[Added by Ord. 75-13]
The size and grade of each public sewer must be such as to provide at all times sufficient capacity for peak flow rates of discharge. In order to establish estimates of sanitary sewage at peak flow, each applicant for a building permit shall submit plans of intended construction and such information as the City Engineer may require on printed forms provided for the purpose. The following table is established as the peak flows for the various occupancies and shall be used as a basis for computing the discharge rate to the public sanitary sewer.

Any occupancy not contained within the aforementioned classification shall be rated by the City Engineer at a peak flow based upon any aforementioned classified occupancy it most nearly resembles. Until the City Council, based upon further engineering studies, determines excessive peak flow discharge for single family residential property, all single family residential property shall be classified at 600 gallons per day per dwelling unit, provided, however, any single family classification, having in addition to a single family use on each 5,000 square feet of lot area an accessory use discharging sewage to the public sewer, shall be classified for the purpose of this Chapter as a multiple dwelling.
The peak flow to the sanitary sewer for a building containing mixed occupancies shall be determined by adding the peak flow characteristics of the various occupancies as set forth in the above table.
The aforementioned Table of peak flows is based upon the Sanitary System Study prepared by the City Engineer using engineering criteria and mathematical formulae in determining the existing sewer capacity, needed sewer reconstruction by discharge over and above existing sewer capacity, and the cost and scheduling thereof. As the result of said study, the City Council hereby finds and determines that the total cost of reconstruction as set forth in said Sewer Plan will beat the rate of 15 cents per gallon per day of additional peak flow in excess of 600 gallons, which rate shall be modified periodically to reflect any change of lot area per day shall be used in determining the charge to be imposed for the purpose of this Part at the rate of 15 cents per gallon per day.
The applicant for a permit to connect any tributary area to a public sewer shall declare all information necessary, as determined by the City Engineer, to comply with the provisions of this Chapter, and shall pay the rate provided herein, excluding credit specified in Section 5073.3, provided that the City Engineer determines there is sufficient capacity available or can be made available in the public sewers to serve the anticipated development. Any area study to determine capacity shall be made by the City Engineer, or by a registered Engineer under his approval, and the cost thereof shall be borne by the applicant.
If sufficient capacity is not available or cannot be made available in the public sewer, said connection may not be made unless otherwise authorized by the City Council.
The charges collected under this Chapter shall be credited to the Sewer Reconstruction Fund. Monies deposited in the Sewer Reconstruction Fund shall be expended for the purpose of reconstructing the public sewer system as set forth in the Sanitary Sewer System Study on file in the office of the City Engineer, or as hereafter modified or amended by the City Council. All engineering costs, refunds as provided herein, mileage, overhead, incidental and construction costs necessarily incurred in the reconstruction of sewers shall be charged to the Fund, to the extent allowed by law. Reconstruction, as used in this Chapter, shall include the acquisition and construction of public sewers as defined in Section 5071.4 or as authorized and subject to Section 5471 of the Health and Safety Code of the State of California.
In the event any person shall have paid the applicable sewer reconstruction charge based on the additional peak flow created by new construction as provided herein, and no portion of said new construction shall have been commenced, and the permit for such construction shall have been canceled or expired, said person shall be entitled, upon written request, to a refund in an amount equal to 100% of the sewer reconstruction charge paid by said person minus 1% of said charge for administrative handling. However, the amount retained shall not exceed $10.00.
In accordance with the Sanitary Sewer System Study, aforementioned, the City Council hereby finds and determines that there are certain critical areas within the sewerage system which are overloaded, as set forth on Appendix C of that certain report entitled "Sanitary Sewer System Study" of the City Engineer. Where the City Engineer hereafter determines in any such critical area that further construction will result in sewage being disposed in the sewer lines of said area in excess of the capacity available to handle said sewage, to the point that said sewage may back up or overflow, creating a hazard to the public health, the City Engineer shall so certify in writing such a determination and finding to the City Administrator and thereafter no building permit shall be issued for any building or structure within said area until the City Engineer has certified a sufficient capacity is available in said public sewer or can be made available before the building is occupied. If any owner, in order to obtain sufficient capacity for a sewer, shall, with approval of the City Engineer, reconstruct public sewers as herein defined, said owner shall receive as a credit against the payment of any sewer reconstruction charge an amount equal to the cost of such reconstruction not subject to reimbursement as otherwise provided in this Division.
