One generation’s trash is another generation’s treasure, and now a landfill-turned-park in Downingtown is at the center of a dispute that’s made its way to the Pennsylvania Supreme Court.

A deal to sell 28 of Kardon Park’s 48 acres for a mixed-use development has been stalled since 2007 over a dispute about whether the Downingtown Borough Council has such authority, and it’s now the Supreme Court’s turn to weigh in, according to a Philadelphia Inquirer report by Michaelle Bond.

“This is such an important case,” opposition attorney H. Fintan McHugh said. “There are hundreds of parks that could be sold without any court review or public participation.”

Downingtown’s $3.1 million deal would give a portion of Kardon Park to Progressive Housing Ventures, which has plans to build retail space and 300 housing units. The development would also create public space and walking trails, the article explained, and it promises $100,000 or more each year in tax revenue.

The case opened with oral arguments last week. Read more about the Kardon Park controversy in the Philadelphia Inquirer here.
