The George W. Bush Presidential Library and Museum is in Dallas, Texas on the campus of Southern Methodist University. The grounds of the Center reflect the President and Mrs. Bush’s longstanding commitment to environmental conservation and restoration. The facility received Leadership in Energy and Environmental Design (LEED) Platinum certification for design and construction; the first presidential library and museum to do so.
A 15-acre native Texas landscape park surrounds the museum and library. A network of paths takes visitors through native Texas environments such as Blackland Prairie, Post Oak Savannah, and Cross Timbers Forest. Integrated water harvesting provides over 60 percent of the water needs for the landscape by the recapture of runoff, rainwater, condensate, and cooling tower process water. Water quality is maintained by routing harvested water through bioswales and wetland polishing cells, which contain an elaborate palette of native vegetation. A 400,000 gallon underground open cell cistern discharges polished water into a groundwater infiltration system.
JBC’s innovative water management strategy utilizes leading- edge “smart” irrigation technology and has been calculated to reduce its potable water use by over 70% as compared to the baseline case. The system is automated and regulated through both soil moisture sensing, and real-time evapotranspiration (Eto) rates.
ROLE OF THE IRRIGATION CONSULTANT:
- Provided services under the lead landscape architect
- Collaborated with the Lady Bird Johnson Wildflower Center in Austin, TX
- Prepared construction plans, specifications and details for the irrigation system, including an underground cistern used to collect harvested water
- Provided irrigation engineering and water resource management services, including an extensive water harvesting system which provides over 60% of the supplemental water needs for the landscape irrigation
- Provided site sub drainage design services
- Provided agronomic soil recommendations as part of the ecological restoration of the site. The highly-disturbed, 25-acre urban site required complete ecological restoration and based on self- sustaining biological processes
Extensive site restoration was needed to create a self-sustaining ecological and biological environment to support the native landscape.
Meeting the requirements for Platinum LEED Certification required extensive interdisciplinary coordination of the design team.
