Plan Council Minutes 2003 05-29-03 Page I of 4 4 UNITED CITY OF YORKVILLE APPROVED WITH REVISIONS Plan Council Meeting Minutes JULY 319 2003 Thursday, May 29, 2003 Attendees: City Administrator Tony Graff Richard Hart—CPD - Police Sergeant City Engineer Joe Wywrot Eric Dhuse - Public Works Director Planning Coordinator Anna Kurtzman Executive Director of Parks& Recreation Laura Brown Mike Schoppe- City Planner Jeff Freeman - EEI Lynn Dubajic—YEDC Tim Fairfield—Paramedic - YBFD Guests: See attached The meeting was convened by Tony Graff at 9:40 AM. Minutes The May 8, 2003 minutes were accepted as presented. PC 2003-04 Caledonia—Preliminary Plan A memo May 28, 2003 memo from Mike Schoppe to Administrator Graff was reviewed. Items of special note were: • It was recommended that the developer provide architectural plans, elevations and a streetscape in an effort to demonstrate how the narrower than normal lots and side setbacks will appear. The developer provided an example of a streetscape showing architectural styles and elevations at the meeting. Mr. Schoppe recommended that the exhibit show the dimension of the houses and it be to scale. He also suggested it represent a more typical situation or a straight street rather than a curve. • Outlots A, B, D, and E be labeled"To be owned by Homeowners Association" and Outlots C and F "To be conveyed to the City of Yorkville" on the preliminary plat. The usefulness of Outlot F was discussed. • Existing vegetation around lots 99 and 100 should be identified and described on the plat. • Jurisdictional, isolated or farmed wetlands should de delineated on the plan. Mr. Schoppe asked if a wetland delineation had been done and the developer said yes but they were unable to locate it. . o Clarification of what is dedicated to the City in Outlot F should be noted on the plan along with the size and condition of the site. Also discussed was the additional property south of Outlot F. Matt Fiascone from Inland stated that the property south of Outlot F was going to be conveyed to the city at a later date and is not included in this plat. Reconfiguring Outlot F in an effort to make it more useful as a soccer or baseball field was discussed. Mr. Schoppe asked if it would be possible to add 125' to the south property line of Outlot F because the minimum dimension for athletic fields is 400' however the width of Outlot F is approximately 300'. It was discussed that the land was not suitable for roads or buildings but could be leveled off and used for recreational activities. Mr. Fiascone noted that per the Plan Council's recommendation at the last meeting, four lots were removed to already reconfigure Outlot F its present design. By adding 125' south of the outlot, it was decided that the four lots could be added back to the plat. Also discussed was the relocation of utilities in the park area. Page 2 of 4 Mr. Graff stated that the City Council will look for a recommendation from Mr. Schoppe that this development is acceptable. Mr. Schoppe stated that a 9000 square-foot lot development can be successful but in order to insure this, building standards should be put in place as part of the approval. The standards should be applied to setbacks and architectural standards. Mr. Graff asked Mr. Fiascone if a development agreement could be negotiated so that these standards would be in writing since they are not in the PUD agreement. Mr. Fiascone agreed. Other items discussed were: • Side-yard utilities and storm sewer locations—the layout of the storm sewers creates twice the amount of storm sewers that the City has to maintain. • The location of the Yorkville-Bristol Sanitary District's (YBSD) sanitary sewer line, the City's 16" water main and the easement for the sanitary sewer line. Mr. Wywrot suggested running the water main between lots 51 and 52. Dividing the sanitary sewer easement (15 feet on each side) between this property and the neighboring property was discussed and Mr. Graff stated he would contact the neighboring property owner to discuss the easement. • A May 20, 2003 letter from City Attorney Dan Kramer regarding the status of the project and the history behind it was reviewed. The Plan Commission would also be receiving copies of the letter. Mr. Graff stated that the City wants to see the project finished while preserving the quality of the engineering. Jeff Freeman from EEI reported that EEI was doing a full hydrologic and hydraulic analysis of the Rob Roy Creek. He clarified that there are two models that work in concert to develop the flood plain elevations; the hydrology model establishes the flow and the hydraulic established the elevations. The study was originally submitted to the IDNR in August 2002 for flow certification which was received the beginning of May 2003. The next steps are to map the flood plain and the flood way, submit to FEMA and go through a public hearing process. This could take several years. However the report is currently the best available data and other subdivisions are using it to manage the flood plain in the area. Mr. Freeman distributed an aerial view of the proposed subdivision and a draft of preliminary water surface profiles. Mr. Freeman explained that John Whitehouse from his firm did the engineering report for this subdivision but was unable to attend the meeting. He presented Mr. Whitehouse's report: • Mr. Freeman distributed and explained an aerial handout which showed cross-sections from the hydraulic model. He noted that the box culvert at the Burlington Northern Railroad tracks is somewhat restricted and it backs up water upstream of the tracks with an elevation of 641.46. This stays at about 641.5 until cross section 332 until it builds to the gradient of the creek (see attached). A brief comparison to the existing topography in the preliminary plan shows that a significant amount of topography is below the 641.5. This affects several lots being proposed. There is a chance that there are higher elevations between the creek and where the subdivision begins which could restrict the ability for the flood water to move into the subdivision. A more detailed topography study could confirm or deny this. The aerial picture shows significant wet areas moving up from the wetland area farther to the northeast near the park site which follows the topography on the preliminary plan. Mr. Graff clarified that the lots affected by the study need to be at a certain height level to be outside of the flood plain. Mr. Freeman stated that they need to be above the base flood elevation which is 641.5 in the southern section and builds farther to the north. Mr. Freeman questioned the status of the following studies and issues: • Drain tile—the developer stated that he was not sure if the drain tile study had been done yet. Page 3 of 4 • Traffic -the developer stated that it had been ordered but he was not sure where it stood. • Wetland - Mr. Freeman noted that the wetland review had already been discussed earlier and if it cannot be found another study may be needed before the plan goes before the City Council. • IDNR Endangered Species— submitted in February 2003. Endangered species where identified three miles downstream and a letter is pending from IDNR stating no further action is needed. • Water main alignment—EEI recommended a 16-inch main. The plan currently indicates a 12-inch water main and the increased size would increase flow and service. • EEI recommended that the developer get something in writing from YBSD or Deuchler confirming where the Rob Roy Interceptor is going to be constructed. Mike Mondus, representing the developer, stated that the topography used on their plan was probably based on different datum than that used for the creek study. Mr. Graff noted that this issue needed to be resolved before going to the Plan Commission. He suggested that Mr. Freeman and Mr. Mondus review and compare their datum as soon as possible and issue a written response. They felt they could do this before the Plan Commission meeting. Mr. Schoppe asked how EEI would respond if the Plan Commission asked if any of the property was in the one-hundred-year flood plain. Mr. Freeman stated that they would respond yes. He explained that even though FEMA maps do not define a flood plain along the creek or within the area, the flood plain ordinance states that where a flood plain is not defined it needs to be defined. EEI is in the process of doing this in the area. Mr. Freeman stated that EEI is comfortable sending the plan to the Plan Commission pending the Rob Roy Creek flood plain study and the Rob Roy Interceptor project. Mr. Graff noted that if a comfort range is met with the flood plain data, the plan can move on. If the flood elevations dramatically affect the subdivision, the plan will be pulled off the Plan Commission agenda. Anna Kurtzman noted that the City has a street naming policy and that there needs to be at least one historic name in the subdivision. She also noted that there are streets that continue through the subdivision with different names on them. This causes confusion with addressing and public safety. This item was sent on to the June 11, 2003 Plan Commission meeting pending engineering on the flood plain. Windett Ridge Final Plat—Update & Process Jeff Freeman reported that Windett Ridge had submitted for their grading-only permit and the engineers have been working through the review. EEI is willing to recommend approval of the grading-only permit subject to the storm water review which is not finalized yet. Other issues discussed were: • The large wetland area in the middle of the property. • Letter of Credit—Mr. Wywrot will get the standard bond form to Larry Vaupel. • Detailed engineering review comments due in the next few weeks. • Sewer capacity issues and IEPA permits. • The final plat and the effects of the lack of sewer and water service to the area. It was recommended that the plat be approved subject to engineering review and approval. After much discussion, Tim Fairfield from the YBFD noted that the plat only reflected one entrance to the Page 4 of 4 subdivision. Upon closer examination, it was discovered that the plat was incomplete and did not reflect the other entrance or the commercial area. Due to the error, it was discussed that the mass grading could begin while the IEPA permit process proceeded. Ms. Kurtzman recommended that the setbacks be indicated on the corrected plat. The final plat would be corrected and brought back to the June 12, 2003 Plan Council meeting. If everything is in order at that time, the plat could proceed to the July 2003 Plan Commission meeting. The Highlands Final Plat—Update & Process This item was tabled since the final plat was never received from the developer. Additional Business None. Meeting adjourned at 11:15 P.M. Respectfully submitted, Jackie Milschewski, City Clerk
