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.

Description: Existing Metro lines came from Metro's GIS download page. Proposed Metro lines were broken into two categories - Planned and Under Construction. The Proposed lines were mapped manually using Project maps from Metro's site, along with LACO_TRNL and Aerial Photos - maps for the individual projects can be found here. Copied from 'Geodatabases' on RPFILE01 to SDE on 9/2/14 (NOTE: formerly, this layer was named 'TRANS_MTA_METRO_RAIL' - MTAwas taken out of this name as that agency no longer uses that acronym).UPDATE HISTORY:3/8/16 - Updated for Gold Line Extension going into effect, updated remaining Gold Line extension to 'Construction', updated Purrple Line 'Planned' to 'Construction', added Regional Connector line.

Description: The Hillside Management areas are identified as areas of having 25% or greater slope, and this layer shows that using the Digital Elevation Model as extracted in 2006 by the LAR-IAC project. The resolution of this dataset is 5 feet for the urban areas, and 20 feet for the National Forest area. For the Castaic CSD and Santa Monica Mountains, the slope is broken down into two categories: 25 - 50% slope, and 50% or greater slope due to those ordinances / plans having those additional requirements.

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.'
Copyright Text: CAL FIRE recoginzes the important contribution of various local government entities that contributed data, maps, and comments that were critical components of the FHSZ mapping process.
