Rainfall that is significant enough to result in runoff can flow into storm drains, channels, creeks, and rivers that empty onto the beaches of Ventura County. In general, 0.2 inches (2 tenths of an inch) of rainfall may be enough to create significant runoff conditions.
There is a potential for storm water runoff to carry disease causing bacteria to the beaches and into the ocean water. In addition, storm water runoff can transport physical hazards such as partially submerged tree limbs and logs into the ocean that could result in serious physical injury. Contact with this runoff water will result in an increased risk to human health and should be avoided for at least 72 hours after all rainfall activity has ended.
