Happy Valley is one of Clackamas County's fastest-growing communities, with newer retail centers, medical and dental offices, and mixed-use development climbing the hillsides east of Portland. Those lots — many built on graded slopes — all carry the same obligation under the Americans with Disabilities Act: provide accessible parking that works for people who use wheelchairs, walkers, and mobility devices. Oregon adds its own requirements on top of the federal rules.
This guide walks through what ADA compliance looks like for a Happy Valley lot in practical terms, so you can find and fix gaps before they become complaints or claims. For the statewide framework, start with our ADA parking lot compliance guide for Oregon.
This is general guidance. Every lot is different, and the only way to confirm your exact obligations is a site-specific survey.
The required number of accessible spaces depends on your total space count, not your square footage. The 2010 ADA Standards set the ratio at one accessible space per 25 total spaces through the first 100, then step the requirement down for larger lots.
| Total Spaces | Required Accessible | Van-Accessible Minimum |
|---|---|---|
| 1–25 | 1 | 1 |
| 26–50 | 2 | 1 |
| 51–75 | 3 | 1 |
| 76–100 | 4 | 1 |
| 101–150 | 5 | 1 |
| 151–200 | 6 | 1 |
Each accessible space has to meet specific geometry:
Slope is the headline issue in Happy Valley. The community is built on hillside terrain, and lots are routinely graded into slopes. A space that holds 2 percent at construction can drift past it as fill settles, and a lot poured on a hill can have one corner just over the line. This is the single biggest local compliance risk, and a digital level reading on each accessible space is the only way to be certain.
Every accessible space needs a vertical sign showing the International Symbol of Accessibility, mounted so the bottom is at least 60 inches above the ground. Van spaces add a "Van Accessible" sign. Oregon also requires a sign stating the fine for unauthorized parking in accessible spaces — the Oregon penalty plate you see beneath the symbol across Clackamas County.
Painted markings count too. The blue symbol in the stall and the hatching in the aisle have to stay legible against Happy Valley's wet winters and summer UV. Our ADA parking sign requirements page covers mounting heights and the Oregon plate.
Compliance does not stop at layout. The surface inside accessible spaces, access aisles, and along the route to your door must stay firm, stable, and slip-resistant:
Happy Valley's wet winters and freeze-thaw cycles work water into cracks, freeze it overnight, and widen the damage by spring. On hillside lots, water runs downhill and can pool at the base of a graded section, accelerating wear in exactly the wrong spot. Prioritize accessible areas in your seasonal maintenance plan, and inspect them monthly through the rainy season.
Routine maintenance — sealcoating, crack filling, patching, restriping existing lines — does not trigger new ADA obligations. An alteration does. If you fully repave, expand, or regrade your lot, you must bring the path of travel into compliance, spending up to 20 percent of the project cost on accessibility if it is not already accessible. On Happy Valley's sloped lots, regrading an accessible space to hit the 2 percent ceiling is often the most valuable part of an alteration.
The practical path is a documented walk-through followed by a scoped plan — usually some combination of restriping to the correct layout, new or relocated signage, surface repair, and regrading where slopes exceed 2 percent, which on Happy Valley's hillside lots is common. Our ADA compliance audit process explains what a thorough review covers. When you are ready to repaint to a compliant layout, our parking lot striping in Happy Valley page covers local restriping.
