About Casitas Valley Growers: Casitas Valley Growers was a nested enterprise within the larger Casitas Valley Farm while it existed (late 2013 to late 2018). CVG developed a 1/3rd acre regenerative market garden in an old barren field, ultimately totaling 72 raised beds on contour in 5 separate paddocks and a 2000 square foot high tunnel. CVG supplied local restaurants in Carpinteria, Ventura, Ojai and Santa Barbara with salad mixes, herbs, microgreens and mushrooms as well as seasonal fruit from Casitas Valley Farm. Casitas Valley Growers was built and operated by Casey Pfeifer (thats me) and Jesse Smith, now the head Land Steward at White Buffalo Land Trust.
Design Elements
- Market garden design around a passive water harvesting earthworks systems consisting of three linked swales that served to divert and infiltrate run-off from an existing erosion gully and repattern it across the field. Swales were planted to a backbone of fruit trees and other perennial crops with annuals interspersed between them on a seasonal basis.

Swale after first rain event. 
Swale filled almost to capacity just below armored level sill spillway.
- Vehicle access around the perimeter and through the garden underneath the uppermost paddock and top swale in the system for efficient movement of material.
- Produce was grown in 30″ wide raised beds laid out on contour following the three swale lines. Pathways varied in width from 18″ to 42″.
- Automated irrigation system built to service the 5 paddocks, interstitial swale lines, hoophouse, nursery and mushroom propagation area.
- 2000 square foot hoop house constructed and used to grow in-ground crops, microgreens and vegetable starts for the rest of the market garden.
