Dirt hauling in Tigard is the trucking that moves excavated spoil off a site or delivers clean fill to it, supporting the steady infill, remodel, and development work across the southwest Portland metro. Tigard is a built-out suburb, so hauling here often means working tight residential lots, established neighborhoods, and busy commercial corridors where access is the main challenge. The soil is Willamette Valley clay, heavy and sticky when wet, and truck size and maneuvering room frequently matter as much as the load count. Cost tracks loads, haul distance, and access, with the dry season the practical time for larger moves.
On a Tigard job, dirt hauling handles several related tasks:
Loads are the unit of measure, and load count is the biggest cost driver. An Oregon excavation contractor guide approach ties hauling to the excavation so trucks are used efficiently, which matters on tight suburban sites where every trip counts.
One detail that trips people up: spoil and fill are not interchangeable. Excavated clay coming out of a Tigard foundation is heavy, wet, and generally not reusable as structural fill, so it leaves the site as export. The clean structural fill, sand, or gravel that builds a pad back to grade is a separate material that gets delivered in. Topsoil is a third category, stripped and stockpiled separately because it is organic and cannot carry load. Sorting those streams correctly is part of what keeps the truck count -- and the bill -- honest.
On a built-out suburban lot, the truck decision is as important as the load count. A full-size dump or transfer truck moves the most dirt per trip and per dollar, but it needs room to turn, back in, and load without tearing up a driveway, a lawn, or a neighbor's frontage. Many Tigard infill and remodel sites cannot take one, so the crew steps down to a smaller truck or a dump trailer that fits the access. Smaller trucks mean more trips to move the same volume, which trades access for trip count -- a real cost tradeoff that only shows up once someone has actually looked at the site. The choice comes down to a few things:
Getting this right up front is why an on-site look beats a phone estimate for Tigard hauling.
In a built-out suburb like Tigard, the defining factor is usually not the soil, it is getting trucks to the dirt.
The underlying Willamette Valley clay behaves like the rest of the metro: heavy and sticky when wet. That makes the dry-season window, roughly May through October, the best time for major hauling, when the ground is firm and trucks are not tracking mud through a neighborhood.
| Factor | Effect on cost |
|---|---|
| Number of loads | The primary driver, set by material volume |
| Site access | Often the swing factor on tight suburban lots |
| Haul distance | Farther disposal or fill sources add cost |
| Disposal fees | Charged per load at the receiving site |
| Material type | Clean fill is cheapest; mixed or contaminated soil costs more |
| Work item | Industry baseline range |
|---|---|
| Dump truck haul-off, per load (10-14 cu yd) | $250 - $750+ per load |
| Dump / disposal fee | $75 - $300+ per load |
| Fill dirt, delivered, per cu yd | $20 - $75+ per cu yd |
| Excavator + operator, hourly | $150 - $350+ per hour |
| Mobilization fee | $250 - $800+ flat |
Treat those ranges as a floor. On real Tigard jobs the total often runs two to three times a back-of-the-envelope estimate once access forces smaller trucks and more trips, disposal sites sit farther out, or wet clay adds weight and slows loading. A minimum job callout of $500 to $1,500+ applies to small moves, so a single load rarely scales down to the price of the material alone. Suspected contaminated or mixed soil is the biggest wildcard -- it can require testing and a special disposal site, which changes the cost picture entirely. The reliable number always comes from a look at the actual lot.
Tigard's suburban fabric means access planning is central. Heavy hauling can trigger local truck-route rules, and oversize or overweight loads may need permits. Loading on or near a public street can require care and, in some cases, coordination with the city. Every dig starts with an 811 locate, especially important on lots with mature landscaping and older utilities. Because the southwest metro cities run together, we also cover dirt hauling in Tualatin and dirt hauling in Lake Oswego with the same crews.
Dirt hauling in Tigard is a load-count job where suburban access sets the pace. Match the trucks to the lot, plan the staging and route, respect the clay and the season, and spoil leaves cleanly while fill arrives on schedule. On tight infill and remodel sites, a crew that knows how to work in a neighborhood makes the difference.
