We can all be prepared to lessen the danger and damage of potential flash floods, debris flows and mudslides as we have seen occur in Southern California.
Many of our local, state, federal agencies along with non-profits have been hard at work to protect our watershed and working hard to prevent floods, mudslides, and debris flow here in Santa Rosa and the entire County. As we have all witnessed these preventative steps have helped greatly.
The fires scarred our landscape creating a waxy coating leaving the ground more vulnerable to erosion due to the fact that the burnt upper layers of soil repel water, which accumulates rapidly and flows with a strong intensity lending itself to picking up sediment, boulders, trees and other debris that creates a bigger punch than just mud. These potential hazards will stick around for a few years. With this in mind, along with the preventative steps being taken, residents need to implement erosion-control measures on their property.
A professional can assist you in assessing your property and what needs to be done. Cleaning your property of burnt trees, plants and other matter may not be a good solution because some of this debris may act as protection from wind and water erosion and slows the water runoff. However, clearing debris from nearby streams, storm drains and drainages is necessary to keep these channels clear.
It’s important to hire and/or consult with a licensed civil engineer with erosion and sediment control experience along with design, installation and maintenance experience.
A long-term maintenance plan is needed. One of the main reasons recommended treatment practices fail is the lack of long-term maintenance by the landowner or responsible party.
