The Stormwater Utility billing unit, or Equivalent Residential Unit (ERU), is 2,400 square feet of impervious area (IA). This is the median IA on Arlington County residential parcels. 

The utility fee rate for Calendar Year 2024 is set at $258 per ERU. Your stormwater utility fee is calculated by the number of ERUs on your property multiplied by $258. Note that the utility fee is based on a cost recovery model, so it is dependent upon the adopted budget each year.
