UPDATE ON ERECTING AN OSPREY NESTING PLATFORM NEAR MARKER 36
Tim Hall discussed permits required for an osprey nesting platform and the high cost of
equipment needed for installation. Mr. Dorrill will pursue Collier County approval of an osprey
nesting platform before the PBSD pursues additional work on cost estimates, a preferred
location, and approval by the PBSD Board.
UPDATE ON STATUS OF USACE PERMIT APPLICATION
The USACE has issued a reissuance of public notice for the Clam Pass dredging permit
application which now includes notification of it having a ten year construction window. Public
comment is due by Feb. 4, 2016. Ms. O'Brien and Tim Hall suggested that it is unlikely that a
permit will be issued prior to 2016 turtle nesting season. Marcia Cravens commented on"Notice
of Intent to Proceed for Clam Pass Maintenance Dredging Permit;" a document summarizing her
comments which was added to the record. Ms. O'Brien commented that the PBSD will oversee
all future Clam Pass dredging and will exercise local control.

Tim Hall reported that he has received the November copper readings and will provide
them to the PBSD as soon as possible. He expects to receive the December readings shortly.
UPDATE ON COPPER READINGS AND THE COUNTY LAB
Mr. Bolick reported that the Collier County Pollution Control Lab expects to be
operational sometime in February. His goal is to replace Benchmark with the County Lab to
obtain copper readings beginning in March, which would result in a lower cost for this service.
UPDATE ON ESTIMATED DATE FOR 2015 CLAM BAY, TIDAL ANALYSIS,AND
BATHYMETRIC REPORTS
Tim Hall reported that his goal is to provide the 2015 Clam Bay,tidal analysis, and
bathymetric reports to the PBSD Board members by Wednesday, January 27.
CLAM BAY MONITORING
Mr. Dorrill spoke to Adam Northrup, Collier County Procurement Services, regarding the
PBSD Board's failure to approve Earth Tech's proposal for Clam Bay monitoring. Mr.
Northrup's preference is to reject all of the proposals received and to resolicit proposals with a
more detailed scope. Mr. Dorrill has asked Mr. Northrup to confer with Ms. Joanne Markiewicz,
Procurement Services Director, for direction forward.
MANGROVES IN BAY COLONY
Tim Hall reported that he will conduct a field visit on Saturday, Jan. 23 to examine the
channels in Clam Bay. Mr. Bolick reported that he is waiting for proposals from two vendors for
water management work to clear mangrove channels in Clam Bay located in Bay Colony. Once
proposals are received, the lowest qualified bidder will be contracted to complete this work.
Tim Hall reported that the infrared aerial photo of Clam Bay has been taken. He has
observed huge leaf loss in the mangroves in Bay Colony; he believes that the dying mangroves
are primarily younger vegetation.
COMMITTEE MEMBER BOHDAN HIRNIAK JOINED THE MEETING AT 1:53 PM.
POSSIBILITY OF SIGNAGE IN CLAM PASS
Committee members discussed the City of Naples consideration of installation of
informational signs reading, "You are responsible for your wake—reckless/careless operation
strictly enforced." The City may apply for a permit to install these signs on the current pilings in
Moorings Bay. Committee members will continue to monitor the progress of this issue at the
City of Naples and will discuss this issue again at a future meeting.

RE: TECHNICAL PROPOSAL FOR SECTION A
RFP# 10-5571 ENVIRONMENTAL Et BIOLOGICAL STUDIES
Dear Mr. Curran:
Turrell, Halt & associates, Inc. is pleased to provide you with this proposal for
environmental and biological services pertaining to the Clam Bay ecosystem. There are two
(2) parts to the scope of work for Clam Bay annual services: Biological Monitoring and
Hydrographic Monitoring. Those services are outlined below.
J3io1o2ica! Scope of Work
The purpose of the biological monitoring is to continue the ongoing studies within the
mangrove preserve and surrounding natural communities in order to evaluate restoration
success and overall health of the Clam Bay ecosystem. This will be accomplished through a
variety of activities and an established set of both qualitative and quantitative
observations.The mangrove community is the target of the proposed monitoring efforts and
this response is provided to accommodate those efforts. We also realize that concerns
regarding both seagrass and offshore hard bottom habitat communities have been expressed
in the past and want to assure the County that Turrell, Hall and Associates(THA)is capable
of adding both seagrass and hard bottom monitoring to our scope-of services if it is needed
in the future.
a. Mangroves - Twenty two (22) monitoring plots have been established within the
mangrove forest and have been used to monitor the area's recovery. Eleven (11) of
the monitoring plots were established In the past by Lewis Environmental Services.
Mangrove tree species, (white, red, and black), will be identified and counted, if
present, in each plot. Tree heights will also be measured and recorded. Other
vegetation in the plots, usually Batts maritima or Salicornia virginica, will be
identified and the percentage of ground covered by these plants will be estimated.
Seedlings within the monitoring plots will be counted within 0.50 m2 quadrats.
Densities can then be determined from twelve (12) haphazardly located quadrat
subsamples.
PAM?3 of 107
Agenda Item#6
Page 2 of 5
Page 2 of 5
An additional eleven (11) monitoring plots have been established by Turrell, Halt and
Associates. Monitoring activities within these plots will include identifying all tree
species present within the plot and recording the diameters at breast height (DBH)
for all living trees with a DBH greater than 2.5 cm. Seedlings wilt be identified by
species and numbers and wilt be estimated by count or percent cover (where high
numbers make individual enumeration difficult).
Additional plots may be added to the program to monitor the response of the
mangroves to lightning strikes or other observed disturbances that occur during the
contract period.
Photographs wilt be taken at each plot and any additional observations, including
standing water, wildlife or signs of stress will be noted. Time, tide, and prevailing
weather conditions will also be noted for each survey.
In addition to the fixed monitoring plots, meandering transects will be walker
throughout the system to inspect for stressed areas and to monitor the condition o
the network of flushing cuts that has been established throughout the system.These
• meandering surveys will be conducted at the end of the rainy:season so that any
maintenance work can be scheduled and completed during the dry season.
Additional inspections can be conducted throughout the year as needed to address
resident or county concerns. Observations made during these pedestrian transects
wilt be included in the annual report.
Each year, scale rectified aerial photographs are taken of the Clam Bay System by
Aerial Cartographics of America. The aerials are produced at 200-scale in both color
and infrared versions. These annual photos will be used to estimate recovery and
die-off areas for the annual report.
b. Other Services as Needed -We are aware of occasional resident concerns that arise
with respect to the vegetated systems within the Clam Bay system. Investigations
and commenting on these concerns will be conducted in conjunction with the
mangrove monitoring.
Hydrog_raphic Monitoring Scope of Work
The purpose of the hydrographic monitoring is to evaluate the tidal exchange in the Clam
Bay system as it pertains to maintaining a healthy ecosystem in the bay and intertidal
wetlands. This wilt be done by comparing the present tidal flushing properties of the system
to previous flushing characteristics, both prior to and after completion of the April 1999
dredging of the inlet and selected portions of the interior bay and inter bay channels.
Pang 4 of 102
Agenda Item#6
Page 3 of 5
Page 3 of 5
Flushing properties of the bay are monitored in two primary ways, though this proposal will
undertake only one of the methods:
a. By evaluating inlet channel geometry to determine if shoal formation has progressed
to where it may impede tidal flushing. This work is currently being conducted
through the Coastal Zone Management Department of the County and is not
included in this proposal.
b. By monitoring the tidal range in the bay in comparison to the tidal range in the Gulf
of Mexico. The tidal range in the bay provides a direct measure of the volume of
water that flows in and out of the bay on a given tidal cycle. This work is included in
this scope. The Pelican Bay Services Division wilt monitor and collect tidal data from
tide monitoring stations already established within the system. Humiston and Moore
Engineers(HEW)will interpret the data and present the results in the annual report.
_The Monitoring Re ort and Presentation Scope of Work
The regulatory agencies that issued the 1998 Clam Pass Restoration permits made the
submittal of an annual report a requirement of the permits. The annual report included an
update of all activities conducted within the system that were part of the restoration
efforts, as well as an update on the status of the habitats within the system. The Pelican
Bay Services Division has determined that continuation of the monitoring and reporting
efforts should continue so that they may maintain a constant and consistent awareness of
the status of the system. All of the activities conducted under this proposed scope will be
compiled into an annual report that wilt be presented in hard copy as well as oral
presentation formats. The data compiled in the report will include summaries of the
biological monitoring, the hydrographic monitoring, and of any other relevant activities
that occurred within the system. THA will coordinate a power-point presentation that can
be given to the residents of the community at one of the PBSD monthly meetings.
In addition to the report for the biological and hydrological monitoring activities, the
proposal team will be available to respond to questions that the PBSD may have related to
environmental issues within the system. Attendance at the monthly PBSD meetings, being
on-call should PBSD, agency, or residents concerns require investigation and responses,and
monitoring and review of other activities that may affect the health or stability of the
system wilt all be provided under the proffered scope of services.

PROPOSED WORK PLAN
Biological Monitoring
The biological monitoring will be conducted according to the methodology stated above.
a. Mangrove monitoring will be conducted in late summer and early fall (August-
October) after the spring and summer growth has occurred.
b. Monitoring of the flushing cuts will be done in October or November after the end of
the rainy season and with enough time to identify areas requiring maintenance and
contract to have the work done during the dry season (March/April).
c. Four (4)water level loggers will be installed within the Clam Bay mangrove areas,
primarily in the northern forested zones where drainage is more likely to cause plant
health issues. Those loggers will be downloaded quarterly and the results compiled
for the annual report.
d. Water quality testing will be conducted by PBSD. Turrell will review the monthly
results of these tests to determine if measured parameters are within expected
limits. This information will be put into graphic form that can be compared to past
testing results.
Once collected all of the data will be compiled and organized for inclusion into the Annual
Report.
In between monitoring and maintenance activities, THA biologists will be available to
respond to questions from PBSD staff. Since we are a local company, field visits and in-
person meetings can be conducted easily and with little delay. This allows us to respond to
PBSD questions and concerns in a timely manner.
Hydrographic Monitoring
As stated in the Scope of Services for the Hydrographic Monitoring Plan, data collection will
be conducted by the PBSD, as has been done in the past, and the data will be provided to
the hydrographic consultant for analysis. HaM will coordinate with PBSD staff on the
deployment of the gages. Additionally, HaM has the capability of assisting the PBSD with
instrument calibration, downloading digital data files from the instrument to computer,
initializing instruments prior to installation, and deploying instruments as needed.

Annual Report
As stated above, all of the information collected throughout the year as part of the
biological and hydrographic monitoring will be compiled, summarized, and organized into
the Annual Report. This compilation will begin in tate October and continue into November.
The report will be completed in late November for submittal to the PBSD.The power point
presentation for the PBSD and Pelican Bay residents will be completed by early to mid-
December for presentation at a subsequent monthly meeting.
Please fee free to contact me if you have any questions regarding this technical proposal.
Sincerely,
Timothy C. Hall

2000
A full year after the dredging work no dramatic changes were apparent. Some mangrove
plots had declined while others appeared in slightly better health. Seedling recruitment
was good throughout. Heavy rains in late 1999 were thought to have contributed to a
dieback in groundcover noted by Lewis Environmental Services. No new mangrove die-
offs or expansion of stressed areas were noted. Work planned fir 2001 included the
experimental Riley encasement method for mangrove propagules.

FROM: Robert L. Goodrick
SUBJECT: Pelican Bay - Environmental Considerations, Permit No. 11-00065-S
Based on vegetation cover and the period of inundation the project
site conforms to the technical and legal definition of a wetland
habitat. This 76 acre proposed fill area is located in an elevated
mangrove forest. The dominant plant species of this community is
black mangrove (Avicennia germinans) . This woody halophyte comprises
approximately 95% of the vegetation cover. In most years the site
will be flooded with several inches of water during the wet season.
Since its inception the Pelican Bay development has aroused considerable
environmental controversy. When this project was examined under the
DRI process most of the regulatory agencies, conservation groups and
concerned citizens were openly critical of the project because of
the apparent potential for adverse environmental impacts. However,
during recent years a substantial data base has been developed through
biological and hydrological studies. The results of these efforts
indicate that the environmental value of the project site is considerably
lower than had been thought originally. The project has received
dredge and fill permits from the Florida Department of Environmental
Regulation and the U.S. Army Corps of Engineers. The other agencies
and conservation organizations have reversed their initial positions
on this controversial development. (See attachments.)
•
Although the project site is technically a wetland habitat, this black
mangrove forest is in a stressed condition. It has been suggested
that the major stress factor is the extremely high ground water
salinities during the winter months. Most of the massive black
mangrove trees are dead or in the process of dying.
The fill site is not a productive area in terms of fish and wildlife
values. Overall secondary productivity and species diversity are
very low. This paucity of individuals and species is probably due
to the wide range in salinity. Few organisms can tolerate such
extremes.

Pelican Bay - Environmental Considerations
January 15, 1982
Page -2-
This mangrove forest does not export significant amounts of detritus
to the adjacent estuarine system. The infrequency of tidal influence
is responsible for this situation.
The following paragraphs appear in the proposed fill permit application
to the U.S. Army Corps of Engineers. They adequately summarize the
environmental importance of the proposed fill area,
"The proposed fill operations will not result in unacceptable alteration
of the Clam Pass estuarine system. The mangrove and associated
wetland areas to be filled are an unimportant wildlife habitat;
export negligible quantities of particulate detritus to the adjacent
bay; account for a small percentage of the carbon budget of the
entire system; are not utilized as spawning or nursery areas by
species of recreational or commercial importance; and, perhaps
by accident of location, do not and will not contribute materially
to the maintenance of estuarine water quality.
The proposed fill plan preserves all tidal mangrove and creek and
pond systems which effectively furnish export products to the
estaurine system; serve as important nursery areas; constitute
viable wildlife habitats; and possibly perform a water quality
maintenance function. (It also preserves certain mangrove communities
which do not appear to perform many of these roles. )"
In conclusion, this black mangrove forest presents a perplexing
paradox. It is both a unique habitat and a relatively unproductive .
wetland. On purely aesthetic grounds the area should be preserved
due to its uniqueness. However, based entirely on environmental
significance and fish and wildlife values the proposed fill site
cannot be defended from development.
