Alpha WARD
v.
SUNSET BEACH AND TWIN LAKES, INC.
No. 8013DC757.
Court of Appeals of North Carolina.
July 7, 1981.
*891 Ray H. Walton and William F. Fairley, Southport, for plaintiff-appellant.
Grover A. Gore, Southport, for defendant-appellee.
BECTON, Judge.
Plaintiff has assigned error to the trial court's order denying "enforcement of the previously existing dedicated easement to her lots." She has also assigned error to the following two findings of fact:
9. That Main Street as shown on the 1955 Map has been abandoned but if it could be relocated it would run between the present line of sand dunes on the south side of the island and the Atlantic Ocean and upon the beach strand. It would also run into the inlet and the Inland Waterway on the north portion of the island.

*892 10. Main Street as shown on the 1955 Map would be impossible to reconstruct or maintain.
Plaintiff asserts that the record fails to show any evidence of abandonment of Main Street as shown on the 1955 Map (Old Main Street), and we agree. Gore testified that Old Main Street was never withdrawn from dedication. Once an easement is established by dedication, it can only be abandoned by an intention to relinquish the interest accompanied by "acts and conduct positive, unequivocal, and inconsistent with [one's] claim of title." Banks v. Banks, 77 N.C. 186, 187 (1877). Furthermore, a mere lapse of time or other delay in asserting one's claim to an easement unaccompanied by such acts and conduct clearly inconsistent with one's rights does not constitute a waiver or abandonment. Id.; Miller v. Teer, 220 N.C. 605, 18 S.E.2d 173 (1942). Simply put, there was no easement, indeed no Main Street, to use during the period of time the eastern portion of Sunset Beach was submerged, and consequently, no abandonment of the easement.[1]
Defendant argues that the easement was, in effect, abandoned when the land was washed away, and that thereafter, when defendant reclaimed the land, defendant had no duty to reconstruct Old Main Street. We agree that defendant had neither a duty to reclaim the land nor a duty to rebuild Old Main Street. However, once the portion of Sunset Beach, which included plaintiff's lots 3 and 4, was reclaimed, plaintiff once again became fee simple owner of those lots and was entitled to the easement as it existed at the time plaintiff first acquired the two lots. While not directly on point, the principle in State v. Johnson, 278 N.C. 126, 179 S.E.2d 371 (1971), that accretion and erosion do not change boundaries unless the body of water is a boundary line, is instructive. The court in Johnson stated: "[A] `traveling inlet' does not uproot and supplant a boundary line as it passes over it unless such inlet in fact was the boundary when it started its journey." Id. at 148, 179 S.E.2d at 385. Plaintiff in the case sub judice contends that since the effects of natural accretion and erosion did not affect the fee simple title to appellant's property in Johnson, then neither should the erosion and subsequent reclamation affect the property interest plaintiff has in the easement. We agree.
We are guided by an 1897 Illinois Supreme Court decision which appears to be directly on point with our holding. City of Chicago v. Ward, 169 Ill. 392, 48 N.E. 927 (1897). In Ward, the plaintiffs, property owners, sought to enjoin the defendant City from erecting buildings on "reclaimed" land adjacent to their property. Plaintiffs claimed this land had been dedicated as a park when the area was platted. The plat, which was amended in 1836 and 1839, described certain land along the lakefront which was left vacant and was not subdivided. The plat was marked: "Open ground. No building. Public ground. Forever to remain vacant of building." In 1844, the City of Chicago, by resolution, declared that the open space should be enclosed as a public park. In 1847, 1851 and 1856 the land was designated as "Lake Park" in successive ordinances. The controlling issue in the case concerned land which was carried away by the waters of Lake Michigan and later reclaimed. The Illinois Supreme Court held:
[T]he title to these lands submerged by the action of Lake Michigan was not lost, *893 and that by their subsequent reclamation the city has completely reasserted its title thereto, as such title stood at the time of the dedication of the respective plats thereof. The trust impressed on them was that they should forever remain free from buildings, and it cannot be said that while they were submerged they were subject to be built upon. We do not see that the submergence and subsequent reclamation altered or destroyed the trust upon and for which they were held. As the city had, as we have seen, the fee in this park, impressed with the trust declared by the dedicators, the legislation of 1861 and 1863 added nothing to its trust, and can only be looked upon as confirmatory of the same.
Id. at 408, 48 N.E. at 932. See also Mulry v. Norton, 100 N.Y. 424, 3 N.E. 581 (1885). The Illinois court emphasized that the restriction of the land as a park created a vested right attaching to the abutting property owners by virtue of the original dedication. The court also presumed that the plaintiffs in Ward purchased their lots because of the enhanced value of the lots from the dedication.
Just as the City in Ward reclaimed title to its land as the title stood at the time of dedication, so too can plaintiff in this case reassert her title as it stood when she purchased the two lots. Plaintiff's vested right in the easement, depicted as Old Main Street, was reclaimed along with lots 3 and 4. Plaintiff's lots 3 and 4, even more so than plaintiffs' property in Ward, are enhanced by this easement. Without the easement, plaintiff's land would be accessible only by the ocean.
We feel that the tenor of prior North Carolina decisions is consistent with our holding. For example, in Insurance Co. v. Carolina Beach, 216 N.C. 778, 7 S.E.2d 13 (1940), in which the width of a dedicated street was subsequently reduced from ninety-nine feet to eighty feet,[2] our Supreme Court held:
[T]he New Hanover Transit Company [predecessor in title to plaintiff corporation], having made a map of its land, platting it into lots and streets, showing Lake Park Boulevard as a street ninety-nine feet wide, and having sold lots with reference to such map, thereby irrevocably dedicated the streets, including Lake Park Boulevard, to the use of the purchasers of lots so sold, and those claiming under them, and is estopped to deny the right of such purchasers, and those claiming under them, to an easement in all the streets represented and as represented on the map at the time of the purchase and conveyance with reference to it  irrespective of whether the town, when it was incorporated, accepted and opened the streets to their full width. The right of prior purchasers, and those claiming under them, to this easement was unaffected by the change of the map in 1916, even if it be conceded that the change was made pursuant to corporate action.
Id. at 787, 7 S.E.2d at 19. As support for its holding in Insurance Co. v. Carolina Beach, the Supreme Court cited numerous cases sustaining the following principle:
[I]f the owner of land, located within or without a city or town, has it subdivided and platted into lots and streets, and sells and conveys the lots or any of them with reference to the plat, nothing else appearing, he thereby dedicates the streets, and all of them, to the use of the purchasers, and those claiming under them, and of the public....
Id. at 785, 7 S.E.2d at 18. The reason for this principle is:
[T]hat the grantor, by making such a conveyance of his property, induces the purchasers to believe that the streets and alleys, squares, courts, and parks will be kept open for their use and benefit, and having acted upon the faith of his implied representations, based upon his conduct in platting the land and selling accordingly, he is equitably estopped, as well in *894 reference to the public as to his grantees, from denying the existence of the easement thus created.
Green v. Miller, 161 N.C. 24, 30, 76 S.E. 505, 507 (1912). This principle and its rationale are equally applicable in the case before us. It seems clear in this case, as in most cases, that plaintiff was induced, in part, to purchase lots 3 and 4 because the lots were accessible by some means other than the ocean. Once defendant reclaimed plaintiff's land, plaintiff once again became fee simple owner with rights to her land, including access by way of the easement, as it existed at the time of purchase. Defendant could not revoke the easement as shown on the 1955 Map by having a new map platted.
We find it unnecessary to deal with plaintiff's assignment of error dealing with the finding of fact and conclusion of law that Old Main Street would be impossible to rebuild. As we earlier noted, since defendant was under no duty to reclaim plaintiff's land, defendant is under no duty to rebuild Old Main Street. Defendant has conceded though that once it reclaimed plaintiff's lots, plaintiff owned this land. We hold, therefore, (1) that plaintiff retains an easement for purposes of ingress and egress to her lots in and over the entire area of Main Street, as that street was depicted on the 1955 Map; and (2) that plaintiff is not otherwise entitled to an easement by necessity to her lots across the lands of defendant, to and from Main Street as it now exists.
Affirmed in part; reversed in part.
VAUGHN and WELLS, JJ. concur.
NOTES
[1]  Even assuming there had been an abandonment, we adopt the principle that when there has been a legal abandonment of a dedicated street, abutting property owners retain easement over the abandoned street to the extent necessary to allow reasonable ingress and egress. See Potter v. Citation Coal Corp., 445 S.W.2d 128 (Ky.1969). This principle is consistent with G.S. 136-96 which provides that when a road or street is not used within fifteen years after dedication and when a declaration of withdrawal is recorded, the road is deemed abandoned. An exception in this statute, however, provides that this provision shall not apply "where the continued use of any strip of land dedicated for street or highway purposes shall be necessary to afford convenient ingress or egress to any lot or parcel of land sold and conveyed by the dedicator of such street or highway." See Andrews v. Country Club Hills, 18 N.C.App. 6, 195 S.E.2d 584 (1973).
[2]  The reduction in width of this easement was carried out "to take care of erosion affecting the ocean front lots already sold and, as the said president [of the corporation] testified, `to help us in the sale of other lots.'" 216 N.C. at 783, 7 S.E.2d at 17.
