DC Council has been working for years to update the Comprehensive Plan, DC’s enormous zoning and land-use document. On Tuesday, those years of work concluded in a unanimous vote on an update to the document, which dates back to 2006. The Comprehensive Plan doesn’t change DC’s zoning, but it does guide decisions about land use and zoning, shaping the direction of DC’s growth, including some in historically exclusive neighborhoods west of Rock Creek Park. Density advocates (including some at GGWash), as well as Mayor Muriel Bowser, say boosting DC’s housing construction is vital for addressing housing affordability. Planning director Andrew Trueblood told the Post the amendments could allow for increasing housing stock by as much as 15%.
