Santa Clarita Valley Sanitation District (SCVSD) has determined through previous studies that under a Capital Storm event, the Valencia Water Reclamation Plant (VWRP) has the potential to be exposed to erosion along approximately 1,000 feet of the middle section of the existing retaining wall and along the VWRP boundary after flooding due to scour. If the wall is undermined by scour or damaged by a significant earthquake event, VWRP facilities may be damaged or destroyed. The proposed project includes a new ground retaining wall structure to fortify the middle section of the wall and protect the VWRP during a flood scour event and design-level earthquake. In addition, the proposed project would include updates to two existing outfall structures. Temporary construction work would occur along the VWRP boundary as well as an existing Significant Ecological Area (SEA) and California Department of Fish and Wildlife easement west of the VWRP. An operations and maintenance area would be cleared around the existing SCVSD outfall easements for continued use during long-term maintenance of the outfall structures.
