OBJECTIVE: Obtain a recommendation of approval from the Board of County
Commissioners of a Work Order for Water Quality Monitoring, Data Collection,
Circulation/Sediment Modeling and a Natural Resource Characterization Study of the
Clam Bay Estuary as outlined in the attached PBS&J proposal on a time and materials,
not to exceed basis.
CONSIDERATIONS: The Clam Bay Advisory Committee, as part of its mission as
outlined in County Ordinance 2008-48, is charged with developing a Master Plan for the
health, management and long term viability of the Clam Bay Estuary. In order to
accomplish this mission, water quality standards, monitoring programs, mixing, flushing,
and circulation data, along with natural resources characterizations, must be performed.
Pursuant to the CCNA, PBS&J responded to RFP 07-4153 in June, 2007 and was
recommended by a staff selection committee along with four other consulting firms to
provide a broad range of coastal engineering services to the County. The Board of
County Commissioners awarded a contract to PBS&J in October, 2007, Earlier this
year, the Board afforded the Purchasing Department discretion to begin soliciting Best
Value Offers from firms already under CCNA fixed term contracts. That practice was
officially implemented on May 1 sl for most work orders exceeding $50,000.
A Best Value Offer was solicited from all firms under the Coastal Zone Management
Consulting Contract. PBS&J and Johnson Engineering responded to the solicitation.
and PBS&J was selected by an independent selection committee utilizing standard
criteria.
ADVISORY COMMITTEE RECOMMENDATIONS: The Water Quality and Flushing
Sub-Committee of the Clam Bay Advisory Committee recommended (4-0) for approval
and complete funding of this proposal. At the Clam Bay Advisory meeting of April 16,
2009 this item was unanimously recommended for approval (7-0). At the Coastal
Advisory Committee meeting of May 14, 2009 this item was unanimously recommended
approval (6-0). At the Tourist Development Council meeting of May 28, 2009 this item
was unanimously recommended for approval (8-0).
FISCAL IMPACT: Funding for this proposal will be provided from the Unincorporated

Clam Bay
Water Quality Monitoring, Data Collection, Circulation/Sediment
Model and Natural Resource Characterization
Background and Purpose
Clam Bay and its adjacent water bodies (Figure 1) are important natural features in
Collier County that appear to have historically experienced degraded water quality
conditions. Over the past few decades, the watershed and shoreline of the Clam Bay
estuary, especially Moorings Bay, have undergone significant urbanization, with the vast
majority of the shoreline now hardened with seawalls. Prior studies in similar lagoon
systems in southwest Florida suggest that increased urbanization brings about increased
freshwater inflows and substantial increases in nonpoint sources of both nitrogen and
phosphorus (i.e., Lemon Bay - Tomasko et aI., 2001).
Recent efforts have been implemented to dredge Clam Pass and increase circulation
within Clam Bay (Clam Bay Restoration and Management Plan, 1998). This dredging
has resulted in improved circulation and viability of the mangroves. While these efforts
have shown some environmental improvements, Collier County is interested in obtaining
a thorough understanding of the circulation of the entire lagoon system and its effects on
the entire estumine ecosystem beyond just mangroves.
Increased point and nonpoint source loads of nitrogen and phosphorus, modifications of
the shoreline, and decreased flushing rates could be associated with water quality
degradation. As such, water quality restoration projects may have to deal with issues of
residence time as much, if not more so, than nutrient delivery.
In response to these concerns, Collier County requested PBS&J prepare a proposal to
conduct a circulation and water quality study to determine the following:
· What is the extent and relative health of the natural resources in Clam Bay and
Moorings Bay?
· What do historical data suggest, in terms of status and trends, about the health of
Clam Bay and Moorings Bay?
. How have circulation patterns and residence time changed over time, and how can
this be improved?
. How do circulation patterns and nutrient delivery interact to create spatial patterns
of water quality in Clam Bay and Moorings Bay, and how these patterns affect the
estuarine flora and fauna?
· How will changes in circulation within Clam Bay and between Clam Bay and
Moorings Bay affect the overall estuary?
· How will changes to the configuration and functioning of Clam Pass influence the
adjacent shoreline morphology, wave fields, flushing rates and residence time of
water within the system?
· Does sediment accumulation within the system likely impact water quality,
shellfish, seagrasses, and other benthic organisms?

April 1, 2600e 6 of 16
This draft scope of work (SOW) and proposed budget has been produced to outline the
approach that PBS&J would take to address these questions.
Scope of Work
PBS&J would conduct the following scope of work under Contract Number 07-4153
"Professional Engineering Services for Coastal Zone Management Project" with Collier
County.
Task 1- Development of a Water Quality Monitoring Program
The City of Naples currently conducts water quality monitoring at four stations in
Moorings Bay, immediately to the south of Clam Bay. Moorings Bay and Clam Bay are
interconnected by culveI1S beneath Seagate Drive. A list of the constituents currently
collected by the City is provided in Table 1. In addition, water quality monitoring in
Clam Bay has been conducted by the Pelican Bay Services Division (PBSD) since 1991,
and was conducted by the Pelican Bay Improvement District prior to that (PBSD 2007).
Based on the Clam Bay Water Quality, Mixing and Runoff Subcommittee meeting held
on March 9, 2009, a list of potential Clam Bay constituents is included in Table 2. In
order to better understand the relationship in water quality between Moorings Bay and
Clam Bay, a water quality monitoring program will be established. PBS&J will work
with Florida Depaltment of Environmental Protection (FDEP) to develop water quality
standards specific to Clam Bay.
PBS&J will provide Collier County with a sampling plan for Clam Bay that will provide
data for compal'ison with Moorings Bay water quality data, and will be in accordance
with FDEP data quality standards. Samples will be sent to the Collier County certified
laboratory facility for testing. This data will be collected and analyzed to allow entry into
the Florida storage and retrieval database (STORET). The sampling plan will specifically
address:
· Location of sampling
· Timing and frequency of sampling
· Recommended sampling constituents
· Equipment calibration and verification requirements
· Field sampling procedures and protocols
· Data format and management procedures
PBS&J will provide quality control to ensure compliance with required sampling
protocol. This review would include PBS&J staff being present during the initial
sampling event. PBS&J will also provide assistance and quality control/review services
for data analysis and reporting as well as delivery of a sampling protocol compliance
report.
PBS&J will provide a review of existing (previously collected) water quality data and
provide a findings report to the County. The report will outline the existing

information, provide a recommendation of its quality and evaluate it for compliance
with the total maximum daily load (TMDL) standards adopted by the State of Florida.
This evaluation will be used to develop a point-of-reference using the existing data and
determine if trends can be identified.
The proposed task includes four components:
. Sampling Plan Development
. Quality Control of Field Sampling Program
. Quality Control of Analysis and Reporting
. Findings Report of Historic Water Quality Data

Task 2 - Sediment and Biological Health Characterization
Turrell Hall & Associates will conduct a general sediment and biological health
characterization effort within the project area. This characterization includes an
investigation of the spatial extent and potential depth-related dependence of organic and
fine sediment layers in Clam Bay. This will be completed to understand the probable
spatial extent of adverse biological conditions associated with nutrient supply and
flushing rates. This information will be used to estimate areas that could benefit from
enhanced circulation, as well as areas that should be monitored closely for possible
adverse side effects of circulation enhancement via bottom resuspension and/or increased
flushing.
We anticipate 30 samples to be taken in the field over a 6 to 8 day period. Sample
locations will be determined by selecting different energy/circulation regimes throughout
the project area, i.e. dead-end channels, shallow vegetated areas, shoal locations,
navigation canals, tidal canals, etc. Samples will be collected by inserting a clear PVC
tube - sediment sampler into the bottom sediments until penetration through any potential
organic-rich layers. Following recovery, the samples will be measured for depth to any
visible RedOx layers (an indicator of oxygen availability). Samples will also be visually
inspected for color, general grain size characteristics, etc. At each site, a diver will
visual1y observe the bottom and record observations on general biological community
structure and health (i.e., presence of bivalve siphons, seagrass and/or macroalgal
abundance, etc.). These data will be used to create an interpretative report on the
predicted occurrence of oxygen-stressed areas of Clam Bay, based on sediment
characteristics and benthic community structure.
Task 3 - Physical Data Collection
Hydr02raphic Survey
This task will consist of completing a bathymetric survey of a portion of the project area.
The bathymetric survey of the project area will include Clam Pass (including the ebb
shoal complex), Upper, Inner, and Outer Clam Bay, Moorings Bay, and Doctor's Pass.
Existing, up-to-date survey data will be used where available, The purpose of the survey
will be to delineate the existing bottom topography in order to create an up-to-date
elevation data set. This data set will be used in the hydrodynamic and sediment transport
modeling. Existing published benchmarks will be utilized. The hOlizontal datum
(coordinates) will be referenced to the North American Datum 1983 (NA083) Florida
State Plane Coordinate System. The vertical datum (elevations) will be referenced to the
North American Vertical Datum of 1988 (NA V088) and will be based on published
horizontal and vertical control points. Drawings will be prepared showing the bottom
elevations and contours. Cross-sections will be created indicating measured water
depths, tide information, and existing bottom grades.
Standard survey quality depth sounding equipment will be used to record water depth
data where possible for the project area. Differential GPS and a high frequency single
beam digital fathometer linked to Hypack data collection software will be utilized. Cross
sections will be taken at a maximum 200 foot interval throughout the survey area (Figure
2).

Currents/Water Levels
Current and water level measurements will be taken within the project area over a period
of 6 to 8 days for use in a planning level circulation analysis. This data can also be used
for the calibration of a potential hydrodynamic numerical model. Currents and water
levels will be measured at five and seven locations within the project area, respectively
(Figure 2). These measurements will be obtained through a field investigation using the
following instruments:
· Tide Gauges (7)
o Placed: (1) Outer Clam Bay, (2) Upper Clam Bay, (3) Inner Clam Bay, (4)
Gulf side Doctor's Pass, (5) Gulf side Clam Pass, (6) north of Seagate
Drive in Outer Clam Bay, (7) south of Seagate Drive in Moorings Bay.
· Aquadopp current meters with water level (5)
o Velocity and water level at five locations throughout domain: (1) Clam
Pass throat, (2) Clam Bay pedestrian bridge, (3) Seagate Drive culvert, (4)
Park Shore Drive bridge, and (5) Harbour Drive bridge
Key issues to be addressed using the results include:
· Velocities and flow rates through Clam Pass
· Flow exchange volume and direction between Clam Bay and Venetian Bay
through the Seagate Drive culvert
· Water level differences and tidal phase lag between Clam Pass, Clam Bay,
Venetian Bay, Moorings Bay, and Doctor's Pass
Graphics will be prepared showing the above parameters during the time of deployment.
TI1is information may be used to gain a working understanding of the circulation patterns
in the Clam Bay and adjacent water bodies as well as develop alternatives for enhancing
restoration efforts within Clam Bay through a numerical modeling effort (as described
below).

Task 4a - Development of a Circulation Model for Clam Bay Estuary
In order to examine detailed circulation patterns within the Clam Bay Estuary, a
numerical hydrodynamic model will be developed. The model will be utilized to provide
the baseline conditions of the system with regards to circulation and residence time, assist
in predicting the performance of proposed circulation enhancement activities, and
provide the basis for the sediment transport model in Task 4b.
In support of the proposed hydrodynamic modeling effort, field data previously collected
will be utilized. These data include a bathymetric survey, water level time series at seven
locations, and water velocity time series at five locations. These data will be used to
create an elevation grid, provide boundary conditions, and calibrate the model. The
model domain will encompass the region from Upper Clam Bay to Doctor's Pass.
PBS&J will evaluate multiple conditions for this effort:
a. Existing conditions
b. Modified conditions, including, but not limited to, optimIzation of the
Clam Pass inlet cross-section to optimize tidal flushing, and modified
culvert/opening/bottom elevations at Seagate Drive, Park Shore Drive, and
Harbour Drive. Specific scenarios will be developed in conjunction with
Collier County and the Clam Bay Water Quality and Runoff, Maintenance
Dredging and Sand Bypassing Subcommittee.
Model runs for existing conditions will be used to calibrate the model as well as address
questions regarding existing circulation patterns within the project area. During the
calibration phase. a sensitivity analysis will be conducted to demonstrate variability of
the input parameters used for the modeling effort. Comparisons will be made with
previous modeling efforts. Simulations of modified conditions will be utilized to address
questions and issues regarding potential changes to hydrodynamics within the project
area from existing conditions. All runs will simulate operational ("everyday") normal
tidal conditions. This will include variations in a normal tidal signal that would be
experienced annually; no hurricane or other extreme events will be modeled for this
effort. An evaluation of extreme conditions is beyond the scope of this effort.
PBS&J will provide, within the final report, the results of the hydrodynamic modeling
effort. The information will include the following:
o Description of measured currents and water levels taken as part of the
calibration effort.
o Description of the calibration and sensitivity analysis.
o Description and sources of all bathymetric and boundary condition data
utilized in the model.
o Description and image files showing the extent and configuration of all
model meshes.
o Summary of results for all model runs.
o Animation files of model runs (DVD).
o Digital modeling files (DVD or CD).

Task 4b - Sediment Bypassing and Transport Modeling
In order to evaluate any proposed enhancement to the Clam Pass channel, a numerical
sediment transport model will be developed. Based on the modeling effort completed in
Task 4a, PBS&J will develop a numerical modeling scheme that will focus on the
following:
. Analyze changes in the wave field, current patterns, sediment transpOlt pathways
and rates, and morphology (erosion/sedimentation).
. Evaluate the existing longshore transport and changes to longshore transport due
to proposed modifications to the Clam Pass channel.
. Evaluate different channel configurations to assess channel stability, flushing, and
adjacent shoreline effects. Specific scenarios will be developed in conjunction
with Collier County and the Clam Bay Water Quality and Runoff, Maintenance
Dredging and Sand Bypassing Subcommittee.
Model runs for existing conditions will be used to calibrate the model. During the
calibration phase, a sensitivity analysis will be conducted to demonstrate variability of
the input parameters used for the modeling effort. Simulations of modified conditions
will be utilized to address questions and issues regarding potential changes within the
project area. All runs will simulate operational ("everyday") normal tidal conditions.
This will include variations in a normal tidal signal that would be experienced annually;
no hurricane or other extreme events will be modeled for this effort. An evaluation of
extreme conditions is beyond the scope of this effort.
PBS&J will provide, within the final report, the results of the modeling effort. The
information will include the following:
o Description of measured CUlTents and water levels taken as pmt of the
calibration effOlt.
o Description of the calibration and sensitivity analysis.
o Description and sources of all bathymetric and boundary condition data
utilized in the model.
o Description and image files showing the extent and configuration of all
model meshes.
o Summary of results for all model runs.
o Animation files of model runs (DVD).
o Digital modeling files (DVD or CD).
Data Analysis, Final Report and Coordination
Based on information derived from the numerical modeling effort, PBS&J will develop
recommendations that will outline strategies to manage the system to maximize the
overall benefit. The usefulness of these circulation and sediment models is the ability to
explore options to increase flushing within Clam Bay as well as between Clam Bay and
adjacent water bodies, thus reducing residence time, and provide a prediction of the effect
on submerged aquatic vegetation, water quality, mangroves, and benthic communities.
The recommendations will also consider the costs and timelines of each option; PBS&J
will use available resources to present options that are locally relevant to the issues of
Clam Bay.
