ADA Parking Compliance Audit in Corvallis, Oregon: What to Expect

Why Corvallis Property Owners Order an ADA Parking Audit

Corvallis is the seat of Benton County and home to Oregon State University, so its parking lots carry constant, year-round turnover — the retail along 9th Street and Circle Boulevard, the downtown and Philomath Boulevard storefronts, and the Good Samaritan Regional Medical Center campus. High-visibility, high-turnover lots in a college town are exactly the ones that draw accessibility complaints, and Oregon makes such complaints cheap and easy to file.

An ADA parking compliance audit is a structured, measured review of your lot against the 2010 ADA Standards for Accessible Design and Oregon's accessible-parking law, ORS 447.233. It identifies where your lot falls short before a demand letter or a repaving permit forces the issue — and in the wet central valley, faded markings are one of the most common findings. This guide explains what a Corvallis audit covers, how it runs, and what to do with the report. The statewide rules behind every finding are in our ADA parking compliance guide for Oregon.

What a Corvallis ADA Audit Measures

A real audit touches every element the federal standards and ORS 447.233 regulate. Here is the checklist an inspector runs in a Benton County lot.

Space Counts and Van Ratio

The auditor counts total stalls and checks the accessible count against the federal table — one accessible space per 25 stalls, two for 26 to 50, three for 51 to 75, and up. At least one in six accessible spaces (rounded up) must be van-accessible. Corvallis's medical lots carry heavier ratios: 10 percent of stalls accessible for outpatient clinics, 20 percent for rehabilitation facilities.

Stall and Aisle Dimensions

Accessible stalls must be at least 8 feet wide. Standard stalls pair with a 5-foot access aisle; van stalls need an 8-foot aisle (or the 11-foot-stall alternative). The auditor measures widths, confirms diagonal hatching and the NO PARKING legend in each aisle, and checks that two stalls aren't sharing one undersized aisle.

Slope

Accessible stalls and aisles cannot exceed 2 percent slope in any direction. Corvallis lots near the Willamette and Marys River bottomlands, where soils settle, often drift past tolerance as the base moves over the years. The inspector reads slope with a digital level at multiple points; a visual estimate does not hold up.

Signage

Each accessible stall needs a vertical sign with the International Symbol of Accessibility mounted at least 60 inches from the ground to the bottom of the sign. Van stalls add a "Van Accessible" plate, and Oregon requires a supplemental sign stating the fine for unauthorized parking — a requirement national chains along 9th Street frequently miss.

Accessible Route and Surface

The path from the accessible stalls to the entrance must be continuous, slip-resistant, and free of abrupt level changes greater than a quarter inch. Cracks over half an inch, potholes, and standing water along the route are flagged — and in the rainy valley, drainage-related ponding is a recurring finding.

How the Audit Process Runs in Corvallis

A typical engagement runs in four stages; our detailed walkthrough of how an ADA compliance audit works covers each, and here is the Corvallis version.

1. Scheduling and intake. You share the lot location and any original striping plans. Audits are scheduled for a dry-weather window so slope and drainage can be read accurately — a real consideration in the valley.
2. On-site measurement. The inspector spends one to three hours measuring counts, widths, aisle markings, sign heights, and slopes, photographing every deficiency.
3. The findings report. You receive a written report listing each deficiency, the governing standard, a priority, and a recommended fix, separating low-cost "readily achievable" items from larger work like regrading a stall.
4. Remediation plan. The report becomes a punch list. Most Corvallis lots need restriping and signage corrections; slope or surface failures may need targeted asphalt repair.

To pre-screen your own lot, run it against our common ADA parking violations checklist before the auditor arrives.

What Corvallis Audits Tend to Find

Across Benton County, a few findings repeat. Faded accessible symbols and aisle hatching lead the list — the wet central-valley climate and steady UV wear blue traffic paint within a couple of years, and a symbol you can barely read counts as missing. Signs mounted below 60 inches or missing the Oregon fine plate come next, followed by undersized access aisles, short van counts, slope creep in older bottomland lots, and drainage ponding in the stalls. None are exotic, and most are correctable in a single restriping and signage visit.

The lesson is to audit early and act. A demand letter or a repaving permit that triggers the alterations rule turns a few hundred dollars of restriping into a much larger project on someone else's timeline.

From Audit to Compliant Lot

Once you have the findings, the fix is usually striping and signage work, sometimes with minor surface repair for slope or drainage. Cojo Excavation & Asphalt handles ADA restriping, symbol stenciling, sign installation, and the asphalt repairs that bring slopes and surfaces back into tolerance for Corvallis and Benton County owners.
