What is an Impervious Surface and How is the Fee Determined?
An impervious surface is a surface where rainwater cannot infiltrate into the ground, therefore, creating runoff that eventually flows into a storm drain. Why are impervious surfaces important? Increased areas of impervious surfaces increase the volume of storm water runoff, place a greater load on infrastructure and increase pollutants that flow into our creeks, streams and lakes.
For these reasons, the area of impervious surface on a property is the standard method of assessing a storm water fee. The average impervious area of single-family residential properties in Springfield is 3,465 square feet, based on a review of over 7,000 properties. This 3,465 value is designated as an Equivalent Residential Unit (ERU).
All single-family residences pay a flat fee of $2.00 per month while commercial properties pay a storm water fee based on how many equivalent ERU's of impervious surface that is on their property. For example, a commercial property with 34,650 square feet of impervious surface would pay a fee of ten (10) times $2.00 or $20.00 per month.
Property taxes are based on property value and have nothing to do with the amount of runoff contributed by the property. With a storm water utility, properties pay for storm water based on their runoff contribution. This means that if they contribute more runoff they must also contribute more to managing the runoff. The user fee only applies to properties within the Springfield city limits.
