Summary, model-written

Shops at Tanforan (San Bruno, CA) is a proposed redevelopment of a former mall site. The original site was a horse racing track (1899–1964), later used as a WWII internment center.

It is listed as 'proposed' with no construction status noted.

Where it stands. No active retail tenants listed in EDGAR filings. Retail establishments declined 11.3% (2012–2023) in the county. Traffic data shows high volume (160k ADT) on Interstate 380 nearby.

Background

The Shops at Tanforan is a regional shopping mall in San Bruno, California, United States. It is located on the San Francisco Peninsula, 10 miles (16 km) south of San Francisco city limits. The site was originally used as a horse racing track from 1899 until 1964, when the grandstand was destroyed by fire. During World War II the track was used as the Tanforan Assembly Center where Japanese American citizens, primarily from the San Francisco Bay Area, were interned until more permanent War Relocation Centers were opened. A shopping mall was built on the site and opened in 1971. The mall underwent a 3-year renovation, and reopened in 2005.
