Most residential excavation work in Clark County runs $1,500–$6,500, with equipment and operator at $110–$190 per hour. The final number is set by how much material moves, how steep the site is, what the soil contains, whether equipment can reach the work area, and how far spoil needs to travel.
Volume of material moved is the largest single cost driver in excavation work. A project that removes two hundred cubic yards of soil takes proportionally more time and equipment than one that moves forty. The relationship is not perfectly linear—setup and mobilization cost the same either way—but volume is the number one factor separating a modest residential project from a substantial one. If you can reduce the volume by cutting and filling on-site rather than hauling spoil out, you reduce cost. If the scope requires importing fill, budget similarly for trucking and compacted placement of that material, because it travels both directions at real cost.
Slope and equipment access are closely related factors. A flat suburban lot in Five Corners where a mid-size excavator can pull directly onto the work area from the street is a different proposition from a sloped parcel in Hockinson where the machine must negotiate a narrow entry and work on an angle for the entire job. Steep sites require slower, more deliberate machine work, limit the size of equipment that can safely access the area, and sometimes require temporary access construction before the excavation proper can begin. Dense landscaping, a tight fence line, or a structure immediately adjacent to the dig area has a similar effect on production rates and therefore on cost—everything the machine cannot freely maneuver around adds time.
Soil and rock conditions vary more within Clark County than most people expect. The county's lower-elevation soils trend clay-heavy, and clay takes more time to cut and load cleanly than sandy or loamy material. Buried rock—whether a continuous ledge or isolated boulders—can change the cost of a project substantially when it is encountered and requires breaking or removal. Clark County elevation ranges from about 49 feet near Salmon Creek to over 700 feet near Camas and Yacolt, and subsurface conditions shift accordingly. There is no reliable way to price for buried rock without probing the site first; a written estimate should specify clearly how unexpected rock will be handled and priced if it is encountered.
Haul distance and disposal round out the major cost variables. Spoil that stays on-site costs nothing to dispose of, though it does require a place to put it and a plan for what happens with it long-term. Spoil that leaves via truck runs $60–$120 per cubic yard for haul-off, including truck time and tipping fees. A project that moves significant material off-site can have haul costs that rival the excavation cost itself. This matters when comparing quotes, because contractors handle haul-off pricing differently—some bundle it into the project at an assumed volume, some bill it as a separate line item based on actual loads. Quotes that treat haul-off differently are not directly comparable until you adjust for it.
If it needs equipment, Vancouver Excavation Co. quotes it in writing.
The overall residential range of $1,500–$6,500 covers the equipment and earthmoving work on a typical project. Breaking that down by type gives a more useful target when planning. Site preparation for a home pad on a quarter-acre to half-acre parcel typically runs $2,500–$8,000 depending on how much cut and fill the lot requires. Foundation and footing excavation for an average home runs $2,000–$6,500. Gravel driveway excavation and base preparation on a sixteen- foot-by-one-hundred-foot run lands in the $2,500–$6,000 range. Utility trenching runs $12–$30 per linear foot depending on depth, soil, and haul-off. French drain and drainage system installation over a 100–150-foot run costs $1,800–$5,500 installed. Land clearing runs more per acre than most people plan for: light brush on open ground comes in at $1,500–$3,500 per acre, while wooded ground with stumps runs $3,500–$9,000 per acre.
Equipment and operator time underlies all of those figures. At $110–$190 per hour for the equipment and the operator running it, you can work backward from scope once you have a rough sense of how many machine hours a project involves. That rate covers a competent operator in a maintained machine, fuel, insurance, and the overhead of a licensed contractor. Bids that come in substantially below this range merit a question about insurance and licensing—they matter for liability when equipment is operating on your property.
Get a written estimate after a site visit rather than committing to a phone quote. Excavation cost depends on site-specific conditions—soil, access, slope, buried obstructions, haul situation—that a phone description rarely captures accurately. A contractor who quotes confidently without seeing the site is working from assumptions that may not match what they find on arrival. A site visit typically takes under an hour; a cost dispute mid-job takes substantially longer to resolve and leaves a worse outcome for everyone involved.
Plenty of readers handle excavation cost themselves. We are here if not.
The most common budgeting mistake on excavation projects is not accounting for haul-off as a separate cost. Many homeowners budget for the digging and assume the spoil disappears without cost. It does not. Material that leaves the property travels by truck to a facility that charges a tipping fee. At $60–$120 per cubic yard for haul-off, a project that moves a hundred cubic yards of soil off-site can add significantly to the total project cost on the disposal side alone. Before accepting any excavation quote, confirm whether haul-off is included, at what assumed volume, and what happens if actual haul-off volume differs from the estimate.
The second mistake is treating a phone quote as a reliable number and then being surprised by the final invoice. Excavation contractors who quote by phone are working from the homeowner's description, which typically underestimates access constraints, soil difficulty, and the volume of material involved. The gap between a phone quote and a final invoice on an excavation project is often large enough to matter. Request a site visit before committing, and get the estimate in writing with explicit terms for how unexpected conditions—rock, buried concrete, softer soil than anticipated—are handled and priced.
A third mistake is scheduling compaction-critical excavation work during Clark County's wet season without understanding what that means for the end result. Clay-heavy soils compacted while saturated will pass the initial earthmoving phase but may fail a compaction test required by an inspection, or simply settle unevenly once the material dries. For work that will bear structural load—a building pad, a driveway base—attempting it in wet conditions can mean doing the work twice: once in winter and once again in summer to remediate the result. Budget for the right window rather than for the cheaper scheduling option that produces rework.
Small earthmoving jobs are within a homeowner's reach if the scope is genuinely modest. Spreading a truckload of topsoil, regrading a mild slope away from a foundation with a rented compact tractor, or filling a low corner of the yard does not inherently require a licensed excavation contractor. If the area is manageable, the material volume is small, and the result does not need to meet a compaction specification for an inspection, renting equipment and doing it yourself is a reasonable option. Confirm before you start whether the project crosses a permit threshold—call Clark County or your city's permit office and describe the scope. That call takes about five minutes and gives you a definitive answer at no cost.
Call a professional when the volume of material exceeds what compact rental equipment handles efficiently, when precision finish grades matter for drainage or construction, when the project involves excavating for a foundation or a structural surface, or when a permit requires compaction documentation going through inspection. Larger machines move Clark County's clay soils faster and more cleanly than compact rental equipment, and the cost difference per cubic yard is smaller than most people expect once you factor in the time spent struggling with underpowered equipment on difficult material.
Under Washington RCW 19.122.030, any excavation—by a homeowner or a contractor—requires marking the proposed work area in white and notifying the 811 one-call system at least two full business days, and no more than ten business days, before breaking ground. The service is free, the requirement is mandatory, and it applies to every excavation regardless of size. Clark County has buried utilities crossing residential properties that are not always obvious from the surface. A utility strike during excavation is a serious safety event and a potential liability regardless of whether you hired a contractor or did the work yourself. Call 811 before any ground is broken, every time.
Your parcel may differ — we check before quoting.
Excavation cost depends on site conditions that are not visible in a description: actual soil composition, buried obstacles, equipment access constraints, and haul distance. Two lots in the same Clark County neighborhood can cost substantially different amounts to excavate if one has tight access and clay with rock while the other has an open drive and uniform loam. A quote is only reliable after someone has walked and assessed the site.
It varies by contractor and how the estimate is written. Some bundle haul-off at an assumed volume; others bill it separately as a line item based on actual truck loads. When comparing quotes, confirm how each one treats haul-off and at what assumed volume. A quote that excludes haul-off can appear lower while actually costing more once you add the disposal cost that the other quote already includes.
The same hourly equipment and operator rate applies—$110–$190 per hour—but commercial projects involve larger equipment, longer mobilization, more permitting, and far greater material volumes. The per-cubic-yard cost can be lower on large commercial jobs due to scale, but the overall project cost is much higher. Residential pricing is what applies to home sites, driveways, and typical yard and drainage work across Clark County.
Land clearing on wooded ground with stumps runs $3,500–$9,000 per acre in Clark County, covering felling, stump work, chipping or hauling brush, and rough grading the cleared surface. Light brush without significant tree cover runs $1,500–$3,500 per acre. Wooded lots with dense timber, large stumps, or restricted equipment access land toward the high end of the wooded range.
Not reliably. Excavation cost is driven by site-specific conditions—soil, slope, access, buried obstructions, haul situation—that a phone description rarely captures accurately. Contractors quoting without a site visit are working from assumptions that may not match what they find on arrival. Request a site visit and a written estimate. The visit typically takes under an hour and the written price is the only number you can actually count on.
We offer written estimates after a site visit—not phone guesses—because excavation cost is too site-specific for a reliable number without seeing the ground. Tell us the address and what you are trying to accomplish, and we will schedule a visit and give you a written price with haul-off terms clearly stated.
