The Advocacy Award of Excellence is given to the coordinated efforts of Preservation Houston, Houston Mod, The National Trust for Historic Preservation, the Houston chapter of the American Institute of Architects, and Houston Arts and Media to save the Harris County Domed Stadium, known as the Astrodome. The campaign began as a response to a 2013 referendum seeking to demolish the dome and redevelop the site and included a multi-faceted approach that utilized social media, engaged the community, and sought to educate the public about the Astrodome’s significance as the world’s first enclosed stadium.
