After some delays, Mayor Bloomberg, Governor Paterson and Assembly Speaker Silver broke ground today on the next big thing in civic beautification: the East River Waterfront Esplanade and Piers Project. Phase one costs $148 million; the whole thing is supposed to be finished by late 2011. It will run from the Battery Maritime Building to Pier 35, and feature pavilions — we really don’t have many of those, and our best-known one is falling apart — which are supposed to “create concentrated areas for recreation where it is most appropriate,” and “get-downs,” steps in the bulkhead line that lead pedestrians to the water. Also a greenway, bike lane, etc. Oh, and jobs! 400 of them are promised as a result.
