The storm water utility is based on two different items.
- First is the impervious area in square feet to be billed. The impervious area of a parcel is any area where rain water cannot penetrate the ground (grass, dirt, gravel areas). Examples of impervious areas would be parking lots, driveways, concrete slabs and the structure itself. This area is measured and billed in square feet. All of these areas require the rainwater to runoff into the storm sewer instead of being absorbed into the ground.
- Second is the number of days in the billing cycle.
Residential properties are billed a flat rate over 365 days. Business customers are billed $.0363 cents per square foot of area over a 365 day span. So if the billing period is 89 one quarter, and 93 the next the amounts will vary.
