This page has information about the Land Disturbing Activity/Stormwater permit requirements for building projects. Please note that the requirements for the LDA permit were updated in September, 2021.
The County adopted a new Stormwater Management Ordinance, Chapter 60 in response to comprehensive new Virginia stormwater regulations which became effective in 2014.
Stormwater management plays a major role in Arlington’s efforts toward flood resiliency.
Do I Need a LDA/SWM Permit and How Do I Obtain One?
You will need a Land Disturbing Activity/Stormwater permit for your project if the total disturbed area is 2,500 square feet or more. (How do I calculate land disturbance area?)
- If your total disturbed area is less than 2,000 square feet, you do not need a LDA permit.
- If your total disturbed area is between 2,000 and 2,499 square feet, you may need to obtain a survey of the disturbed area with survey markings on your site to ensure it’s not larger than 2,500 square feet.
