RCWD who will review their Chain of Lakes system modeling. They will review elevations and impacts that changing a lake level has on both upstream and downstream watersheds. The agencies will include the impact to the flood elevation of Reshanau Lake. A lake level change could result in additional properties being within a new Federal Emergency Management Agency flood zone. The permitting for this type of request typically takes multiple years. At the last neighborhood meeting residents were interested in testing their wells. The City provided well testing kits to each property owner in both neighborhoods. We are hoping to receive feedback on the results at the upcoming neighborhood meeting West Shadow Lake Area Area residents have previously expressed interest in the extension of municipal sewer and water as part of the project. The existing septic systems are aging and the lot sizes may limit the ability to replace systems cost effectively. Currently there are systems that are located in the public right of way which will need to be considered with the roadway reconstruction project. Extending sanitary sewer would improve the water quality within the watershed and specifically Reshanau Lake which is an impaired water. The septic system age is as follows, note the majority of these systems do not meet current standards and are considered non- compliant: Number of Systems: 62 0-5 Years Old: 5% 5-10 Years Old: 8% 10-15 Years Old: 8% 15-20 Years Old: 6% 20+ Years Old: 73% The Minnesota Department of Health had 49 wells on record. The well age is as follows: Number of Wells 49 10-15 Years Old 2% 15-20 Years Old 2% 20-25 Years Old 10% 25-30 Years Old 10% 30+ Years Old 76% The extension of both municipal utilities would provide property owners the opportunity to subdivide their parcels. There are approximately 9 subdividable parcels with a majority of them located on the west side of West Shadow Lake Drive. If municipal utilities are extended in the West Shadow Lake area, the project costs would be covered by either special assessments or connection charges. The extension of municipal utilities will ultimately be up to the property owners. The procedure for assessing beneficial properties is governed by Minnesota State Chapter 429 and the City’s Charter. The first step is being considered tonight. A Report on Improvements (Amending May 8, 2017 Feasibility Report) including the project cost, preliminary design and a proposed assessment roll will be presented to Council on December 11, 2017. The Public Hearing would then be held in January of 2018.
