Restriping a Troutdale Lot to ADA Standards
A restripe is the most common moment a Troutdale lot gets brought up to code. Once paint has faded and the lot needs fresh lines anyway, correcting a non-compliant accessible layout costs little more than reproducing the wrong one. For the retail centers and gateway businesses along Troutdale's I-84 frontage, that is the right time to get the accessible stalls right.
This guide covers what an ADA-compliant restripe looks like for a Multnomah County lot and what to verify before the first line goes down. It builds on our statewide Oregon ADA parking compliance guide.
The Compliant Striping Layout
A correct accessible stall is more than a blue box:
- Stall width: at least 8 feet for the accessible space
- Access aisle: 5 feet wide for a car stall, 8 feet for a van stall, painted with diagonal hatching
- Van alternative: an 11-foot stall with a 5-foot aisle is an accepted substitute for the 8-and-8 layout
- International Symbol of Accessibility: painted in each accessible stall to spec
- NO PARKING text: lettered in the access aisle to discourage encroachment
- Aisle placement: level with the stall and connected to the route to the door
Two accessible stalls can share one access aisle, useful across the multi-tenant frontages common in Troutdale retail. For full marking detail, see our 2026 ADA striping requirements and the ADA access aisle striping spec.
Verify the Count and Distribution
A restripe is the right moment to confirm your accessible count is current. The standard is one accessible space per 25 total, scaling up, with at least one in six accessible stalls being van-accessible. In high-traffic Troutdale retail lots, accessible stalls should also be distributed so there is a short accessible route to each tenant entrance, not clustered at one end. Catch count and distribution issues during layout, before paint hits asphalt.
Paint Cannot Correct Slope
Striping makes a lot look compliant, but it cannot fix slope. The 2 percent maximum on accessible stalls and aisles applies to the finished surface. Some Troutdale lots are built on grade near the Sandy River and the Gorge approach, where slope is most likely to be out of tolerance. Before restriping, check the accessible stalls and aisles with a level. If slope exceeds the limit, regrade or patch first. Painting around it hides the problem from your eyes, not from a tape and level.
Paint and Timing in Western Oregon
Western Oregon's wet season and UV fade traffic paint, and faded accessible markings become a compliance gap:
- Water-based latex is the lowest cost and the most common choice
- Oil-based paint adheres better and holds color longer
- Thermoplastic is the most durable option, a strong choice for high-traffic accessible stalls
- Reflective glass beads improve nighttime visibility
Traffic paint needs dry pavement above roughly 50°F to cure, which in Troutdale means late spring through early fall when the rain eases. Booking in spring for early-summer work usually secures better scheduling before the season fills.
Signage Completes the Job
A compliant restripe needs compliant signs. Each accessible stall requires a vertical sign with the International Symbol of Accessibility mounted at least 60 inches to the bottom, a "Van Accessible" plate on van stalls, and Oregon's required fine-amount plate. Replace bent, low, or faded signs as part of the same project rather than leaving a freshly striped lot with non-compliant signage.
Pairing With a Full Restripe
If the whole Troutdale lot is due for fresh lines, fold the ADA corrections into the larger restripe to share mobilization costs. Pricing and seasonal timing are covered in our parking lot striping in Troutdale guide.
The dimensions and specs here are general guidance based on the 2010 ADA Standards and ORS 447.233. Your lot's exact compliance depends on measured conditions, so have a qualified contractor verify dimensions and slope before painting.
