Redwood Shores Lagoon Dredging Project Scope of Services - Moffatt & Nichol Since the Redwood Shores Lagoon is not technically part of the "Bay" as defined by BCDC, it presents some unique advantages as well as constraints. Disposal at Alcatraz, even if technically possible, would most likely not be permitted because it would be considered as an external source. The dredging itself will very likely not be subject to a BCDC permit, but if a disposal site within BCDC jurisdiction is utilized, then a BCDC permit will be required. Also, because the lagoon is not considered to be part of the Bay, other resource agencies such as Fish & Wildlife Service and Fish and Game will have a lesser review role. Most Bay dredging projects have significant permit conditions imposed on them - it is likely that this project will be subject only to standard requirements related to water quality and public health. We anticipate that the project will need an Army Corps individual permit under Section 404 of the Clean Water Act and a Water Quality Certification from the SfRWQCB. In addition, if the material is proposed to be disposed at an upland/ marsh location, permits from other agencies may be required. The DMMO permit application serves as a joint application for both agencies, as well as others should they be required. Wetland restoration projects which need fill and already have a permit do not require additional environmental review for each disposal episode, so it is possible that disposal at such locations may not require additional permits for the lagoon project. We will assist the City with preparing the permit applications and prepare necessary graphics for the same. Some form of CEQA and/or NEPA review may be necessary which could be determined after the disposal site is identified. We have not included a scope for preparing environmental documents, because it is pre-mature to do so without identifying a disposal site or defining other project components. Public perception of dredged material as a "waste" is another significant constraint during the public review process for residential areas. In many cases, a public outreach/ awareness program has to be implemented by the local government to educate the community about the need and the impacts of dredging. We will coordinate with the City's public outreach consultant and provide necessary facts and figures for a newsletter or, if necessary, a workshop to educate the public on construction means and methods. Deliverable: DMMO Permit application including project description, graphics, and tables Task 2.2 - Prepare Bid Documents Design of the project and preparation of plans, specifications, and engineer's estimates are relatively straightforward for dredging projects. This project will likely be controlled in large part by the ability to properly anticipate and negotiate the permit conditions without delay or incurring additional expense. In particular, the matter of unauthorized overdepth dredging has become a significant issue in the dredging industry, since the threat of regulatory enforcement has increased the liability of both contractors and owners. Dredgers faced with the increased risk are passing the costs on, or simply refusing to bid on excessively risky work. Several solutions are possible; M&N will work with the City and the regulatory community to develop a practical solution to this problem so that work can be competitively bid. The project approach and schedule places emphasis on this item to better minimize this risk. M&N will prepare design drawings, technical specifications, and estimates of construction cost. The design will consider sequencing of dredging operations to accommodate environmental requirements (fish windows), lagoon operations, and disposal site constraints. Plans, specifications, and cost estimates will be submitted for City review and comment at the 65% 6
