Developers of the mixed-use development at the former Seaholm Power Plant announced Wednesday the sale of the properties in the 5-acre downtown site. A story in Community Impact Newspaper's May edition detailed the progress that had been made at the development, which is bounded by Cesar Chavez Street, West Avenue, Third Street, Seaholm Drive and Union Pacific's Austin Western Railroad line. The 126,000-square-foot Seaholm Power Plant was originally built in the 1950s. The city of Austin decommissioned the plant in the 1990s and then hired Seaholm Power LLC in the 2000s to redevelop the site. The property now includes such tenants as Athenahealth, Boiler Nine Bar + Grill, True Food Kitchen and 280 condominium owners. Seaholm Power LLC also announced today the closing out of condo sales at Seaholm Residences.
