Lake maintenance update: compressor noise reduced and plantings delayed after Edgewater concerns

Bill Kurth of Premier Lakes, Inc. reported to the River Ridge board that the lakes, preserves and dry retention areas are in generally good condition but that seasonal algae growth has been observed. Kurth said a palm tree on the shoreline of Lake E7A was removed as part of routine maintenance.

Regarding noise at the Masters Lake, Kurth said a cabinet was installed around the compressor system and "the sound level has been reduced from 64 to 52 decibels," which he described as acceptable at the midpoint between the compressor and the screen line. Operations Manager Shane Willis said the issue is not solely measured decibels but also the tone of the aerator, and he and Kurth will coordinate with Alex Kurth to consider moving the compressor and will report findings at the next meeting.

Chair Bob Schultz summarized flooding and littoral plant concerns in Edgewater and recommended meeting with Tim Wilkin at Edgewater to seek solutions. The board reached consensus that Canna lilies should not be planted; plantings in Lake E4‑A will be delayed until an agreement is reached with the Edgewater Condo Association through Cambridge Management.

Separately, the annual quality assurance audit for lake maintenance and dry retention—presented by Mr. Willis—noted that water levels were high this season but found no compliance issues; Willis said the audit will be performed earlier next year.

Next steps: Premier Lakes and operations staff will investigate options to address the aerator tone, report back on whether the compressor can be moved, and return any planting proposals after agreement with the Edgewater association.
