Return to Successor Agency to the Ontario Redevelopment Agency

Project Area 1

Project Area 1

Project Area 1 was the Ontario Redevelopment Agency's initial project area and has now become a focal point of the Ontario Airport Metro Center. Originally blighted and disused, the project area now includes the Ontario Auto Center, City owned Citizens Business Bank Arena, a hub of industrial development including manufacturing and logistics, the Ontario Mills Mall, and Piemonte.

Piemonte at the Ontario Center is the City’s vision for an urban lifestyle center and regional destination venue. Piemonte will raise the standard for future development in the community while also tapping into the rich history of the land. This premier mixed-use neighborhood in the hub of Ontario’s primary business area will cater to Ontario’s changing demographic through quality housing, retail, restaurant and entertainment amenities geared for contemporary families, upwardly mobile professionals and executives.
