Every underground utility goes in before the streets, and each lot is left graded for its builder.

Turner Excavation is an underground utilities contractor for builders and developers around Dallas, Oregon. We install the wet utilities: water mains and services, sanitary sewer and storm sewer. We also lay the dry utilities, the conduit and vaults that carry power and communications. Underground utility installation is one part of our work as an excavation contractor in Dallas, OR.
On a subdivision development, the utilities go in before the streets and the lots. In Dallas, we laid the sewer and water lines for future lots, along with their storm pipe. Commercial property owners and water cooperatives hire us for the same work. We work from our yard in Dallas, with Polk and Marion Counties at the core of our range.

Water line installation runs from the main to each meter, and Oregon's drinking water rules shape the work. They call for at least 30 inches of cover over distribution pipe. The pipe sits fully supported in bedding kept clear of rocks. Select backfill gets tamped in layers around and over it.
The same rules call for a copper tracer wire with blue insulation on plastic water pipe. That wire lets a locator find the line later. Hydrants and tees get restraint, so the fittings stay put when the line is under pressure. Fire hydrants go where the approved plans place them.
Most sanitary sewer runs on gravity, so we lay mains and laterals to the grade on the engineer's plan. At a crossing, the rules want the water line's bottom 1.5 feet or more above the sewer, where possible. Storm sewer goes in on the same schedule. Catch basins and outfalls are part of our storm drainage work.
Dry utilities carry power and communications through conduit. We lay the conduit runs and set the vaults and pull boxes to the serving utility's plan. The utility or a licensed electrician pulls the wire and makes the energized connections.
Each utility sets its own specs for conduit depth and vault spots. We build to those specs and the approved plans, then backfill and compact over the run. Under a road or a creek, directional drilling can carry a line without an open cut.
Every dig starts with an Oregon 811 locate request, made at least two full business days ahead. Then the trench opens to the depth on the plan, and the pipe goes in on its bedding.
Backfill goes back in lifts, and each lift is compacted before the next one. Under a future street, that compacted trench supports the base rock and the paving above it. Long service runs across farm and nursery ground fall under our utility trenching work.
The jurisdiction's inspectors check each stage at the points their standards set. We plan the trench schedule around those visits and the utility's own checks.

Call or text (503) 507-2919 and tell us about the land and the project. Plans or a site map help if you have them.
We come out to look at the ground and where the water goes. If there are plans, we go through the quantities with you.
The free estimate comes to you in writing, with the scope of work spelled out. Once you say yes, we set the start date together.
We call Oregon 811 for utility locates before any digging. Then the work goes in the order the job needs, from clearing through base rock.
We work with the city or county inspectors as the utilities go in. We leave the site graded and ready for the builders or the next trade.

Excavator land clearing for building sites and development parcels, with the stumps and roots pulled out. We strip and stockpile the topsoil, then rough grade the ground for the next stage.
Learn MoreWe put in the water, sewer, storm and dry utilities, then build the street over them. Our paving and concrete subcontractors finish the curbs and asphalt under our management.
Our excavators, dozer, water truck and dump trucks do the heavy work. Our crew and foreman run the site from the first cut to final grade.
We look at the plans and the ground before we price the work. Then the free estimate comes to you in writing, with the scope spelled out.
Our shop and yard are in Dallas, in Polk County. We take on projects about 70 miles out, across the Willamette Valley and over the Coast Range to Newport.
