Limoneira Co. has refinanced debt on Windfall Farms, its large San Luis Obispo County real estate development.

Windfall Farms is a 720-acre thoroughbred breeding farm outside Paso Robles. The property is “surrounded on all four sides by wine-grape vineyards and provides a one-of-a-kind development opportunity for a world-class winery,” according to Limoneira’s website. Currently, parcels of at least 40 acres are available, but Williamson Act restrictions expire in 2012, at which time parcels as small as 10 acres can be created for homes with small farms.
