D.C. Mun. Regs. tit. 10-A, § 1602
1602.1 Statistics on existing land use are estimated using current lot-by-lot property tax data and information on housing units, employment, District and federal land ownership, parks, roads, water bodies, and other sources. They are not comparable to the statistics included in the 2006 Comprehensive Plan, which were based on a much simpler method. Even large differences between the older and newer statistics may reflect differences in the modelling approaches, used a decade apart, and not actual changes in land use. Land use statistics for the Planning Area appear in Figure 16.1. Central Washington comprises about 3,285 acres, or about 7.5 percent of the District. About 510 acres of the total area consists of water.

1602.3 Compared to the other nine Planning Areas in the city, Central Washington contains much higher percentages of commercial, mixed-use, and federal land. Commercial and mixed-use land represent 14.6 percent of the total. Non-park federal land represents 19.9 percent of the total. Much of this land is also developed with offices, but the owner and occupant is the federal government.
1602.4 Approximately 33 percent of the Planning Area consists of transportation rights-of-way One-quarter of the land area is parks, recreation, and open space, and the portion allotted for this is slightly higher than Washington, DC's total of 22.7 percent. Much of the open space is contained within the National Mall and almost all of the remainder comprises federal reservations managed by the National Park Service (NPS). The federal open space has significant programming restrictions, limiting its use for local purposes and District activities.
1602.5 Residential land (land that is only residential and not mixed-use) comprises just 1.7 percent of the Planning Area. Almost all of this acreage consists of mid- to high-rise apartments, with average densities exceeding 100 units per acre. The area features this low percentage because most residential developments in Central Washington also include non-residential uses within their buildings, making them mixed-use developments, which are counted under the commercial and mixed-use category. Most of the residential development is located in Dupont Circle along the Massachusetts Avenue NW corridor, Mount Vernon Triangle, and NoMa. Another concentration is located in Penn Quarter, around 7th and D Streets NW.
1602.6 The percentages of land area for other uses—or example, institutions, public facilities, and utilities—are all relatively small. Only about 1.4 percent of the Planning Area consists of vacant, unimproved private land.
1602.7 Much of the land in Central Washington is publicly owned. Government uses—classified as federal, local public (i.e., District-owned land), and transportation rights-of-way—represent just over 57 percent of the total land uses in Central Washington.
