The permit application shall be supplemented by any plans, specifications or other information considered pertinent in the judgment of the city.
(Prior code § 51.33)
A. 
Capacity Requirement. Prior to city's final approval of improvement plans, authorization of any sewer service connection, issuance of a building permit, or issuance of a final inspection certificate for development, the applicant shall acquire or secure sufficient allocated sewer capacity for the property based on projected discharge, as calculated by the city engineer. The applicant shall pay all connection fees, capacity fees, and reimbursements determined by recorded consumption volumes or estimated capacity needs, calculated by the city engineer in accordance with the City's then-applicable Fee Schedule, City Standards, implementing resolutions, and city regulations. No permit or certificate described in this subsection shall be issued until such fees are paid and adequate allocated sewer capacity is acquired or secured.
B. 
Monitoring, Audits, and Records. The city may monitor and audit metered sewer discharge, water-use-to-sewer conversion records, and other relevant documentation at any time to determine average daily discharge and confirm compliance with allocated sewer capacity. The city may require submittal of usage records, meter readings, flow monitoring reports, building occupancy and fixture counts, or other data reasonably necessary to implement this section. The city may inspect meters, flow monitoring devices, service connections, or on-site collection facilities during normal business hours, or at other reasonable times to verify actual discharge.
C. 
Exceedance, Mandatory Acquisition, and Cure Period. Any discharge that causes average daily discharge to exceed the property's allocated capacity is a violation of this chapter. Upon written notice of violation, the property owner shall, within 30 calendar days, either:
1. 
Secure sufficient additional allocated capacity to eliminate the violation by purchasing city-owned capacity or securing an approved private capacity transfer as allowed under subsection D; or
2. 
Implement and document operational or structural changes (including, but not limited to, flow reduction measures, fixture changes, or on-site storage/treatment acceptable under this title) to reduce average daily discharge to at or below allocated sewer capacity.
If the applicant demonstrates to the satisfaction of the city engineer that additional capacity cannot be procured within the 30-day period despite good-faith efforts, the city engineer may grant a limited-time extension to allow the city sufficient time to make capacity available for purchase. The extension is not automatic and is subject to approval of the city engineer.
D. 
Private Capacity Transfers and City Facilitation. The owner may acquire required capacity from the city or via a transfer or sale of an existing allocated capacity right from a private third property owner, subject to city engineer approval and this chapter. Private capacity transfers must be documented in a form approved by the city, comply with applicable state law and city policies, and be recorded as required by the city. The city may require verification that the transferred capacity does not cause noncompliance at the donor property.
E. 
Fees, Objective Determinations, and Role of the City Engineer. All capacity fees, surcharges, and calculations shall be made in accordance with the City's Fees Schedule, City Standards, and implementing resolutions. The city engineer's determinations under this section shall apply the City's Standards and Fee Schedule. Where the calculation methodology requires judgment in unit conversion or unusual cases, the city engineer shall apply documented, objective criteria and shall briefly state the factual basis for any nonroutine calculation in the administrative record.
F. 
Enforcement and Remedies. Violations of this section may result in penalties, surcharges, administrative fines, permit denial, suspension of sewer service, or other enforcement measures as provided in this title and Chapter 1.12. The city shall follow all required notice and hearing procedures prior to any suspension of service. In addition to fines and surcharges, the city may record a notice of noncompliance against the subject property and seek injunctive and other legal relief as appropriate.
