Austin City Hall was installed in 2004 and designed to reflect the natural surroundings. The four-story building incorporates local limestone, a cascading waterfall, and nonsymmetrical shapes, all of which emulate the waterways and canyons of Austin’s surroundings. In 2008 it won the Green Roofs for Healthy Cities Award of Excellence for Intensive Institutional Category.
