The Master Plan of Highways was originally developed by the County of Los Angeles Department of Public Works (DPW); it designates roadways in Los Angeles County by their planned capacity. Categories include major highway, secondary highway, limited secondary highway, parkway and expressway. Last updated, 8/15/12 for a Board adopted change in Agua Dulce.

This is zoning for the unincorporated areas of Los Angeles County. This shows zoning how it is shaded on traditional zoning maps (red = commercial, green = open space, etc.)

For more complete information, see Title 22 (Planning and Zoning) of the Los Angeles County Code, or stop by the office of the Los Angeles County Department of Regional Planning, Room 1360 Hall of Records, 320 W. Temple St., Los Angeles, CA 90012. Phone: (213) 974-6411. (Note: Citations which follow refer to sections within the Zoning Ordinance). LAST UPDATED 12/31/14 for zone changes in South Whittier, East Los Angeles, and an annexation in Santa Clarita Valley. PLEASE NOTE, Santa Catalina Island is not included in this dataset. It is in a separate data layer since Catalina has specific zoning categories that differ from the Countywide zoning categories found in Title 22.

This layer delineates ridgelines within selected CSDs whereupon restrictions are established for grading and ridgeline development. Last updated 10/29/14 for updated Significant Ridgelines in newly certified Santa Monica Mountains Coastal Plan. This data is for UNINCORPORATED AREAS only.

This table/chart is a sum of the number of permits, by permit type; for permits in UNINCORPORATED AREAS managed by the Dept. of Regional Planning. Permit type codes are explained in the attached spreadsheet.

This is from the Case Information layer also provided on this site. It shows the extent of past and currently pending permit cases (e.g., CUPs, yard modifications, plot plan reviews, environmental assessments, etc). These cases were drawn from the legacy CTRACK database, and are updated on a monthly basis from the currently active KIVA database. Cases mined from both databases reflect the wide range of land use issues addressed and administered by the LA County Dept of Regional Planning, both past and present. Most cases are parcel-based, although some pertain to subdivisions or other planning boundaries. Note that Notices of Violation (pertaining to Subdivision Map Act Section 66499.36) file numbers are also featured in this layer.

This table (Subdivision Activity) represents land subdivisions in the unincorporated area that are recorded, approved, or pending in the subdivision process. These are Tract Maps (TR) and Parcel Maps (PM).

This layer/table was created to track the more than 600 Business License checks, and nearly 75 DMV referrals, that the LA County Department of Regional Planning's Land Development Coordinating Center (LDCC) processes on an annual basis. As of July 2014, over 20,000 referrals had been processed since the 1970’s. The intent of a referral is to confirm the consistency of a proposed business with a parcel’s zoning.
