Plan Council Minutes 1994 08-09-94 ^ PLANNING COUNCIL MINUTES TUESDAY, AUGUST 91 1994, 9:00 AM CITY HALL, MADISON & JEFFERSON STS. , YORKVILLE Present were Bill Dettmer , Joe Moore, Dan Laube, Bill Gchmanski and Jim Nanninga. J. T. Johnson arrived at 9: 30 AM and Bill Dettmer left at 9:45 AM. Best and Inland The applications for the special use for the bed and breakfast for Bruce and Joyce Best at 201 E. Jackson and the rezoning for Inland in Countryside Subdivision from O-Office to R-2 Duplex will be discussed at next Tuesday 's meeting. Country Hills Subdivision Bill Schmanski updated the council on the sanitary sewer plane for Country Hills Subdivision on how it will be served now and in the future. Barry Niles will be coming in with a new subdivision soon and wants to know where he could connect. The sewer shown on the map is at the entrance to Wildwood , will be by gravity and goes to the new SW. The industrial park will be hooked up. The capacity of the line out of the lift station is somewhat of a limiting factor. There is a 12" connector to the new interceptor. This lift station ( 10" line) will ultimately have as many as 5v00() PE tributary to it. Neither Country Hills or Barry Niles currently have the rights to the capacity of this lift station , as it is basically Dr. Davis ' and there is a complicated agreement to that affect. This lift station has the capacity of 80 gpm which is approximately 80 lots. There is available capacity for others at this time. The pumps could be upgraded to the capacity of the 4" force main. The pumps could be changed to allow additional capacity for the tributary area on a short term basis. Ultimately there is to be an interceptor on the Commonwealth Edison easement. Dwyers stated that they were unaware of the need for a interceptor and that everyone must start contributing to it. In Dr. Davis ' agreement , once his capacity was used up any upgrading would be at his expense. Any lots after Davis ' first 80 must contribute to any upgrading of this lift station. Someone needs to contact Metropolitan Pump to get more information on this lift station, but he feels that using 8 ' per second as a limiting factor there would be 300 gpm capacity for that lift station. Approximately 230 additional homes could still be tributary to that lift station with pump upgrading. The cost of this is undetermined. In regard to Dwyer 's plans, he is unsure who will be reviewing-his firm or the subdivider 's engineers. Dwyers are aware that an interceptor is needed. There are 2 sets of plans from 10 & 20 years ago showing an interceptor in that easement. Dwyers will have to take off site down to Wildwood entrance which is about 1v000 feet. Dan Kramer will be contacted in regards to any agreements made. Jim Nanninga asked if the lift station was enough or does force main need to be upsized? Bill Schmanski stated that it depends an how much money is spent for a temporary solution. The permanent solution is the interceptor (7,000 feet. ) J. T. Johnson had - ^ Page 2 Planning Council Minutes August 91 1994 asked Bill about Keith Kuchowski as the easement is on his land. He has a home there and would like service. The City should acquire that R.O. W. and easement as soon as possible. Jim Nanninga asked if there was a limit to his design in the industria1 park for gpm and the limiting factor is the force main as there is lots of ground water , but an 8" sewer can handle quite a bit of flow. The question is how long can money be thrown at this. This was missed at the preliminary plan with Dwyer. Dwyers and every lot beyond Wildwood is in the recapture area" The agreement with Wi1dwood in regard to the lift station states that after 80 lotsv the developers must pay the costs of additional sewer capacity. There has been correspondence that this lift station is under capacity. The groundwork has been laid , but the solutions have not been defined and the real solution is the interceptor. Jim Nanninga will contact Dan Kramer about the agreement. Any homes that are built after Wildwood 's 80 homes would have to pay any upsizing costs of the lift station. In regard to Dw*ery Bill Schmanski had met with their engineer before preliminary was approved. Bill will write a letter to Jack Kusac reiterating the discussions or check if a letter has already been written. Dwyer 's and Niles subdivsion would use all the capacity of that lift station and would be limited by the 4" main and Niles would have to contribute to any upgrading. Jim Nanninga and Bill Schmanski will meet with Dan Kramer showing him these plans and getting his input. Stepan There is lots of work needed yet on Stepan as there are lots of wetlands and it is a very sensitive area. Jim Olson is contacting the Army Corps of Engineers. Subdivision Control Ordinance Additions have been added to the ordinance on manhole vacuum testing and traffic study. Jim Nanninga wants this information to the next Public Works Committee meeting so he needs any changes as soon as possible. Joe Moore wants an additional hydrant and manholes need to be checked. Bill Schmanski brought a copy of a cross section of a street for 31 feet and it was agreed that this would be the required width. Jim would like the binder course to be 2-1/2 and Bill will check with soils engineer and put the fabric there also. J. T. Johnson reported that Prairie Park is 30 feet and feels 31 feet 1s reasonable for snowplowing. Jim Nanninga had talked to Jeff Palmquist and he agrees with the 31 feet because parking on only one side doesn 't work. On the ordinance markup there 1s 5 feet easement on side yards. A letter would be submitted to Public Works Committee with all Planning Council members signing agreeing to the changes in the Subdivision Control Ordinance. Sewer and water and drainage must be in place before building permit is issued and . . ~ Page 3 Planning Council Minutes August 9, 1994 the City may, in model areas, consider something less (all would be done on an individual basis. ) Dan L-aube stated that a soil and water opinion should be required. The verbage from Bill Schmanski in regard to the traffic study was added and the approved list of trees from Jeff Palmquist was added. On water and sewer locations, J. T. Johnson stated they must be 10 feet apart and he will check the plumbing code and look plans over again" J. T. Johnson and Joe Moore will check manhole numbers" In regard to sanitary it should be at mid-point and water at edge (3 feet off edge) and duplex being different. J. T. Johnson would like the wording on water service pipe that it may be placed in the same trench with special permission and under special conditions as per inspector. Jim Nanninga asked who was excluded from the Storm Water Ordinance. Overlot grading should take care of this. No exceptions now on storm water control . it was decided to leave it as is and have variances requested if necessary. "As builts" for street lights will be required. In smaller subdivisions a catchall phrase is needed to give the City a right to make decisions or give variations. In regard to light fixtures spacing is every 300 feet. J. T. Johnson will check out the fiwtures. Dan Laube requested that a record be kept on all underground tiles and that all field tiles must be tied into storm system. Bill Schmanski asked that on page ll on topal it should be for preliminary not preapplication conference. Jim Nanninga will get the 2 missing pages to the Council . On Overlot Grading Ordinance, the sample given out should be one with the correct grades required" J. T. Johnson stated that the builder will show his top of floor on plans and there will be a three point inspection: l ) review plans, 2> prior to pouring or after it is poured and 3) final sodding. The spot survey would be eliminated. The tolerances would be at least 2" behind setback. Bill Qettmer will be contacted in regard to surveying forms" The meeting adjourned at 10: 20 AM. Minutes by: ud
