San Bernardino County Declares Local Emergency

San Bernardino County declared a Local Emergency in response to Tropical Storm Hilary on Sunday, August 20. The Board of Supervisors will be asked to ratify the declaration at its next meeting.  The County and other local public agencies have expended significant resources preparing for and responding to the storm, and the county faces the prospect of serious losses once the full impacts of the storm are felt.

During periods of heavy rain, the City of Chino Hills in partnership with Chino Valley Fire District provides a limited supply of sand and sandbags. Since Thursday, the City's Public Works Department helped source and supply sand. Due to the overwhelming demand for sandbags and our resident's diligent efforts to be prepared, the supply of sandbags was depleted. If your property requires significant sandbagging, visit a local hardware store to purchase the necessary supplies.
