To find all mentions of your competitor’s branded hashtag within a given radius of a store you’ve opened up in a new city, you should:
set up a geo-search stream, filtered by the hashtag AND the desired radius around the geocode for the new store
create a private Twitter List for your competitor and filter the search results by Followers AND branded hashtag
compose a geo-targeted message, filtered by the hashtag AND the desired radius around the geocode for the new store
set up a geo-search stream, filtered by competitor’s Twitter handle AND the city in which your your new store is located
