In addition, the city's storm and sanitary systems were evaluated. While the sanitary system is of sufficient condition, the storm system was found to have many deficiencies that must be addressed prior to the roadway reconstruction. The storm system in this area is comprised of the original combined sanitary/storm clay tile pipe. The old clay tile is undersized and in many places is shallow and structurally damaged. In addition, the roadway reconstruction project will require that all intersections must replace the sidewalk ramps to mee...
