This alley feature class represents current street centerline lines in the City of Los Angeles. The Mapping and Land Records Division of the Bureau of Engineering, Department of Public Works provides the most current geographic information of the public right of way. The right of way information is available on NavigateLA, a website hosted by the Bureau of Engineering, Department of Public Works. Alley Centerline layer was created in geographical information systems (GIS) software to display alley centerlines. The purpose of the layer is to show the location of the alleys on map products and web mapping applications. The Bureau of Street Services tracks the location of existing alleys that they maintain. Alleys are not dedicated streets, and the use of the road is determined by the Planning Department. Street features in the Street Centerline layer are dedicated. In the Alley Centerline layer, there is no naming convention stored in the corresponding records to identify the names of the alleys. Department of Transportation, LADOT, is working on a naming standard. Note there are Alleys features in the Street Centerline layer are Named Alleys. Since the line features for named alleys are stored in the Street Centerline layer, there are no line features for named alleys in those areas that are geographically coincident in the Alley layer. For a named alley line feature in the Street Centerline layer, the corresponding record contains the street designation field value of ST_DESIG = 20, and there is a name for the alley stored in the STNAME and STSFX fields. Currently the Alley line features in Alley layer do not split the street centerline layer features where they intersect, so there is no intersection point created or maintained in the Intersection layer.List of Fields:ZIP_R: Zip code right.ID: A unique numeric identifier of the line feature. This unique identifier is no longer used and ASSETID is used now instead.AL_DESIG: This value is currently not being used.MAPSHEET: The alpha-numeric mapsheet number, which refers to a valid B-map or A-map number on the Cadastral tract index map. Values:     • ___B___, ___A___, ___-5A___ - Any of these alpha-numeric combinations are used, whereas the underlined spaces are the numbers.SHAPE: Feature geometry.USER_ID: The name of the user carrying out the edits.CRTN_DT: Creation date of the polygon feature.LST_MODF_DT: Last modification date of the feature.ZIP_L: Zip code left.STNUM: Street identification number. This field is currently not being used.OBJECTID: Internal feature number.LINE_ID: This value is currently not being edited. This used to be an automatically assigned unique ID of the alley centerline line segments.ASSETID: User-defined feature autonumber.AL_ID: This value is the ID of the alley as assigned by Bureau of Street Services, Department of Public Works. This is unique for each alley, but not unique for each alley line segment. This field has not been updated.SHAPE.LEN
