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 the site. A significant constructed wetland acts as a functional as well as educational purpose – filtering all site runoff while telling the story of wetland prairie function. 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.
