How Your Local Stormwater Fee is Calculated
The Stormwater Services Division is funded by a stormwater utility. Customers are billed for stormwater runoff based on the Equivalent Residential Unit (ERU). An ERU (Equivalent Residential Unit) is the average impervious surface area found on a single-family residence. Impervious surfaces are any built-upon areas, such as rooftops, sidewalks, and driveways that impede the natural infiltration of water into the soil. The impervious surface area (ISA) was calculated for residential properties throughout High Point using aerial photographs. The ERU (Equivalent Residential Unit) for High Point was determined to be 2,588 square feet.
