Other: The south end of the sidewalk in phase 2 near the gazebo is sinking. There is at least 20 inches of no dirt below the sidewalk, hence it is sinking. The sidewalk is next to the sewer drain where the earth has disappeared and with all of the water problems we have had recently with water mains, the city needs to come inspect. One city worked thought this drain runs right next to departed neighbor Cassie Howard's condo which then should worry us as the ground beneath her condo also disappeared causing her slab to sink and foundation to go bad. These two problems could be connected and the area below the sidewalk cannot simply be filled in with dirt. It has to be inspected including a city inspection. We need to see why it is all sinking.
