Businesses must also be deemed to have "contributed to the history and/or the identity of a particular neighborhood, community, or the city as a whole." “Austin’s legacy businesses have made significant contributions to our city’s cultural, economic, and historic landscape and patronizing them is the most important thing our community can do to ensure their preservation,” Derrington said in the press release. The month will wrap with an event at Scholz Garten on Nov. 4, from 6 to 8 p.m. Participants with the most stamps will have a chance to win prizes, according to Preservation Austin.
