CONSIDER APPROVAL OF SEPTEMBER 16,1998 MEETING MINUTES MOTION BY HAGGERTY, SECONDED BY TRAPP TO APPROVE THE MEETING MINUTES OF OCTOBER 21, 1998. MOTION PASSED UNANIMOUSL Y. III. LAKE ACCESS CLOSURE City Manager Frank Boyles spoke to the group about what Council was looking for' in regards to the lake access closure and clarified the directive. The issue for the LAC to decide on is what criteria should be used, regardless of their opinion on the issue, in making the decision to close City accesses to the lake. Also, what communication process should followed. Council would like a response as soon as possible from the LAC in report form. IV. COMPREHENSIVE LAKE MANAGEMENtT .PLAN (CLMP) A. PRESENTATION BY STEVE WOODS: Woods reviewed some of the goals the Watershed District has in its' second generation plan. He stated that the Watershed plans to move ahead in the next 5 to 10 year period utilizing the existing 36" outlet pipe and stabilizing the outlet channel down through Shakopee. Several databases have been developed. One shows that there are 88 low homes around Prior Lake below the FEMA flood elevation. A graph was shown that depicted lake level impact vs. home valuation. Also, a computer model has been developed that is ready to run different rainfall scenarios. The Watershed is going to be doing a feasibility 16200 Eagle Creek Ave. S.E., Prior Lake, Minnesota 55372-1714 / Ph. (612) 447-4230 / Fax (612) 447-4245 AN EQUAL OPPORTUNITY EMPLOYER study in 1999 to look at what scenarios to look at to put into the computer model. "'" To add an additional 36" outlet to the lake would cost approximately $500,000.00 which would increase the outlet capacity to 100 cubic feet per second. The district's first intent is to get the administrative paper work done so that the outlet can operate under any conditions, without the possibility of downstream conditions causing the outlet to be closed. Braddy: Is the Watershed's plan being coordinated with the City? There is a planned City project in the Candy Cove area that will have a lot of runoff going into the lake. Woods: We are working with the City in looking at different alternatives, such as narrower street widths, but we haven't mandated the City to do certain things yet. Larson: Who's going to pay for the upgrade and stabilization of the outlet channel? Woods: The final agreement hasn't been worked out yet. The lower part of the channel will be paid for by Shakopee. The costs will be pro-rated upon contributing flow rates. Breitbach: If there is additional land acquisition for widening of the outlet channel,who would hold rights to that land? Woods: Probably both of the cities, Prior Lake and Shakopee. Larson: What would you expect to see if nothing further was done to the outlet, except stabilizing the channel? Woods: You expect to see an increase in the amount of time that the lake level is up and the high point that the fake reaches would tend to increase over time. Kedrowski: What if the money that is to be put into increasing the outlet capacity and channel stabilization was put into buying our low homes in the flood plain around the lake? Woods: That's why we did the low home data base and one thing that we want the computer model to answer. If we went up to 150cfs discharge rate, triple what we have now, we would still have 16 homes in the floodplain. At this point we would be spending about one million dollars on the outlet, on the low side, and then there's the additional costs of upgrading the channel down to the river. Leichty: Would you explain to the audience the District's plan for restructuring the outlet so that a true 50 cfs could be discharged. Woods: We hope to put a different outlet in, around 2002, a longer weir structure. Currently the lake has to be up a number of feet to outlet 50 cfs. This would allow us to outlet 50 cfs at lower elevation, instead of waiting until the lake reaches an unacceptable level. There was a lot of discussion about assessments, condemnation, township development in the southern part of the District, impact of lake levels on home values and other issues. The District would like some feedback from the LAC such as, "Is the community interested in additional outlet capacity?" B. EXAMINE PROPOSED SCHEDULE AND TIMELlNE FOR THE CLMP: Leichty passed out a draft timeline to follow which had dates for each issue for informational meetings and presentation to the Council. Members discussed the timeline and approved it with the following changes: 1) The presentation date to Council for shoreland preservation was changed from March to April, 1999; and 2) The informational meeting for surface water management was changed from March to May, 1999. MOTION BY TRAPP, SECONDED BY HAGGERTY TO APPROVE THE PROPOSED SCHEDULE AS REVISED BY THE COMMITTEE. MOTION PASSED UNA NIMO USL Y. C. REVIEW QUESTIONNAIRE RESPONSES TO THE SHORELAND PRESERVATION ISSUE: Members reviewed citizen responses to the shoreland preservation issue. After talking about what the outcome from the public informational meeting may be, it was decided that a request for proposal should be prepared to study various aspects ofthe Jake. Making decisions by opinion without having the facts will only lead to frustrated citizens. Obtaining a cost to conduct a lake study will allow the LAC whether to propose this to Council for possible consideration and funding. Leichty will work on preparing an RFP. v. 1999 LAC GOALS AND OBJECTIVES M Leichty passed out a draft proposal of the 1999 Goals and Objectives. Members were asked to review and bring comments back to the December meeting for further discussion and approval. VI. NEW BUSINESS A. Members Breitbach and Larson were asked if they wanted to serve out their last term on the Lake Advisory Committee. Both agreed to serve another two years. B. Mankowski asked what regulations there were against raking leafs into the street and if the City had an ordinance covering this. Leichty mentioned that there was a City ordinance against this type of activity. VII. ADJOURNMENT MEETING ADJOURNED AT 8:35 P.M. ~> Respectfully submitted, ~ ~ Lanol Leichty Recording Secretary
