[1] Through the 1960s and 1970s, Hillsdale Shopping Center marked the northern end of a popular Friday night cruise route along El Camino Real for young drivers.

[18][19] Because Target pulled back from the 2013 proposal, which would have reused the existing Sears building north of 31st, it was re-imagined and re-introduced in November 2014.

[20] Also partly in response to public and official feedback, Bohannon presented a modified version of the 2013 plans in February 2015, dropping the idea of building a three-story Target in favor of a bowling alley and fitness center, as the mall sought to be an experiential destination, pivoting away from retail space, in the face of competition from online shopping.

[21] Planning officials asked Bohannon to consider incorporating housing as a mixed-use project, but a spokesman for the company said San Mateo's height restrictions made it unfeasible.

[25] Construction on the replacement North Block buildings, which are planned to achieve LEED Gold certification, was expected to continue through fall 2018.

[26] Hillsdale remained independently owned by the Bonhannon family until late 2021, when real estate firm Northwoods Investors took a stake in the property with the intent of remaking the mall into a mixed-use project.
