    Description

    This line feature layer contains Legal City boundaries within Los Angeles County.

    The principal attribute is BDRY_TYPE which represents the boundary feature types. Use its values below for definition queries and layer symbology for your mapping needs.

    Coast - This value represents the coastline. This data is carefully maintained by DPW staff, based Los Angeles Region Imagery Acquisition Consortium data.

    Land City - This value represents city boundaries on land.

    Land County - This value represents the county boundary on land.

    Pier - One example is the Santa Monica Pier. Man-made features may be regarded as extensions of the coastline.

    Breakwater - Examples include the breakwater barriers that protect the Los Angeles Harbor.

    Water - This value is used to separate features representing internal navigable waters and the ocean. Examples of internal waters are found in the Long Beach Harbor and in Marina del Rey.

    Ocean - This value is used to represent ocean boundaries between cities in addition to the seaward boundaries of coastal cities. Per the Submerged Lands Act, the seaward boundaries of coastal cities and unincorporated county areas are three nautical miles (a nautical mile is 1852 meters) from the coastline.

    Description

    The TIGER/Line shapefiles and related database files (.dbf) are an extract of selected geographic and cartographic information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). The MTDB represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line shapefile is designed to stand alone as an independent data set, or they can be combined to cover the entire nation. The Feature Names Relationship File (FEATNAMES.dbf) contains a record for each feature name and any attributes associated with it. Each feature name can be linked to the corresponding edges that make up that feature in the All Lines Shapefile (EDGES.shp), where applicable to the corresponding address range or ranges in the Address Ranges Relationship File (ADDR.dbf), or to both files. Although this file includes feature names for all linear features, not just road features, the primary purpose of this relationship file is to identify all street names associated with each address range. An edge can have several feature names; an address range located on an edge can be associated with one or any combination of the available feature names (an address range can be linked to multiple feature names). The address range is identified by the address range identifier (ARID) attribute, which can be used to link to the Address Ranges Relationship File (ADDR.dbf). The linear feature is identified by the linear feature identifier (LINEARID) attribute, which can be used to relate the address range back to the name attributes of the feature in the Feature Names Relationship File or to the feature record in the Primary Roads, Primary and Secondary Roads, or All Roads Shapefiles. The edge to which a feature name applies can be determined by linking the feature name record to the All Lines Shapefile (EDGES.shp) using the permanent edge identifier (TLID) attribute. The address range identifier(s) (ARID) for a specific linear feature can be found by using the linear feature identifier (LINEARID) from the Feature Names Relationship File (FEATNAMES.dbf) through the Address Range / Feature Name Relationship File (ADDRFN.dbf).

    Description

    This pipe feature class represents current wastewater information of 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 storm drain system using a geometric network model, to ensure that its storm drains reflect current ground conditions. The conduits and inlets represent the storm drain infrastructure in the City of Los Angeles. Storm drain information is available on NavigateLA, a website hosted by the Bureau of Engineering, Department of Public Works.Associated information about the wastewater Pipe is entered into attributes. Principal attributes include:PIPE_SUBTYPE: pipe subtype is the principal field that describes various types of lines as either Airline, Force Main, Gravity, Siphon, or Special Lateral.For a complete list of attribute values, please refer to (TBA Wastewater data dictionary). Wastewater pipe lines layer was created in geographical information systems (GIS) software to display the location of sewer pipes. The pipe 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 pipe lines are the main sewers constructed within the public right-of-way in the City of Los Angeles. The ends of line segments, of the pipe lines data, are coincident with the wastewater connectivity nodes, cleanout nodes, non-structures, and physical structures points data. Refer to those layers for more information. The wastewater pipe 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. For the historical information of the wastewater pipe lines layer, refer to the metadata nested under the sections Data Quality Information, Lineage, Process Step section. Pipe information should only be added to the Wastewater 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 Bureau of Engineering. 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:STREET: This is the street name and street suffix on which the pipe is located.PIPE_LABEL: This attribute identifies the arc segment between two nodes, which represents the pipe segment. There could be any number of pipes between the same two maintenance holes and at least one. If there is more than one pipe between the same two maintenance holes, then a value other than 'A' is assigned to each pipe, such as the value 'B', 'C', and so on consecutively. Also, when a new pipe is constructed, some old pipes are not removed from the ground and the new pipe is added around the existing pipe. In this case, if the original pipe was assigned an 'A', the new pipe is assigned a 'B'.C_UP_INV: This is the calculated pipe upstream invert elevation value.PIPE_MAT: The value signifies the various materials that define LA City's sewer system. Values: • TCP - Terra Cotta pipe. • CMP - Corrugated metal pipe. • RCP - Reinforced concrete pipe. Used for sewers larger than 42inch, with exceptions. • PCT - Polymer concrete pipe. • CON - Concrete or cement. • DIP - Ductile iron pipe. • ABS - Acrylonitrile butadiene styrene. • STL - Steel. • UNK - Unknown. • ACP - Asbestos cement pipe. • RCL - Reinforced concrete pipe lined. • OTH - Other or unknown. • VCP - Vitrified clay pipe. • TRS - Truss pipe. • CIP - Cast iron pipe. • PVC - Polyvinyl chloride. • BRK - Brick. • RCPL - Lined Reinforced concrete pipe. Used for sewers larger than 42inch, with exceptions. • B/C - Concrete brick pipe. • FRP - Centrifugally cast fiberglass reinforced plastic mortar pipe.DN_INV: This is the downstream invert elevation value.PIPE_WIDTH: This value is the pipe dimension for shapes other than round.C_SLOPE: This is the calculated slope.ENABLED: Internal feature number.DN_STRUCT: This attribute identifies a number at one of two end points of the line segment that represents a sewer pipe. A sewer pipe line has a value for the UP_STRUCT and DN_STRUCT fields. This point is the downstream structure that may be a maintenance hole, pump station, junction, etc. Each of these structures is assigned an identifying number that corresponds to a Sewer Wye data record. The 8 digit value is based on an S-Map index map using a standardized numbering scheme. The S-Map is divided into 16 grids, each numbered sequentially from west to east and north to south. The first three digits represent the S-Map number, the following two digits represent the grid number, and the last three digits represent the structure number within the grid. This field also relates to the (name of table or layer) node attribute table.PIPE_SIZE: This value is the inside pipe diameter in inches.MON_INST: This is the month of the pipe installation.PIPE_ID: The value is a combination of the values in the UP_STRUCT, DN_STRUCT, and PIPE_LABEL fields. This is the 17 digit identifier of each pipe segment and is a key attribute of the pipe line data layer. This field named PIPE_ID relates to the field in the Annotation Pipe feature class and to the field in the Wye line feature class data layers.REMARKS: This attribute contains additional comments regarding the pipe line segment.DN_STA_PLS: This is the tens value of the downstream stationing.EASEMENT: This value denotes whether or not the pipe is within an easement.DN_STA_100: This is the hundreds value of the downstream stationing.PIPE_SHAPE: The value signifies the shape of the pipe cross section. Values: • SE - Semi-Elliptical. • O1 - Semi-Elliptical. • UNK - Unknown. • BM - Burns and McDonald. • S2 - Semi-Elliptical. • EL - Elliptical. • O2 - Semi-Elliptical. • CIR - Circular. • Box - Box (Rectangular).PIPE_STATUS: This attribute contains the pipe status. Values: • U - Unknown. • P - Proposed. • T - Abandoned. • F - As Built. • S - Siphon. • L - Lateral. • A - As Bid. • N - Non-City. • R - Airline.ENG_DIST: LA City Engineering District. The boundaries are displayed in the Engineering Districts index map. Values: • O - Out LA. • V - Valley Engineering District. • W - West LA Engineering District. • H - Harbor Engineering District. • C - Central Engineering District.C_PIPE_LEN: This is the calculated pipe length.OWNER: This value is the agency or municipality that constructed the pipe. Values: • PVT - Private. • CTY - City of LA. • FED - Federal Facilities. • COSA - LA County Sanitation. • OUTLA - Adjoining cities.CRTN_DT: Creation date of the line feature.TRTMNT_LOC: This value is the treatment plant used to treat the pipe wastewater.PCT_ENTRY2: This is the flag determining if the second slope value, in SLOPE2 field, was entered in percent as opposed to a decimal. Values: • Y - The value is expressed as a percent. • N - The value is not expressed as a percent.UP_STA_100: This is the hundreds value of the upstream stationing.DN_MH: The value is the ID of the structure. This point is the structure that may be a maintenance hole, pump station, junction, etc. The field name DN_MH signifies the structure is the point at the downstream end of the pipe line segment. The field DN_MH is a key attribute to relate the pipe lines feature class to the STRUCTURE_ID field in the physical structures feature class.SAN_PIPE_IDUSER_ID: The name of the user carrying out the edits of the pipe data.WYE_MAT: This is the pipe material as shown on the wye card.WYE_DIAM: This is the pipe diameter as shown on the wye card.SLOPE2: This is the second slope value used for pipe segments with a vertical curve.EST_YR_LEV: This value is the year installed level.EST_MATL: This is the flag determining if the pipe material was estimated.LINER_DATE: This value is the year that the pipe was re-lined.LAST_UPDATE: Date of last update of the line feature.SHAPE: Feature geometry.EST_YEAR: This is the flag indicating if the year if installation was estimated.EST_UPINV: This is the flag determining if the pipe upstream elevation value was estimated.WYE_UPDATE: This value indicates whether the wye card was updated.PCT_ENTRY: This is the flag determining if the slope was entered in percent as opposed to a decimal. Values: • N - The value is not expressed as a percent. • Y - The value is expressed as a percent.PROF: This is the profile drawing number.PLAN1: This is the improvement plan drawing number.PLAN2: This is the supplementary improvement plan drawing number.EST_DNINV: This is the flag determining if the pipe downstream elevation value was estimated.UP_STRUCT: This attribute identifies a number at one of two end points of the line segment that represents a sewer pipe. A sewer pipe line has a value for the UP_STRUCT and DN_STRUCT fields. This point is the upstream structure that may be a maintenance hole, pump station, junction, etc. Each of these structures is assigned an identifying number that corresponds to a Sewer Wye data record. The 8 digit value is based on an S-Map index map

    Description

    The TIGER/Line shapefiles and related database files (.dbf) are an extract of selected geographic and cartographic information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). The MTDB represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line shapefile is designed to stand alone as an independent data set, or they can be combined to cover the entire nation. Face refers to the areal (polygon) topological primitives that make up MTDB. A face is bounded by one or more edges; its boundary includes only the edges that separate it from other faces, not any interior edges contained within the area of the face. The Topological Faces Shapefile contains the attributes of each topological primitive face. Each face has a unique topological face identifier (TFID) value. Each face in the shapefile includes the key geographic area codes for all geographic areas for which the Census Bureau tabulates data for both the 2020 Census and the annual estimates and surveys. The geometries of each of these geographic areas can then be built by dissolving the face geometries on the appropriate key geographic area codes in the Topological Faces Shapefile.

Description

This line feature layer contains Legal City boundaries within Los Angeles County.

The principal attribute is BDRY_TYPE which represents the boundary feature types. Use its values below for definition queries and layer symbology for your mapping needs.

Coast - This value represents the coastline. This data is carefully maintained by DPW staff, based Los Angeles Region Imagery Acquisition Consortium data.

Land City - This value represents city boundaries on land.

Land County - This value represents the county boundary on land.

Pier - One example is the Santa Monica Pier. Man-made features may be regarded as extensions of the coastline.

Breakwater - Examples include the breakwater barriers that protect the Los Angeles Harbor.

Water - This value is used to separate features representing internal navigable waters and the ocean. Examples of internal waters are found in the Long Beach Harbor and in Marina del Rey.

Ocean - This value is used to represent ocean boundaries between cities in addition to the seaward boundaries of coastal cities. Per the Submerged Lands Act, the seaward boundaries of coastal cities and unincorporated county areas are three nautical miles (a nautical mile is 1852 meters) from the coastline.
