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

Restriping an Umatilla Lot to ADA Layout

Umatilla sits on the Columbia River at the heart of northeastern Oregon's industrial corridor, alongside Hermiston and Boardman. The Port of Umatilla, food-processing and cold-storage plants, sprawling data-center campuses, and the businesses serving thousands of shift workers all run large, heavily used parking lots. Hot, UV-intense summers fade striping fast, and constant truck and equipment traffic wears the surface. When the parking lines go, the accessible spaces go with them. A restripe is the moment an Umatilla lot either drifts out of compliance or gets brought fully up to code.

Restriping is far more than refreshing paint. On a large employer lot it is the cheapest opportunity you will get to correct an accessible layout that was wrong from the start, because laying out a compliant stall costs almost the same as laying out a non-compliant one. This guide walks Umatilla owners through an ADA-correct restripe. For the broader rules, start with our ADA parking compliance guide for Oregon.

How Many Accessible Stalls Your Umatilla Lot Needs

Accessible count follows total stall count at roughly one per 25, and Umatilla's industrial lots reach the higher tiers.

Total Spaces	Required Accessible	Van-Accessible Minimum
76–100	4	1
101–150	5	1
151–200	6	1
201–300	7	2
301–400	8	2

At least one in every six accessible spaces, rounded up, must be van-accessible. A 250-stall plant lot needs seven accessible spaces, at least two van. Smaller storefronts follow the lower tiers. Critically, employee parking counts toward the total just like customer parking — a big workforce lot must be provisioned for its full headcount and distributed near the accessible employee entrances.

The Striping Spec: What Gets Painted

An ADA-correct restripe paints to exact dimensions, not by eye.

Stall Dimensions

• Standard accessible stall: minimum 8 feet wide with a 5-foot access aisle
• Van-accessible stall: minimum 8 feet wide with an 8-foot aisle, or 11 feet wide with a 5-foot aisle
• Slope: the finished stall and aisle cannot exceed 2 percent in any direction

Large flat industrial lots are graded for drainage, so confirm slope before painting — a stall on a poorly draining grade can fail the 2 percent rule regardless of the lines.

The Access Aisle

The access aisle is where a wheelchair lift or ramp deploys and is the most-skipped element on industrial restripes. It needs diagonal hatching, must sit flush with the stall, and must connect to an accessible route to the door. Two stalls can share one aisle. Painting "NO PARKING" in the aisle is strongly recommended — especially at plant and port lots where trucks, forklifts, and equipment stage near buildings. Hatch spacing and shared-aisle rules are detailed in our ADA access aisle striping spec.

The Symbol and Markings

Each accessible stall gets the International Symbol of Accessibility, typically white on a blue field, plus blue stall borders as common Oregon practice. The corridor's intense summer UV and heavy traffic scour these markings, so inspect them annually.

Signage Goes Up With the Paint

Pavement paint alone is not enough. Each accessible space needs a wheelchair-symbol sign mounted at least 60 inches above grade to the bottom of the sign, plus a "Van Accessible" plate on van stalls and Oregon's supplemental fine-amount sign. A correct restripe coordinates new paint with compliant signage so the whole stall meets code at once. The 2026 details are in our Oregon ADA striping requirements for 2026 guide.

Why Restriping Is the Right Time to Fix Compliance

Umatilla has plenty of older industrial asphalt striped before current van ratios and aisle widths were standard. When that paint fades to a full restripe, the lot is effectively blank, making it the cheapest moment to:

• Widen an accessible stall that was always too narrow
• Add a missing van-accessible aisle
• Bring a workforce lot up to its full proportional accessible count
• Move stalls onto the shortest accessible route to the entrance

Repainting the old layout exactly just re-locks any existing violations for another cycle. Fixing them during a restripe costs little more.

Climate, Traffic, Timing, and Durability

The Columbia corridor's hot, dry summers and intense UV fade traffic paint quickly, while heavy truck and equipment traffic accelerates surface wear. Water-based traffic paint typically holds 12 to 24 months, but high-traffic industrial lots may see faster wear. The striping window runs late spring through early fall, when temperatures stay above 50°F and the pavement is dry — though the hottest midsummer afternoons can be too hot for ideal application, making early-morning work the better choice in peak summer. Booking ahead helps coordinate around plant shift schedules and production calendars.

What a Compliant Restripe Costs

Striping costs are industry baseline ranges, and real projects often run higher with prep and signage. As a reference, a complete ADA-compliant accessible stall — including the hatched access aisle, the symbol stencil, and proper signage — has been baselined around $200 to $350 per space. Surface condition, signage, and the per-space count on a large lot all drive the final number. Only a site visit gives an accurate figure.
