Floodplain Review Letter (2) October 14, 2016 Wayne Feiden Director of Planning and Sustainability City Hall, 210 Main Street Northampton MA 01060 RE: Proposed Bench, Ward Avenue Mill River Trail, Parcel 31C-036 Dear Wayne: Thank you for contacting the Commission regarding a proposed bench in the floodplain along the Mill River Trail. Elevation data for the exact location of the bench is not available, so staff has assumed that the entirety of the bench will be located within the floodplain. Based upon the Dumor construction specifications, even if the bench were a solid block, it would only alter 22 cubic feet of compensatory flood storage. The Northampton Conservation Commission voted that projects impacting less than one cubic yard of bordering land subject to flooding do not "cause an increase in or... contribute incrementally to an increase in the horizontal extent and level of flood waters during peak flows," so no additional floodplain review is necessary. As you know, the bench area is located within riverfront area. A Request for Determination hearing regarding riverfront area work will be scheduled for the October 27 Conservation Commission meeting.
