Project Goal

JCD replaced irrigated lawns with drought-resistant plant species at the Department of Defense Center and the Chapel at Ord Military Community at Presidio of Monterey

Description

In conjunction with the Army’s Water Conservation Campaign Plan, Jacob Construction & Design, Inc. was awarded the task of showcasing for the government innovative solutions for Xeriscaping and Passive Irrigation Systems. With the utilization of cutting-edge technology and the application of unconventional techniques, the end goal was to reduce potable water usage for irrigation by 2% at the Army’s installations throughout the Presidio of Monterey. JCD set out to replace irrigated lawns with numerous drought-resistant plant species (Xeriscaping) at three sites; the Department of Defense (DoD) Center and the Chapel at Ord Military Community (OMC) at Presidio of Monterey (POM). This project also required JCD to design and install low-flow irrigation systems for all Xeriscaping areas and a passive irrigation system for turf at the DoD Center. To help the government optimize water conservation at its Monterey facilities, JCD insured that the new passive irrigation system caught, stored, and filtered rainwater to be used to irrigate the turf. If successful, this project was to provide the blueprint for an aggressive expansion of Xeriscaping and Passive Irrigation Systems for government installations across the nation.

Through the life of the project, JCD fulfilled all requirements for Quality Control, Safety, and Supervision. Given that the project was performed in multiple locations with occupied facilities on site, signage, traffic control, and constant communication with the tenants/base personnel were critical. All concrete enclosures/ forms as well as electrical, demolition, and meter install were performed by JCD’s in-house personnel.

Given this project was design-build, water conservation and waste-water management were the key priorities through the conceptual stage. Through the design process, JCD’s design and construction team worked closely together with USACE and respective environmental authorities to propose an inexpensive infrastructure that would serve multiple purposes of drainage, irrigation, pollutant management and treatment. In the end, JCD proposed, designed plans for, and constructed a water management system utilizing the EPIC technology that utilized a sand-based root zone capillary physics for vertical water distribution and gravity for horizontal and drainage distribution. The EPIC System is expected to achieve 100% efficiency in irrigation, better turf quality and affordable minimal maintenance construction. Direct Comparative studies demonstrated 58% less water needs as compared to sprinklers, and overnight the 2/3-water allocation in outdoor use for desert climates could be reduced significantly, without a change in landscape area, plant species or cultural habits.

SACRAMENTO, Calif. – The U.S. Army Corps of Engineers Sacramento District awarded a $1.4 million contract Aug. 20 to Jacob Construction & Design Inc. of San Luis Obispo to replace approximately 2.8 acres of turf at the Presidio of Monterey with drought-resistant landscaping. Construction is scheduled to begin in spring 2015.

The Corps is also building passive irrigation systems at Presidio under the contract that captures rainwater, reduces potable water demand and reduces storm water pollution.

“Water conservation is very important in California, especially when we are facing drought conditions like we are today,” said Capt. Andrew Boggs, a senior project engineer with the Sacramento District. “Reducing reliance on water is just the right thing to do now and in the long run,” said Boggs.

The U.S. Army Corps of Engineers Sacramento District provides planning, engineering, project management, environmental restoration and construction services to military and civilian customers in parts of eight western states, including California, Nevada, Utah, Arizona, Colorado, Idaho, Oregon and Wyoming.

U.S. Army Garrison, Presidio of Monterey, California

The Presidio of Monterey’s completed three projects in FY 2016 that contribute to an estimated 37% in annual energy savings and more than $600,000 in energy, water and maintenance costs. The Presidio’s 365,000 square foot Building 4385 complex is the installation’s largest facility and highest energy user, housing administrative offices and a large data center. In 2012, Building 4385 consumed 19% of the Garrison’s energy—costing $1.2 million—and almost 7 million gallons of water. The Presidio began plans that year to reduce both energy and water through a multi-pronged approach, including installation of a grid-connected one-megawatt solar array designed to produce 1,600 megawatt-hours annually and a xeriscaping project that converted three acres of turf to drought resistant landscaping and a passively irrigated field. The Presidio also implemented an energy retrofit through a utility energy service contract, which replaced building lighting; refurbished heating, ventilation, and air conditioning systems; and improved the data center’ power usage effectiveness by 33% by reconfiguring servers and power distribution units, and installing a new hot-aisle containment system, lighting, and computer room air-conditioners.
