An example of environmentally sensitive design on a large scale, the EWEB Roosevelt Operations Center integrated an existing wetland prairie into its overall plan. As such, storm water control and pollutant filtration take center stage in the design of this site. A significant constructed wetland acts as both functional and educational – filtering all site runoff while communicating the role wetland prairies play in our world. The public spaces surrounding the building are also part of the strategy, with roof drains flowing into the plaza planters, and a living wall adding a colorful focal feature. The wetland mitigation planting area includes features such as emergent and vernal pools, island habitat for the endangered Western pond turtle, shrub and forest planting, pedestrian outlook areas, and grassy stormwater swales.
