The Winding Stair Wind Farm will add an additional 50-60 turbines to northeast Tama County between Traer and Dysart from 150th St south to Elberon.  These along with the existing 60 turbines in the Vienna Farm around Gladbrook and the 60 windmills slated to be constructed by Salt Creek Wind Farm soon between Traer and Garwin will give Tama County more than 180 wind turbines.  They will span our beautiful Tama County countryside the entire 24 mile length and 12 miles wide.   Surrounding Dysart, Clutier and Traer on 3 sides.  The current ordinance for wind energy conversion systems was adopted 24 years ago in 1998.  Research and technology has changed over this time.  This ordinance needs to change as well.  Please stop issuing conditional use permits for wind conversion systems in Tama County.
