The Southern Manhattan Coastal Protection Study: Evaluating the Feasibility of an MPL report (the “Feasibility Study”) was conducted by a team led by ARCADIS U.S., Inc.. The team also included HR&A Advisors, Inc., FXFOWLE Architects, WXY Studio, Sive, Paget & Riesel P.C., AKRF, Inc., Ocean and Coastal Consultants, and Jesse M. Keenan (the “Study Team”). The Feasibility Study focused on an approximately 1.3-mile span of the eastern edge of Manhattan, from the Battery Maritime Building to Pier 35 (the “Study Area”). The Feasibility Study also analyzed adjacent areas that would be integral to a comprehensive flood protection solution for Southern Manhattan. The Feasibility Study concluded that: 1) An multi-protection levee (MPL) is technically feasible in the Study Area and will not induce flooding either in adjacent neighborhoods or across the East River. 2) An MPL is legally feasible within the existing regulatory framework. However, the required permitting/approvals processes will be complex and lengthy. 3) An MPL is financially feasible and could not only be self-financing, but could also help finance complementary flood protection investments in Southern Manhattan. The MPL options and conceptual development programs evaluated within the report were defined for feasibility analysis purposes; the findings within do not comprise a development proposal. The process to articulate, assess, and advance an actual development proposal for an MPL will be long and complex, and will require extensive local stakeholder engagement and coordination. The commitment to effectively address the known climate change risks must remain as the core driver of that process, especially regarding all future work that builds upon and follows up on this Feasibility Study. https://doi.org/10.5281/zenodo.5246133
