Section of retaining wall for the road 4010 along eastern edge. Possible serves same function as well 4037 directly north although alignment is different. There is a space between this wall and the road 4010 which could have functioned as a type of sidewalk, though near road 4010, perhaps marking a possible curb or sidewalk. Building materials and alignments similar to wall 4011, so perhaps contemporaneous.
Wall 4037 and the northern part of 4013
