GAR overview
What is GAR?

The Green Area Ratio is an environmental sustainability zoning regulation that sets standards for landscape and site design to help reduce stormwater runoff, improve air quality, and keep the city cooler.

For additional information, please contact Markku McGlynn at markku.mcglynn@dc.gov or at (202) 535-2242.

For questions regarding the development of the GAR regulation, refer to the Office of Planning.
