Description: This layer was created on 3/16/16 following the adoption of the Brackett Field Land Use Compatibility Plan by the Airport Land Use Commission (ALUC) on 12/9/15. This layer is meant to contain any additional regulations required by any new ALUC plans. For example, the Brackett Field plan had additional regulations for Critical Airspace Protection Zones, Site-Specific Exceptions, and Compatibility Zones. This is for line layers (such as noise contours). Please consult the ALUC webpage here for more detailed information about these plans.UPDATE HISTORY:3/16/16 - added to SDE following Brackett Field adoption on 12/9/15

Description: Community standards districts are established to provide a means of implementing special development standards contained in adopted neighborhood, community, area, specific, and local coastal plans, or to provide a means of addressing special issues which are unique to certain geographic areas.

Description: This is the outcome of a multi-step process in which parcels were selected and intersected with Land Use Policy and Zoning. Also, taxroll information was appended as well as overlays from several districts and constraints model layers. The parcels used were from February, 2012. In the 'working layers' geodatabase, there are all the iterations of the parcel layer as various analyses were done (file naming has letter prefixes to denote the order of layers created). In the summary folder of this directory, a methodology write-up was begun, but it is incomplete as it was found that some of the processes didn't quite work as they should. TOPOLOGICAL INTEGRITY NEEDS TO BE EMPLOYED to reduce the time spend on this type of analysis. Also, some sort of MODELING PROCEDURES need to be worked on to help streamline this process! The resulting spreadsheet was sent to the General Plan section on 8/9/12, and can be found in the 'support' folder. IMPORTANT NOTE - 'parcel_analysis_2012_unin_taxroll' table links to this layer as it has several Taxroll fields. This seperate table is necessary as it makes this layer more usable for editing (too big of a file size otherwise). UPDATE HISTORY: 12/4/12 for latest recommended changes in the Proposed Antelope Valley plan. 12/5/12 for latest annexations (9/11/12, 11/28/12).1/3/13 - for 'Batch 5' changes for zoning consistancy in Town & Country1/9/13 - for 'Batch 6' changes for zoning consistancy and BRC recommendations in Town & Country1/17/13 - minor Proposed LUP update for General Plan - updated Adopted Density / FAR for all parcels2/26/13 - finalized remaining changes for Town & Country3/18/13 - finished QC of parcels (deleting / merging slivers, adjusting for parcel shifts, comparing LU with public / privately owned parcels) for the AV, GP areas.

Description: This layer represents the Transit Oriented Districts depicted in Figure 6.5 in the General Plan 2035. These are urban and suburban areas with access to major transit and commercial corridors that have the most potential for infill development, and are well-suited for higher density housing and mixed uses. With the exception of the East Los Angeles 3rd Street Specific Plan, and Willowbrook TOD Specific Plan, all of these are 1/2 mile buffers around a major transit stop.

Description: There are 91 Zoned Districts encompassing all of Los Angeles County. These were originally adopted to facilitate zoning in the County. It should be noted that Zoned Districts are not a form of zoning per se. Rather, they simply represent geographic areas associated with established developed areas (i.e., cities, communities, major subdivisions, etc). Today, they are used by DRP as a geographic reference for organizing all historic, recent, and pending zone changes and permits in the unincorporated area. The Zoned District layer is updated whenever annexations and/or de-annexations are adopted. Additional information regarding Zoned Districts can be found in the Los Angeles County Code, Title 22 (previously - Chapter 22.16, Part 1).

Description: This layer features the adopted zoning for all unincorporated areas of Los Angeles County except Santa Catalina and San Clemente islands. Santa Catalina Island is zoned differently from the mainland portion of the County (see below), and San Clemente Island is a U.S. military installation with no zoning. This layer was created as part of the Zoning Map Conversion and Integration Project (ZCIP). For a summary of the zoning categories, please see our Zoning Summary page here: http://planning.lacounty.gov/luz/summary. For complete information, see Title 22 (Planning and Zoning) of the Los Angeles County Code.

Description: Santa Catalina Island falls under a specific plan (22.46.050 et.al.), which designates land use districts for the unincorporated area of the island. These land use districts serve the same role as zones, but supersede the basic zones in Title 22. This has been in effect as of the adoption of the Santa Catalina Island Specific Plan in 1989.
