Many valley terrace soils in the Willamette Valley, including the Willamette soil series, typically feature silt loam surface layers over clay-enriched subsoil horizons. Evaluating soil conditions and drainage is standard practice in excavation planning. This is to avoid potential problems, such as settlement or water management issues, caused by poorly prepared or saturated ground.
Integra Built has operated in Salem, Bend, and the surrounding areas since 2010. We plan the excavation scope around what is actually in the ground, what the permit jurisdiction requires, and what the construction sequence demands. One contractor handles everything from start to finish.


Why Excavation in the Willamette Valley Is More Involved Than Just Moving Dirt
Salem soil shifts by season. Older neighborhoods hide undocumented utilities. Grading permits, Oregon 811 locates, and Marion County coordination all need to be lined up before equipment arrives. Four things shape every project we scope here:
- Oregon 811 locates (ORS 757.557): State law requires a locate request at least 2 business days before any digging. We file every request before equipment is scheduled.
- Willamette Valley clay soil: Many Willamette Valley subsoils contain clay-rich horizons, often in the 25–35% range depending on the soil series. It holds water and shifts with the seasons. We check soil conditions at scope, not mid-dig.
- Grading permits (City of Salem and Marion County LDEP): Significant grading within city limits needs a permit. Right-of-way work goes through Marion County. We schedule around review timelines.
- Central Oregon: separate jurisdiction: Bend and Deschutes County have different soil and separate permit timelines. We scope those projects independently.
Six Types of Residential Excavation We Handle

Site Prep and Pad Grading: The Starting Point for Most Builds
We strip topsoil, set rough grade, and compact the pad to spec. This is where additions, new homes, and detached garages begin. In older Salem neighborhoods, such as those near Commercial Street, tight lots dictate machine size. We check access and staging before scheduling anything.

Foundation Excavation: Reaching Bearing Soil the Right Way
Foundation digs must hit undisturbed native soil at the depth your engineer specifies. In the Willamette Valley, that is usually 12 to 24 inches down, but the lot history matters. We stage or remove spoil based on whether it can be reused as backfill. We coordinate with your foundation contractor on dimensions, stepped footings, and inspections.

Utility Trenching: Water, Sewer, Power, and Drain Lines
We dig below-grade trenches for water lines, sewer laterals, electrical conduit, and drain pipe. Depth and bedding follow the applicable utility code. Oregon 811 locates are filed before any trench opens. In Keizer, we plan sequences to limit open-cut time. Salem sewer tie-ins require city coordination on connection points.

Drainage Excavation: Fix Water Problems Before They Get Worse
Clay soil in Marion County does not drain on its own. Soggy lawns, wet crawl spaces, and pooling near foundations need below-grade solutions. We excavate for French drain systems, set perforated pipe in drain rock, and grade swales to direct flow. We define the scope after we know where the water comes from and where it needs to go.

Earthmoving and Regrading: Level Ground Where There Was None
Sloped lots, uneven driveway approaches, outdoor terracing, and disturbed post-construction sites all need regrading before work can start. We cut to design elevation and haul material that cannot stay on site. Fill brought in goes down in compacted lifts and gets verified before any load is applied.

Demolition Excavation: Below-Grade Removal Before New Construction
Old foundations, buried tanks, and below-grade structures need to come out before new work begins. We break out concrete and clear fill, leaving a clean bearing surface. In Salem’s older neighborhoods, mid-century subsurface conditions are often unrecorded. We work carefully and document what we find before deciding on the next steps.

Not Sure What Scope You Need? Here Are the Three Categories.
Most residential excavations fit into one of these:
- Site prep and finish grading: Topsoil off, rough grade set, pad compacted, final grade done. This is the starting point for additions, outbuildings, and new pads.
- Drainage and utility excavation: Targeted digging for French drains, sewer laterals, water lines, or conduit. Scope follows the utility spec and trench requirements.
- Foundation and structural excavation: Deeper work to reach bearing soil. Used for foundations, below-grade removals, and basements. Depth and dimensions come from the engineer.
We confirm the right category at the estimate stage, after a site visit. The scope is not signed off until we have checked soil conditions, site access, permit requirements, and the build sequence.

Codes and Permit Authorities That Apply to This Work
Excavation work in Oregon must comply with several state and local requirements before and during excavation. These rules govern utility locates, soil disturbance, drainage, and foundation preparation. The exact permits depend on project scope and jurisdiction. The references below list the codes and authorities most commonly applicable to residential excavation projects in Salem, the Willamette Valley, and Central Oregon.
| Code / Authority | What It Governs | Why It Matters for Excavation |
|---|---|---|
| ORS 757.557 (Oregon Dig Law) | Utility locate requirement | Excavators must notify Oregon 811 2–10 business days before digging so underground utilities can be located and marked. |
| Oregon Residential Specialty Code (ORSC) | Foundation excavation depth and bearing requirements | Governs minimum bearing depth and soil preparation for residential foundations across Oregon. |
| ORS 447.233 | ADA path-of-travel requirements | Applies when excavation is part of a larger permitted project — triggers review if project value exceeds 20% of assessed value. |
| Marion County LDEP / Salem Permit Application Center | Grading and excavation permits | Grading permits required for significant earth disturbance within Salem. LDEP governs county right-of-way and roads. |
| Oregon DEQ / ORS 358.920 | Stormwater, erosion control, archaeological protection | Requires erosion control measures and mandates stopping work if archaeological resources are discovered. |
| Deschutes County / City of Bend | Site disturbance and grading approvals | Bend has separate review timelines; volcanic soil and elevation affect excavation conditions. |

How We Run an Excavation Project
1.
Scope and Permits Before Equipment Is Booked
We review site conditions, the build sequence, and permit jurisdiction first. Oregon 811 locates, city grading permits, and coordination with Marion County or Deschutes County go into the plan at this stage. Not after the machine is on site.
2.
Excavation with One Owner-Led Point of Contact
Work follows the approved scope. Site access, staging, and spoil removal are planned before mobilization. There is no handoff between the person who scoped the job and the crew running it.
3.
Final Grade Walkthrough and Warranty Delivery
We will walk the finished site with you before the equipment leaves. Grade elevations are confirmed, and drainage is checked. A 1-year workmanship warranty is delivered at project close.
Oregon 811 locates, grading permits, and site access are confirmed before equipment is scheduled. If you are planning excavation in Salem, Keizer, or Central Oregon, start by talking through your scope.

FAQs
Excavation removes soil to reach the depth needed for foundations, utilities, or drainage systems. Grading shapes the ground surface after digging so water flows away from structures and the site matches the planned elevation. Most residential projects require both steps. Excavation creates depth and structure. Grading finishes the site and controls drainage.
Contractors dig until they reach undisturbed native soil that can carry structural loads. Organic topsoil and loose fill are removed first because they settle over time. Engineers may also require compaction testing. Residential building codes require foundations to bear on undisturbed native soil or properly compacted engineered fill capable of supporting structural loads.
Residential excavation usually involves hydraulic excavators, skid steers, and compact track loaders. Large excavators handle deep digging and heavy earthmoving. Smaller machines work in tight residential lots where access is limited. The equipment size depends on site access, soil conditions, and the depth required for the work.
Excavated soil is called spoil. Some spoil can be reused on site for backfill or grading if the soil structure is stable. Material with organic content or excess moisture usually cannot support loads. That soil is hauled away and replaced with engineered fill that compacts properly.
Excavation can happen year round, but the best conditions usually occur from late spring through early fall. Winter rain saturates the clay soils common in the Willamette Valley, reducing bearing strength and making compaction harder. Drier months allow more stable digging conditions for foundations, grading, and drainage work.
