Cojo provides asphalt paving services across Tualatin, OR -- new paving, repair, pothole patching, driveway work, sealcoating, parking lot striping, and ADA curb-ramp work. We dispatch crews from our Hood River HQ to Washington County for projects ranging from a Stafford-basin residential driveway to a Tualatin industrial-park heavy-truck lot. This overview lays out our Tualatin service offering, the local conditions that drive scope decisions, and the budget ranges to plan against. For statewide pricing context, see our Oregon paving cost guide.
Services We Offer in Tualatin
Asphalt work splits into five service categories, and most Tualatin commercial projects need two or three of them combined on a single mobilization.
- New paving: driveways, parking lots, private roads, industrial-park access drives. Includes excavation, base prep, hot-mix placement, and finish rolling.
- Repair and patching: pothole repair, crack sealing, alligator-crack patching, edge-spall repair, full-depth section replacement.
- Driveway work: new asphalt driveways, resurfacing, repair, and apron coordination with Tualatin and Washington County permitting.
- Sealcoating: maintenance sealcoat application to extend asphalt life and resist UV oxidation. See Tualatin sealcoating for cadence and spec detail.
- Parking lot striping and ADA work: layout design, restriping, ADA-compliant accessible stalls and curb ramps, pavement marking. See Tualatin parking lot striping for layout standards.
A typical Tualatin commercial paving project bundles new paving or repair with sealcoating and striping on the same mobilization. Bundling amortizes mobilization across services and tightens the tenant-disruption window.
Tualatin Conditions That Drive Scope
Tualatin sits in the southwest Portland metro on the Tualatin River drainage. Annual rainfall runs 40 to 45 inches, summers are warm and mostly dry, and the valley sees 15 to 25 freeze-thaw cycles in a typical winter. Soils across the area are dominated by Cascade and Aloha silty clay loam, with patches of poorly drained Wapato on filled wetland margins.
Site conditions worth flagging for Tualatin property owners:
- Industrial-park heavy-truck loading: the Tualatin industrial corridor handles concentrated axle loads at lot entrances, drive aisles, and loading-dock approaches. Heavy-duty sections typically need a thicker structural section (4 inches over an upgraded base) than the rest of the lot.
- Stafford basin drainage: lots on the Stafford side of town can have shallow groundwater that affects base performance.
- Bridgeport Village area soils: Cascade silty clay loam holds water through the wet season; base specs should be thicker than the textbook minimum.
- Washington County stormwater rules: projects near the Tualatin River main stem or in mapped flood plains can trigger detention or treatment work.
- ADA non-compliance on pre-2010 lots: curb-ramp and accessible-stall updates are typically required during any restripe.
A real contractor brings these conditions up during the site walk. Templated quotes from non-local bidders rarely do.
Industry Baseline Range
| Project Type | Cost Per Sq Ft | Typical Total Cost |
|---|---|---|
| Residential driveway (2-car) | $2.00 to $10.00 | $2,000 to $15,000+ |
| Driveway resurfacing (overlay) | $1.50 to $5.00 | $1,500 to $8,000+ |
| Small commercial lot | $2.00 to $10.00 | $8,000 to $60,000+ |
| Mill-and-overlay (commercial) | $3.00 to $7.00 | $30,000 to $150,000+ |
| Full replacement (commercial) | $4.00 to $10.00 | $40,000 to $200,000+ |
| Heavy-duty industrial section | $5.00 to $12.00 | varies by zone |
Current Market Reality
The baseline assumes a flat lot, sound aggregate base, easy access, and no drainage or ADA upgrades. Most Tualatin commercial lots built before 2010 fail at least one of those assumptions, particularly on industrial-park heavy-truck zones where base failure is common after fifteen to twenty years. Pre-2010 commercial lots typically need ADA curb-ramp and stall updates with any restripe. A real bid lines these conditions out as separate items rather than burying them. For broader Oregon pricing context, see our Oregon paving cost guide.
Scheduling Around Tualatin Operations
Asphalt placement needs ambient temperatures above 50 degrees F and dry conditions, which puts the Tualatin working window at roughly May through mid-October. Sealcoating wants 60 degrees F overnight, which compresses the window to mid-May through mid-September. Striping follows paving on the same mobilization.
For commercial industrial-park work, we sequence around dock-door schedules and tenant operations: overnight pours where Tualatin permitting allows, weekend phasing for larger lots, and lane-by-lane closures for drive aisles. We hand the property manager a phase map, cure-time schedule, and back-in-service date per zone before mobilizing.
For Bridgeport Village and other retail-corridor work, we sequence around store hours -- typically overnight or early-morning pours where allowed -- and we coordinate with the leasing office on tenant notifications.
Why Property Owners Choose Cojo
Cojo has been a licensed Oregon contractor since 2009 (CCB licensed and insured). We run our own crews and equipment rather than subbing out, which keeps one accountable party on schedule, change orders, and warranty. Our Hood River HQ dispatches to Tualatin in about two hours via I-84 and I-205, and we treat mobilization as an honest line item.

Permits, Inspections, and Documentation
Tualatin and Washington County permitting varies by scope. New driveways with apron work in the public right-of-way typically need a city apron permit. Commercial work that materially changes impervious area or drainage triggers a stormwater review and may need a sediment-and-erosion control plan, especially for industrial-park sites and lots near the Tualatin River. Bridgeport Village retail work coordinates with leasing-office tenant communication. We handle permit pull and inspection coordination as part of the project scope.
For commercial property managers, we provide a closeout package at project end: as-built drawings if drainage was modified, photographic records of base prep and sub-base before placement, structural-section specs, sealcoat and striping spec sheets, and a one-page warranty summary. The package supports refinance, sale, and insurance-renewal needs. A contractor who can't provide documented closeout is asking the property owner to take the work on faith, which isn't what a 2026 budget should buy. Our standard package goes out within five business days of substantial completion.
Getting a Bid for a Tualatin Project
For a 2026 driveway, industrial-park lot, retail pad, or maintenance project, schedule a site walk. We'll walk the site, core-test where the base looks suspect, scope each zone, and hand you a phased bid with mobilization, sequencing, and warranty terms in writing.
Residential work typically gets an estimate back within 48 to 72 hours of the site walk. Commercial industrial-park work with base-condition cores or stormwater coordination can run seven to ten days. The industrial corridor, the Bridgeport area, downtown Tualatin, and the Stafford basin are all inside our regular Washington County dispatch radius.
