10. As shown this plan proposes a dead end in excess of the allowable 700-foot city standard. The new connection must be made out to County Road 40 through Misky Meadows before building will be allowed along Ivanhoe Street south of Station 15+00. 11. All Emergency Overflows (EOF) must be protected with drainage and utility easements 12. All adjacent grading in Misky Meadows effecting backyard drainage, EOFs, etc. must be completed before building construction will be allowed on the parcels in this development. 13. Provide additional detail in final plans showing intersection grades and drainage. 14. Adjacent downstream utilities needed in Misky Meadows must be shown as proposed within this plan. In some instances these ae shown as existing infrastructure on this plan but those facilities are not in place nor have they been reviewed or included in approved plans. 15. Detail the intension of the existing stormwater infrastructure north and west of CB 281. Remove,replace,or modify as needed to provide only needed functioning infrastructure at the end of this project. 16. Standard Plates for pedestrian ramps shall be replaced with current MnDOT plates that meet ADA standards. Red truncated domes shall be used. 17. All sidewalk shall be placed on a 4-inch aggregate base. 18. Standard details for sewer and water services should be modified to identify the curb stop and stubs being installed to the back side of the 10-foot front yard easement. 19. Engineering reserves the right to continue our review and provide additional comments as identified. 20. River Park Third Addition NPDES permit may need to include this development under `common development.' 21. Add pipe capacity and corresponding modeled cfs for all proposed stormwater pipe/routing. 22. A MIDS report is needed. 23. NPDES erosion and sediment control BMPs need to be shown in accordance with infiltration basin requirements. 24. 45' setback requirement for all structures must be met from the OHW. Also, 1' of clearance from EOF and all proposed low openings is required. 25. Label appropriate elevations and EOF details for the two existing wet ponds. 26. A 50 foot natural buffer or (if a buffer is infeasible on the site) provide redundant sediment controls when a surface water is located within 50 feet of the project's earth disturbances and stormwater flows to the surface water. Environmental 27. The flood zone labels are switched for Zones AE and Zones X. Please correct on plans. 28. The wetland along block 9 should have a 45 ft. easement,not 25. The lots should be pushed back at least 25 ft. from the wetland boundary so that the buffer will remain as outlot. The buildable areas should reflect the 45 ft. buffer strip setback easement. 29. The pond on lots 1 and 2,block 9, do not appear to have the 25 ft. buffer easement and buildable areas do not reflect the 45 ft. structure setback. Again,lots should be reduced so that the 25 ft. buffer is in the outlot.This allows for future maintenance access.
