Keep Texas Beautiful is proud to participate in Keep America Beautiful’s Great American Cleanup (GAC), the nation’s largest community improvement program, taking place annually each spring from March through May. To help inspire events in your community, we've created monthly themes. These themed months are not required and any event or project conducted from March 1—May 31, regardless of the focus, will be counted towards the Great American Cleanup and eligible for free supplies. March: Waterways Cleanup Month presented by Dos Equis. Kicks off on the first Saturday in March with the Great Texas River Cleanup. April: Don’t mess with Texas® Trash-Off. The program supports efforts to clear Texas roadsides of litter and includes cleanups taking place April 1-30. May: Parks and Trails Month. Beautify public spaces in your community.
