The property to the south (adjoining vacant lot) has severely broken sidewalk for about 15 feet and around half the width. There is a 2 inch heave on one side and one crack is large enough to put a hand inside the gap.
Please take a look. A cement patch could fill in the hole and in in the spring, the sidewalk could be repaired.
I would not recommend a city sidewalk plow towing a sander trailer drive over that section.
