Rules and Enforcement
RULES AND ENFORCEMENT
It’s important to remember that the Irvine Open Space Preserve is a natural environment, and that naturally-occurring conditions (e.g. weather patterns such as heavy rains or Santa Ana winds, and behavioral changes within animal populations such as rattlesnakes) and anthropogenic conditions (e.g. illegal trails through sensitive habitat areas) may require the City to restrict public access or activities.
During your visit to the Preserve, please pay attention to informational signs and respect barriers such as gates, boulders, and cactus. From time to time you may also encounter City of Irvine staff, Irvine Ranch Conservancy naturalists, and Irvine Open Space Patrol officers…please follow their guidance, as they are present to protect both you and the land. Violation of the rules may earn you a citation.
