Green Stormwater Infrastructure Investment Model For Philadelphia’s Wingohocking Sewershed

Municipalities are turning to green infrastructure (GI) as an attractive solution for combined sewer overflow (CSO) control. Given the myriad combinations of GI implementation options, decision makers need tools to optimize investments. Multiobjective models hold significant promise for developing GI investment portfolios, but need to be developed and tested under real world conditions. We present models for estimating GI costs and for optimizing deployment of GI practices applied to a Piedmont sewershed in Philadelphia’s CSO area
