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: 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.

Description: Imported into SDE on 12/12/18 - from the following layer in the 'General Plan / Environmental Justice' database: OrdAnalysisProximity_06_parcels_A1_A2_INT_DIS. Below is the original metadata for that layer (#6 below).These iterative layers are part of a proximity analysis as requested by the General Plan section to assist with writing the Green Zones ordinance and determining where zone changes should go (HelpDesk ticket #805650). The following Industrial Zones were considered and intersected with parcels: C-M, M-1, M-1.5, M-2, M-2.5, MPD. Then a 'near' analysis was done within a 1,000' search radius against various sensitive uses. This layer was then used in ArcGIS Pro to publish a hosted layer to be used in a web mapping application for visualization.Selected parcels for industrial zonesIntesected layer 1 with selected zoning categories....deleted sliversDissolved layer 2 on selected fields and exported to SDE for use in the app. THIS IS THE LAYER THAT THE NEAR ANALYSIS WAS DONE ON. After the Near Analysis, the polygons were exported into points - both points and polygon layers are necessary in the app for the zoom levels.Near tables used to join back to layer 3 for the NearDistance fields.Look up tables for residential zoning and specific plan categories used in the sensitive uses map service for the app.Intersection between A-1 and A-2 zoning with parcels - for an additional analysis of residential zoning. Added a field that flags which parcels have residential uses that are notvacant.Selected out 'occupied residential uses' from layer 6 and dissolved on Z_CATEGORY. This was exported into the sensitive uses map service, and also used in the additional near analysis request.

Description: This is a layer of Libraries that is intended to follow the outline of the building outline with a 10 foot buffer to smoothe out the edges. It originally came from the analysis done by DRP in 2010 for Jessica's Law, and LMS was used to join the spatial attributes to it. It has a field called 'GIS_LAYER_SOURCE' indicating the data source and date generated.Next StepsUpdate History:2/8/17 - Combined Building Outlines and LMS data and applied 10 foot buffer to building outline.

Description: This is a layer of Parks that is intended to follow the outline of the parcel upon which it resides. This layer came from the Department of Parks and Rec 'Parks Needs Assessment' for TYPE = "Local Park". This type distinguishes developed parks from the large regional parks or natural areas, as a sensitive use is focused on parks with playgrounds and other amenities where children would be present. Additional work was done to add polygons from our 2010-2012 Jessica's Law analysis to capture additional parks and sports complexes not covered by the Parks Needs Assessment (with the exception of Golf Courses). A 'SOURCE' field was added to distinguish these two sources. Below is a brief description of the Jessica's Law methodology:Jessica's Law methodology: The basis for the 2011 parks data layer began with the State of California’s Protected Areas Database (CPAD) in conjunction with the Southern California Association of Governments (SCAG) existing land use layers from 2005 and 2008. These data layers were cross checked against one another for spatial accuracy and verified with ortho and oblique aerial imagery, and street level imagery. Last update: January 2011.

Map Company, Google Maps, Los Angeles County Department of Regional Planning, Los Angeles County Parks and RecreationUpdate History:2/7/17 - Extracted layer from Parks Needs Assessment.6/19/17 - Added additional polygons from Jessica's Law analysis, did QC on theseNext Steps2/8/17 - Compare with Jessica's Law layer - some parks in this layer cover undeveloped park area.

Description: This is a layer of K - 12 Schools that is intended to follow the outline of the parcel upon which the it resides. It is a combination of a point layer that was geocoded from the Department of Education (DOE) from February, 2017, and the selected parcel from which it intersected. The DOE updates their public schools list weekly, and the private schools once a year. Original downloads can be found in 'OUTSIDE_ENTITIES\Other_Agencies\CA_Dept_of_Education. The eGIS Land Types layer was merged with it as the 'point-to-parcel' selection didn't get every parcel within the school. Additionally, the layer from the Jessica's Law analysis was used to get any schools that were missed. Below is a description of the Jessica's Law methodology:Jessica's Law Analysis: The primary data source for this 2011 layer came from the 2008 Jessica’s Law project performed for the Board of Supervisors. That project pulled coded information from parcel data and checked it against existing Thomas Bros. data and Los Angeles Region Imagery Acquisition Consortium (LAR-IAC) 4” resolution aerial imagery. A further step was taken with the layer by comparing it with information from the Los Angeles County Enterprise GIS Repository, the Los Angeles Times California School Guide website, and by using ortho and oblique aerial imagery, and street level imagery to verify the accuracy of the data. Last update: January 2011.Below is a description of the fields, as well as the update history and next steps:AIN - Assessor's Parcel IDCDS_Code- for schools from DOE, this is the unique identifier for each school. DOE separates the two lists between public and private, so this field can be used in both lists (ie. for future updates or quality checking.FullAddress- this is the address that came from DOE. Any school with a source of "Jessica's Law" or 'eGIS LAND TYPES" will not have this field.SCHOOL_NAME- Name of the school.SOURCE_NOTES- states where this school came from (DOE, Jessica's Law analysis, or eGIS LAND_TYPES).SCHOOL_TYPE - this is the type of school (elementary, HS, etc.). There is not a consistancy with naming within this field as this layer came from multiple sources. This will have to be cleaned up eventually.QC_NOTES - This states whether a school is within unincorporated or within 1,000 feet of unincorporated. For QC purposes, this 'Unin + 1000 foot buffer' area was focused on due to time constraints for using this layer for the Cannabis Ordinance.Update History:2/7/17 - Combined Land Types and geocoded 'point-to-parcel' layers.6/27/17 - added Jessica's law polygons and QC'd areas within unincorporated + 1,000 feet. Should also get latest schools at some point.Next Steps2/8/17 - Additional comparisons need to be made with the Jessica's Law layer and the '...SCHOOLS_ADDITIONAL_FROM_ASSESSOR' layer to try and find newly constructed schools. The latest point layer from DOE should also be used to fill in the attributes for those additional polygons. DONE 6/27/176/27/17 - need to clean up data still. Some polygons need to be merged - especially the Jessica's Law and DOE polys. School Type field needs consistant naming.
