DES MOINES ? If everything is approved, northern Iowa could see wind turbines covering 40,000 acres by 2008.

Iowa Winds LLC wants to build the 200- to 300-megawatt wind farm in Franklin County, but first it has to go to the county zoning board, which will consider approving permits for the $200 million project next month.

“It’s not very often you have someone who wants to make a $200 million investment in the county,” Franklin County Supervisor Michael Nolte said. “That’s a huge investment.”
