The motion carried unanimously. Ms. Hamilton motioned, Mr. Cullen seconded to approve the 7/11/23 meeting minutes as presented. The motion carried unanimously AUDIENCE COMMENTS None WATER QUALITY LANDSCAPING/LITTORAL PLANTINGS Mr. Rodburg commented that we have received the final revised 2022 Water Quality Report; the first version was reviewed and discussed by the Clam Bay Committee. He noted that this report recommended that the reduction in the amount of yard waste and fertilizer flowing into the water management system through public education may improve water quality in the system. Mr. Rodburg suggested that the PBSD has responsibilities by easement and permit for 43 lakes which include, (1) to maintain the functionality of the system, (2) to maintain the condition of the lakes for safety purposes, and (3) to ensure that the lakes are not sources of pollutants to Clam Bay. Mr. Rodburg noted that PB residents have expressed algae and water clarity concerns of our lakes. He commented that although our lake bottoms contain concentrations of nutrients/pollutants, it would be extremely costly to remove these materials. Mr. Coleman commented that water flow is key. Algae grows when there is no flow. He noted that the PBF is in the process of obtaining a quote to install a fountain in Oakmont Lalce which will greatly improve water flow. The electricity cost to run a fountain is minimal. As. Hamilton commented that there are two fountains in her association's lake, and that as a result, she has never seen any algae growth in this lake. Mr. Coleman commented that in the past, we have installed littorals in some lake bank areas, with little success, as weeds tend to grow in these areas, making the areas difficult to maintain. Mr. Coleman suggested that we invite our County Pollution Control Dept. to come out to give an educational presentation (on methods to improve water quality in our lake by limiting pollutants and discussing related County ordinances) at a PBF or PBSD meeting. Mr. Trent Waterhouse suggested that it may be more effective to provide such a presentation at a Presidents Council meeting and/or a PBPOA meeting. Attendees could then bring this information back to their respective landscapers. He also suggested that it may be possible for PBF's Lisa Warren to provide some sort of enforcement. No other enforcement entity currently exists. Mr. Rodburg suggested that a first step would be to reach out to the Presidents Council to explain our goals, followed by a second step to coordinate a presentation for them by the County Pollution Control Dept. Ms. McLaughlin commented that landscapers are required to go to training on fertilizer best practices. Mr. Coleman commented that the PBSD is changing from self -mulching of grass clippings to utilizing bag attachments to mowers to enable the clippings to be removed from the site. Pelican Bay Services Division Water Management Committee Meeting January 11,2024 Ms. McLaughlin commented that water quality testing in the past showed that phosphorus levels in the water flowing into Clam Bay were not excessive, but that there were higher levels of phosphorus within Clam Bay, which indicates rotting vegetation within the system as a probable source. Ms. Jacob reported that we continue to have quarterly water quality testing in 30 lakes, performed by the County Pollution Control Dept., who maintains a database of these results. Mr. Coleman suggested that Earth Tech, our Environmental Consultant, could provide some analyses on this data. Mr. Greenfield commented that there may be spikes in nutrients in the October/November and May time periods when landscapers typically fertilize. Mr. Rodburg commented that he would be interested in, (1) Are the levels of nutrients worse in some areas? and (2) Are the levels of nutrients getting better or worse over time? Mr. Dor ill suggested that we can reach out to Ms. Beth Schultz at the PBPOA to organize a Pollution Control presentation to the homeowners at a PBPOA meeting. He also suggested that we can reach out to several willing homeowners associations to let us know when their landscapers are performing their semi-annual fertilization, so that we could "follow behind them" to review their work. Ms. McLaughlin suggested that reaching out to the Presidents Council would be most effective. Mr. Waterhouse noted that Mr. Kim Rosenberg would be the contact for the Presidents Council. Mr. Coleman commented that roadway run-off also affects our water management system. Mr. Coleman commented that he is not in favor of planting littorals on lake banks. Ms. Jacob commented that we have no requirement to plant littorals, as our lakes were built prior to requirements put in place which mandate these plantings (Pelican Bay is grandfathered in). Or. Coleman commented that fountains are very effective in preventing algae. Once the first fountain in Oakmont Lake is installed, we can assess whether an additional fountain is warranted. Mr. Joe Lasa, PBF Purchasing Manager, commented that he will follow up on the status of the new fountain with the PBF. CURRENT AND FUTURE PROJECTS NEXT LAKE UP Mr. Coleman commented that the Community Center Lake is at the top of the list of our prioritized lake bank projects. However, at this time, we are holding off on developing a remediation plan because of the many unknowns including (1) PBF strategic plans for the Community Center, (2) PBF preferences, and (3) possible effects to the Community Center area from the planned construction of the pickleball courts. Mr. Coleman noted that this lake bank remediation may only require regrading and relandscaping. PIPE REPORTS Mr. Coleman reported that pipe cleaning work is underway at the Ritz and the Trieste. Pipe inspection reports of current ongoing projects have been included in the agenda packet. Camera pipe inspections by Shenandoah were completed in order to identify drainage issues. Pipe reports show that minor repairs are needed to correct minor root intrusion issues. Mr. Coleman commented that FY24 pipe repairs are funded out of budgeted operating expenses; however, in the future, we may set up a project for pipe repairs for budget purposes. Mr. Coleman noted that we have learned of a "pipe separation" on the golf course (next to the Sanctuary and Chateaumere), which will be our next repair project. c Pelican Bay Services Division Water Management Committee Meeting January 11,2024 CONTESSA/BAY COLONY CONSERVATION AREA Mr. Dorrill reported on a Jan. 12 scheduled meeting with the Bay Colony Association to look at an area of concern at the south end of the beach dune Swale adjacent to the Contessa and a conservation area that is contiguous to the Contessa to the south that is not owned by the County. No PBSD easement nor a part of a permit exists for this area of concern. There is a fairly significant mangrove die -off in this conservation area. Mr. Dorrill noted that further work in the dune swale may be warranted.
