On August 1, 2019, the D.C. Policy Center’s article, Single-family zoning and neighborhood characteristics in the District of Columbia, was cited in Greater Greater Washington:
Conveniently, where the framework element says you should build, and where it says you should conserve character, roughly tracks with where in the city you are legally allowed, by zoning, to build more or less housing. The types—neighborhood conservation areas, neighborhood enhancement areas, land use change areas, and commercial/mixed use areas—are visually displayed on the Plan’s Generalized Policy Map.
The Generalized Policy Map also shows similar spatial patterns as where you are required to build single-family homes (which was the subject of a recent DC Policy Center report), where subsidized units have been built, and where one can find life-saving shade.
