Adjournment ROLL CALL All members were present and a quorum was established Ms. McLaughlin motioned, Ms. O'Brien seconded to approve the agenda as amended with the addition of items #5ci and #8.5. The motion carried Mr. Weir motioned, Ms. McLaughlin seconded to approve the 10/27/2020 meeting minutes as presented. The motion carried unanimously. AUDIENCE COMMENTS None CLAM BAY HIGHLIGHTS AND RECOMMENDATIONS FROM ANNUAL REPORT Mr. Sterk, Environmental Consultant with Earth Tech, responded to questions/comments from committee members on his 2020 Annual Clam Bay Monitoring & Management Report. His comments included the following. • Scaevola is invasive to the gopher tortoise habitat. • The Clam Bay Management Plan includes archeological monitoring of three sites to ensure that these sites have not been disturbed. • There are four stressed areas of mangroves which we have been monitoring for several years. These areas are not increasing or decreasing in size. It is recommended that we continue site visits, drone monitoring, and photo documentation of these areas, on a semiannual basis. Maintenance work on hand cut channels this year will target these four areas. At this time, it is unknown if these channels exist in two of these areas. Ms. O'Brien commented that she would like the 2020 Clam Bay Monitoring Report to be posted on our PBSD webpage. Mr. Coleman commented that this report is not ADA compliant, and it may not be possible to post the report on our webpage. Ms. O'Brien suggested that staff problem -solves this issue. ESTIMATED COST OF IMPLEMENTING RECOMMENDATIONS Mr. Sterk commented that his recommendations would not cause any increase to the work order in place for Clam Bay monitoring by Earth Tech. PROPOSAL FOR SCAEVOLA TREATMENT Mr. Sterk reported that he is working on a scope and opinion of estimated cost for a Scaevola treatment proposal. Once completed, the project will go out to bid. He commented that 2 Pelican Bay Services Division Clam Bay Committee Meeting January 12,2021 a site visit with staff occurred last week to determine access, which is a major concern for this project. Mr. Sterk commented that the County's Coastal Zone Dept. has no immediate plans for any scaevola treatment projects. He noted that the Bay Colony Association has recently completed a "hand removal" scaevola removal project, and the PBF recently completed a scaevola removal project near South Beach just prior to their South Beach renovation project. Mr. Sterk commented that our project will be carefully scheduled to occur outside of turtle nesting season and shorebird nesting season. He recommended that after the project is completed, quarterly maintenance should be completed in the subsequent year, and then at lesser intervals in future years. He also noted that replanting will be required. UPDATE ON OTHER EXOTIC TREATMENT (ADD -ON) Ms. Jacob commented that the 2021 exotic vegetation removal project (including 13 tasks for Clam Bay and Water Management areas) has been awarded to Aquagenix, as low bidder. Ms. O'Brien asked if in FY2022 bids for Clam Bay exotic treatment could be requested separately from Water Management exotic treatment. Ms. O'Brien requested additional information on a targeted area (5.21 acres) for exotic removal. Mr. Sterk commented that this area was chosen for this year's project as it includes numerous large exotic hardwood trees. Ms. O'Brien suggested that staff and/or Mr. Sterk determine whether this area is part of the "wetlands area" (PBF property) or Clam Bay, UPDATE ON CANOE TRAIL MAI2I{ER 8 Mr. Sterk commented that he recently spoke with Mr. Chris D'Arco, Coastal Zone Management Division, who confirmed that the repair of canoe trail marker 8 is on his list of needed repairs. Mr. Sterk suggested the preemptive replacement of all the marker poles. Ms. O'Brien noted that the Clam Bay Report found that several of these signs are dirty. Mr. Sterk responded that he will look into whether these signs are "cleanable." Ms. O'Brien suggested the possibility of staff cleaning the canoe trail markers. DRAFT ARTICLE FOR PB POST Mr. Weir suggested that the article include a discussion of the decision to close South Beach for a brief time during the Clam Pass maintenance project, during the holiday season. Mr. Dorrill commented that it was the Pelican Bay Foundation who made the decision to close South Beach. This was clearly a safety issue. He noted that the original goal was for the project to be completed prior to the Christmas holiday. Dr. Dabees, Coastal Engineer with Humiston & Moore, commented that he coordinated with PBF staff on the day that regrading sand on South Beach had to occur. Ms. O'Brien suggested that the article address the reason why South Beach was closed at the last minute. Dr. Dabees commented that the one -day beach closure was just one day of inconvenience to PB residents. However, if a less flexible plan had been in place, then it may have been necessary to close the beach for one to two weeks. Dr. Dabees commented that on the day of the South Beach regrading, the PBF was informed, who in turn notified tram station attendants to announce the closure of South Beach for the day to residents. Mr. Dorrill commented that we are working on a communications plan for the sidewalk project. He suggested that we are careful when referring to our Clam Pass maintenance/dredging projects, and noted that the perception of a hydraulic dredging project is quite different from a maintenance regrading project. Ms. O'Brien commented that sand was dredged from Clam Pass Pelican Bay Services Division Clam Bay Committee Meeting January 12,2021 in December. Mr. Swider commented that our December Clam Pass project was a successful well - run project. BOATER SAFETY SIGNAGE UPDATE FROM COASTAL ZONE MANAGEMENT Ms. O'Brien commented that a map of Clam Bay identifying the locations of the five boater safety signs was included in the agenda packet. CLAM PASS UPDATE ON RECENT DREDGING AND LESSONS LEARNED Dr. Dabees provided a post -construction photo of Clam Pass to the committee. He commented on the recent Clam Pass project which included the following observations. • Our contractor TSI Disaster Recovery LLC provided us with excellent work. • The contractor, with great competence and equipment, was able to sweep Section "B" to our template, taking out 3000 yards of sand. • The County's Park Shore beach renourishrent project likely caused the excess sand to build up in Clam Pass. • Although the final survey has not been completed, it is estimated that 10,000 yards of sand were removed from Clam Pass. • Once the final survey is received, there will be a change order for the contractor, based on the survey. Mr. Dorrill reported that when we had notified Mr. Hoppensteadt, PBF President, that extra sand would be placed on South Beach, he agreed to pay for the sand, estimated at $40,000. Mr. Dorrill also noted that based on conversations with this contractor, that the contractor will continue to bid on our future projects. Ms. McLaughlin commented that a lesson learned would be that whenever the County does a beach renourishment project south of Clam Pass, that it is inevitable that a Clam Pass maintenance project will follow. Ms. O'Brien expressed concerns on the impact on Clam Pass if the County were to proceed in completing a beach resiliency project. RESULTS OF POST DREDGING SURVEY Dr. Dabees commented that the current bathymetric survey of all Clam Pass sections is in the process of being completed. NEXT BATHYMETRIC SURVEY Dr. Dabees commented that the last annual bathymetric survey was completed in May 2020. He has not made a decision on when to best schedule the 2021 annual survey. TIDAL RATIO RESULTS FOR DAYS SINCE DREDGING Dr. Dabees commented that he has not processed any tidal ratio data since the December Clam Pass project was completed. 2020 PHYSICAL AND TIDAL MONITORING REPORT DUE MARCH 22, 2021 4 Pelican Bay Services Division Clam Bay Committee Meeting January 12, 2021 Ms. O'Brien commented that the 2020 physical and tidal monitoring report is due on March 22, 2021, WATER QUALITY 2020 WQ REPORT DUE MARCH 22, 2021 Ms. O'Brien commented that the due date for the 2020 WQ Report is March 22, STATUS ON CONTRACTS FOR C.B. MONITORING AND WQ REPORTING (ADD -ON) Ms. Jacob commented that our existing Clam Bay monitoring contract with Earth Tech expires in March 2022. In anticipation of that expiration, staff will use the County's Professional Engineering Services for Environmental Engineering contract to bid out the next Clam Bay monitoring contract. Ms. Jacob commented that the existing WQ monitoring contract expires in June 2021. She discussed the following two options to replace this contract: (1) go out for bid under the County's Professional Engineering Services contract or (2) have Turrell Hall work as a subcontractor under the existing Earth Tech contract. NEXT MEETING Ms. O'Brien commented that the next meeting will be held on March 30, which will include discussion on the 2020 WQ Report and the 2020 Physical and Tidal Monitoring Report.
