That's a bit of history for SOMA and South Beach ... I used to work there in the late 90's with a dot-com, there wasn't much of a real estate market at that time. The ballpark was built around then and I think the Portside and 88 King (The Towers) was also finished although they began as condos, finished as a rental building and then back to condo sales, as well as the Bay Crest,. The Old Seaman's home was there on Harrison at 1st; and the bridge was still there!
Art Haus moved in about 5 years ago on Brannan ... and started their First Saturday Art Walk a year and a half ago when they noticed there were neighbors walking on weekends. 15 years changes a lot!
