Phase 1 of the tributary of Cerrito Creek restoration project is completed. We started by repairing the culvert that runs under the road and rebuilding the support with broken concrete pieces from a volunteers patio. Invasive species of blackberries and Algerian ivy have been eradicated from the banks. The banks of the channel have been reinforced against erosion by terracing with redwood branches from the garden and secured into the ground by posts of hand hewn redwood & stone pine. Erosion netting has been placed over the soil, and several red twig dogwoods have been planted into the banks; they will eventually hold the soil as the roots spread. Mulch was added as the final layer to prevent run off from eroding the bare surface soil and slow the weed growth.
