Lot 7 (Third Street) Bio-retention Cell

Construction on the Lot 7 (Third Street) bioretention cell began on July 22, 2019. The cell was designed to address surface stormwater run-off from approximately 1.5 acres of the three acre impervious parking lot that empties, via storm sewer, into the Mississippi River. The cell would replace the existing raised median in the parking lot and install permeable pavers around the existing stormwater inlet.

In cooperation with the Muscatine Pollinator Project and the Muscatine Soil and Water Conservation District, the City applied for and was awarded a cost-share grant from the Water Quality Initiative Urban Conservation Project funded by the Iowa Department of Agriculture and Land Stewardship (IDALS).

The bio-cell will channel stormwater through the permeable pavers or into a nine-inch ponding area that will allow the removal of sediment, nitrates, phosphates, and other pollutants from the stormwater before proceeding into the storm sewer. The ponding area will also be home to several native plants that will also aid in the removal of pollutants from the stormwater. Similar plants were used as part of the Mississippi Drive Corridor Reconstruction Project and in the Sycamore Street bio-cell.

The bio-cell will also help alleviate the recurring issues of standing water and flooding of the parking lot and adjacent street.
