Parking Lot Striping in Multnomah County, Oregon
Multnomah County is Oregon's most populous county, home to Portland, Gresham, Troutdale, Wood Village, and Fairview. With over 800,000 residents and the state's densest concentration of commercial, institutional, and industrial properties, the county contains thousands of parking lots that need regular striping maintenance. From downtown Portland parking structures to suburban retail centers in east county, the demand for professional striping is year-round.
Portland's maritime climate — mild temperatures, heavy rain from October through May, and reliably dry summers — creates predictable challenges for paint longevity. The sheer volume of commercial pavement in Multnomah County means property managers must plan carefully to schedule striping during the narrow dry season when contractors are in highest demand. Cojo provides parking lot striping throughout Multnomah County.
Portland Metro Climate and Striping Challenges
Portland averages approximately 43 inches of rain annually, with most falling in a sustained wet season from October through May. This prolonged moisture exposure promotes moss growth on shaded lots, keeps pavement surfaces damp for months, and prevents maintenance during the winter. Standing water in poorly drained lots accelerates paint wear and creates liability concerns when markings become invisible under puddles.
The good news is that Portland's mild temperature range — rarely exceeding 100°F or dropping below 20°F — is relatively gentle on paint compared to eastern Oregon's extremes. UV intensity is lower than high desert counties due to more cloud cover. Most Multnomah County lots need re-striping every 18 to 24 months, which is among the longest intervals in the state.
The dry season from mid-June through September is the optimal striping window, but competition for contractor availability during these months is intense given the volume of work in the metro area. Book early.
Key Commercial Areas in Multnomah County
Portland — Downtown and Central City
Downtown Portland's parking structures and surface lots serve office workers, retail shoppers, hospital visitors, and entertainment venues. The Pearl District, Lloyd District, and Old Town/Chinatown all have significant parking infrastructure. Parking structures need floor-level numbering, directional arrows, speed marking, and tight-tolerance ADA compliance. OHSU's Marquam Hill campus and the VA Medical Center require healthcare-grade striping with emergency access and patient drop-off zones.
Portland State University, Portland Community College, and Reed College maintain campus parking lots with student, faculty, and visitor sections requiring clear delineation.
Portland — Eastside Commercial Corridors
SE 82nd Avenue, NE Sandy Boulevard, NE Broadway, SE Powell Boulevard, and SE Foster Road are Portland's major eastside commercial corridors. These dense strips of retail, restaurant, grocery, and service businesses have lots that range from tight 10-space fronts to 200-space shopping center lots. The high-traffic nature of these corridors means paint wears from constant turning movements and daily use.
The Hollywood District, Gateway area, and Division Street corridor have seen significant development, adding new commercial properties with fresh pavement that needs initial striping.
Portland — Industrial Districts
Portland's industrial areas in Northwest, Swan Island, the Central Eastside, and along Columbia Boulevard contain warehouses, distribution centers, manufacturing plants, and trucking terminals. These lots need heavy-duty markings — truck lanes, loading dock approaches, forklift paths, and safety zones — that withstand industrial vehicle traffic. Standard traffic paint is insufficient for these applications.
Gresham
Gresham is Multnomah County's second-largest city with approximately 115,000 residents. The Burnside Road and Division Street commercial corridors, Gresham Town Fair shopping area, and the Rockwood neighborhood's retail district contain significant commercial pavement. Mount Hood Community College adds campus parking demand. Gresham's eastside location receives slightly less rainfall than Portland proper but faces similar climate challenges.
Troutdale, Wood Village, and Fairview
The eastern Multnomah County communities along I-84 include the Troutdale Factory Outlets, Wood Village's Town Center, and Fairview's commercial development along Halsey Street. The McMenamins Edgefield property in Troutdale has large event lots. These communities also serve as gateways to the Columbia River Gorge, adding tourist traffic during summer months.
ADA Compliance in the Metro Area
Multnomah County's urban density and diverse population make ADA compliance critically important. Portland's strong disability rights community and active enforcement environment mean property owners face higher scrutiny than in rural Oregon. The Oregon Structural Specialty Code requirements — one accessible space per 25 total spaces, van-accessible stalls with 8-foot access aisles, signage at 60 inches minimum — are the minimum.
Portland has additional city-level requirements for certain development types, and older lots that have been re-striped without updating ADA layouts to current standards may be out of compliance. A full compliance review during re-striping is recommended. See the striping regulations Oregon guide for detailed requirements.

Best Time to Stripe in Multnomah County
The optimal window runs from mid-June through September. Portland's dry season is reliable, but early June can still see rain and early October brings fall storms. Pavement must be dry with temperatures above 50°F and no precipitation forecast for 24 hours.
Given the high volume of work in the metro area, book your striping project by April to secure a July or August date. Follow a maintenance checklist to coordinate all pavement maintenance during the dry window.
Frequently Asked Questions
How often should Portland area parking lots be re-striped?
Most Multnomah County lots need re-striping every 18 to 24 months. High-traffic retail lots and parking structures may need attention every 14 to 18 months. Portland's moderate UV levels help paint last longer than in eastern Oregon. See the complete striping guide for details.Can you stripe parking structures?
Yes. Parking structure striping requires specialized epoxy-based paints that resist tire scuffing on concrete surfaces. Structure work includes floor numbering, directional arrows, pedestrian crossings, and ADA spaces on each level. Work is typically done overnight when the structure is empty.How far in advance should I book summer striping in Portland?
Book by April for July or August scheduling. The Portland metro area has the highest concentration of striping work in Oregon, and contractors fill their summer calendars quickly. Flexible scheduling or willingness to accept late June or early September dates may offer faster availability.Do Portland lots have additional city requirements beyond state ADA standards?
Portland has specific development code requirements that may apply to new construction or major renovations. Older lots re-striped to current ADA standards may trigger additional compliance requirements. Check with the Bureau of Development Services for lot-specific requirements.Should I sealcoat my Portland lot before re-striping?
Yes. Sealcoating protects the asphalt from Portland's heavy rainfall and provides a fresh, dark surface for maximum striping visibility. The combination extends overall lot life and appearance. See the sealcoating and striping package.Get Multnomah County Striping Scheduled
