Because in~tituLion or a ~peed limit would nece~.~itat.e a cbange in tbe Joint Puwen> Agreement witb Shoreview, I think we should hold on to our legal right to the 300' buffer in the current ordinance until we can get tbe agreementofSboreview and approval hy tbe 11NR oftbe speed limit T would not agree to changing to 150' before another protection such as a speed limit was in place. By cutting out and weighing portions of the DNR and Roseville maps of Lake Owasso, I was able to determine the proportion of the lake which would be affected by a reduced speed limit I have identified three potential boundaries for the limit, A (least restrictive), B, and C (most restrictive). Although I identified A,B. and C roughly based on lake dimensions. they correspond approximately to: 3/7/96 to: City of Roseville. Dennis Welsch, city council members from: Peggy Egli, 705 Heinel Circle regarding: Lake Owasso dimensions relative to possible speed limit in SWend I believe that a reduced speed limit in the SWend of Lake Owasso, in conjunction with a 150' buffer zone as proposed by Shoreview: would be a satisfactory solution to: _ maintain watcrquality and reduce boat-gencratcd turbidity in thc lake. _ address residents' concerns about increased speedboat noise. _ maintain aesthetic and wildlife habitat value of the SWend of the lake. _ prevent the inslallaLion of a new slalom cuurse at the lake's narrowest point.
