Palomar Medical Center West - Escondido, California

Located on 40 acres in the foothills of Northern San Diego County, this 175,000-square-foot, 360 bed facility is the new campus of Palomar Hospital in Escondido, CA. The landscape is integrated with the site to provide a sustainable design through the use of sustainable practices, including use of bioswales, extensive use of native plant materials, and a 60,000 square foot green roof. The overall goal in the design of healing environments is to engender a sense of well being within visitors, staff and patients in the environment. Sweeney & Associates, Inc. worked closely with the landscape design team from Spurlock Poirier Landscape Architects to provide an efficient irrigation system to compliment the sustainable landscape.

The irrigation system uses recycled water for all landscaping on the grounds while using potable water only for the green roof / healing gardens. The low pressure recycled water supply required the design of a booster pump station to provide sufficient pressure to the looped irrigation mainline on the site. The irrigation design for the project includes both conventional drip systems in native planting areas as well as drip line tubing systems in more conventional planting areas. Large 2:1 slope areas are irrigated with light application gear driven rotors and MP Rotators. The control system is a central control system featuring decoder style (two-wire) field wiring, master valves, flow sensors, and evapotranspiration sensors located on the site.
