AUDIENCE COMMENTS None MANGROVE DIE-OFF THA OCTOBER REPORTS Ms. O'Brien reported that the THA October report estimated that the mangrove die-off area has remained about the same. Ms. O'Brien reported observing significant stagnant water in the northern die-off area adjacent to Upper Clam Bay, on Friday Nov. 4. She observed no apparent drainage. OBSERVATIONS FROM NEW MANGROVE MONITORING PLOTS IN DIE-OF AREA Mr. Sterk commented that his observations show that the mangrove mortality appears to be almost 100% white mangroves with evidence of new red mangrove growth. He suggested letting the "natural progression" continue of red mangroves replacing white mangroves. H&M TIDAL RATIO DATA FOR OCTOBER Ms. O'Brien commented that the H&M tidal data shows slightly better ratios from the prior month. SET-BACK INFORMATION ON RETAINING WALL ALONG BAY COLONY ROAD Mr. Dorrill reported that based on our engineer's review of property lines and easements on or adjacent to Bay Colony Drive, PBSD has no roadway drainage easements in this area. Mr. Dorrill summarized that Ms. Jacob will provide the following Bay Colony Drive information at the next committee meeting: (1) final inspection reports, (2) one year warranty inspection report, and (3) clarification of access easements for Bay Colony Drive. Mr. Jim Carr, Agnoli, Barber & Brundage, will assist as necessary. HAND-DUG CHANNELS Ms. O'Brien suggested the need to explore the reason for the stagnant water not flowing into Upper Clam Bay via the hand-dug channels, and the reason for the water in Upper Clam Bay 2 Pelican Bay Services Division Clam Bay Committee Meeting November 9,2016 not flowing south through the entire Clam Bay drainage system. She commented that Mr. Hall observed no blockages in the hand-dug channels in his last report. Ms. Mary Johnson expressed concern over the drainage channels not functioning properly. INTERVENTION STRATEGIES By consensus, the committee agreed on intervention strategies to include (1) Mr. Sterk will look at water level logger data as compared to last quarter, (2) THA will look at current water levels in hand-dug channels as compared to April 2016 data, and (3) staff will ask H&M to explore water level data provided by the four Clam Bay tidal gauges. Mr. Hirniak suggested exploring a"hydraulic profile" of the Clam Bay drainage system. CLAM BAY MONITORING, WORK,AND REPORTS TREE TRIMMING AND EXOTIC TREATMENT IN FY17 Ms. Jacob reported that the PBSD received proposals for FY17 annual exotic maintenance &treatment services for the East Berm, West Berm, and Clam Bay NRPA. The job will be awarded to Earth Tech as the lowest and most responsive bidder, resulting in savings of approximately $23,400 from FY16. Work will be performed quarterly on the east and west berms, and annually on the Clam Bay NRPA. 2016 ANNUAL REPORT Mr. Dorrill commented that consultant work products for the 2016 Annual Report are due on December 15. AERIAL PHOTOS OF CLAM BAY Ms. O'Brien commented on the excellent quality of the Clam Bay aerial photos provided by Humiston& Moore, which will continue to be taken on a monthly basis. WATER QUALITY COPPER DATA FOR AUGUST Ms. O'Brien commented on the copper data provided by the County Lab for August, which showed copper exceeding FDEP acceptable limits at one site (Clam Bay-9). This site will continue to be monitored as this "exceeds" level has been observed for two consecutive months. Mr. Dorrill commented on his Nov. 10 meeting with Commissioner-Elect Solis, and will discuss that there has been a significant reduction of 60-80% in copper levels in Clam Bay and in Pelican Bay upland lakes as a result of the elimination of the usage of copper sulfate in 2013. TOMASKO QUARTERLY REPORT ON TP AND TN FOR MAY,JUNE,AND JULY Ms. O'Brien commented that the 3rd Quarter Tomasko report shows additional problematic areas of"exceeds the criteria" of phosphorus concentrations in Clam Bay; the report suggests that nitrogen concentrations are not currently problematic.
