AUDIENCE COMMENTS None CLAM PASS UPDATE ON DREDGING, IMPACT OF SAND ON TURTLES, TIMING, EXPANDED TEMPLATE OPTIONS Dr. Mohamed Dabees, Coastal Engineer with Humiston & Moore, provided an update on our completed Spring Clam Pass dredging project. The project was at substantial completion on April 22. Cold fronts passed through during the project, causing the removal of more quantities of sand than expected on the original template. Dr. Dabees reported that the Pelican Bay Foundation received 8,255 yards of sand and was invoiced $66,000 for the yards planned for in the original template. He noted that a total of just over 17,000 yards of sand were removed from the Pass. Dr. Dabees commented that this project was the first full dredging project since our last project in 2018, with two partial dredge events within this four-year time period. He suggested that this is reasonable. Dr. Dabees suggested that in the future, the PBSD needs to coordinate with the County on Park Shore and Clam Pass Park beach renourishment projects and discuss the unintended consequences of the migration of sand northward into Clam Pass. Mr. Dorrill commented that the PBF, a major stakeholder in the project, has been an excellent partner to work with. He noted that there are now historic levels of sand on the beaches both north and south of the inlet. Mr. Coleman commented that staff has "knocked down" escarpments on the north side of the Pass four times since project completion, which may assist sea turtle crawls. Mr. Dorrill commented that on two occasions, the PBSD offered private briefings to the Seagate community, which were declined in favor of making complaints to the Coast Guard. The committee, Mr. Dorrill, and Dr. Dabees discussed possible methods of stabilizing the Pass, in addition to dredging, as follows. • Add mangroves to the area at the mouth of the Pass. The effectiveness and longevity of installing mangroves in this area is unknown. Residents would likely respond negatively to the loss of beach area. Dredge and re-establish the former inlet located just south of the existing inlet. Dr. Dabees suggested that environmental groups would express resistance to this idea. Mr. Dorrill suggested that the materials in the former inlet may not be beach compatible. Extend the fill template on the north side of the inlet (to accommodate more yards of sand) through a permit amendment. Dr. Dabees noted that costs would be much higher to transport the sand further north. Pelican Bay Services Division Clam Bay Committee Meeting July 6, 2022 2022 MEAN TIDE RATIOS Dr. Dabees commented that we continue to monitor monthly tide ratios. He noted that Earth Tech takes care of any necessary tide gauge maintenance/repairs. DATE FOR 2021 PHYSICAL AND TIDAL MONITORING REPORT FROM DR.DABEES Dr. Dabees commented that the 2021 Physical and Tidal Monitoring Report is underway and will include all of 2021, up through and including May 2022. A survey of the Pass in May measured sand quantities. COMMUNICATING WITH SEAGATE AND COAST GUARD Ms. McLaughlin commented that we need to improve our communication with the Seagate community and the Coast Guard on future dredging projects. CLAM BAY PREAPPLICATION MEETING WITH ARMY CORPS OF ENGINEERS & FDEP Mr. Jeremy Sterk, Environmental Consultant with Earth Tech, commented that the annual hand -dug channel maintenance work has been completed. He provided "before and after" photos of several of the channels as well as a map of this year's maintenance work. He will work on an assessment and plan of where hand -dug channels could be added to improve water flow, and will bring this back to the committee before beginning the regulatory agency approval process. No regulatory agency meetings have been scheduled at this time. Mr. Dorrill commented on an area southwest of the Contessa, where it has been determined that the standing water in this area has resulted from a lack of maintenance in their drains and cross culverts through their private road. This area is a conservation area, owned by the Bay Colony Association. Mr. Dorrill noted that historically we have only done maintenance work on publicly owned conservation areas, and that significant environmental permitting would be required to extend the beach dune Swale southward. UPDATE ON COUNTY'S EXOTIC REMOVAL AND llUNE RESTORATION S. Jacob reported that the County's Coastal Zone Management Division (CZM) will be going out to bid for their• coastal scaevola removal project, and will include Pelican Bay in the bid as a "bid alternate." Once bids are received, the PBSD can then make a decision on whether to participate in the project. COMPLETED CZM CANOE TRAIL MARKER REPAIRS Mr. Sterk commented that he took photos of all the Clam Bay canoe trail markers, and forwarded them to CZM to review. They will evaluate which markers require repairs or replacement. ARE OYSTERS VIABLE IN CLAM BAY? Ms. McLaughlin commented that the City of Naples has received a grant for an oyster restoration project in two locations. Mr. Sterk commented that he will research their project. Mr. Dorrill commented that there were clams in Clam Pass in the past. He suggested that we explore "seeding" clams and/or oysters in Clam Pass. Mr. Sterk will research both possibilities. RECLAIMED WATER USAGE AND IMPACT ON PHOSPHORUS LEVELS 3 Pelican Bay Services Division Clam Bay Committee Meeting July 6, 2022 Ms. McLaughlin commented that Clam Bay is impaired for phosphorus levels. She provided (by reading out loud) the PBSD reclaimed water usage from 2018 to 2022, which shows a dramatic increase in usage. Ms. McLaughlin commented that the County has indicated that they have no plans to upgrade their water treatment plant to reduce the level of phosphorus in the reclaimed water, unless the State changes their standards. Mr. Sterk commented that although the water usage has significantly increased, there does not appear to be an equal increase in the phosphorus levels in Clam Bay per our recent water quality data. Ms. McLaughlin questioned whether the PBSD has a permit for our reclaimed water usage and whether there is a limit on our usage. Mr. Dorrill responded that we will look into these issues as well as research the causes for the dramatic increase in usage over the last four years. CLAM PASS/BAY REPORTS AS OP NLY 2022 Ms. McLaughlin commented on the chart that she prepared (included in the agenda packet), which provides information on all of the reports that the PBSD collects, relating to the requirements of the Clam Bay Management Plan. The chart includes the entity responsible for preparing each report, as well as frequency, purpose, and dates. Dr. Dabees suggested that the frequency for his Clam Pass Physical and Tidal Monitoring Report should show "annual."
