Stormwater Management with Permeable Pavement and Bioretention Structures

Engineering students researched the extent of impermeable surfaces in the east-west portion of North Dodge Street Court and developed a stormwater management plan for the city of Iowa City.

Iowa City was interested in the increased application of permeable pavement and bioretention within the city. These systems fell under the umbrella of “green street” designs, which address growing concern for sustainable stormwater management by mimicking local hydrology prior to development.

The students' plan included recommendations to help the community improve groundwater and runoff quality, reduce runoff quantity, satisfy traditional street and storm sewer design life and expected repair, and improve the quality of life for those living in and nearby the study area. The plan presents three alternatives for increasing infiltration and permeable pavements, each with design plans, cost estimates, and assessments of the options strengths and weaknesses.
