By Rick Steelhammer Members of Yeager Airport's finance committee recommended a review of more than $1 million in expenses paid out after the March 12 landslide, after several hundred thousand dollars worth of checks were questioned on Tuesday.Also Tuesday, airport officials said they would install concrete barriers along Barlow Drive below the landslide, as debris continued to fall from the hillside.The airport's full board of directors will be asked Wednesday to authorize the review of the money spent after the landslide, since emergency-spending procedures were put in place following the original slope failure at Yeager's main runway safety-overrun area.The airport's finance committee voted on Tuesday to recommend the review after members were presented with copies of four checks totaling $650,000 written by the airport between April and June to Corotoman Inc., which owns property in neighboring Northgate business park."All these payments should have gone through the construction committee and then been approved by the board," said Trip Shumate, finance committee chairman and vice chairman of the airport's governing board.
