, , ti 1 Spring Hili Golf Club Sequencing Application Addendum June 20, 2012 Page 3 of 3 or not. Spring Hill was told that the bank has deposited 15 percent of their credits into the state bank thus far. Other banks within the same Major Watershed (20) as the impact site and/or within Hennepin County were also considered. A total of 14 banks met one, the other or both of these criteria. Of those 14, two do not have enough credit, three are not for sale to the public or the ovmer could not be reached, two are not Corps-approved (it is not known whether the Corps has jurisdiction on the Spring Hill project as of this date), one is selling for$2.50 per square foot (considered to be outrageously priced), one has just upland credits (assumed to be a problem for the Corps). This lea�res four banks that are possibili�es f�or the Spring Hill Golf Club (Banks#1310, 1346, 1410, and 1414). The only one of these banks in the same Major Watersh� as the project site is#1346 but it only has Type 5 wetland credits available. Although credits deposited in the state wetland bank have been converted to "Standard Wetland Credits" (SWC), the preference would be to replace the Type 2/3 wetland impacts with Type 2 wetlands if possible. This narnows the banks to #1310 and 1410 (Heritage Woods). MnRAM Analyses Please see the attached MnRAM summaries which indicate that the overall wetland basin as well as the north and south impact areas generally score "Moderate"for almost every category. The MnRAM for the on-site mitigation area generally scores moderate to high, primarily because it would have a managed upland buffer with an average width of 25 feet, would be protected by a permanent conservation easement and would be managed to score "High" as a Type 2 fresh meadow for vegetative diversity/integrity. When completing the MnRAM for this basin, obviously some projection is involved since it is not yet constructed. Assumptions that were made include: 1)the wetland would be constructed/maintained as a Type 2 wetland, 2) active management would be done per a Vegetation Management Plan to maintain the wetland as a "High Qualit�'fresh meadow, 3) BWSR Mix 34-271 or similar would be used for the wetland, 4) BWSR Mix 35-641 or similar would be used for the upland buffer, 5)the condition of the mitigation wetland was assumed to be assessed one growing season after the first full growing season, 6) Lester topsoils in the area of the mitigation site wouid be stockpiled and used as topdressing — hydric soils from wetland impact areas would not be used because of reed canary grass and cattail problems. Piease consider the aforementioned and attached ir�formation as an addendum to our March 30, 2012 Sequencing Application. cc: Tim Johnson, Spring Hill Golf Club Kurt Quaintance, James R. Hill, Inc.
