This area is right above a City Sewer that was placed in 2016. The area has gradually sunken over last 2 years (I have photo from Feb 2017 showing how the curb was broken along the same line above the sewer). The curb was just fixed but you can see how the area behind (on the grass) and the area before the curb (on the road are still dipped in). I think someone needs to be sure that the area above sewage line is compacted properly, because any cosmetic fix now will not solve the issue. Please also note that the walkway has been fixed twice now (2018 and 2019) in the same area, but it keeps coming back... I think the ground needs be stabilized first.
