Document Description
The Operator proposes to alter the streambed to provide stabilization for 4,750 linear ft. of El Toro Road between the Foothill Transportation Corridor and Glenn Ranch unsuitable material, the benching of earth material with buttresses in areas of slope greater than 2:1. The project will require the use of Geogrid, slope anchors, cellular concrete mats, subdrains, walls, and other specially designed construction methods where needed. The slopes will be recompacted with stabilized blanket-fill type as recommended by the soils engineer. Faces of both cut and fill slopes will be prepared and maintained to control erosion. The proposed contours will be blended with existing grades. After construction is complete, the slopes will be enhanced by the replacement, addition, and introduction of vegetation (native grasses and native shrubs and trees where appropriate). Of a total of 30.5 acres of Department jurisdiction associated with the project site, a maximum of 0.8 acre will be impacted. The banks of Aliso Creek are vegetated with southern sycamore riparian woodland, dominated by western sycamore (Platanus racemosa) willows (Salix spp.), mule fat (Baccharis salicifolia), black sage (Salvia mellifera), mugwort (Artemisia douglasiana), laurel sumac (Malosma laurina), coast live oak (Quercus agrifolia), Mexican elderberry (Sambucus mexicana), and non-native giant reed (Arundo donax).
