The project utilized a highly efficient, automatic irrigation system that provides a subsurface drip irrigation method to each shrub, succulent and groundcover, with the irrigated area limited to within the root zones of the plants.

The irrigation system is controlled electrically with a satellite irrigation control system and communicates with the Base’s irrigation central control system. The irrigation system included design elements and equipment to minimize damage to key components, such as sprinkler heads, controllers, control valves, valve boxes and the backflow preventer.

The MCAS Yuma project has a 150,000-gallon irrigation water parameter. The planting design along with the efficient irrigation system design will stay below that parameter and after four years post installation the Irrigation system will be reduced to 39,159 gallons per year.

The scope of the landscape design included elements to make the outdoor environment more sustainable, comfortable, pleasant and safe, achieve AT/FP setbacks, screen unattractive uses, provide wind protection and a variety of shade methods for relief from extreme heat. These included landscape and rock mulches for erosion control, drought tolerant/native containerized planting for the building entry, plaza, perimeter/interior and streetscape landscape.
