Recertification for 2026-27 Credit Renewal

Take action in 2025 to recertify credit(s) for your 2026 Stormwater Utility bill. Applicants who received one of the following credits in 2024 will need to recertify their credit type during the next application period, opening November 1, to continue receiving the credit for 2026–2027:

• Conservation Landscaping

• Rain garden

• Rainwater Collection

• Permeable Driveways

A courtesy notice has been sent to those who qualify for recertification of one of the above credit types. Please note: Recertification does not begin until November 1, but new photos must be taken during the summer growing season for conservation landscaping and rain gardens. Review the credit re-certification guidelines in the Credit Manual for information on what must be submitted with your renewal application.

Or did you receive an ongoing voluntary credit (listed above) during the 2023–24 application period and need to recertify this year? We're holding monthly Q&A sessions through October to guide you through the process and answer your questions.

Despite Arlington’s existing lot coverage and stormwater management regulations, impervious area is increasing Countywide, especially in residential areas. Impervious area increases the risk of flooding and extreme heat, which are the two most dangerous weather threats facing Arlington today.

To help mitigate these risks and improve climate resilience, Arlington is considering the adoption of a maximum impervious area requirement in lower density, residentially zoned areas. The County Board has directed staff to study potential amendments to the Arlington County Zoning Ordinance (ACZO) to support Arlington's goals to improve the stormwater system and expand the tree canopy.
