GSI Planning

In our project funded by NOAA Coastal Storms, we worked with local stakeholders during monthly meetings of the Green Stormwater Infrastructure (GSI) Task Force established by American Rivers, the City of Toledo, and the Toledo-Lucas County Sustainability Commission to advance the knowledge and use of GSI practices. The overall project objectives were to advance strategies for cost-effectively reducing stormwater run-off and to develop achievable county-wide goals for stormwater reduction.

We selected commonplace sites to incorporate green stormwater infrastructure including a multi-family housing unit, a vacant residential property, and a medical office building. We calculated anticipated changes to stormwater flow after GSI implementation at these sites using EPA’s Storm Water Management Model (SWMM). County-wide goals for GSI planning were established by scaling up the benefits from project sites to analogous sites in Lucas County.

In our urban runoff project sponsored by Ohio Sea Grant, the water quality component of SWMM was used to predict annual runoff contaminant loads.  From this mapping, we were able to identify subwatersheds to target the implementation of green stormwater infrastructure in an effort to reduce the contribution of urban runoff to poor surface water quality.
