East Cypress Emergency Evacuation Information

In the event of a partial or full evacuation* of the East Cypress Corridor Area and surrounding unincorporated areas of the County, all outbound traffic (leaving Bethel Island/Summer Lake Community) is to use a land dam/levee to travel to Holland Tract Road and Delta Road and then use Delta Road to make your way to the Knightsen/Oakley area. Please use this route with caution.

Step-by-Step Evacuation Route Directions

To access the land dam follow the following route:

  • Go to the intersection of East Cypress Road and Sandmound Boulevard
  • Travel South on Sandmound Boulevard
  • Go to the end of Sandmound Boulevard and access a small levee road just to the east of Sandmound Boulevard
  • Travel South on this levee road a short distance until you reach the land dam that traverses over Sandmound Slough
  • Follow the land dam road a short distance until you get to Holland Tract Road
  • Make a right turn onto Delta Road, Delta Road will take you to Brentwood, Knightsen and Oakley

This route is only designated for passenger cars. Commercial vehicles, multi-axle vehicles, RVs, and trailers are not to be used to go over the land dam. A visual of the evacuation route is below. Additionally, a printable handout is available for download below. We recommend you keep a copy in your car and your emergency “go bag.” (Visit www.ready.gov/kit for ore information on what else to include in your “go bag”.)

East Cypress Road Work

The City continues to work with developers on a long-term, complex project to widen East Cypress Road. In the interim, the City formally secured this evacuation route for residents in the event of any emergency through Memorandums of Understanding with private property owners and the Reclamation District’s (RD 799 and RD 2025).

Public safety continues to be a top priority for the City and we are working hard to offer a long-term, permanent solution to this issue.

*The City is the lead on determining whether an emergency requires evacuation.

How do I sign up for Emergency Alerts?

In an emergency situation, the Oakley Police Department or the Contra Costa Office of the Sheriff may need to provide members of the community with up-to-date information and instructions.

Residents and businesses are encouraged to sign up for both programs:

Nixle is an alerting program that allows the Oakley Police Department to contact residents through text and email messages. All you need to do is text our zip code “94561” to 888777 on your cell phone. You can also register through their website www.nixle.com.

The Community Warning System (CWS), run by the Contra Costa Office of the Sheriff, can alert residents and businesses within Contra Costa County that are impacted by, or are in danger of being impacted by, an emergency. The CWS message will include basic information about the incident and what specific protective actions (shelter in place, lockdown, evacuate, avoid the area, etc.) are necessary to protect life and health.
