Pelican Bay Services Division Water Management Committee Meeting

APPROVAL OF 11/18/16 MEETING MINUTES
Mr. Streckenbein motioned, Dr. Trecker seconded to approve the 11/18/16
meeting minutes as presented. The motion carried unanimously.
AUDIENCE COMMENTS
Mr. John Hughes, President of the Avalon Community Association, requested that
the PBSD install blue tilapia in Avalon's lake, instead of aerators. He commented on his
community's opposition to the noise generated by an aerator.
Ms. Ellie Tracy, Avalon board member, commented on the lack of littoral
plantings in the Avalon lake and the severe erosion of the lake bank which has resulted in
extensive irrigation pipe repairs.
Ms. Anne Georger-Harris commented on the high density of residences in Avalon
and her opposition to the installation of any noise-generating aerators.
Dr. Trecker commented that he cannot support adding blue tilapia to an additional
lake. Numerous consultants and other communities have concluded that negative
consequences from blue tilapia include (1) any beneficial results from blue tilapia are
transient, (2) blue tilapia will eat the lake's littoral plants, and (3) negative consequences
of ammonia-rich fecal matter generated by the blue tilapia.
The committee and staff agreed to put the Avalon lake aerator installation on hold
and expedite littoral plantings in this lake.
NORTH BERM RESTORATION & REPLACEMENT OF BAHIA SOD
PROJECTS
Dr. Trecker recapped two projects under consideration for a total of$86,000: (1)
east side erosion of the north berm from the north tram station to the Montenero for
$41,000 and (2) addition of riprap on the west side of the north berm from the Commons
to the north tram station for $45,000. Our Agnoli, Barber, & Brundage consultant, Mr.
Jim Carr commented that the first project is a structural issue, is not an emergency, and
could wait another year; the second project may be completed for aesthetic reasons. By
consensus, the committee agreed that the first project should be built into the FY18
budget and the second project should be part of a master priority list of lake bank
projects.
PROBLEMS WITH EXISTING SOLAR POWERED AERATORS
Mr. Cravens commented on staffs recorded observations of eight solar powered
aerators on nine days, as provided in the agenda packet, which shows that five of these
eight aerators are not functioning continuously, as designed. Mr. Bolick commented that
technicians are still trouble-shooting these malfunctioning devices. The aerators have a
two-year warranty on parts, one year on labor. At the recommendation of the committee,
Mr. Bolick will provide an update on our aerators to the full board on Feb. 1.
MR. STRECKENBEIN LEFT THE MEETING AT 3:12 PM
2017 AERATOR INSTALLATION
By consensus, the committee agreed that no new aerators should be installed in
2017 until all of the existing aerators are functioning properly.

TRIAL LAKES REPORT
Dr. Trecker commented on his observations of the four bacteria test lakes. He
commented that three out of the four test lakes appear pristine and algae free. Bacteria
may not be working as well in the St. Maarten/Commons lake as this lake has no aerators.
STATUS OF "MICROFLOC" TESTING
Ms. Jacob reported that she has a February conference call set up with Mr.
Raphael Vazquez-Burney of CH2M Hill to discuss the logistics of the microfloc testing.
Mr. Bolick reported that the Club Clubhouse lake and the Naples Grande front lake have
been selected for this testing.
PROPOSAL FOR DEALING WITH LAKE BANK EROSION
Mr. Tom Barber, our Agnoli, Barber & Brundage consultant, summarized his
$37,200 proposal to provide a master priority list of lake bank erosion projects. Ms.
Jacob strongly recommended this project. Mr. Bolick commented that $130,000 is
currently available in the PBSD budget for lake bank erosion projects.
Dr. Trecker motioned, Mr. Streckenbein seconded to recommend to the full board
to do the $37,000 study by Agnoli, Barber, & Brundage. After discussion by the
committee, Dr. Trecker withdrew his motion, and Mr. Streckenbein withdrew his second.
By consensus, the committee agreed that Mr. Tom Barber would make a presentation to
the full board on Feb. 1 regarding a proposal for a study of lake bank erosion to include
45 lakes and the berm erosion, resulting in a priority list of repair projects.
INPUT FROM COLLIER COUNTY PRESIDENTS COUNCIL
Dr. Trecker commented on the Collier County Presidents Council he attended
with Ms. Jacob where attendees discussed their communities' successes with various lake
algae control methods. He commented that some communities have experienced
significant success with bacteria. Mr. Bolick commented that it is difficult to quantify the
effectiveness of bacteria in PB test lakes since these lakes are also subject to chemical
spraying. He commented that bacteria cost per lake is approximately $600 annually.
ADJOURNMENT
The meeting was adjourned at 3:43 p.m.
