River-bottom drainage and excavation work in Washougal — where the ground sits at 82 feet and the water table reminds you of that every wet season.
Washougal sits at 82 feet above sea level — the lowest incorporated city this crew regularly serves. Camas, just across the Washougal River to the west, sits at 712 feet. Hockinson, inland to the north, is at 387 feet. Vancouver proper is at 180. That 82-foot number is not trivia. It is the single most important fact about doing excavation work here, because it means the ground behaves differently from almost every other community in Clark County.
The city covers about 6.8 square miles on the north bank of the Columbia River, 18 miles east of Vancouver along State Route 14. Incorporated in November 1908 with a population that has since grown to 17,039 as of the 2020 Census, Washougal is also the southernmost incorporated city in Washington State — bounded to the south by the Columbia itself and to the west by the Washougal River, which runs along the north side of downtown before joining the Columbia just downstream.
What that geography means for the ground: you are in river-bottom country. The water table is genuinely high. The soil near the Columbia floodplain holds moisture long into the spring and picks it back up early in the fall. Seasonal excavation windows are narrower at the bottom than they are even a few miles inland. This is not a hillside runoff problem — the kind of drainage challenge where you cut a swale and redirect surface water. At 82 feet, it is often a groundwater problem, and that is a different fix requiring different equipment and different design.
The Washougal River adds another layer. It separates the city from Camas and keeps the ground on the Washougal side wetter than topography alone would suggest. Trench walls in the saturated zone want to slump, especially in the wet months. Anyone pricing excavation work here without accounting for those conditions is pricing a different job.
Ground conditions in Washougal decide the method and the price more than anything else. Our Clark County crew reads them on site first.
Drainage is the most common reason property owners in Washougal call us, and the work almost always turns out to be more about groundwater than surface runoff. A French drain in Hockinson at 387 feet is intercepting water moving downhill across a slope. A French drain in Washougal at 82 feet is often fighting a water table that rises from below, which means the drain needs to be designed to the actual saturated layer — not just laid in the general vicinity of the wet spot.
Site preparation and grading here require an honest read of the low ground before anything gets leveled. Fill placed on floodplain-adjacent soil without addressing the drainage first compacts unevenly and settles over time. We look at where water sits after a rain, where it drains to, and whether it has anywhere to go before we quote a grading job. Those are questions a site visit answers in about twenty minutes.
Utility trenching in older Washougal neighborhoods comes with its own character. The SR 14 corridor drew a wave of summer-home development in the late 1920s after the east-west highway along the Columbia opened in 1927. The utilities serving those parcels are old and, in many cases, shallow. We locate carefully before we cut. There is no shortcut on this step, particularly in the blocks nearest the river where the original infrastructure has been buried, extended, and buried again over nearly a century.
Recreational fishing on the Washougal River — steelhead and salmon — means water-adjacent work near the river has to be planned around both erosion and any applicable buffer setbacks. We do not design those setbacks, but we factor them into access and staging on jobs close to the water.
Washougal is an incorporated city. That one fact changes the permit path completely. Building, grading, and erosion-control permits are issued by the City of Washougal — not Clark County. Clark County handles the unincorporated areas of the county. If your address is within Washougal city limits, the county permit counter is not your starting point.
We see this confusion come up regularly, especially with property owners who have done work on rural parcels in the county before and assume the same office applies. Washougal incorporated in November 1908 and has had its own municipal government ever since. The permit counter is city, not county, and the inspectors who sign off on grading and erosion control work inside city limits are city staff.
Washington's utility locate law applies to every excavation in the state regardless of who issues the permit. RCW 19.122.030 requires two things before any digging starts: white-line the boundary of the planned excavation, then give notice to the one-call system not less than two and not more than ten full business days before the work-to-begin date. A general contractor is permitted to give that notice, but the statute puts legal responsibility on the excavator. We give our own notice on every job. We do not start inside the waiting window, and we do not rely on anyone else's call to satisfy our legal obligation.
Getting the Washougal jurisdiction right the first time saves a week. Our crew checks it before scheduling.
Low ground near the Columbia River does not behave like the rest of Clark County in the shoulder seasons. In a typical year, rain runs through fall, winter, and spring and stops around mid-June, leaving a dry window through September. On elevated ground like Hockinson, the soil firms up weeks before the flats do. In Washougal at 82 feet, floodplain-adjacent parcels can hold standing water into late spring and go soft again early in the fall. The effective dry window is shorter here than it is inland.
Wet-season work in Washougal is possible, but it carries real trade-offs. Soft ground ruts under equipment. A tracked machine leaves less damage than a wheeled one, but it still leaves damage if the soil is saturated. We are direct about this when we walk a property: if the ground is not ready, we say so rather than start a job that leaves the yard worse than we found it.
Street access from SR 14 is generally good — the highway runs along the Columbia and connects the city east and west without the narrow county roads that complicate equipment delivery in some inland communities. The constraint in Washougal tends to be getting equipment from the street to the work area, not getting equipment to the street. River-facing parcels often have grade changes, retaining structures, or mature trees near the work zone that decide what machine fits the job before anything else does.
We would rather move a Washougal job a month than fight the weather. That is the approach at Vancouver Excavation Co..
Most residential excavation work in Clark County falls between $1,500 and $6,500, and Washougal jobs land across that entire range. The low end covers contained drainage work on an accessible lot. The high end shows up when the drainage problem is a groundwater problem, when the wet season forces staged work, or when equipment access to a river-facing parcel is restricted.
Low-ground drainage in particular can run toward the higher end of the band because the design is more complex and the installation has to account for a rising water table, not just surface flow. A drain system that solves a groundwater problem is a different material and labor quantity than one sized only for rain moving across a slope. We will not know which situation a given property presents until we see it in person, and we will not put a number on paper until we do.
Site visits are free. We walk the ground, look at the drainage, check the access, and give you a written estimate before any commitment. That visit is also what protects you from a low phone quote that balloons once a crew shows up and sees the actual conditions.

The City of Washougal issues its own building, grading, and erosion-control permits. Washougal is an incorporated city — not an unincorporated part of Clark County — so the county permit counter does not have jurisdiction inside city limits. If your address is within Washougal, start with the city.
Elevation is the short answer. Washougal sits at 82 feet — Camas is at 712 feet, Hockinson at 387 feet. At 82 feet on floodplain-adjacent ground near the Columbia and Washougal Rivers, the water table is genuinely high. Drainage problems here are often groundwater problems rising from below, not just surface runoff moving across a slope. The fix is different: deeper drain placement, different pipe sizing, and a design that accounts for the saturated zone rather than just intercepting rain.
Washington's RCW 19.122.030 applies statewide, including inside Washougal city limits. Before any excavation begins, the planned dig boundary must be white-lined and notice given to the one-call system not less than two and not more than ten full business days before the work-to-begin date. We give that notice ourselves on every job. A general contractor may legally submit the notice, but the statute keeps responsibility with the excavator, so we do not hand that step to anyone else.
Mid-June through September is the reliable dry window in this part of the state. In Washougal, the window can be shorter than it is in higher communities because river-bottom ground at 82 feet holds water later into the spring and picks up moisture earlier in the fall. If you can schedule during that summer window, the ground is firmer and the work goes faster. Wet-season work is possible on parcels with hard surface access, but it carries more risk of ground damage and may require staged scheduling.
It can. The Washougal River runs along the north side of downtown and keeps the water table elevated on the city side. Work close to the river may also fall within buffer setbacks that limit where material can be placed or how erosion control needs to be set up. We factor those conditions into access and staging when we walk the site, and we flag any setback questions before we price the work.
