Salt Lake City's Library Square:
Construction: New building north of the current library at 500 South and 200 East. Four stories and 4,800 square feet housing a 50-foot dome with seating capacity for 210 people. Office space and exhibit functions of the planetarium would be housed in the adjacent library.
Financing: Salt Lake County and the Utah Science Authority would work together to finance the construction of the building, estimated to cost $4.5 million.* Salt Lake City would own the building but lease it to the county at a low cost, perhaps $10 per year.
Management: SciTech at no cost or the University of Utah with a goal of eventual privatization of the planetarium.
Parking: Underground parking would accommodate up to 280 visitor vehicles a day and more than 500 in the evening. More than 100 on-street parking stalls surrounding the block.Gateway:
Construction: New building, unofficially termed an "Explorium" at the Gateway development at 400 West and 100 South. An IMAX theater and the Hansen Planetarium would share the same three-level building. The development is part of a three-part cultural venue that would include a four-level Children's Museum of Utah. Floor area for the planetarium is 27,500 square feet. Total project space is two linked buildings with more than 97,000 square feet.
Financing: Requires a $20 million bond financed by Salt Lake County, which spends $1.3 million per year to operate the planetarium. Under this proposal, the $1.3 million would continue to be paid each year to retire the bond debt. The county would own the planetarium building and exhibits and lease it back to the Explorium at a nominal rate for 99 years.
Management: Children's Museum of Utah. Management fee of 10 percent of the planetarium's operating budget, about $300,000 a year.
Parking: 2,400 spaces of sheltered underground parking, plus on-street parking.
*Proponents of Gateway say Salt Lake City Mayor Rocky Anderson's numbers are flawed and say the total project cost, with seismic upgrades, would be closer to $25 million. Anderson stands by his numbers.
