Document Description
The Operator proposes to alter the streambed by removing and replacing existing drain facilities. A concrete ditch, asphalt concrete dike, overside drain, and corrugated steel pipe will be replaced. No native vegetation will be removed from the drain. Damaged fencing will be repaired and revegetation will occur at the edge of the freeway shoulder. The project is proposed to begin in April 2007, and will conclude September 2007. All work will be conducted in the channel with no water flow, therefore diversion will not be needed. No work will be performed in or near the Rio Hondo or its banks. There is currently an existing dirt path between the bank of the Rio Hondo and the project site for access. The Caltrans footprint will not encroach upon this dirt path. Equipment needed to complete the project includes an asphalt dike paver, concrete pump truck, 2-axle dump truck, loader with backhoe, and hydraulic excavator. The drain area to be replaced is 0.19 acre or 963.95 linear feet. The size of the new drain (i.e., the maximum width is 8.86 feet and the height is 2 feet) does not exceed that of the existing drain; therefore there will be no additional permanent impacts to the Department's jurisdiction. The drain is currently concrete lined. The repair materials include concrete (220 cubic yards), rock slope protection (12 cubic yards), sandbags (7.4 cubic yards), and corrugated metal pipe (36 feet). The Operator shall not impact more than 0.19 acre of existing concrete-lined channel. The Operator will not create additional impacts. No native riparian habitat shall be impacted as a result of the proposed project impacts by removing weeds and exotic species within the native habitat in the project vicinity along Rio Hondo Channel for a total of 0.38 acre at a ratio of 2:1 compensation.
