OPPORTUNISTIC SAND RFP: Staff member Jantz provided a brief update on the status of the City's Opportunistic Sand program. The Environmental Impact Statement and Special Use Permit application is currently being processed for a Planning Commission hearing in late July or early August. Staff is anticipating a Negative Declaration determination for this project. Moffatt and Nichols Engineers is currently tasked with completing the final permit application and is projecting that these forms will be submitted to the affected regulatory agencies in the next week. Mr. Jantz has processed an amendment to the original consultant contract with Moffatt & Nichol Engineers to perform sieve analysis at the two disposal sites which was identified as additional requirements from the regulatory agencies. 2. OFFSHORE MONITORING DRAFT SCOPE OF WORK: Staff member Jantz is finalizing the scope of work for Offshore Monitoring and will present the draft at the July 11, 1995 meeting. Mr. Jantz will contact Dr. Sonu regarding performing one more monitoring survey for our records. 3. SHORELINE EROSION COMMITTEE UP-DATE: Member Don Jackson briefed the Committee on the June Shoreline Erosion Committee meeting. The Navy's Homeporting Project was the biggest interest to all concerned. Member Jackson explained that the draft EIS document is out for public review and a public workshop is scheduled for July 7th in the City of Coronado. All public comments will be considered, answered and included in the Final EIS due to be completed in December of this year. Steve Sachs explained that the DEIS left open future opportunities to further define where the deposition of dredged material should occur, either on or off shore. The report also states that no contaminated material will be processed for beach disposal, alternative will be included in the Final EIS. Steve Fine of the Army Corp of Engineers was asked to provide an evaluation of the Navy's Homeporting Project and recommend beneficial uses of the dredged material on the region's coastline. Mr. Fine made the following points: Quantity - The quantity of dredged material that will actually make its way to local beaches is estimated at 6.9M cu. yds. based on a 2' overdredge. Without the extra 2', the project will only generate an estimated 4.7M cu. yds. Also, it would be safe SHORELINE EROSION COMMITTEE MEETING SUMMARY June 9, 1995 Page 2 to assume that an additional 25% may be lost due to shrinkage and material handling. Advice would be to consider a range of quantities as a result of unknown factors. Establish Objectives - The Committee should establish objectives based on the benefits derived for the desired purpose. Due to the limited amount of material, providing smaller amounts at all the proposed disposal sites may not provide the affect anticipated. The coastline may not get the recreational amenities as we first had thought due to loss of material and that material being spread to thin. The benefits will be limited and shortlived. The Shoreline Erosion Committee should consider beneficial uses such as storm protection, bluff protection, recreational uses and beach nourishment. When the priorities are defined, a plan can be developed identifying the requirements to implement the desired project. Nearshore Placement - The deposition of material in the nearshore and allowing wave energies to bring the material to shore is a new technique and can not be quantified. There have been no studies evaluating the quantity of sand which actually reaches the shoreline and how long it will stay. Beneficial Uses - The Corp evaluated three options for beneficial uses: Navy Plan - This option evaluated the benefits of the nearshore deposition at the three identified locations recommended in the Draft EIS, ie. Imperial Beach, Oceanside and Del Mar. SANDAG Plan - This option evaluated the onshore deposition at the 9 proposed locations along the region's coastline. Corp Plan - The Corp has recently completed Reconnaissance Reports for the Cities of Imperial Beach, Oceanside and Carlsbad. These documents have identified the need for storm protection due to extensive damage realized in previous storm events. These reports have also identified federal interest exists in order to allow consideration of federal funding assistance for future beach protection projects. The Corp report concluded that Corp Plan is the best use of the money based on the benefits derived from shore protection. The cost of putting sand on the beach for damage reduction outweighs the potential damage from an unusual storm event. Funding - Based on the different costs associated with all three alternatives, the cost differential which needs to be funded is estimated at $17M. The Shoreline Erosion Committee must work with State and Federal legislators to ensure direction allowing the Corp to proceed through the planning and design phases for the Corp Plan. Once the money is known, the Corp and SANDAG can work on a scope of work to deal with all the issues. As we are all aware, the Corp's National Policy is changing and that in the near future the Corp will no longer fund beach protection projects. These projects will be ranked as having no federal interest. Therefore, funding is critical. The Corp can fund approximately 75% but the local agencies will be required to commit to the rest. SHORELINE EROSION COMMITTEE MEETING SUMMARY June 9, 1995 PageS Staff member Jantz distributed three handouts to the Committee referencing the Navy Homeporting project that were from the Shoreline Erosion Committee June Packet. By a vote of 6-0, the Committee approved a motion to write a letter of comment to the Navy referencing recent studies prepared by Dr. Sonu. These studies indicated that, based on the southerly currents and the impacts of the Oceanside Harbor breakwall, the most optimum location to deposit sand on Oceanside beaches is south of Tyson Street. Dr. Sonu has stated that a natural "eddy" effect occurs and that sand is circulated in the area between Tyson Street and the entrance to the harbor. 4. 1995/96 COMMITTEE CHAIR & VICE CHAIR TERMS: By a 6-0 vote Member David Williams was elected as Chair and Mike Howes as Vice Chair for the 1995/96 term. 5. OLD BUSINESS/NEW BUSINESS; Old Business • Coastal Conservancy - Staff member Jantz will provide additional information about the possibility of applying for Coastal Conservancy funding for parking and beach access at the Encina Beach at the next meeting. New Business Member Williams informed the Committee of an upcoming conference being held at the Scripps Institute of Oceanography in La Jolla on June 30, 1995 regarding Coastal Monitoring programs and techniques. This conference may be a good opportunity to further our program. Member Williams and staff member Jantz will investigate and attend if appropriate. November 15-17 is the Annual American Shore and Beach Preservation Association (ASBPA) Conference in San Diego. The Committee expressed an interest in presenting the City's Opportunistic Sand program during this conference. 6. COMMITTEE REPORTS; None 7.
