Parking Lot Striping in Washington County, Oregon
Washington County is Oregon's second most populous county and the economic engine of the Portland metro's west side. With over 600,000 residents and home to Intel, Nike, and hundreds of technology, manufacturing, and corporate operations, the county contains one of the largest concentrations of commercial and corporate parking infrastructure in the Pacific Northwest. From Hillsboro's tech campuses and Beaverton's retail corridors to Tigard's commercial centers and Tualatin's industrial parks, Washington County has an enormous inventory of pavement that needs regular striping maintenance.
The Tualatin Valley climate is similar to Portland — maritime-influenced with heavy winter rain and dry, warm summers — providing predictable conditions for scheduling pavement work. The challenge in Washington County is not climate extremes but sheer volume: the concentration of large corporate campuses, shopping centers, and commercial developments means the demand for summer striping far exceeds what casual scheduling can accommodate. Cojo provides professional parking lot striping throughout Washington County.
Washington County Climate and Striping Longevity
Washington County averages 37 to 42 inches of rainfall annually, slightly less than Portland due to the Tualatin Valley's position in the partial rain shadow of the Coast Range. Temperatures are mild — summer highs average in the low 80s and winter lows rarely drop below the mid-20s. This moderate climate is relatively gentle on parking lot paint.
Most Washington County lots need re-striping every 18 to 24 months — among the longest intervals in Oregon. The biggest factor in paint degradation here is not climate but traffic volume. Corporate campus lots with 1,000+ daily vehicle movements degrade faster than the same paint in a low-traffic rural lot simply from the mechanical wear of tires turning in and out of stalls.
The dry season from mid-June through September provides reliable conditions. However, demand from the county's thousands of commercial properties makes peak-season scheduling extremely competitive.
Key Commercial Areas in Washington County
Hillsboro — Tech Corridor
Hillsboro is Washington County's largest city and Oregon's technology capital. Intel's massive Ronler Acres campus and other facilities make it the county's largest private employer, with thousands of parking spaces across multiple campuses. The Hillsboro tech corridor along NE Shute Road, NE Evergreen Parkway, and NE Amberglen Parkway contains dozens of additional technology, pharmaceutical, and corporate campuses with extensive surface lots and parking structures.
The Orenco Station development and nearby commercial areas have added retail, restaurant, and mixed-use parking connected to the MAX light rail. Pacific University's Hillsboro campus adds institutional parking demand.
Beaverton
Beaverton is home to Nike's world headquarters — one of the largest corporate campuses in Oregon — with extensive private parking facilities. The Cedar Hills, Murray Boulevard, and Canyon Road corridors contain major retail centers including Cedar Hills Crossing, Progress Ridge TownSquare, and numerous shopping plazas. Beaverton's position along Highway 217 and TV Highway creates dense commercial corridors with high-traffic lots.
Providence St. Vincent Medical Center, one of the Portland metro's largest hospitals, requires rigorous ADA compliance, emergency access, and patient drop-off zone markings. Beaverton School District's numerous campuses add educational facility parking needs.
Tigard
Tigard's Washington Square Mall is one of the largest shopping centers in Oregon, with extensive surface lots and structured parking that serve regional shoppers. The Pacific Highway (99W) corridor through Tigard includes big-box retail, auto dealerships, and commercial services with large lots. Bridgeport Village, straddling the Tigard-Tualatin border, is a premium retail development with high aesthetic standards for lot maintenance.
Tualatin
Tualatin's industrial areas along SW Tualatin-Sherwood Road and the I-5 corridor contain major distribution centers, manufacturing plants, and corporate offices. These industrial lots need heavy-duty markings for truck traffic and forklift operations. The Tualatin Commons retail area and surrounding commercial development serve the city's growing residential population.
Sherwood, Forest Grove, and Cornelius
The western Washington County communities of Sherwood, Forest Grove, and Cornelius are rapidly growing. Sherwood's Highway 99W corridor has significant retail development. Forest Grove, home to Pacific University, has a classic downtown and growing commercial areas. Cornelius serves as an agricultural and residential community with modest commercial pavement.
Corporate Campus Striping Requirements
Washington County's concentration of major corporate campuses creates specialized striping needs. Intel, Nike, and similar large employers maintain parking lots that function as part of the campus experience — clean, well-organized parking contributes to employee satisfaction, visitor impressions, and corporate image.
Corporate campus lots typically need section numbering, visitor versus employee delineation, reserved executive parking, electric vehicle charging station markings, bicycle parking zones, and precise ADA compliance. Many campuses also require coordination with corporate facilities management and security for scheduling.
Standard ADA requirements apply per the Oregon Structural Specialty Code. Review the striping regulations Oregon guide for details.

Best Time to Stripe in Washington County
The optimal window runs from mid-June through September. The Tualatin Valley dry season is reliable, but peak demand from Washington County's enormous commercial base means contractors book up quickly. Schedule your striping project by March or April to secure a preferred summer date.
Corporate campuses often coordinate striping during company shutdowns, holiday weeks, or shift changes that reduce parking demand. Weekend and overnight work is standard for retail properties like Washington Square Mall. Follow a maintenance checklist to coordinate all pavement maintenance during the dry season.
Frequently Asked Questions
How often should Washington County parking lots be re-striped?
Most lots need re-striping every 18 to 24 months. High-traffic retail lots like Washington Square and corporate campuses with heavy daily use may need attention every 14 to 18 months. Low-traffic office lots can extend to 24 months. See the complete striping guide.Can you handle large corporate campus projects?
Yes. Cojo handles multi-lot corporate campus striping including section numbering, visitor/employee delineation, EV charging markings, and full ADA compliance. Work is coordinated with facilities management and can be phased to minimize disruption. Contact us to discuss campus-scale projects.How far in advance should I book summer striping?
Book by March or April for preferred July or August dates. Washington County has the highest concentration of commercial pavement in the Portland metro, and summer contractor capacity fills quickly. Flexible scheduling or willingness to accept June or September dates may offer faster availability.Do Nike and Intel campuses require different striping approaches?
Large corporate campuses follow the same technical striping standards as any commercial lot. The difference is scale, coordination complexity, and the need for section numbering and access-level delineation. Security clearance and facilities management coordination add project management time but not technical complexity.Should I sealcoat before re-striping my Washington County lot?
Yes. Sealcoating protects the asphalt from rain and UV, and the fresh dark surface makes striping more visible. For high-visibility corporate and retail properties, the combination creates the best aesthetic result. See the sealcoating and striping package.Get Washington County Striping Scheduled
