ORONO REGULAR COUNCIL MEETING HELD JUNE 11, 1990 ZONING FILE #1502-HILBELINK CONTINUED Hilbelink also informed Council that he had beer, on the property since the heavy rainfalls occurred. He said that there was no standing v/ater on the lot. He '7'’'“stioned whether it was possible to provide for a 100 year storm. Mayor Grabek asked why the house plan submitted was not the actual plan that would be used to construct the house. Mr. Hilbelink replied that it will be necessary to downsize the plan shown, but that he was not asked to provide the City with the exact specifications.

Mabusth said that the Jentiluccis are asking the City to solve the drainage problem and are willing to grant an easement over a portion of their property. Mabusth said that it may be necessary for grading changes to be made to prevent drainage from flowing onto Jentiluccis' property.
