The dumpster once located in the parking lot belonging to the Corona Mall (not Professional center) located south of our building, has been removed by the City. Since this occurred the tenants of the Corona Mall are using our dumpster on the east side of our building. We are being over-charged by Waste Mgt. because it is over-flowing with trash . I believe the City either needs to get their own dumpster again, or pay for half of our charges by Waste Management.
