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 Stormwater Utility fee rate for Calendar Year 2025 was 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. The County Board officially adopted the CY 2025 Stormwater Utility fee in April 2025.
