Property Description
Rare opportunity to acquire a scenic ranch property with dual-source water located just minutes from the growing community of Brentwood in Contra Costa County, California. Marsh Creek Ranch encompasses approximately 270 gross acres and offers a unique combination of productive agricultural land, rolling rangeland, natural water resources, and elevated homesites with sweeping views of the surrounding foothills and Mount Diablo landscape. The ranch includes approximately 60 net acres of established olive plantings consisting of Arbequina, Arbosana, and Koroneiki varieties, along with 210 net acres of open rangeland currently utilized for cattle grazing. The diverse terrain supports both agricultural production and livestock operations while also providing exceptional recreational and lifestyle potential. Water resources include five (5) agricultural wells and riparian rights to Marsh Creek with lift pump access across Marsh Creek Road, creating a rare dual-source water profile. Irrigation is distributed through single-line drip within the olive orchard. Utilities are provided by PG&E. Multiple elevated locations across the ranch provide ideal settings for the development of a private estate residence, offering panoramic views, privacy, and a scenic foothill setting. Marsh Creek Ranch presents a versatile property suitable for agricultural production, grazing operations, recreation, or a private ranch estate in a highly desirable location within convenient reach of the Bay Area.
