A Century Farm or Centennial Farm is a farm or ranch in the United States that has been officially recognized by a regional program documenting the farm has been continuously owned by a single family for 100 years or more. Any farm owners in Hay Creek Township who have that status and would like to have their farm information included in this section should contact one of the supervisors or the township clerk.

The additional subheading under historic buildings should be entitled “Civilian Conservation Corps Camp”. The following introduction can be the opening paragraph:

The Civilian Conservation Corps (CCC) was a voluntary public work relief program that operated from 1933 to 1942 in the United States for unemployed, unmarried men. Originally for young men ages 18–25, it was eventually expanded to ages 17–28. The Corps operated a camp in the northeast corner of the intersection of Hwy 58 and Old Church Rd. The camp buildings, with the exception of the well pump house, have all been removed and residential dwellings have been constructed. The well and structure housing its pump remain operational for the local residents. The homes are accessed by Old Camp Lane.
