ADA Ramps & Compliance in Lee's Summit, MO

An ADA ramp in Lee's Summit, MO passes when the running slope holds at or under 1:12, the cross slope under 1:48, and the clear width at 36 inches or more, with level landings at both ends — the federal 2010 ADA Standards, measured rather than assumed.

Lee's Summit is one of the fastest-growing suburbs in the metro, and a lot of its concrete is new — which sounds like an advantage until the ground underneath it settles. A ramp poured compliant on a fresh subgrade can drift out of tolerance if that base was never stabilized, so getting the landing and the slope right the first time matters more here than almost anywhere.

At the destinations that move the most people — Summit Fair, the Saint Luke's East campus, the school and hospital zones off US-50 — the standard is the whole route, not a single ramp. Someone has to get from an accessible stall across the lot to the door without a slope or a lip stopping them.

We map the path, place the curb ramp where people actually walk, hold the cross slope under 1:48, and set a full-width detectable warning where the route crosses into traffic. At a hospital, that margin is the line between an entrance that works and one that only looks accessible. See related retail and sidewalk work.
