The minimum force main size is 4" 16. Please provide the water service connection, and RPBA location. 17. See the following comment from Utility regarding the spillway & lift station access road: "We do also have the discretion to require access during a 100-yr storm. I'm not sure of BFEs in this area with respect to the floodplain and if elevations would work for this, but I know we would be concerned with this spillway potentially washing out our access to the Lift Station. If elevations work out, I think we'd be looking for some concrete reinforced access road/culverts/low water crossing type structure within our road to ensure we'll always have access with larger trucks/equipment... and don't have to worry about getting stuck in a soggy road." 18. The Utility department has expressed their concern regarding the waterline on Greens Prairie Rd might end up being under the pavement after the future expansion of the road. Please relocate the waterline out of the ROW and dedicate a PUE and please make sure that the detention pond's berm does not encroach the dedicate PUE for the waterline. 19. Check sewer Analysis spreadsheet, MH 1303 to MH 1302 is showing 62 lots contribution. 20. Has there been any study done on the creek that's adjacent to the lift station for a 100 year storm event? 21. The time of concentration determined on Apendix A2 does not correspond with the time of concentration used in Appendix Al. 22. The current culvert designs have a Headwater elevation of less than 1 foot clearance with the embankment. Please address this issue. 23. Detention Pond summary is showing a pond water surface elevation of 310.9 feet for clogged condition & top of berm elevation of 311.5 feet. Appendix Cl is showing discharge at up to elevation 311.5 feet. Please address this issue. 24. Please check HEC HMS output summary on Appendix Cl. It does not correspond with the output data from Appendix C2. 25. Regarding the OP request, the Utility department wants to extent the current OP line to tie into the Regal Oaks Drive to prevent the dead end line on Greens Prairie Rd W. This portion would be 100% funded by the city. I can schedule a meeting with Stephen Maldonado Jr. to further discuss this or you may contact him directly.

Please fix Note # 4 regards Etonbury Avenue, 8" Reinforced Concrete Pavement is a minimum. I have attached to this submittal a geotechnical report from CSC Egineering & Environmental Consultants specifying 7"Reinforced Concrete Pavement as constructed with the previous phases. The existing PUE for the force main crossing the common area is shown as 25 feet wide on the final plat, but it is shown as 20 feet wide on Construction documents. Please fix. The label on the Final Plat was a typo. The PUE for the force main is a 20' PUE crossing the common area. Please note that the PUE is 25' when it is parallel to Etonbury. yTPlease provide elevation every 25 feet along the cul de sac. The elevations are shown on the corresponding insets. 12. Waterline W-8 at Station - 40+00 to 42+00 exceeds depths of 5 feet. Please note that lines can't be shallower than 2 feet of depth and that lines that are less than 4 feet are required to be changed to ductile iron pipe with cement stabilized sand backfill. The sections that would not have enough cover over storm sewer lines are fine. The waterline has 4' of cover in all places and exceeds the 5' depth when crossing under the storm sewer pipes and when going under the existing pipeline. The pipeline company requires a minimum of 2' of clearance between the pipeline and the waterline. Please provide encasement for sewer and water line crossing on Etonbury Avenue. Encasements were added for the water line crossing Etonbury. Please note that some bends were moved to accommodate the casing. Sewer line crossings of Etonbury in previous sections of the subdivision were not placed in encasement pipes. Therefore we are requesting that the sewer lines not be placed in encasement pipes. 5. The minimum force main size is 4" The force main is now specified as a 4"line. Please provide the water service connection, and RPBA location. The water service is shown out at Greens Prairie Road. The location of the RPBA is shown in correspondence with the Lift Station drawings. /Y% See the following comment from Utility regarding the spillway & lift station access road: "We do also have the discretion to require access during a 100-yr storm. I'm not sure of BFEs in this area with respect to the floodplain and if elevations would work for this, but I know we would be concerned with this spillway potentially washing out our access to the Lift Station. If elevations work out, I think we'd be looking for some concrete reinforced access road/culverts/low water crossing type structure within our road to ensure we'll always have access with larger trucks/equipment... and don't have to worry about getting stuck in a soggy road." See Note 2 on Sheet 20. The road has a Hot Mix Asphaltic Concrete Surface. The 100-year design storm is pass through the pond outlet structure without any flow over the road. Only if the outlet structure is clogged would flow go across the road and then it will only be 0.2'deep if a 100—year storm would occur. yg. The Utility department has expressed their concern regarding the waterline on Greens Prairie Rd might end up being under the pavement after the future expansion of the road. Please relocate the waterline out of the ROW and dedicate a PUE and please make sure that the detention pond's berm does not encroach the dedicate PUE for the waterline. The waterline has been moved. The values on the Engineer's Estimate have been revised. W. Check sewer Analysis spreadsheet, MH 1303 to MH 1302 is showing 62 lots contribution. This is under the assumption that 60 lots would be serviced by this line from the adjacent property. Lots 8 and 9 are also serviced along this sewer segment resulting in 62 lots. 2 . Has there been any study done on the creek that's adjacent to the lift station for a 100 year storm event? We have not conducted a study of the creek and we are unaware of any studies that have been done. 211. The time of concentration determined on Apendix A2 does not correspond with the time of concentration used in Appendix Al. Some of the small drainage areas that have a minimum time of concentration of 10 minutes are included in Appendix Al but not Appendix A2. y,22. The current culvert designs have a Headwater elevation of less than 1 foot clearance with the embankment. Please address this issue. The culverts were lowered so that the 100-year storm event resulted in a headwater clearance of 1+ foot. Detention Pond summary is showing a pond water surface elevation of 310.9 feet for clogged condition & top of berm elevation of 311.5 feet. Appendix Cl is showing discharge at up to elevation 311.5 feet. Please address this issue. The elevation-discharge table needs a value above the expected maximum water surface elevation so that the water surface elevation can be calculated. The maximum water surface calculated is 310.9. ? . Please check HEC HMS output summary on Appendix Cl. It does not correspond with the output data from Appendix C2. The drainage areas for the post development condition were incorrect in the HEC-HMS model. The model was run with the correct drainage areas and the revised output printed out. 2 copies of the revised summary table from the drainage report and Appendices C1 and C2 are included with this submittal. The revised model produced essentially the same results as previously presented in the report. A.
