The Public Process

County Review Process

The Los Angeles County-led environmental review process began in February 2022.

The County completed a Draft Environmental Impact Report (EIR) for the proposed La Brea Tar Pits Master Plan Project in September 2023. The EIR provides an assessment of the project’s probable environmental effects pursuant to State of California requirements under the California Environmental Quality Act (CEQA).

The Draft EIR is available for download here and is also available at the Museum’s ticket desk.

The public is invited to learn more about the proposed plan and Draft EIR, ask questions, and provide input at a community open house:

  • August 2019 – Held public event at El Rey Theater attended by hundreds of community members where three finalist architecture firms presented their approaches.
  • August – September 2019 – Displayed models, drawings, and renderings for three finalists at La Brea Tar Pits for the public to provide input. Thousands of Angelenos gave feedback via survey.
