[11] Due to extensive damages to the school during the 1949 Olympia earthquake, the building was razed and the park became public.

[12][13][14] A memorial bench in the park was dedicated in 2007 to Gavin Crandell, a sixteen year-old who died the prior year after being struck by a train at a crossing 0.5 miles (0.80 km) away.

Considered the first of potentially three phases of renovations, the $115,000 total funding is to aid in the purchase of new playground equipment, the construction of a perimeter fence, and to upgrade the sidewalks and parking areas to be in compliance with the Americans with Disabilities Act (ADA).

[17] The welcome sign to the neighborhood, located in a traffic calming roundabout directly east of the park at the intersection of West and Pennsylvania, was destroyed in a hit-and-run incident in December 2023.

[18] Westside Park is unable to qualify for listing with the National Register of Historic Places (NRHP) due to a loss of records during a 1910 fire at the defunct West Side School.
