FLETCHER, Chief Justice.
Suzanne Eardley appeals from an order of the Fulton County Superior Court denying the existence of an implied easement in favor of Eardley over her neighbor's property. Finding no error in the trial court's ruling, we affirm.
In 1989, a one-acre tract of land, fronting 150 feet on Jett Road, was conveyed to M. Kenneth McGreevy, as Trustee. In 1997, the Trustee conveyed to Hutchins and Cole a portion of this property, fronting 100 feet on Jett Road, upon which was located a small house (the "Eardley property"). The deed did not reference a recorded plat, nor did it make any mention of a gravel drive or any type of easement over the portion of the original tract retained by the Trustee. A plat was prepared at that time which accurately showed by metes and bounds the Eardley property and the tract remaining in *745 the trust (the "McGreevy property"). The plat generally showed an existing gravel drive extending from the small house to the west property line of the Eardley property and across the McGreevy property down to Jett Road. No dimensions of the drive were indicated, and the plat was never recorded.
Eardley purchased her property from Hutchins and Cole in 1998, and claims to have received a copy of the plat showing the gravel drive to Jett Road crossing the McGreevy property. The plat was not recorded, nor was it referenced in Eardley's deed. For a short period of time, Eardley used the drive crossing the McGreevy property to access the house from Jett Road.
In this quiet title proceeding,[1] the special master determined that an implied easement had arisen in favor of Eardley with respect to the drive.[2] The trial court rejected that conclusion, however, and ruled that no implied easement had arisen because the right of way was neither necessary for access to the Eardley property, nor was the plat showing the drive recorded or referenced in Eardley's deed.
1. An implied easement may arise when "the right is necessary to the enjoyment of lands granted by the same owner."[3] Thus, when an owner of land conveys a portion of that land to another, and the only access to a public road from the conveyed property is over the portion of the property retained by the grantor, an implication arises that the grantor intended to convey a means of access.[4] By implication, therefore, in such circumstances the law will recognize the grantee's right to access the conveyed property through a right of way over the property retained by the grantor.
The record shows, however, that the Eardley property borders a public street known as Jett Road, and that Eardley could access Jett Road from her property without unreasonable difficulty.[5] Therefore, the access to and from the residence across the McGreevy property is not necessary, but merely convenient, and the interests of convenience are insufficient to establish an implied easement.[6] Eardley cannot "claim a road over another's land as a road or way of necessity when [she] has, or can have, a road over [her] own."[7]
Eardley claims that under the rules pertaining to subdivisions, her reliance on the plat, showing the drive over the McGreevy property, is sufficient to establish the existence of an implied easement.[8] "When a grantor sells lots of land, and in his deeds describes them as bounded by streets, not expressly mentioned in the deeds, but shown upon a plat therein referred to as laid out in a subdivision of the grantor's land, he is estopped to deny the grantees' right to use the streets delineated in such plat."[9]
But in those cases in which a common grantor was estopped from denying the existence of an easement based on a plat showing the easement, the plat was either recorded,[10]*746 or referenced in the grantee's deed.[11] In this case, to the contrary, Eardley's deed makes no mention whatsoever of the plat or of any right of way bordering the property, and the plat itself was never recorded.[12] Furthermore, the plat itself merely shows the existence of a drive, but does not describe the drive as any type of right of way for the Eardley property.[13] Under Eardley's reasoning, an unrecorded plat, prepared for anyone in the back chain of title, that showed any type of access route, could bind present and future landowners regardless of whether they had ever seen the plat, or whether they even had any way of finding it. To adopt such a ruling would unreasonably expand the Georgia law of implied easements, and would do great harm to the predictability of land titles.
2. In the alternative, Eardley argues that the trial court had no authority to reject the conclusions of the special master. But in submitting a quiet title case to a special master, the trial court does not cede jurisdiction to render a final decision, and the trial court is not obligated to accept a special master's erroneous legal conclusion.[14]
Judgment affirmed.
All the Justices concur.

[12]  Generally, a plat prepared from a survey in order to convey a single portion of a tract of land should not be considered a subdivision, as that term is contemplated by the cases cited in footnotes 8-11. In each of those cases, the subdivision involved the creation of multiple lots and streets, evidencing a comprehensive scheme for the development of the property.
