Rosie,

 

As I promised on the phone a few minutes ago, attached is an email that was forwarded from Hilda Suarez to Tom Marco regarding my concerns about mosquito breeding in storm drains.  Can you please help me find someone who can address my concerns?

 

Thank you,

Mr. Burgess and Mr. Renfrow:

 

In reference to the email message I originally sent on October 31, 2003

(included below), the Public Works Department Mosquito Control Division has

confirmed my fears.  These new storm drains are holding water in such a way

that they are already breeding mosquitoes.  Considering that November is not

our typical heavy mosquito season and that these drains are only

approximately one month new, I think it is a reasonable assumption that

without design corrections we are going to have serious mosquito problems in

the future.

 

So I ask, how can the design of these drains be changed to eliminate the

standing water?

 

I am not an engineer, but it seems something as simple as filling the

concrete manifolds with gravel and sand up to the level at the bottom of the

lateral pipe connections might help.  In that way, water would be forced to

flow into the lateral pipes, where it would quickly seep into the drain

field.

 

Please, help to quickly correct this problem before our neighborhood becomes

one of the county's top mosquito breeding areas.

 

Again, my thanks to Mr. Nelms and his staff for rapidly responding to my

concerns and offering to continue to treat the storm drains with insecticide

to kill the mosquito larvae whenever we report mosquito problems.

 

Thank you,

 

Regards,

Mike Pryslak

Mr. Pryslak:

 

An inspection was made in your area on November 4, 2003 in response to your

concern of mosquito breeding in storm drains.

 

Forty-Four (44) drains were inspected.  Seven (7)(16%) were breeding

mosquitoes.  The drains were treated with insecticide to kill the mosquito

larvae.

 

The insecticide has a residual effect, and will provide extended control of

the mosquito breeding.

 

Mosquito breeding was found  in containers on six (6) properties.  All

mosquito breeding was eliminated.

 

Please contact me if you have any mosquito related problems in the future.

Mr. Nelms,

 

Thank you very much for your speedy reply.  I am hopeful these new drains

will not cause problems.

 

To the best of my awareness, there is not a mosquito problem in our

neighborhood currently.  These drains have only been installed within the

last month.  I doubt your inspectors will find active breeding tomorrow,

however, they will see how the drains hold water.

 

My concern is that by adding approximately one storm drain for every two

houses, we will have mosquito problems in the future.  Your statement that,

"It is not unusual for storm drains to breed mosquitoes" causes me concern,

however, I will trust your judgment and remain hopeful that these drains

will not cause problems in the future.

 

Thanks again,

Mike Pryslak

Mr. Pryslak:

 

Your e-mail to Public Works regarding mosquito breeding in storm sewers in

Westwood Lakes was referred to mosquito control for response.

 

We will have an inspector in your area on Tuesday, November 4, 2003 to check

the drains and properties for mosquito breeding as well as  for adult

mosquitoes.

 

Any mosquito breeding will be treated with insecticide to abate the

breeding.

 

It is not unusual for storm drains to breed mosquitoes.  Storm drains are

designed to collect run-off water, and many hold water for extended periods

of time.  Storm drains are in many instances favorable areas for mosquito

breeding.  The mosquito species usually found in the storm drains do not

constitute a significant biting nuisance.

 

I do not believe a public health problem will be created with the

installation of french drains in your neighborhood. We will happily respond

to any complaint of mosquito nuisance, and usually respond within 24-48 hour

after receipt of the complaint.

 

We are allowed to treat storm drains with insecticide when mosquito breeding

is found.

 

Please contact me if you have any questions regarding this matter.

 

I will let you know the results of our inspection.

 

Marlon Nelms, Chief

Mosquito Control Division

I am concerned that the neighborhood projects to install new storm sewers

are going to create public health problems.  The design of the French drain

system being installed in my Westwood Lake neighborhood is flawed in that

standing water is collecting under each drainage grate, creating a breeding

ground for disease-carrying mosquitoes.

 

Starting at the surface, this design includes a drainage grate on top of a

large concrete cylindrical manifold standing upright (think of the shape and

orientation as a soup can sitting on a grocery shelf).  Connecting to the

side of this manifold are lateral perforated pipes in a French drain field.

 

The problem with the design is that the lateral pipes are connected high

above the bottom of the concrete manifolds, and the bottoms of the concrete

manifolds have inadequate drainage capabilities.  The net result is that

standing water collects in the bottoms of the concrete manifolds.

 

Looking through the grates while strolling throughout my neighborhood,

almost every manifold contains standing water approximately four feet below

[its] grate.

 

These manifolds are going to become breeding grounds for mosquito larva. The

large number of such manifolds throughout the county will make it impossible

for the Public Works' Mosquito Control Division to adequately treat this

standing water with larvicide.  (In my neighborhood, the project is

installing approximately one manifold for every two houses!)  Even if the

county were to fund the Mosquito Control Division adequately to repeatedly

treat all these manifolds, I believe it is against DERM regulations to put

anything in a storm sewer other than rainwater.

 

I realize the county has made a substantial investment in these storm sewers

and similar projects are underway throughout the county.  However, I

strongly believe that if these projects are not stopped before the designs

can be corrected to solve this problem, we will be faced with serious

mosquito and mosquito-borne disease problems.
