Report Unserviced Storm Drains

The Mosquito Abatement Courier Team takes pride in the amount of area they are able to cover each round. Our riders and walkers are able to inspect hundreds of storm drains daily, however, we are human and we may overlook a drain. We do not want to leave any storm drain un-inspected, so we would love your help in identifying these drains.

If you have reason to believe a storm drain in your area was not inspected please fill out the unserviced storm drain form.
