Adjournment 1 Pelican Bay Services Division Clam Bay Committee Meeting March 7,2019 ROLL CALL Mr. Swider was absent and a quorum was established AGENDA APPROVAL Mr. Hirniak motioned, Ms. O'Brien seconded to approve the agenda as amended with the additions of items #5c and #6d. The motion carried unanimously. APPROVAL OF 01/03/19 MEETING MINUTES Ms. O'Brien motioned, Mr. Hirniak seconded to approve the 01/03/19 meeting minutes as presented. The motion carried unanimously. AUDIENCE COMMENTS None WATER QUALITY ANNUAL WATER QUALITY REPORT Mr. Tim Hall, Environmental Consultant with Turrell,Hall & Assoc., commented on the 2018 Annual Water Quality Report, prepared by Dr. David Tomasko, which has been posted on the PBSD website. Notes on the annual report, prepared by Ms. O'Brien, were included in the agenda packet. Comments by Mr. Hall included: 1. Phosphorus issues (out of compliance per state criteria) are widespread throughout the Clam Bay system and are likely a result of the continued plant decomposition in the aftermath of Hurricane Irma. Raised levels of nitrogen and phosphorus continue to be observed not only in Clam Bay, but are also widespread in the SW Florida area. It is expected that these levels will decline over the coming months and we will continue to monitor them. The bird rookery in Upper Clam Bay may have some potential impacts to phosphorus levels in Upper Clam Bay,but it is too separated to affect the whole system. 2. Copper seems to be more of an issue (not out of compliance per state criteria) in Upper Clam Bay which could be occurring from re-suspension of copper sulfate from past usage. The committee suggested that Dr. Tomasko include a table of copper values at stormwater pond sites for the prior 12 months in each quarterly report(similar to the table included in the annual report). 3. At some sites, dissolved oxygen is just barely out of compliance with state criteria. COPPER RESULTS AND DETECTION LIMITS Ms. O'Brien commented on the copper table (included in the agenda packet) which shows November and December results. There was only one instance of copper being out of compliance per state criteria. Mr. Hall commented that the County Lab is diluting the samples (due to the salinity level)which may skew the copper results higher. CLAM PASS FEBRUARY TIDAL RATIO REPORT Ms. O'Brien reported that the February tidal ratio report is excellent. Dr. Dabees commented that these ratios are at the same levels as the post-dredging timeframe. FEBRUARY AERIAL PHOTOS 2 Pelican Bay Services Division Clam Bay Committee Meeting March 7,2019 The committee reviewed a January Clam Pass aerial photo. DATA ON DREDGING EVENTS AND EROSION NEAR CLAM PASS FROM 1999 TO PRESENT Dr. Dabees commented on dredging events from 1999 to the present, which show that dredging is event driven. He plans on a one-year anniversary post dredging survey to be completed April/May 2019 and will include this data in a report discussing justification for emergency dredges. He expects this report to be completed in July,to be followed by review and approval by the Clam Bay Committee and PBSD Board, and subsequent submittal to the County Manager's Office by the end of FY19. TIMELINE FOR DREDGING (ADD-ON) Ms. O'Brien suggested that we be more proactive when tidal ratios fall towards .5 and try to avoid an emergency dredge action. Dr. Dabees commented that a 3 to 4 month dredge response is a quick response. He also commented that we have always followed the Clam Bay Management Plan and we begin a dialogue with the County when tidal ratios fall below .5. CLAM BAY CONTRACT FOR MONITORING Ms. O'Brien commented that the new contract for Clam Bay monitoring will go to the BCC for approval this month. HAND-DUG CHANNEL WORK Mr. Sterk commented that he will work with Ms. Jacob to develop a scope of work for hand-dug channel work in FY20 and provide a suggested amount to be included in the FY20 budget. SCAEVOLA WORK IN FY20 Mr. Sterk commented that he will work with Ms. Jacob to develop a scope of work to map the dense scaevola patches in FY20 and provide a suggested amount to be included in the FY20 budget. CANOE TRAIL MARKERS 10 & 12 Mr. Sterk commented that the County has made no progress in reinstalling canoe trail markers 10 and 12. Committee members and the consultants discussed repositioning the markers in the area of the Clam Pass inlet, and it was decided that Mr. Sterk will develop a proposal to reposition a few of the markers and possibly add a few informational signs in this area. DRAFT OF FY20 CLAM BAY BUDGET Ms. O'Brien provided a draft FY20 Clam Bay budget which was included in the agenda packet. She commented that 45% of Ms. Jacob's salary is included in the Clam Bay budget; she will explore whether this budget allocation is realistic. Mr. Sterk commented that he will provide a recommended FY20 budget for hand-dug channel maintenance and scaevola treatment within 30 days. NEXT MEETING: 3 Pelican Bay Services Division Clam Bay Committee Meeting March 7,2019 Ms. O'Brien commented that this would be Mr. Hirniak's last committee meeting as his PBSD Board term expires at the end of the month and she thanked him for his service. By consensus,the committee agreed that the next meeting of the committee would be held on May 9, 2019 at 1:30 p.m. OTHER COMMENTS Mr. Hall commented that (1) the renovation of the beach store (by the PBF) at PB South Beach is about to start, and (2) the St. Kitts condo has plans to expand their pool area over the PBSD drainage easement, but no PBSD Board or Crown Colony Board approval has been obtained.
