Amity is a small wine-country town in the southern stretch of Yamhill County, sitting in the open Willamette Valley between McMinnville and the Polk County line along Highway 99W. The surrounding hills are dotted with vineyards and the town itself is mostly residential with a modest commercial core. Paving here runs to driveways, vineyard and farm-access drives, tasting-room lots, and small-commercial property. The ground is classic valley floor: fine, slow-draining soils that stay wet through winter, which puts the whole job on the sub-base.
This guide covers what asphalt paving involves in Amity, the cost ranges to plan for, and the permitting you should expect.
Asphalt pricing moves with surface area, sub-base condition, site access, and the going rate for liquid asphalt. The figures below are industry baselines, not a Cojo quote, and real Oregon costs frequently run higher.
Industry baseline ranges shown below. Actual costs vary with sub-base work, thickness, site access, and material pricing.
| Project Type | Typical Size | Industry Baseline Range |
|---|---|---|
| Residential driveway (new) | 600–1,000 sq ft | $4,000–$8,000 |
| Driveway resurface (overlay) | 600–1,000 sq ft | $2,500–$5,000 |
| Small commercial lot | 5,000–10,000 sq ft | $25,000–$60,000 |
The valley floor around Amity drains slowly. The fine silt and clay under most properties here holds water through the rainy season and loses strength when saturated, and pavement built on a base that shifts will alligator-crack and rut within a few seasons. Vineyard-access drives that carry tractors and harvest trucks see even more load, which makes the base spec matter that much more.
A proper build for these soils means excavating to a stable depth, laying geotextile fabric where the subgrade is soft, and compacting a deep crushed-rock base in lifts. The aggregate section often needs to be thicker here than on the better-drained hillside vineyards. Drainage gets designed in from the start so water sheds off the surface rather than ponding and soaking the edges.
A residential driveway in Amity typically goes down as 2 to 3 inches of compacted asphalt over 4 to 6 inches of base. A tasting-room lot, commercial drive, or farm-access road carrying trucks and equipment needs a heavier section, often 3 to 4 inches of asphalt over 6 to 8 inches of base, sometimes in two lifts. Match the structure to the real load.
Most residential driveway paving inside Amity does not require a building permit, but access connections do. Highway 99W runs through Amity and is an ODOT facility, so any new or modified approach onto it needs an ODOT approach permit. Tie-ins to county-maintained roads go through Yamhill County's road department.
Projects that disturb significant ground or alter drainage can trigger county erosion-control and stormwater rules. A contractor who knows this area will identify which thresholds your project is near and pull the right permits before breaking ground.
A typical Amity job runs through:
Residential driveways often wrap in a day or two once the base is ready. Commercial and farm-access jobs take longer.
Asphalt needs warm, dry weather to bond and compact, so the reliable paving window in the valley runs roughly late spring through early fall. The summer months are busiest for every contractor in Yamhill County, so booking in spring for early-summer work usually secures better scheduling. New pavement benefits from sealcoating later, but let fresh asphalt cure for several months first.

Amity's soft valley ground and its mix of residential, commercial, and farm-access paving reward a contractor who builds the base for the real soil and load rather than pouring the same section everywhere. Serious drainage design and proper ODOT and county permitting are what keep pavement from failing early.
