Joe if these problems are not fixeda by next spr�ng e will have sunken manholes because of the
Shims that was used and not bung grouted to support the weight of ears and trucks. The debris
wi cause water flOW Droblemsand Passible plug ups in the dines. The grade nrigs NVi I I just
continue to break more and case numerous problems. the buried manhole needs to be found
