Document Description
The project includes flood mitigation improvements to a stretch of Arroyo Las Positas which has a reduced channel capacity and is prone to flooding. The purpose of the project is to restore flow for a stretch of Arroyo Las Positas and improve water quality by increasing the adjacent riparian habitat and reducing sediment input resulting from flood events. Arroyo Las Positas flows from east to west through the center of the project site, which includes portions of the Las Positas Golf Course and an undeveloped parcel to the east. Project elements would include expanding the channel flood bank; installing flood walls, flood berms, flood gates, and culverts; raising one golf cart path bridge; and relocating golf course features such as trees and golf cart paths. Construction work would require the removal of 116 riparian trees, which would be replaced at a 3:1 ratio.
