CLAM BAY
ETE ANNUAL REPORT
Mr. Jeremy Sterk, consultant with Earth Tech, provided and reviewed the 2017 Annual
Clam Bay Monitoring & Management Report. Highlights of the report included the following:
• The health assessment scores of mangrove tree plots declined in 2017 (March to
September) resulting from the adverse effects of Irma. Mangrove recovery from Irma
will continue to be monitored; four plots will be added to specifically monitor this
recovery.
• Coastal scrub vegetation monitoring shows scrub habitat, in general, is in good condition.
• The observed gopher tortoise population shows an increase of approximately 18%; all
tortoises appear healthy.
• The acreage of scaevola (exotic plant) has increased, and it is recommended that the
PBSD plan an exotic removal project to target this vegetation.
• A dramatic loss in seagrass acreage has been observed, attributable to the June —August
conditions in Clam Pass. Ms. Mary Johnson suggested that last season's increase in boat
activity may have been a contributing factor to the reduction in seagrass acreage.
• November/December water levels appear somewhat higher than a year ago.
• There is significant hurricane debris in the hand-dug channels; the goal is to remove this
material in April.
• Recreational monitoring show markers and signage are in good condition except for
Marker 12,which was uprooted during Hurricane Irma.
• Archaeological sites are in good shape, with no signs of any disturbance.

CONTRACT FOR DEBRIS REMOVAL FROM HAND-DUG CHANNELS
Mr. Sterk commented that the specifications for the hand-dug channel debris removal
project will be developed subsequent to the completion of the waterway debris removal project.
CONTRACT FOR HAND-DUG CHANNEL MAINTENANCE
Mr. Sterk commented that the specifications for the hand-dug channel maintenance
project will be developed subsequent to the completion of the hand-dug channel debris removal
project.
CONTRACT FOR EXOTIC MAINTENANCE ALONG WEST SIDE OF BERM
AND IN COASTAL SCRUB
Mr. Sterk commented that the project for exotic maintenance along the west side of the
berm and in coastal scrub is out for bid and due back in two weeks.
SAFETY TRIMMING ALONG NORTH BOARDWALK
Mr. Bolick commented that his staff has completed the safety trimming of vegetation
along the north boardwalk.
CANOE TRAIL MARKER 12
Mr. Sterk commented that he will follow up with the County on reinstallation of Marker
12, which was uprooted by Hurricane Irma.
CLAM PASS
H&M ANNUAL REPORT
Dr. Mohamed Dabees, consultant with Humiston & Moore, provided and reviewed the
2017 Clam Pass Physical and Tidal Monitoring Report. Highlights of the report included the
following:
• Conditions at Clam Pass are stable but critical, and will continue to be monitored.
• An interim spring survey is recommended, if conditions remain as they are now,to assess
the inlet prior to the tropical storm season.
• Ms. O'Brien suggested discussing a plan to avoid an "emergency dredge." Dr. Dabees
commented that although an emergency cannot be preplanned, he suggested
contingencies be put in place to prevent a two month delay in emergency corrective
action (dredging), if required, as occurred in 2017. Dr. Dabees commented that the Clam
Pass Management Plan states that dredging or any intervention is a last resort.
Mr. Dorrill commented that per a discussion held last summer, the County Manager is not
willing to provide a "reserve" appropriation from the TDC, in case an emergency dredge is
required. Mr. Dorrill suggested making an educational presentation to the TDC on Clam Pass,
including how conditions can change quickly.
Mr. Sterk suggested putting out an RFP to prequalify dredging contractors.

Pelican Bay Services Division Clam Bay Committee Meeting
January 4,2018
Dr. Dabees provided the most recent (12/20/17) Clam Pass aerial photos for review by
the committee.
ESCARPMENT (ADD-ON)
Dr. Dabees and the committee discussed the current escarpment observed at PB South
Beach. Dr. Dabees commented that escarpments are sometimes self-correcting and that beach
management practice is that action should be taken if the escarpment is longer than 100 feet and
higher than 18 inches.
WATER QUALITY
DISCHARGE FROM MYSTIQUE CONSTRUCTION PROJECT
Ms. O'Brien commented that there is no longer any observable discharge from the I
Mystique construction project. Mr. Dorrill commented that the PBSD is eligible to review the
Mystique's de-watering records. He directed Mr. Sterk to continue to monitor the Mystique.
COUNTY LAB COLLECTING WATER SAMPLES
Mr. Bolick reported that the County Lab will be collecting water samples, going forward,
at a reasonable cost. The October WQ results are due this month. Ms. O'Brien reported that the
Tomasko WQ report is expected prior to March.
NEXT MEETING:
By consensus, the committee agreed that the next meeting of the committee would be
held on March 8 at 1:30 p.m.
