UO North Campus June 15, 2018 <br />Conditional Use Permit Stormwater, Sanitary Sewer, and Water Analysis Report <br /> <br /> <br />expected to be capable of serving the <br />majority of the Riverfront area east of the Millrace. Capacity of the public mains and pump station <br />will need to be confirmed with future development. <br /> <br />UO Pump Station (Destination B): A private pump station located just east of Onyx and just north <br /> <br />of the Millrace currently serves the Central Power Station and Planning/Facilities Management <br />areas of the site. This system may be extended to the west for future development west of the <br />Central Power station, but due to topography and limited system depth, additional pumping <br />systems may be required. With future development, the eastern portion the current pump station <br />drainage area (near the Zebrafish facility) may be modified to drain to the Riverfront Pump Station <br />system. Private mainlines upstream from the pump station will be relocated and/or extended to <br />accommodate future buildings and infrastructure. <br /> <br />th <br />East 8 Avenue System (Destination C): This <br /> <br />th <br />sewer line within East 8 Avenue, which currently terminates the <br />th <br />intersection of Hilyard and East 8 <br />th <br />public sewer near the intersection of Hilyard and East 8 <br />ground surface and is not likely deep enough to provide gravity-fed drainage for the proposed <br />building sites. However, extending th public gravity-fed line across the railroad tracks to the <br />proposed roundabout may provide a destination point for future pumped sanitary sewer systems <br />within the westernmost building sites in the Riverfront area. <br /> <br />Broadway / Franklin System (Destination D): This alternative destination point explores extension <br /> <br />of <br />that runs west within Broadway and Franklin. Two potential connection points and boring <br />locations are shown in Drawing C02. This alternative would involve easements and railroad <br />crossings, would likely be explored only if other alternatives are not available. <br /> <br /> <br />WATER SUPPLY <br />Public and private water mains are available within the site south of the railroad tracks, as shown on <br />Drawing C03. Redevelopment south of the railroad tracks will include relocation and/or extension <br />of existing private water mains and services to accommodate the proposed buildings and <br />infrastructure <br />Public water mains are available within close proximity to the proposed development sites at the <br />west and east ends of the Riverfront area. Possible future connection points are shown on Figure 4 <br />and summarized below: <br />Riverfront Parkway System (Connection A): An existing dead-ic (EWEB) main <br /> <br />extends to a point near the south end of the Autzen footbridge. The dead-end main connects <br />nt Parkway and Millrace Drive. <br /> <br />Alder / Hilyard System (Connection B)ic (EWEB) main extending <br /> <br />from Alder to the old EWEB steam plant. This line crosses the railroad tracks north and west of <br />the Alder Street alignment. At the north side of the tracks, the main extends into, or very close <br />to UO property before extending to the west within the railroad right-of-way. Potential future <br />connections could occur at the north side of the railroad crossing or the Hilyard Street right-of- <br />way if access near the railroad crossing is problematic. <br /> <br /> <br /> <br /> <br /> |8 <br /> <br />
