Ameren Missouri is recommending that non-conforming decks, patios, gazebos and similar structures be allowed to stay at the Lake of the Ozarks.
Recent controversy has focused on land around the lake, which was formed by a hydroelectric project.
Some landowners feared they would have to raze homes built within the project boundary.
After an outcry, federal regulators last year approved Ameren’s plan to adjust the boundary so about 1,500 homes and businesses could stay.
The utility then had a year to evaluate outbuildings that remained within the project.
On Wednesday, Ameren recommended that regulators let those 215 structures remain because they have no effect on the project or Ameren’s ability to manage the lake.
