Upper Arlington's pre-war and mid-century housing sits mostly on poured or block basement walls, and standard sub-slab depressurization performs well across most of the stock. Mature landscaping and limited interior chase access on the older streets often push the radon stack to an exterior routing rather than up through a closet to the attic. Franklin County's EPA Zone 1 designation and the Devonian bedrock underneath keep elevated readings common across the suburb's full range of building eras. Upper Arlington's eastern border runs along the Olentangy River, separating it from Clintonville and the Ohio State University campus across the water.
