Plan Council Minutes 1994 08-23-94 ' PLANNING COUNCIL MINUTES TUESDAY, AUGUST 23, 1994, 9:00 AM CITY HALL, MADISON & JEFFERSON STS. , YORKVILLE Present were Jim Nanninga, Jeff Palmquistv Tony Graff , Bill Schmanski and Becky Johnson. Also present were Ron Bauer , Jack Cusack and John Schumacher. Jeff Palmquist passed our proposed criteria for parks and open space for developing and accepting land , looking at parks classification systems and standards, and how to adopt a park system. This is based on the Fox Valley Park District standards and is on the stringent side. It is designed to be easy on the maintenance and based on the assumption that parks are an open space, not leftover space. A provision should be made that parks not be next to a major highway. Parks should be on flat , high & dry land , open to the community, accessible to the neighbors and free from detention or retention (but can be part of it) . There will always be a homeowners association with every detention area or the lots that go through , one person will be responsible (always will have the inconsistent maintenance) . Tony Graff stated there are problems with the green areas in Countryside Center because the homeowners association has dissolved after 20 years. Becky Johnson stated that many homeowners mow the area. There are problems with ATV 's, dogs and dumping of yard waste. Tony Graff is working on an ordinance to take care of this problem" Jeff Palmquist explained the proposed criteria. The existing land cash ordinance should be reviewed and a criteria for land donations should be formulated. Specific criteria is that land must be free from detention or retention and be above the 100 year flood leYelv land should be contiguous and in a configuration to allow for the development of the proposed recreational components" It was agreed that neighborhood and community parks shall have a minimum of 25% of the total perimeter directly fronting a public roadway, the minimum secondary access should have a 20 feet easement , if walking distance is greater than 1 ,000 feet , an 8 feet paved walk and some type of pedestrian barrier fence to be approved by the City" Bill Schmanski questioned slide slopes above the water" He suggested a 5. 1 slope to 3 ft. below to 3 ft. above, but has concern about the emergent materials. Jeff Palmquist will research this. Also added will be some type of mulching that is acceptable to the City. Discussed was core credit for the 30 ft. buildable area that shall be provided around the lake above the 100 year flood level " Tony Graff stated that Countryside Center wants the City to take over their ponds and the City needs some standards to go by, if this is done. It was agreed that lakes be accepted , if free from defects after two years, by the City Council after recommendation from the Park Board. A provision will be added that parklands be tied into a City wide pedestrian system and items such as 5' sidewalk , bag mix , top soil , etc. be followed as per the Subdivision Control Ordinance. , , Page 2 Planning Council Minutes August 23, 1994 Location of neighborhood parks shall be avoided adjacent to major highways and major collector roads. Park sites which will be used as borrow pits shall be stable enough to support the proposed park improvements as approved by the City Engineer. The proposed criteria is for a 5 level park classification system. It was questioned whether small parks would be accepted or would it be on an individual basis. Also needed to be added was location of neighborhood parks that don 't service the people of the area. Jeff stated that the City should be looking more at larger parks (not at every subdivision that comes in) but within the service area. Service areas are very important but have had no guidelines for parks before. Wetlakes should have silting basins, minimum of 6 ft. depth and 12 Q. or 25% of the area and the blue-green area should drain within 48 hours. Street lighting should be added to the list of improvements for parks. Jeff Palmquist will get proposed guidelines to Rec Board by Sept. 14, Planning Commission on the 21st and then to Committee of the Whole and City Council . No one was present for review. Jeff Palmquist stated that care is needed before going too fast on this property" He feels that plan is not executed as carefully as it could be, and would need to take our time to uphold the integrity of the site. A site analysis needs to be done and density and sanitary must be addressed. John Schumacher of Morris Engineering presented final engineering plans. He explained positioning of the water lines. Ductile pipe will be used and placed 5 ^ below existing ground. The sanitary sewer will be connected to existing manhole. Some lots will have horseshoe drainage in back yards and some special treatment of driveways and garage floors will be needed. Special treatment will be used to make the 2% grade work. The sanitary sewer is designed at a minimum of 1%. Bill Schmanski stated this is not currently in the service area of the Southwest Interceptor but there is potential to access other property. The drainage area was explained. The size of storm sewer in based on a 5 year storm with 3 detention basins. There will be temporary storage area for heavy rains and plans are for a 30 feet wide drainage area. There is a 20 foot conservation easement , trees will not be destroyed and a tree survey will not be done. The existing trees will be looked at after grading plan is received and soils information is needed before street section is finalized" The off site roads need to be addressed. Design of roadways still must be done" All sewers will be in R.O. W. and no surface discharge to the north. The location of the water main was ' Page 3 Planning Council Minutes August 23, 1994 discussed. John Schumacher asked for suggestions for naming one of the roads. Bill Schmanski agreed that digging a pond would be acceptable from a storm water management standpoint , but there would then be a body of water newt to the park. More storage would be provided than the ordinance requires and the pond may have to be lined. Also discussed was discharge of water as other properties may be coming up for development. Jim Nanninga stated no final acceptance will be done until City Council sees Christy 's replat. Jeff Palmquist asked about the 60 ft. easement between lots 72 & 73. Bill Schumacher stated that in the future the area may be a street , dedicating it now as a R. O. W. It was suggested to go to Clemens ' to sign an agreement to maintain the R.O. W. and also access is needed for emergency reasons. The Planning Commission had agreed than a property owner not be locked out of use of their property. Some type of recorded agreement will be required. Lot sizes were discussed. Bill Schmanski stated that they will be inspecting full time (primarily underground) v not on testing or layout. Jack Cusack reported that off-site permit has been received from I . D. O. T. There is a problem with water main , but feels it can be resolved. Bill Schmanski suggested that they consider looking at parallel sewers and this could be revised during the process. Submit this to E. P. A. now and make changes later. The sewer and water will be taken to an intersection until commercial develops and should be part of original plan. The temporary deadends will be tied into commercial . Jack Cusack reported that I " Q. E. S. has been approved. I . D"O. T" has requested some striping but will need some correspondence from the City as he doesn 't feel it should extend to Clover Court. A 4 way stop will be at Clover Court and Country Hills Drive and there will be a sharper taper and more storage. A left turn bay may be added from Rt. 71 in Phase II . The soils have to be evaluated. It was recommended that they use 2" stone and would like fabric used~ Tony Gra+f stated in regard to 911 there was a concern with street names changing. The numbering of the buildings was discussed. The problem of upgrading the lift station must be addressed" The original agreement with Davis ' must be looked at. The existing pumps can handle 80 lots dedicated basically to Wildwood and the 4" force main could handle Wildwood and Dwyer 's Subdivision. The concern isv can larger pumps be used to accommodate additional flows. Two steps to handle this (instead of spending money on the interceptor) is to upgrade the lift station on an as needed basis, there must be contributions after the original 80 lots and after that money is needed for the interceptor. Bill Schmanski is recommending that money be collected at time of building connection. The lift station must be upgraded. Bill Schmanski will contact Metropolitan Pump to see what was installed. Some - ' ^ Page 4 Planning Council Minutes August 23, 1994 type of recapture would be needed for upgrades to lift station and City would collect from whoever was tributary. It was suggested that a special service district be formed for collecting money for the interceptor. The Commonwealth Edison easement must be acquired. Bill Gchmanski will put together information for the interceptor. Minutes by: lios ^
