Legend Items


The Santa Monica Mountains Local Coastal Program (LCP) is made up of a Land Use Plan (LUP) and a Local Implementation Program (LIP). The zoning is part of the LIP and regulates land use, density, setbacks, parking, lot coverage and building size, thereby providing a means to implement the LUP. The overall objectives of planning and zoning within the Coastal Zone are to protect coastal resources, public health, safety and welfare, to promote compatibility between various land uses and developments and to promote an attractive and well-planned community. Zoning data is for unincorporated areas of Los Angeles County only.

For more complete information, see Local Implementation Program (LIP) that is available on the main Santa Monica Mountains Local Coastal Program website, or stop by the office of the Los Angeles County Department of Regional Planning, Room 1360 of the Hall of Records, 320 W. Temple St., Los Angeles, CA 90012. Phone: (213) 974-6411.

Land Use Policy

Land use policy establishes the general intended uses and intensity of uses permitted within the Santa Monica Mountains Coastal Zone, including the overall maximum density for residential development and maximum intensity for non-residential development.

Parcel Boundary

The parcel outlines for legal land ownership are from the Los Angeles County Assessor Office. They are updated weekly.

The City / Unincorporated Community boundaries do not appear in the SMMLCP-NET layer list menu, though they do show up in the map viewer itself. Below is some useful information about them.

Incorporated City

There are 88 cities in Los Angeles County, each with its own city council. All of the cities, in varying degrees, contract with the County to provide municipal services. The County provides some services for all residents, like public health protection, public social services, property assessment and vital records.

Unincorporated Area

The unincorporated areas include more than 2,600 square miles outside of the 88 cities. Representing two-thirds of the County’s land and one-tenth of its population, the unincorporated areas have been grouped unofficially grouped into 137 non-contiguous areas. Some of these are as small as a few blocks of land surrounded by cities. Others are urban centers with more than 150,000 residents. Still others in the high desert cover hundreds of square miles and are sparsely populated. If it were a city, these unincorporated areas would be the third most populous in the state, after Los Angeles and San Diego.
