Mr. Corkle replied that that would not be the case if they assumed that everyone left their homes at the same time. The numbers referenced in the study were done for the peak hours of 6:30 a.m. to 7:30 a.m. Commissioner Sweet stated that she is concerned with the overall impact of the area. Mr. Corkl'e replied that they estimated that there would be 2,000 trips from the development in a 24 hour period. 20 percent of those trips would go down Dysprosium Street. Commissioner Johnson stated that there are serious issues along Dysprosium Street and the City does have some responsibility on resolving those concerns. Mr. Black stated that the peninsula is an area where there will be City sewer and water, which is quite different than the areas that are developed with ~ acre to 1 'A acre. They have already reduced the number of lots on the peninsula and the smallest lot would be 18,000 square feet and largest lot would be 1 ½ acres. During the neighborhood meeting he had requested an opportunity to determine what type of home could be built on the "dog house" lot and if it was not feasible to build on, then they would split the lot. He explained that the peninsula homes will be the most expensive homes in the development ranging from $250,000 to $400,000 and they will keep those lots custom lots. Mr. Black presented a picture of two story 2,300 square foot two level home built at a minimum of $250,000 that would fit on the "dog house" lot. If that home were built on .that lot they would be abiding by the 35 foot front yard setback and 50 foot rear yard setback. ~ City Engineer Jankowski explained that the DNR has jurisdiction up to the ordinary high water mark and very typically there is a buffer wetland that goes beyond that point a couple feet higher which is under the restrictions of the WMO. When the' delineation of the site is completed they will pick up where the boundary of the wetland is and then verify that with the WMO, then an easement will be placed over the wetland. He also explained that the volume of retention ponds being proposed is a function that will be looked at by the WMO engineer. In regards to the comments made regarding the water levels of the existing wetlands, the entire project is within the same water subdistrict and all of the run-off will stay within the district. He does not anticipate that there be will be an impact on the ground water levels. Commissioner Johnson inquired in regards to the large drainage pond being proposed. City Engineer Jankowski replied that the ponds will need to be constructed to NERP standards, which at the water level .there will be a 10 to 1 bench to prevent a steep slope. Dave Putnam, Engineer, Midwest Land Surveyors, stated that the pond that is identified and located in the proposed location because it is where it will function for the site. The location suggested by residents for the pond would place the retention pond in a natural low area which is a designated wetland and they are not allowed to pond in that area.
