CLAM BAY SURVEY REPORT
Dr. Dabees, Coastal Engineer with Humiston & Moore, provided a review and discussion of
the April 2025 Clam Pass survey report. Highlights included the following.
• The scope of the survey was more expansive than in previous years (since 2017) and included
intersects within sections A, B, C, and southward including Outer Clam Bay. Outer Clam Bay
was included to determine any long-term changes. The survey did not include the east side of
"the island" within Section C, as this area is not part of the permitted channel.
• Surveyors use eco-sounders and GPS locators to compile the data in this report.
• The tidal range in Outer Bay on average is greater than a foot, and more than half of that in the
Gulf.
• As described in the 2014 Updated Clam Bay Management Plan, the system is event (storm)
driven and consequently, dredge events are not performed on a scheduled cycle.
• The system is not designed to support navigation.
• The goal of the hand -dug channels is to improve the health of the mangroves.
• The sand overwashed along the perimeter of Outer Bay requires attention and has been
included in the next scheduled maintenance project.
• To the credit of Pelican Bay and the County, Clam Pass has been kept open since the 2012/2013
event, by conducting dredging events when appropriate.
• Cross-section cuts were reviewed as provided in the survey report; channel migration was
noted.
• Dredging can only be performed in those areas where we are authorized to dredge.
• The tidal range in Outer Bay is currently at .65, which is above the critical threshold of .5 (and
above the first alarm of .6). Although this data shows that no dredge is currently indicated, a
planned dredge at the end of the year is a preventative measure. This planned dredge will
provide a reset before the expiration of our permits.
• We have requested a two-year extension of our U.S.A.C.E. permit, which expires in 2026.
• The system currently behaves differently than it did 20-30 years ago due to approximately 75
feet of mangrove erosion (triggered by a large dredge project in 2007), which caused a change
in the curve of Clam Pass.
• The decline in seagrass acreage is typical of regional trends; factors affecting seagrass are
water clarity, water depth, dissolved oxygen, turbidity, and level of nutrients, which have all
been affected by the damage to the environment from recent storms.
• All of our bays, inlets, and estuaries have had impacts from recent storms.

not put in place in January. Mr. Coleman responded that initially we were unable to obtain any quotes
from our pre -approved qualified contractors, who were busy with other jobs. This caused a delay in
our project. Unfortunately, after we were able to obtain a quote, the FWC declined our project request
until we can document that there are no active turtle nests. Ms. Polke questioned whether the PBF
could have done the RFP. Dr. Dabees commented that there are only a handful of contractors who
would be capable of moving sand out of Clam Bay and onto the beach.
Mr. Sterk commented that Mr. Patrick Wack has brought concerns over areas of stressed
mangroves adjacent to inlets in Outer Bay. He noted that there is a permitted hand -dug channel in this
area which is included on the 2025 ETE plan for channel restoration.
Mr. Swider commented that PBF resiliency efforts will continue to receive more traction with
calls to step up improving the health of the mangroves. Mr. Rodburg commented that although the
mangroves have suffered in recent years, their health is improving, and that we will hold steady with
our policies and procedures which have been effective. Mr. Swider questioned how we could get out
the information contained in ETE Clam Bay Monitoring and Management annual reports to the
community. Mr. Rodburg commented that it is unfortunate that there is a lot of misinformation on
these topics out there in the public. Mr. Coleman commented that we continue to put out more and
more articles on these topics in the PB Post and PB e-blast but unfortunately, only 8% of PB residents
read these articles. Mr. Rodburg noted that residents focus on our beach erosion, which is an
observable condition. He suggested that staff puts together a simple Q & A on our beaches and
dredging, including the primary purpose (to maintain the health of our ecosystem) and constraints of
our permits.
Dr. Dabees commented that within two months of Hurricane Ian, the price of sand doubled,
and that we are competing with nearby entities for contractor work. He noted that the cost to the
County for beach restoration of Park Shore, Vanderbilt Beach, and the remaining Collier beaches is
approximately $20 million. Dr. Dave Trecker, Vice Chair of the County Coastal Advisory Committee,
commented that these costs will only increase in the future. Ms. Polke suggested that the PBF would
support contributing funds to beach restoration in order to protect their valuable assets. She questioned
what our FY26 beach renourishment budget of $4.5 million is for. Dr. Dabees responded that it is to
reimburse the County for the beach renourishment of that portion of Pelican Bay private beach which
is outside of Collier County's responsibility. He noted that the County pays for beach areas which are
within 'h mile of public access. Mr. Rodburg commented that we piggyback on the County's project
and pay for the renourishment of our private beach areas.
OPTIONS FOR LONG-TERM RESILIENCY OF THE BEACHES
Mr. Rodburg commented that the PBP has established subcommittees for Clam Pass and our
beaches, and suggested that once these committees are operational, members should attend PBSD
Clam Bay meetings for educational purposes. Ms. Polke commented that the PBF Board has suggested
that all PBF committee members should attend all PBSD meetings.
Mr. Rodburg suggested that the committee, in conjunction with our consultants, should look
at whether our plan to raise the berm up to seven feet is appropriate, or would a better height or a better
material be advantageous. He commented that the County's beach template is for 85 feet up to the
vegetation line (established by the County). Mr. Rodburg reported that at the last BCC meeting, an
audience member suggested enlarging the template width to increase protection. Dr. Dabees
commented that the permitting agencies want to ensure that the sand that we place on the beach does
not cover the nearshore hard bottom, and that if this were requested, that an environmental impact
study would be required. He noted that state and federal law manages impacts to environmental

resources. Dr. Dabees commented that in recent years, the U.S.A.C.E. spent $6 million on Southwest
Florida resiliency studies with no results. Mr. Rodburg concluded that at a future date this committee
will consider the feasibility of long-term resiliency alternatives.
FOLLOW-UP DISCUSSION FROM THE JUNE 11 PBSD BOARD MEETING
Ms. Polke requested clarification of our reclamation of 12,000 cubic yards of sand. Dr. Dabees
commented that our 2025 dredge plan estimates the removal of 12 — 13,000 cubic yards of sand from
Clam Pass. Mr. Rodburg noted that this sand is suitable for placement on South Beach. He noted that
we have three sources of sand which are (1) dredged sand from Clain Pass, (2) trucked -in sand, and
(3) recently deposited sand in Clam Bay (beyond the vegetation line).
PPT PRESENTATION ENTITLED "PROPOSED PBSD CLAM BAY NRPA
MANAGEMENT PLAN VS. 1998 CBRMP (ADD -ON)
Ms. Polke provided a 2013 PPT presentation entitled, "Proposed PBSD Clam Bay NRPA
Management Plan vs. 1998 CBRMP," which was found on the City of Naples website (author
unknown). Mr. Coleman commented that staff and Mr. Rodburg had not reviewed this presentation
and that it may not be factual. Mr. Rodburg questioned, (1) "What am I looking at?" (2) "To whom
and when was this presented? (3) Is this one person's opinion? and (3) Is this reliable?
Ms. Susan Devoe, a Seagate representative who sits on their board, commented that Seagate
residents are in lockstep with the PBSD and are not interested in navigation. Ms. Polke commented
that we can manage Clam Bay together with our neighbors. She provided personal pictures of Clam
Pass, showing changes from 2010 to 2024. Mr. Rodburg acknowledged that currently there is more
sand in Clam Bay than in the past, and asked Ms. Polke, "So what?"
Ms. Polke asked for a study of the wildlife that was once in Clam Bay and water flow that was
once in our ditches, that no longer exists. Mr. Coleman cormented that plenty of wildlife still exists
in Clam Bay and along the berm, and that we can provide wildlife pictures taken recently by staff and
residents.
Dr. Dabees commented that flood shoals are a protected environmental resource and that it is
unlikely we could obtain authorization from the agencies to dredge a flood shoal.
Mr. Rodburg commented that he did not see any value in this presentation, but that he would
review it again.
Dr. Trecker asked Ms. Polke, "From what professional engineering expert did you get the idea
of approving the dredging of cut 44?" Ms. Polke commented that this was done a long time ago. Dr.
Trecker suggested that Ms. Polke is presenting a proposal that she cannot justify. Ms. Polke
commented that she did not suggest any proposal; she asked whether the opening still exists. Mr.
Rodburg suggested that Ms. Polke does her homework and reads the ETE Clam Bay Monitoring &
Management annual report, before offering her opinions which are not based on facts, history or
science.
Ms. Polke questioned how the sand buildup has affected sea life in the bay and in the berm.
Mr. Sterk commented that his annual report, for the last ten years, includes seagrass and protected
species monitoring. Dr. Dabees questioned whether Ms. Polke has read the Clam Bay Management
Plan. Mr. Rodburg commented that this is our foundational document and suggested that Ms. Polke
reads it as a member of this committee. Mr. Rodburg questioned whether Ms. Polke is a representative
of the PBF, and noted that the PBSD has its own mission.
Ms. Polke commented that the PBF would like to know how we can renourish our beaches
before the 2025 hurricane season so that we can protect our assets. Mr. Rodburg commented that he

is as concerned about the beach as anyone, but that we work within the constraints of our system and
that we cannot renourish our beach until the County is ready to renourish Vanderbilt Beach. The PBF
cannot change this fact. Dr. Dabees commented that the Pelican Bay private beach segment is too
small to stand on its own for a beach renourishment project, and if it were undertaken, it is likely that
all of the sand would be washed away. The larger the project, the more stable the beach will be. He
noted that the PBSD reimburses the County for that portion of their beach renourishment project
related to our private beach. Dr. Dabees commented that it is unlikely that you could hire a contractor
or obtain a permit for a PB private beach renourishment project.
The meeting was adjourned at 11:06 a.m.
