The road surface and gutters will be completely removed as part of road reconstruction on 27th Avenue NE, Pahl Avenue and Roosevelt Street. The excavation for the other utilities and the subgrade excavation required for the street reconstruction provides a timely opportunity for improvements to the water distribution system before significant problems are experienced. The proposed watermain improvements consist of replacing the existing 6 -inch cast iron mains on 39th Avenue NE, Roosevelt Street, Pahl Avenue and 27th Avenue NE with new 8 -inch ductile iron pipe (DIP) main. This will, improve delivery of potable water and fire flow volume at reasonable pressure and head loss. Replacement of the service taps and lines may improve the water quality by reducing the potential for lead to enter the system and possibly increase the pressure by providing a clean service pipe. The proposed water system improvements are shown on Figures 6 and 7 in Appendix A. 4.3. Storm Sewer The proposed storm sewer improvements include replacing the existing storm sewer on 39 th Avenue NE running from Penrod Lane to the railroad crossing at Fordham Drive with the addition of new catch basins at each intersection. 2007 STREET AND UTILITY IMPROVEMENT PROJECT FEASIBILITY REPORT CITY OF ST.
