magnitude and duration. Currently, row cropping occurs into the wetlands. The RTC <br />will incorporate wetland buffers wherever practical. <br /> <br />Wetland Replacement: The LRRWMO Stormwater Management Plan provides that the <br />following may be eligible for wetland replacement credits: <br /> <br /> · Creation of"new" wetland - Rules, Sub-part 11; <br /> · Addition of"public value" Rules, Sub-part 6; <br /> · "Public value" restoration from invasive species to permanent native, non- <br /> invasive species - Rules, Sub-part 8; and <br /> · Incorporation of"water quality treatment ponds" under the criteria <br /> contained in Sub-part 10(A* and B), with nature of"credit" determined by <br /> LRRWM©. <br />· The City of Ramsey has adopted the £RR WMO stormwater management plan by <br />reference for this portion of the City, thus q~talifi,,ing the City for eligibility under this <br />element. <br /> <br />As Table 12.2 shows, a total of 6.94 acres of wetland will be impacted and require <br />replacement. A central feature of the RTC is a ~eenway corridor rurming though the <br />central portion of the site. A system of stormwater ponds, infiltration swales and <br />meandering channels will link flows entering the site from the northwest with flows <br />generated on-site. This "waterway" will continue south from the RTC to the Mississippi <br />River. Within the context of this ycaterway system, on-site wetland replacement will be <br />provided though a combination of new wetlands, upland buffers and water quality <br />improvement ponds designed to improve functions and values to downstream wetlands. <br />The location of proposed on-site wetland replacement is shown in Figures 12.3 and 12.4. <br />Table 12.3 summarizes the acreage and type of wetland replacement for each location. A <br />general description for each wetland replacement site follows. <br /> <br />Table 12.3 Summary of Proposed Wetland Mitigation <br /> <br />· .Wetland : .... i: Wetland Replacement by Location (Drainage Area) : '.TOtals... <br /> <br />5'Created ::: :: 6 I 7 I 8 ] 10 [.. 1. 18-19 124 26a [ 26b : :'(acres):::'!"/: :./::i <br />Tyl~'~ 1 11.35 1.30 1:80 1.90 6.35 <br />Type 2 0.45 [ 0.45 <br />Type 3 0.45 0.45 <br />Type 4 <br />Subtot.a.l I 1.35 [ 1.30 ,1 2.70 [ 11.90 7.25 <br /> <br />PVC* 2.30 3.50 3.40 9.20 <br />(Stormwater) <br />PVC* 0.81 1..35 1.30 1.90 5.36 <br />(Buffers) <br />PVC* 0.77 3.73' 4.56 <br /> <br />238 <br /> <br /> <br />
