Z-Best Composting Facility Modifications

Present Land Use
Existing composting facility
Document Description
The proposed project site is the existing Z-Best Composting Facility at 980 Highway 25, which currently operates under a County-issued Use Permit. The proposed project includes modification of the existing composting process from the current windrow method to an aerated static pile process. Z-Best's detention pond #1 would be modified to ensure it complies with water quality protection requirements embedded in state regulations regarding operations of composting facilities, and the existing flood water storage facility would be enlarged to increase flood storage capacity. SR 25 along the site frontage would be widened to allow installation of acceleration and deceleration lanes into and out of the facility entrance, which would be relocated to to become a new fourth leg of the existing SR 25 / Bolsa Road intersection.
