The literature search and records review identified no previous archaeological investigations and no known archaeological sites in the Grafton area. It identified nine historic sites, only one of which has been field checked by a cultural resource professional. This site-Williamson House in the city of Grafton--has been declared eligible for the National Register by the North Dakota State Historic Preservation Office. None of the other sites has been subject to a National Register Survey. Of the sites identified in this study, only the rural school in Section 11, T157N R53W seems likely to be impacted by the flood control alternatives under consideration by the Corps of Engineers. The study concludes that the cultural resources of the Grafton area are largely unknown, and recommends that the ground to be disturbed by flood control construction be field surveyed to determine whether prehistoric or historic cultural resources which require protection may exist there.

A cultural resources survey and historical documentary was undertaken at Grafton, North Dakota, to assist in planning for proposed flood control measures. During a spring 1982 revisit to the area, one Burlington Northern Railroad bridge was recoded as an architectural/historic cultural resource site. The documentary research conducted for, and the subsurface tests conducted at, the Plant View Homestead site are sufficient to determine that this site is not significant, nor is it eligible for inclusion on the National Register of Historic Places; the State Historic Preservation Office has concurred with this determination and no further work is recommended for this site. The Railroad Bridge site is considered to have the potential for significance, since it represents what may be the only remaining structures of its kind in the Red River Valley. Recommendations concerning the Railroad Bridge site include implementation of flood control measures in order to avoid the site completely.
