Last year, the City entered into a Professional Services Agreement with SWA Group to use the previously approved Grand Park Conceptual Master Plan and provide the City with a Preliminary Plan for the area's Phase 1 development. Services included are a kick-off meeting, refined site analysis, case studies and field trips, and refined design and the preparation of two community meetings, including digital imagery and outreach material.

The Ontario 'Grand' Park is approximately 340 acres with a length of 3.7 miles and encompasses roughly 400 acres, extends over 3-1/2 miles in an east-west direction, and has varying widths anticipated between 280 to 1,600 feet. The Ontario 'Grand' Park is envisioned as a focal point for the region, serving the City of Ontario's recreational and space needs. Phase 1 is approximately 130 acres and occurs within the eastern portion of Ontario Ranch, Grand Park Street to the north, Eucalyptus Avenue to the south, Haven Avenue on the east, and Archibald Avenue on the west.

The Planning Department conducted a virtual community meeting on Thursday, November 5, 2020 and discussed the framework, vision and preliminary design of Phase I for the Ontario 'Grand' Park. A Community survey to solicit input and receive comments for Phase 1 on the Ontario 'Grand' Park was completed. Please see the Downloadable Files Section below to view the results of the Community Survey and view the presentation from the November 5th Community Meeting.
