The Pond Project includes water quality terraces, a stormwater wetland and wetpond, a stepped rock swale, and over 10,000 plants including aquatic trees, vigorous shrubs, native grasses, and numerous flowering specimens that will provide improved water quality and beauty year round.
The project is designed to filter, store and treat runoff from the original Museum as well as the newly-opened 70,000 square foot Gallery Expansion, designed by Thomas Phifer and Partners, and all of the parking, garden and plaza spaces. This was a tall order for the original stormwater pond, constructed in the early 1980's. Changes in stormwater management standards since this time, and the existing site infrastructure required a new approach.
The pond project retrofits the existing site and storm sewers to work in a new way; to direct stormwater to surface drainages, to spread runoff out instead of concentrating the flows, and to provide contact with soils and vegetation. The design also reveals the inner workings of the storm drainage, allowing for visitors to observe the flow of stormwater runoff, and its treatment in the swales, terraces and wetland.
