Premier Lakes reports algae and maintenance progress; aerator sound reduced but tone remains a concern
Summary
Premier Lakes told the River Ridge board that routine maintenance has kept lakes and dry retention areas in good condition, but algae was observed; a cabinet reduced one aerator’s measured sound from 64 to 52 decibels though staff said the tone—not just decibel level—remains an issue and staff will evaluate moving the compressor.
Bill Kurth of Premier Lakes updated the board on lake maintenance, saying the lakes, preserves and dry retention areas are "in good shape" though algae growth was observed as a basic maintenance condition. Kurth noted that a palm tree on the shoreline of Lake E7A had been removed and that plantings are scheduled to be installed in the near future.
Kurth reported that a cabinet installed around the compressor system at the Masters Lake reduced the measured sound level from 64 to 52 decibels, which he described as acceptable in his view; Operations Manager Shane Willis said during the lake audit that the principal concern is the tone of the aerator rather than the decibel reading alone. Discussion focused on possibly relocating the compressor given easement constraints and the board asked staff to coordinate with Premier Lakes to consider moving the compressor and report findings at the next meeting.
Kurth said plantings for Lake E4-A will be delayed until the Edgewater Association reaches agreement; the board agreed that Canna lilies should not be planted and staff will resubmit the proposal once consensus is achieved. Kurth left the meeting after his update.
