WCA Replacement Plan Application Trout Bmok E~ates June 28,2004 Page 5 The NWC areas are in an areas mapped as Beltrami fine sandy loam and Talmoon loam according to the Sherburne County Soil Survey (see Figure 5 in Wetland Delineation Report-Appendix A). Initial investigations indicated that the soils at the proposed NWC area have soils with characteristics indicative of a soil in between a Beltrami and the adjacent Seelyeville wetland soils. The Talmoon loam is listed as a poorly drained soil. The NWC area would be excavated to a maximum finished bottom elevation of 907' with an undulating bottom not exceeding 907.5' in Wetland 1, and elevation 912.0 in the NWC next to Wetland 3. The hydrology source of the mitigation wetland will be surface and ground water as it is in the existing Wetland 1. The plan proposed should produce a saturated palustrine emergent (Type 2 inland fresh meadow) wetlands. The created wetland area will be seeded with the wet meadow mix and at the rates described on the Grading Plan (Figure 3). Additional Public Value Credits (PVC) are also being generated through establishment of an upland buffer along the northern boundary of Wetland 1 and at the NWC area at the southeast corner of Wetland 3. These upland buffers are shown on Figure 3 and will measure 37,545 sq.ft., 37,225 sq. ft. and 9,230 square feet respectively. These areas (1.93 acre total) will be used as a portion of the second half of the 2:1 replacement requirement. According to Minnesota Rules 8420.0541 Subp. 6, upland buffers are eligible for an amount of credit not to exceed 100 percent of the replacement wetland credit area. The total replacement wetland credit area for this project will be 168,000 square feet (84,000 square feet of NWC and 84,000 square feet of upland buffer). The buffer area will be planted with the native prairie seeding specifications outlined in Appendix B after final site grading is completed.
