AUDIENCE COMMENTS
None.
OLS SWALE PROBLEM AND POTENTIAL SOLUTIONS
Mr. Cravens provided a brief background and description of the Oak Lake
Sanctuary swale drainage issues. Ms. Jacob commented that an Oak Lake Sanctuary
bleeder modification project to improve drainage and lower the level of the lake is currently
out for bid. The committee chose to table further discussion on this issue,until the project
is completed, and the results can be assessed.
STATUS OF DRAINAGE PROBLEM BETWEEN THE DORCHESTER& THE
GROSVENOR
Mr. Cravens provided a brief description of the drainage issues in the grassy
landscaped area between the Dorchester and the Grosvenor, for which the PBSD has a
drainage easement. Ms. Jacob commented that our engineer AB&B has been tasked to
develop a drainage improvement solution and has already begun surveying the pipes and
drainage areas. The committee chose to table further discussion on this issue until a
solution is proposed.
POTENTIAL LAKE BORDERS/MODIFICATIONS FOR THE REDUCTION OF
LAKE ALGAE
Dr. Chicurel provided photos of the negative effects to our lakes from grass and
weed-eater clippings. He suggested that the committee look at creating a border around
each lake, as a method of preventing the clippings from entering the lakes. He noted that
the community of Mediterra has 8 — 10 feet of lilies surrounding each lake. Mr. Cravens
commented that littoral plants are expensive to install and labor intensive to maintain. Mr.
Shepherd commented that our workers need to be reminded that clippings should never be
tossed in the lakes.
Methods of algae reduction were discussed by the committee. Mr. Shepherd
questioned whether individual lake owners could supplement PBSD algae suppression
methods in our 45 lakes. After discussion, the committee agreed that owners should have
this ability, providing that they were to obtain pre-approval from PBSD staff. The
committee agreed that this issue should be discussed by the full PBSD Board.
Mr. Swider questioned what the cost would be to change over our irrigation water
from reclaimed water to potable water. County reclaimed water contains nutrients which
cause an increase in lake algae. The committee requested that staff investigate the
feasibility and cost of replacing Pelican Bay recycled irrigation water with potable water.
BLUE TILAPIA LAKES
The committee reviewed photos of the 20 lakes where blue tilapia were installed in
May 2018. Minimal algae was observed on the surface of these lakes. The committee
discussed whether blue tilapia could cause an increase in the level of ammonia in the lakes.

Pelican Bay Services Division Water Management Committee Meeting
October 18,2018
The committee suggested that staff look at before and after (blue tilapia installation)
ammonia levels in three lakes, as well as ammonia levels in three lakes where tilapia have
never been installed.
Mr. Shepherd motioned, Mr. Damouni seconded to recommend to the full
board that we expand the blue tilapia stocking to all 45 lakes. The motion
carried unanimously.
WATER QUALITY TESTING (ADD-ON)
Not discussed.
MYSTIQUE RUNOFF (ADD-ON)
Ms. Jacob provided photos of the runoff from the Mystique construction site into
the water management canal that runs along the berm. She commented that the County
Pollution Control Division was contacted, and after a site visit, they requested that the
condominium management team replace a catch basin filter and place some turbidity
barriers in the swale along the berm.
Mr. Cravens and Mr. Shepherd commented on Mystique construction workers
performing work before 7 a.m., while it is Pelican Bay Foundation general policy not to
allow any construction work to begin prior to 7 a.m. Ms. Jacob will notify Mr. Laney
(Pelican Bay Foundation) of these observations and will report back to the committee.
AERATION PROJECT BIDS RECEIVED (ADD-ON)
Ms. Jacob commented that two bids were received for our aeration repair project
(Hurricane Irma damage), with Aquagenix being low bidder. Mr. Shepherd commented
that Aquagenix is not a reliable vendor(based on our past experience with this vendor)and
that this vendor should be excluded from consideration.
ADJOURNMENT
The meeting was adjourned at 4:13 p.m.
