Adopt Resolution No. ^/'r' approving an amendment to an existing agreement between the City of Carlsbad and Tekmarine, Incorporated, of Pasadena, California, to provide consultant services for reef site evaluations, design review, and post- construction survey of the proposed offshore artificial reef. UJ oa:a.a. O< ITEM EXPLANATION: In December, 1987, Mayor Pro Tern Kulchin, Beach Erosion Committee Members Mario Monroy and David Copley, and City staff met with representatives of the State of California, Department of Fish and Game, to discuss the possibilities of the State of California, Department of Fish and Game, siting an offshore artificial reef along the Carlsbad coastline. Further discussions with State Fish and Game personnel have indicated the State's increased interest in this project particularly as it relates to the potential long-term benefits to marine habitat and its interrelationship with the future enhancement of Batiquitos Lagoon. State Fish and Game representatives will be present at this Council meeting to make a short presentation explaining the proposed project. Since 1980, the State of California, Department of Fish and Game, has been involved with the construction of eight (8) experimental reefs along the Southern California shoreline: San Onofre: completed in 1980 with 10,000 tons of quarry rock funded by the Southern California Edison Company. - Ventura County: completed in 1984 with 7,200 tons of quarry rock with substantial kelp enhancement funded by the State. - Marina del Rey: completed in 1985 with 11,000 tons of quarry rock funded by the State. San Diego off Mission Bay: completed in 1987 with 10,000 tons of quarry rock funded by the State. - Santa Monica Bay off Pacific Palisades: completed in 1987 with 20,000 tons of quarry rock funded by the State. O Oo Page Two of Agenda Bill No. Oceanside: completed in 1987 with 10,000 tons of quarry rock funded by the State. - Topanga Canyon off Pacific Palisades: completed in 1987 with 10,000 tons of quarry rock with substantial kelp enhancement funded by the State. Santa Barbara: construction planned for early 1988 with 10,000 tons of quarry rock to be funded by the State. This State program, designed to study the effects of artificial reefs on renewing fish populations in near-shore waters, began in 1984-85 following passage of special State legislation which enabled State Fish and Game to utilize Federal tax revenues on the purchase of fishing equipment and fuel used for sportfishing. Following siting studies and bottom profiling, construction of the reef is undertaken by means of placing on the ocean floor large boulders produced from a Santa Catalina Island quarry in varying patterns, heights and depths. Using sonar to take depth soundings, the large rocks are spread in the desired configurations. Fish and Game personnel have indicated that the ecosystem begins almost immediately in the form of algae followed by barnacles and small invertebrates. In time, kelp takes root on the reef. A fully effective, self-sustaining ecosystem serving as a productive breeding habitat takes anywhere from five (5) to ten (10) years according to Fish and Game experts. The prospects of an offshore artificial reef near the opening of the Batiquitos Lagoon offers the possibility of increased marine habitat within the lagoon since the Batiquitos Lagoon Enhancement Project, scheduled to begin in 1990-91, will include an open, tidal mouth. Fish and Game personnel have indicated the combination of an offshore artificial reef coupled with a newly enhanced and open lagoon provides the opportunity for extended studies of unique coastal and marine processes. Following the State Fish and Game presentation of this program, staff recommends adoption of the attached Resolution supporting the State's continued investigation of siting an offshore artificial reef along the Carlsbad coastline. FISCAL IMPACT: All costs associated with the reef's design, construction, administration, permit acquisition and related miscellaneous project costs will be the responsibility of the State of California, Department of Fish and Game. Fish and Game personnel estimate the total cost of constructing an offshore artificial reef in Carlsbad to be approximately $300,000. Page Three of Agenda Bill No. State Fish and Game has requested the City assist in providing consultant services for initial reef siting, design review, and post-construction surveying. On August 18, 1987, the City Council adopted Resolution No. 9025 approving a consultant agreement with Tekmarine, Incorporated, of Pasadena, California, for Carlsbad's sand survey and beach profile data gathering program. Accordingly, staff has secured a scope of work and fee proposal from the City's beach erosion/coastal consultants to represent the City's interests in the offshore artificial reef project and provide the necessary coastal engineering services required by the State. The attached amendment to the City's existing agreement with Tekmarine incorporates the necessary coastal engineering services for a negotiated, not-to-exceed fee of $7,721. Funds are available and currently appropriated in the 1987-88 Municipal Projects' Miscellaneous Consultants and Professional Services Account No. 001-820-3130-2479 for this purpose. Staff recommends approval of the attached consultant agreement amendment. EXHIBITS: 1.

TEKMARINE, INCORPORATED CITY OF CARLSBAD Bv City Manager Title APPROVED AS TO FORM: City Attorney EXHIBIT A SCOPE OF WORK FOR CONSULTING SERVICES FOR SITE EVALUATIONS, DESIGN REVIEW, AND POST-CONSTRUCTION SURVEY OF PROPOSED ARTIFICIAL FISHING REEF OFFSHORE OF CARLSBAD SUBMITTED TO: CITY OF CARLSBAD BY: TEKMARINE, INCORPORATED January 5, 1988 INTRODUCTION The State of California, Department of Fish and Game (CDFG), is planning to construct an artificial fishing reef offshore of the city of Carlsbad. The design and construction costs of the reef will be financed by the State at no cost to the City. the City requires the services of a Consultant, however, to ensure the following: 1. That the site and design of the reef are optimized, based on oceanographic and engineering constraints, to enhance the productivity and longevity of the reef and provide maximum benefit to the City of Carlsbad. 2. That the site and design of the reef will not interfere with natural coastal processes or coastal recreational activities, i.e., sediment transport and surfing. 3. That the reef is constructed in accordance with the design specifications and mapped to facilitate utilization by fisherman. A proposed scope of work to accomplish these goals is described below. SCOPE OF WORK TASK NO. 1 - Site Evaluations The CDFG shall select several (presumably 4-6) alternative sites for the proposed fishing reef based on an evaluation of their biological enhancement potential. It is assumed that none of the sites are in water depth greater than sixty (60) feet. The Consultant shall conduct a literature review and/or field 2 investigation, as necessary, to evaluate and rank the suitability of the alternative sites in terms of the following oceanographic, geotechnical, and geochemical considerations: Oceanographic Circulation and upwelling patterns Turbidity Scour due to wave or current action Sedimentation due to coastal or riverine discharge processes Geotechnical Grain size distribution Soil bearing capacity Soil liquefaction potential Geochemical Sediment contamination from nearby outfalls Results of the site evaluations shall be transmitted by letter to the CDFG and the City of Carlsbad. TASK NO. 2 - Reef Design Review Based on the results of TASK NO. 1, the CDFG shall select a site for the fishing reef and submit a reef design to the Consultant for review. Emphasis of the review shall be upon reef impact, if any, on natural coastal processes and coastal recreational activities, e.g., sediment transport and surfing. Review comments shall be transmitted by letter to the CDFG and the City of Carlsbad. TASK NO. 3 - Post-Construction Survey The Consultant shall conduct a post-construction bathymetric survey of the reef. Horizontal control for the survey shall be relative to four (4) buoys, installed and maintained by the reef construction contractor, at the corners of the reef. Actual 3 geographic coordinates shall be determined based on the contractor's specified location of the reference buoys. Vertical control for the survey shall be referenced to the mean lower low water datum (MLLW). A survey grid shall be established over the reef relative to the four (4) construction buoys. Grid line spacing is to be dependent on the final reef design. An analog trace of the bottom shall be obtained along each grid line with an echo sounder. Additionally, SCUBA divers shall make selective observations and measurements of the reef to substantiate and facilitate the interpretation of the echo sounder record. The final work product of the survey shall be a plan view of the reef and adjacent seafloor indicating depths digitized from the echo sounder records and depths measured by the divers. Contour lines shall be included to highlight shoals or voids in the reef. Survey results shall be transmitted by letter to the CDFG and the City of Carlsbad.
