Underground Utilities
We install water mains, sanitary sewer, storm sewer and power and communications conduit for subdivisions and commercial sites. Each run goes from open trench to compacted backfill, ready for the inspector.

The federal soil survey maps much of west Eugene as Natroy: a thin silty layer over heavy, poorly drained clay. From November to May, its water table runs from a foot above the ground to a foot below it. The clay cracks open each summer and closes again when the rain returns. A street or a sewer trench in that ground needs a drainage plan before the first load of rock.
Turner Excavation is an excavation contractor for builders and developers, and Eugene is part of our service area. Next door in Springfield, the company has built a new water distribution system and a sanitary sewer line. Here we take on underground utilities and subdivision development, from raw ground to finished lots. Call or text (503) 507-2919 to talk through a Eugene project.

Eugene's soil changes from one side of town to the other. In River Road and Santa Clara, the most common soil on the same survey is Malabon silty clay loam. It drains well, and Bethel's most common soil, Coburg silty clay loam, is rated moderately well drained. Along the Willamette River and Amazon Creek, some parcels sit in a FEMA flood zone or floodway.
The Southwest Hills are steeper ground. Dixonville silty clay loam is the most common soil there, mapped on slopes up to 50 percent. Any parcel steeper than 10 percent counts as a sensitive area under the city's erosion rules. On slopes like those, our grading and earthwork follows the engineer's plan, with erosion control in before the first cut.
NOAA's 1991 to 2020 normals put the Eugene airport at about 41 inches of rain a year. About nine-tenths falls from October through May, and July and August average under half an inch each. The city's erosion program sets a wet weather season from October 15 to April 30. On ground this wet, plan the storm drainage and French drains before the pads and streets.
Eugene counted 176,654 people in the 2020 Census, and the Census Bureau estimated 178,618 for 2025. About half of the city's housing units were built before 1980, and about a quarter in 2000 or later. On older parcels, new construction often starts with removing old slabs and buried service lines.
The Census Bureau's permit survey counts about 1,000 new housing units permitted in 2024 and about 850 in 2025. About two-thirds were in buildings of five units or more, the kind of site that starts with commercial site work. Oregon's housing needs analysis sets a target of 1,676 units a year inside Eugene's urban growth boundary. That is about twice the 2025 permit count.
Large parts of River Road and Santa Clara still sit outside city limits. On a parcel there, the first question is city or county, because that sets the permit office. City records list more than 100 annexations from 2015 on, most of them in those two areas. In 2024 and 2025, larger blocks on the northwest and west edges joined the city too.
Inside city limits, permits run through Building and Permit Services in the city's Planning and Development Department. Its counter is the Permit and Information Center downtown. Rural parcels outside the urban growth boundary go to Lane County's Land Management Division for building permits and land use.
Public streets, sewer mains, storm lines and street lights that a developer's engineer designs go through the city's PEPI process. PEPI stands for Privately Engineered Public Improvement, and Public Works inspects the work during construction. For a PEPI street, our work covers the excavation, subgrade, base rock and pipe underneath. Curbs and asphalt go in through the paving and concrete subcontractors we manage.
EWEB, a customer-owned public utility, provides electric and water service in the Eugene area. Its water comes from one source, the McKenzie River. On dry utility work, we coordinate conduit and vaults with the utility and the inspectors.

(503) 507-2919 We install water mains, sanitary sewer, storm sewer and power and communications conduit for subdivisions and commercial sites. Each run goes from open trench to compacted backfill, ready for the inspector.

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.
Learn More
We clear and grade commercial sites, build the pad and run the utilities to the building. We bring the parking lot to base rock, and our paving and concrete subcontractors finish it.

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.

Mass grading and cut and fill for subdivisions, commercial sites, farms and nurseries. We move the soil to the grades on the plan and compact the fill in layers.

Trenching for water lines, power conduit and drain lines across acreage and commercial sites. Every run starts with an Oregon 811 locate request and ends in compacted backfill.

French drains, curtain drains, catch basins and culverts for building sites, subdivisions, farms and nurseries. We build each system on a steady fall to an outlet, to the engineer's plan where there is one.

We build subdivision streets and private roads from the subgrade up, with the utilities under them laid first. Our concrete and paving subcontractors pour the curbs and lay the asphalt, under our management.
Learn More
Long gravel driveways, farm and nursery access roads, equipment yards and construction entrances for builders and landowners. We grade the road and set the culverts, then build up the base rock to carry trucks.
Learn More
We handle foundation excavation and build compacted building pads for homes on acreage, shops, barns and commercial buildings. Footings are cut to the engineer's plan, and every pad is graded to drain.

Directional drilling carries water services and power and communications conduit under roads, paved drives, parking lots and creeks. The pipe pulls back through the bore, and the surface above it stays in place.

We take down old structures and break out the concrete and asphalt under them. Our dump trucks haul the debris off, and we grade the site for the next build.
