The manholes as <br /> noted do become submerged in water due to a drastic grade change <br /> in the Long Lake ditch area down stream froTn the Orono area. It <br /> was discovered that the dirt banks in Long Lake had eroded, creating <br /> a three to four foot dam causing water to backup and flood out the <br /> existing manholes , which eventually created excess flow to the <br /> entire system. We have contacted ��our public works department and <br /> we will be working with them to resolve the problem. <br /> If I can assist you further in these matters, please feel free to <br /> call me . <br /> Sincerely, <br /> ������ _ <br /> Walt R, enson <br /> City Administrator <br /> kil Il l�l'�(:& L(1'�I�G d73-73�7 • �UMI�IS7 k �11C1� dt f ItiA'�C1 373 735b • Yl HLIC�+UkKS �'i 7 3�9 <br /> �S�ISSI\�, <br />
