Abstract

The City of West Union has been selected by Iowa Department of Economic Development as a Green Pilot Community. A major project within this designation is the reconstruction of the downtown business district public infrastructure in a sustainable, innovative, and replicable way. A key component of this project is replacement of the impermeable street and sidewalk surfacing with a porous paver system. This system, along with bio-retention cells in intersection bumpouts and sidewalk planters, will infiltrate, then cleanse and cool the storm water prior to a very slow discharge rate to Otter Creek. The project area will see a 95% reduction in peak discharge rate for a 100 year storm and a 20% reduction in runoff volume. West Union is located within the Otter Creek watershed, a designated cold water trout stream just below the city. Fayette County Soil and Water Conservation District and IDNR consider improvement of the water quality of Otter Creek to be very important. This reconstruction of downtown West Union in a sustainable manner will be the start of an overall Otter Creek watershed improvement project.
