Arlington’s Stormwater Utility is still in development. The information reflected on the Fee Estimator is not final and is for illustrative and informational purposes only. 

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

The proposed rate for one ERU is $258 per year. 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. There will be a public hearing at the Dec. 16, 2023 Board meeting before the Board officially adopts the utility, ordinances, and sets the Calendar Year 2024 utility rate.
