Surface Water Manangement Utility Division I. Generally SECTION 28-162 GENERAL OPERATION: The Municipal Surface Storm Water Runoff system shall be operated as a public utility (hereinafter called the surface water management utility), pursuant to Minnesota Statute Section 444.075, from which revenues will be derived subject to the provisions of this Chapter and Minnesota Statutes, . SECTION 28-163 DEFINITIONS: A. Utilit' Factor. The utility factor is defined as the ratio of runoff volume, in inches, for a particular land use, to the runoff volume, in inches, for a 1/3 acre residential lot, assuming a 2" rainfall and Soil Conservation Service (SCS) "Type B" soil conditions. B. Surface Water Manal1:ement Fee. The surface water management fee is defmed as the quarterly charge developed for each parcel of land pursuant to City regulations and zoning classifications and shall be established by City Council resolution. C. Quarterly Surface Water Manal1:ement Utilit' Budl!et The quarterly surface water management budget is the estimated quarterly expenditures for planning and inventories, capital expenditures, personnel and equipment and operation of the surface water utility, in accordance with established City policy. This budget shall be established from time to time by City Council resolution. SECTION 28-164 ESTABLISHMENT OF FEES . Surface water management fees shall be established by City Council resolution. The following steps are taken to determine the quarterly fee to be charged to each property: otdin04-2 1 of 5 . .. 3 a) A calculation is made of the total area, in acres, of property zoned R-1, R-2, R-3, . R-4, 1-1, 1-2, B-1, and B-2 within the City. b) A determination is made whether each individual property within these zoning classifications is developed or undeveloped. c) The total number of developed acres of property within these zoning classifications is calculated. d) The total acreage of developed property zoned as R-1, single family residential, is divided by the total acreage calculated in step c. This yields the percentage of total developed property that is zoned R-1. e) The City Council establishes, by resolution, the quarterly budget for the revenue to be generated. f) The portion of the quarterly budget to be charged against properties zone R-1 is calculated by multiplying the percentage found in step d. by the budget amount in step e. g) The rate per acre for property zoned R-1 is calculated by dividing the revenue for R-1 properties in step f. by the total acreage of developed properties found in step . c. This rate is the basis for all rates charged to any other zoned properties within the City. h) The volume of storm water runoff is calculated for all properties zoned R-I, R-2, R-3, R-4, 1-1, 1-2, B-1, and B-2. The methods used for these calculations follow the U. S. Department of Agriculture Soil Conservation Service guidelines for soil types common to Arden Hills. A curve number is chosen for each zoning classification, which is an approximate measure of the percentage of impervious surface on the property. The volume of runoff for each zoning classification is the calculated using the following equation. Q = CP-0.2S)2 P + O.SS Where Q = runoff, cfs S = (lOoo/cn) - 10, dimensionless P = 2, inches i) The runoff value calculated in step h. for R -1 properties is considered the base rate. The runoff value for each of the other zoning classifications is then divided by the base rate to yield a utility factor for each zoning classification. This utility . factor is a measure of the additional runoff created from the property as compared to a single family lot. The utility factors for each zoning classification are listed in the following section of this ordinance. ordin042 2 of 5 ~ - j) The rate per acre for all zoning classifications, except R-l, are calculated by multiplying the utility factor found in step i. by the base rate determined in step g. SECTION 28-165 FACTORS FOR DETERMINING FEES FOR VARIOUS LAND USES: The utility factors for various land uses used to determine the surface water management fees are assigned as follows: Zoning: Districts Land Use Utility Factor R-l Single-Family Residential (1\3 acre lots) 1.00 R-2 Single and Two-Family Residential (114 acre lots) 1.31 R-3 Townhouse and Low Density Multiple Dwellings 2.72 R-4 Multiple Dwelling 2.72 1-1,1-2 Limited and General Industrial 4.25 . B-1, B-2 Limited and General Business 4.25 SECTION 28-166 ADJUSTMENT OF FEES The City Council may adopt policies, by resolution, for adjustment of the surface water management fees. Information to justify a fee adjustment must be supplied by the property owner. Surface water management fees will be adjusted under the following conditions: a) Revision of Quarterly Surface Water Revenue - The estimated expenditures for the management of surface water shall be revised at a frequency specified in the ordinance. The fees will be adjusted accordingly and will follow established City procedures for this adjustment of utility (water and sewer) rates. b) Changes in Developed Conditions of Parcels c) Storm Water Retention - If it can be demonstrated that an individual parcel retains all or a portion of the rainfall that it receives, the surface water management fee will be reduced by a percentage equal to that percent of the parcel which produces no external runoff. A fee reduction of 20 percent or greater must be demonstrated. . ordin042 30f5 -------- .. . SECTION 28-167 UNDEVELOPED LAND Undeveloped properties, without regard to zoning classification, shall be assessed at one-half the rate, charged to developed property zoned as R-l. SECTION 28-168 EXEMPTIONS The following land uses are exempt from the surface water management fee: (a) Public Right-of-Way (b) Lakes (c) Parks SECTION 28-169 MAILING STATEMENT OF CHARGES Statements for the preceding quarterly Surface Water Management service shall be mailed to each customer pursuant to the same procedures as listed under Section 28-57 of this code.
