Abstract

Single Member District or SMD's.

Single Member Districts (SMDs) were created pursuant to legislation approving the District of Columbia's "Home Rule" charter in 1973. These neighborhood groups provide the District electorate with "grass-roots" experience in the electoral process. These SMDs boundaries, developed by the DC Council, are based on the 2010 Census of the District's population, with each SMD having approximately 2,000 residents. Representatives elected to each Single Member District sit as Advisory Neighborhood Commissioners. This data set reflects the boundaries approved by the DC Council in May, 2012, for official 2013 SMDs.

All DC GIS data is stored and exported in Maryland State Plane coordinates NAD 83 meters.

METADATA CONTENT IS IN PROCESS OF VALIDATION AND SUBJECT TO CHANGE.

Purpose

SMDs are used for the planning and management of Washington by local government agencies. This specific data set was created for the specific purpose of printing maps of the various SMDs, each on a letter-sized sheet of paper. Boundaries have been digitized with sufficient accuracy for this purpose, and may or may not be sufficiently accurate for other purposes.

For SMDs, 2002 boundaries were used as a starting point. Changes to 2002 boundaries were made using the trace tool on the geographic features referenced in the legislation text (street centerlines, census blocks, lot boundaries, ward boundaries) and merged with/split from the 2002 boundaries. Where the legislation text described boundaries that didn't follow existing features, boundaries were digitized freehand.

Once the smds were finalized, ANCs were constructed by dissolving the SMDs on their respective ANC values.

Distribution

Most DC GIS datasets can be downloaded from "http://dcgis.dc.gov" on the data center page. Orders can also be made by contacting OCTO GIS at "dcgis@dc.gov", especially for datasets not available for download.
