There is an open, unlocked dumpster on the sidewalk of 3946 Haverford. This property is the rear half of the 3939 Lancaster Ave. "Resellers Market", which is a business that sells used furniture, clothing, etc. The trash from this dumpster is usually overflowing and there is usually a pile of trash next to it, including broken glass, food waste, diapers, large furniture items, etc. In addition to health and safety risks, this dumpster usually blocks foot traffic on the sidewalk here. My business is located next door to this property. I have contacted the owner several times by email but the problem is persisting. It does vary from day to day, so it might not be evident on a single pass-by if that comes right after a trash pickup. (The dumpster is a 1 cu yard dumpster supplied by Waste Management Co.).
