Description: California's coastal management program is carried out through a partnership between state and local governments. Each of the 15 counties and 61 cities located in whole or in part within the Coastal Zone is required to prepare a local coastal program (LCP) that specifies land use and zoning for their respective areas. After certification of an LCP, coastal development permit authority is delegated to the appropriate local government except in certain areas, and the Coastal Commission retains appellate authority over certain types of development and development approved by local governments in specified geographic areas. This dataset provides an current cadastral (parcel-based) depiction of the Coastal Commission's geographic appeal jurisdiction boundary pursuant to Public Resources Code (PRC) Section 30603(a), PRC Section 30613, and California Code of Regulations (CCR) Sections 13577 within the Santa Monica Mountains LCP Segment of Los Angeles County.The geographic appeal boundary is a critical element in both the regulatory and planning programs undertaken by the Coastal Commission and depicts areas where coastal development permits approved by local governments may be appealed to the Coastal Commission. The development of the geographic appeal boundary dataset is part of an effort to create updated digital cadastral jurisdiction boundaries. The appeal jurisdiction is defined in PRC Section 30603(a) as including areas between the sea and the first public road paralleling the sea (FPR) or within 300 feet of the inland extent of any beach or of the mean high tide line (MHTL) of the sea where there is no beach, whichever is the greater distance; areas located on tidelands, submerged lands or public trust lands, and areas within 100 feet of any wetland, estuary or stream, or within 300 feet of the top of the seaward face of any coastal bluff. California Code of Regulations Sections 13577(a), (b), (c), (d), (e), (f), (g), (h) and (i) specify further definitions and boundary determination criteria for each of the geographic appeal jurisdiction boundary components.

Description: The community standards districts are established as supplemental districts to provide a means of implementing special development standards contained in adopted neighborhood, community, area, specific and local coastal plans within the unincorporated areas of Los Angeles County, or to provide a means of addressing special problems which are unique to certain geographic areas within the unincorporated areas of Los Angeles County. These are the boundaries for the 'Area Specific Standards' within CSDs. Examples include Union Pacific in East Los Angeles and Lake Avenue in Altadena. UPDATE HISTORY:11/10/2009 - (San Francisquito Canyon CSD).Modified 10/22/12 (SCV / Palmdale annexations)10/22/14 - for an update of the Certified Coastal Boundary from the Coastal Commission - affects North Area and Coastal Zone11/22/16 - updated from massive city boundary update per DPW data.1/11/18 - CSD ordinance adopted on 12/12/17 by ordinance #2017-0055. The West Altadena Sub-Area was removed and the Lake Avenue Sub-Area was modified and re-named.

Description: H3habitat layer for the Santa Monica Mountains Coastal Zone. Features in this layer represent habitat areas not designated by the California Coastal Commission as either H1or H2.Regarding the multi-part feature identified as “Northern border areas added to H3…”, these are classified as H3because they were not initially shown as part of the Coastal Zone when the California Coastal Commission (CCC) approved, and the Los Angeles County Board of Supervisors adopted, the Local Coastal Program (LCP) Biological 3Resources Map. Subsequent to that approval and adoption, but prior to its certification of the LCP, the CCC refined the Coastal Zone boundary, which prompted these areas to be added to the Coastal Zone. Therefore, the H3added areas are shown on the online GIS maps with the understanding that any proposed development on properties overlaid entirely or in part by them would require determination of the correct habitat category(s) on a site specific basis, using the procedure outlined in Los Angeles County Code Section 22.44.1830.Derived from \DRP_ADVANCE_PLANNING\community_studies\layers\Coastal_Zone\SMMLCP.gdb\SMMLCP_H3_Habitat_Detailed.

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.html
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.

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.
