For those seeking relief from lugging around those big and bulky green garbage cans that the city recently parked by your front door, you now have a chance to exchange the cans for a more compact 35-gallon version.

But you better hurry.

Ever since the Department of Public Works announced the exchange program this morning, calls for the smaller can have snowballed, according to 311 operators where the public can request the exchange.

Originally, the 35-gallon cans were available only to properties that were part of a block-long group of rowhouses that have front trash pick-up.

DPW is now offering the smaller cans, on a first-come/first-serve basis, to those who call 311 .
