Adjournment 1 Pelican Bay Services Division Clam Bay Committee Meeting March 30,2021 ROLL CALL Ms. McLaughlin was absent and a quorum was established AGENDA APPROVAL Mr. Weir motioned, Mr. Swider seconded to approve the agenda as presented. The motion carried unanimously. APPROVAL OF 01/12/2021 MEETING MINUTES Mr. Weir motioned, Mr. Swider seconded to approve the 01/12/2021 meeting minutes as presented. The motion carried unanimously. AUDIENCE COMMENTS None WATER QUALITY HIGHLIGHTS AND RECOMMENDATIONS FROM 2020 ANNUAL REPORT Mr.Hall,Environmental Consultant with Turrell,Hall and Assoc.,commented on the 2020 Water Quality Report, prepared by Environmental Science Assocs. (ESA). The report had been provided to the committee and is posted on the County's PBSD webpage. His comments included the following. • Phosphorus levels have decreased from last year,which may be a result of Hurricane Irma effects waning. • Copper levels have decreased from last year, which may be a result of the copper in the system from past years leaching out of the system. • ESA has recommended that we (1) explore whether nutrient levels in the reclaimed irrigation water have changed in recent years,and(2)explore whether the PB community's usage of reclaimed water has increased in recent years. Ms. O'Brien commented that PB community associations should be reminded that there is no need to fertilize their properties based on the high level of nutrients in the reclaimed water. 2021 REPORTS: SIX MONTH AND ANNUAL REPORT Ms. O'Brien suggested that we eliminate quarterly water quality reports,and continue with six-month and annual water quality reports. Mr. Hall agreed and noted that this change can be included in the new contract for water quality reporting. REVIEW AND POSSIBLY REDUCE PARAMETERS FOR BERM SITES Ms. O'Brien commented that currently the County Lab is analyzing 13 parameters for berm sites and 8 parameters for Clam Bay sites. Mr. Hall suggested that we could eliminate calcium and magnesium from the list of berm site parameters. Ms. O'Brien suggested that Ms. Jacob contacts the County Lab to reduce the berm site parameters by these two items. CLAM PASS HIGHLIGHTS AND RECOMMENDATIONS FROM 2020 ANNUAL REPORT 2 Pelican Bay Services Division Clam Bay Committee Meeting March 30,2021 Dr. Dabees,Environmental Consultant with Humiston&Moore, commented on his 2020 Clam Pass Physical and Tidal Monitoring Report which had been provided to the committee and is posted on the County's PBSD webpage. Highlights of his comments included the following. • A bathymetric survey was completed after December's maintenance project which cleared sections"A" and "B" and restored these sections back to design conditions. Section"C" contains some residual material. • At the end of March,there is a slight narrowing of the inlet mouth. • Conditions will continue to be monitored. • There are significantly wide beaches on both sides of the inlet. • No critical conditions are expected through the spring, and therefore, there is no need to perform another bathymetric survey in April/May. The next survey is recommended to be completed in 2021 after the tropical season, and just prior to the preparation of the annual report. 2021 REPORTS: BIANNUAL BATHYMETRIC SURVEYS Ms. O'Brien suggested that a bathymetric survey of all Clam Pass sections be completed twice per year. Dr. Dabees commented that although the Clam Bay Management Plan provides for an annual survey, he would be in favor of biannual surveys which would provide more data. Ms. O'Brien suggested that we budget for two surveys in FY2022 at a cost of$7,000 per survey. Ms. O'Brien provided a document which included a table of total volume of sand for 2018/2019 Clam Pass maintenance dredging projects (which was added to the record) and suggested that a similar table be included in future annual reports. Dr. Dabees agreed. TIDAL RATIO RESULTS FOR FEBRUARY Dr.Dabees commented that tidal ratios for February were above .70 and he expects March tidal ratios to continue to be above .70. CLAM BAY PROPOSAL FOR SCAEVOLA TREATMENT/REMOVAL Three options for scaevola treatment/removal with cost estimates were provided in the agenda packet. Mr. Sterk, Environmental Consultant with Earth Tech, recommended Option 3 which provides both the best methodology (materials are ground up in place) and least cost. He noted that a "tortoise agent" (FWC certified) must be onsite at all times during the project. This requirement may be fulfilled either by a FWC certified County employee or provided by the contractor. Mr.Sterk suggested that the project be timed so as to be least impactful to PB residents. He also noted that follow up maintenance work is critical. Mr. Sterk commented that the cost estimate of$100,000 for Option 3 is for 2 acres of designated scaevola areas, which is comprised of approximately 1.1 acres of NRPA areas and .9 acres of PBF property. Ms.Jacob and Mr. Sterk will review the Option 3 estimate and NRPA/PBF acreage percentages, and then explore PBF cost sharing for the project. Ms. O'Brien suggested that the committee had expected that the scaevola removal would be a multi-project. Mr. Sterk commented that although he would recommend completing the entire project in a single phase, a phased approach is also possible. Mr. Sterk also confirmed that replanting is a requirement. Mr. Fogg questioned whether scaevola treatment/removal is required. Mr. Hall responded that the Clam Bay Management Plan states that exotic vegetation will be kept under control. He noted that scaevola currently has about five percent coverage in Clam Bay, and that if unchecked, 3 Pelican Bay Services Division Clam Bay Committee Meeting March 30,2021 it will spread and the removal cost will increase. Ms. O'Brien also noted that scaevola negatively affects the gopher tortoise habitat. Ms. O'Brien suggested that when the project goes out to bid, we request quotes for the work using the Option 3 methodology and exclude work south of Clam Pass which is Clam Pass Park,the responsibility of another County division. DRAFT OF FY22 BUDGET Ms. O'Brien provided a draft FY22 Clam Bay budget in the agenda packet. She suggested that staff may need to tweak the estimated cost for scaevola removal and then include this project in the FY22 budget. Mr. Dorrill commented that he will check to determine whether the cost of the replanting(replacement of scaevola)would be eligible for TDC funding. If not, this expense would also need to be included in the FY22 budget. CANOE TRAIL MARKER 8 AND SIGNS NEEDING CLEANING Mr. Sterk commented that canoe trail marker 8 continues to be on the County's repair list. He also commented that he will work on canoe trail marker cleaning as part of his next project in Clam Bay. BEACH NOURISHMENT—UPDATE ON ENGINEERING WORK Mr. Dorrill commented that segments of the PB beaches were omitted from the County's RFQ for engineering work for the FY21 beach renourishment truck haul project, which would include the project design,preparation of plans, and estimation of quantities of sand needed. He noted that Deputy County Manager Dan Rodriguez is working with the Procurement Dept. and the Coastal Zone Management(CZM)Dept.to have the PB segments added to the RFQ for the County project. Dr. Dabees commented that based on the County's 2021 beach width survey, he would recommend nourishment of sections R34.6 to R36.5 in the area of the North Beach facility. The County's renourishment project will end at R30.5 in the Vanderbilt Beach area. He recommended that it would be best to taper sand from the south end of the County project area down to the beginning of the PBSD project area at R34.6. Mr. Fogg commented that from a budget perspective, we are estimating $500,000 - $1,000,000 for this project. However, if we have to include additional segments north of North Beach (area of taper), then the estimate may be $1.5 - $2 million. Ms. O'Brien noted that ultimately the PBSD Board will decide which sections to renourish. BOATER SAFETY SIGNAGE—UPDATE ON STATUS OF ORDINANCE Mr. Hall and Ms. Jacob commented that there is nothing new to report on boater safety signage in Clam Bay. Ms. O'Brien requested that staff requests a copy of the most recent CZM map of signs. ALGAE REMOVAL SKIMMER BOAT TEST Mr. Donill commented that we are in the process of testing a skimmer boat which mechanically skims algae off the surface of a lake. Ms. O'Brien suggested that this would be a topic for the Water Management Committee.
