Administrative Component + ((Revenue admingen /12) / Number.General.Customers) Street Component = + (Revenue streetres /12) / Number.Residential.Customers) Monthly Fee for General Commercial/Industrial Customer = Quantity Component + Quality Component + Administrative Component + Street Component where, Quantity Component = (((Revenue quantity/12) / ESU total) * ESU customer) Quality Component = (((Revenue quality/12) / ESU weighted) * ESU customer * Quality.Factor) Administrative Component + ((Revenue admingen /12) / Number.General.Customers) Street Component = + (Revenue streetcomind /12) / ESU comind) Where: Quality.Factor = a function of one or more attributes such as land use, lot size, basin, etc. This function is equal to 1 under the current method for allocating water quality costs since the water quality-related programs are provided for all customer categories. ESU weighted = Sum of all customers' (ESU customer * Quality.Factor) = ESU total when Quality.Factor = 1 5.2.1 Calculating The Number Of ESUs Belonging To A Customer ESUs are calculated differently for general stormwater customers than for small and medium residential customers. To calculate the number of ESUs belonging to a general stormwater customer, divide the amount of the customer's impervious surface area by 1,000, the resultant being the number of ESUs. If the result is a number with a decimal or fractional element, truncate to the whole number. For example, if a restaurant has 15,670 square feet of impervious surface, then the restaurant has 15,670/1,000 = 15.67 = 15 ESUs. Thus, every additional 1,000 square feet of impervious surface represents an additional ESU. A customer with 1,000 to 1,999 square feet of impervious surface has 1 ESU; a customer with 2,000 to 2,999 square feet of impervious surface has 2 ESUs, etc. The minimum number of ESUs a customer can have is 1. So, customers with 1 to 1,999 square feet of impervious surface are automatically assigned an ESU of 1. See Figure 3. The number of ESUs for the two residential categories is calculated differently than ESUs for general stormwater customers. Most residential customers fall into the small or medium residential category depending on the size of their estimated building foot print. If the customer's building footprint plus garage/carport area is 1,000 square feet or less, the customer falls into the small residential category. If the customer's building footprint plus garage/carport area is between 1,000 and 3,000 square feet, the customer falls into the medium residential category. See Figures 1 and 2. While building foot print determines which category a residential customer belongs in, the amount of the fee will be based on the amount of total impervious surface on a typical property within a category.
