This one is a little complicated to describe. It is 4 buildings (A through D) within a park. The sign at West Side Highway (West Side Highway is also called Kern Street and also called Highway 33) at the corner of Cascade Place says West Side Recreation & Park District but that is the name of the organization that administers multiple facilities; the office for it is Building C. Building A (as indicated by the signs) serves for both Activity and the Senior Center. Building B (also as indicated by the signs) serves for both Assembly and the Auditorium. The Recreation Center is Building D.
Due to Covid-19 the district office and the senior center are closed to the public as well as (normally) the remainder of the buildings except for the Recreation Center; it is open at reduced hours. There are lunches served for seniors Monday through Friday and you need a reservation for them.
The complex includes Skate Park and Wrecker Field Complex.
