Drug addicts/alcoholics have set up a 'camp', which includes furniture under a large tree and subsequent thick bushes in the rear corner of this property. We have repeatedly asked the property owner to rid the problem by maintaining his shrubs. We have had to call police as at times the visitors of this camp are so out of it they have stripped down nude, caught performing sexual acts,using the yard as an open bathroom. It is also unfortunate that the alleyway the runs directly adjacent to this camp is used as a thoroughfare for children going to/from the North Avenue public library. We are requesting that the camp be dismantled and the owner be accountable to the continued blight in the rear of his property.
