Demand to end excessive parking

There is a building at the end of my street where they have so many clients parking that me and the whole neighborhood have to walk about a block or more to there homes and most of us have children. They even are parking on the grass on Washington Ave. I went to talk to the people in the building and explained that it's not fair that I have to walk a block or more to get to my home let alone with 3 kids and they guy said he gives a f*@# less about the kids.
