Umatilla sits on the Columbia River in northeastern Oregon, part of the fast-growing industrial corridor that runs through Hermiston and Boardman in Umatilla County. The Port of Umatilla, food-processing and cold-storage plants, large data-center campuses, irrigated agriculture, and the commercial businesses serving thousands of shift workers give this area an outsized share of big employer lots — and big employer lots carry big accessible-parking obligations. Add the steady visitor traffic to McNary Dam and the river recreation areas, and Umatilla's parking demand is far more industrial and varied than its population alone suggests.
For Umatilla business owners, plant and warehouse operators, and the employers running large workforce lots, accessible parking compliance is both a legal duty under the Americans with Disabilities Act and Oregon law, and a practical service to employees, customers, and visitors with disabilities. This guide is a 2026 overview of what compliance requires under the 2010 ADA Standards and Oregon's accessible parking statute, ORS 447.233, with attention to the large-lot and hot-dry-climate realities of the Columbia corridor. It complements rather than repeats our statewide ADA parking compliance guide for Oregon.
Required accessible spaces scale with total lot capacity at roughly one space per 25 — and Umatilla's industrial and data-center lots push into 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 |
| 401–500 | 9 | 2 |
A critical point for Umatilla: employee parking counts toward the total exactly like customer parking. A large workforce lot at a food-processing plant or data center serving hundreds of shift workers needs its full proportional accessible spaces, distributed near the accessible employee entrances.
Accessible stalls and their access aisles cannot exceed 2 percent slope in any direction on the finished surface. The accessible route from parking to the entrance cannot exceed 5 percent running slope and 2 percent cross slope. Large flat industrial lots are graded for drainage, and ponding water in an accessible space signals a slope problem that the corridor's heavy rains can expose.
Every accessible stall needs an access aisle marked with diagonal hatching, kept flush and level with the stall, and connected to an accessible route to the entrance. Two stalls may share one aisle. No vehicle may park or stand in an aisle — a real discipline issue at plant and port lots where trucks, forklifts, and equipment stage near buildings.
Each accessible space needs a vertical sign with the International Symbol of Accessibility, mounted so the bottom of the sign sits at least 60 inches above the ground and stays visible over a parked vehicle. Van-accessible stalls add a "Van Accessible" plate. Oregon requires a supplemental sign stating the fine for parking illegally in an accessible space. Our guide to ADA parking sign placement in Oregon covers mounting height and the Oregon fine plate.
ADA compliance extends to surface condition. The accessible route from stalls to entrance must stay free of:
The Columbia corridor's hot, dry summers fade paint with intense UV, while heavy truck and equipment traffic at industrial lots accelerates surface wear and rutting. Prioritizing accessible areas in maintenance keeps them compliant.
Routine maintenance — sealcoating, crack sealing, patching, restriping existing markings — does not trigger new ADA obligations. But a full repave or significant reconstruction counts as an "alteration," obligating you to bring the path of travel into compliance to the maximum extent feasible, up to 20 percent of the project cost. For Umatilla's large industrial lots, where repaving is a major investment, auditing first lets you fold compliance into the same project. See our overview of the ADA compliance audit process.
Across the corridor, a few issues recur on large employer lots:
Most are inexpensive striping and signage corrections; slope, drainage, and route grading are the larger items.
Compliance work is priced as a range, and actual costs depend on condition and scope. A complete ADA-compliant accessible stall — symbol stencil, hatched aisle, and signage — has been baselined around $200 to $350 per space. Signage runs roughly $100 to $300 per sign installed. Slope correction, drainage, and route repair are larger, variable line items, and a big industrial lot multiplies the per-space count. A site visit is the only way to get an accurate figure.
