Parking Blockface

Parking zones created from collected sign data throughout Washington DC. Parking Zones are created between two parking restriction signs of the same type that point at each other, or between a sign and an intersection.

Blockface Segments are unbroken sections of the curb. A blockface can be made up of several subblocks, or just one subblock. There are blockfaces on both sides of the road, each dependent on an unbroken length of curb. For more information please visit DDOT's wiki page

The dataset contains locations and attributes of blocks, created as part of the Master Address Repository (MAR) for the Office of the Chief Technology Officer (OCTO) and participating DC government agencies. The blocks used street centerlines information from DDOT. Blocks include named alleys in DC (such as 'WALTER ALLEY NE'). A block represents a street segment which usually has two bordering streets. The coordinates for the blocks are located at the midpoint of the street segment. More information on the MAR can be found at https://opendata.dc.gov/pages/addressing-in-dc. The data dictionary is available: https://opendata.dc.gov/documents/2a4b3d59aade43188b6d18e3811f4fd3/explore. In the MAR 2, the BlocksPt is called BLOCKS_PT and is primarily based off of street data from DC Department of Transportation's Roads & Highways database, it also features additional useful information such as created date, last edited date, begin date, and more.

Parking meter assets are used to manage and encourage turnover of curbside use on streets in Washington, DC. These assets are owned, operated, and maintained by the District Department of Transportation (DDOT), unless otherwise noted (e.g. meters on National Park Service property are maintained and owned by the National Park Service).

The dataset contains locations and attributes of owner lines with dimensions. The tax information (attribution) comes from the Office of Tax and Revenue's Public Extract file. The creation of this layer is automated, occurs weekly, and uses the most currently available tax information. The date of the extract can be found in the EXTRACTDAT field in this layer.

The dataset contains locations and attributes of building construction and alteration permits applied for and approved by the District of Columbia Department of Buildings. These data are shared via an automated process where addresses are batch matched (geocoded) to the District's Master Address Repository. Users may find that some data points will contain 0,0 for X,Y coordinates resulting in inconsistent spatial locations. Addresses for these data points could not be automatically geocoded and will need to be manually geocoded to 'best fit' locations in DC.
