Streambed Alteration Agreement (1600-2005-0613-R5) Regarding the Joint Outfall "B" Unit 1 Trunk Sewer, Section 2 Protection Project
Document Type
NOE - Notice of Exemption
Document Description
The Operator proposes to alter the streambed and banks of an unnamed tributary to the San Gabriel River by repairing and reconstructing a sewer pipeline by the placement of approximately 500 cubic yards of fill and 3,000 cubic yards of riprap on and around an unearthed sewer line. The pipe was unearthed during flood conditions that occurred in early to mid 2005. The fill and rip rap will be placed on and around the unearthed sewer line to prevent future erosion and rupture of the pipe line. A temporary access ramp will be required for the repair of the sewer and the Rosemead Blvd Bridge. (Note: the Bridge repair is being conducted by Caltrans under a separate agreement, i.e., # 1600-2005-0663-R5). The access ramp is estimated to be 300 ft. in length with a total area of 0.14 acre and requires approximately 1,700 cubic yards of fill material to be brought in. The access ramp is a temporary impact. Permanent impacts are 0.3 acre (160 linear feet). The County Sanitation District No. 2 Los Angeles will construct the access ramp and leave the ramp for the Caltrans construction crew, and Caltrans will have the responsibility for removing the ramp upon completion of their project and return the area to the pre-existing conditions or better (Streambed Alteration Agreement No. 1600-2005-0663-R5). The proposed repair project will stay within the original footprint and at no time will any native vegetation be damaged or destroyed.
