Today, a scoping session for parts of the Riverside South development in Manhattan will be held today from 6:00 to 8:45 PM at the City Planning Commission located at 22 Reade Street. This portion of the large development, being proposed by Extell Corporation, would occupy West 59th Street to West 61st Street along the Hudson River. A development of this size could mean sweeping changes for the neighborhood; Extell had originally proposed adding a Costco and 2,300 parking spaces to the development, but later backed out. Today’s meeting is a chance to learn more about the project and solicit public opinion.
