The number and total area of lots has been reduced and the wetland fill amount and location has changed slightly. As you may recall,the original proposal entailed a subdivision of approximately 76 acres in 19 lots,and required 0.333 acres of wetland fill out of a total of 8.84 acres of wetlands. A permit for the fill was issued by the U.S.Army Corps of Engineers(COE)on November 3, 1997,(permit No. 98-00562-NW- JBK)and was certified by the Wisconsin Department of Natural Resources on December 3, 1997. Subsequent hearings and approvals for this earlier configuration were obtained from the Dane County Regional Planning Commission on January 29, 1998,and the Dane County Board of Supervisors, Zoning, and Natural Resources Committee(ZNR)on March 3, 1998. The environmental corridor map was also amended to reflect our wetland delineation,the proposed 0.333 acres of wetland fill,and a proposed removal of 0.52 acres of old fill from former wetlands, as illustrated on the enclosed preliminary plat of Deer Haven Development. Finally,a zoning variance was granted by the ZNR on Outlot 1,which was planned as a conservancy area and,therefore,did not require access developments. Since these approvals,the Dane County Regional Airport(DCRA)has purchased lots 9, 10, 11, 12,and 13 and about half of Outlot 2 in order to expand their buffer area and clear zones for aircraft operations. The airport intends to leave this area in natural land uses. The total area purchased was approximately 35 acres, or about half the original development,which required redesign of the east side of the subdivision. A 1-acre easement was later retained from DCRA for a storm water basin. An illustration of the current proposal is included for your reference. As a result of this redesign,the wetland impact has been reduced to 0.078 acres from 0.333 acres and should still be covered under our original permit. The impact will now be from a storm water drainage ditch versus a two-lane asphalt access road in the original proposal. As the original proposed 0.52 acres of wetland fill removal now lies within the DCRA property, we now intend to design the 0.60-acre storm water basin as a permanently-flooded wetland with an emergent fringe. By copy of this letter,we will notify Jim Knowles of the COE of these changes so he can update our permit file.
