Rancho Mission Viejo

The Villages of Sendero and Esencia consist of 33 builder neighborhoods entwined with 380 acres of common area landscape including fuel modification, community park spaces, urban farms, streetscapes, and recreation facilities.

The community landscape consists of primarily low and some moderate water use plant palettes with irrigation technologies including centralized irrigation control systems, recycled water supply, drip irrigation, advanced hydrozone planning, and digital as-built and controller chart records.

Santa Clara Square – Commercial Campus

Santa Clara Square is a unique combination of retail, commercial and apartment facilities. The commercial campus includes eleven buildings and three parking structures located within 40 acres of carefully planned, amenity oriented landscape including an existing urban forest of preserved historic Redwood trees.

The site utilizes tertiary treated recycled water for landscape; however higher concentrations of salts and chlorides commonly found in recycled water are intolerable for Redwoods. Due to strict drought regulations, potable water was not permitted for this specialized use for irrigating the preserved urban forest.

Design solutions were provided to construct a customized system to proportionally blend both potable and recycled water sources at a calculated ratio to irrigate the trees within safe sodium and chloride concentrations, but also stay within water allocations.

Excellence in Irrigation 2017 Award Winners

A total of eleven projects were identified as deserving special acknowledgement as examples of unique or outstanding irrigation design challenges and solutions. The submittals were independently judged by a panel comprised of an academic team from Cal Poly Pomona and Kansas State University and peer review.

The Excellence in Irrigation program celebrates the innovative solutions and technical skills required of irrigation design professionals to meet the challenges of designing efficient and effective irrigation in a wide variety of circumstances. Challenges must be unique and the site solutions must successfully address the distinctive climatic, structural, agronomic and system operational needs of each project.

The Historic Estate at Sunnylands

Irrigation design solutions were provided to improve tree health by designing an irrigation system to span the canopies of the tree lines and separating their irrigation from the surrounding golf course. This allowed properly managed irrigation during summer months when the course is inactive.

The trees on the 200 acre site were evaluated and irrigation construction documents were provided in tandem with the golf course renovation. The system was designed to connect to the golf system utilizing HDPE lateral piping at the outer spans of the canopies using a vibratory plow to minimize damage to root systems.

Other design work included irrigation design for the historic residence, guest suites, perimeter streetscapes, and the administration and maintenance facility.

Design efforts received the American Society of Irrigation Consultants Merit Award, 2017.
