Regulated Drain: an open drain, tiled drain, or a combination of the two that is maintained by the county.
Open Drain: a natural or artificial channel that carries surplus water and was established under or made subject to any drainage statute.
* The Surveyor promotes and recommends the USDA/NRCS “Filter Strip Program” along all located ditches.
Tiled Drain: a tiled channel that carries surplus water and was established under or made subject to any drainage statute.
No permanent structures are to be built within 75 feet from either side of any county regulated open or tile drain (totaling 150 feet) without a variance given by the Drainage Board. IC 36-9-27-33
Maintenance: A regulated drain is in need of periodic maintenance when; with or without the use of mechanical equipment it can be made to perform the function for which it was designed and constructed and to properly drain all affected land under current condition, by periodically cleaning it; spraying it; removing obstruction from it; making minor repairs to it.
Reconstruction: A regulated drain is in need of reconstruction when it will not perform the function for which it was designed and constructed; it no longer conforms to the maps, profiles, and plans prepared at the time when the legal drain was established; or topographical or other changes have made the drain inadequate to properly drain the lands affected without extensive repairs or changes including:
· Converting all or part of an open drain to a tiled drain or a tiled drain to an open drain;
· Adding an open drain to a tiled drain or a tiled drain to an open drain;
· Increasing the size of the tile;
· Deepening or widening an open drain;
· Extending the length of a drain;
· Changing the course of the drain;
· Constructing drainage detention basins and drainage control dams;
· Providing for erosion control and for grade stabilization structures;
· Making any major change to a drainage system that would be of public utility.
Watershed: an area of land from which all runoff water drains to a given point or that is affected by a small lake. A watershed area can contain several regulated open and tile drains.
