Disparate Impact can only be understood with a comparative condition. The Montessori School on Edgewood is in a neighborhood that is 23% White. The sidewalks in front of Thomas Hooker School on Whitney Ave, are perfectly ADA-compliant. It is in a neighborhood that is 62% White.

It is unintentional, of bourse, but intent is not required tor discrimination to exist and the data and evidence says what it says. Brown v Board of Ed. requires that transportation to and from public schools be equal. Sidewalks are a from of transportation. Safe transpiration is not provided equally and that inequality is coincident with the ethnicity of the students.

Department of Services for Persons with Disabilities assigned this issue to City of New Haven Engineering Department

I missed this one last time I visited. It's at the bottom of the access ramp to the fornt door of this public school. It's a little over 2.5 inches.
