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 prelirninag 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, Hydra <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 it 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 &vshng storm sewer pape because there 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 corrrpleted 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 contour, grades andflow arroms =11 be included in the construction documents <br />Pipe slopes are shown on the pre,6minary 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 andproposed roof drainage will be directed to locations of the Duna -Slope french connectiaras. <br />More detailed information will be included in the constmcdon documents for each prao jea.. <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 stoner sewer system for the Fjmiwalk Apartmentspm as inclarcled 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 terra maintenance plans for allpmposed stormwater BMPs will be completed during the construction <br />documentsphase. <br />Staff will review these documents once they have been submitted. <br />
