Sheets 82 and 85 were used for the hydraulic data and overall layout. Sheets 51 -56 provided storm sewer plan and profiles. We propose connecting a 21" RCP, from the Nash Manor Development, into th system along Sandy Lake Road at design point I6b rather than the original desil have recreated the original hydraulic analysis performed by Kimley -Horn, with in Chart 1. We have also provided a hydraulic analysis showing our proposed c design point 16b, with the data shown in Chart 2. The original design provides L8, see sheet 82, into design point I8. Our design proposes 4.49 acres of L8 to point I6b and 2.35 acres of L8 to drain into design point 18. The proposed desil hydraulic grade line of the original system a small amount at design points PI I the system still meeting the City of Coppell design requirements. In our calculations we assume the hydraulic grade line is equivalent to the croN whenever the calculated hydraulic grade line falls below the crown of pipe. In calculations, performed by Kimley -Horn, there are several cases where the call grade line is below the crown of pipe and shown as such. The result is a differ hydraulic grade lines, shown in Chart 1, and the original hydraulic grade lines Kimley -Horn in the Sandy Lake Road Reconstruction Plans. If you have any questions, please call. Sincerel , ryan P. Powell k ftlwi Horn and sewer system storm sewer n point I8.
