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: PRC 4201 - 4204 and Govt. Code 51175-89 direct the California Department of Forestry and Fire Protection (CAL FIRE) to map areas of significant fire hazards based on fuels, terrain, weather, and other relevant factors. These zones, referred to as Fire Hazard Severity Zones (FHSZ), define the application of various mitigation strategies to reduce risk associated with wildland fires. CAL FIRE is remapping Fire Hazard Severity Zones (FHSZ) for State Responsibility Areas (SRA) and Very High Fire Hazard Severity Zones (VHFHSZ) recommendations in Local Responsibility Areas (LRA) to provide updated map zones, based on new data, science, and technology. This specific dataset provides FHSZs within SRA lands only, and represents the proposed zones, subject to changes based on local hearings. A subsequent dataset release will provide the actual adopted zones. Maps of the proposed zones in SRA are available at: http://frap.cdf.ca.gov/projects/hazard/fhz.html More information about the project can be found at: http://frap.cdf.ca.gov/projects/hazard/hazard.htmlUPDATED - 3/5/15 by taking out any reference to Responsibility Area - that now is in a seperate, more updated layer. Per. Alfie Blanch, this layer should not have any reference to Federal, State, or Local Responsibility Areas. Also, internal slivers were filled in by doing a 'Gap topology analysis.'

Name: Rural Preservation Areas (Antelope Valley Plan)
Display Field: Town_Name
Type: Feature Layer
Geometry Type: esriGeometryPolygon
Description: The Area Plan’s Vision Statement sets the tone of this Element, which is intended to create opportunities for the Antelope Valley to change and grow while preserving the rural lifestyle enjoyed by current residents and support a vibrant economy. The Area Plan’s Rural reservation Strategy guides the Land Use Policy Map, creating a pattern of rural town center areas, rural town areas, rural preserve areas, and economic opportunity areas. Each town in the Valley will flow outward from vibrant town centers that offer a range of housing and local-serving activities for day-to-day living. Lower-density rural residences will surround these town centers, buffered by large contiguous open spaces that contain habitat areas, recreational spaces, and rural economic activities. In addition, the Rural Preservation Strategy and the Land Use Policy Map lay out the framework for how the Antelope Valley will deal with the changes that result from, and take advantage of the opportunities brought on by, new state and regional infrastructure projects, particularly the High Desert Corridor and the Northwest 138 Corridor Improvement Project.For more detailed information about the description and criteria of each Rural Preservation area, please read Chapter 2 of the Antelope Valley Area Plan (click here).ADDED TO SDE 6/17/15UPDATE HISTORY:11/22/16 - updated for massive city boundary update per DPW data. Also corrected overlapping, duplicated polygons in the northern section where the aqueduct / Quail Lake is.

Description: This layer represents the 'Hazard, Environmental and Resource Constraints Map' as depicted in the appendix Figure C.1 in the General Plan 2035. The Constraints were compiled by overlaying many different layers that each had a score attached to them. Class 1 being the least severe, and Class 3 being most severe. In the overlay analysis the maximumnumber for overlapping polygons is the one shown (so even if there are 3 Class 1 polygons and 1 Class 3 polygon in a specific area, that area will get a 3). For more information about how these constraints are classified, please consult Appendix C in the General Plan appendix section (click here).

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.

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.
