MINUTES OF THE ORONO CITY COUNCIL MEETING Monday, November 9, 2015 7:00 o'clock p.m. 4. MET COUNCIL SEWER MAIN PROJECT — JEFF SCHWARZ, P.E. (continued) Schwarz stated they will be using precast structures and that the contractor will be able to excavate the site, drop the structure right in, connect them up, and then backfill the area. Schwarz displayed a picture of the type of work that will be performed. The Three Rivers Park Trail will be used for access on the north side so there will be no interruption of traffic during that phase. Phase 11 of the project goes from Hillside Drive over to the gravity section. Currently this work is scheduled for the summer of 2016. Schwarz noted the MCES has been receiving some comments regarding the schedule since Shoreline Drive will be closed for a period of time, which will impact Wayzata more than Orono. Some of the features of this segment will require deep excavation. As a result, the road must be closed for that work and that they are attempting to complete the work so that the Blake School will be impacted the least amount possible. Schwarz indicated they are reconsidering some of that work based on public comments received last week. Schwarz stated one of the issues they have encountered is that County Road 101 will not be completed until the fall and that they are taking another look at the project. Schwarz noted the reason for having to close the road is because the work involves 25 -foot deep excavations that will take quite a bit of earth moving. Schwarz stated it is a narrow road, which would make it difficult to try and keep one lane open or put a temporary road in. Schwarz stated they should have a conclusion on other options for the Wayzata City Council meeting on November 17. McMillan asked if they plan to put the ditches back as is. Schwarz stated they do. Schwarz stated due to the wetlands in the area, a detailed delineation has been done to replace not only the wetlands as they are but that they will be installing HVP pipe in some sections which does not require a lot of bedding. In addition, the contractor will be backfilling with the excavated dirt. The road will be compacted and will be basically brand-new following the work. McMillan asked if the work will be done through the wetland area. Schwarz stated there is a fine line where the wetland is and where the pipe will be and that they will be skirting the edge of it. Schwarz indicated part of the permit requires that no wetlands be taken away. McMillan noted the trail will stay open to Wayzata. Schwarz stated the trail will not be open in the wintertime but during the summer it will be. McMillan stated the trail is usually not open during the winter. McMillan asked if there is any public comment. A person in the audience asked what will stop residents from using Ferndale to get into downtown Wayzata. Schwarz stated that will not be the official detour but that drivers would be able to do that if they prefer Page 3 of 24
