Fresno County is building for the future. New homes, roads, schools, hospitals, water systems, public facilities and commercial projects are moving from plans on paper to work in the ground. That growth is good for families, good for workers, and essential to the long-term strength of the Central Valley economy.

But Fresno’s growth does not happen by accident. It depends on people, investment, infrastructure, and reliable access to the basic materials needed to build. That is why Cemex’s Rockfield facilities matter so much to Fresno County.

Fresno Mayor Jerry Dyer put it plainly in his 2026 State of the City address, telling residents that “Fresno is under construction” and that “collectively, we are building a better Fresno.” He also noted that the city is “building like no other time in our history.” That message should resonate across the region: if Fresno is going to build more homes, safer roads, stronger infrastructure, and a more competitive economy, it must also protect the local supply of construction materials that make that progress possible.

For more than a century, Rockfield has supplied the Fresno region with locally sourced construction aggregates — the rock, sand, and gravel essential to concrete, asphalt, roads, bridges, homes, schools, hospitals, and nearly every major public and private project. These materials are the literal building blocks of the communities where we live, work, learn and do business.

The Cemex Rockfield Quarry

The Rockfield Quarry has helped supply materials for many of the projects that define the Fresno region today, including major highways, airport improvements, medical facilities, schools, colleges, housing developments, and distribution centers. When people drive on local freeways, visit a hospital, attend class, work in a commercial building or see new housing take shape, there is a good chance locally produced aggregate helped make that project possible.

That local supply is especially important now. Fresno County and the broader Central Valley are facing major demands for housing, infrastructure, transportation improvements, and economic development. Meeting those needs will require millions of tons of construction materials over the coming decades. If those materials cannot be produced locally, they will have to come from farther away — increasing costs, truck trips, fuel use, traffic, road wear, and pressure on taxpayers, contractors, and consumers.

Mayor Dyer also underscored Fresno’s renewed focus on housing, noting that the city had regained its Prohousing Designation and that “tens of millions of dollars will become available to this city.” Those dollars can help move Fresno forward, but only if the region has practical access to the aggregates, concrete, asphalt, roads, utilities, and infrastructure needed to turn plans into completed projects.

A dependable local aggregate supply helps keep construction more affordable and predictable. That matters for taxpayer-funded infrastructure, for homebuilders working to deliver attainable housing, for schools and hospitals serving a growing population, and for employers investing in Fresno County.

Rockfield is also an important local employer. Cemex directly employs more than 90 people in the Fresno region through these facilities, providing high-quality, high-paying jobs that support families and strengthen the local economy. Many more contractors, vendors and related businesses depend on the quarry’s continued operation. These are skilled, family-supporting careers that allow workers to buy homes, raise children, support local businesses and build their futures here.

What Cemex Proposes at Rockfield Quarry

The proposed Rockfield Modification Project represents a significant private investment in Fresno County’s future. Cemex plans to invest more than $50 million to modernize operations and responsibly extend the life of the facilities. At full production, the project is expected to support approximately 750 direct and indirect jobs, generate millions of dollars in labor income and provide meaningful tax revenue for local and state public services.

Mayor Dyer’s address also pointed to the kind of public investments already underway — airport improvements, street repairs, downtown infrastructure and Chinatown revitalization. As he said, “great cities have great downtowns.” None of these priorities can move forward without the locally available construction materials needed to build them.

For the business community, this is also about regulatory certainty. Employers and investors need to know that projects can receive a fair, timely and predictable review. Fresno County cannot call for more housing, infrastructure, investment and jobs while making it harder to maintain access to the materials required to build them.

Extensive Environmental Review

Approving the Rockfield Modification Project does not mean ignoring environmental responsibility. The project has been undergoing extensive environmental review, and Cemex has proposed operating within the existing footprint, using modern practices and implementing a reclamation plan intended to restore hundreds of acres as open space, native vegetation, riparian areas, ponds, lakes and wildlife habitat. Fresno County can support responsible resource development while also protecting the San Joaquin River and respecting the public review process.

The choice before Fresno County is about more than one quarry. It is about whether we are serious about building the future we say we want. If we want more homes, safer roads, stronger infrastructure, thriving businesses and good-paying jobs, then we must protect the local supply chains that make those goals possible.

For more than 100 years, Rockfield has helped build Fresno County. With thoughtful approval and continued oversight, it can continue supporting the region’s growth, economy and working families for generations to come.
