The Hamilton County Surveyor's office requires a permit for crossing, outletting or working within the easement of a regulated drain. Regulated drains in Hamilton County consist of subdivision drains, field tiles, or open ditches and creeks.
Failure to Obtain a Permit
Failing to obtain a permit for work done on these drains will constitute a violation from the surveyor's office. The Hamilton County standards and specifications as published by the Surveyor's office must be met and approved prior to the beginning of the work.
