The two mattresses were part of a ticket that registered closed on June 26. How are they still there when the ticket is closed?

Public Works uses the term "closed" to mean several things:
-The mess has been cleaned up.
-The problem has been referred to another department (homeless outreach, Fire Department for hazardous waste, Code Enforcement, etc.)
-The problem has been reported twice (or more), and the reports have been combined.
It would be nice if Public Works would be more specific, but that is how their system is set up. So keep that in mind, and keep your blood pressure down!

I drive by this area daily, and these mattresses were not there yesterday.
