The project involves a 5-year cleaning and maintenance program for the following culverts and drainage ditches: (1) a 36-inch RCP culvert and a 42-inch RCP culvert on Fern Drive approximately 200 feet east of Campton Road; (2) two 36-inch RCP culverts at the Morgan Place cul-de-sac; (3) a 36-inch CMP culvert on West Avenue at the S Street dip; and (4) drainage ditches along Indianola Road from Indianola Cutoff to Walker Point Road. The project will entail the manual removal of vegetation in and around the above described existing drainage ditches and culverts. Accumulated silt will be removed by vacuum truck, backhoe or excavator staged on roadways adjacent to the project sites. At the three culvert locations, sediment removal will be limited to areas in front of the culverts. Disturbance will be limited to the minimum necessary to accomplish the identified task. Cleaning and maintenance will be conducted in the dry to the extent feasible. If work is unavoidable when water is flowing in the ditches, standard construction BMP's for the protection of water quality, such as installation of a sediment curtains, will be employed.
The project involves the maintenance of existing drainage culverts and ditches, all of which are man-installed facilities. The removal of accumulated silt will allow the facilities to operate as originally designed. Further, the Lead Agency has determined that use of the categorical exemption is not barred by one of the exceptions set forth in Section 15300.2 of the CEQA Guidelines.
