... what a pleasure it has been to work with Valley Crest [landscape subcontractor] and Clark. Both companies have been collaboration-focused, and those relationships, which could have been a major challenge, have been a benefit.

With 25 million annual visitors and more than 3,000 permitted annual events, the National Mall in Washington, D.C., is the country’s busiest national park. In 2012, Clark restored over 13 acres of turf and soil on the mall supporting the U.S. National Park Service's efforts to revitalize this heavily trafficked landmark.

Clark installed a state-of-the-art turf system between Madison and Jefferson Drives and Third and Seventh Streets. To begin this process, the project team removed an existing irrigation system. Under the new turf panels, Clark added a drainage and irrigation system that included two large underground cisterns to collect rain water and an underground pump station to reuse the captured water as the principle source for irrigation. The collection of stormwater for irrigation will reduce the use of potable water and help improve regional water quality.

This project is the first of three planned phases, which will ultimately rehabilitate the turf on the Mall from the Capitol to 14th Street.
