A. Service Fees Imposed: The city will, by resolution of the city council, impose storm drainage fee rates and charges on each parcel of real property within the city, except governmentally owned streets. The charges shall fund the administration, planning design, construction, water quality programming, operation, maintenance and repair of existing and future stormwater facilities.
B. Method Of Determining Contribution Of Stormwater:
1. Contributions of stormwater from nonresidential parcels and residential parcels larger than duplexes have been ascertained by evaluating land surface and measuring the amount of impervious surface.
2. Contributions of stormwater from residential parcels up to and including duplexes have been ascertained by sampling the amount of residential impervious areas.
C. Classifications: Storm drainage service fees shall be assessed on each parcel of real property within the city (including city owned properties), except government owned streets and city stormwater facilities. Service fees shall be established by resolution of the city council and may be differentiated according to the following classifications:
Residential parcels: Single-family residential and duplex parcels shall constitute one ERU per month.
Undeveloped parcels: Undeveloped parcels shall have no charges assessed.
Other parcels: Charges for all other parcels shall be computed by multiplying the total ERUs for a parcel by the monthly rate. Total ERUs are calculated by dividing total square feet of impervious surface by three thousand nine hundred (3,900) (1 ERU), rounded to the nearest whole number.
Credit for on parcel mitigation: Nonresidential parcels with mitigating stormwater facilities, e.g., approved on site detention/retention of stormwater, approved discharge of stormwater through a sewer connection or other approved and complete on site detention methods that meet the city design and maintenance standards may be eligible for a service fee credit. The parcel's owner or agent must make application for this credit to the city engineer. The amount of credit is based on the following formula:
P = 50 + 50 (Qr/Qp)
Formula symbols have the following meaning:
P = Percentage of storm drainage fees to be applied to the parcel
50 = Percentage representing utility's fixed operation and maintenance costs
50 = Percentage representing costs for utility's capital improvement program
Qr = Restricted stormwater discharge from a parcel
Qp = Peak stormwater discharge from the same parcel that would result if the mitigating facilities were not in place.
The city engineer may, if requested, provide a complete on site mitigation evaluation at the expense of the parcel owner or authorized agent.
Credit for regional stormwater mitigation: Nonresidential parcels with mitigating stormwater facilities that serve the city regional stormwater needs as prescribed by the stormwater master plan and utilizing methods that meet the city design and maintenance standards, may be eligible for a service fee credit. The credit may be granted if property owners have not already been compensated for or agreed to construct the facilities as part of the development process. The parcel owner or agent must make application for this credit to the city engineer.
If a request for mitigation credit is granted, the credit shall be applied to all charges from the time of the appealed billing, and will be reflected on the next billing thirty (30) days after appeal is granted.
Low income relief: A single-family residential parcel owner who qualifies for the city low income relief, as determined by resolution of the city council and set forth in the fee schedule, may also be eligible for a reduction in the service charge for their parcel. (Ord. 2016-12, 8-16-2016)
