The Seattle City Hall has led the way by implementing a green roof project that has involved the planting of more than 22,000 pots of sedum, fescue, and grass. The City hopes that the project can reduce the annual stormwater runoff for the building by 50 to 75 percent, which will in turn reduce damage to local watershed areas that provide habitats for native species such as salmon. The historic Union Stables building has used green roofs alongside other efficiency based changes to reduce stormwater runoff and decrease the building's energy use by 70 percent. The Park Place building in Seattle's downtown provides a leading example of the use of landscaping to recapture rain water with the hopes of cutting back spending on utilities.
