6 ABC Action News – PHILADELPHIA (WPVI) — Frustrated neighbors say they have been calling for months to Philadelphia’s 311 help number and have gotten little help. Their problem: short dumping on adjoining vacant blocks of the 2400 blocks of Nassau, Bolton and Redner Streets in the Sharswood section of North Philadelphia. There is a lot of nearby demolition and construction sites and neighbors think waste from some sites is being illegally dumped on the vacant land. Resident Jon Sanborn showed us around the sprawling piles of tires, bricks, furniture and lumber. He showed us videos shot from his home office window of beat up old trucks dumping loads of debris. He says it occurs several times a week.
