La Grande sits at roughly 2,800 feet in the Grande Ronde Valley of Union County, ringed by the Blue Mountains and anchored by Eastern Oregon University. Between the campus, the historic downtown along Adams Avenue, and the businesses serving Interstate 84 travelers, the town's parking lots see steady year-round use. Every lot open to the public carries the same obligation: accessible parking that meets federal and Oregon accessibility law.
ADA compliance applies to nearly every business open to the public and does not expire. The 2010 ADA Standards for Accessible Design set the federal baseline, and Oregon adds its own requirements through ORS 447.233 and the Oregon Structural Specialty Code. This guide walks La Grande owners through the core requirements so you can evaluate your own lot before a complaint or a survey forces the conversation.
For the statewide framework behind everything below, start with our ADA parking compliance guide for Oregon.
The number of accessible spaces is set by your total parking count, using the 2010 Standards ratio of roughly one accessible space per 25 in smaller lots.
| Total Spaces in Lot | Minimum Accessible Spaces |
|---|---|
| 1–25 | 1 |
| 26–50 | 2 |
| 51–75 | 3 |
| 76–100 | 4 |
| 101–150 | 5 |
| 151–200 | 6 |
| 201–300 | 7 |
Each accessible space has to be built and striped to specific dimensions:
The 2 percent slope limit matters in La Grande because the high-valley freeze-thaw cycle works on pavement all winter. Ground that freezes and thaws repeatedly heaves and settles, and an accessible space that was within tolerance when paved can drift out of it after a few hard winters. Slope should be measured rather than assumed.
Every accessible space needs a vertical sign showing the International Symbol of Accessibility, mounted so the bottom sits at least 60 inches above the ground. Van spaces add a "Van Accessible" sign. Oregon also requires a supplemental plate stating the fine for unauthorized use — a detail many out-of-state sign kits leave off. Our guide to ADA parking sign placement and mounting covers heights and sign types.
The painted accessibility symbol in each space matters too, and faded symbols count as a compliance gap. High-elevation UV exposure plus winter sanding and plowing fade and scrape paint quickly in La Grande, so markings may need refreshing more often than in milder climates.
Grande Ronde Valley winters are cold and snowy, with real freeze-thaw cycling and the sand and plow blades that come with keeping lots usable. That combination widens cracks, heaves surfaces, and abrades paint. Cracks over half an inch and any pothole inside an accessible space, aisle, or route are violations; standing water from spring melt that ponds in an accessible space signals slope or drainage out of tolerance. Prioritize accessible areas first every spring, because high-valley winter damage is significant and predictable.
Routine maintenance — sealcoating, crack filling, restriping existing lines — does not trigger new ADA obligations. A full repave, overlay, or regrade is an "alteration" under the ADA, which obligates you to bring parking and the path of travel up to current standards to the maximum extent feasible. Because La Grande's freeze-thaw forces repaving more often than milder climates, those repaves are recurring opportunities to bring accessible spaces back into slope and surface compliance.
Count your spaces and compare against the table. Walk the accessible spaces and check sign height, the fine plate, the symbol paint, the aisle hatching, and look for ponding, heaving, or cracks. Measure slope where you can, and recheck it every few years given the freeze-thaw cycle. If you are restriping after a sealcoat, that blank surface is the ideal time to correct the layout.

This is general compliance information, not a legal determination for your property. The reliable path is an on-site survey by a contractor who measures your lot against the current standards.
