Asphalt Driveway Cost in Forest Grove, Oregon: 2026 Price Guide

What Does an Asphalt Driveway Cost in Forest Grove?

Forest Grove sits in the western reach of Washington County, where Pacific University, tree-lined historic streets, and a growing ring of newer subdivisions all share the same wet-winter, dry-summer climate. Whether you're paving a first driveway on a new build off Highway 47 or replacing a worn surface on one of the older homes near downtown, knowing the real cost range helps you budget and compare quotes without guesswork.

Asphalt driveway cost in Forest Grove comes down to size, base condition, slope, and how much old material has to be removed. This guide lays out the 2026 baseline ranges and the factors that move your number up or down.

Forest Grove Asphalt Driveway Prices: By the Square Foot

Most asphalt driveway pricing starts from a per-square-foot rate that bundles material, labor, and equipment.

Industry baseline ranges shown below. Actual costs vary based on base condition, removal, slope, paving thickness, and current market conditions.

Project Type	Industry Baseline per Sq Ft
New driveway (full base + paving)	$7–$13
Resurfacing / overlay (sound base)	$3–$5
Gravel-to-asphalt conversion	$5–$10

A new asphalt driveway carries the highest per-foot cost because it includes excavation, base rock, compaction, and paving from the ground up. Resurfacing costs less because it reuses the existing base. For the statewide picture behind these numbers, see our guide on how much an asphalt driveway costs in Oregon.

Cost by Driveway Size in Forest Grove

Industry baseline ranges for a new asphalt driveway. Actual totals depend on base work, removal, and site conditions.

Driveway Size	Approx. Square Footage	Industry Baseline Range
Single-car	400–600 sq ft	$3,000–$7,000
Two-car	600–900 sq ft	$4,500–$11,000
Three-car	900–1,400 sq ft	$6,500–$16,000
Long / rural	1,500–2,500+ sq ft	$10,000–$28,000+

Per-square-foot cost tends to drop as driveways get larger because mobilization and setup are spread across more area. For a fuller breakdown by car count and square footage, our driveway cost by size guide goes deeper.

What Drives Forest Grove Driveway Cost Up or Down

Base Condition and Soil

Washington County's western edge carries a mix of valley clay and silty loam that holds water through the wet months. A solid driveway needs adequate base rock depth and good compaction to handle that seasonal moisture — and that base work is a real share of the total cost. Skimping here is the most common reason driveways fail early.

Removal of the Old Surface

Replacing an existing driveway adds demolition and hauling. Tearing out old asphalt or a failed concrete slab can add meaningfully to the project versus paving over bare ground.

Slope and Drainage

Forest Grove's terrain ranges from flat valley lots to gently sloped properties closer to the Gales Creek and foothill areas. Sloped driveways need extra grading and drainage attention, both of which add labor.

Paving Thickness

Standard residential driveways use a 2- to 3-inch surface over a compacted base. Driveways that carry RVs, trailers, or heavier vehicles call for more thickness, which raises material cost.

Material and Market Conditions

Asphalt is petroleum-based, so oil prices, hauling distance, and contractor availability all influence pricing season to season.

Choosing Asphalt in the Forest Grove Climate

Asphalt is the dominant driveway material across Washington County for good reason: it handles the freeze-thaw cycles and constant winter moisture of the western valley better than many alternatives, and it costs less up front than concrete or pavers. Its flexibility lets it move slightly with seasonal ground shifts rather than cracking the way rigid surfaces can. If you're weighing your options, our asphalt vs. concrete driveway in Oregon comparison covers the cost and climate trade-offs in detail.

The dark surface also sheds the valley's frequent winter rain quickly and warms in summer sun, which helps it dry out. Pairing the right thickness with proper drainage is what makes asphalt last in Forest Grove's conditions.

Protecting the Investment

A new driveway holds its value when it's maintained. Plan to sealcoat after the first six to twelve months of curing, keep cracks filled before water gets in, and follow a regular maintenance schedule. Our asphalt maintenance services cover this work, and the complete asphalt driveway guide for Oregon ties cost, installation, and upkeep into one plan.

Why On-Site Quotes Beat Price Charts

Published ranges are a starting point, not a budget target. The two biggest unknowns — base condition under the surface and how your lot drains — only become clear when a contractor walks the site. A Forest Grove driveway on stable, well-draining ground costs far less to build than one over saturated clay that needs base rebuilding and drainage work. The accurate number always comes from an in-person assessment.
