Excerpts from Plan Commission Minutes of July 1,2010 continued: Mr. Guy Casey asked how high the ridge line on the three (3) story building will be. Mr. Wiltzing said it will be approximately forty-six (46) feet high. Mr. Casey asked if the back of the building will be two hundred and fifty-two (252) lineal feet. Mr. Wiltzing said that was correct. Mr. Casey asked if his house sits about in the middle of the two hundred and fifty-two (252) feet. Mr. Wiltzing said he believed that was correct. Mr. Casey said his house is less than one hundred and thirty (130) feet from the back of the building which is less than the width of the back of the building. Mr. Casey asked if there is over three hundred (300) feet of green space behind the building at Eagle Ridge. Mr. Wiltzing said this was correct. Mr. Casey asked if these facilities could be designed for two (2) stories. Mr. Wiltzing said with a dramatically lower number of dwelling units or with medically unadvisable layout. Mr. Casey asked if there was only fifty (50) feet of space to the buffer yard at the back of the building. Mr. Wiltzing said it was about fifty (50) feet to the buffer yard and then thirty-five (35) feet of buffer yard. Mr. Wiltzing said the entire setback of the building from the south property line is one hundred and three (103) feet. Ms. Stickle said it is not one hundred and three (103) feet at all points. Mr. Casey said there is nothing unique about this plan that causes it to be located in this particular location. It could be built elsewhere. Mr. Wiltzing said it was designed for this site that they are presenting. Mr. Bob Dean, BWC, was sworn in by Mrs. Poland. Mr. Dean stated the entrance of the proposed development has been adjusted. He has been in contact with IDOT and they told him they will only review the plans after approval from City Council. Mr. Dean said the initial drainage plan met the requirements of the City. The allowable discharge is 6.2 cubic feet per second (CFS) He stated they have increased the capacity of the detention basin by twelve(12)percent and reduced the size of the orifice outlet to an eight(8) inch pipe which reduces the flow out of the detention basin to about 3.3 CFS. This will require a couple of hours longer for the water to run out of the basin. Mr. Dean stated before this meeting he spoke with Mrs. Scherman who owns the pasture immediately south of the proposed detention basin. The original plan was to discharge over land which would run into her pasture. Her preference is now to run the discharge underground to the open ditch. Mr. Dean said they will try to develop an easement to accommodate her. The smaller orifice will reduce the peak discharge at that location to help reduce the erosion. Chairman Anderson said if the rain is coming off the roof on all four (4) sides with no gutters and then you put gutters on all four (4) sides and it dumps into an eight (8) inch spout, you have the same amount of water coming out but you also have a lot more velocity than there was. Mr. Dean said a stilling basin will be built. The stilling basin is a structure which spreads the water out and reduces the velocity of the water before it dumps into the drainage ditch. It is made out of rip rap and it has a basin which will not stay full of water. This is a common way to slow velocity down. Mr. Casey asked if the stilling basin is in the buffer yard in the latest drawing. Mr. Dean said it is within the buffer yard on the plan. Mr. Dean said he did not know until this meeting that Mrs. Scherman wanted the pipe underground. The drawings do not reflect this. The drainage pipe will be underground which will go into the stilling basin and then discharge into the open ditch.
