In the spring and summer of 2021, our project team finalized analysis of why an entirely on-land project is not feasible. The challenges associated with constructing our flood protection entirely on-land are detailed within this memo, along with the conclusion that it is not feasible to construct an entirely on-land project that meets our project goals. This memo was first shared with the Climate Coalition of Lower Manhattan (CCLM) on June 11th, 2021 as a pre-read to our 5th CCLM meeting. The findings from this memo were presented to the CCLM at this meeting, and were additionally shared with the public at our third Open House, hosted on June 28th and June 30th, 2021.
