SUB J: Mosquito Control within City Parks
On October 22, 2002, thc Park and Recre, afion Commission reviewed thc
city's existing policy concerning spraying for adult mosquitoes in city parks.
This review was ordered by thc City Council upon concluding a discussion on
mosquito control on September 23, 2002. This discussion was prompted by a
presentation made by Mr. Jim Stark, Public Information Manager for the
Metropolitan Mosquito Control District. Increased publicity concerning the
mosquito-borne disease La Crosse Encephalitis raised thc public's interest in
mosquito control this past summer.
BACKGROUND
On August 24, 1992 thc Chanhasson City Council approved the following
recommendation from thc Park and Recreation. Commission. regarding
mosquito control in city parks:
I. In regard to larval control briquettes, allow their use to continue
providing notification of treatment ai'eas and times are provided.
2. In regards to aduit, mosquito control chemicals (cold fogging), to
eliminate their use and to re-evaluate thc program in-the fall of 1993.
3. The practice of MMCD helicopters landing, taking off and loading in
city parks is prohibited.
4. That staff and thc city actively pursue other measures of controlling
mosquitoes, such as volunteer groups who are willing to remove
breeding site containers, possibly plugging tree cavities, and whatever
else can be done from a community standpoint to control mosquitoes
without chemicals.
A follow up discussion regarding tree hole mosquitoes (the lacrosse
encephalitis mosquito) resulted in allowing MMCD to test for thc "tree hole"
mosquito in city parks, ff populations warranted, the application of approved
treatment substances only will be allowed upon. thc city being notified, the
area for' treatment having been conspicuously posted 24 hours prior to
treatment, and that the Park and Recreation Director be contacted prior to
testing to allow for observation of the testing.

The review of the program in November of 1993 resulted in no changes to the
policies that had been established the previous year.
RECENT CORRESPONDENCE
Recent correspondence concerning the activities of the MMCD, in addition to
an e-mail from Mr. Rivkin is also attached.
STAFF COMIVIE~
Some conclusions I reached in 1992 concerning mosquito control have not
changed.
More mosquitoes live to carry out their life-cycle in the metropolitan
area than are ever killed by the MMCD on an annual basis.
Reducing the mosquito population by the number that the MMCD
does kill or prevent from hatching, reduces to some degree, the
likelihood that you will be annoyed or bitten by mosquitoes.
Given the infrequeney of chemical applications being made in the
early 1990's, banning their use in city parks seemed inconsequential.
,RECOMMENDATION
Spizale moved, Happe seconded that the Park and Recreation Commission
recommend that the City Council rescind the city's current policy and permit
control of adult mosquitoes in city parklands to resume. Also, direct staff to
take appropriate measures to notify the public through means available that
this program is re-instituting, when applications are going to take place,
information about how to be added to the notification list and where the
information's going to be posted. All voted in favor, except Atkins who
opposed, and the motion carried with a vote of 5 to 1.

Kelly moved, O'Shea seconded that the Park and Recreation Commission table action on

better quantify usage. All voted in favor and the motion carried nnanlmously. '
Franks: Todd, some marching, Todd and Jerry, some marching orders there.
Hoffman: We will also quantify the dollars, or the expenses...
Todd Hoffman explained to Ted Koltes the action taken by the Park and Recreation Commission.
REVIEW CITY POLICY CONCE~G SPRAYING FQR ADULT MOSQU1TOE~ IN
CITY PARK~.
Franks: I'm operating under the assumption that all of us have taken time to review the material
that's been presented to us. Todd, if you would take some time to hit the high points and then
we'll move forward.
Hoffman: I will hit the highlights and I am glad that I made the, what I consider to be the popular
recommendations on this item because I think it will go much more smoothly. Fa'St of all I'm
going to hand out something that I received in today's mail. It's the Metropolitan Mosquito
Control District 2001 Operating Review and Plans for 2002. The Mosquito Control District is a
special tax authority so you'll see that on your taxes. Just a side note. I saw them out checking
today for mosquitoes. I didn't 'know why but they were scooping and just to make sure they're all
dead. This issue, the file for this issue is about this thick. You would not have believed the
amount of public testimony that this body took, received back in 90, what were the years. 1991.
It turned into a debate over Mosquito Control District in public spaces. Not just mosquito control
in the'city of Chanhassen, and I won't go into that in entire detail but I'll just hit the highlights.
So the Mosquito Control. District was out here' on September 23~ to address the .City Council.
The minutes of that meeting are attached. The council, With good reason, is concerned about the
health concerns with the mosquito disease that we have now .on the topic of conversation on the
topic of conversation sO, the council as-ked the park commission to review the city's current
policy of not permitting the spraying of chemicals for adult mosquitoes in city parks. There is no
ban on spraying the briquettes or the corn cob granulars in these parks, and those briquettes or
granulars go in the wet areas and they change the chemistry of the larval mosquito and they never
hatch. Adult mosquitoes, or adultricide, this is where they go through with the logger. It was
quite popular I think, you know we all remember the, going through the neighborhoods with these
large loggers. They don't do that quite as much anymore, but they specially hit the times when
there are neighborhood, or community celebration. The.4~ of July or a county fair, those type of
things. In '91 we had a complaint where they sprayed for adult mosquitoes in Lake Ann Park.
They sprayed improperly. It left a residue. They sprayed too close to the lake, so there were two
things going on. They had a complaint that two residents became sick from the residue left from
the adult mosquito spray, and then the second one is that they sprayed illegally or not within the
label precautions of the chemical. So they were fined for that. They paid that. fine. Complied
with that and said they would not, they trained their applicators and they wouldn't do that any
longer. But then Mr. Rivkin convinced the commission and the council at that time that there was
some sense of health risk associated with the chemical itself and it's reaction it had on him and
his son, and that risk was greater than the risk of having'these adult mosquitoes being treated in
the parks. So then we have the resulting debate. What really stood out in that is that there was
,,'er3, few times, I think in the previous, I've got the statistic in here. They sprayed like 7 times,
and so the commission or the council said, so what's the big deal. We ban adult mosquito
control. They've only sprayed here 7 times in the last half a dozen years anyway. It's not going
:.

·
Park and Rec Commission - October 22, 2002
to be a big deal. So in '92 you have the action taken by the city council. Items 1 through 4.
larval control 'can remain. Adult mosquito control eliminate the air use and re-evaluate the
program. They shall not land or take their helicopters off at the parks. The staff actively pursue
other methods for controlling mosquitoes. Follow-up discussion was taken place and again no
changes made in the policies established the previous year. Had a recent correspondence
concerning the activities in addition to e-mails from Mr. Rivkin also attached, so here we are 10
years later. Mr. Rivkin continues to say that the Metropolitan Mosquito Control and mosquito
control in general is all evil. Mosquito Control says, in these times, especially with encephalitis
and the other things that these mosquitoes are threatening us with, that we should be doing more.
Staff comments. These are the conclusions I reached in '92 and they've not changed. And this is
just a common sense stuff. More mosquitoes live to carry out their life cycle in the metro area
than are ever killed by this mosquito control on an annual basis. We're talking a vast majority of
these mosquitoes live. They get around the briquettes. They get around the granulars. They get
around the adult fogging and they're out there looking for us. But reducing the mosquito
population by the number that the Metropolitan Mosquito Control District does kill, or prevents
matching, reduces to some degree, we don't know what that is. The likelihood that you will be
bitten by a mosquito. So you are doing some good. And then given the infrequency of the
chemical appellations made in the early 90's, banning their use seemed inconsequential.
However today, and this is based, this is where my recommendation comes frorm In :92 it
seemed reasonable to debate the effectiveness of spraying for adtfit mosquitoes, versus in the
public parks, but with the increased threat of the West Nile Virus and diseases that we have going
on, I'm recommending the commission recommend the City Council rescind the city's currant
policy and permit control for adult mosquitoes in city parklands to resume. With that motion I
guarantee that you will see an extraordinary amount of adult spraying in our parks next year
because Metropolitan Mosquito Control is going to want to come back into Chanhassen and give
us a presence again because they really felt kind of like the orphan child in Chanhassen. That not
very many people cut them out but Chanhassen, the Minnesota River Valley, National Wildlife
Refuge did. Hennepin Parks does not allow adult mosquito controlling, and just so you know
what their, those are hatural resource based organizations and their reason.for doing this is
because mosquito larva is the basis in the food chain for many living creatures so those
organizations say, yeah we understand the health risk, but we also, as a natural resource
organization, understand that we need to allow these life cycles to continue so they don't spray
for adults or allow the larval control to take place.
Franks: Thank you Todd. What I'd like to do is open this up for any quick questions that any of
the commissioners may have for Todd.
Spizale: One question. These two people the only people that have ever had problems?
Hoffman: That have come forward to the city, yeah. But there's tons of litanies of testimony
about the people that became ill from these chemicals.
Spizale: But these are the only problems we've ever had in our community?
Hoffman: Yes. That have been responded.
Spizale: In a period of how much time? Ever right?
Hoffman: Well for the past dozen years .... so you don't have any recent case studying. Prior to
that, these are the...I'm aware of.
26
Park and Rec Commission - October 22, 2002
Spizale: That's all I have.
Franks: Thanks. Commissioner Happe.
Happe: Has Mr. Rivkin stayed in touch with you on this Todd or?
Hoffman: Yeah, thus the recent e-mail that you have in your packet.
Happe: Yeah, that's what I was just n'ying. I thought I saw. I'I1 save my comments.
Franks: Okay, great. Well Amy, we'll move onto you.
O'Shea: I don't really have any.
Franks: Okay. Throughout that whole time since '91, they've continued with the briquettes,
correct7
Hoffman: Yes.
Franks: And how many areas, park areas have they treated with those briquettes? I know that
they do the wetlands out at Lake Susan.
Hoffman: I don't 'know for sure. They keep their own records. They do Rice Marsh Lake, Lake
Susan, there's a variety of areas that I don't have those. I don't have those numbers for you, for
those areas.
Franks: Now when I was reading the minutes of the park commission meeting, it appeared as if
· the spirit of their various motions on this issue was to have this, this mosquito control reviewed
on an annual basis. For sure in '93 it was to be reviewed, but there was some discussion that it
continue to come in for review, but it appeared that didn't happen. Do we happen to know what
the average portion of the allocation to the Mosquito Control District is from the average price
house in Carver County? Do we happen to know that? I know they talked about it back in the
old minutes what the cost was. We're still paying into the mosquito control.
Hoffman: Correct. Absolutely.
Happe: What?
Franks: We're all paying. Every house in Chanhassen, as a part of their .tax burden is funded for
mosquito control in Carver County which is including adulticide.
Hoffman: There was talk about in '91, there's no getting out of the program unless the entire
county.
Franks: Well it looks like it takes legislative action on the state level to get out of the program.
So we're locked into the program. So in a sense we've been, well that's comments so I'll move
on. Commissioner Kelly.
Kelly: I don't have. The only question I have is, I read in the, is it true that we are the only city
in the 7 county metro area? Okay. So from this comment in the minutes.
Park and Rec Commission - October 22, 2002
Hoffman: Is incorrect.
Kelly: Was incorrect. Alright.
Hoffman: Over stating.
Kelly: Okay.
Atkins: Does the adult mosquito control involve spraying?
Hoffman: Yes.
Atkins: And would this be for all the parks?
Hoffman: No. Traditionally this would go into the high use areas, Lake Ann, Bandimere, Lake
Susan, City Center, and then most communities, or many communities would call them and
schedule one for the day before the 4th of July. The day before the fireworks. Day before another
special event, so they come out. The Metropolitan Mosquito Control is an independent
governmental agency. They come out and they operate on. their own means and. by their own
methods,' and then we can influence them by giving a phone call and saying here's some dates
we'd like to see, and they typically try to accommodate you in those areas, and those requests.
Atkins: And your basic reason for wanting us to rescind this current policy is because of the
development of the West Nile Virus?
I-Ioffinan: And all the fears that go along with it.
Atkins: That's all.
Hoffman: Seeing that there's no other questions, let's bring this back to the commission for
comments. Since you just ended up Commissioner Atkins, we'll just start with you. '
Atkins: Oh I'm a big tree hugger and I really don't like spraying anything around so I'll have to
listen to some of your comments. I'm pretty opinionated about that.
Franks: Why don't you give us 5'our opinion. Let's hear it.
Atkins: Well I'm, chemical control of weeds even, anything pest control really rubs me the
wrong wa), so I have to hear more about this.
Franks: Okay. Tom.
Kelly: I think for me at least West Nile hit home when I heard about the person in Chaska being
diagnosed this summer with having West Nile, so it was no longer a Louisiana or Alabama issue
where it first came up and it has now come up north here and so I think I'm in favor of adult
spraying just for the fear of, of not eradicating West Nile but maybe limiting it's spread and the
spread of other diseases that those little mosquitoes carry. That's it.
Franks: There's some things that I found interesting in the park commission minutes from July
28, 1992. One is that there's a quote by, it's Harold Trende I think is talking, and suggesting that
allergists stated that people allergic to ragweed could'eXhibit cross sensitizatib/i,~ould exacerbate
28
Park and Rec Commission - October 22, 2002
· . ~.~..~
·
respiratory diseases like astluna. It's very interesting that my son, who is allergic to ragweed, and
has asthma, reacts when they aerial drop the granules for the...and so I happen to be in a family
where we're directly affected by these chemicals that are dropped into our city. What we do is
we're on a notification list that when they are coming by to do their applications we stay inside.
And that has been perfectly satisfactory once we figured out what was going on, and it's cemdnly
my opinion that the risks of some of these mosquito borne illn '.e~ses are far more danffewus than
telling my son that we need to slay inside for an afternoon. And ~o whereas in 1991-92-93 when
they were not looking in the face of the spread of some of ~ diseases, you know it's probably
prudent for them to lake that course of action. I think times have changed now. The situation is
altered to the point where as long as application is done per hbel and according to the protocol of
their agency, which is something I think as a city we, staff needs to keep a close eye on, that it
seems like a good idea to do it since we're paying for it anyway. And I've heard a lot of
comments about mosquitoes at the 4~' of 1uly celebration actually being an incredible nuisance.
So since we're paying for that celebration as well, I think that we should do what we can to make
our parks as enjoyable as possible. Commissioner O'Shea.
O'Shea: My comment would be, I think perception rules and with the threat of West Nile Virus
being so close, that the perception would be negative if someone contracted West Nile Virus and
knew that we were not doing something as a city to prevent it. Again I know you don't know
where you catch it, but I think if there was an outbreak in Chanhassen I'd feel better knowing that
the city did as much as they could to prevent it from happening at least in our city' parks. So I do,
and again with Chair Franks comment, I agree. Notification'needs to be carried out successfully
to people that do have, that do react to it or want to stay away from it because they fear the
chemical. But I do think it needs to be brought back in.
Franks: Thank you. Dave.
Happe: I agree with Commissioner O'Shea. In reading through the notes from the past
commissions that dealt with this, it was requested but actually declined that it become a
permanent ban. That was supposed to be reviewed on an annual basis. Unfortunately Mr. Rivkin
at the time had a serious medical problem, but that medical problem it seems was caused by an
improper application of the chemicals at .that time. There have been other cities that had a similar
ban and my understanding is, at least in some of those cases that similar bans have been rescinded
and I agree with Chairman Franks. Our taxpayers are paying for this service and I will be in
support of spraying for mosquitoes.
Spizale: And I would also be in support of spray because I think we can all enjoy our parks a
little bit more knowing that it's just a little bit safer out there so I would agree.
Happe: Chair Fran 'ks, I'd also just mention that the only information that I have was based on my
reading of this packet. I did try to contact Mr. Rivkin. He wasn't available for a conversation
prior to this so.
Franks: Appreciate that effort. I also made some, indicate efforts this morning to actually speak
with some agents in the mosquito control district and of course they took the opporttmity to lobby
about re-instituting their services to the city of Chanhassen quite strongly, and I found them to be
fairly persuasive so. Jack, anything?
Spizale: No.
Park and Rec Commission - October 22, 2002
Franks: Before we wrap up I just found it.interesting in the park commission minutes from 1992
again that the comments of Al Klingelhutz beginning on page 5, and indicating that he loves to
garden and you can see by the color of his skin that he's out in the sun a lot and then him stating
that he hasn't aged. And I remember when there was mosquito control in this area and at times
we've had rains and moisture, these mosquitoes would almost pick you up and carry you away,
and that was 1992 and I'll tell you in my back yard, and I'm one who loves to garden and I'm
going to say I don't think I've aged either. That the mosquitoes.almost picked us up and carded
us away this year. It was just incredible and anything that we can do for Al and I...maybe it's
those same mosquitoes hanging around.
Happe: Whoever does offer a motion on this, it'd be great if they could include a strong
recommendation from the Park and Rec Commission that there be a particular emphasis placed,
as Amy said, on the notification piece of it. We want to make sure that we, if we do re-instate the
spraying, that we spread the word as loud and wide as we can just to make sure that everybody
understands this change in policy.
Hoffman: We're going to do some press release through the newspaper. That's, right there
they'll post it at the entrance to the park but if you want to be on a call list, then you need to
contact and they'll put })ou on a call list.
Franks: You need to contact them. The other thing Todd, since there's been so much time since
we've actually had this, we may need to go a little bit more out of our way to inform.the public
that this is starting up again. This is-how you get on the call list. This is what's going on, and
especially during those times when we might be making a request as a city for special
applications in high use areas for certain events. Tournaments, 4m of July, that kind of thing,
since we'll be making that request ahead of time. That we actually find some way to publish
ahead of time that that will be occurring.
Hoffman: We can do that through the newsletter. Web page.
Franks: Through the newsletter and web page. And through the press release, inform people that
that will be posted on the web page. Is there a motion? Don't be shy. It's right here.
Spizale: I'll make a motion. I make a motion that we recommend that the City Council rescind
the city's current policy and permit control for adult mosquitoes in city parklands to resume. And
to that I will add, maybe we should come up with some type of a better, how should I say?
Letting people know when the park's going to be sprayed...my motion.
Franks: So are you suggesting that the staff then take appropriate measures to notify through
means available that this program is re-instituting and also in addition, when applications are
going to take place?
Spizale: Yes.
Franks: And along with that information about how to be added to the notification list. And
where the information' s going to be posted. Does that clarify your notification?
Spizale: I think that's perfect.
Franks: Alright. Is there a second to that motion?
30
Park and Rec Commission - October 22, 2002
Happe: Second.
Franks: The motion's been moved and seconded.
Spizale moved, Happe seconded that the Park and Recreation Commission re~mmend that
the City Council rescind the city's current policy and perml, t imntrol of adult mosquitoes in
city parklands to resume. Also, direct staff to take appropriate measures to notify the
public through means available that this program is re-instituting, when applications are
going to take place, information about how to be added to the notification list and where the
information's going to be posted. All voted in favor, except Atkins who opposed, and the
motion carried with a vote of 5 to 1.
Franks: What I'd like to do then is correct the record that Commissioner Atkins has. voted in the
negative on the motion and would you like to state your reasons for doing that, if you choose.
Atkins: No thank you.
Franks: Okay. The motion carries.
RECREATION PROGRAM REPORTS:
2002 HALLOWEEN PARTY.
Franks: Jerry, are you filling in for Corey?
Ruegemer: I will.
Franks: Alright. Well we'd like you to do that.
Hoffman: He represents him at time. C0rey doesn't purposely not show up here, but he's not
assigned to this meeting so Mr. Ruegemer represents Covey here..
Ruegemer: I am his voice.
Franks: Well you can let Covey know sometime that we certainly WoUldn't mind seeing him here
at our meetings, when he has the time to show up for us.
Ruegemer: I'm sure he would enjoy seeing all of you.. Just to give you a real quick verbal update
on the Halloween party. We did re-nm the flyers, since we had talked last time. They had been
distributed to the schools. We purchased candy last weelc Everything is, not a whole lot of hard
candy Rod. Thank you. We have a lot of the key club members, about 30 people helping out
with various games and hay fides and a lot of that sort of thing but just wanted to' offer up the
volunteer list again. We've still looking for some costume characters in the kind of friendly
hallway so to speak, and don't worry about a costume. We have plenty of costmn~ to go around
so if anybody's interested in that. Volunteers will need to be there around 4:45 at the Chart Rec
Center, and we will provide food for you in the form of pizza, sandwiches, something like that to
be determined so, just wanted to let everybody know kind of where we were on that event.' I'll
pass around the sheet. I know we had talked about this last time and if anything has changed in
)'our schedules and you'd like to put your name on the list to join the festivities, we certainly
would appreciate that so I will pass the list. Dave looks eager.
Park and Rec Commission - October 22, 2002
Franks: It's a fun time.
O'Shea: Jerry, would you, if you need to move me, I'm on there.
Ruegemer: ...and you can certainly hold onto that volunteer list until after the meeting if you'd
like to. Does anybody have any questions on that? I just want to give everyone kind of a brief
update as to where we were at this point.
Franks: And you're moving Half Pint and Oscar to the back...
Ruegemer: We are moving further and further away from that bleacher area.
Franks: And you are set using cones and tape or something to create a safety area.
Ruegemer: A safe zone if you will.
Franks: Alright. Or something.
Ruegemer: Any other questions?
Franks: Are you having the costume characters on boih sides of the center hallway?
Ruegemer: What would you like to see Rod?
Franks: Well it does create some congestion actually. If the costume characters it might, well
you might want to take a look and a have a contingency plan.
Ruegemer: Our nmnbers are down a bit but we certainly can have a plan B and C.
Atkins: Can I wear my own costume?
Ruegemer: Certainly.
Franks: Oh absolutely.
Atkins: It's not scary but it's cool.
Franks: Great. And how many hay wagons?
Ruegemer: Two.
Franks: Two, good. And out the back door?
Ruegemer: Yeah, go out that north door.
Franks: And is there someone assigned for crowd control?
Ruegemer: We're going to have Boy Scouts.
Hoffinan: And some adults.

MEMORANDUM
TO: Park and Recreation Commission.
FROM: Todd Hoffman, Park and Recreation Director
DATE: October 4, 2002
SUBJECT:
Review City Policy Concerning Spraying for Adult
Mosquito's in City Parks
On September 23, 2002, Mr. Jim Stark, Public Information Manager for the
Metropolitan Mosquito Control District (MMCD), addressed the City Council.
The minutes from that presentation are attached. Upon conclusion of
discussion that evening, the City Council asked that the Park and Recreation
Commission to review the city's current policy of not permitting the spraying
of chemicals for adult mosquito control in city parks. The file from 1991/92
concerning this topic is quite extensive. To assist the Commission in your
review, I will break the process down into manageable sections.
TItE COMPLAINT AGAINST SPRAYING FOR ADULT
MOSQUITO'S (1991)
Mr.. Eric Rivkin, a Chanhassen resident complains that he and his son became
ill frorfl co.ming in contact with chemicals intended for adult mosquito control.
Mr. Rivkin filed a complaint with the State Department of Agriculture
alleging improper use of pesticides by the Metropolitan Mosquito Control
District. The district acknowledges its wrongdoing and pays-a $1,000.00 fine.
THE RESULTING PUBLIC DEBATE OVER THE SAFETY AND
EFFECTIVENESS OF MOSQUITO CONTROL
As a result of this claim a yearlong debate over the safety and effectiveness of
spraying for adult mosquitoes in city parklands is launched. The actual
number of applications of these so-called "adultricides" ih city parks is
discovered to be relatively few. It becomes apparent that What is at stake for
both the MMCD and the complainant is much more than just the spraying of
mosquitoes in the Chanhassen park system. The MMCD retains specialists
from across the country to attend a Chanhassen Park and Recreation
Commission meeting in their defense. Mr. Rivkin continues to submit
documents calling into question the safety and effectiveness of the mosquito
control program.
Park and Recreation Commission

ACTION TAKEN BY CITY IN 1992
On August 24, 1992 the Chanhassen City Council approved the following
recommendation from the Park and Recreation Commission regarding
mosquito control in city parks:
1. In regard to larval control briquettes, allow their use to continue
providing notification of treatment areas and times are provided.
2. In regards to adult mosquito control chemicals (cold fogging), to
eliminate their use and to re-evaluate the program in the fall of 1993.
3. The practice of MMCD helicopters landing, taking off and loading in
city parks is prohibited.
4. That staff and the city actively pursue other measures of controlling
mosquitoes, such as volunteer groups who are willing to remove
breeding site containers, possibly plugging tree cavities, and whatever
else can be done from a community standpoint to control mosquitoes
without chemicals.
A follow up discussion regarding tree hole mosquito's (the lacrosse
encephalitis mosquito) resulted in allowing MMCD to test for the "tree hole"
mosquito in city parks. If populations warranted, the application of approved
treatment substances only will be allowed upon the city being notified, the
area for treatment having been conspicuously posted 24 hours prior to
treatment, and that the Park and Recreation Director be contacted prior, to
testing to allow for observation Of the testing.
The reviexv of the program in November of 1993 resulted in no changes to the
policies that had becn established the previous year.
RECENT CORRESPONDENCE
Recent correspondence concerning the activities of thc IvhMCD, in addition to
an e-mail from Mr. Rivkin is also attached.
STAFF COMMENTS
Some conclusions I reached in 1992 concerning mosquito control have not
changed.
More mosquitoes live to carry out their life-cycle in the metropolitan
area than are ever killed by the MMCD on an annual basis
Reducing the mosquito population by the number that the MMCD
does kill or prevent from hatching, reduces to some degree, the
likelihood that you will be annoyed or bitten by mosquitoes

Given the infrequeney of chemical applications being made in the
early 1990's, banning their use in city parks seemed inconsequential.
RECOMMEDATION
In 1992 it was reasonable to debate the effectiveness and safety of spraying
for adult mosquito control in public parks. With the apparent increased threat
of the West Nile Virus, I am recommending that the Commission recommend
that the City Council rescind the city's current policy and permit control for
adult mosquitoes in city parklands to resume.

we acquired such a significant reduction?
Sgt. Dave Potts: That's something that I would probably have to look into and get back to you on
that. Not a number that jumped out at me when, when I read through these monthly deals, I don't
necessarily go through every item so if you have a question like that, I'd certainly take a look into
it_
Councihnan Ayottc: !'11 just send an e-mail but the other comment is generally speaking, 2002
events are goi,~g down. I mcan thc trend is in fact a positive'trend so tlmt shows some good
things.
Sgt. Dave Ports: Well we like to sec positive trends in our figures. Sometimes we don't have thc
control over lh~m. you know we're reactionary to a large degree but.
Councihnan Ayotte: Thank you.

VlSI'rOI{ I)RESENTATIONS: I)RESENTATION ON 51ETROPOLITAN MOSQUITO
CONTROl. DISTRICT SERVICES. JIM STARK. PUBLIC INFOR,~IATION ..XlANAGER.
.~lay~.~r J:msen: We have a scheduled presentalion from the Mclropolitan Mosqtfito Co,ltr~i
l}istrict Sen'ices. Jim Stark. Appreciate your joining t,s this evening. This is:one of those hot
issues in tile cotmtt3' these days.
.lira Stark: Thank yot, Nladam Mayor and council members. I didn't prepare a formal
prescntatio,~ so l think what I'll do is just give you a brief history of what the organizalion does.
What we do in thc City ol'Chm,ha.,c~cn and then open it t,p for any questions you might have. The
Nletropolita,1 Mosqt, ito Control District was'formed in ! 958 under State Statutes. We're a
mosquito abatement district that controls mosquitoes, biting gnats and monitors thc distribution of
lyme disease ticks in the metropolitan area. We're actually a function of county government.
We're governed by a board of 17 county commissioners. Commissioner Ishe is the
Commissioner that sits on our board from Carver Cou.hty, and they direct our budget and our
activities during the year. Our budget in 2001 was about $9.6 million dollars. It's a lot of money.
but the area that we control mosquitoes in is very large. We control mosquitoes in an area of
2,600 square miles in the counties of Anoka, Ramsey, Hennepin, Washington, Dakota, Scott and
the eastern !/3 of Carver County, so it's a pretty big job. We're primarily a regional larval
control program, meaning we target immature mosquitoes while they're developing in the water.
About 85 percent of our resources go towards trying to keep mosquitoes from hatching into adults
and flying off in 50,000 different directions. Protection of public health is another important
component of tile program. We control mosquitoes that transmit Lacrosse Encephalitis and then
certainly this )'ear one of the big issues is West Nile Virus. It's a viral disease that's transmitted
by mosquitoes. We're really not quite sure which mosquitoes yet in Minnesota. Primarily what
City Council Meeting - September 23, 2002
we've done tlais summer is we have sampled in areas where we found positive bird reportings.
We've had a lot of birds reported dead who have tested positive for West Nile Virus. We've had
a number of horses in the metropolitan area that have tested positive for West Nile Virus and
unfortunately we've had a few human cases of West Nile Virus. We've gone into those areas,
collected a lot of the adult mosquitoes and sent them to the Minnesota Department of H~alth. We
haven't identified any positive mosquitoes yet, but hopefully here in the next month or so the
Department of Health will be able to look at a lot of those mosquitoes and tell us which species of
mosquitoes is transmitting West Nile Virus, to go a long way towards managing those mosquito
numbers. Back to the program, as I say we're primarily a larval control program but we also do
adult mosquito control to reduce disease threats, but also in response to rcquests from
communitics for civic events. Wc'l] also rcspond to ncighbofl~oods who identify heavy
infcslafions of mosquitoes that arc kind of intcrfering with thcff outdoor activity. So I think, thc
history with Chanhasscn is back in thc carly[ 990's thc city council askcd our abatement district
to stop doing any adult control of mosquitocs in thc parks in thc city of Chanhassen. and I don't
know ifyou're thinking ofrcconsidcring that but I'm hcrc tO ccrtainly answer :my qucslions
about any aspects of thc program and I'll open up to any questions.
Mayor J:mscn: Oka.v. lhallk yeti. I'nl jtlsl curious. Other commun,tics like our's, do fi~cy have
similar policy, in place where y, ou'r¢ not spraying in their parks or typically are you in the
community parks.
.lira Stark: Well thc only other community' that had asked us not to do adult control within thc
property management was klaplcwood and they rescinded that request about 3 or 4 years ago so
right now thc City of Chanhasscl~ is thc only city within thc 7 COtlllty moire district that's asked
t~s Dot to do control in thc property iJlcv manage. Adult mosquito control. We continue to do
larval mosquilo control on thc property, that thc City ofChanhasscn mnn'~,,cs,= .. but we've riel dollC
:idllJi mosquito control.
hi:tx'or .l:ms,.:n: \Veil apparcr~lly tiao original rcsolt~tion was in reaction and response lo some of
otn' residents, in Pact ! guess reacting and getting iii from thc spray. Do you have incidents like
that? Is there an adverse affect il'someone is in co~ltact with that spraying':
Jim Stark: Tiaa klinnesola Department of Health did a risk assessment oil thc two aduh control
'materials that we usc and found that minor exposure to the control material shouldn't pose a risk
lO I'lt[ITl:ll'~ health. Also the legislative auditor. [l~e Minnesota Legislative Auditor did a complete
kind of scientific review of om program back in 1998. Their findings were consistent with thc
\Vorld Health Organization and EPA that the control materials used by thc district, if they're used
according to label, don't pose a significant risk to either humans or the environment so. xx'e have n
few calls from pcoplc who arc maybc hypcr sensitive and wc try to address those issues by
notif'y'ing pcople. We have a notification list that if people ask us to be on thc notification list,
we're happy to abide by that. We put any place that we're going to do adult mosquito control on
any given day during the summer, on an information linc. A phone line. Same information is on
thc web page. We havc a web site that we maintain so. We havc expanded our notification
efforts in thc last few years to try to, at least allow people who have concerns about the adult
control, or any part of our program, access to thc infon~ation about where a schcduicd spraying's
going to happcn so. So I guess in dircct answer to your question, thesc materials have very low
mammalian toxicity, and we do not get many calls from folks that have issues with health issues
with thc con~rol matcrials.
klayor Jansen: Okay. thank you. Any other questions council for Mr. Stark?
City Council Meeting - September 23, 2002
Councilman Ayotte: We have ! 1 lakes. A lot of wetlands. And thc densest population in
Carver County. In your view are wc being remiss by not allowing you in to take care of business.
especially in light of the Nile Virus issue.'?
Jim Stark: Well remiss is a pretty.
Councilman Ayottc: Not to put you on the spot.
Jim Stark: Well. and that's why I'm here. You know I work for a mosquito abatement agency,
one of 800 that operate throughout the United States, and most populated areas have formalized
mosquito control and one of the responses to these disease issues is adult mosquito control. We
try to be proactive and try to do the larval control and try to, with Lacrosse Encephalitis, clean up
tile artificial containers and tires and fill in tree holes where these mosquitoes develop. But when
there arc mosquitoes out there flying around actively transmitting the virus, one of'our key
components to control those mosquitoes is adult mosquito control so in my personal opinion
certainly monitoring mosquitoes within 5'our park systems, and then treating mosquito species
that might be vectors of those diseases is certainly a prudent thing to do so I certainly would
support that.
Mayor .lanson: Were you to be spraying in our parks, how frequent a basis would that be in a
S1.1111111C1'?
.lira Stark: Kind of depends on mosquito populations. \Vc work off of threshold levels. Wc have
thresholds for certain species of mosquitoes and when adult mosquito numbers exceed those
thresholds, that indicates that there is an opportunity to spray those mosquitoes. It doesn't
necessarily mean that it's always going to happen. A lot ortimes we are. as I sa5'. we rely mainly
on larval mosquito control. Adult mosquito control is just kind of an approach we'll use in case
we miss some mosquito species or we have a vector mosquitoes in certain areas. So it'just
depends on thc levels of mosquitoes throughout the summer, and the types of mosquitoes you
h~,ve in tile p:,rks.
.'Xlavor.lan,¢en: So an on need basis is whal i'm hearin,, you say.
Jim Stark: Yeah. and there are a mm~ber o1' communities thai we will monitor th'dr heavily used
parks on a regular basis and we may spray them fairly routinely, maybe 3 or 4 times during thc
summer, but there are some other parks where we may only spray them when thc city calls us and
says hey. we're going to have a softball tournament or we're having some kind ofcvent in that
area. And certainly we could work with the city on how you want !o manage certain parks.
Mayor Jansen: Okay. Councih'nan Labatt'?
Councilman Labatt: Well you kind of answered it right there. If you could .maybe just kind of a
little bit more indepth on what is thc adult abatement process that you usc. Is that like you know
from when I was a kid in Minnetonka growing up. it was the pick-up truck driving through with a
big logger emitting a plume of fog.
Jim Stark: We still do that. We do adult mosquito control m'o different ways. One is with a
backpack sprayer. It's what we call a barrier treatment, where we spray the synthetic pyretheroid
material onto vegetation where mosquitoes harbor or rest during the daytime. Larger particles,
£airly specific area that's treated. Mosquitoes come in there and come in contact with material
and lhat's how lhey're controlled. The other way we do mosquito control is in the evening with a
City Council Meeting -- September 23.2002
truck mounted logger. A lot of smaller littlc particles suspended in the air. When the mosquitoes
fly through that mist, a very small portion of that mist is actually the insecticide but when they
coinc in contact with the insecticide, that's how they're controlled.
Councilman Labatt: So this would be confined.just to the city parks. I mcan we have trails that
kind of have casements or cross access easements through property. Or skirting the shoulder ora
road. Would you be also driving down those too?
Jim Stark: Well we do adult mosquito control on private property throughout the metropolitan
area. People have the right under State Statutes to ask us not to do that. Any control on their
properties and we certainly abide by that request but our services have been in fairly significant
dcmahd here in the last couple summers. We've had some fairly'healthy adult mosquito
populations and we've had these disease issues so the vast majority of calls we get, this year well
over 5.000. have been from people who are asking us to come out and either check little wetland
on their property or to address adult mosquitoes that they're dealing with in their back yard so.
Councilman Labatt: How many calls have you goli¢l~ i~ot IO spray?
Jim Stark: Oh. we usually get about a handful ti year. So it's fairly ,ninor compared...
Mayor Jansen: Not to i')Ul you on the spot but are you aware of the number ofcalls you've gotten
froln Chanhassen this year to come out onto i')rivate property to spray? Or to check.
.lira Stark: You know I can't. I'd have to look at our data base. l'know there have been a
number o1' calls I¥om Carver County. I would just have lo look and sec which ones came fi'om
C'hanhasscn or other areas. Oilc o['lhc West Nile Virus cases was in Chaska. mid I klloW lllicl'
that we got a significant numl3cr ofcalls fi'om thc Chaska area to come tun and do adult mosquito
c'OIi[l't~]. J c]Oll't klloW Jlow Ill[lilY oJ'IJlos¢ WOI'C fi'Oil] CJmnJlaSScn.
Max or .lanson: Okay. Because at this i')oint what wc would be having a conversation around
would be tile city parks, just so u.'¢'re clear. Tha['s the only i')rol')¢rly right now tha't they're
restricted fi'om coming in and actually spraying, according to this resolution ihat we have. Any
other questions or co;nn'~enls for Nit. Stark?
C'ounciim.'m Ayott¢: ilavc you g~.l a card with your e-mail addrcs.., for tls or do you have
something that we can?
.lira Stark' Yeah. it's out in thc cai'. I'll bring it I,ack ill.
Nlay'or Jansen: .\Ir. Gerhardt. anything to add'.)
Todd Gerhardt' Yeah. Jim. do you have a public access video that you share with communities
about mosquito control?
Jim Stark: You know we have one but it's kind of outdated. We kind of turned over that
program into a power point presentation. We're talking about re-creating that video but I
certainly can look into something that you might be able to run on public access if we redo it.
Todd Gerhardt: Okay. That'd be great.
Mayor Jansen' Well we appreciate your coming and sharing that information with us this
evening so that we can maybe better make a decision as to what to do with our city parks.

Jim Stark: Okay.
Mayor Jansen: Thank you very much.
Jim Stark: Thank you.
Todd Gerhardt: Mayor. Council members. If you'd like, I would suggest that the Park and
Recreation Commission review this and provide a recommendation to the cotmcil on future
spraying in tile parks or not.
Councihnan Boyle: Todd. when was that resolution passed'? Do you recall?
Mayor Jansen: '92.
Todd Gerhardt: '92 I think.
Mayor Jansen: '!992. Actually attached to the packet is tile letter t,at Mr. Hoffman drafted and
to tile Villager addressing tile resident who was concerned. That we weren't doing any mosquito
control, and itl flint it did. and the explanation being we do allow in the mosquito control. It's jr, st
otlr public parks that it ,,,,'as restricted from. I would be supportive of Mr. Gcrhardt's suggestion
to have the Park and Rec Commission take a look at it. since it is our city parks and have that
come up through tile system. Quickly.
Todd (icrh:u'dt: Sure.

certainly' approach tile podium at this time and state your name and address for the record. \Ve
just ask that we try to keep those comments then within about a 5 minute period, and if it is
something that we need to have staffaddrcss as ~'~r as getting back to you. we don't put them on
tile spot here this evening but have them get back to you at a later time. So go ahead and
approach the podium Mr. Smith.
Don Smith: i'm back. I want to bring )'our attention again, in the newspaper that you're up for a

"The c~mmit'tee chair said that

But she as.~rtcd that the bill is reason-

"I know that quite a few ~oplc

I~lso noted.
According to a consorgum of
concerned groups, indudinl[ th~ Si-

least 1:5 percent of gl resMents are
chemically sensitive, aod many people
can become seriously ill from expo-

These groups have been circulat-

the prior-notification role, the posting
of notices and a minimizing of the
use oi' pesticides in public places.
Without waiting for pas.sage of
K~Iso's bill, Todd Hoffman, C'han-
hasstn Park and Rfc'marion Director,
has contacted the MMCD to discuss
advance nbtification before the spray-
ing s~aso~ begins.
"We rant to know in advance
when they will be spaying in Chan-

signs posted noti~'~g citizens of th~
treated areas."
Hoffrnan noted that the city does
not have the rtsourc:s to monitor
trcatrnent in order to guarantee that
aL! spraytng regulaHons are observed
without prior not. cation.
"We simply are not tn a posiHon
to monitor ali the other governmental

now that we are aware of theseprob-

Hoffrnan observed.
Hoffman said that with proper,

easier to have a Community Service

when mosquitoes are l~[ng treated on
