During the
Iowa flood of 2008, the
Cedar River overflowed its banks, flooding the museum and library with of water and causing severe damage to the exhibitions and contents. The damage was variously valued at $8 million or $9 million. The flood occurred just days before the museum was scheduled to reveal its choice among four proposals for a tripling in the size of the facility. Museum staff were able to remove two trucks full of museum and library material before the flood.
Fine art and
folklore artifacts were prioritized for removal. The library held an estimated 30,000 Slovak and Slovak-related items in its library, two-thirds of which are stored off-site and were not affected by flood damage. Around 40 percent of the museum's artifacts are Slovak. The museum holds the largest collection of
kroje outside Slovakia and the Czech Republic, with the oldest pieces dating to the 16th century. After the flood, a temporary facility was opened at
Lindale Mall. The museum's temporary home was moved in April 2010 to the Kosek Building at 87 Sixteenth Avenue SW in Cedar Rapids, built in 1910. The interim space, including a gallery and museum
gift shop, was opened. An exhibition, "Rising Above: The Story of the People and the Flood" also opened at that time. The exhibit focuses on the 2008 flood, comparing it to the previous floods of 1929 and
1993, and includes materials from the NCSML's Flood Oral History Project, an
oral history project of the personal accounts of flood victims. The exhibit tells the story of the flood in conjunction with the history of Cedar Rapids, the
Czech Village, and New Bohemia. The Kosek Building continues to be a part of the Museum and Library after the main building was rebuilt. The
Iowa General Assembly set aside $10 million to help the museum and library rebuild. In October 2008 the Czech ambassador presented a $405,000 donation from the Czech Republic for reconstruction efforts. The museum decided to move and expand the museum to higher ground, rather than demolishing the original building, because the cost to move the 15-year-old building was $713,000, compared to an estimated $2 million to demolish and rebuild the structure. A groundbreaking ceremony was held on December 15, 2010. The museum dubbed the event "A Monumental Move" and set up a
webcam for viewers to watch the move; the City of Cedar Rapids also shut down 16th Avenue SW, including the Bridge of Lions, so local residents could watch. In addition to moving the first building to a new location, the rebuilt facility is significantly expanded, to a total of including "larger permanent and temporary exhibition galleries, an expanded research library, educational programming space, a new museum store, collection storage, and work space." The rebuilding and recovery costs are estimated to be $25 million. In 2010, the museum launched a
capital campaign with a goal of raising $25 million to establish the Kosek Building as part of the NCSML's permanent collection, renovate The Immigrant Home and the Babi Buresh Center
historic homes for tour, design and install a new permanent exhibition, recovery money spent by the museum and library on disaster cleanup; and grow the endowment to pay for
operating expenses. The NCSML stated that following the museum's reopening, an estimated 54,000 visitors will visit annually and the economic impact on the Cedar Rapids area will be over $1.1 million. == Buresh Immigration Tower and Astronomical Clock (Orloj) ==
