Dealing with dog waste on 1st W

I live on 1st street west with my Australian Shepherd. I love the area and the building, however there's few spots close by for her to go the bathroom. She has to resort to planters or the sidewalk (which I really don't like being a resident on the street). There is grass at Chesterfield, but she can't always wait that long. The older she gets, the more concerned I am about this.
