ROLL CALL
All members were present and a quorum was established
AGENDA APPROVAL
Mr. Ventress motioned, Mr. Hirniak seconded to approve the agenda as amended
with the addition of discussion item #6a. The motion carried unanimously.
APPROVAL OF 02/02/17 MEETING MINUTES
Mr. Ventress motioned, Mr. Hirniak seconded to approve the 02/02/17 meeting
minutes as presented. The motion carried unanimously.
AUDIENCE COMMENTS
Dr. Trecker commented on Dr. Tomasko's 2016 Water Quality Report which indicates
that total phosphorus in Clam Bay exceeded FDEP criteria in 2016. Possible causes of high
phosphorus levels are, (1) inadequate tidal flushing in Upper Clam Bay, (2) lake discharges
containing high phosphorus levels, and (3) sediment recycle from plant/fecal buildup.
Dr. Trecker summarized comments by Dr. Tomasko during a recent conversation
including, (1) FDEP does not require specific Clam Bay copper measurements, (2) FDEP cited
Clam Bay as "impaired for copper" based on sampling from sites CB1, CB3 and CB6 and
therefore, it may be reasonable to monitor copper levels only at these three sites, (3) collecting
samples from berm areas for copper level monitoring may be meaningless as these areas are dry
or close to dry during parts of the year, and (4) hardness measurements should be taken at some
upland lakes.
Mr. Hall commented that copper levels have been monitored at 9 sampling sites, per the
Clam Bay Management Plan. He commented that Clam Bay is currently on "the planning list"
for copper by FDEP.
MANGROVE DIE-OFF
THA FEBRUARY REPORTS
Mr. Tim Hall reported (1) February observations indicate no expansion of the original
mangrove die-off area, and (2) some seedling regeneration/regreening can be observed in some
of the stressed areas.
H&M FEBRUARY TIDAL RATIO DATA
Dr. Dabees commented that the February tidal ratios are at less than preferred levels. He
suggested that this is a result of observed average water levels being lower than normal for the
month of February.
WATER LEVEL LOGGER DATA
Mr. Sterk commented that the water level logger data will be available next week.
ELEVATION AND BATHYMETRIC SURVEY RESULTS
Mr. Sterk provided data from the recently completed topographic survey, which included
three transects from the Strand wall to Clam Bay. Mr. Sterk and Dr. Dabees concluded that this

area is almost a flat plain. As a result of the flat topography, Mr. Hall concluded that increasing
the number or size of hand-dug channels would not result in any benefit.
Ms. Mary Johnson commented on sea level rise and possible effects on Clam Bay.
MID MARCH MONITORING OF MANGROVE PLOTS
Mr. Sterk commented that his mid-March mangrove plot monitoring report should be
available at the April committee meeting.
MONTHLY MANGROVE DIE-OFF MONITORING
Mr. Hall commented that March is the last month of his monthly mangrove die-off
monitoring contract.
MAINTENANCE OF HAND-DUG CHANNELS
Mr. Sterk commented that inspections of the hand-dug channels will be completed in
March/April, from which he will provide direction/information on troubled areas for targeted
maintenance work to our maintenance contractor.
ADDITIONAL CONSULTANT SUPPORT
The committee decided that no additional consultant support is necessary at this time.
Mr. Peter Duggan commented that the Mangrove Action Group has decided to finance up
to $10,000 for a PEM research test (alternative beach renourishment) to try to motivate the TDC,
PBF and others to take similar action. He extended an invitation to join Dr. Tonya Clayton
(author of"How to Read a Beach") for a walk on South Beach on March 22 at 7:30 a.m. and at
Clam Pass Park at 9:30 a.m.
INTERVENTION STRATEGIES
The committee agreed that no intervention strategies are warranted at this time.
CLAM BAY MONITORING IN 2017
Ms. Jacob commented that the new two year Clam Bay monitoring contract, awarded to
Earth Tech, will be brought to the BCC on March 14 for approval, and then commence at the end
of the month.
DREDGING FOLLOW UP (ADD-ON)
Mr. Dorrill commented on post-dredging permit requirements: Between March 15 and
April 15, our engineers will be performing compaction testing to determine whether beach tilling
will be necessary. All turtle nesting requirements will be completed by the County.
Dr. Dabees commented that no escarpment issues have been observed and monitoring
will continue.
WATER QUALITY MONITORING
COPPER RESULTS
Ms. Jacob commented that monthly copper results will be available from the County Lab
by next Friday.
2016 WQ REPORT
3
Pelican Bay Services Division Clam Bay Committee Meeting
March 2,2017
The 2016 Water Quality Report was discussed by Dr. Trecker under "audience
comments." Based on the recommendation by Dr. Tomasko, staff will add "hardness
measurements" at six berm sites and "clarity" at the nine Clam Bay sites to monthly water
quality testing by the County lab. Committee members noted that Dr. Tomasko did not report
that the County Lab elected to rerun seven of nine samples for Clam Bay copper in July 2016
and found only three of the samples exceeded the FDEP standard for copper.
2017 WQ REPORT
Staff provided a draft of the RFQ for 2017 Clam Bay Water Quality Monitoring &
Analysis. The committee made the following suggestions: (1) the 4 quarterly reports should
focus only on total nitrogen and total phosphorus, (2) the annual report should include TN, TP,
copper and dissolved oxygen, (3) the annual report should include an exhibit of sampling sites
and tables showing highlighted exceedances for TP, TN and copper, (4) report deadlines should
be 30 days following the receipt of County lab monthly data, and (5)the expectation is that these
reports will be prepared by a site specific water quality expert.
SEDIMENT TESTING FOR TP
Ms. Jacob is in the process of preparing an RFQ for sediment testing for phosphorus and
copper at 11 Clam Bay locations. The committee suggested and staff agreed to add the Vizcaya
lake as a 12th site.
NEXT MEETING: APRIL 6,2017
By consensus, the committee agreed that the next meeting of the committee would be
held on April 6 at 1:00 p.m.
ADJOURNMENT
The meeting was adjourned at 2:52 p.m.
