It occupies a site where mills have operated since the mid-17th century, and it was rebuilt by William Causey after the Civil War. The supplied text does not include the formal significance section, so the stated reasons come from the cover letter and archaeological report.","narrative":"Causey's Mill is a small two-story wood frame grist mill beside Lake Maury and Warwick Boulevard in Newport News. Built around 1866 by William Causey on the site of an older mill damaged in the Civil War, it rests on a stone, brick and concrete foundation. Mills have stood here since the mid-17th century, when the land lay within the Langhorne family's holdings along Waters Creek. The old road across the mill dam once connected both ends of the Peninsula. Creation of Lake Maury in 1931 ended the mill's tidal function and erased the old dam and pond. It is one of only two surviving historic tidal mills on the Peninsula. Rising water and road runoff have undermined its foundation, so state officials endorsed moving it about 50 feet west to higher ground while keeping its orientation and lakeside setting. Archaeological surveys found no additional eligible sites. The city owns the mill under a long-term lease and is exploring restoring its turbine.","period_of_significance":null,"architect_builder":"William Causey (purchased the old Langhorne mill site and rebuilt the mill, completed around 1866)","architectural_style":null,"criteria":[],"status_note":"The foundation is failing from water undermining since Lake Maury was created in 1931.
