Site Plan Application #LA18-000034 2635 Kelley Parkway Page 2 11. Extent of removals at connections to existing pavement shall be coordinated in the field with the City prior to any work. Concrete sidewalk removal limits shall be located at a joint. 12. Pedestrian ramps must be provided on the sidewalk adjacent to Kelley Parkway at the connections to the driveway entrances. 13. The Grading Notes must be revised to indicate a minimum 6" topsoil replacement on disturbed green areas. 14. Retaining wall plans must be provided for review and approval prior to their construction. 15. A fence should be provided on walls 4' or greater in height, and details should be included accordingly. 16. Once the sanitary sewer stub is exposed and location, size, and elevation are field verified, layout and design of service connection must be submitted to City for review and approval prior to construction. 17. In order to limit potential for sewer blockages, a grinder pump should be included prior to connection to public sanitary sewer. 18. The hydrant on the south side of the building should be relocated to the south side of the fire lane to minimize potential for issues with falling walls during firefighting operations. 19. The final location of fire hydrants, valves, and fire connections must be reviewed by the Fire Chief. 20. Due to the short distance and drop in elevation, all joints between CBMH 102 and FES 101 should be tied. 21. FES 101 should be relocated to the NWL (+/-1009.0), and the incoming pipe should be installed with minimal slope to maintain the lowest velocity possible and minimize erosion potential. 22. Sump manholes should be included prior to connection to the regional pond or trunk sewer to limit potential transport of sediment to the regional stormwater management system. 23. Due to heavy soils in the area, the applicant should consider installing finger drains at low point inlets (per detail provided). 24. Riprap installed should be Class III per detail provided. Notes should be included accordingly. 25. Signs should be provided for manholes, gate valves, and flared -end sections in the area east of the retaining wall to mark utilities if grass is not mowed here (see Comment 26). 26. The final locations of trees should be coordinated to avoid conflict with utilities. The tree in the island north of the entrance appears to be in conflict with proposed storm sewer. 27. Native vegetation should be indicated in the area east of the retaining wall and adjacent to the regional pond to minimize the need for maintenance or mowing in this area. 28. The Contractor should be required to submit a Site Management Plan prior to work. The plan should outline concrete management, work that will require dewatering, and any other work requiring protective measures to minimize potential for negative environmental impact. 29. The Contractor should be required to submit a Traffic Control Plan prior to work. 30. The applicant will be required to obtain Minnehaha Creek Watershed District (MCWD) approval and permitting. A copy of any approvals or permits required should be submitted conditional to Final approval. 31. The applicant will be required to obtain a General Construction Permit (NPDES) to discharge stormwater associated with construction activity since more than 1 acre will be disturbed. A copy of the permit should be submitted prior to any land disturbing activity. 32. The applicant will be required to submit a Maintenance Agreement for all stormwater management structures and facilities. The agreement should define maintenance responsibilities following completion of project, specify types and frequencies of inspection and maintenance activities, and designate who will conduct inspection and maintenance activities. 33. Record drawings must be submitted upon completion of the project. H:\ORNO\C13115486\z-LA18-000034_2635 Kelley Parkway\2635KelleyPkwy-1_2018-04-09.docx Bolton & Menk is an equal opportunity employer.
