Thank you to the city of new haven, for the first time in a very long time my street was clean as a whistle, myself and the neighbors are very greatful! We still have a few though who chose to park on the street hampering the efforts of the plows and us as residents who park off street so they can be cleaned. Now those neighbors haven taken up parking where we broke our backs for hours yesterday. Is there something that can be done about this? Talking to them does no good, and the landlord of the home doesn't care at all, he doesn't even come to shovel the sidewalk or stairs.
