ADA Parking Striping in Cornelius, Oregon: Bringing Your Lot Up to Code

Restriping a Cornelius Lot to ADA Standards

Cornelius is growing fast along the TV Highway, and well-marked parking matters for the retail, restaurants, and service businesses serving the Tualatin Valley city. New lots are the ideal moment to get accessibility right the first time, while older lots carrying faded, pre-standard striping need bringing up to code. The restripe is where the accessible layout is locked in either way.

With the old lines gone, you can correct an undersized accessible stall, widen a too-narrow aisle, and reposition signs in one pass instead of paying twice. This guide covers what an ADA-compliant restripe involves in Cornelius. For the statewide rules behind it, see our ADA parking compliance guide for Oregon.

Confirm the Accessible Count First

Verify how many accessible stalls your lot owes before painting. Under the 2010 ADA Standards, the count scales with total spaces: 1 accessible stall for 1 to 25 spaces, 2 for 26 to 50, 3 for 51 to 75, 4 for 76 to 100, and one more per additional 50 spaces. At least one of every six accessible stalls (rounded up) must be van-accessible, so a small Cornelius lot's single accessible stall must be van-accessible.

Oregon's accessible parking law, ORS 447.233, adds signage and marking detail beyond the federal floor, so design against both. Our 2026 ADA striping requirements page covers the current marking standards.

Lay Out Fresh Dimensions

On a new lot, lay out to current standards from the start. On an older lot, do not simply trace the existing, possibly non-compliant layout:

• Standard accessible stall: minimum 8 feet wide with a 5-foot access aisle.
• Van-accessible stall: 8 feet wide with an 8-foot access aisle, or 11 feet wide with a 5-foot aisle (16 feet total either way).
• Access aisle: diagonal hatching across the full aisle plus NO PARKING text, level with the stall, connected to a continuous accessible route.
• Slope: finished stall and aisle surface within 2 percent in any direction.

Adjacent accessible stalls can share one aisle between them. Our ADA access aisle striping spec details the hatch pattern, aisle width, and shared-aisle rules.

Symbol, Stencils, and Paint

Paint the International Symbol of Accessibility — white on a blue field — centered in each accessible stall and sized to stay visible when a vehicle is parked. Blue stall borders are common Oregon practice. For paint, standard water-based traffic latex is the usual choice; the Tualatin Valley's wet winters and summer UV favor a durable formulation, and thermoplastic lasts longer where budget allows.

Signs Go in During the Restripe

Striping is only part of the job. Each accessible stall needs a vertical sign with the accessibility symbol mounted at least 60 inches from the ground to the bottom of the sign, positioned to stay visible when a vehicle is parked. Van stalls add a "Van Accessible" plate, and Oregon requires a supplemental fine-amount sign. Install or verify these posts while crews and equipment are on site to avoid a separate trip.

Surface Prep First

On a fresh build, the surface is ready for paint. On an older lot, paint will not bond to a damp, dirty, oil-stained, or crumbling surface, and a deteriorated accessible stall is itself a violation. Before restriping:

• Clean and dry the surface fully — important given the Tualatin Valley's wet season.
• Fill cracks wider than half an inch in accessible stalls, aisles, and routes.
• Confirm no ponding water, which points to a slope problem to fix first.
• Patch potholes and soft spots along the accessible route.

Sealcoating an older lot before the restripe gives a smooth, dark surface that holds paint longer and makes the markings pop.

Timing Your Cornelius Restripe

The Tualatin Valley striping season runs from late spring through early fall, when temperatures stay above 50°F and rain probability drops. The wet winters mean the dry window is the time to act, so book ahead of the summer rush — especially if your restripe ties into a larger paving or development project.
