Pelican Bay Services Division Water Management Committee Meeting
February 1, 2021
Mr. Streckenbein motioned, Mr. Weir seconded to approve the agenda as
presented. The motion carried unanimously.
Mr. Weir motioned, Mr. Streckenbein seconded to approve the 1/23/20
meetine minutes as presented. The motion carried unanimously.
AUDIENCE COMMENTS
Mr. Fabregas requested that PBSD staff research the possibility of obtaining
easements for lakes 1 and 2 in Basin 1 (located within the Waterside Shops parcel), which
would make the PBSD responsible for servicing these lakes, which are interconnected with
the Pelican Bay master drainage system. He would like the PBSD to ultimately obtain
BCC approval to add these easements to the list of PBSD responsibilities.
Mr. Dorrill commented that historically the PBSD has had no easements for these
two lakes. He noted that he has recently had a discussion with the Waterside Shops
management on this subject.
Ms. O'Brien commented that there are 13 additional private lakes, connected to the
the PB master drainage system, for which the PBSD has no easements. She suggested that
the full board should have a discussion on whether to explore this issue and determine how
much staff time should be devoted to this.
Mr. Streckenbein commented that this would be a precedent setting discussion, and
that a lot more information would be needed to make any decisions.
Mr. Dor ill commented that staff will review our SFWMD permit and determine
how many of the private PB lakes are interconnected with the PB master drainage system.
This information will be provided at the next committee meeting for discussion.
STATUS OF OAKMONT LAKE 4-1 I2EMEDIATION PROJECT
Our ABB engineer, Mr. Jim Cann, reported that the survey for Oakmont Lake 4-1
has been completed. He provided the committee with segments of the survey on the display
screen for discussion.
Ms. Melanie Miller, Vice President, Finance Admin. at the Pelican Bay Foundation,
confirmed that the PBF is responsible for replacing the pathway along this lake as well as
updating/replacing landscaping along the lake. This PBF work will be coordinated with
PBSD staff, as part of the Lake 4-1 lake bank remediation project.
Ms. O'Brien suggested that we discuss our lake bank remediation plans with the
homeowners who live on the west side of Lake 4-1. Ms. McLaughlin suggested that we
meet with these homeowners after we have a more detailed plan. Mr. Weir commented
that the PBSD needs to make a decision on the appropriate remediation method based on
cost and longevity; this is not the homeowners' decision. Ms. McLaughlin added that
aesthetics should also be a consideration.
Mr. Carr commented that rip rap is a good solution for the remediation of the west
side of the lake, which would be 40% of the perimeter (the recommended maximum). He
provided two cost estimates for two suggested remediation options (provided in the agenda
packet) including: (1) Option 1: A combination of GeoWeb and rip rap estimated at $2.0
2
Pelican Bay Services Division Water Management Committee Meeting
February 1, 2021
million, and (2) Option 2: A combination of rip rap and re -grading estimated at SIA
million. Mr. Carr noted that he will be updating these estimates in the next few weeks,
based on the completed survey.
Mr. Carr commented that he will be testing the lake bottom material in the next few
weeks to determine whether it can be used for fill. Ms. McLaughlin expressed concerns
over whether copper would be stirred up and go into solution if the lake bottom material
were to be used for fill.
Mr. Carr commented that upon completion of the project, the 4 to I slope of the
lake banks will be restored. Mr. Dorrill commented that the goal of the project is to restore
the slope and holding capacity back to its original design. He also noted that the plan will
provide for the connection of two drain features per household.
Ms. O'Brien commented on the timeline, included in the agenda packet, which
shows November 2021 as the start of the construction of the project. She suggested that
this project start after the 2021/2022 winter season. Mr. Carr discouraged completing the
project in the wet season.
Mr. Dorrill commented that GeoWeb and rip rap projects require SFWMD permits,
while re -grading projects do not. Ms. O'Brien suggested that we consider a re -grading
project in order to save time and money.
After committee discussion, it was agreed that ABB would bring back updated cost
estimates of Options 1 and 2, as well as an Option 3, which would consist of re -grading the
entire perimeter. Mr. Carr suggested that the committee consider the longevity of Option
3. Mr. Dorrill suggested that Option 3 may also result in maintenance issues.
Mr. Dorrill commented that he would like to bring the planning phase of this project
to a conclusion. He suggested that the committee schedules a March meeting to review the
three cost options, and then bring a recommendation to the full board. Mr. Weir
commented that the decision on a remediation method will set the standard for future lake
bank projects.
CRITERIA USED TO PRIORITIZE LAKE BANK RESTORATION
Our ABB engineer, Mr. Tom Barber, provided an explanation and theory behind
his revised prioritization formula to be used to compile a ranking list of PB lakes for lake
bank restoration projects. He compared and contrasted this formula with his original
formula. The revised formula includes escarpment consideration, not slope. It also gives
more consideration to community exposure issues. Mr. Barber suggested that "risk of an
accident" should also be a strong consideration when ranking the lakes.
Ms. O'Brien commented that per our SFWMD permit, we are responsible for
maintaining the slope of the lake banks; other factors included in the revised formula are
not part of our responsibility.
Mr. Fogg commented that lake visibility should be a consideration.
Ms. Miller confirmed that the PBF recently had an engineer prepare a report on the
condition of the Community Center lake bank; she will provide a copy of the report to the
committee.
The committee had a discussion on the pros and cons of each of the two formulas.
Ms. O'Brien commented that the initial formula and ranking is more relatable to our permit
(quantitative), while the revised formula and ranking is more qualitative.

Pelican Bay Services Division Water Management Committee Meeting
February 1, 2021
Mr. Coleman commented that he would not be in favor of working off of both
ranking lists, which would only lead to confusion. He noted that the formulas were
developed to "take out opinions" when choosing the order of lake bank restoration projects.
Mr. Dorrill preferred that we stay with the revised formula and ranking list.
In conclusion, Mr. Fogg directed the committee to review the top five lakes on each
of the ranking lists, plus any additional staff recommendations at their next committee
meeting. Mr. Weir suggested that from this pool, the committee should select five or six
lakes for the next lake bank restoration projects over the next five years.
The meetine was adiourned at 10:47 a.m.
