ROCKFIELD (Friant)
About
CEMEX owns and operates the Rockfield aggregate (rock, sand and gravel) plant site located on Friant Road just north of Willow Avenue and the quarry site located just south of Lost Lake Park (MAP).
We’re your friends, family and neighbors with Fresno County roots that run at least three generations deep. For the past 100 years, this quarry has provided the greater Fresno region the building blocks of modern life, using locally-sourced aggregate products to create the foundation for local homes, businesses, hospitals, schools, roads and bridges.
Local, public and private projects include the Save Mart Center at California State University Fresno, Chukchansi Ball Park, Clovis Community College and Clovis Medical Center.
What’s more, our operations support living-wage local jobs and generate tax revenue that help fund public infrastructure and services such as schools, roads, police and fire services.
The Plan
Our Vision
- Support local demand for high quality construction aggregate for homes, businesses and public infrastructure|
- Quality jobs and tax revenue for public services
- Environmental restoration and habitat preservation consistent with the San Joaquin River Parkway Master Plan
Overview
In December of 2019, CEMEX filed the Rockfield Modification Project application with Fresno County proposing to modify and continue our operations with a new operational plan that remains consistent with the San Joaquin River Parkway Master Plan.
We believe that our proposal is an economically and environmentally superior plan to the one adopted over 35 years ago. This proposal is consistent with our longstanding practice of being good stewards of the San Joaquin River by working closely with local organizations to protect local habitat and wildlife. To this end, the plan proposes deeper mining but will not expand the boundaries of the current operations.
In addition to operational modifications and new equipment, the plan calls for updating the quarry’s reclamation of the site. Such plans serve as an environmental blueprint for how the quarry will be restored when the quarry’s supply of hard rock reserve is depleted. At that point, the plant and quarry operations will close and the processing plants removed. The sites will be graded and the areas around the ponds will be planted with native vegetation for the benefit of local wildlife, habitat and potential outdoor recreation. The reclamation occurs while mining is actively underway.
See the maps that illustrate what the property looks like today and after the reclamation is complete.
We Welcome Your Feedback
As part of the county’s planning process, an Environmental Impact Report (EIR) will be prepared and made available to the public, as required by the California Environmental Quality Act (CEQA). During this process, the project will undergo extensive environmental review by an independent third party hired by Fresno County and there will be multiple opportunities for the public to submit written and oral comments and to attend public hearings.
We welcome the community’s input and the opportunity to discuss the details of the project with you. Contact us below to provide feedback and to sign up for project updates.
Thank you for considering a plan that reflects CEMEX’s commitment to local jobs, environmental excellence and being a good neighbor.
