Board reviews lake maintenance: compressor noise reduced but tone and Edgewater flooding prompt delays to plantings
Summary
Premier Lakes reported algae, removal of one shoreline palm, and a measured sound reduction after installing a cabinet around a compressor; Operations Manager Shane Willis said the aerator's tone remains a concern. Plantings at Lake E4-A are on hold pending agreement with the Edgewater Condo Association and further coordination.
Bill Kurth of Premier Lakes reported to the River Ridge CDD board on July 23 that seasonal algae was observed, a shoreline palm at Lake E7A was removed and a cabinet installed around a compressor reduced measured sound levels from about 64 decibels to about 52 decibels between the compressor and a screening line.
"The sound level has been reduced from 64 to 52 decibels," Kurth said, adding that plantings are scheduled to be installed in the near future. Operations Manager Shane Willis responded that "the issue is not so much about the decibels but it is the tone of the aerator," and the board discussed possibly moving the compressor and reviewing easement constraints.
Supervisor Bob Schultz summarized localized flooding concerns in Edgewater and recommended a meeting with Edgewater leadership and Cambridge Management to reach an acceptable solution regarding littorals and rip‑rap. The board reached consensus that Canna lilies should not be planted; staff will delay plantings in Lake E4-A until an agreement is reached with the Edgewater Condo Association and will resubmit a proposal.
Mr. Willis also presented the Annual Quality Assurance audit for lake maintenance and dry retention areas, noting high water levels this season but reporting no compliance issues and overall improvement under current maintenance. Staff will coordinate with Premier Lakes and report findings at the next meeting.
