Specifically, the following presents a detailed scope of work for professional services to be provided by Coastal Systems International (Coastal Systems) for the initial field investigations, detailed geotechnical investigations, conceptual design, and Pre -Application Consultations required to initiate the project PART I — INITIAL FIELD INVESTIGATIONS a) Bathymetric Survey: An updated bathymetric survey of the borrow area is required to confirm the extent of the area and to meet permitting requirements for the project. The existing bathymetric survey as obtained from Miami -Dade County Department of Environmental Resources Management (DERM) is more than 6 months old and therefore, is not in compliance with code requirements (Chapter 62B-33 F.A C) and policies of the Department of Environmental Protection (DEP). This survey is also required to confirm existing data to avoid potential complications and/or change orders from the dredging contractor during construction. b) Hydrographic Survey: Coastal Systems will conduct a detailed hydrographic survey within the Village of Key Biscayne (Village) The hydrographic survey will be performed at 1,000 feet on center between DEP monuments R-90 and R-113 Additional profile lines will be obtained at 500 feet on center between DEP monuments R101 and R108. The survey will extend from a baseline placed landward of the active beach system to 2,500 feet offshore, or to a depth of 30 feet. This hydrographic survey data will be compared to previous County data in order to analyze the extent of recent erosion This survey will be utilized in the preliminary design of the beach renourishment project and in all phases of the project planning, permitting, and funding Coastal, Environmental, Civil Engineering and Management 135040 Mr C Samuel Kissinger January 6, 1999 Page 2 c) Aerial Photography: Concurrent with the field investigations, Coastal Systems will set horizontal and vertical ground control points required for future aerial mapping. The location and elevation of seven (7) designated control points within the project vicinity will be established. These control points will be sufficiently marked to provide aerial targets for low altitude aerial photography. This photography will be used in the permitting and design phases of the project. Coastal Systems will coordinate with an aerial photography firm to obtain targeted aerial photography of the project area from the DEP Reference Monument R-101 through R- 107, Miami -Dade County. The photography will be centered on the local shoreline. Aerial photographs will be obtained at a scale of 1"=500' on 9"x 9" contact prints. d) Jet Probes: Coastal Systems will perform an initial geotechnical investigation to determine the qualitative content and approximate sediment thickness at locations throughout the borrow area. This analysis will assist in determining the limits of the borrow area and the quantity of available beach quality material. The data will be used to optimize further geotechnical investigations including vibracores and sub -bottom mapping. In addition, this analysis is required to estimate the extent of gravel that could potentially be placed on the beach. This analysis will assist in developing a dredging plan that will be used to obtain the 120,000 cubic yards of material specified for this project. Coastal Systems will obtain approximately thirty-five (35) jet probes within the Borrow Area. e) Resource Mapping: Coastal Systems' marine biologists will assist and coordinate with DERM to assess the extent of any hardbottom and biological resources (seagrass) adjacent to both the proposed fill site and borrow site The map to be provided by the County will provide sufficient information for the regulatory agencies to fully understand the characteristics of the hardbottom or seagrass areas within the limits of the proposed project. f) Base Map: Bathymetric survey data, collected in the field by Coastal Systems, and the hydrographic/control survey data collected by other sub -consultants will be reduced to the Florida state plane coordinate system for representation on the survey plan. The location of core boring data from the U.S. Army Corps of Engineers (COE) will be identified on the base map. Resource map information from DERM will also be placed on the base map. Contours reflecting bottom elevations at 1 -foot intervals within the nearshore (hydrographic survey) and offshore (bathymetric survey) will be illustrated on the survey base map. COASTAL SYSTEMS INTERNATIONAL, INC. • Coastal, Environmental, Civil Engineering and Management 135040 Mr C. Samuel Kissinger January 6, 1999 Page 3 PART II — DETAILED GEOTECHNICAL INVESTIGATIONS a) Sub -Bottom Profiling: Coastal Systems will work in conjunction with a qualified subcontractor to obtain a detailed sub -bottom survey of the borrow area . The survey will be performed using an X -star CHIRP Full Spectrum Digital Sub -Bottom Profiler or equivalent combined with Differential Global Positioning System (DGPS). Sub -bottom profile transects will be obtained every 100 feet in a west to east orientation, and every 200 feet traveling in a north to south orientation. This will result in approximately 50 sub -bottom profile lines that will be used in conjunction with the previous geotechnical investigations to provide the thickness of unconsolidated sediment layers and the location of any significant rock rubble or coral fragments. The sub -bottom profiling system will be calibrated using the available jet probe and vibracore data. A Coastal Systems engineer will oversee the operation to ensure that accurate and reliable results are obtained. This investigation will assist Coastal Systems in accurately delineating the boundaries of usable beach quality fill material and ensure that coral and rubble fragments are not placed on the beach. b) Vibracores within Borrow Area: Vibracores will be obtained within the borrow area to facilitate a detailed understanding of the sub -bottom sediment characteristics Approximately three days of vibracoring will be conducted to achieve a minimum of ten (10) cores at predetermined locations within the borrow area. A geotechnical analysis will be performed on all cores to determine the relevant sediment characteristics including, but not limited to, sediment size distribution (including silt content), mean sediment size, layer thickness, and sediment color The information obtained through this analysis will be used to define the borrow site areas that contain sediment characteristics meeting the Village's sand specifications. PART III — CONCEPTUAL DESIGN a) Compile Data and Review Reports: Coastal Systems will collect and review available data necessary for evaluation of historic and current beach erosion at the project site. Specifically, the data to be collected and reviewed will include, but will not be limited to, hydrographic surveys, aerial photographs, regional reports and studies, sediment characteristics, geotechnical information, sand sources and sea turtle nesting data. Reports prepared by the COE and other studies describing the history and performance of the 1987 beach renourishment project within the project area will be reviewed. Available hydrographic survey data will also be compiled to facilitate volumetric change comparisons along the project shoreline and vicinity. COASTAL SYSTEMS INTERNATIONAL, INC. • Coastal, Environmental, Civil Engineering and Management 135040 Mr C Samuel Kissinger January 6, 1999 Page 4 b) Reevaluate Coastal Processes: Coastal Systems will reevaluate historic shoreline and volumetric changes in combination with an assessment of the wave climate and potential for sand movement. This analysis will facilitate a general understanding of sediment movement and/or stability of the Village's shoreline. c) Environmental Assessment: Coastal Systems will document the environmental characteristics and summarize potential influences of the proposed beach renourishment project on the environment. Site characteristics of the beach and uplands will be presented along with topographic and bathymetric data. The meteorological, oceanographic, and littoral conditions influencing the project shoreline will be summarized. The resources adjacent to the borrow area and along the project shoreline will also be addressed. Conclusions regarding the optimum design for this project will be outlined and recommendations for avoiding and/or minimizing impacts will be presented. d) Conceptual Design: Based on the coastal engineering findings, a conceptual design of beach renourishment along the project shoreline will be determined. The design will identify the extent of the beach renourishment with specific berm height and width and construction slope of beach profile. The quantity of sand required for the beach renourishment project and renourishment frequency will also be identified. e) Report: A report summarizing coastal engineering findings and conceptual design will be provided. This report will also summarize information regarding natural resources within the project area, and address concerns that may be raised by regulatory agencies during permit processing. The report will include a description of the short-term and long-term improvements that are being proposed, the associated design and construction costs, and a schedule for project implementation. This document will be submitted to the regulatory agencies to facilitate permit approvals for the project. PART IV — PRE -APPLICATION CONSULTATIONS Coastal Systems will attend an initial joint meeting with the DEP Bureau of Beaches and Coastal Systems and the COE to present the design details of the proposed construction and identify areas of staff concerns. Coastal Systems will subsequently maintain contact with regulatory staff and prepare for and attend up to two (2) additional meetings with the DEP and COE to finalize the acceptable design details of the proposed construction. Coastal Systems will prepare a conference report for each meeting documenting the discussions and summarizing DEP's and COE's acceptance as to the specific design elements. These reports will serve as DEP's and COE's conceptual approval and will become the basis of the final design. COASTAL SYSTEMS INTERNATIONAL, INC. • Coastal, Environmental, Civil Engineering and Management 135040 Mr. C. Samuel Kissinger January 6, 1999 Page 5 PART V - CLIENT DIRECTED MEETINGS Coastal Systems will attend meetings with the Village as required to present the findings of the field investigations and or conclusions of reports.
