Ewert said grates were stolen from the corners of 31st Street and Alvina Avenue and Honey Creek Drive and Upham Avenue. Another was taken in the 5100 block of South Honey Creek Drive.
“First and foremost, someone could walk by and fall right into them,” Ewert said. “And if you go down, (an adult) can go down up to your waist. A bike, a motorcycle or a car hitting those could cause a lot of damage.
“And if it does rain, all sorts of debris can get in there.”
Ewert said the department has experienced catch basin grate thefts in the past and attributed most of those to kids goofing around with their friends. Three going missing from one section of the city in a short time period, however, is a little more suspicious.
“One is one thing, but three, then we think it might be someone taking them to scrap them,” Ewert said. “But that’s just speculation.”
Ewert said DPW crews and Greenfield police are on the lookout for more missing grates, and encouraged residents who see anyone removing grates other than DPW employees to contact police immediately at 414-761-5300.
