MINUTES CITY COUNCIL September 6, 1989 The City Engineer replied that the storm sewer will follow the property lines, however, the decision has not been made for which side of the property line the storm sewer will be installed. Osland asked where the run-off from the existing shopping center on County Road C goes. The City Engineer replied that that drainage goes into the existing pond. Osland asked if there will be an assessment for the commercial shopping center as part of this improvement. Fahey replied that the shopping center will be assessed for that portion of the drainage that it contributes to the project. Fahey assured Osland that the residential portion of the project will not pick up the assessments for the drainage generated by the commercial property. Virgil Nelson, 70 Iona Lane, reported that there is a natural drainage path from Iona Lane into the existing pond. Fahey commented that there is the need for indepth planning for the drainage of this area. Pantzer asked where the overflow from Round Lake goes. Scalze replied that the overflow from Round Lake ends up in Lake Gervais. Scalze stated that it was her understanding that the overflow system in Round Lake works adequately. The City Engineer discussed the overflow system and reported that there is an 18-inch overflow pipe. Pierce asked how an 18-inch overflow pipe will be able to handle a 20 to 30 inch inlet pipe. The City Engineer explained that the plan from Boosalis's engineer is to run the storm sewer down the property lines into Round Lake and to tie in the existing manholes in the area into this storm sewer. Pierce again reported that the easement on his property is a utility easement only, and is 5 feet in width. Pierce reported that a five-foot easement is not adequate for a storm sewer. Page 7
