If you are an existing customer look at your bill and take the amount billed and divide it by $4.98 to determine the number of stormwater ERU's. If you are not an existing customer, your ERU's are based upon the number of square feet allotted to you by the landlord, divided by 2651 sq. ft. per ERU.
You leased a 3,000 sq ft space. As per your type of business you are allotted five parking spaces. This is equal to 1,000 sq. ft. of parking (5 spaces x 200 sq ft / space).
