Street Level Map This application is for +/-5,871 if of 8" gravity sewer and +/-1,7571f of 4" PVC force main with a pump station to serve 103 single family residential lots. There is a +/-2681f leg of DIP gravity sewer that is to be installed encased in a 16" steel casing via bore and jack under the wetlands. Manholes on each side are to be greater than 10' from the wetlands edge. The wetwell at the pump station is to be installed greater than 50' away from the wetlands. This project also has a planned 401 & 404 permitted road crossing. Gravity sewer is proposed inside this road crossing. All wetlands on site have been classified by Brown's Environmental Group, Inc as freshwater wetlands WL. Since none of the conditions exist on site requiring 50' separation from wetlands (UWL or SWL wetlands as well as waters classified as WS-11, WS-III, WS-IV, B SA, ORW HWQ or SB), required wetland separation for this project is determined to be 10feet.
