O'BRIEN WELCOMED OUR NEW COMMITTEE MEMBER MS. DENISE MCLAUGHLIN AUDIENCE COMMENTS Mr. Peter Duggan requested information on the trimming of mangroves about ten yards from the beach in Clam Pass Park, about two years ago. Mr. Dorrill responded that this area is outside our jurisdiction and suggested Mr. Duggan call Mr. Barry Williams, Director of County Parks & Rec. CLAM BAY MARCH MANGROVE MONITORING Mr. Jeremy Sterk, Environmental Consultant with Earth Tech, provided a table of the March mangrove monitoring plots. He noted that the health scores in the TH-5 area have slightly declined. All other monitored areas are stable or improving. He reported that Earth Tech has continued mapping additional hand-dug channels. This summer's hand-dug channel maintenance will be concentrated in the TH-5 area. He will provide a plan for this year's channel maintenance to Ms. Jacob so that the project can be bid out as soon as possible. CANOE TRAIL MARKERS 10 AND 12 Mr. Sterk reported on a recent conversation with Mr. Chris D'Arco, Sr. Field Inspector of the Collier County Coastal Zone Management, who suggested that the County may be able to re- install canoe trail markers 10 and 12 in July or August. Ms. Jacob commented that a permit modification would be required to change the location of any of these canoe trail markers. Mr. Dorrill commented that he would follow up on the re-installation of these two markers with Mr. Gary McAlpin, Manager of Collier County Coastal Zone Management. Ms. O'Brien commented that the PBF has never received the new updated version of the Clam Bay canoe trail brochure. Ms.Jacob commented that when the process of updating the canoe trail brochure began, we agreed to pay Earth Tech for working on the update, and Mr. Hoppensteadt agreed that the PBF would pay for printing. Mr. Dorrill will follow up on this issue with Mr. Hoppensteadt, and a new canoe trail brochure will be available to residents as soon as possible. HAND-DUG CHANNEL MAINTENANCE 2 Pelican Bay Services Division Clam Bay Committee Meeting May 9,2019 Mr. Sterk commented that he estimates this year's hand-dug channel maintenance to be approximately $30-35,000. SCAEVOLA TREATMENT Mr. Sterk provided an exhibit(included in the agenda packet) showing scaevola areas that are visible using aerial interpretation. He suggested that the next step would be to "ground truth" this documentation. He recommended focusing on areas with a tortoise population, as scaevola typically crowds out native vegetation. Mr. Sterk suggested that if we could piggyback with the County on a similar scaevola removal project, we could lower our overall cost. SUBMITTAL OF ARTICLES TO THE PB POST Ms. McLaughlin commented that a lot of information covered in this meeting would be of interest to our residents. She volunteered to draft a few educational articles for the PB Post for review by our board members. CLAM PASS APRIL TIDAL RATIO REPORT Ms. O'Brien reported that the April tidal ratios look good. APRIL AERIAL PHOTOS The committee reviewed April Clam Pass aerial photos. Dr. Dabees provided a brief overview of the inlet features and fundamentals of the Clam Pass system. Mr. Dorrill commented that monthly aerial photos include not only shots of Clam Pass, but also shots of those mangrove areas which have been historically stressed and those adversely affected by Hurricane Irma. Mr. Sterk noted that we are seeing mangrove regrowth in most of the stressed mangrove areas. The committee agreed that we should continue to include the ten monthly photos of Clam Pass in the PBSD Board Regular Session agenda packet. BATHYMETRIC SURVEY Dr. Dabees reported that the Clam Pass bathymetric survey work has been completed, and that the data should be provided to him next week. COST INFORMATION FOR DREDGING CLAM PASS Mr. Dorrill clarified that Mr. Swider had requested information (in Feb./Mar 2019) on payments to our consultants for Clam Bay (not Clam Pass dredging) as backup information for discussion by the Budget Committee on the possible budgeting of a new in-house environmental specialist. DATA ON CLAM PASS DREDGING Dr. Dabees commented that we are on schedule to discuss our historical data on Clam Pass dredging at our July committee meeting. This data will ultimately be provided to the County Manager's Office to address their concerns. WATER QUALITY NEXT QUARTERLY REPORT 3 Pelican Bay Services Division Clam Bay Committee Meeting May 9,2019 Ms. O'Brien commented that we are waiting on the January water quality data from the County Lab. The first quarter water quality report cannot be completed until this data is received. COPPER RESULTS Ms. O'Brien commented that during the first four months of this year, we only had one instance in our nine Clam Bay sampling sites where copper exceeded an acceptable level. UPDATE ON WIN Ms. O'Brien commented that information on WIN (Watershed Information Network)was provided in the agenda packet. She noted that the County Lab is entering data from 2017 to the present into WIN. IMPACT OF POND CONTAMINATION ON CLAM BAY Ms. O'Brien commented on possible impact of pond contamination on Clam Bay from the Easter Sunday sewer pipe break. She commented that the last County water quality testing report, dated April 26, showed two test sites (including the St. Maarten/St. Thomas pond) that were still out of compliance. Ms. Jacob commented that she will follow up on this issue with the County Pollution Control Division on May 10.
