CLAM PASS
AUGUST TIDAL RATIO REPORT
Dr. Dabees, Environmental Consultant with Humiston & Moore, reported that tidal ratios
remain consistently above the critical threshold; the numbers look good.
AUGUST AERIAL PHOTOS
Dr. Dabees reported that August Clam Pass aerial photos look good. Ms. O'Brien
commented that these photos were provided to the PBSD Board last week.
BACKGROUND ON COUNTY'S REQUEST AND RESPONSE
Mr. Dorrill commented on his recent meeting with Deputy County Manager Nick
Casalanguida, Mr. Callahan, Dr. Dabees and Ms. Jacob, whereby Dr. Dabees provided a
presentation on the Clam Pass dredging timeline over the last ten years and the related explanations
for our emergency dredging events. Mr. Dorrill reported that Mr. Casalanguida stated that the
presentation exceeded his expectations, and suggested that a video of Dr. Dabees presentation be
made in order for it to be readily available when needed. The committee and Mr. Dorrill agreed
to go ahead and create a video of Dr. Dabees' presentation. Mr. Dorrill also has learned that Mr.
McAlpin, Manager of the County Coastal Management Program, will be retiring this year.
Ms. O'Brien suggested that the Clam Bay Committee "be on the same page" as staff and
vice versa in regard to staff activities related to Clam Pass. Mr. Dorrill commented that Mr.
Casalanguida had requested the meeting with Dr. Dabees and staff whereby Dr. Dabees provided
his draft presentation.
POSSIBLE TALKING POINTS
Ms. O'Brien reviewed the possible talking points which were included in the agenda
packet. Ms. McLaughlin commented on the value of this information for future reference.
TIMELINE FOR DREDGING-RELATED ACTIVITIES
Ms. O'Brien commented on her request to Mr. Dorrill and Ms. Jacob (included in the
agenda packet) for a timeline of the dredging process, including recommended steps and
2

approximate time required for each step. She suggested 13 steps and asked that Mr. Dorrill and
Ms. Jacob provide comments/edits to these steps.
Dr. Dabees commented that per the Clam Bay Management Plan, Clam Pass can only be
dredged when conditions warrant it; dredging can never be a part of an automatic cycle. He noted
that it is very difficult to estimate the completion of all the procurement steps, and these steps are
the longest part of the pre-dredge process. Ms. McLaughlin commented that when conditions
warrant a dredge event to prevent the closing of Clam Pass, this becomes an urgent emergency
project,where"the usual"procurement process cannot be adhered to. Mr.Dorrill agreed and noted
that it typically takes six months to put a project out to bid through the normal County Procurement
Dept. process and that when dredging is urgently needed,we have no choice but to ask the County
to waive the normal sealed bid process.
ADVANCED BEACH RENOURISHMENT
Ms. McLaughlin commented on a recent County informational meeting on a possible
"super beach renourishment program." At the meeting it was stated that this issue is in the first
year of a 3-year study. Ms. O'Brien commented on the "Scope of work — Park Shore beach
renourishment" document which was added to the agenda packet. This document describes an
imminent truck haul beach renourishment project for Clam Pass Park,North Park Shore, and Park
Shore beaches. Dr. Dabees commented that Mr. McAlpin has provided him with all the data
related to this proposed beach renourishment project. No sand will be placed on the north side of
Clam Pass to ensure adequate space for sand disposal in case a Clam Pass dredging event suddenly
becomes necessary (per FDEP). Mr. Dorrill commented that historically the County manages all
of the beach renourishment programs, monitors all County beach widths, and always includes
Pelican Bay in their projects when appropriate. Ms. O'Brien suggested we obtain a copy of the
County's 2019 beach survey.
Mr. Streckenbein commented that Dr. Dave Trecker,former PBSD Board member, is now
a member of the County Coastal Advisory Committee. Mr. Streckenbein commented that he is in
touch with Dr. Trecker on a regular basis; Dr. Trecker has suggested that a super beach
renourishment program for Pelican Bay beaches would cost $2 — 2.5 million. Mr. Dorrill noted
that in the past Dr. Trecker suggested that$1 million should be in PBSD reserves to cover a typical
truck haul beach renourishment program. Mr. Dorrill suggested that we may want to update our
assumptions on the appropriate amount of adequate PBSD reserves for beach renourishment
purposes.
WATER QUALITY
COPPER RESULTS
Ms. O'Brien commented that copper results continue to look great.
PHOSPHORUS LEVELS IN CLAM BAY
Ms. O'Brien commented that phosphorus levels in Clam Bay continue to be problematic.
Ms. McLaughlin commented that a new County ordinance requires homeowners to perform
nutrient tests on their soil prior to adding phosphorus to their fertilizer.
COUNTY LAB REPORTS
Ms. O'Brien commented that the County Lab has switched over from monthly reporting to
quarterly reporting for our water quality testing results. She suggested that we ask Mr. Nosbel
3

September 10,2019
Perez, Supervisor of the County Lab, if it would be possible for us to receive monthly reports. Mr.
Dorrill will follow up with Mr. Perez. Ms. O'Brien also suggested that the committee and staff
have a conference call with Dr. Tomasko to discuss Clam Bay nutrient levels.
PO FOR WATER QUALITY REPORTS
Ms. O'Brien commented and staff confirmed that a request for quotes has been issued for
our water quality reports. Quotes are due Sept. 18.
CLAM BAY
HAND-DUG CHANNEL MAINTENANCE
Mr.Jeremy Sterk, Environmental Consultant with Earth Tech,provided a diagram of Clam
Bay which identified the areas of this year's completed hand-dug channel maintenance. He
reported that significant Hurricane Irma debris continues to be observed in the channels, and
suggested that this debris may be causing the high phosphorus levels observed in Clam Bay.
MANGROVES
Mr. Sterk provided the new infrared Clam Bay aerial photo for review by the committee.
He compared the observed mangroves from this photo to the 2017 photo, through the use of 38
grids. He noted general mangrove health improvement with minimal declines. However, "grid
#19" shows a specific area of die-off This area will be closely monitored going forward. Mr.
Sterk reported that he has identified repeatable exact locations from which to take periodic drone
photos so that mangrove health comparisons can be made over time.
SEAGRASS
Mr. Sterk reported that seagrass (predominantly shoal grass) acreage has declined slightly
to 3.53 acres. However, the seagrass is the healthiest he has ever observed.
CANOE TRAIL MARKERS 10 AND 12
Mr. Sterk reported that the County has re-installed the poles for canoe trail markers 10 and
12 and will re-install the signs for these two markers in the very near future.
SCAEVOLA TREATMENT
Ms. O'Brien commented that Mr. Sterk will work on developing a proposal for a future
scaevola removal project, to be included in a future PBSD budget.
CANOE TRAIL GUIDE
Ms. O'Brien commented that 25,000 new canoe trail guides have been printed and are
available to the public.
PELICAN BAY POST ARTICLES
Ms. McLaughlin provided draft articles on (1) the new canoe trail guide, (2) Bay Colony
beach dune swale, (3) mangrove channels, (4) the new County fertilizer & urban landscaping
ordinance, and(5)duckweed algae for the committee's review. The committee suggested that Ms.
McLaughlin include a discussion of the PBSD swale work completed in other communities, in
addition to Bay Colony, in the beach dune swale article. Ms. McLaughlin questioned whether the
fertilizer used by the PBSD contains phosphorus. Ms. Jacob will check into the level (if any) of

phosphorus in the fertilizer used by the PBSD. Ms. O'Brien suggested that Mr. Tim Hall proofs
these articles.
UPDATE ON MANATEE PROTECTION ZONE
Ms. O'Brien commented that the Pelican Bay Foundation was not successful in its appeal
for a designation of a manatee protection zone in Clam Bay.
