This lateral pipes feature class represents current wastewater information connecting a residence or business to the mainline sewer in the City of Los Angeles. The Mapping and Land Records Division of the Bureau of Engineering, Department of Public Works provides the most rigorous geographic information of the sanitary sewer system using a geometric network model, to ensure that its sewers reflect current ground conditions. The sanitary sewer system, pump plants, wyes, maintenance holes, and other structures represent the sewer infrastructure in the City of Los Angeles. Wye and sewer information is available on NavigateLA, a website hosted by the Bureau of Engineering, Department of Public Works.For a complete list of attribute values, please refer to (TBA Wastewater data dictionary). Wastewater Lateral Pipes lines layer was created in geographical information systems (GIS) software to display the location of wastewater lateral pipes. The laterals lines layer is a feature class in the LACityWastewaterData.gdb Geodatabase dataset. The layer consists of spatial data as a line feature class and attribute data for the features. The lines are entered manually based on wastewater sewer maps and BOE standard plans, and information about the lines is entered into attributes. The lateral lines are constructed from LA City's main sewer connection to the Landbase parcels as shown on the Wye maps. The wastewater lateral pipes lines are inherited from a sewer spatial database originally created by the City's Wastewater program. The database was known as SIMMS, Sewer Inventory and Maintenance Management System. Lateral pipe information should only be added to the Wastewater lateral pipes layer if documentation exists, such as a wastewater map approved by the City Engineer. Sewers plans and specifications proposed under private development are reviewed and approved by BOE. The Department of Public Works, Bureau of Engineering's, Brown Book (current as of 2010) outlines standard specifications for public works construction. For more information on sewer materials and structures, look at the Bureau of Engineering Manual, Part F, Sewer Design, F 400 Sewer Materials and Structures section, and a copy can be viewed at http://eng.lacity.org/techdocs/sewer-ma/f400.pdf.List of Fields:REHABRECORDEDLENGTHLATERALTYPE: This value is the type of lateral line. Values:     • Dash - This value is for laterals that were created from a Sewer permit taken out for construction of the lateral.     • Solid - This value is for laterals that were constructed when original pipe lines were constructed.MATERIALENABLED: Internal feature number.SHAPE: Feature geometry.LAST_UPDATE: Date of last update of the line feature.USER_ID: The name of the user carrying out the edits of the pipe data.SPECIAL_STRUCTDIAMETEROBJECTID: Internal feature number.CRTN_DT: Creation date of the line feature.ASSETID: User-defined unique feature number that is automatically generated.ATTACHMENTSHAPE_Length: Length of feature in internal units.
