In 2003 the City delineated these wetlands and completed a wetland mitigation strategy for replacement of impacted wetlands. Several of these wetlands may be impacted without mitigation since they are considered excavated storm water ponds. However, 3 historic wetland areas are still subject to mitigation, shown in Figure 7 in Appendix B and Appendix D. "Wetland 1"located in the northwest corner of The COR, is a remnant historical wetland that has not previously been mitigated. "Wetland 2" located directly adjacent to Wetland 1,is a mitigation banking site constructed to mitigate impacts occurring from the Bunker Lake Boulevard Improvements,therefore can be treated as a historical wetland. A portion of "Wetland 7"located in the northeast quadrant of Sunwood Drive and Zeolite Street, is a remnant historical wetland that has not previously been mitigated. Jurisdictional Authority/Approvals/Permits As the project moves from the planning stages to design and construction,permits will be required from various agencies. Understanding and planning for requirements associated with obtaining permits and approvals at this time will be critical to the ultimate success of the process. The following agencies will be permitting entities for considered improvements: • Minnesota Department of Transportation(MnDOT) State Aid: Sunwood Drive NW,Zeolite Street, Veterans Drive from Zeolite Street to Ramsey Boulevard, Rhinestone Street from Veterans Drive to Bunker Lake Boulevard, and Center Street from Sunwood Drive to Bunker Lake Boulevard are State Aid routes, • Minnesota Pollution Control Agency(MPCA): NPDES Storm Water Permit, • Metropolitan Council Environmental Services (MCES): Sanitary Sewer Extension Review, • Minnesota Pollution Control Agency(MPCA): Sanitary Sewer Extension Permit, • Minnesota Department of Health(MDH): Watermain Extension, • Department of Natural Resources (DNR): Dewatering, • Lower Rum River Watershed Management Organization: Storm Water. Timing of Improvements While the improvements discussed and depicted in the figures will be required to support the area, timing of the improvements will most likely be dependent upon each proposed development. As individual developments are considered, the public infrastructure will need to be reviewed and determinations made as to its adequacy to serve the properties. As upgrades, extensions and improvements are determined to be necessary, funding strategies will need to be developed which may include full or partial assessments to benefitting properties. Vill. DESIGN SUMMARY While there is a general understanding of the total public improvements required to serve the area, sequencing of the improvements will allow for planning and fiscal responsibility. Our understanding of the most likely individual segments to be developed are shown in Figure 2 in Appendix B, and include: • Ramsey Parkway-Segments A-1 and A-2 o Extension of Ramsey Parkway from Willemite Street NW to Sunwood Drive Roundabout. ■ Two 24-foot one way roadways o 6-foot concrete sidewalks on the north and south sides Prepared by:Bolton&Menk,Inc.
