Description:
Stormwater runoff from extensive impervious surfaces in urban and suburban areas has led to human safety risks and stream ecosystem impairment, triggering an interest in watershed-scale retrofit stormwater management. Such stormwater management is of multidisciplinary relevance, posing legal, social, economic, hydrologic, and ecological challenges and constraints. A multidisciplinary approach to stormwater management is being tested in the Shepherd Creek watershed, a 1.8 km2 residential and forested watershed in Cincinnati, OH (USA). Because a majority of total impervious area in sub-watersheds is in rooftops and driveways (50–72%), we decided to use parcel-level best management practices (BMPs) in the form of rain barrels and rain gardens to mitigate stormwater runoff. To abide by laws concerning stormwater, a voluntary economic auction approach will be used to distribute BMPs and evaluate landowners' willingness to accept BMPs on their property in exchange for financial compensation. The hydrologic and ecologic responses to retrofit stormwater BMPs will be tested using a before-after-control-treatment design, where the treatment is the installation of BMPs. This research suggests a policy prescription for retrofit management of stormwater quantity that is, if not ideal in one discipline, at least sound in all disciplines.
