The Scientific & Cultural Facilities District is a voter-approved special district in the seven-county metro area that provides a stable source of supplemental funding to more than 300 scientific and cultural organizations inside the district's boundaries. The SCFD collects a one-tenth of 1 percent sales-and-use tax (or one penny on every $10 spent), providing approximately $40 million each year to area cultural attractions both small and large.
