Back in February, after Montclair was hit with nearly 19 inches of snow, the township faced a logistical problem: where to put all the plowed snow, salt, and road debris. The answer turned out to be two local parks — Essex Park on Chestnut Street and Erie Park on Walnut Street — where contractors working for the township dumped massive piles of compacted snow and ice. Over the following weeks, those piles became a source of growing frustration, concern, and online speculation among residents.
