Title
STPUD Angora Creek Sewer Relocation Project
Description
The California Department of Fish and Wildlife (CDFW) has executed Lake and Streambed Alteration Agreement number 1600-2014-0188-R2, pursuant to section 1602 of the Fish and Game Code to the project Applicant, South Tahoe Public Utility District. The project is limited to removal of a decommissioned sewer pipe crossing Angora Creek. The decommissioned pipe has been filled with a concrete slurry and is already encased in a concrete sleeve which will preclude any leaching of effluent into the creek during the removal operation. Removal of the pipe will be accomplished by placement of a flow and sediment/turbidity barrier within Angora Creek parallel to the direction of flow in the creek. The barrier will be used to isolate part of the exposed, decommissioned sewer pipe from flows in the creek. The isolated section of the creek will be dewatered and the pipe will be cut and removed from the creek bed. The flows will gradually be returned to the dewatered section of the creek bed and then the isolation barrier will be moved to the other side of the creek, again running parallel to the direction of flow. The new section of the creek bed will be dewatered and the remaining section of sewer pipe will be removed. Flows will gradually be returned to the dewatered section of the creek and when turbidity levels have decreased to an acceptable level the isolation barriers will be completely removed from the creek. Trees present within the project zone may be trimmed to the minimum amount necessary to facilitate access to the project site by work crews and construction equipment. It is not anticipated that any trees greater than four inches Diameter at Breast Height (DBH) will be removed.
