Has there been any flood modeling done to see if surface runoff/groundwater from the landfill or the Old Norwood Dump migrates away from these areas during heavy rainfall or flood events? Does the water end up in the basements of residences? or in the watershed?

EPA did not perform specific flood modeling in the landfill or dump areas. EPA did review FEMA Flood Frequency maps and data for this section of Darby Creek and did not find any residential area to fall within FEMA designated “Special Flood Hazard Areas.” Portions of the Norwood Landfill do fall within the FEMA defined 100-year floodplain for this area. Section 2.4.2 of the ESI report (PDF) describes topography and the presumed flow of surface water during rain events.
