Our stormwater models demonstrated effective flood prevention behind an Integrated Flood Protection System (IFPS). Treatment wetlands, conveyance pipes, and open channels were designed to manage stormwater runoff resulting from the extreme event caused by simultaneous storm surge (Super Storm Sandy) with severe inland flooding (Hurricane Irene). Our firm modeled inland flooding created by the 100-year 24-hour rainfall event occurring during the 100-year storm surge at high tide, in the context of 31 inches of anticipated sea level rise (SLR) by the year 2050. We also proposed salt marsh creation and sub-tidal enhancements at suitable locations around the peninsula, contributing to the development of a project that is self-mitigating under current regulatory conditions.
