A. 
Fee Resolution. The City Council has the authority by resolution, to establish fees when necessary to recover the costs for sewer services.
The City of Carlsbad Fee Resolution shall provide for a sewer service charge to be charged monthly to dischargers. The sewer service charge shall incorporate all costs of sewage collection, treatment and disposal, including administrative and general expenses. The charge shall be based on four cost components:
1. 
City operations and maintenance;

City capital requirements;
3.

4. 
City's portion of costs associated with EPIC capital requirements.
B. 
Allocation of Costs.

Group I residential dischargers shall be charged a flat rate amount per billing period. The flat rate amounts for multiple-family housing shall be administered according to the number of residential units per water meter.
All other discharger groups shall be charged a unit rate per hundred cubic feet (HCL) of water usage or a minimum charge, whichever is greater. Each discharger group shall have a separate unit rate per hundred cubic feet of water usage or minimum charge, whichever is greater. Each Group VI large volume discharger shall have a separate unit rate per hundred cubic feet of water usage or a minimum charge, whichever is greater. The City of Carlsbad fee resolution shall stipulate the unit rates and minimum charges based on wastewater quality and quantity.
Schools shall be charged on the basis of average daily attendance (ADA). The sewer service charge shall be applied throughout the 12-month year.

The same enforcement provisions shall apply to the collection of such fees pursuant to this chapter.
(Ord. NS-143 § 4, 1991)
A. 
Filing for an Adjustment of Charges. In any case where it is believed that a sewer service charge imposed by this article is excessive, the person responsible for paying such charge may apply to the Director for adjustment by filing with the Director, within 30 days from the date of service of such charge, a written dated affidavit containing:
1. 
A description, or address of the property involved in the requested adjustment;
2. 
The name or names and mailing addresses, of all the appellants participating in the requested adjustment;
3. 
A brief statement setting forth the legal interest of each of the appellants in the building or land involved in the requested adjustment;
4. 
A statement in ordinary and concise language describing the reason for the requested adjustment;
5. 
A statement of any material facts supporting the request for adjustment; specifically, statements alleging discriminatory, unreasonable, or unfair charges.
B. 
Determination. As soon as practical, but not longer than 60 days after receipt of request for adjustment, the Director shall make a determination concerning the request for adjustment.
The charge shall be deemed to be nondiscriminatory, reasonable, and fair for a nonresidential user if at least 90% of the water supplied to the premises on an annual basis enters a public sewer.
The charge shall be deemed to be discriminatory, unreasonable, or unfair if the wastewater characteristics of the discharger indicate that the discharger should be assigned to a different discharger group, as defined herein.
During the course of the request the Director may visit and inspect any building or premises involved in the proceedings, and may there receive oral testimony of any witness.
The findings of the Director may wholly, partially, conditionally, approve or disapprove the requested adjustment. The decision of the Director may be appealed to the City Council by filing a written notice of appeal with the City Clerk within 10 calendar days of the Director's decision. Fees for appeal shall be established by resolution of the City Council.
If it is determined that the charge is discriminatory, unreasonable or unfair, the Director shall adjust the charge so that it is fair, reasonable and nondiscriminatory. If the charge has already been paid, the excess paid during the year immediately preceding the date of application for adjustment shall be refunded. Charges which are delinquent for more than 90 days shall not be subject to adjustment.
