Puyallup City Hall is a
model for sustainable design and planning-renewing the city's urban
core and setting a precedent for future development. A series of
integrated strategies in the new building have placed environmental
stewardship at the heart of Puyallup's transformation into a vibrant
Mithun's team of architects, landscape architects and urban planners championed civic programs, pedestrian connectivity and ecological functions as a single unified concept. Reaching across South Meridian from City hall, a new civic plaza, courtyard and open spaces embrace historic Pioneer Park, long considered Puyallup's town square.
Water conservation takes center stage, as the Puyallup River watershed-an amenity vital to Puyallup's culture and livelihood-is threatened by population growth and current development practices. A demonstration green roof has 3 different levels of efficiency to show the benefit of rainwater management: standard roof, 2-inch roof and 4-inch roof. Rainwater run-off from each area flows into individual vertical cisterns exhibited on the building's facade. A sensor-controlled LED-light system displays the quantity of water in each cistern, which is then released in a visual and auditory cascade to a cistern below the plaza, providing a non-potable source for irrigation.
Puyallup City Hall is 20% more efficient than required by Washington code. The building's top sustainable features purposely engage and educate the public about their role in shaping Puyallup's smart growth future:
