What Does an Asphalt Driveway Cost in Tigard?
Tigard sits in the heart of Washington County, a mature southwest-metro suburb where established neighborhoods, newer subdivisions, and the hillsides around Bull Mountain all sit within a few miles of each other. That mix matters for driveway pricing: a flat lot in an older Tigard neighborhood and a sloped lot climbing Bull Mountain are very different jobs. Add the Portland-area wet winters and the silty clay soils common across the county, and you have the main local factors that shape what you pay.
For a standard residential project, industry sources have historically reported baseline ranges of $3 to $7 per square foot for a new asphalt driveway. A common 600-square-foot two-car driveway has been baselined around $1,800 to $4,200, with larger or sloped projects running higher. These are reference points, not firm quotes — actual Tigard costs depend on removal, base prep, slope, and site access.
Whether you are repaving a driveway in an established neighborhood off Walnut Street or building a new one on a hillside lot, understanding the breakdown helps you budget and read quotes with confidence.

|---|---|---|
| Single car | 300–400 sq ft | $1,000–$2,800 |
| Two car | 600–800 sq ft | $1,800–$5,600 |
| Three car / extended | 1,000–1,200 sq ft | $3,000–$8,400 |
| Sloped / hillside lot | varies | premium over flat |
What Goes Into the Price
Baseline cost components — the mix is what makes two Tigard driveways quote differently.
| Cost Component | Industry Baseline Range |
|---|---|
| Old driveway removal & haul-off | $1–$3 per sq ft |
| Excavation & grading | $1–$3 per sq ft |
| Aggregate base rock (4–8 in) | $1–$3 per sq ft |
| Asphalt surface (2–3 in) | $2–$5 per sq ft |
| Steep slope / drainage work | varies widely |
Factors That Affect Driveway Cost in Tigard
Slope and Drainage
This is the defining local factor. Many Tigard lots, especially toward Bull Mountain, carry real grade. Sloped driveways need careful drainage so winter runoff does not undermine the base or pool at the garage. Channel drains, regrading, traction finishes, and edge support all add to the quote — and skipping them shortens the driveway's life.
Soil and Base Prep
Washington County's silty clay soils drain slowly and hold moisture through the wet season. A thin base lets asphalt flex and crack; a deeper, well-compacted base prevents it. That base work raises the upfront cost but is the best money you spend on the job.
Removal of the Old Surface
Repaving an established Tigard driveway means tearing out and hauling off the old asphalt or concrete. A failed base underneath can add labor.
Driveway Size and Complexity
Simple rectangular driveways are cheapest. Curves, turnarounds, parking pads, and hillside geometry add labor and material. For how size drives price statewide, see our guide on asphalt driveway cost across Oregon.
Current Market Reality
The baseline ranges above reflect historically reported averages. Real Tigard projects often exceed them because of:
- Slope and drainage on hillside lots near Bull Mountain
- Removal and disposal of an old surface before new work
- Base remediation in wet, clay-heavy subgrade
- Material and fuel pricing, since asphalt tracks oil and season
- Tight lot access in established neighborhoods that slows equipment

Why Local Conditions Matter in Washington County
Tigard's blend of flat established lots and steep hillside parcels means there is no single "Tigard price" — the grade of your lot is often the biggest variable. On a hillside, drainage and traction work that a flat lot never needs become essential, both for the driveway's lifespan and for safe winter footing. On any lot, the wet-season saturation common to Washington County makes base prep the deciding factor in how long the asphalt lasts.
Regular upkeep extends that life. Our asphalt driveway maintenance services cover the sealcoating and crack repair that protect the surface through the wet season. For the full picture of owning an asphalt driveway in Oregon, our complete asphalt driveway guide for Oregon ties it together.
