[3] In 2022, Alexandria Real Estate completed its acquisition of the site and announced the mall would be demolished and replaced with a biotech campus.

[4] The Tanforan site has been a racetrack, airfield, a military training center, a Japanese American internment camp, a golf course, and a retail complex.

[5] The Western Turf Association acquired 150 acres (61 ha) of land and began construction of the grandstand by September 1899, which was estimated to cost US$35,000 (equivalent to $1,280,000 in 2023) and scheduled to open in time for the season in November.

On January 25–26, 1910, the Tanforan Racetrack served as the site for the Second International Air Meet in America, organized by the Pacific Aero Club and attended by aviation notables Louis Paulhan and John J. Montgomery.

A number of soldiers who were once stationed at camp are buried at the Golden Gate National Cemetery, which is located on a nearby hill that overlooks the Tanforan site.

[18] The mall is bounded by El Camino Real (to the west), Sneath Lane (north), Huntington Avenue (east), and Interstate 380 (south).

[20] By that time, the dated mall was perceived as "dark and ugly" and occupancy had fallen to less than half, although anchor tenants continued to perform well.

The existing stores were closed and the structure was gutted, retaining only the exterior walls, with the exception of the three main anchors (Target, Sears, and J.C. Penney), all of which remained open throughout the major reconstruction.

[21] A two-level Barnes & Noble bookstore and a BJ's Chicago Brewhouse flank the new glass atrium entrance facing El Camino.

[22] The increased sales tax revenue for the city of San Bruno helped to offset the closure of a longtime Ford dealer.

[27] On April 18, 2008, Century Theatres held its grand opening for a new 72,000 sq ft (6,700 m2) 20-screen theater complex at this location, with a skybridge connecting the mall to the new building.

[33] Shifting of consumer shopping practices online due to the retail apocalypse, alongside the COVID-19 pandemic in California, caused a decline in the mall's foot traffic.

[34] On July 2, 2019, a shooting occurred on the upper level of the food court; as a precaution, the mall and nearby BART station were evacuated.

[37] Later that year, retailer Forever 21 went bankrupt and announced plans to close the company's San Bruno location at Tanforan.

[38] As part of JCPenney's 2020 bankruptcy process, the company's store in San Bruno was sold to Alexandria Real Estate for $105 million.
