10 is 3.79 acres for wetland restoration and 1.80 acres for wetland buffer establishment. <br />This would provide a total of 5.59 acres of PVC for drainage area 10. This assumes an <br />approximately 50-foot buffer around the entire wetland. The exact PVC credits for <br />restoring the existing wetland and for buffer establishment within drainage area 10, will <br />be not be determined until a final determination is made as to wetland replacement <br />requirements for the entire RTC project. <br />The primary objective of this restoration would be to remove the non-native reed canary <br />grass and reestablish a diverse, wetland community of wet meadow and mixed emergent <br />marsh. Since portions of this wetland occur on private property, landowner cooperation <br />would be necessary to successfully restore this wetland. The proposed restoration <br />includes both wetland restoration and establishment of buffers. <br />Drainage Area 18 will include a 3.5-acre stormwater pond that will function much the <br />same as the stormwater pond proposed for Drainage Area 7. The concept design <br />described for Area 7 generally applies to Area 18. <br />The wetland system in Drainage Area 19 will function in a way similar to Drainage Area <br />8; that is, it will include a narrow, meandering, perennial stream with a wet meadow/wet <br />prairie fringe. The design concept described for Drainage Area 8 describes this wetland. <br />A total of 1.3 acres of wetland and 1.3 acres of buffer are proposed for Drainage Area 19. <br />Drainage Area 24: This drainage area encompasses a linear area between the Railroad <br />ROW and the RTC. This entire strip of land encompasses some 10.8-acres of land. A <br />total of 2.7-acres, or 1/4 of Area 24, is proposed as new wetland credit. A central, <br />meandering drainage -way of Type 3 wetland is proposed. The edges of this wetland will <br />be bordered with Type 1 and 2 wetland meadow. <br />Drainage Area 26: Development of this combined wetland/infiltration system is <br />conditioned on approval by Anoka County. This system would receive flows from <br />Drainage Area 25 and would include a wetland treatment/stormwater pond (26a). From <br />this initial pond, flows would outlet into an infiltration pond/wetland system (26b). A <br />landscape theme that incorporates a mixture of dry prairie, oak savanna, and wet prairie <br />with an ephemeral water -way could serve as the cornerstone for this area and provide a <br />valuable link between RTC and Mississippi West Regional Park. <br />Off -Site Wetland Mitigation <br />Two additional areas have been identified for off -site wetland mitigation in the event on - <br />site mitigation is not feasible. These sites are illustrated in Figure 12.5. <br />Site #1 would be within the Mississippi Regional Park when development of the park <br />proceeds. Although a specific location cannot be identified at this time, the City, WMO <br />and County would work together to select and develop a site that would hold the best <br />potential for successful wetland establishment. Figure 12.6 illustrates the Anoka County <br />Park Department's concept for how the Park will be designed. Several locations could be <br />possible sites for incorporation of "new" wetland. To accomplish this action in the <br />12-8 <br />
