Second Street Berm Project, northern terminus of Second Street, Berkeley

The City will install a temporary berm/levee along the south side of the high terrace adjacent to Codornices Creek from the eastern side of the terminus of Second Street to an existing high point approximately 255 to the west. The 175' of this structure will be an earthen, while 80' will be standard K-rails placed where space between the riparian corridor and the street is limited. The earthen berm will typically be 1' wide at the top and have 2:1 bank slopes throughout. The maximum elevation of the top of the earthen berm will be 11' (using NGVD datum) to match the general height of the upper terrace on the northern side of the creek. The berm will be constructed of approximately 115 cubic yards of clean soils on top of the existing valley-flat. The berm alignment will typically range from 5-20' from the existing riparian corridor and will allow for the existing footpath to remain usable to pedestrians in the area.
