The 2010 Standards provide, at section 403.3, that the cross slope of walking surfaces not be steeper than 1:48. The 1991 Standards´ cross slope requirement was that it not exceed 1:50. A commenter recommended increasing the cross slope requirement to allow a maximum of 1/2 inch per foot (1:24) to prevent imperfections in concrete surfaces from ponding water. The Department continues to believe that the requirement that a cross slope not be steeper than 1:48 adequately provides for water drainage in most situations. The suggested changes would double the allowable cross slope and create a significant impediment for many wheelchair users and others with a mobility disability. Accessible Routes from Site Arrival Points and Within Sites. The 1991 Standards, at sections 4.1.2(1) and (2), and the 2010 Standards, at sections 206.2.1 and 206.2.2, require that at least one accessible route be provided within the site from site arrival points to an accessible building entrance and that at least one accessible route connect accessible facilities on the same site. The 2010 Standards also add two exceptions that exempt site arrival points and accessible facilities within a site from the accessible route requirements where the only means of access between them is a vehicular way that does not provide pedestrian access.
