Spirit Hills Subdivision Application — Asleson read the background from the tracking sheet, which discussed a formal application submitted to develop Spirit Hills under a Planned Overlay Development process. Mr. Goertz was at the meeting to discuss the application. There was a conservation easement in the West, and the open space was set back 150 feet. Mr. Goertz indicated that shifting the cul -de -sacs moved the two closest lots to the open space to 160 feet away. Chair Lanyon inquired of the meaning of the dotted line running from north to south across the map. Mr. Goertz answered that it was a remaining topographic line. Donlin questioned the meaning of Type B Soils. Asleson responded it was a wet hydrotype soil. Trehus asked about how many acres of wetland were present in the area. Mr. Goertz answered there were 9.4 acres, and the higher site was just less than 10 acres. Asleson explained that the area could be maintained for a 100 -year event. Mr. Goertz added there were only two fill areas planned, which added up to less than 7000 sq. ft. Mitigation was expanding and indicated a desire for a lift station in the northeast. Asleson noted the degraded forest had recently been developed. Donlin concurred the whole area had been degraded, and the plan was much improved. Chair Lanyon commented the southcr,i,s. ection had been moved to the southeast to keep the ditch from being fid i He added there was no known burial site on the property. Donlin indic ated the plan had vision, but urged Mr. Goertz not to build on the floodplain. Mr. Goertz assured the Board that there were no plans to build on the floodplain, and explained the fill areas were pits that may have been for garbage. Donlin inquired about the meaning of the 3A inch hundred -year event. Mr. Goertz responded that the watershed engineers defined it, but it dealt with controlling the runoff. Donlin presented that the Environmental Board had been considering increasing the water level in the wetlands around Cedar Lake by building a dam where Highway 49 crosses the creek, and inquired about its potential impact on the development. Asleson noted that a dam was located on Baldwin Lake.
