A project is a proposal (or any part of a proposal) requiring discretionary approval, which may result in physical changes to the environment. The CEQA Guidelines provide a clear definition of a project (Governor’s Office of Planning and Research). Some examples of projects are applications to change adopted plans (i.e. General Plan Amendments), road widening projects, use permit requests, and subdivisions of property. The term "project" refers to the activity that causes the environmental impact.
