Arlington’s stormwater program through Dec. 31, 2023 was funded through a Sanitary District Tax based on a property’s assessed value. The final stormwater fee was set at $0.017 per $100 of assessed value. An average property had paid about $136 per year under the sanitary district tax. However, a property’s assessed value didn't correlate well to the amount of runoff a property generates.
Arlington’s stormwater programs are part of the Office of Sustainability and Environmental Management in the Department of Environmental Services including water quality regulations, planning, engineering, construction, stormwater infrastructure, and incentive and outreach programs.

The Virginia Department of Environmental Quality issues permits for the discharge of stormwater into waterways like Four Mile Run and the Potomac River. These permits, called municipal separate storm sewer system (MS4) permits, are good for five years. Arlington’s current MS4 permit (VPDES Permit No. VA 0088579) was issued on July 1, 2021.
The previous Sanitary District Tax and the current Stormwater Utility fee generate all of the funding to support these programs. The Stormwater Utility fee is calculated on a cost recovery basis – fees are set to generate the necessary revenue for the stormwater management program.
