v.
INGHAM COUNTY ROAD COMMISSION
Docket No. 11840.
Michigan Court of Appeals.
Decided May 1, 1972.
*439 Russel A. Lawler, for defendant.
Before: McGREGOR, P.J., and J.H. GILLIS and O'HARA,[*] JJ.
PER CURIAM.
Plaintiffs appeal the denial of an injunction sought against defendant to prevent it from entering upon their land to remove certain trees for the purpose of widening Williamston road in Williamstown Township, Ingham County.
It appears that the trial court based its decision upon the erroneous view that a right-of-way for a highway obtained by prescriptive use is always to be four rods in width regardless of the extent of the actual use. This view was understandably fostered by the statute, MCLA 221.20; MSA 9.21:
"All highways regularly established in pursuance of existing laws, all roads that shall have been used as such for 10 years or more, whether any record or other proof exists that they were ever established as highways or not, and all roads which have been or which may hereafter be laid out and not recorded, and which shall have been used 8 years or more, shall be deemed public highways, subject to be altered or discontinued according to the provisions of this act. All highways that are or that may become such by time and use, shall be 4 rods in width, and where they are situated on section or quarter section lines, such lines shall be the center of such roads, and the land belonging to such roads shall be 2 rods in width on each side of such lines."
This Court has held that when a highway is appropriated for public use by the principle of *440 user, there arises only a statutory rebuttable presumption that the right-of-way is four rods in width. In cases where the presumption is so rebutted, the roadway is restricted to that area actually appropriated and used for road purposes. Laug v Ottawa County Road Commission, 37 Mich App 757, (1972); see, also, Eager v State Highway Commissioner, 376 Mich 148 (1965); Yonker v Oceana County Road Commission, 17 Mich App 436 (1969). Plaintiff having introduced evidence to rebut the statutory presumption, thereby placed this case within the category of cases in which the right-of-way is confined to that portion of land actually used for highway purposes.
Since a right-of-way is deemed to encompass such use of the land at or beneath the surface as will make the easement effective, a similar concept of use must be employed in determining "actual use". Highland Park v Driscoll, 24 Ill 2d 281, 283; 181 NE2d 93-94 (1962). Hence, where the facts establish a public use not only of the road itself but also of a bordering drainage ditch, it having been proven essential to the effectiveness of the right-of-way, prescriptive rights will be created in the ditch as well. Highland Park v Driscoll, supra.[1] However, though the width of a prescriptive easement in a public highway includes shoulders and ditches needed and actually used, it does not include the allowance of a width for shoulders and ditches not used but needed. Grenell v Scott, 134 So 2d 866, 869 (Fla App, 1961). Hence, the boundaries and the extent of use of the ditch at the time the easement was created must be determined by *441 the trier of fact in order to resolve the ultimate issue of whether the land upon which the trees are located is within the right-of-way.
Reversed and remanded. No costs, a public question being involved.
