   (B)   One ERU shall, for the purposes of this section, have an assigned value of 1.00. One ERU is hereby established and determined to be equal to a flow of 300 gallons per day (300 GPD), average annual basis. The "Total Equivalent Residential Unit Value" for an establishment shall be calculated by multiplying the ERU factor listed in division (A) above times the number of units.
   (C)   For all establishments not listed above, the total ERU value shall be determined by multiplying the number of fixture units, as published in the Florida Plumbing/Building Code, by 25, and then dividing that numerator by 300 GPD/ERU. For example:
Total = Number of fixture units x 25
ERU value    300
In no event shall the total ERU value used to calculate a sewer impact fee, when using this method, be less than 1.00, nor less than the volume determined to be required by Seminole County.
   (D)   If the Public Works Director determines that the actual sewage usage will be greater than the ERU usage assigned to such category as set forth above, then the Director may determine, based on actual usage, anticipated usage, peak load requirements, or any combination of the foregoing using accepted engineering standards, a different or greater total ERU value. Notice of any such determination shall be sent to the City Commission.
