Mr. Kelly explained to you that the owners of the site are interested in enhancing the large lowland portion of the site. We realize that permits will be needed for any modification to wetlands and/or navigable waterways at this site. Therefore, we need your assistance in making a determination of navigability of several agricultural ditches that run through the site. Once this determination is completed, we can identify the type and level of permits and approvals necessary for the project. All of the appropriate reports and applications will be submitted once the navigability determination is made and site topographic maps are generated. I have attached several maps of the site for your review and information. Copies of these maps will ultimately be included with the wetland delineation report for the site. Once this report is completed, a copy will be submitted for your review. The following is general description of the site and the conceptual plans for its enhancement. The site lies south of the Village of Cottage Grove within the Town of Cottage Grove in the SE 1/4 of Section 16 and the SW 1/4 of Section 15, Township 7 North, Range 11 East. The site lies outside of the current urban sewer service boundary. The property was formerly owned by Lehndorf Farms LTD, but was purchased by Dwight and Dale Huston within the last year. Based on preliminary delineation results, there is one wetland area at the site. The wetland is about 84 acres in size. Historically, the wetland was part of a larger wetland complex that drained to Koshkonong Creek. The area was drained for agriculture about 50 years ago using V.5-- lateral ditches and drain tile. Although the NRCS wetland map shows extensive Prior\' t' Converted Cropland at the site, most of these areas have not been farmed since 74 and have reverted to wetland. The wetland is dominated by giant ragweed (Ambrosia trifida), reed canary grass (Phalaris arundinacea), stinging nettle (Urtica dioica), and box elder (Acer negundo) on Houghton muck soils. In general, the wetland ranks as low quality using WDNR's A Member of The Smith Group, Inc. Ann Arbor/Chicago/Detroit/Madison/Phoenix/Washington D. C.
