Environmental impacts can be mitigated or avoided at the source of the problem. Examples are: Reduce event traffic impacts by limiting the size of events and not allowing concurrent events to be scheduled over a set limit. Reduce lighting and noise impacts by enforcing a curfew and enforcing limits on the amount of lighting and noise spilling into neighborhoods. Limit truck traffic entering and exiting the property to the gates and times which impact the neighborhoods the least.

Environmental impacts can be mitigated or avoided by including project features which make implement permanent mitigation measures. Examples are adding traffic stacking lanes using property owned by the agency to avoid traffic stacking on city streets and adding a second main entry gate to avoid traffic stacking on city streets, among other measures.

Mitigation measures are funded in part by the agency causing the environmental impact.
