San Diego Unified Port District: Authority and Public Functions

The San Diego Unified Port District is a California special district that governs tidelands and navigable waterways along 34 miles of San Diego Bay shoreline. Established under California's Harbors and Navigation Code, the District exercises authority over maritime commerce, waterfront development, environmental stewardship, and public access across five member cities. Understanding how the District operates — and where its jurisdiction ends — is essential for anyone navigating waterfront land use, maritime business permitting, or bayfront public policy in the San Diego region. This page provides broader context on how the Port District fits into San Diego's regional governance landscape.

Definition and Scope

The San Diego Unified Port District was created by the California Legislature in 1962 through the San Diego Unified Port District Act (California Harbors and Navigation Code §§ 6940–7000). The District is a public agency — not a city department or county division — governed by a Board of Port Commissioners composed of 7 members appointed by the legislative bodies of the five member cities: San Diego, Chula Vista, National City, Coronado, and Imperial Beach.

The District holds title to, and manages, approximately 4,600 acres of state tidelands held in public trust under the California State Lands Commission. That public trust mandate is the foundation of the District's legal identity: tidelands granted by the state must be used for navigation, commerce, fisheries, and public recreation — not private benefit.

The District's scope encompasses:

  1. Maritime and commercial port operations — including the Tenth Avenue Marine Terminal and the National City Marine Terminal, which handle bulk cargo and vehicle imports
  2. San Diego International Airport — the District operated the airport until 1962, but the San Diego County Regional Airport Authority now governs it independently; the Port District has no current role in airport operations
  3. Commercial real estate and leasing — hotels, restaurants, marinas, and retail on tidelands parcels
  4. Environmental programs — water quality monitoring, habitat restoration, and clean air programs within the bay
  5. Public parks and recreational access — including Embarcadero Marina Park, Chula Vista Bayfront, and Coronado Ferry Landing areas

Scope boundary and coverage limitations: The District's jurisdiction applies only to state tidelands and submerged lands within San Diego Bay and does not extend to upland private property, inland waterways outside the bay, or open-ocean areas beyond the bay mouth. Land use decisions on adjacent private parcels are governed by the respective member city's planning department or the San Diego County Board of Supervisors for unincorporated areas. The District does not regulate construction or zoning within incorporated city boundaries — those decisions rest with bodies like the San Diego City Council. The California Coastal Commission retains concurrent permitting jurisdiction over development within the Coastal Zone, which overlaps substantially with Port District tidelands.

How It Works

The Board of Port Commissioners meets publicly and votes on leases, permits, capital projects, and policy. Each of the 7 commissioners serves a four-year term, with San Diego City holding 3 of the 7 seats proportional to its tidelands acreage share. The Board appoints a President/CEO to manage day-to-day District operations.

The District is financially self-sufficient — it receives no property tax revenue. Operating revenue comes from tenant leases, cargo fees, and facility revenues. According to the San Diego Unified Port District's adopted budget documents, the District manages an annual operating budget in the range of $200 million, funding infrastructure maintenance, environmental compliance, and public programs.

Key operating divisions include:

  1. Real Estate — manages over 550 leases and licenses on tidelands property
  2. Maritime Operations — oversees cargo terminals and cruise ship facilities at B Street Pier
  3. Environmental & Land Use — administers environmental permits and the District's certified Local Coastal Program under the California Coastal Act
  4. Engineering — executes capital improvement projects, including seawall maintenance and pier rehabilitation
  5. Public Safety — the Harbor Police Department, a sworn law enforcement agency with jurisdiction over tidelands and bay waters, employs approximately 200 sworn officers

The Harbor Police Department is distinct from the San Diego County Sheriff and San Diego Police Department. Harbor Police enforce state law and District regulations on tidelands and navigable waters; their jurisdiction does not extend to upland city streets.

Common Scenarios

Waterfront restaurant or hotel lease: A business seeking to operate on tidelands submits a lease application to the District's Real Estate Division. The Board reviews it for consistency with the public trust doctrine and the District's Port Master Plan. California Coastal Commission concurrence may also be required if the project triggers Coastal Development Permit thresholds.

Cargo terminal operations: Shipping companies and freight operators coordinate with Maritime Operations for berth assignments, cargo handling agreements, and terminal tariffs. The District publishes a Schedule of Rates, Charges, and Tariffs governing these transactions.

Waterfront park events: Event organizers applying to use Embarcadero or Pepper Park work through the District's permitting process, which includes noise, capacity, and public access conditions tied to the public trust mandate.

Environmental incident on the bay: Water quality violations or spills on tidelands trigger Harbor Police response and may involve coordination with the California State Lands Commission, the U.S. Coast Guard, and the Regional Water Quality Control Board — not the city of San Diego's environmental office.

Decision Boundaries

The Port District versus city planning bodies represent the clearest jurisdictional contrast in bayfront development. The Port District controls tidelands parcels through its certified Port Master Plan, which functions as a Local Coastal Program under the California Coastal Act. A developer proposing a hotel on a tidelands parcel goes through the Port District, not San Diego's Development Services Department. Conversely, a hotel proposed on adjacent private upland property goes through the city — not the Port District.

A second boundary separates the Port District from SANDAG, the regional planning and transportation agency. SANDAG coordinates regional transportation and growth planning across San Diego County; the Port District's planning authority is limited to tidelands. Where a regional transportation project intersects Port tidelands — such as a trolley extension to the waterfront — both agencies must coordinate, but neither supersedes the other on their core jurisdictional turf.

The District also does not govern San Diego's drinking water supply or wastewater systems. Those functions belong to the San Diego Water Authority and the City of San Diego's Public Utilities Department respectively.
