Project Overview
cali

The largest grading project in the world.

Newhall Ranch is the largest master planned development in North America, including roughly 21,500 units situated on 14,000 acres along the Santa Clara River. The project, located in the Santa Clarita Valley, will implement a Net Zero development plan (reducing or mitigating all net greenhouse gas emissions from the project and its construction to zero) by incorporating innovative green building practices, and protecting roughly 10,000 acres of open space.

To maintain the scenic history of this rugged site while developing buildable pads, the Newhall Ranch development will be concentrated within five Villages (Landmark, Entrada, Potrero, Mission, Legacy, and Homestead) which will raise or lower existing terrain by up to 150 feet, and at buildout will move an estimated earthwork volume of roughly 250 million cubic yards.
