New Construction program in 2004 and later Platinum Certification under LEED-EB (LEED for Existing Buildings) in 2007. The library's flooring is made of recycled rubber tires and there are charging stations for electric vehicles in the parking lot. In 2007, a rooftop garden was established atop the library, in addition to existing solar panels. The garden collects runoff and is maintained without the use of gasoline-powered lawn mowers and chemical pesticides or fertilizers. Economic impact After the location for the project was announced, many new businesses began to develop in the surrounding area. Numerous hotels, restaurants, housing complexes, offices, retail stores were established. The revived River Market district, a dining and retail area near the library, was created as a result of its location. In addition, over $1 billion of new real estate has been invested in downtown Little Rock. The world headquarters of Heifer International is located just beyond the library. The center has spurred an estimated $2 billion in new projects in the surrounding parts of Little Rock. Since its opening, the library has had over 1.64 million visitors. The museum had 302,583 visitors in 2009 and 273,108 visitors in 2008. There were approximately 500,000 visitors during its first year (November 2004 – 2005).
