Premier Lakes reports seasonal algae and reduces compressor noise; board delays plantings pending Edgewater agreement
Summary
Premier Lakes reported algae typical for the season, removed a palm tree from Lake E7A, installed a cabinet that reduced compressor sound from about 64 to 52 decibels but noted an objectionable tone; the board placed plantings for Lake E4‑A on hold until an agreement is reached with the Edgewater association and directed staff to study moving the compressor.
Bill Kurth of Premier Lakes told the River Ridge CDD on July 23 that lake levels and dry retention areas are generally in good condition but that seasonal algae growth had been observed. He said plantings are scheduled but that one palm tree on Lake E7A was removed during recent maintenance.
Kurth reported that a cabinet installed around a compressor on the Masters Lake reduced measured sound levels from roughly 64 decibels to about 52 decibels, which he described as acceptable between the compressor and the screen line; Operations Manager Shane Willis said the issue is less about decibel level than the tone of the aerator.
"It is the tone of the aerator," Willis said, and the board discussed potentially relocating the compressor and easement implications. Willis will coordinate with Bill and Alex Kurth on moving the compressor and will report findings at the next meeting.
Mr. Schultz summarized issues at Edgewater, including flooding, piping needs, littoral plantings on Lake E‑4A and rip‑rap; the board agreed that Canna lilies should not be planted and placed Lake E4‑A plantings on hold until an agreement with the Edgewater condominium association is reached through Cambridge Management.
In a related report, Willis presented the annual quality assurance audit for lake maintenance and dry retention areas, noting water levels were high and the audit will be done earlier next year; he said there were no compliance issues and that the lakes have improved under Premier Lakes’ maintenance.
Next steps: Mr. Willis will coordinate compressor‑relocation analysis with Premier Lakes and report at the next meeting; plantings for Lake E4‑A are on hold pending agreement with the Edgewater association.
