A copy of any approvals or permits required should be submitted prior to final approval. 1.10. 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. 1.11. The applicant will be required to obtain a Sanitary Sewer Extension permit. A final copy of the permit should be submitted prior to construction. 1.12. The City will be responsible for long term maintenance of the Pond and Infiltration Basins 1& 2.

Per the City obtained WCA approval for proposed wetland impacts due to road construction, the applicant should be required to monitor the non -impacted portions of Wetland 4 for one year after completion of final stabilization. 1.14. Record drawings must be submitted upon completion of the project. If proposed permanent ponds are to be used as temporary sediment basins during construction, as -built survey shots on ponds must be obtained after construction sediment is removed and side slopes re -dressed. Record drawings must also be submitted to MCWD, per the WCA approval for proposed wetland impacts, to ensure no additional impacts are incurred. Final Plat 2.1. Drainage and Utility Easements should be indicated as necessary to cover all shared stormwater management and sanitary sewer facilities. One contiguous easement should be provided over the proposed facilities located on Lots 1 and 2, to cover all piping, ditching, and basins through the outlet connection to the wetland along the north property line. An easement should also be provided for the sanitary service connection to Lot 4. Easement should be 20' wide to provide adequate access for future maintenance. Final Street and Sewer Plan 3.1. The following should be considered regarding the connection to Heritage Lane: a. If the existing cul-de-sac was removed, extensive work may be required to reconnect existing driveways to the new road location, and an existing manhole would be relocated to a green area. Therefore, leaving the existing cul-de-sac largely unaltered, as indicated in the proposed plans, would provide for the least impact to existing residents and the City. b. Bituminous pavement should be saw -cut to full depth at connection to existing to provide clean match lines. Pavement at connection should match existing elevation and section.
