Notes:
1 If more than one use category is applicable to a particular building, the building will be divided into areas of similar use categories and the ERU units for the building will be computed by adding the ERU units determinations for each use category area. For uses not specifically described in this schedule, the number of ERU units to be assigned shall be determined on a case-by-case basis by the wastewater treatment plant operator and approved by the town council. No less than 1.0 ERU unit will be assigned any building or portion thereof that has a separate side sewer.
2 In computing area, the "total usable area" shall be used. "Total usable area" includes but is not limited to: kitchen areas, serving areas, washing areas, occupant areas, waiting rooms, storerooms, restrooms, lunch rooms, halls, entryways, showrooms and retail areas.
3 In computing the number of fuel nozzles, the town will only count the number of nozzles that can dispense fuel at the same time. For the purposes of this schedule, fuel includes all types of gasoline and diesel fuel.
4 For the purpose of gas station/retail store combinations, the retail space assessed at the retail store square footage rate shall be equal to the total retail space less four hundred (400) square feet or zero, whichever is greater. This adjustment is to account for the estimated retail space of a gas station without any general retail space.
5 A residential building or portion thereof shall be considered multifamily if it has more than one kitchen area, except for those multifamily units meeting the definitions and standards for co-living, single-room occupancy, or micro-apartment buildings in Title 17, Zoning.
