10. The proposed 18" FES needs to discharge within the basin sidewall,not short of the basin <br /> within the hillside, also,include energy dissipation according to city standards. <br /> The preliminary plans have been revised to show the proposed 18"FES discharging within the basin <br /> sidewall and energy dissipation via a 4.2'invert drop in the upstream manhole(CB#7). <br /> Ok <br /> 11. Will the existing 18" FES and stormwater system stay on-line or be abandoned? If so,Hydro <br /> CAD needs to be included for this and the basin needs to be cleaned out to original design or <br /> enlarged based on requirements. <br /> The existing 18"FES and stormwater system will be removed and this is shown on the existing conditions <br /> plan.As stated previously, the existing stormwater basin will be expanded based on the current City <br /> requirements <br /> Staff will review these documents once they have been submitted. <br /> 12. The proposed stormwater lines show it tying together at CB #8,provide detail of how this <br /> will work. <br /> CB#8 is proposed to be built over the existing storm sewerpipe because thea is insufficient depth within <br /> the existing system to accommodate the proposed improvements.A detail of CB#8 will be included in <br /> the construction documents. <br /> Staff will review these documents once they have been submitted. <br /> 13. Provide pipe sizing chart report. <br /> Storm sewer suing calculations will be completed during the construction documents phase. <br /> Staff will review these documents once they have been submitted. <br /> 14. Show parking lot contours, direction of flow and grade percentages.Also, show pipe slope <br /> percentages. <br /> As stated previously,final contours,grades and flow arrows will be included in the construction documents. <br /> Pipe slopes are shown on the preliminary plans. <br /> Staff will review these documents once they have been submitted. <br /> 15. Indicate where all roof drainage is being directed to, and not which CB#. <br /> Existing and proposed roof drainage will be directed to locations of the Dura-Slope trench connections. <br /> More detailed information will be included in the construction documents for each project. <br /> Staff will review these documents once they have been submitted. <br /> 16. The city was not able to review the proposed stormwater system for the `proposed 4-story <br /> apartment building' because it is cut off on page C-2, update accordingly. <br /> The proposed storm sewer system for the Riverwalk Apartments project is included in the revised preliminary <br /> plans <br /> The plans do not match calculated hardcover existing/proposed numbers.The discrepancies <br /> need further explanation. <br /> 17. Submit long term maintenance plan for all BMPS. <br /> Long term maintenance plans for all proposed stormwater BMPs will be completed during the construction <br /> documents phase. <br /> Staff will review these documents once they have been submitted. <br />
