• Mr. Mark Sponem <br /> June 23, 1998 <br /> Page 2 of 3 <br /> ✓ Preservation of exisiting trees and s•• bs within the shoreland of the unnamed streams. <br /> ✓ Development and implementation o i a long-term stormwater management plan that includes <br /> restoration of historic wetlands, cre: ion of wetland stormwater detention basins, and creation <br /> of vegetated stormwater conveyance swales. <br /> ✓ A staff experienced in and licensed i•r pesticide application will maintain the course. <br /> Although,much of the public contin es to believe that golf courses have an overall <br /> detrimental impact on the water qu. .'ty, current pesticide/fertilizer use patterns and integrated <br /> pest management philosophy should change these attitudes over time. Our review of <br /> fertilizer use for the Town of Cottag Grove indicated that the course would not require <br /> significantly more fertilizer than wo d be applied to a cornfield. In addition, fungicide use at <br /> this site will be minimal given that v-ry little of the golf course area is shaded. It is also my <br /> understanding that WDNR consider,• pesticide/fertilizer use/impacts when reviewing our <br /> stormwater management plan. <br /> Wetlands <br /> As we've discussed,the Wisconsin Well: d Inventory(WWI)mapping is to be used only as a <br /> guide and does not replace the need for . • on-site wetland delineation. My delineation was <br /> completed using the current federal gui. : ce(1987 Wetland Delineation Manual)and was <br /> reviewed and accepted by both the WD • and U.S. Army Corps of Engineers(USACE). The <br /> results of the wetland delineation conci •ed that several acres of the site were erroneously <br /> mapped as wetlands by WWI and that . • additional wetland area,that was previously unmapped, <br /> exists at the site. <br /> The project, as currently designed,will '• 'act 0.1 acres of jurisdictional wetland. There is no <br /> practicable alternative to this impact. DNR and USACE have indicated that will issue the <br /> necessary permits and approvals for this etland impact. <br /> Soils <br /> Most of the soils beneath the area to be sed for the golf course are Sable silty clay loam. <br /> Although in an undrained condition,the - soils may impose severe restrictions on golf fairways, <br /> these soils are adequately drained at the •ite by the unnamed streams and possibly with drain tile. <br /> This drainage when coupled with develo.meets in turfgrass science,make these soils well suited <br /> for golf course use. The undrained Sable soils at the site are wetland areas that cannot be used <br /> without state and federal permits or are s ply areas that not incorporated in the golf course <br /> layout. <br /> Sable soils have the added benefit of b•' g clayey soils. The clayey nature provides protection to <br /> groundwater since they are relatively im -rmeable and many pesticides readily bind to clay <br /> particles. <br /> There are soils at the site that are classifi-d as Class 1 prime farmland(Kegonsa, Plano, and <br /> Dresden). The Dresden soils that exist o• the site are found primarily on the glacial drumlin just <br /> north of the residence. This area is curr- tly in permanent grass cover and has not been farmed <br /> for several years. This area is not being •sed in the golf course layout. The Plano soils are found <br /> on the western edge of the property. Mo.t of these soils are also in permanent grass cover and <br /> have not recently been fanned. Using th Soil Survey as a guide, only a small portion of the <br /> p <br />
