The dunes are on the north side of the channel connecting Lake Macatawa to Lake Michigan.
The sand on the north side of the channel is putting pressure on a sea wall and says engineers are afraid the structure could collapse, said Corps spokesman Tom O'Bryan.
"It's not meant for that kind of load," he said.
Crews will spread the 18,000 cubic yards of sand along the shore.
Work began Monday and will take about three weeks, The Holland Sentinel (http://bit.ly/16fbiF5 ) reported. On Monday, crews began to remove the trees and dune grass.
The site is in Ottawa County's Park Township, near Holland.
The work will cost $182,000 and is funded from last year's federal budget, so it's unaffected by the U.S. government shutdown, O'Bryan said.
The mature trees are mostly cottonwood and are being ground into chips to be used in natural areas, said Jody Johnston, park supervisor. He said the dune grass is being harvested so it can be transplanted. The clean sand will then be pushed onto the state park beach.
"When it's done, it will look a lot different," Johnston said.
The new view will allow people to better see the park's lighthouse from the parking lot, Johnston said. He said plans are also in the works to widen the walkway along the channel.
Area resident Mike Mooney said he is unhappy with the project.
"That will be sorely missed," he said as he stowed his fishing gear in the back of his pickup truck Tuesday morning. "That's so picturesque."
Mooney, who has lived in the Holland area for 35 years, said he likes the view with the top of the lighthouse peeking above the dunes and trees.
"People have taken a lot of senior pictures there," he said.
