6.1D Page 1 REPO.RT To the Honorable Mayor' anGgqt Council From the Ci Ma.nil .er February 23, 2009 SUBJECT Environmental Regulatory Agency Permitting Assistance Services for the Redwood Shores Lagoon Maintenance Dredging Project RECOMMENDA TION Approve, by motion, a professional services agreement with Huffman-Broadway Group, Inc. of San Rafael to provide assistance with the required environmental agency permitting of the Redwood Shores Lagoon Maintenance Dredging Project not to exceed $118,500.00, and authorize the City Manager to increase the contract amount up to 10% if necessary. BACKGROUND The lagoons in Redwood Shores have not been dredged since they were first constructed in the 1960s. Tidal action, over time, deposits sediment from the sloughs throughout the lagoon system. Excessive accumulation of sediment prevents adequate water circulation which compromises both the operation and the health of the lagoon system. Sediment accumulation in the intake channels impedes the flow of water from the sloughs into the lagoon. Build-up around the outlets of storm drainage structures impedes the flow of storm water runoff into the lagoon. Adequate water circulation prevents stagnation and discourages the growth of widgeon weed. Maintenance dredging removes accumulated sediment and other debris to encourage adequate water circulation. Construction of "The Preserve at Redwood Shores" development (currently ongoing in Area H of Redwood Shores) provides an opportunity to reuse dredged material as wetland enhancement fill within the same area. The cost of the proposed dredging project would be significantly higher if the disposal of dredged material required transport by truck or barge. The developer of "The Preserve" has agreed to accept dredged materials as part of the wetlands restoration project. Any dredging project of this kind requires permitting by various state and federal environmental regulatory agencies. Huffman..Broadway Group, Inc. is an experienced consulting services provider in the highly specialized field of environmental regulatory compliance for Bay area wetlands restoration. The Huffman-Broadway Group, Inc. has successfully assisted the developer and the City as a permit consultant in the past and is familiar with the specific conditions of the proposed project. Staff recommends retaining the Huffman-Broadway Group, Inc., to assist with the permitting process of this project because of their unique expertise and past performance. AL TERNA TJVES Council may choose not to approve this agreement and instruct staff to modify scope of work, or seek other qualified service providers. The required environmental regulatory permits would be very difficult and time consuming to secure without the assistance of an experienced consultant.
