Land Development Division
Subdivide Land

Before subdividing land, applicants should consider submitting a “One Stop” application to the Department of Regional Planning. The One Stop consultation will provide a general review of the requested subdivision and advise property owners on issues that will need to be addressed.

Upon deciding to proceed with a subdivision, Tentative Tract and Tentative Parcel Map numbers are assigned via the Internet by the Department of Public Works.

Once an application is submitted to the Department of Regional Planning and fees are paid, copies of the map are forwarded to the Department of Public Works. Public Works will review the application for consistency with the Subdivision Map Act and the Los Angeles County Subdivision Code. Specifically, Public Works will focus on traffic, hydrology, drainage, storm drain, sewer, water, landscaping, road and grading issues. Once approved, final maps and improvement plans will be processing through Land Development for recordation.

Mr. Henry Wong is the Department of Public Works’ representative to the Department of Regional Planning’s Subdivision Committee, where applicants discuss issues with staff. Clearances from the various Public Works divisions and sections are required before the project can be set for public hearing from the Subdivision Committee.

Mr. Steve Burger represents the Department of Public Works at the Regional Planning Commission hearings, which are held every Wednesday morning at the Department of Regional Planning.

Mr. Dennis Hunter represents the Department of Public Works at the Board of Supervisors hearings when projects have a legislative action or decisions of the Regional Planning Commission are appealed.
