The area known to some locals as "Mount Trashmore" is set to close again, nearly five years after it reopened.

The Linn County Solid Waste site 1 reopened shortly after the 2008 flood to take in tons of flood debris. It stopped taking that debris in November.

Now, the Cedar Rapids/Linn County Solid Waste Agency will take bids in April to cover the landfill with dirt and seed it with grass. The entire process to close the landfill site is expected to cost about $3.2 million.

After the site is capped, officials hope to redevelop the site with a park or recreation trail. But those efforts would have to wait.

"There will be settling over the next ten years," said Joe Horaney of the Cedar Rapids/Linn County Solid Waste Agency. "It could settle 30 feet, so we'd have to wait 10 years to consider things like trails or sledding or skiing or anything like that."

The Site 1 landfill opened in 1965 along the Cedar River in what had been the Otis Quarry. It closed the first time on July 31, 2006, leaving the agency with just one active landfill, the Site 2 landfill.

In the time that it was reopened, the Site 1 landfill took in 427,000 tons of flood debris and actually grew 34 feet higher. It also took in $25 million in fees, with most paid by the Federal Emergency Management Agency.
