Environmental

The environmental review process can include up to three phases: identification, evaluation, and mitigation.

  • Identification: Identify potential significant environmental impacts.
  • Evaluation: Evaluate and study identified impacts.
  • Mitigation: If necessary, address impacts through appropriate mitigation measures.

This process is documented in an Environmental Impact Report (EIR). The City Council certified the Portola Center Subsequent Environmental Impact Report on November 5, 2013, signaling the end of the environmental review process.
