In August of 2023, the Sumner community voted to create a Library Capital Facility Area (LCFA) to build a new Sumner Library. The Library Capital Facility Area (LCFA) will be an independent taxing district, separate from the City of Sumner, the Library System and Pierce County, for the sole purpose of funding a significant portion of the new Sumner Library.
