Sphere of Influence Study

In late 2017, the Chino City Council, after hearing multiple requests for development and annexation of properties within the Sphere of Influence (SOI), directed City staff to develop an Economic Analysis of the SOI. This analysis was required to evaluate four different potential annexation scenarios, and evaluate the budgetary impacts to the City for each scenario, both through revenues received in the form of taxes, and costs incurred in the form of providing services (police, roadway repair, code, enforcement, etc.)

The Public Review Draft of the Sphere of Influence Economic Analysis is now ready. While the SOI Steering Committee will be providing direct review and input to City staff, we encourage the community to review the document and provide comments as well. 

We invite you to review the two documents linked below and to provide your comments in writing to us, either by emailing or mailing it to 13220 Central Ave, Chino, CA 91710.

60 Swarm

The California Department of Transportation (Caltrans) will begin a paving project on State Route 60 (SR 60) on Monday, July 22, 2019 to repair deteriorated pavement slabs from Euclid Avenue in Ontario to the 60/91/215 Junction in Riverside. Caltrans will also begin a bridge project in fall 2019 on SR 60 to replace Pipeline Avenue, Monte Vista Avenue and Benson Avenue bridge structures. The combination of these two projects and two other local interchange projects has been dubbed the “60 Swarm”.
