PARK CITY — To city fathers, the few remaining slivers of undeveloped land left in Park City are priceless as open space.

Actually, the price they would like to pay for some open space is about $10,000 an acre. That's the amount the city is offering the Bureau of Land Management for roughly 116 acres of prime, undeveloped property the federal agency owns within the city limits. The total amount the city wants to pay would be about $1.16 million.

And Park City wants to keep its offer intact, although some others are saying the land is worth many times that amount and that the city's proposed deal would be a colossal rip-off of U.S. taxpayers.

A plan to preserve open space — a plan being pushed by city officials and U.S. Rep. Rob Bishop, R-Utah, along with support from the Sierra Club — is causing a lot of heartburn in the U.S. Department of Interior, BLM's parent agency. Some argue that at the city's proposed price, the deal could be a $100 million loss to taxpayers.

"While we have not undertaken an appraisal of these lands, comparables in the immediate area suggest a valuation of at least $1 million an acre is not unreasonable, meaning the total fair market value of the land being transferred could well exceed $100 million," said Chad Calvert, a deputy assistant secretary for the Department of Interior, during congressional testimony earlier this year.

Beyond the disparity in perceived values, the proposed transaction gets even more complicated and convoluted. And some believe it could run afoul of current federal law.

Open space valued

Park City has long valued its open space. According to Mayor Dana Williams' testimony before a congressional committee earlier this year, the city has permanently protected 4,000 acres of open space, spending more than $35 million since 1990 to acquire those lands.

"In 1998 and again in 2002, by a margin of 75 percent and 80 percent respectively, voters approved raising their taxes to fund a total of $20 million in bonds for the acquisition and preservation of recreational open space," Williams said.

And now the city has its eyes on the 116 acres under BLM management. The city has leased the land from the BLM since 1985 as recreational property under provisions of the Recreation and Public Purposes Act. That lease expires in five years.

The lease, Calvert said, is a source of contention between the BLM and Park City because the city never completed its development plan for the property "and there is no legal public access to the parcel."
