This item was placed on the February 16, 1993, City Council <br /> worksession agenda at the January 25, 1993 council meeting. <br />. As you know, the Council has discussed quarterly rates of $4.95 per residential unit and <br /> $49.50 per acre for commercial and industrial properties. These rates are comparable with <br /> rates in surrounding communities. Based on these rates and infonnation provided by City <br /> Planner Bergly, a annual revenue of approximately $160,000 would be generated. <br /> Following discussions with City staff, however, we recommend that an ordinance which <br /> further refines quarterly rates for residential properties be considered. This ordinance would <br /> more equitably charge properties in various zoning classifications to compute quarterly rates. <br /> We have discussed the attached ordinance proposal with City Attorney Filla, who is of the <br /> opinion that this ordinance is a fairer and more defendable ordinance is meeting State <br /> requirements than charging a flat rate to all residential properties. <br /> Based on engineering principles of stonn water runoff, each type of zoning classification <br /> contributes a different amount of runoff to the City's collection system. We have calculated <br /> an average expected runoff for each zoning district, utilizing accepted engineering standards, <br /> and determined a fee per acre for all developed properties. <br /> The following table lists the comparative amount of runoff for each zoning district. A base <br /> rate is assumed for R-1 properties and all other properties contribute a proportionlltely greater <br /> amount. This proportion is shown as a utility factor. <br />. <br /> 1959 SLOAN PLACE, SUITE 200, ST, PAUL, MINNESOTA 55117 612-774-6021 <br /> 9800 SHELARD PARKWAY, SUITE 102, MINNEAPOLIS, MINNESOTA 55441 612-546-0432 .
