ADA Ramps & Compliance in Tonganoxie, KS

A ramp in Tonganoxie passes when the running slope stays at or under 1:12 max running slope, the cross slope under 1:48 max cross slope, the width holds at 36 inches or more, and level landings sit at both ends — the 2010 ADA Standards, checked on the finished slab. Public sidewalk and street ramps follow PROWAG.

Tonganoxie is a rural town turning into an industrial player, and its pavement tells that story in two eras. The historic downtown core runs corners that are fifty years old and older — poured before ADA existed — while the Urban Hess and Tonganoxie business parks put brand-new industrial ground on the map from 2018 forward. The accessible work here lives at that seam: retrofitting the old and getting the new right.

Tonganoxie sits in the loess belt of the Leavenworth corridor — wind-laid silt that holds firm while it is dry and gives up strength when it saturates. On a fresh business-park subbase, that means a landing compacted dry can settle if water works into the loess beneath it, so drainage is part of the ramp, not an afterthought. We compact the subgrade to the right moisture and pitch the grade to carry water off the grade break, so the ground stays firm and the landing stays level. Our soil guide covers how this ground behaves, and the standard carries to ramps in Basehor and Leavenworth.
