' SHORE AND MANGROVE PROTECTION DEMONSTRATION PROJECT
A Navigational Maintenance Project Incorporating Shore and
' Mangrove Re- establishment and Protection, Habitat Improvement,
and Improved Stability.
' Sponsored Jointly by the CHANNEL DREDGING COMMITTEE
ASSOCIATIONS (CDCA) and the AMERICAN WETLANDS RESEARCH
FOUNDATION, INC. (AWRF) and Coordinated with the MARINE
' RESOURCES COUNCIL of EAST FLORIDA, INC. (MRC).
A Proposal for Cooperation with the FLORIDA DEPARTMENT OF
ENVIRONMENTAL PROTECTION, OFFICE of ECOSYSTEM MANAGEMENT,
' ECOSYSTEM PLANNING AND COORDINATION Group, and
A request for matching funds from - Foundations, Government
' Organizations and private Associations and Corporations that
recognize the benefits of Total Resource Management.
' INTRODUCTION
The Project is being undertaken as a demonstration of how long -
range ecosystem management can be implemented while providing
solutions to practical problems that are more commonly dealt with
by addressing symptoms rather than causes. Typical of this
misdirection of effort is the placement of navigation channels in
' locations that require frequent maintenance. The maintenance
itself can be environmentally disturbing and the spoil, even though
it comes from the immediate area, is typically trucked to an upland
site and used for construction fill. By incorporating knowledge of
' ocean processes including waves, currents, tides and winds and
their interactions with soils and vegetation, we can harness the
forces, and the natural reactions to them, to reduce maintenance
' requirements, protect shoreline vegetation, and provide habitat for
important estuarine creatures.
' Planning for this first demonstration project began in 1995 with
careful bathymetric monitoring to track the needs for navigational
channel maintenance, and oceanographic observations related to boat
traffic in the Atlantic Intracoastal Waterway.
' In March 1996 the Channel Dredging Committee Associations executed
a grant to the American Wetlands Research Foundation, ' Inc. to
' provide scientific and technical guidance leading to a long range
plan directed toward overall ecosystem management instead of
opposing the forces of nature just to provide safe navigational
' access for boats. Four condominium associations representing sixty
six berth owners have approved of this approach.

' SHORE AND MANGROVE PROTECTION DEMONSTRATION PROJECT
' The program is being managed by John E. Downey representing CDCA
and Robert M. Snyder, P.E., C.E.P. representing AWRF.
' The Channel Dredging Committee Associations will pay for
construction costs of the program. AWRF is seeking student and
instructor assistance for experimental habitat activities and
monitoring from FAU, FIT, and local school science projects. AWRF
is also seeking matching grants to cover experimental and
monitoring expenses and other costs to insure timely reporting of
progress both to agencies and to the general public.
GOALS AND OBJECTIVES
AWRF believes that individuals, like ecosystems, should be treated
holistically as opposed to being categorized as boaters, fishermen
(sport OR commercial), builders, developers, taxpayers, regulators
or environmentalists. Any individual can, and may, fit into many
categories, and all share in the benefits of intelligent ecosystem
management. Increasing their knowledge, their interest, and their
Participation helps clear the road blocks for collaborative efforts
that lead to efficient, long range progress towards realizing
productive harmony between man and nature.
Our GOAL is to demonstrate the effectiveness of this approach in
such a way that different elements of our work (and combinations
thereof) can be adopted throughout the Indian River Lagoon,
estuarine Florida, and elsewhere, where similar problems exist.
Our results will be related to environmental science and technology
and reported at technical society meetings, to regulatory agencies,
and to the public, in a format that will allow direct application
' of the scientific and technological principles to other locations.
Our OBJECTIVES are to apply the scientific and technological
' principles to a specific site that typifies many locations where
the maintenance of boat traffic and protective boat berthing not
only seem contradictive to each other, but where each independently
can have continuing environmental impact when addressed in the
' narrow confines of single element problem solving. We don't
profess that there are permanent solutions since we share-'a dynamic
environment where maintenance, even in wilderness systems, is a
functional requirement. We do profess, however, that a holistic
approach can not only reduce maintenance, but can lead to overall
long term environmental enhancement.

' SHORE AND MANGROVE PROTECTION DEMONSTRATION PROJECT
' PROJECT DESCRIPTION
The project area is just north of the S.R. 707 Bridge which crosses
the Atlantic Intracoastal Waterway (AIW) in the Village of
Tequesta, Palm Beach County, Florida. Four adjacent condominiums
have frontage on the eastern shore with thirty three berthing piers
perpendicular to their protective bulkhead. Between the berthing
'
area and the AIW the waters are shallow with a mangrove island
located in the northern half. An access channel was dredged and
has been maintained from the approximate . center of the berthing
' area westward, and nearly perpendicular to, the AIW.
South of the S.R. 707 Bridge there is a posted "No Wake" area which
' runs south to the Indiantown Road Bridge. North of the 707 Bridge
there is a channel speed limit which allows high speed traffic.
Because of this, boats in the waters directly waterward of the boat
berthing area at the condominiums are either reducing speed if
1 headed south or increasing speed if heading north. Both of these
speed changes cause the boats to generate increased gravity waves
which then impinge on the shallow waters and through the navigation
' channel. With Florida boat traffic increasing annually, this
activity will continue to increase. The resulting gravity waves
have, over the years, led to the complete loss of a mangrove island
in the south half of the berthing area and have caused significant
erosion and loss of mangroves on the north island. The waves also
disturb and redistribute the bottom sands of the bar system causing
deposition in the navigation channel leading to the boat berthing
' area. This, in turn, leads to an increased requirement for
maintenance dredging.
' In addition, the AIW channel is maintained by the U.S. Army Corps
of Engineers, conducting periodic dredging under contract, with the
spoil placed on the ocean beaches. In this particular area the
' primary source of material is the ocean beaches to the north of the
Jupiter inlet. As beaches are eroded the suspended sediment load
is carried into the inlet where the heavier particles drop to the
bottom of the channel and the fines are deposited as "sling mud" on
' the shallow banks. The fine materials, including ilmenite and blue
clay, result from beach replenishment in the Town of Jupiter Island
where the material is "mined" offshore for placement on the beach.
' During replenishment operations, much of this material moves
quickly southward, into the Jupiter Inlet, and northward through
the AIW. Some of the channel shallowing material comes from the
banks as a result of wave and rain erosion.
The navigation access channel to the boat berthing area is located
such that it tends to intercept the natural migration of shallow
' bottom sand and silt in its attempts to reach a dynamic
Page 3 of 12
1
' SHORE AND MANGROVE PROTECTION DEMONSTRATION PROJECT
' equilibrium. With the loss of the mangrove islands from wave
erosion, there is more unstabilized shallow material available for
' migration into the channel leading to the requirement for more
frequent maintenance work.
' The individuals impacted by the above noted works and processes are
condominium unit owners, boaters, fishermen (sport) , and taxpayers,
As such they are naturally concerned by the escalating cost of
navigational channel maintenance. These individuals are also
' largely professionals and environmentalists. When presented with
the larger picture involving long range environmental management,
they were quick to agree that the benefits were worth the
additional time and expense involved in moving forward with the
SHORE AND MANGROVE PROTECTION DEMONSTRATION PROJECT as proposed by
AWRF. The CHANNEL DREDGING COMMITTEE ASSOCIATIONS was formed and
' the research grant was executed with the AMERICAN WETLANDS RESEARCH
FOUNDATION.
AWRF has reviewed the background information and the oceanographic
' parameters within this project area in relation to the immediate
and long range needs of the project. We have developed a multi-
phase program incorporating the immediate and continuing needs for
' navigational access in such ways as to utilize each step in the
process to move toward long term stability and environmental
enhancement (see Sheets 1 through 4). In Phase I the material from
the next maintenance dredging operation will be used locally to re-
' establish the eroded mangrove island. Wave breaks will be placed
to accumulate additional sand away from the channel to reduce
subsequent maintenance requirements. Phase II will restore and
' protect the vegetated northern island while easing navigational
constraints within the basin. Phase III involves opening a slanted
channel to the south that would be less susceptible to wave caused
' sedimentation. The natural material from the channel would further
expand the eroded mangrove island and protect it from further loss.
The wave barrier installed in Phase I would be moved northward to
add protection to the northern island and the center channel would
' be abandoned. The interior basin would be widened to provide safer
maneuvering. Following each of these Phases, the changes would be
monitored to determine the system response from boat traffic, wind
' waves, and tidal currents.
Depending on the system responses a Phase IV operation could be
undertaken to provide a northern channel cut on an angle to lessen
' wave impact. This material would be used to extend the northern
island that would be protected by a containment dike.
' Page 4 of 12

SHORE AND MANGROVE PROTECTION DEMONSTRATION PROJECT
Previous experience in other projects indicates that intertidal
' vegetated islands can be successfully constructed using adjacent
bottom material and that wave breaks are.effective in reducing or
eliminating wave erosion on mangrove islands. We expect that the
' angled channel(s) will be more stable requiring less maintenance
and therefore less environmental impact. We also are confident
that the re- established islands will provide habitat for a wide
variety of avian and aquatic species.
In applying ecosystem management, it is important to maintain
flexibility in conducting each subsequent phase. Natural
' interactions are highly complex and non- linear and, without
feedback, a program can be forced in a direction contrary to what
is learned in the previous phase(s). Materials, construction
' times, costs, and methods and equipment will be monitored and
reported as part of the basic demonstration project. The results
of the construction work will be applicable to other areas with
similar problems.
PROJECT NEEDS
' In addition to its 1200 miles of coastal shoreline bordering the
Atlantic Ocean and the Gulf of Mexico, Florida has more than 7000
miles of estuarine shoreline. Much of this shoreline is occupied
' by municipal, commercial and residential development that has taken
place over the last 100 to 150 years. Most of this development was
undertaken without knowledge of physical and ecological processes
and how they are influenced by construction activities. The
' conditioning of future development with design criteria based on
modern knowledge does little to correct past problems or current
ongoing maintenance of already permitted activities. By
' incorporating the ecosystem management approach into the
maintenance of existing systems, past development projects can be
upgraded to meet today's criteria.
' The basic engineering designs for the Demonstration Project have
been completed and the regulatory agencies have been advised of the
approach. While the construction and engineering costs will be
borne by the condominium associations, and the ecosystem management
costs are being contributed by AWRF, there are additional
activities that need to be undertaken in order to expand related
ecosystem enhancement activities and to document the project's
successes. These activities include:

conferences; reports to municipal, county, regional, and
' federal agencies; television informational shorts; local
schools and interest groups, and press releases. B -8
' Each of these activities must be planned in coordination with
construction events and Phasing and the overall program must be
organized for efficient execution.
' ORGANIZATIONAL BACKGROUND
The American Wetlands Research Foundation (AWRF) is a 501(c)(3)
' Florida Corporation (IRS #580065863) dedicated to providing and
encouraging innovative solutions to the problems associated with
population growth as they impact ecosystem functions. AWRF was
established in 1980 to incorporate, into land development projects,
' applications of science and technology that contribute to
environmental diversity, productivity and stability. Results have
been widely reported in national and international conferences and
' published in peer reviewed journals. Techniques and methods used
in nearly 100 completed, successful projects have been adopted by
regulatory agencies in permitting policies, guidelines, and rules.
' AWRF maintains a board of professional correspondents around the
world from universities, governmental agencies, corporations, and
Private organizations. To maintain free information exchange these
Page 6 of 12

' SHORE AND MANGROVE PROTECTION DEMONSTRATION PROJECT
' correspondents act as individuals but their professional
associations provide them, and AWRF, with current knowledge of
' important environmental issues and trends. They will accept select
consulting assignments from AWRF to assist in scientific analyses
and evaluations and collaborate on presentation of technical
' papers.
The president and chief scientist of AWRF is Robert M. Snyder who
is a registered Professional Engineer and a Certified Environmental
Professional. Mr. Snyder has been responsible for the planning,
design, permitting, and construction oversight of numerous large
and small scale projects resulting in major long term environmental
' enhancement. In the conduct of these projects he has worked
closely with specialists in chemistry, biology, hydrology,
geophysics, geology, oceanography, and advanced technology. Mr.
' Snyder has also developed a critical path management approach for
strategic planning of complex, long -range ecoregion enhancement
projects.
' BUDGET
In the strategic planning for the type of demonstration project
' described here, it is realized that essentially each element of the
program can, and must, stand on its own as a competent scientific
study. At the same time it is important to realize that each
' element of the program, without appropriate management oversight,
could blossom into a full fledged basic research program of its
own. This program, however, is an applied research /demonstration
project and the field and laboratory work will be limited to that
' which will complement the whole. This is not to say that an
element, or combination of elements, should not serve as a seed for
follow -on work leading to a graduate thesis for example, but that
' the follow -on work would be undertaken under separate auspices.
Without the scientific studies the demonstration project will serve
' its basic functional purpose in providing a broader perspective to
projects that can lead to sustainability and better harmony between
the needs of man and nature. The scientific studies, on-the other
hand, will provide a more competent foundation for extension of
ecosystem management approach on a regional, or even worldwide
basis.
Funding for the basic design and demonstration project has already
been committed. Additional grants are being solicited to cover the
costs of the scientific study elements either singly or
collectively, and for the analysis and presentation of the results.
