Asphalt Driveway Cost in Tillamook, Oregon: 2026 Price Guide

What Does an Asphalt Driveway Cost in Tillamook?

Tillamook sits in a broad coastal valley where five rivers meet the bay, surrounded by the dairy farms that made the town's name. That geography — low, flat, river-fed land with a high water table and frequent rain — defines how a driveway gets built here, and what it costs. This is some of the wettest, softest ground in Oregon, and asphalt has to be engineered for it.

Homeowners usually want a single price. The realistic answer is a range. Industry sources have historically reported residential asphalt driveway baselines of roughly $3 to $7 per square foot over a sound base. For a typical 600-square-foot two-car driveway, that's a historically reported baseline of about $1,800 to $4,200. In Tillamook, actual projects often run higher once you account for the soft, saturated subgrade and the cost of hauling hot mix to a coastal town with no nearby asphalt plant.

Whether you're paving a farmhouse approach out on the flats or a driveway in town, knowing what each cost component covers helps you budget and compare quotes with confidence.

Tillamook Asphalt Driveway Prices: Detailed Breakdown

Per-Square-Foot Installation

Industry baseline ranges shown below. Actual coastal-valley costs run higher with subgrade, drainage, or haul factors.

Driveway Size	Approx. Square Footage	Industry Baseline Range
1-car	300–400 sq ft	$1,000–$2,800
2-car	500–700 sq ft	$1,800–$4,200
3-car / long	800–1,200 sq ft	$2,800–$7,500

Larger driveways cost a bit less per square foot as setup costs spread out, but Tillamook's haul distance from inland asphalt plants narrows that savings.

Cost Components

Baseline industry ranges. Actual figures depend on soil, access, and drainage needs.

Component	Industry Baseline Range
Excavation & grading	$1.50–$4.00 per sq ft
Crushed rock base (4–8 in)	$1.00–$3.00 per sq ft
Old driveway removal & haul-off	$1.00–$3.50 per sq ft
Asphalt surface course (2–3 in)	$2.00–$5.00 per sq ft
Geotextile fabric over soft soil	$0.30–$0.80 per sq ft

On Tillamook's soft, river-valley ground, geotextile fabric and a deeper base are common necessities, not upgrades. They keep the structural rock from sinking into the wet subgrade.

Removal, Slope & Drainage Factors

Industry baseline ranges. Tillamook's high water table makes drainage a frequent cost driver.

Factor	Typical Added Cost
Tear-out of existing concrete/asphalt	$1.00–$3.50 per sq ft
Steep approach regrading	$500–$2,500
Channel or trench drain	$30–$75 per linear foot
Culvert at road approach	$800–$2,500

With Tillamook averaging close to 90 inches of rain a year, drainage is rarely an afterthought. Moving water off and away from the driveway is essential to keeping it from failing early.

Factors That Affect Driveway Cost in Tillamook

Soft Coastal-Valley Subgrade

The flat land around Tillamook Bay is rich farm soil and river deposits — great for grass, tough for pavement. A driveway built on unimproved ground here will settle and rut. Proper base depth, compaction, and fabric add up front cost but determine whether the driveway lasts. Salt air off the bay also speeds surface oxidation, making consistent asphalt maintenance more important.

Haul Distance and Access

There's no asphalt plant in Tillamook. Hot mix is trucked over the Coast Range from inland plants and has a limited working window before it cools too much to compact properly. That logistics cost is real and shows up on coastal quotes. Long rural driveways out on the dairy flats add material and labor too.

Driveway Size and Layout

Size is the biggest lever on total cost. A simple rectangular pad is far cheaper per square foot than a long farm approach or a curved layout. See our driveway cost by size guide for how square footage maps to price.

Timing and Scheduling

Tillamook's paving window is narrow — crews need dry pavement and temperatures above about 50°F, which the wet coastal climate limits to late spring through early fall. Booking ahead of summer usually means better scheduling and pricing.

Current Market Reality

The baselines above reflect historically reported averages. In Tillamook, actual costs frequently exceed them because of:

• Subgrade correction — Soft, saturated valley soil routinely needs fabric and deeper base rock
• Haul premiums — Trucking hot mix to a remote coastal town adds cost no inland job carries
• Drainage scope — Heavy rain and a high water table mean more drains, culverts, and grading
• Access difficulty — Long rural approaches and tight in-town lots both add labor
• Material upgrades — Thicker surface courses and better binders cost more but resist coastal wear

Use any published range as a starting reference, never a budget target. A site visit is the only way to get a number that reflects your lot.

How Tillamook Compares to Inland Oregon

Coastal-valley driveway work generally runs higher than comparable inland jobs in Salem or Eugene, driven by haul distance, drainage demands, and subgrade correction. A driveway that sits mid-range inland often lands toward the upper end in Tillamook.

What a Contractor Can't See Until Work Begins

Even a careful estimate can shift once excavation starts:

• Water table higher than expected — Saturated subgrade may need dewatering or extra base
• Soft spots in the valley soil — Localized weak ground requires over-excavation and import of rock
• Buried debris or old fill — Common on properties with a long history of use
• Hidden drainage paths — Low spots that channel runoff under the pad
• Organic layers — Buried topsoil or peat that won't support pavement

This is why an on-site assessment beats any price chart. A contractor who walks your lot gives a far more accurate quote than any average.
