Re: SCOPE OF WORK FOR PROFESSIONAL SERVICES RELATED TO THE BEACH
RENOURISHMENT PROJECT AT KEY BISCAYNE, FLORIDA
Dear Mr. Kissinger:
This is to submit a scope of work and fees for engineering services relative to the proposed Key
Biscayne Beach Renourishment project. 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

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.

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.

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.
