Decomposed Granite + ADA = Not Permitted in COA

June 1, 2011 by Bob Brown

If you are not already aware, the City of Austin no longer allows decomposed granite to be utilized on an ADA route.  Despite what your licensed RAS might say, COA issued an interpretation memo on March 31, 2011 (shown below) stating that “granite gravel” is classified as soft, loose material pursuant to TAS Chapter 4.5.1 and therefore, not permitted.


We encountered this issue on a recent project and just thought we would share with the community in effort to prevent similar issues on your projects.  Feel free to contact us with questions regarding this post, we’d be happy to talk with you.
