Committee members had an issue with making that modification. Hearing none, Item D-
ii was thus moved up and joined with Item C-i.
VI. Public Input
INTEGRATED PEST MANAGEMENT SUB -COMMITTEE PAGE 2
MINUTES OF NOVEMBER 2, 2020 MEETING
Mr. Benton called on anyone from the public who would like to speak.
Dr. Robert Bedea, Roseland. He is very concerned that over the last couple of decades
the City has "dropped the ball" regarding management of the City's stormwater system.
He is also greatly concerned about any use, whether it be governmental or private
residents, of any product that is other than non -toxic and biodegradable.
Bob Stevens, 150 Concha Drive, Sebastian. Thanked the City for having this meeting.
He is pleased that the City is actually going to move forward with this plan. He stated that
there should not be any toxic chemicals used in the City's waterways. He reviewed how
the water in his neighborhood does not flow properly. He offered to volunteer to help with
this matter. He has a culvert next to his house that does not work because it is not
serviced regularly.
There being no one else in Chambers and no one on Zoom, Mr. Benton moved on to the
next Agenda item.
VII. New Business
A. Sub -Committee members to decide meeting schedule
Mr. Benton stated that staff's suggestion is that this Sub -Committee meet every other
week on Monday at 2.00 p.m. He inquired if any Sub -Committee members had an issue
with that schedule. Hearing none, he called for a Motion. A motion to have this Sub -
Committee's meetings held every other Monday at 2:00 p.m. was made by Ms. Callaghan,
seconded by Mr. Carrano, and passed unanimously via voice vote.
B. Scope of Stormwater IPM Plan
Introduction to the City's stormwater assets
Ms. Haigler made a PowerPoint presentation which identified and explained the
stormwater system in the City (SEE ATTACHED). She highlighted the challenges which
the City faces when managing the stormwater system. She then asked for
questions/comments from the Sub -Committee members.
Dr. Cox:
• Stated he very rarely sees the pumps running when he goes to the Stormwater
Park.
INTEGRATED PEST MANAGEMENT SUB -COMMITTEE PAGE 3
MINUTES OF NOVEMBER 2, 2020 MEETING
• Feels that the City is not claiming the credit it deserves for the Stormwater Park.
Mr. Griffin stated he will explore Dr. Cox's second concern. As far as the first point,
Dr. Cox is correct. The pumps will not be seen running because they have to be
run in the very early hours of the morning. The rate structure that is set up with
FPL is one that, if the pumps run anywhere near their peak periods of load, the
penalty is tremendous. If attention is not paid to the demand schedule that is set
by FPL, the City could see a bill of more than $2,000.00 a month. If it is paid
attention to, the City could see a bill of less than $100.00 a month. His department
works very hard to make sure the City's technician gets there very early and rigidly
adheres to that schedule.
• Considering the heavy rains that the City just had, he asked if it is likely that there
will be far more water going to the ponds. He considers it a wasted resource when
it is not used to its capacity. Mr. Griffin stated it is well used 12 months of the year.
It is a tremendous resource and is a real water -quality benefit. He will look into
what the City needs to do to make sure the City properly accounts for and claims
credit for that water -quality benefit.
There being no further questions/comments from the Sub -Committee members, Mr.
Benton called for public input on this agenda item.
Dr. Robert Bedea, Roseland. He stated that since he arrived in this area in late January
2019, he has been through the Stormwater Park and watched the property around the
area. He has never seen the pumps running. He is aware of the FPL schedule.
Bob Stevens, 150 Concha Drive, Sebastian He lives right across from the Park. He
has seen someone there a few times around 10-11 o'clock in the morning. Mr. Griffin
stated his department works very hard to keep the technician within the lower -cost
schedule. He emphasized that the schedule does vary and is not the same schedule
every month. Mr. Stevens stated the people want the water to be cleaned up, and the
money is not an issue.
Mr. Benton called for anyone else from the public who wished to speak on this item.
Seeing no one in Chambers and hearing no one on Zoom, he moved to the next Agenda
item.
C. Past Pest Management Activities
Best Management Practices (BMPs) and Mechanical Removal
Project
INTEGRATED PEST MANAGEMENT SUB -COMMITTEE PAGE 4
MINUTES OF NOVEMBER 2, 2020 MEETING
Ms. Haigler gave a PowerPoint presentation on this section, which covered an
explanation of what the Stormwater Department is doing. (SEE ATTACHED) She
described how the mechanical removal project was conducted.
Mr. Griffin added that his department started spending a tremendous amount of effort to
remove the vegetation that is mowed or cut from the canals, ditches, etc. He reviewed
that in past years his department has mowed and then very occasionally removed the
material. With the thought that all of that material that has been cut can wind up moving
through the stormwater system, moving into the canal, moving into the river, and
ultimately into the lagoon, it would be better if that vegetation could be removed soon
after it is cut. It is a massive job, and he is focusing on adding that to the mechanical
removal program. That protects the lagoon and protects the river.
Mr. Benton called for questions/comments from the Sub -Committee members on what
was just shown.
Dr. Cox:
• Repeated the question he had earlier as to whether the City is getting credit for all
the material that is cut and removed from the ditches. Mr. Griffin stated that is part
of the development of a stormwater master plan that the City is about to embark
upon. City Council has selected a consultant to do that. That will be one of the
elements that he wants to have in that plan, i.e. a reporting of and a plan for
reporting of the City's success in terms of moving forward and making progress in
removing nutrients from the system.
• Inquired as to where the material is removed and dumped. Mr. Griffin stated it
goes to the county landfill. Ms. Haigler added that she does the NPDES reporting,
and these projects are the kinds that are reported on the STAR report annually in
January. Stormwater Park is on the City's NPDES MS-4 permit.
• Stated that it was very instructive when he worked on the Parks and Properties
Integrated Pest Management Plan to have the Sub -Committee members be able
to do a couple of site visits to see what was happening, what the problems were
and what possible solutions there were. He suggested that this be done by this
Sub -Committee also so that they can understand the magnitude of the problem.
Mr. Benton stated that after this meeting staff will get together and will determine
some locations, and staff will work with the Sub -Committee and set some dates.
The staff will notice these dates publicly, and members of the public will be able to
attend as well.
INTEGRATED PEST MANAGEMENT SUB -COMMITTEE PAGE 5
MINUTES OF NOVEMBER 2, 2020 MEETING
Hearing nothing further from the Sub -Committee members, Mr. Benton called for public
input regarding the Best Management Practices or the Mechanical Removal Project
presentation that was just given.
Dr. Robert Bedea, Roseland. He is very much in favor of the mechanical approach. He
suggested that the City consider, rather than transferring this material, which is a valuable
Sebastian resource, out of town to the landfill, why not turn it into compost. There are
public and private lands, and this is a resource.
Joe Scozzari, Sebastian. He likes the idea of mechanical removal of the debris. He
thinks the City could make some money off of that as a nutrient. He also stated that much
focus is on the large swales and the big canals, etc. He has five lots in a row that are all
under water. He has complained several times. His rainwater tax went up $80.00 on
each lot. He opined that there are no strict directives on how the property owners are to
care for their swales and keep them clean. If someone from the City would come out and
give him his elevations, he will be happy to make it so that the water gets to the large
canals. He stated Hardee Park water body is completely clear. He thinks the problem
is getting the water out from the residential lots to flow where it is supposed to flow. He
has neighbors who have put sod over their swales, and so the water is damming up. Mr.
Griffin stated he will look at Mr. Scozzari's particular street. He stated that it is important
that everyone on the street not only maintains their swales but also maintains their
culverts.
Bob Stevens, Sebastian. Stated he was present when the team came to Hardee Park
for the mechanical removal. He suggested the employees who perform mechanical
removal could be managed better, as they spend a lot of time traveling back and forth to
the area where the material is dumped. Mr. Benton asked that there not be any finger
pointing to specific employees, etc. Mr. Griffin explained that the whole plan was laid out
with the contractor and, unfortunately, the contractor did some things they were not
supposed to do.
Mary Wolff, Sebastian. She spoke regarding swale maintenance. She suggested that
when new residents move into the City, they may not be aware that they are required to
maintain their swales. She recommended they have an education process on this
situation. She also opined that the age of many of the City's residents precludes them
from specifically going out and clearing their swales or culverts. She made the suggestion
that maybe the lawn maintenance companies could provide that as an additional service
for a small fee.
INTEGRATED PEST MANAGEMENT SUB -COMMITTEE PAGE 6
MINUTES OF NOVEMBER 2, 2020 MEETING
Jim Clifton, 817 Cain Street, Sebastian. He related that a few months ago someone
from the City came and attempted to clean out a ditch that runs down the side of his
property. He has obtained a copy of the drawing for that system which shows there is
more than enough grade that that ditch should be dry when it is not raining. There is
always water in it, which should not be if it were properly maintained. He does endorse
the idea of removing the vegetation that is cut. It serves no purpose except to fill up the
ditch faster than it would if it were removed. He is looking forward to progress being made
on these ditches. He stated that twice in the past few months his street had water over
the crown of the street.
Eugene Wolff, Sebastian. He has lived along Collier Creek for 23 years opposite the
Lake Hardee Park and is very familiar with that waterway. There has been a lot of
transformation over time. He was on City Council during the replacement of the sea walls
project, and he was intimately involved with engineering and the various aspects of that
project. He saw the mechanical harvesting. He opined that the clearing was heavily
taxed because of no spraying for almost nine months or so. By the time the mechanical
harvesting pilot project took place, the canal was in very bad shape. He was impressed
with how the machine worked. The machine itself was efficient, but he opined that the
rest of the project was not. A barge or platform of some sort is needed to dump the
collected material on so that there is not so much time invested in moving that material to
the dump site. He stated that once the system is gotten under control, and the harvesting
is done on a regular basis, it would be much cheaper and far more efficient. He suggested
that one thing that is overlooked when spraying is done is that all that material dies and
drops into the water creating dissolved oxygen problems, creating poor water quality
which affects the wading birds and the fish. He has seen a rebound in the wildlife
population in Collier Creek over time. He hopes that with this Sub -Committee, the City
will implement an IPM system that will balance the spraying and mechanical removal in
order to get the ecosystem back to where the residents would like to see it.
Mr. Benton called for comments from the Sub -Committee on the Best Management
Practices and the Mechanical Removal Projects. Hearing none, Mr. Benton moved to the
next agenda item.
ii. Applied Aquatics
Ms. Haigler stated that for years the City had a contract with Applied Aquatics, which is
the company that was contracted to spray pesticides on the aquatic vegetation. This was
a piggyback contract with FWS and the National Park Service, which meant that all the
terms of their contract with FWS and the National Park Service applied to the City's
contract. There were two years of treatment sheets. She has gone through all of those
INTEGRATED PEST MANAGEMENT SUB -COMMITTEE PAGE 7
MINUTES OF NOVEMBER 2, 2020 MEETING
sheets and logged all the data. She stated that some of the most frequently treated sites,
which are definitely areas that staff would focus on for IPM non -chemical projects, are
areas such as Schumann Lake, Hardee Park, and the Twin Ditches area. Some of the
most common plants that were treated were brush and grasses, which means emergent
shoreline vegetation. Next were algae, duckweed, and hyacinths. For fiscal year 2018
the City paid $24,000.00 for that contract with Applied Aquatics. Throughout that year,
the vegetation was controlled using 56.6 gallons of chemicals. Those were not just
pesticides, but also adjuvants, which is an additive to the pesticide which will help it with
dispersal to reduce drift, and surfactants to help it adhere to vegetation better. She stated
those chemicals will be discussed in depth at a future meeting. In fiscal year 2019, all the
chemicals in total were 85.7 gallons, and the cost of that contract was $26,000.00.
Mr. Benton reminded the Sub -Committee members that staff is providing this information
regarding past management activities, and Ms. Haigler can provide any further
information that any member(s) want regarding quantities that were used, etc. Mr. Benton
called for questions or comments from the Sub -Committee members.
Dr. Cox:
• Inquired whether that contract with Applied Aquatics is still in effect until the end of
this year. Ms. Haigler stated the City no longer has a contract with Applied
Aquatics.
• Recalled that at the City Council meeting addressing this situation, it was allowed
that the City Manager not only test WOW, but also use his own discretion to test
other products. He inquired whether this Sub -Committee will be discussing that at
meetings in the future. Ms. Haigler stated it is under Item D on tonight's agenda.
Hearing no further comments or questions from Sub -Committee members, including
those on Zoom, Mr. Benton opened the meeting to public comment, cautioning that such
comments should be limited to Applied Aquatics and the information that was just
provided.
Dr. Robert Bedea, Roseland. He is delighted to hear that Applied Aquatics will no longer
be spraying in the canals.
Eugene Wolff, Sebastian. He stated that he has held a pesticide license in the past. He
noted that the same sprayer was used for the last several years. He had spoken to this
sprayer once or twice. Mr. Wolff described how this sprayer was absolutely negligent in
performing his job. He further reviewed how the City created a mitigation area that
completely encircled Hardee Park and how the Applied Aquatics employee completely
INTEGRATED PEST MANAGEMENT SUB -COMMITTEE PAGE 8
MINUTES OF NOVEMBER 2, 2020 MEETING
destroyed that mitigation area with his spraying. Mr. Wolff suggested that, if the City
returns to using a spraying service, to not piggyback on the contract that Ms. Haigler
described. What is needed is someone who will work with the City to do the job properly.
Bob Stevens, Sebastian. He agreed with what Mr. Wolff said regarding Applied
Aquatics.
Seeing no one else from the public in Council Chambers, as well as hearing no one on
Zoom who wished to speak, Mr. Benton closed public input regarding this agenda item
and called on Sub -Committee members for questions or comments on this item.
Dr. Cox:
• Reinforced what Mr. Wolff had said. He further suggested that these sprayers
could not identify from the boat exactly what plants were to be eliminated. When
Dr. Cox asked the sprayer about his method of spraying, the employee stated that
he would be out of a job if Dr. Cox made any noise about the way he sprayed. So
Dr. Cox does not ever want to see Applied Aquatics performing this sort of work in
Sebastian. Mr. Griffin stated that Applied Aquatics are no longer working on the
east coast by their choice.
Hearing no further comments or questions from the Sub -Committee members, including
those on Zoom, Mr. Benton moved on to the next agenda item.
D. Current Status
Key pests
Ms. Haigler made a PowerPoint presentation on this item. (SEE ATTACHED) She
reviewed that this plan only addresses vegetation/plants and reviewed and described
what species are included and where they are found along and in the waterways.
Mr. Benton called for comments/questions from the Sub -Committee members on what
was covered by Ms. Haigler's presentation.
Mr. Carrano:
• Inquired whether any of the plants that live on the shoreline are protected under
the wetland regulations in Florida. Ms. Haigler said that is only along the lagoon.
INTEGRATED PEST MANAGEMENT SUB -COMMITTEE PAGE 9
MINUTES OF NOVEMBER 2, 2020 MEETING
The sea grapes and the mangroves can be protected along the beaches or along
the lagoon.
Dr. Cox:
• Stated it would be useful if all the Sub -Committee members could have a copy of
the book put out by the Aquatic Ecosystem Restoration Foundation, "Biology and
Control of Aquatic Plants, The Best Management Practices Handbook." Dr. Cox
stated that this book is being distributed by the people at IFAS. Ms. Haigler stated
she thinks she has the PDF.
Hearing nothing further from the Sub -Committee members, Mr. Benton opened the
meeting to public Input on the presentation that was just made regarding key pests.
Joe Scozzari, Sebastian. Asked why it would be desirable to get rid of some pests that
are native to Florida. Ms. Haigler stated that by definition a pest is anything that impedes
on the intended use of the space. In looking at stormwater, the main purpose is to
preserve the storage and the transport of the stormwater. If something creates a dense
monoculture and begins impeding the flow and storage, then it is a pest. That does not
mean it has to be eradicated, but it has to be controlled. It does not mean all the natives
have to die, but they need to be maintained at a point that they are not impeding the flow
and storage of the stormwater features. Mr. Scozzari suggested these native pests
should remain, as they may filter some things out of the water.
Dr. Robert Bedea, Roseland. He stated that plants are biofilters. We have a
responsibility for stewardship as humans. Mechanical harvesting is wonderful, but we
need to rethink what we call an invasive species and a problem. We do a knee-jerk
reaction using poorly defined terms, and we identify an enemy when it is really a friend.
Hearing no further comments or questions from the public in Chambers or from anyone
on Zoom, Mr. Benton moved on to the next agenda item.
iii. WOW use on aquatics
Ms. Haigler reviewed that City Council at a prior Council meeting approved the purchase
of WOW, which is a biopesticide, for use in the parks and also in stormwater to spot spray
around some of the City's weirs and dam features. Staff did test a small patch on
hyacinths, and it worked well. Duckweed was also sprayed in a patch, and staff is not
sure what happened, because there was heavy rain and the duckweed floated
downstream. It worked really well on cattails also. It did not work well on pepper. The
INTEGRATED PEST MANAGEMENT SUB -COMMITTEE PAGE 10
MINUTES OF NOVEMBER 2, 2020 MEETING
WOW was purchased to spot treat around the stormwater system, but none has been
applied at this point, as there needs to be someone licensed to apply it. Mr. Griffin has
just received that certification. Moving forward, it will be tested around some of the City's
main weirs and dams and other features. Staff definitely plans to include it in this IPM
Plan as well.
Mr. Griffin stated that staff will be conducting the tests that were directed by the City
Manager and discussed at the recent City Council meeting. It will be on the critical
structures in the canal, and more information will be collected on the use of this
peppermint oil natural herbicide.
Mr. Benton called for comments/questions from the Sub -Committee members on what
Ms. Haigler and Mr. Griffin just talked about.
Dr. Cox:
• The CEO of the company that produces this product, Eco-Mite, has told Dr. Cox
several times this product is only being tested for use on terrestrial environments
and habitats. The company has never promoted its use in aquatic environments,
but other people have. They do not know how effective it is. Dr. Cox cautioned
the City to be careful to not spend a lot of money on something that will not work.
Mr. Griffin stated there was a small amount of money spent on some additional
amounts. There have been very successful tests in the parks system with that
chemical, and the City Manager has discussed extensively the use of it in the
waterways as well. Mr. Benton stated he also has spoken to the owner/president
of Eco-Mite, and they are very interested to see the results of the City's use. Mr.
Benton stated staff has done a small test area for this product; however, the City
is not a testing agency, and the area that the test was done in is a very small area.
Staff would like to get more information by doing a little larger area. Spot spraying
is the plan and conducting the spraying in more controlled environments. Other
communities have also been testing it in the same environment, and it will be
interesting to see how the product works in the aquatic environment. On land, it
tested great. It exceeded what was being shown from glyphosate in the City's
testing area. It is a natural product. One of the main ingredients is peppermint oil,
but it is all natural. Dr. Cox stated care needs to be taken, because it has not been
tested with any results that can be looked at to know what effect it will have on all
other species that are in the area.
Mr. Carrano:
INTEGRATED PEST MANAGEMENT SUB -COMMITTEE PAGE 11
MINUTES OF NOVEMBER 2, 2020 MEETING
• The problem is that nothing shows the product's toxic impact to the environment.
There are lots of natural materials that are poisonous. We have no idea what this
product can do up the entire food chain. There is no way to test the impact to the
environment, either upstream or downstream. Ms. Haigler stated that is the
problem that is present with all biopesticides, because they are not EPA tested.
So the City would not make a plan that only had biopesticides, because they do
not require extensive research on how they affect specific communities and non -
targeted pests. Mr. Benton reviewed that it was part of the discussion in the Parks
Plan to include products that had been tested, and their effects are known. Mr.
Carrano stated that, again, the testing is looking at the efficacy --how well it works
in killing plants. Mr. Benton stated that the goal is to see the effects on the
environment in that controlled area. Mr. Carrano stated that the City does not have
the skills to see the impacts it has on an ecosystem. It would take tens of
thousands of dollars to look at the ecosystem before spraying application and
afterwards. Ms. Haigler stated that the goal of using it was never to broadcast
spray and treat all of the vegetation. It was only for spot spraying for emergency
protection.
Mr. Griffin stated that regarding the intensive effort that the City contracted for in the
Hardee Park area, he would like to get a little more perspective on that in terms of the
effort and the price and the final outcome. Mr. Benton stated the Sub -Committee will
address that when it gets to the mechanical portion of the plan. Today is just introducing
all of these items. Then the Sub -Committee will go into the biological aspect, and each
member will have a pest assigned to him/her. After that, mechanical, cultural, and
chemical aspects will be addressed.
Hearing nothing further from the Sub -Committee members, Mr. Benton opened the
meeting to Public Comment on the presentation that was just made regarding WOW use
on aquatics.
Mary Wolff, Sebastian. Regarding the overgrowth condition that is present in the City's
canals, she questioned whether it is known what nutrients are going into the canals, i.e.,
are they coming from people applying fertilizers onto their lawns. Is the goal to try to stop
people from fertilizing in the high rainfall periods? There are people moving into this
community continuously who are not aware of the special needs here. She also
suggested that a robust monitoring program is needed based on the time of the year.
She asked that, when the plan is implemented, it be complete.
Mr. Benton commented that this is the very first meeting for this Plan. If the IPM Plan for
the City's parks and properties is looked at, it will be seen that a lot of what Ms. Wolff
INTEGRATED PEST MANAGEMENT SUB -COMMITTEE PAGE 12
MINUTES OF NOVEMBER 2, 2020 MEETING
mentioned will be developed through this Plan. It will take some time, but the Sub -
Committee will take into account looking at what they have identified as key pests right
now, whether they will continue being pests in the future, and how all that information is
differentiated. As far as the public outreach portion, that is something that is being
emphasized with the City's new IPM website that was started with Parks and Properties.
The Natural Resources Board also has an objective with Sustainable Sebastian. So a lot
more of this information will be available via the website, Facebook, and other media.
Dr. Robert Bedea, Roseland. He suggested a new way of facing the problems that are
existing today, and that is, if we do not get to the cause of the problem, how are we ever
going to fix the problem. Rather than monitor a product that is meant for terrestrial uses
and put it in an aquatic environment, maybe it is a good idea, but likely it will be a waste
of time. When the outflow pipes that flow into the canal system are monitored, the
chemicals that are going into the system will be monitored. When we know what the
chemicals are, we can nip it in the bud.
Bob Stevens, Sebastian. He stated there have been many products that have been
tested that Applied Aquatics has used over the last 20 years. What has never been done
is that they have never been tested together. He gave an example of how he was affected
by being in the drift of what was being sprayed. He also mentioned that there is a permit
required to use these chemicals, and he suggested that that has not been happening. He
is glad to see that the matter is going to be addressed, as he feels it is very important.
He addressed a prior City Council meeting where the matter was addressed. Mr. Benton
suggested Mr. Stevens review the Minutes from that meeting.
Joe Scozzari, Sebastian. Thanked the Sub -Committee and staff for what they are doing.
Eugene Wolff, Sebastian. If access is needed to Collier Creek to do some tests, he
offered a vacant property that he owns that will allow access to do those tests.
Hearing no further comments or questions from the public in Chambers or anyone on
Zoom, Mr. Benton moved on to the next agenda item.
E. Biological Controls
Each member assigned one pest to research for the next meeting.
Ms. Haigler stated that at the next meeting the focus will be on non -chemical methods
and biological controls. More in-depth discussion will be held. She will begin with
INTEGRATED PEST MANAGEMENT SUB -COMMITTEE PAGE 13
MINUTES OF NOVEMBER 2, 2020 MEETING
assigning some of the primary pests to members to the Sub -Committee to do their own
research on them. She listed the pests assigned to each member:
Mr. Carrano -- hydrilla and hyacinth.
Dr. Cox -- shoreline grasses
Ms. Lovell -- algae
Mr. Stadelman -- giant Salvinia and spatterdock
Ms. Haigler stated she has provided each member with a folder containing information on
the different pests. At the next meeting, each member will give a short report on what
they found in their research for biological controls on those pests.
Hearing nothing further from the Sub -Committee members, Mr. Benton opened the
meeting to Public Comment on the pests that were just assigned to each member for
biological control of those pests. Seeing no one in Chambers and hearing from no one
on Zoom, Mr. Benton moved to the next item on the agenda.
VIII. Old Business -- None
IX. Sub -Committee Member Matters
Dr. Cox asked that the Sub -Committee define the problem(s), look at all the alternatives,
look at the pros and cons, look at what is best in terms of being better than doing nothing,
and make sure the public is involved.
X. Staff Matters
Ms. Haigler said that in the folder with the summary of the pests is a workbook on invasive
aquatic plants and their control. It is a really helpful introduction into what the Sub -
Committee is going to be working on. She also has folders for the members who are not
at this meeting.
Mr. Griffin wanted to give some additional perspective on the removal of vegetation from
the Hardee Park area via mechanical methods. The contractor did struggle. However,
the City paid a fair price for the work that was done. The City was protected because it
had a contract that was piggybacked on the St. John's Water Management District. The
contractor understood what the job was, and the contractor's job was to formulate a plan
to get that job done. The contractor was also educated in terms of what he could and
could not do in terms of disposal, because Hardee Park does have some areas where
some high -quality natural vegetation had been planted a number of years ago on the
INTEGRATED PEST MANAGEMENT SUB -COMMITTEE PAGE 14
MINUTES OF NOVEMBER 2, 2020 MEETING
shoreline. Staff did not want those plantings to be destroyed. The contractor was
required to come back because they had not completed the job. They had to spend
another 50% more manhours doing the work to complete the job as they were contracted
to do. The end result is that the job did get done for a fair price of $27,000.00. It was a
contract that had been advertised for bid by St. John's Water Management District. The
only downside to the project besides the cost to the City was that because they did not
follow through on the planning, this was not a profitable effort on the part of the contractor.
He wanted everyone to have that perspective, as a number of residents have watched
and observed and saw the before and after results.
Mr. Benton stated that, as the Sub -Committee is beginning to go through this Plan, it will
go step-by-step, similar to how it was done in the Parks and Properties Plan. He
appreciates all the public input, and staff will look into the issues that are being presented.

INTEGRATED PEST MANAGEMENT PLAN
I. INTRODUCTION
Scope
The City of Sebastian's stormwater conveyance system encompasses 9 miles of canals, 80
miles of ditches, and over 15 ponds and retention areas. Other stormwater assets include: 310
culvert pipes and catch basins, 7 baffle boxes, as well as countless swales, road crossing pipes,
dams, weirs, right-of-ways and a seawall perimeter. The Stormwater and Public Works
Departments are charged with maintaining all of these features so that the treatment,
transportation, and storage capacity of the entire conveyance system is preserved, while also
ensuring the safety of City staff, residents, structures, wildlife, and the surrounding natural
waters.
The City of Sebastian is bordered on the east by the Indian River Lagoon (IRL) and on the west
by the San Sebastian River (SSR). Both of these waterways are environmentally sensitive,
support a large number of native species, and are integral to the natural health of our region.
Therefore, the City must also serve as a steward to the IRL and SSR by ensuring that the
stormwater entering these waterways is as healthy as possible.
In order to best manage pests within the stormwater system, while also protecting
environmental health, City staff and contractors will continue utilizing the principles of
Integrated Pest Management (IPM) through the implementation of this IPM Plan. Please note
that this plan will not apply to any stormwater features located within any planned unit
development (PUD), as these subdivisions have direct contracts with the water management
district to design and maintain their own stormwater system. Also not covered by this plan is
the City's cemetery, parks, or other properties, as these features are managed collectively by
the City's Leisure Services Department and are addressed in a separate "Parks and Properties
IPM Plan," which was adopted by City Council on October 14'", 2020.
CITY OF SEBASTIAN PAGE 1
INTEGRATED PEST MANAGEMENT PLAN
IPM Sub -Committee
In October of 2020, the Stormwater IPM Sub -Committee was formed to assist City staff in the
development of an Integrated Pest Management Plan for the City of Sebastian's stormwater
conveyance system. The sub -committee is to be comprised of the Stormwater Director, IPM
Coordinator, three Natural Resource Board Members, and two local scientific consultants.
The role of the IPM Sub -Committee is to assist in the development of a cohesive IPM Plan,
advise on pest management issues, and evaluate the City's progress towards the goals of the
IPM Plan. The Sub -Committee will review and approve the annual IPM report before it is
presented to City Council. As part of the annual review, Sub -Committee Members will
evaluate the current techniques and products to ensure they are based on the best available
technologies and scientific information available. Recommendations will be made regarding
changes to the annual reporting process and the IPM Plan document.
In the development of the initial Stormwater IPM Plan, the IPM Sub -Committee will meet bi-
monthly. Following adoption of the final IPM Plan by City Council, the committee will meet
annually, unless more frequent meetings are needed, as determined by staff. All IPM Sub -
Committee meetings will be held in compliance with Florida's Sunshine Laws, with public
notice, posted agenda, and minutes taken by a recording secretary.
IPM Coordinator
In order to provide for the planning and oversight of the IPM program, the position of IPM
Coordinator is established. The appointed IPM Coordinator shall be a member of City staff
who is in a position related to environmental or planning, who shall coordinate with the
Stormwater Director. Together, they will lead the creation and implementation of the IPM Plan,
which will apply to the City's pest management activities on all of its stormwater ponds,
canals, and ditches. Their responsibilities will also include the following:
• Serve as liaison to IPM Sub -Committee
■ Monitor that City staff are adhering to the IPM Plan Standard Operating Procedures
■ Maintenance of accurate records on IPM implementation and use
■ Keep records of staff training in Green Business Best Management Practices and staff
pesticide applicator certification
■ Assure the inclusion of City IPM policies and practices in any applicable third party
contracts or purchase orders for pest management
■ Implement outreach efforts and maintain City's IPM Website.
The IPM Coordinator will prepare an annual report of the City's IPM activities, which will be
reviewed each March, by the IPM Sub -Committee and Stormwater Director in an effort to
assess the effectiveness of pest control methods, feasibility of new methods and technologies,
and decide whether revision of the IPM Plan is required.
CITY OF SEBASTIAN PAGE 3
INTEGRATED PEST MANAGEMENT PLAN
IPM Plan
A pest, by definition is any plant, animal, or pathogen which causes disease, inflicts damage,
or out -competes a more desirable species for an area. In addition, a pest may be
aesthetically undesired, or threaten to impact human/animal health. However, for the
purposes of this plan, noxious aquatic vegetation is the only pest of concern.
According to the 2011 Florida Aquatic Plant Management Act, the uncontrolled growth of this
vegetation poses a variety of environmental, health, safety, and economic problems
(Appendix B).This legislation charges the Florida Fish and Wildlife Conservation Commission
(FWC) with the supervision and control of aquatic plant management. Therefore, the FWC
establishes that a "noxious aquatic plant", is any part or whole of an aquatic plant which has
the potential to hinder the growth of beneficial plants, to interfere with irrigation or navigation,
or to adversely affect the public welfare or the natural resources of the state.
The Florida Aquatic Plant Management Act recommends that the management of these
aquatic plants be carried out primarily through "maintenance programs," as they achieve
more effective management at a lower overall cost.
The City adopts this IPM Plan as its aquatic vegetation maintenance program and adopts the
following definition of Integrated Pest Management as established by the City's IPM Sub -
Committee:
"To promote the most sustainable pest management methods, based on
planning and prevention; which aim to minimize risks to human and
environmental health through the limited use of chemicals, while also remaining
economically feasible."
Goals
■ Protect environmental resources by reducing the amount of pollutants entering surface
and ground water and minimizing effects on native plants, animals and habitats
■ Ensure effective, economic pest management within the City's stormwater
conveyance system, while minimizing health risks to the public, City staff, and the
environment
■ Promote the transparency of the City's pest management activities
■ Increase public awareness of IPM methods and benefits
IPM Program
IPM Policy. The Stormwater IPM plan, as well as future modifications or amendments will be
reviewed and voted on initially and annually by the IPM Sub -Committee, Natural Resources
Board, Planning & Zoning Commission, and then presented to City Council for final approval.
The plan will then be incorporated as City policy through the adoption of Resolution R-21-XX
by City Council (Appendix A).
CITY OF SEBASTIAN PAGE 4
INTEGRATED PEST MANAGEMENT PLAN
IPM Program Coordination. The Stormwater Director and the IPM Coordinator are responsible
for coordinating, tracking, and reporting the implementation of the City's IPM Program.
Tracking Pesticide Use. City Staff and Contractors conducting pest management activities
within the City's stormwater conveyance system are required to record thorough field data.
Accurate records will be maintained on pesticide use and non -chemical methods utilized that
are accessible for reference. All records will be retained for 1 year and stored on the City's
Laser fiche system per record retention schedule.
Staff Training. All City employees who, within the scope of their duties, apply or use pesticides
will be trained on the City's IPM Policies as well as proper chemical storage and use of
personal protective equipment (PPE). A certification course on Green Business Best
Management Practices will be provided through partnership with the University of Florida
Indian River County Extension Office as needed. The training sessions are coordinated by the
Human Resources Director, who will track employees' attendance and ensure that City field
staff holds an active certification.
Licensed Applicators. At all times a minimum of 1 member of City staff must be a state
certified aquatic pesticide applicator. The Human Resources Director and IPM Coordinator will
keep a copy of all staff certifications on file. All pesticide applications will be in compliance
with state regulations regarding applicator licensing.
Information Resources for Staff. The IPM coordinator will act as a resource for City staff to help
identify new pests and pest related concerns, and to assist in determining the best course of
action consistent with the established IPM SOPs. The IPM Coordinator will also seek out and
provide access to expert resources when needed.
Public Outreach. Education and outreach efforts will include distribution of information, either
created internally, or obtained through partnership with local and state government agencies.
The IPM Coordinator will coordinate and keep records of the following:
• A City webpage where the public may obtain information on IPM practices for their
property, view the City's IPM Plan, annual IPM reports, IPM Sub -Committee minutes,
and pest management treatment records.
• The City's efforts to promote the reduction of urban pesticide use through social
media, the City's website, print and television media.
• The City's outreach to pest control operators (PCO's) and landscapers.
• Distribution of IPM information and resources at public outreach and community
events.
• IPM information distributed to residents through the "New Homeowner Folders" during
the final planning and zoning inspection.
• Updates and status reports following the annual report and as requested by City
officials.
CITY OF SEBASTIAN PAGE 5
INTEGRATED PEST MANAGEMENT PLAN
Contract Provisions. The Procurement Coordinator will review contract provisions and/or
amendment(s) to agreements that provide pest management services within city maintained
ponds, canals and ditches covered under this IPM Plan. All such contractors shall be required
to review and sign the "contractor agreement" (Appendix B). Contract work will be
monitored to ensure that City IPM policies and practices are adhered to by all contractors
performing pest management work.
Regulatory Reporting. The IPM Coordinator will handle reporting to regulatory agencies, which
credit the adoption of an IPM Plan as a Best Management Practice (BMP).
• Incorporate the IPM Plan into the Florida Department of Environmental Protections
(FDEP)'s National Pollutant Discharge and Elimination System (NPDES) Phase II, MS4
Permit Cycle 4, Year 2 Annual Report (September, 2022) and the Cycle 5 NOI
(September, 2024) as a new BMP for Element 6: Pollution Prevention/ Good
Housekeeping.
• Add as new project and update through the statewide Basin Management Action Plan
(BMAP) annual report on water quality projects.
• Add as new activity and provide update to the Indian River Lagoon Council for the
Indian River Lagoon Comprehensive Conservation and Management Plan (CCMP)
annual report on lagoon -related accomplishments.
Community IPM Cycle
This established cycle (Figure 2) will serve as the guideline for IPM Plan development and is
based on planning and prevention, with the use of chemicals as the last resort for pest control.
1. Inspection and Monitoring: Staff routinely scouts the waters and surrounding landscapes
to locate pests. Pest populations are monitored by visual checks and traps.
2. Identification: Pests must be accurately identified. Life history attributes are to be known
for each pest identified. This step is key to effective treatment.
3. Planning: The focus is on prevention- what it takes to keep pests out. Determine what
action is needed and whether a threshold has been crossed. Proper techniques and
timing are for required management.
4. Implement Strategy: All pest management strategies are classified as biological,
cultural, mechanical, or chemical. All methods are combined to maintain pests at
acceptable thresholds.
• Bioloaical Control: enhances natural enemy populations by creating
habitat or adding populations
• Cultural Control: Disrupts the pest's environment by removing pest attractants
or utilizing pest resistant variety of desired species
• Mechanical: Creates physical barrier to pest entry
• Chemical Control: the last tool in the IPM toolbox, the goal is evaluate costs
and benefits to choose the least -toxic and most feasible option available
that will do the job
CITY OF SEBASTIAN PAGE 6
INTEGRATED PEST MANAGEMENT PLAN
5. Record Keeping: Accurate record keeping is essential to a successful IPM program. Data
must be kept on control methods implemented, chemical usage by staff, and purchase
orders. Determine if control methods were effective by knowing what has changed
through trap counts and observation.
6. Evaluate Effectiveness: Document if the program is meeting expectations. Establish if all
actions have been in compliance with the City's IPM Standard Operating Procedures
(SOPs). Assess what was learned and determine whether the plan needs revised.

INTEGRATED PEST MANAGEMENT PLAN
Standard Operating Procedures
When selecting and implementing a pest management strategy, from this plan, the following
will be considered by Citv Staff:
Site Factors. Use and function of the waters and surrounding landscape.
• Considering the use and function of the assets and the surrounding landscape,
stormwater features are divided into four functional categories (Figure 3) in which the
action threshold and methods are determined:
➢ Structures: including dams, weirs, spillways, catch basins, baffle boxes, culvert
pipes, inlets, outlets, and outfalls. These assets have a virtually zero tolerance for
pests, as they must stay clear of vegetation and debris at all times in order to
function.
➢ Canals: shoreline and seawall vegetation is acceptable and often encouraged.
However, vegetation must be controlled to the seawall perimeters so that the
storage and flow of the waterways is maintained.
➢ Ponds: shoreline emergent vegetation is encouraged. However, when the
vegetation is not maintained, it can quickly take over these assets, reducing
stormwater storage capacity and degrading habitat quality.
➢ Ditches: and right-of-way (ROW) areas have the highest tolerance threshold for
pests, maintenance required is minimal.
• Erosion and runoff potential of site
• Proximity to other surface, surficial, and groundwater resources

Health and Safety Concerns. Potential effects on City staff and residents.
• Toxicological properties and potential health effects of materials or methods
• Equipment operation safety issues
• Staff safety and injury concerns
Environmental Considerations. Protection of native plants, animals and pollinators.
• Consider toxicity or potential harm caused by the method to non -target organisms and
habitat.
• Potential for bioaccumulation of materials within soils and groundwater
• Know if there is potential for negative effects from any pest control method or lack
thereof on any federally or state protected species that may be in the area
• Be aware of any nesting birds in the area and potential affects the method may cause
• Understand the effects the method may have on pollinators
• The effects of reduced control of invasive plants or pests to native biodiversity
Product Characteristics. Specific product features
• Possible residual effect and decomposition products
• Volatility and flammability
• Product formulation, recommended dilution and package size
