The asphalt on South Clark was recently repaired (I assume because of a recent water main break), and the new asphalt has sunk in somewhat. It's not clear that it's safe. This is on the street at the end of a driveway between 126 and 128 South Clark Street.
While this area is under construction, I wonder if you could fix the drainage on northwest corner of the intersection of 6th and Adams. The storm drain sits slightly above the pavement on one corner. The intersection itself may also be below grade. The intersection collects an inch or two of water when it rains.
Maybe a complex problem, but there is often standing water (rain or shine, but especially when it's been raining) on the sidewalk and the street in the block just east of Walnut on the south side of 12th Street. .
