This case concerns a zoning ordinance dealing with the regulation of signs which was adopted by the Winston-Salem Board of Aldermen on 15 April 1985. The part of the ordinance which is the subject of this appeal is the portion dealing with “off-premise grounded signs,” defined in the ordinance by reference to size, zones, height, spacing, setback, distance from residential zones, number of faces, measurement, illumination, and C.B.D. view corridors. This ordinance contains an amortization schedule for these off-premise grounded signs stating that “[a]ll non-conforming off-premise signs shall be removed or brought into compliance with all requirements of this ordinance . . . within 7 years of the date of its adoption.” The ordinance further stated “[t]his ordinance shall become effective upon adoption.”
By letter to plaintiff dated 31 October 1986, defendant stated, in pertinent part, “that the following signs are in violation of the City of Winston-Salem Sign Ordinance and must be removed by April 15, 1992, in accordance with Section 25-12(f) of the Winston-Salem City Code.” This letter made reference to signs located along 1-40, Highway 52 and Corporation Freeway (those being Federal Aid Interstate and Federal Aid Primary Highways), and these were attached as Exhibit A. The letter further noted that those signs may be eligible for compensation pursuant to North Carolina General *760Statutes § 136-131.1 (1993). Also attached to the letter was Exhibit B, a list of plaintiffs other billboards “required to be removed.”
On 22 November 1991, defendant notified plaintiff by letter that removal of those billboards located along Federal Aid Interstate and Federal Aid Primary Highways (Exhibit A) required compensation upon removal, pursuant to North Carolina General Statutes § 136-131.1, and that therefore, those signs would not have to be removed until defendant appropriated the money to pay compensation, or until the law changed to no longer require compensation. However, this letter again gave notice that the signs listed in Exhibit B had to be removed by 15 April 1992 if they were still in violation of the ordinance on that date.
By letter dated 22 April 1992, defendant notified plaintiff that they were still in violation of the zoning ordinance, and that criminal charges may be brought if plaintiff permitted the violation to continue for as long as ten (10) days after receiving the letter.
On 11 May 1992, plaintiff filed an action against defendant seeking damages, due to the enactment of this ordinance which regulated signs within the city. Defendant filed an answer moving to dismiss plaintiff’s motion for lack of subject matter jurisdiction and failure to exhaust administrative remedies, and to dismiss all claims for failure to state a claim upon which relief could be granted based upon the statute of limitations. The trial judge allowed defendant’s motion to dismiss pursuant to North Carolina General Statutes § 1A-1, Rule 12(b)(6) (1990) on statute of limitations grounds. From this dismissal, plaintiff appeals to our Court.
Plaintiff argues that its “inverse condemnation claim for the taking of its sign properties by enforcement of the Winston-Salem zoning ordinance is not barred by the applicable statute of limitations.” Specifically, plaintiff argues the date of “taking” should be the date the City required the removal of the signs, the last date of the amortization period, and that as a result, the statute of limitations should run from that date. Further, plaintiff argues that even if the “taking” occurred at some earlier date, the running of the statute of limitations does not begin to run until the date of completion of the “project.” For reasons which follow, we find that plaintiff’s argument fails.
As an initial matter, we note that zoning ordinances involving billboard removal after an amortization period have been held to *761be lawful and to not constitute a taking. See Givins v. Town of Nags Head, 58 N.C. App. 697, 294 S.E.2d 388, cert. denied and appeal dismissed by 307 N.C. 127, 297 S.E.2d 400 (1982), where our Court found that the town’s prohibition (with a five and one half year amortization period) of off-premise commercial signs, while permitting on-premise signs, did not violate equal protection. See also Summey Outdoor Advertising v. County of Henderson, 96 N.C. App. 533, 386 S.E.2d 439, disc. review denied, 326 N.C. 486, 392 S.E.2d 101 (1990); State v. Joyner, 286 N.C. 366, 211 S.E.2d 320, appeal dismissed by 422 U.S. 1002, 45 L.Ed.2d 666 (1975), where our Supreme Court found a zoning ordinance valid which provided for termination of certain non-conforming uses after an amortization period. Similarly, the enactment of the ordinance in the case sub judice does not constitute a taking.
Therefore, this case turns on a determination of the statute of limitations. We note that this issue was presented in a Fourth Circuit case arising out of Raleigh on facts quite similar to the facts in this appeal. In National Advertising Co. v. City of Raleigh, 947 F.2d 1158 (4th Cir. 1991), cert. denied by 118 L.Ed.2d 593 (1992), the plaintiff sign company brought suit against the city of Raleigh alleging that a city ordinance restricting off-premise outdoor advertising signs resulted in an unconstitutional taking of its property. The plaintiff argued that the trial court erred in finding that the cause of action accrued upon enactment of the ordinance in 1983, rather than when the amortization period expired. Although this case dealt with a 42 U.S.C. § 1983 action alleging an unconstitutional taking, the Court’s reasoning as to when the statute of limitations accrued is persuasive:
National [plaintiff sign company] contends that its 'cause of action did not accrue until the expiration of the 572 year amortization period . . . when it faced the City’s demand that the nonconforming signs be removed. Until then, National asserts, it suffered no actual injury because the . . . ordinance was neither applied nor enforced against it. . . .
National’s contentions miss the mark. Immediately upon enactment, the . . . ordinance interfered in a clear, concrete fashion with the property’s primary use. Thus, [on the date the ordinance was enacted] National’s signs became “nonconforming outdoor advertising signs.” ... The ordinance therefore interfered in a concrete fashion with National’s primary use *762of its existing signs by mandating that this use change or cease within five years.
Id. at 1163. We adopt the reasoning of the Court in National Advertising Co. and hold that plaintiff’s cause of action in the appeal before us accrued when the ordinance was adopted on 15 April 1985.
The applicable statute of limitations as to zoning ordinances is found in North Carolina General Statutes § 160A-364.1 (1987) which states “[a] cause of action as to the validity of any zoning ordinance, or amendment thereto, adopted under this Article or other applicable law shall accrue upon adoption of the ordinance, or amendment thereto, and shall be brought within nine months as provided in G.S. § 1-54.1.” Therefore, in the case at hand, we find the statute of limitations on this cause of action has run, and that the trial judge properly dismissed this case pursuant to North Carolina General Statutes § 1A-1, Rule 12(b)(6) on statute of limitations grounds.
We need not address plaintiff’s remaining arguments.
The decision of the trial court is affirmed.
