Report Draft

The conceptual grading plan has been designed to maximize the extent of floodplain planting areas with a shallow depth to groundwater in order to support the establishment of willow and cottonwood riparian forest revegetation areas. Areas where the depth to groundwater is anticipated to be greater will be targeted for revegetation with mixed riparian forest that contains more drought tolerant species such as coast live oak, buckeye, box elder, and elderberry, and the highest elevation portions of the site may be revegetated with coastal scrub and grassland habitat. The braided distributary channels across the floodplain are primarily designed to convey flood flows. These areas, designated as Maintained Flow Conveyance Areas (MFCAs), will be revegetated to grassland habitat and maintained to prevent the establishment of woody vegetation that may impede flood conveyance. The farm field will be cover cropped until agricultural operations begin and is the only portion of the site that will be not be revegetated to native riparian habitat.
