Why is impervious area used to determine the fee?
The amount of stormwater runoff originating from individual properties is significantly increased by the amount of impervious area on each property. Impervious area consists of houses, buildings, and other structures; driveways, patios, parking lots, and other manmade surfaces that do not allow precipitation to infiltrate into the ground. Pervious surfaces include grass, pasture, crop land, and most undeveloped land. Impervious surfaces decrease the amount of infiltration into the ground and increase the amount of runoff that will enter the City’s stormwater system. The rate structure does take into account density (the percentage of impervious area on a property) when calculating the fee. Properties of similar size with lower density percentages pay less than those with higher percentages.
