(A) Classification. For purposes of determining the fee, all properties in the town are classified as follows:
(1) Single-Family Residential Property.
(2) Agricultural Residential Property.
(3) Commercial Property, including but not limited to, the following classifications: AB, OP, NC, LI and Marine District.
(4) Recreation facilities, parks, golf courses, and appurtenances thereto.
(5) Multifamily Property.
(6) Mixed Use Property.
(7) Undeveloped Property.
(B) Base rate. The base rate shall be $60 per year.
(C) ERU. One commonly accepted rate unit for Stormwater Management Program fees is the equivalent residential unit (ERU). This is a descriptive value based on the total gross land area and the classifications of the properties. The ERU is used to relate a rate charged for a typical residential property, and this becomes the common denominator by which all other classifications of properties are evaluated. The town utilizes accepted land use coefficients to relate to the intensity of development. Pursuant to this chapter, an ERU is considered to be a single-family lot less than or equal to 20,000 square feet. The runoff coefficient assigned to the ERU is 0.36. The runoff coefficients assigned to the classifications are as follows:
(1) Single-Family Residential 0.36
(2) Agricultural Residential 0.36
(3) Light Industrial 0.73
(4) Neighborhood Commercial 0.77
(5) Office Professional 0.78
(6) Areawide Business, Marine District, Mixed Use or Recreation 0.86
(7) Multifamily 0.56
(D) Computation of Stormwater Management Program fee and example calculation.
(1) Computation of Stormwater Management Program fee.
(a) Determine rate to assign ERU.
(b) Equate base range (0-.5 ac) of commercial to the ERU.
(c) Assign area ranges for commercial zones.
(d) Calculate ratios for parcels > 0.5 ac based on area.
(e) Using the ratios calculated in (d), multiply by base rate to obtain the yearly fee.
(2) Example calculation. In order to find the fee for 2.75 ac property in an AB zone:
(b) Ratio of AB to ERU 0.86 /0.36 = 2.39. Therefore, a parcel </= 20,000 sf has a ratio of 2.39.
(c) The property (2.75 ac) falls within the assigned area of 2.1-5.0 ac.
(d) Multiply ratio by avg. value for this range: 2.39/.5 x 3.55 = 16.97.
(e) Compute fee based on ERU: 16.97 x $60 = $1,018.20/year.
(E) Stormwater Management Program fee: assigned ratios based on “C” factors and acreage.
Areas of parcels (acres)*
Average areas (acres)

0.51 - 1.0
1.1 - 2.0
2.1 - 5.0
5.1 - 10.0
10.1 - 15.0
15.1 - 20.0
20.1 - 30.0
Parcels larger than 30 ac based on actual acreage.
* Note: Average area within each range is used to determine ratio.
(F) Annual fees. Annual fees for all property, whether occupied or vacant, shall be as follows:
(1) Single-Family Residential Property. Single-Family Residential Property shall be charged a fee equal to the base rate times one equivalent residential unit (ERU), regardless of the size of the parcel or the improvements.
(2) Agricultural Residential Property. Agricultural Residential Property shall be charged a fee equal to the base rate times one equivalent residential unit (ERU), regardless of the size of the parcel or the improvements.
(3) Commercial Property. The intensity of development factor is greater than the single-family unit used as the base ERU because of the amount of impervious area. Pursuant to generally accepted engineering data, the runoff coefficient or C-Factor for commercial property has been determined to be as set forth below in (a) through (e). An equation is used to relate the runoff coefficient of the multi-family property to the base ERU. This equation is then multiplied by the average acreage for the appropriate size range of the property in question. The determined ratio is then multiplied by the base rate to determine the yearly fee. Commercial condominiums that have been assigned a tax map number by the county shall be billed at the base rate.
(a) Light Industrial 0.73
(b) Neighborhood Commercial 0.77
(c) Office Professional 0.78
(d) Areawide Business, Marine District, Mixed Use or Recreation 0.86
(e) Multifamily 0.56
(4) Undeveloped Property. Undeveloped Property shall be charged one-half of the ERU base rate. Pursuant to generally accepted engineering data, the runoff coefficient is approximately one-half of the runoff coefficient for the ERU definition stated herein.
(5) Recreation facilities, parks, golf courses, and appurtenances thereto. Recreationfacilities, parks, and golf courses shall be charged one-half of the ERU base rate for each individual tax parcel. Clubhouses, tennis and pool facilities, and appurtenances thereto shall be billed at the appropriate AB rate as previously defined in this section under division (E).
(G) Minimum fee.
(1) All dwelling units within the town that have been assigned a tax map number by the county shall be charged the base rate multiplied by one ERU.
(2) All non-residential/commercial property within the town that has been assigned an individual tax map number by the county shall be charged a minimum fee based upon a parcel size of less than one-half acre within the applicable zoning classification, or a fee based upon an actual calculation as prescribed by this chapter, whichever is greater.
