Deschutes County Commissioners are giving Tetherow Resort six more months to complete foreclosure proceedings.  They are also allowing resort managers to clarify who owns what, before they must build roads and utilities.  The Deschutes County Board of Commissioners made the decision yesterday and it affects a portion of the distressed resort just outside of Bend.  According to an article in the Bulletin, developer TD Cascade Highlands LLC is already a year late in buildings roads, sewers and other fundamental requirements.   The infrastructure work was supported to be done by June of 2011.
