Document Description
The proposed Project will install a 63-inch diameter high-density polyethylene (HDPE) culvert above two deteriorating existing 36-inch corrugated metal pipes. The new culvert will discharge into an existing three foot high flume that will be filled with rock slope protection (RSP). A larger size of RSP (half ton RSP) will be placed on top of the existing size # 2 RSP, adding additional protection to the outlet. In order to remove the inlet basin groundwater, an 18-inch HDPE under-drain with permeable material at the inlet will be placed into one of the existing 36-inch corrugated metal pipe. This under-drain will outlet at the beginning of the existing flume into the porous RSP #2 backing that will be placed to fill the flume. The other 36-inch corrugated metal pipe will be filled with concrete slurry and abandoned in place. No native riparian trees, shrubs or oak trees greater then 4 inches in diameter at breast height (DBH) shall be removed as a result of planned construction activities for this Project. One California bay between 4 to 12 inches DBH and one sycamore 12 inches DBH will need to be trimmed. Also, seven willows less than 4 inches DBH will be removed. Water diversion around the work area will be required.
