The Institute for Sustainable Infrastructure (ISI) recently awarded two regional infrastructure projects separate levels of distinction within the Envision rating system. The Tarrant Regional Water District (TRWD) of North Central Texas earned the Envision™ sustainable infrastructure rating system’s Silver award for their Line J, Section 1 Pipeline project. The Sun Valley Watershed Multi-Benefit Project in Los Angeles County, CA, has earned the system’s Platinum award which is the highest level attainable in the Envision system.
The Tarrant pipeline was designed by Freese and Nichols, Inc., a charter member of ISI. ISI President and CEO, William Bertera, presented the award to the Tarrant Regional Water District on September 23, 2014. The Envision Silver award-winning project is a two mile, 108-inch diameter pipeline delivering water from the Kennedale Balancing Reservoir directly to the Arlington Outlet, dedicating a significant amount of water demand from the existing pipelines, and allowing the District to meet future demands at the Rolling Hills Water Treatment line, and locations further west.
The Sun Valley Watershed Project manages storm water for the Sun Valley Watershed in Los Angeles County. It provides flood protection, improves watershed health, increases open space and recreational opportunities, and improves wildlife habitat. The project received 67% of the Department’s applicable Envision credits; the most any project has received to date from the Envision infrastructure rating system. It consists of several completed components including Tuxford Green, Sun Valley Park Drain and Infiltration System, Elmer Avenue Neighborhood Retrofit, and the Elmer Avenue Paseo. Other components include the Rory M. Shaw Wetlands Park and the Sun Valley Watershed Upper Storm Drain System and Recycled Water Line, which are in the final design stage. The Valley Steam Plant and the Whitnall Powerline Easement components are in the conceptual design stage.
