At the core of the orchards are 180 acres of planted walnuts, situated a stone’s throw away from the banks of the Sacramento River. Fertile Class II and III soils, solar-powered 100 HP ag irrigation well, and riparian rights to the Sacramento River support a bountiful harvest of walnuts.

There are two large and functional workshops with large roll-up doors, cement floors, shelving, electricity provided by solar panels on the roof, and a lift. Two historical barns remind one of the timeless agricultural traditions of the region.
