Congress has appropriated some funds for the memorial's design and construction, however. Congress appropriated $16 million in the Department of the Interior, Environment, and Related Agencies Appropriations Act, 2010 (P.L. 111-88; October 29, 2009), and $30.99 million in the Consolidated Appropriations Act, 2012 (P.L. 112-74; December 17, 2011). The 2011 legislation was also important because it allowed the commission to meet a critical fundraising challenge. The Commemorative Works Act requires a memorial foundation to raise 75 percent of the construction costs before the Department of the Interior is permitted to issue a construction permit. Additionally, the CWA requires a memorial foundation to raise an additional amount, equal to 10 percent of the memorial's total construction costs, for deposit in a memorial maintenance trust fund (administered by the National Park Service). The 2011 legislation declared that the funds provided by Congress thus far shall be deemed to be sufficient to meet both fundraising requirements of the CWA.
