� . . . <br /> Sewer Overflow (CSO) work currently under design. Accordingly, <br /> no rehabilitation work is applicable at this facility. <br /> The Cantrell St. Sewer downstream from Jackson St. features <br /> a number of various sizes and shapes as noted before. Sewer <br /> condition is generally poor with some areas where critical struc- <br /> tural problems have developed. Accordingly we summarize the <br /> various sewer sections, previously identified, as follows: <br /> 4. 8�± transition section immediately weat of Jackson <br /> Street: Mortar in the brickwork is heavily eroded. <br /> The downstream 4 to 6 ' of transition has been patched <br /> with gunite. Patching is in very poor repair, heavi- <br /> ly deteriorated with wire mesh exposed, the crown <br /> separated and some small voids apparent. This sec- <br /> tion has the potential for structural failure (see <br /> photos 1-3 between MH C-6 and MN C-5) . Construction <br /> of the new diversion facility, noted above, should <br /> include replacement of this transition section. <br /> Accordingly it is not included herein as part of this <br /> proposed rehabilitation work. <br /> 5. 80 LF ot 48�� x 42�� concrete box seation: Heavy <br /> debris is deposited in the flat bottom of the box. <br /> Extensive deterioration of concrete is apparent at <br /> the junction of wall and floor with a void extending <br /> completely through the wall (see photo 4, MH C-6 to <br /> MH C-5) . openings in the crown of the box sewer are <br /> covered with wood planking.
