Sphere of Influence

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 SOI@cityofchino.org or mailing it to 13220 Central Ave, Chino, CA 91710.
