10. NW Wetland - Sheet 80 shows a~ outlet pipe invert of 863.52. The normal water level <br /> shown on the grading plan and in the model is 862.0 <br /> <br />11. There is a pipe in the model between the WNW Wetland and the Existing Wetland, but <br /> its not shown on the grading plan or the utility plan. <br /> <br />12. Existing Wetland - Sheet 80 shows an outlet pipe invert at 861.00. The NWL shown on <br /> the grading plan and in the model is 860.50. <br /> <br />13. Pond 18/19 - Label size of the outlet pipe on the utility plan. A 45" pipe with a length of <br /> only 100 feet was modeled, please clarify. <br /> <br />14. SW Pond - Outlet modeled as a 54" round pipe and Sheet 82 shows a 60" arch. <br /> <br />15. Pond 29/30 - Outlet modeled as a 54" round pipe and Sheet 82 shows a 60" arch. <br /> <br />16. <br /> <br />SE Pond - Outlet modeled as a 72" round pipe and Sheet 83 shows a 60" arch. Figure 2 <br />from the Stormwater Management Plan shows an outlet from the SE Pond to N77. <br />Should N77 be directed to the SE pond? <br /> <br />17. <br /> <br />The 100-year flood elevations shown on Table 2 of the Stormwater Management Plan do <br />not match the elevations shown on the grading plan. Also, add the flood elevation for <br />County Pond - C. ell 2 to Table 2. <br /> <br />18. <br /> <br />Table 3 of the Stormwater Management Plan indicates the total runoff volume from a <br />2.5" rainfall is 26.6 ac-ft and the dead storage provided is 34.5 ac-ft, however, two areas, <br />the SW Pond and the City Pond, do not meet NURP Standards individually. This will <br />have to be approved by the Lower Rum River Watershed Management Organization. <br /> <br />G:\ComDevXPROJECTS\Landuse\SUBDIVNZ\Town Centerkhakanson comments 8.7.03.doc <br /> <br />-305- <br /> <br /> <br />
