Elk River City Council Meeting October 25, 1993 Page 7 e opportunity to install conduits for future extension of sanitary sewer and watermain to the East Highway 10 corridor in conjunction with MnDOT's project. He indicated that staff is therefore recommending that the issue of conduits for future sanitary sewer and water extensions be dropped at this point. Terry Maurer indicated that the comprehensive drainage plan calls for a 72 inch diameter storm sewer line from the railroad line through the MnDOT interchange to the Mississippi River. Terry Maurer stated that MnDOT's final design of the Trunk Highway 10/101/169 interchange does not provide enough elevation difference to install a 72 inch diameter culvert. He further indicated that in order to get comparable capacity in a smaller size culvert, three parallel 42 inch diameter culverts would need to be installed. He indicated that this would be much more costly than the installation of one larger diameter pipe. He stated that the cost would be between $525,000 and $600,000. Terry Maurer further indicated that if the City decided to install only one 42 inch culvert to save money, the affect would be increased ponding requirements upstream. He further indicated that it is unlikely that the DNR and Army Corps of Engineers will allow this amount of ponding. He recommended that the City proceed through MnDOT to include the three 42 inch diameter pipes in the MnDOT project with the option to eliminate one or two of them depending on the construction costs. e COUNCILMEMBER HOLMGREN MOVED TO INCLUDE THREE 42 INCH DIAMETER PIPES IN THE MNDOT PROJECT WITH THE OPTION TO ELIMINATE ONE OR TWO OF THEM DEPENDING ON CONSTRUCTION COSTS. COUNCILMEMBER SCHEEL SECONDED THE MOTION. THE MOTION CARRIED 5-0. 4.10. Discussion on Policy for Storm Sewer Fees Related to the Comprehensive Storm Drainage Plan City Engineer Terry Maurer stated that staff is currently working on developing a storm water utility fee which will generate money to be utilized for storm sewer improvements by providing for a monthly or quarterly charge. Terry Maurer stated that the only other funding mechanism available for these types of improvements would be assessments to the benefitted properties. Terry Maurer indicated that the City Council should consider the appropriateness of a potential assessment fee on an area basis for developing properties. The Council should also determine at what level the rates should be set. After further discussion it was the consensus of the Council to authorize the City Engineer to research other cities and developments and bring a recommendation back to the City Council. Mayor Duitsman informing them assessments. requested staff to send a memo to Elk River Utilities of the possibility of billing for storm sewer 4.11.
