CLAM BAY
UPDATE ON MANGROVE MONIT012ING AND HAND -DUG CHANNEL
MAINTENANCE
Mr. Sterk, Environmental Consultant with Earth Tech, provided exhibits which identified
this year's areas of recommended targeted maintenance of hand -dug channels. This project will
start sometime in June. He also provided a summary of health assessment scores of the 21
monitored mangrove plots. He commented that the overall trend of these plots has been pretty
steady, after the recovery firm Hurricane Irma.
Ms. O'Brien commented that there are four areas of stressed mangroves, as noted in the
2020 Clam Bay Monitoring Annual Report. Mr. Sterk commented that he has established photo
plots of these areas which will continue to be closely monitored and diagnosed. He noted that it
appears that these four areas have no natural or previously established channels, and in the future,
we may need to consider a permit -modification to establish channels in these areas. Ms.
McLaughlin commented that there are a fair number of dead -looking trees at South Beach. Mr.
Sterk confirmed that this area is one of the four areas being closely monitored.
Ms. O'Brien questioned whether standing water has been observed in the mangroves. Mr.
Sterk will look into this during June fieldwork. The committee reviewed selected May Clam Bay
Pelican Bay Services Division Clam Bay Committee Meeting
June 1, 2021
aerials, provided by Humiston & Moore, which showed the conditions of the mangroves in several
areas.
EXOTIC TREATMENT
UPDATED PROPOSAL FOR SCAEVOLA TREATMENT/REMOVAL
Ms. O'Brien commented that a request for quotes for scaevola removal went out last week,
and a copy was included in the agenda packet. Quotes are due back June 10. She noted that at the
last Clam Bay Committee meeting, mechanical removal was discussed and considered the most
efficient and most cost-effective method. However, in the proposal, vendors are asked to choose
their removal method. Ms. O'Brien commented that $75,000 was tentatively included in the
FY2022 budget for this project. Mr. Coleman commented that Fund 111 has at least $35,000
available in this year's budget to fund one phase of this project. He noted that we do not know the
PBF's participation in this project, at this time. Ms. Jacob commented that this RFQ went out to
the five or six exotic vegetation removal vendors on contract with the County.
Mr. Sterk commented that he is not sure how long scaevola has been on the State Prohibited
Exotic List. Mr. Dorrill commented that the PBSD has never done a scaevola removal project
before and he is unaware that this type of project has ever been done by the PBSD in the last 40
years.
TREATMENT IN OTHER AREAS
Ms. O'Brien provided a copy of bid schedule RFQ118-7459, which describes the 2021
tasks of the ongoing exotic removal program by Aquagenix, for a total annual cost of $115,800,
Ms. O'Brien questioned what work is provided under Task 4 (NRPA Exotic Treatment Area —
Quarterly Exotic Maintenance) for $36,000. Mr. Sterk commented that a map of Clam Bay with
corresponding tasks was provided in the agenda packet, which shows about 12 acres on the west
side of the berm, where exotic maintenance work will be completed. Ms. Jacob commented that
she will review past invoices to determine the number of hours that are spent on Task 4 each
quarter. Mr. Sterk commented that Aquagenix provides a daily report of all work completed.
Ms. McLaughlin commented on the exotics, east of the boardwalk, in conservation areas
on associations' property. Mr. Sterk commented that some associations have addressed the exotics
on their property while others have not. Ms. O'Brien suggested creating a PBSD outreach program
on exotic removal for the associations with conservation areas along the east side of the berm. She
suggested that staff develop a strategy for this.
UPDATE ON OSPREY PLATFORMS
Ms. O'Brien commented that two out of our tluee PB osprey platforms are down. Mr.
Sterk has been tasked with replacement/repair of these two platforms, which will be completed
within the next few weeks.
CANOE TRAIL MARKER 8
Mr. Sterk commented that he continues to coordinate with the County's Coastal Zone Mgt.
Division for the repair of canoe trail marker 8.
EXPENSES IN FUND 111
3
Pelican Bay Services Division Clam Bay Committee Meeting
June 1, 2021
Ms. O'Brien provided the FY2022 proposed budget for Fund 111. She highlighted that in
FY2020, we did not spend all of the funds available to us in Fund 111. She noted that this year,
staff is focused on spending the entire $150,000 available to us in our FY2021 budget.
CLAM PASS
TIDAL RATIO RESULTS FOR MAY
Ms. Jacob provided the May Clam Bay tidal ratio results for the committee to review. Dr.
Dabees, Environmental Consultant with Humiston & Moore, commented that ideally we would
like to see the measurements to be above .5 for the four active tidal gauges. He reviewed ratios
from 2017 to the present, along with the related dredging events during that time period. Dr.
Dabees commented that the clogging of Clam Pass is concentrated in the entrance to the Pass,
which is caused by the continuing influx of sand from the recent County beach renourishment
project, just south of Clam Pass.
OPTIONS FOR PASS MAINTENANCE
Dr. Dabees reported that we have sent out an RFQ (to marine services contractors) to obtain
quotes for both a partial excavation and a full dredge. Quotes are due back on June 11. He
suggested that once quotes are reviewed, we can consider these two options in order to make a
recommendation. Although we are in turtle nesting season, currently there are no turtle nests in
the immediate grading area of the Pass. Dr. Dabees noted that we cannot relocate sand, dredged
from the Pass, into any areas containing turtle nests.
Dr. Dabees reported that the County is working on plans for emergency hydraulic dredges
at Wiggins Pass and Doctor's Pass (to be completed after turtle nesting season). He noted that we
have requested that Clam Pass be included in their project. This is a third option available to us.
Mr. Dorrill commented that the Pass does not look alarming in the most recent aerial
photos. He noted that we will closely monitor conditions in Clam Pass, and that we may be able
to delay work until our third option (participation in the County project) becomes available,
subsequent to turtle season.
Mr. Coleman commented on PBF's concerns on the escarpment at South Beach. Dr.
Dabees commented that the flow of water exiting Clam Pass is causing this. Ile noted that (1) the
escarpment can be knocked down, but that it will quickly return at the next high tide, and (2) the
spit must be removed in order to solve the escarpment issue. Mr. Dorrill commented that he would
be able to rent a tr•ackhoe and knock down the escarpment. Dr. Dabees commented that during
turtle season, this would require an approval from FWC. He suggested that it is the responsibility
of the County's turtle nesting monitors to determine if and when to knock down an escarpment.
Ms. O'Brien commented that it is our responsibility to maintain the health of the estuary.
BATHYMETRIC SURVEYS
Ms. O'Brien provided the bathymetric survey results of 5/11/202Q 12/21/2020, and
01/05/2021, which were included in the agenda packet. She expressed concern that Section "C"
was filled with 3,700 cubic yards of sand in January 2021,
MAINTENANCE COSTS IN 2020
Ms. O'Brien provided a summary of 2020 Clam Pass maintenance costs, included in the
agenda packet.

Pelican Bay Services Division Clam Bay Committee Meeting
June 1, 2021
WATER QUALITY
RESULTS FOR JANUARY - MARCH 2O21
Ms. O'Brien commented that we received the January -March 2021 water quality results in
late April.
COPPER RESULTS FOR JANUARY —MARCH 2O21
Ms. O'Brien commented that the latest copper results were added to the table which was
included in the agenda packet. She noted just one problem area (a spike over 6) in these quarterly
results. Copper results, in general, continue to be very good.
DRAFT ARTICLE FOR PB POST
Ms. O'Brien commented that Mr. Rodburg provided an edited draft article entitled "Clam
Bay Water Quality Shows Continued Improvement" for the PB Post, which was added to the
record. Ms. O'Brien suggested and the committee agreed that a photo of Clam Bay and an exhibit
of the eight sampling sites accompany the draft article. The committee discussed minor edits.
UPDATE ON CONSULTANT FOR WATER QUALITY (ADD -ON)
Ms. Jacob reported that the work on Turrell Hall's water quality purchase order has been
completed and that Turrell Hall is no longer on the County's list of contracted environmental
engineering vendors. She commented that our options include (1) hire the next environmental
engineer who is on rotation under the County contract, or (2) hire Earth Tech under the "direct
select" process. Earth Tech would be able to subcontract the water quality reporting work either
to Turrell Hall or ESA (Environmental Science Assoc.) directly. Ms. O'Brien noted that Turrell
Hall has maintained our water quality data for the last 20 years. The committee agreed that the
best option would be for Turrell Hall to continue as our water quality consultant, subcontracted
under Earth Tech's contract.
BEACH NOURISHMENT
TIMELINE FOR DECISION MAKING
Mr. Dorrill commented that the County will receive the deliverables from the engineer's
beach renourishment survey work some time this summer. The exact date is unknown at this time
and will be shared as soon as it is known. Ms. O'Brien commented that this information is critical
so that reviews and recommendations of PB participation can be made in a timely manner. Mr.
Dorrill commented that he expects a November truck haul project.
COST OF ENGINEERING
Ms. Jacob will follow up on the cost of engineering for PBSD's portion of the County's
beach renourishment truck haul project.
BOATER SAFETY SIGNAGE
Mr. Donill commented that at a recent meeting with the County's Coastal Zone
Management Division (CZM), he stressed the importance of the installation of our boater safety
signs. A CZM representative indicated that he expects the installation of these signs to be no later
than year end.

Lisa
The attached exhibits and following notes are provided by Collier County Engineer for the beach nourishment project.
Notes:
2021 comparative profile plots —These plots are relative to the project baseline
"Min Design" represents the 100ft minimum design beach width
"Permitted Template" and "Bid Design" are one in the same in Pelican Bay as these plots were made to match
the current revised design recommendations
Design Table —
Permit capacity as of Jan 2021 is shown by R-mon within the table
Colorful column of 6/22/2021 design needs were based on building the 100ft design beach plus the addition of 6
years of advanced nourishment throughout the project reach.
In the summary table at the bottom by reach, you'll see that the design goal exceeded the capacity of the
permit template, therefore the revised design suggestion was to fill the permitted template (including anticipated
erosion between Jan 2021 and start of construction)

Susan,
You are correct. The previous southern stopping point was 30.8, but we had
agreed with Amy Patterson that the County would use the State and historical 1/2
mile standard which would put the Vanderbilt Beach section down to a little south
of R-32, not R-30.8. Please let me know if there is anything I can do.
Sincerely,

Thanks, Jim.
I know you were very busy today. Would appreciate your confirming that
is the right cut-off between "public" and "private beach. I thought the County had
agreed to extend this cut-off.
Thanks,
Susan

EXECUTIVE SUMMARY
Recommendation to authorize expenditure of Tourist Development Tax funds for Clam Pass
maintenance in the amount of $357,739.80 for Option 2 for construction, engineering and
surveying, monitoring, and permitting, authorize the necessarybudget amendments, and make a
finding that this item promotes tourism.
OBI , .TIVE: To select a marine contractor to per mechanical bypassing and regrading of
accumulated sand and restoration of the Clam Pass inlet channel and banks.
CONSIDERATIONS: Collier County Ordinance No. 2002-27, as amended, established the Pelican Bay
Municipal Service Taxing and Benefit Unit for the propose of providing street lighting, water
management, beach renourishment, ambient noise management, extraordinary law enforcement service
and beautification, including but not limited to beautification of recreation facilities, sidewalk, street and
median areas, identification markers, and maintenance of conservation or preserve areas. Pelican Bay
Services Division (PBSD) is solely responsible for advising the County on dredging and maintaining
Clam Pass and manages such activities for the County.
Clam Pass is a small inlet in Collier County that supports tidal flow to the wetland preserve of Clam Bay
Natural Resource Protection Area (NRPA). Maintenance dredging is essential to the health of the system
because of the relatively small tidal prism for Clam Bay which is typically at a critical balance between
tidal energy and littoral process at the inlet channel. The Florida Department of Environmental Protection
(FDEP) Clam Pass maintenance dredging Permit No 0296087-001-JC was modified in 2019 (Permit No.
0296087-007-JN) to incorporate minor updates to the disposal fill template and conditions for work
during turtle nesting season. Monitoring of the hydraulic and physical conditions of the Clam Bay system
includes continuous water level and tidal data collection at 4 locations within the bay system.
The monitoring of inlet conditions indicates continued high rates of sand accumulation at the south bank
of the inlet and progressive channel migration northward. There has been persistent flow of sand from
south side of the inlet since sand placement at Clam Pass Park in January 2020.
A limited maintenance excavation and grading project was completed in April 2020 to mechanically
bypass the sand accumulation at the south side of the inlet and restore the inlet channel to its design
template. Additional limited maintenance work was completed in December 2020 which included
removal of the sand spit and re -grading the inlet entrance using mechanical equipment. The approximate
volume of sand that was relocated within the template approximately 10,000 cubic yards. These
maintenance events helped restore tidal flow, but the sand has continued to encroach upon the inlet
channel from the south pushing the channel to the north.
The proposed maintenance work includes two options. Option 1 consists of partial excavation and Option
2 consists of full dredging of the template. The conshuction plans show the proposed cut and fill areas.
The approximate volume of sand to be relocated within the template is on the order of approximately
7,000 cubic yards for a partial excavation, and approximately 11,000 cubic yards for a full dredge. Work
is anticipated to start as soon as necessary.
Timeline will be dependent on conditions of the inlet over the coming few months. Clam Pass is a small
dynamic inlet and conditions may change over time especially following storms. The requested quotes are
for two options to allow for inlet maintenance of partial or full dredge of the permitted template
depending on inlet conditions over the coming few months. As such Standard Technical Specs states
Agenda item #6d

inlet maintenance work to be conducted outside of nesting season. However, if conditions of the inlet
require earlier action due to storms during this 2021 tropical season, work may be necessary prior to Nov
1, 2021. The contractor may provide windows of time for their availability for each option over the 6
months period of August 2021 through February 2022 and required lead time from NTP to mobilization.
On May 28, 2021, staff requested quotes from all vendors currently under contract with the County under
Agreement No. 19-7624, "Marine Contractor Services." Two vendors under contract submitted quotes,
which were received and opened by staff on June 11, 2021.
The bids received are summarized below.
