Premier Lakes reports algae, lowers compressor decibels; board to study aerator tone and delay Lake E4-A plantings
Summary
Premier Lakes updated the River Ridge board on lake maintenance July 23: seasonal algae was noted, a palm at Lake E7A was removed, and measured sound at Masters Lake dropped from 64 to 52 decibels after installing a compressor cabinet; staff said the aerator's tone remains a concern and plantings in Lake E4-A are on hold pending agreement with the Edgewater Association.
Bill Kurth of Premier Lakes told the River Ridge CDD that the lakes, preserves and dry retention areas are in good condition but, given the time of year, seasonal algae growth was spotted. He said a palm tree on the shoreline of Lake E7A was removed and that plantings are scheduled to be installed in the near future.
On the Masters Lake compressor, Mr. Kurth said a cabinet was installed around the compressor system and “the sound level has been was reduced from 64 to 52 decibels,” which he viewed as acceptable. District Operations Manager Shane Willis said the concern is not only the decibel level but “the tone of the aerator,” and staff will coordinate with the Kurths to consider moving the compressor and report back at the next meeting.
Supervisor Bob Schultz summarized additional flooding concerns in the Edgewater area and recommended installing piping, adding littorals on Lake E-4A and rip-rap. The board agreed that Cana lilies should not be planted and decided to delay plantings in Lake E4-A until an agreement with the Edgewater Association is reached. Mr. Kurth left the call after the discussion.
Mr. Willis also presented the Annual Quality Assurance Audit for lake maintenance and dry retention areas, reporting water levels were high and recommending the audit be performed earlier next year; overall he reported no compliance issues and said the lakes have improved under Premier Lakes' maintenance.
