3. Regional Wastewater SDCs For All Existing'Development <br />Regional Wastewater SDCs For Existing .Single-Family DweNin~s and <br />Duplex Development <br />For existing single-family dwellings, the regional wastewater SDC collected <br />is;equal to the rate. for one EDU: For all duplex development, the regional <br />wastewater SDC collected is equal to two times the rate for one EDU. <br />' Regional Wastewater SDCs For All Other Existing Development with <br />Annual Average Daily Flow less than 100,000 Gallons <br />Foradministrative convenience, rather han verifying by physical inspection <br />the' number of .plumbing fixture units in an .:existing development -that is <br />.connecting to the wastewater system for the .first time, the regional <br />wastewater SDC collected shall be determined by using the average historic <br />winter water. consumption .for the existing development. The existing <br />development's historic consumption. is calculated by averaging the actual <br />- winterwater consumption, in gallons, for the preceding months of December <br />through April, dividing the resulting number by 1,000, and multiplying by the <br />rate for historic consumption. The rate for historic consumption (per 1,000. . <br />gallons) is based on an assumed typical. single-family dwelling average <br />winter water consumption of 6,000- gallons per month.... <br />Regional Wastewater SDCs For All Other Existing .Development with <br />Annual Average Daily Flowfqual to or Greater than 70.0,000 Gallons <br />For existing development with measured annual average daily flow equal to <br />or greater than 100,000 gallons of water discharged, the regional <br />wastewater SDC collected is equal to the total amount of water being <br />discharged per. day, divided by the EDU standard 200 gallons per day, <br />multiplied by the rate for orte EDU. The regional wastewater SDC charge <br />will be based on the greater of calcula#ions using either the. City <br />methodologies oi- the current MWMC Equalization Fee.. charge.. <br />4. ,Regional Wastewater Administrative Charge <br />A further adjustment to the regional wastewater SDC is the addition of - <br />administrative costs: MWMC will: incur staff costs for the tipdating and processing <br />of the charge. These costs would be applied on a per connection basis. The <br />.administrative cost per permit is calculated, based. on estimated administrative <br />costs and future connections. The Regional Wastewater Administrative Charge per <br />permit is applied to the total SDC fees after all other charges.and credits have been <br />applied. <br />Exhibit B to Administrative Order.
