Description: This is the outline of LA County to be used for cartographic purposes. There is a "LINE TYPE" field that can be used to symbolize thick lines for the majority of the county outline, then thin lines for the complex areas like Los Angeles / Long Beach Harbor. Updated 1/9/13 to include Los Angeles / Long Beach Harbor area adjustment (DPW linework)
Description: In early November, 2017 we were tasked with analysing how many mobile homes there are throughout the county by unincorporated area, and Supervisorial District. It was also requested to have Assessor data and zoning as well. The eGIS LAND_TYPES layer was used in combination with a downloaded table of addresses from the State of CA Housing and Community Development (website is here). There were significant errors in the LAND_TYPES layer and we used this opportunity to update the polygon boundaries and names using these geocoded points from the state (who ultimately got this info from various fire departments). The layers are listed below, and we informed eGIS of our update efforts so that the LAND_TYPES layer could be updated.DRP HelpDesk Ticket reference #334373Downloaded spreadhseet into support folder, and converted to a File GDB. Used CAMS and Google geocoders, and some manual updates to move points into LAND TYPES polygons. Some are marked as "to remove" since they couldn't be found, or they no longer exist. (Created 11/6/17)Land Types data, queried out from eGIS for Mobile Homes. Layer 1 was used to QC this layer. (Created 11/6/17)Spatial Join between layers 1 & 2. There are some cases where a polygon existed, but no point was represented from the geocoded points (JOIN_FID = -1). The NAME and DESCRIPTIO fields were updated with what was in the joined Geocoded points layer. SOURCE and DATE_UPDATED was also updated. (Created 11/6/17 - updated on 11/9/17 and exported to LAND_TYPES eGIS layer on that day)Clipped Layer 3 for Unincorporated. (Created 11/6/17)

Description: Every ten years, the United States attempts to count every person in the country through a process called the Decennial Census. It is mandated by Article I, Section 2 of the U.S. Constitution. The latest Census was conducted on April 1, 2010, and provides a snapshot of how many people there are and where they live.Once we know how many people there are and where they live in the County of Los Angeles, the population must be divided as evenly as possible into five supervisorial districts for the County of Los Angeles Board of Supervisors. Adjusting the boundaries is called “redistricting.”Per California Election Code Section 21500, et seq., the Los Angeles County Board of Supervisors is required to adjust the boundaries of any or all of the supervisorial districts following each decennial federal census to ensure fair representation. Adjustments to the boundaries are made to ensure that districts are made to be “as nearly equal in population as may be.”Adopted 9/27/11, effective 10/27/11.NOTE: Updated on 1/15/15 to match the layer on eGIS SDE database (with the exception of the LB / San Pedro ports). Original layer DRP had was less accurate as far as lining up with city boundaries - this was exported to 'GEODATABASES/admin_dist' database on 1/14/15.
