CHAPTER 2. DEVELOPMENT OF CAPACITY CHARGES <br />The actual calculation of capacity charges for non - residential (commercial or industrial) customers <br />is performed by the City using the methodology shown in Table 2 -6. <br />It is recommended that the City update its methodology for the calculation of capacity charges to <br />allow for the determination of gallons per day based on all data supplied at the time of plan check <br />of construction documents rather than on the two choices for "per person" square footage and <br />gallons shown in Table 2 -6. For example, if a 200 -seat restaurant applies for connection to the <br />sewer system, the City may require that the applicant supply wastewater discharge data for other, <br />similar restaurants or the City could determine the wastewater discharge data based on evaluation <br />of discharge characteristics for other, similar restaurants already discharging to the City's system. <br />Table 2 -6.
