Land Use and Zoning California 4 Minutes Read · published March 08, 2026 Flag of California

San Pedro, California lies within the City of Los Angeles jurisdiction, so floodplain, wetland, historic and tree removal work typically follows city and federal rules as well as coastal or county requirements where applicable. This guide summarizes the common permit paths, which departments enforce rules in San Pedro, and practical steps to apply, appeal, or report a suspected violation. Use the official department pages linked where specific forms and local procedures are maintained; local projects may also need state or federal approvals for wetlands or floodplain work. Read the steps below before you begin excavation, tree removal, or alterations to designated historic resources.

Which permits apply

Permits depend on the activity and location within San Pedro. Typical permits include:

  • Street tree removal or street tree trimming permits for trees in the public right-of-way; see the city tree program for application details[1].
  • Historic review or Certificate of Appropriateness for work affecting designated historic properties or landmarks; contact the Office of Historic Resources for review criteria[2].
  • Building permits for grading or structures that may affect floodplains, issued by Los Angeles Department of Building and Safety (LADBS).
  • Public works or encroachment permits for work in the public right-of-way, managed by Street Services or Bureau of Engineering.
Many projects require more than one permit from different agencies.

Site assessment: wetlands & floodplain checks

Before applying, confirm whether the site is in a mapped floodplain or contains jurisdictional wetland features. Flood map searches are often done through FEMA map tools; local departments may require elevation certificates or flood studies for project review. If work is near coastal wetlands, state or federal wetland permits (for example, California Coastal Commission or U.S. Army Corps of Engineers) may also be required in addition to city permits.

Penalties & Enforcement

Enforcement for tree, historic, wetland and floodplain violations in San Pedro is carried out by the relevant City of Los Angeles departments: StreetsLA/Urban Forestry for street trees, the Office of Historic Resources/City Planning for historic resources, LADBS for building and grading violations, and other city or county agencies for encroachments and environmental compliance. Where federal or state wetlands laws apply, those agencies may also enforce sanctions.
