Beginning in 2007, the Department of Water and Power (DWP) and RAP partnered together on the City Park Irrigation Infrastructure Retrofit Program to upgrade many of the oldest park irrigation systems to modern, state-of-the-art systems. This highly successful program has benefitted many parks, including Ritchie Valens Park, Robert Burns Park, and Lincoln Park. In recent years, many projects have converted existing potable water irrigation into recycled water systems, including the newly refurbished Los Feliz Nine Hole Golf Course, which re-opened in July 2014. Designs are also in process to redo the vast irrigation system for Elysian Park. An important component of this program has been the training and hiring of working age youth, who are provided the opportunity to learn and gain experience in the trades of irrigation and landscape construction.
RAP and DWP also collaborate on turf reduction projects (which all save water) throughout the City, including the new Temescal Canyon Pacific Palisades Native Plant Garden. Here, a former turf area has been transformed into an educational, native plant garden, designed by and under the care of neighborhood volunteers. Collaborative demonstration gardens at Carthay Circle Park in Central Los Angeles and at Dorothy J. and Benjamin B. Smith Park in Hollywood have also recently opened.
RAP works with the Department of Public Works – Bureau of Sanitation and Bureau of Engineering – to implement within the park system many Proposition O (Clean Water Bond Program) projects. These projects help protect water quality, provide flood protection, increase water conservation, provide habitat protection, and create open space. Noteworthy examples include projects located at Echo Park Lake, Rio De Los Angeles Park, Westside Park, South Los Angeles Wetlands Park, and Rosecrans Recreation Center.
