Recommendation to receive report and provide direction to staff on the options addressing biotechnical and various other alternatives for the Ocean Boulevard (Bluff) Erosion and Enhancement Phase 2 Project. (District 3)
DISCUSSION
Background
On April 22, 2014, the City Council asked staff to consider delaying the continued implementation of the Ocean Boulevard (Bluff) Erosion and Enhancement Phase 2 Project (Project).

In response to the City Council's direction, City staff provided the attached May 13, 2014 memorandum (Attachment A).
On July 1, 2014, the City Council considered a geotechnical peer review report (Attachment B) and directed the City Manager to: 1) move forward expeditiously with the top park portion of the Bluff (including the new required irrigation system) and with any of the other infrastructure improvements, such as railing and sidewalk work; 2) evaluate biotechnical alternatives for the remaining portions of the slope that have not received the final shotcrete treatment, as discussed in Section 3.0 of the Peer Review Report and report back to the Council; 3) conduct limited additional shotcrete in transitional areas, comp...
