Document Description
In 1978 the City constructed a high flow bypass channel for San Luis Obispo Creek near Los Osos Valley Road. This bypass channel allows larger flows (flows greater than a 10-year event) with an alternate path of travel than the natural stream channel. Since 1978 little maintenance has been performed on the bypass channel and the channel now has large deposits of silt and excess vegetation which do not allow the channel to perform as designed. The project will remove approximately 3,500 cubic yards of sediment and thin existing vegetation. The project area is approximately 400 feet by 70 feet (0.65 acres). The anticipated depth of silt to be removed is 3.5 feet. During the excavation, islands of vegetation will remain and after the excavation is complete the disturbed area will be seed cast in order to expedite vegetation growth. The removed silt will be trucked out of the project area outside of the flood plain. In order to remove the material, the contractor will be allowed to deposit the material on City property (25 Prado Road). The contractor will also be allowed to take the material to other locations as long as the other site is approved by the City Engineer.
