Construction Complete

Construction and grading at the Cate Bank Stabilization site is finished. All heavy equipment has been removed from the staging area. The California Conservation Corps (CCCs) have been working this week to install erosion control material and start the revegetation efforts at the site. Native seed was racked into the soil before the installation of erosion control fabric in order to help stabilize the soil but also the fabric as plants start to grow up through the fabric. Willow staking was done along the toe of the slope, around and between the root wad structures, as well as into the erosion control fabric. Today 200 native container plants, consisting of blackberry, giant rye, clematis, elderberry,  toyon, and monkey flower to name a few were planted into the erosion control fabric.


CCCs working to install the erosion control material at the downstream end of the project site. Willow poles were laid into the trench at the bottom end of the erosion control fabric. Additional Willow and Sycamore stakes were also placed throughout the toe of the slope.

CCC members planting native container stock throughout the project site. Plants were primarily purchased from Santa Barbara Natives with a few additional plants purchased from Growing Solutions in Goleta. All plants were propagated from local sources. Coastal Restoration Consultants helped design the restoration plan for the project. Over 200 container plants were planted throughout the project area today.

Construction Continues

The major construction out at the Cate Bank Stabilization project is nearly complete. Peter Lapidus Construction has been busy this week, starting at the downstream end of the project site and working his way back up the creek and out of the channel. The upper and lower sections of the project called for a large toe trench to be dug and filled with large rocks. Willow and Sycamore poles were placed in this trench as PLC filled it in with rock and dirt around them. The banks were then laid back to a more gradual slope. In the middle sections of the project four large root wads were installed in the creeks right bank to help deflect the flow away from the right bank and protect it from further erosion. Next week PLC will finish the final grading on the upper section and tie up any loose ends before completely pulling his equipment out of the project site. A CCC crew is scheduled to come in next week and lay erosion control material as well as seed and plant the area.

Looking downstream at the end of the project site, this photo shows the right bank to its new grade as well as the toe trench full of willow stakes.

Looking downstream, this photo shows PLC working to install the 4th and final root wad structure in the middle section of the project site.

Construction has started!

Last week the California Conservation Corps worked to fence out the project area and harvest willows and sycamores from the site before construction began. A large pool was dug by the CCCs and lined with plastic sheeting to provide the willow and sycamore poles with water until we are ready to plant them.  Last week limbing and removal of Avocado trees was also done along the access road to the project site.  This week Peter Lapidus Construction began working on the toe trench on the downstream end of the project site. Peter will make his way up stream filling in the toe trench with large rock and laying back the bank to a more gradual grade. Check back later this week for more photos and updates as construction continues.
