The Village at Westfield Topanga opens
The Village opened as an open-air center across Topanga Canyon Boulevard from the mall, with Costco as its first operating tenant on September 11, 2015.
scope = context per D3.
Sources give both September 11 and September 18 for the opening; the earlier date is attached specifically to Costco, which suggests a staged opening rather than a contradiction. Worth resolving.
