OPINION
Appellant National Advertising Company commenced this action in April 1989 under 42 U.S.C. § 1983 alleging that a 1983 ordinance adopted by the City of Raleigh, North Carolina, restricting off-premise outdoor advertising signs, violated the First and Fourteenth Amendments and also resulted in a taking without just compensation in violation of the Fifth and Fourteenth Amendments. The district court found that National’s suit was barred by North Carolina’s three-year limitations period set forth in G.S.N.C. § 1-52(2). On appeal, National contends that it suffered no injury from the ordinance, and hence no cause of action accrued, until a five-and-one-half (5V2) year grace period provided in the ordinance for nonconforming signs expired. National also contends that its action is timely because the ordinance constitutes a “continuing” constitutional violation. The district court rejected National’s contentions. Finding no error below, we affirm.
I.
On October 18, 1983, the Raleigh city council adopted Ordinance No. 210 TC 198 (“the 1983 ordinance” or “the ordinance”), which by its terms became effective October 23, 1983. 1 This ordinance amended a 1979 ordinance that established zoning regulations for signs in Raleigh. The 1979 ordinance allowed “on-premise” signs, defined as signs located on the premises which “direct[] attention to a business, profession, commodity, service, or entertainment conducted, offered, sold, manu- *1161 factored, or provided at a location on the premises where the sign is located or to which it is affixed,” and permitted “off-premise” signs (or “non-point-of-sale” signs) and special category signs, including political signs, real estate signs and governmental and public purpose signs, in certain areas of Raleigh.
The 1983 ordinance modified the 1979 ordinance, inter alia, by reducing the size of permissible off-premise signs from 672 square feet to 150 square feet for signs facing streets with four or more traffic lanes, and to 75 square feet for signs facing streets with fewer than four traffic lanes. A further modification confined the location of such signs to so-called “industrial zones” as defined in the ordinance. Existing signs larger than the specified dimensions were declared nonconforming uses. Furthermore, the. 1983 ordinance prohibited the construction of any new nonconforming signs and, except for ordinary maintenance and poster panel replacements, it also barred any structural alteration, reconstruction, or other material change to existing nonconforming signs unless the signs and their entire structures were brought into conformity with the 1983 ordinance. But existing nonconforming signs were not immediately banned. Rather, they enjoyed a 5V2 year grace period beginning October 23, 1983. At the end of this period nonconforming signs were required to be removed, unless they fell within a state law exception for signs located adjacent to highways on the National System of Interstate and Defense Highways or on the Federal-Aid Primary Highway system. The 5V2 year grace period (referred to in the ordinance as an “amortization” period) was in lieu of any other form of compensation.
National, a national advertising company, owns approximately thirty-six billboards in Raleigh. Sixteen of these billboards are located on federal highway systems and hence are exempted from the 1983 ordinance. National filed its complaint on April 28, 1989, more than three years after adoption of the 1983 ordinance and approximately one-month after expiration of the 5V2 year amortization period. Raleigh responded with.a motion for summary judgment pursuant to Rule 56, Fed. R.Civ.P., contending that the action was barred either by G.S.N.C. § 1-54.1, which establishes a nine-month limitation period for “actions contesting the validity of any zoning ordinance or amendment thereto,” or by G.S.N.C. § 1-52(2), which establishes a three-year limitations period for lawsuits based on “liability created by statute, either state or federal.” The district court determined that the latter statute applied and barred National’s suit. On appeal, National concedes that § 1-52(2) establishes the applicable limitations period. It contends, however, that it was not injured by the 1983 ordinance until the 5V2 year amortization period for nonconforming signs expired and it was forced to remove its signs or contest the validity of the ordinance. Accordingly, National argues that the district court erred in finding that the cause of action accrued upon enactment of the ordinance in October 1983. Instead, National contends the cause of action did not accrue until either the expiration of the amortization period or, at the earliest, January 6, 1989, the date it received a notification letter from Raleigh demanding the removal of its nonconforming billboards by April 1989. Alternatively, National claims that the 1983 ordinance created a continuing constitutional violation and therefore National’s action is timely. We review these claims seriatim.
II.
Because there is no.federal statute of limitations applicable to suits under § 1983, “it is the rule that the applicable ‘provision limiting the time in which an action [under § 1983] must be brought, must be borrowed from the analogous state statute of limitations.’ ”
Bireline v. Seagondollar,
The selection of the appropriate statutory limitations period is only the first step in the analysis. There remains the question of when National’s cause of action accrued. While the statutory limitations period for § 1983 actions is borrowed from state law, “[t]he time of accrual of a civil rights action is a question of federal law.”
Id.
at 50;
Campbell v. Haverhill,
The basis of a takings claim is the assertion that a regulation’s “interference with appellants’ property is of such magnitude that ‘there must be an exercise of eminent domain and compensation to sustain [it].’ ”
Penn Central Transportation Co. v. City of New York,
National contends that its cause of action did not accrue until the expiration of the 5V2 year amortization period in April 1989, when it faced the City’s demand that the nonconforming signs be removed. Until then, National asserts, it suffered no actual injury because the 1983 ordinance was neither applied nor enforced against it. Given this, National contends that no “as applied” challenge to the ordinance was possible before April 1989; at best only a facial challenge to the ordinance’s validity was possible prior to April 1989. 4
National’s contentions miss the mark. Immediately upon enactment, the 1983 ordinance interfered in a clear, concrete fashion with the property’s primary use. Thus, on October 23, 1983, National’s signs became “nonconforming outdoor advertising signs.” As such, those signs became immediately subject to the restriction that “[a]ll nonconforming outdoor advertising signs shall be discontinued or made conforming (amortized) within five and one-half (6%) years from the date of this ordi-nance_” The ordinance therefore interfered in a concrete fashion with National’s primary use of its existing signs by mandating that this use change or cease within five years.
Moreover, National suffered actual, concrete injury on October 23, 1983. On that date, the useful lives of National’s nonconforming signs were shortened from 30 years
5
to 5V2 years. Thus, the present value of the nonconforming signs was re
*1164
duced accordingly. Had National sought to sell its nonconforming Raleigh signs between October 1983 and April 1989, a buyer would have discounted the value of these signs to account for their shortened life. Hence, on the date of the ordinance’s enactment, there was both substantial interference with the property’s primary use so as to affect distinct investment-backed expectations and also actual concrete injury accompanying that interference. Whether that interference was of such magnitude as to constitute an actual “taking” could have been determined upon the enactment of the statute in 1983. We do not reach the issue here of whether the interference “was of such a magnitude that ‘there must be an exercise of eminent domain and compensation to sustain [it].’ ”
Penn Central,
National’s cited authority is not to the contrary. This authority emphasizes that takings challenges normally focus on a statute’s application to specific property, rather than attacking a statute or ordinance on its face.
See, e.g., Keystone Bituminous Coal Ass’n v. DeBenedictis,
These “ad hoc, factual inquiries” must be conducted with respect to specific property, and the particular estimates of economic impact and ultimate valuation relevant in the unique circumstances.
Hodel,
Decisions holding takings challenges to be “premature” because of the availability of administrative compensation and review mechanisms 12 are also inappo-site. The 1983 ordinance did not establish any variance or administrative review procedures through which sign owners might obtain relief. Instead, it provided for immediate compliance without exception. 13 Moreover, the ordinance provided for no compensation other than what it referred to as “amortization.” It stated that “amortization of nonconforming outdoor signs, in contrast to grandfathering these noncon-formities, will eliminate the excessive number and amount of outdoor advertising signs and signage.” Hence, just as there are no variance or compensation procedures which National must exhaust now before bringing its suit, none existed in 1983 to prevent ripeness of its suit.
Finally, National is mistaken in relying on cases holding that no taking occurs where regulations permit the current use of property to continue unhindered.
See Penn Central Transportation Co. v. City of New York,
In sum, when enacted the 1983 ordinance interfered in concrete ways with National’s primary use of specific property — thirty-six signs. The district court therefore did not err in determining that National’s takings cause of action arose in October 1983.
III.
National’s second appeal ground is that its suit is timely because the 1983 ordinance created a continuing constitutional violation. This ground, too, fails because this is not a continuing violation case. As has been observed many times: “A continuing violation is occasioned by continual unlawful acts, not continual ill effects from an original violation.”
Ward v. Caulk,
In general, “[t]o establish a continuing violation ... the plaintiff must establish that the unconstitutional or illegal act was a ... fixed and continuing practice.”
Perez v. Laredo Junior College,
706
*1167
F.2d 731, 733 (5th Cir.1983),
cert. denied,
If the discrimination alleged is a single act, the statute begins to run at the time of the act. If, on the other hand, the statutory violation does not occur at a single moment but in a series of separate acts and if the same alleged violation was committed at the time of each act, then the limitations period begins anew with each violation and only those violations preceding the filing of the complaint by the full limitations period are foreclosed.
Id. at 733-34 (footnotes omitted).
With respect to statutory or regulatory challenges, we have previously found a continuing violation where regulations continued to be applied to persons within the statutory limitations period.
Virginia Hospital Ass’n v. Baliles,
National’s claimed harm is that the 1983 ordinance restricted the use of its property without providing just compensation. The challenged municipal action, however, does not amount to a continuing wrong. The restriction on use and the economic loss of which National complains occurred upon enactment of the ordinance. No City action since then has added to National’s alleged injury or otherwise constituted a taking. Seeking to avoid this conclusion, National points to a January 1989 letter from Raleigh, informing it that its nonconforming signs would have to be removed by April 1989, as a later wrongful act committed by the City within three years of National’s suit. This argument misses the mark. The letter was not a new wrongful act, but merely a reminder of the restriction placed on National’s signs in 1983. It caused National no additional injury, and is not itself the source of the alleged taking. The fact that National’s signs ultimately were required to be removed or brought into conformity by April 1989 was one of the
effects
of their being deemed nonconforming upon enactment of the ordinance, not a separate violation.
*1168
Compare Delaware State College v. Ricks,
Finally, an examination of the “particular policies of the statute of limitations in question,”
Id.
at 107, supports the conclusion that no unfairness results from finding that the continuing wrong exception is inapplicable here. National was aware of the 1983 ordinance from at least the date of its enactment. National participated in rulemaking proceedings prior to adoption of the ordinance and clearly knew of its terms in 1983; moreover, National was required by law to be cognizant of the numerous restrictions placed on its signs upon the ordinance’s enactment. Upon the adoption of the ordinance, National was in a position to challenge it. “[A] ‘continuing wrong’ theory should not provide a means of relieving plaintiff from its duty of reasonable diligence in pursuing its claims.”
Ocean Acres,
IV.
National contended before the district court that the 1983 ordinance on its face violates the First Amendment because it (i) restricts speech without promoting a legitimate government interest, (ii) is over-broad, and (iii) is unconstitutionally vague. The district court specifically addressed only the first of these claims, and found that it was barred by the three-year statute of limitations because “plaintiff had reason to know of this alleged injury at the time the ordinance became effective.” Because it is doubtful that an ordinance facially offensive to the First Amendment can be insulated from challenge by a statutory limitations period, and since National’s First Amendment claims raise purely legal issues which are well-settled, we review National’s First Amendment claims on the merits.
National contends that the 1983 ordinance does not substantially advance a legitimate state interest and is overbroad because the effect of its size limitations will be to eliminate all outdoor off-premise advertising. Settled authority compels rejection of these claims. In
Major Media of the Southeast v. City of Raleigh,
National’s remaining First Amendment claim is that the ordinance is unconstitutionally vague because in certain limited instances it requires city officials to determine whether the contents of an advertisement are “commercial” or “non-commercial.”
15
National contends that since the ordinance contains no definition of “commercial” or “non-commercial,” insufficient guidance is given city officials. We rejected this precise contention in
Major Media of the Southeast v. City of Raleigh,
Although an occasional marginal case might arise raising the question of whether on the particular facts the definition of commercial speech would be correct, such an infrequent possibility should not itself justify a generalized charge that the ordinance itself is vague, given the guidance afforded by the court decisions in the area.
Id. at 1272-73. We find no reason to depart from our previous holding. 16 In sum, we reject National’s First Amendment claims on the merits.
Accordingly, we affirm the decision of the district court granting summary judgment to Raleigh.
AFFIRMED.
Notes
. A detailed description of this ordinance appears in this Court's opinion in
Major Media of the Southeast, Inc. v. City of Raleigh,
.
In concluding that G.S.N.C. § 1-52(2) provides the applicable limitations period, the parties rely on past decisions of this Court.
See Bireline,
where state law provides multiple statutes of limitations for personal injury actions, courts considering § 1983 claims should borrow the general or residual statute for personal injury actions.
Owens v. Okure,
. In
Esposito,
this Court concluded that a South Carolina statute effected no taking where it merely restricted the location for the rebuilding of beach cottages destroyed by natural causes or fire.
. National cites no decisions directly on point to support these contentions. Instead, it relies on general propositions to the effect (1) that “petitioners ... face an uphill battle in making a facial [takings] attack,”
Keystone Bituminous Coal Ass’n v. DeBenedictis,
. National alleges in its complaint that its existing signs have remaining useful lives of up to 30 years.
.To determine whether the interference was so onerous as to constitute a taking requires a detailed analysis similar to that described in
Naegele Outdoor Advertising, Inc. v. City of Durham,
. The ordinance stated in relevant part:
WHEREAS, North Carolina General Statutes 136-131.1 prohibits the regulatory amortization of outdoor advertising signs adjacent to highways on the National System of Interstate Defense Highways and the Federal-aid Primary Highway System and that the gradual attrition of these outdoor advertising signs provides suppliers and consumers of outdoor advertising an abundant reservoir of locations within the Raleigh market....
BE IT ORDAINED BY THE CITY COUNCIL OF RALEIGH, NORTH CAROLINA that:
All nonconforming outdoor advertising signs shall be discontinued or made conforming (amortized) within five and one-half (5lA) years from the effective date of this ordinance ([October 23, 1983]), unless explicitly prohibited by State Statute.
(Emphasis added).
. The sixteen signs located along federal highway systems, while exempt from the removal requirement, still remained “nonconforming uses” subject to the ordinance’s other restrictions, such as the prohibitions on reconstructing
*1165
damaged nonconforming signs, moving existing nonconforming signs to new locations on their lots, or building more such signs along the federal highway systems.
Compare National Advertising Co. v. Bradshaw,
. A facial takings attack is a claim that the “mere enactment” of a statute constitutes a taking.
Hodel,
. Both
Hodel
and
Keystone,
for example, involved facial attacks on expansive regulatory programs affecting mining properties
in general,
but not specifically identified properties. Moreover, because owners might win variances or exemptions from the program, a challenge of the program’s application to specific property was not yet ripe. In
Hodel,
the Virginia Surface Mining and Reclamation Association brought a facial takings challenge against interim regulations promulgated by the Department of the Interior pursuant to the Surface Mining Control and Reclamation Act of 1977, 91 Stat. 447, 30 U.S.C. § 1201
et seq.
(1976 ed., Supp. III). The regulations,
inter alia,
required "steep slope” surface mine operators to return a mining site to its "approximate original contour.” A mine operator could obtain a variance from this requirement, however, by showing that a site’s new condition would allow a postreclamation economic or public use equal or better than what would otherwise be possible.
Hodel,
.Consistent with this conclusion are those decisions involving advertisers that attacked sign ordinances on takings grounds prior to the expiration of amortization periods. In none of those decisions was the attack challenged as premature.
See, e.g., Major Media of the Southeast, Inc. v. City of Raleigh,
.
See, e.g., MacDonald, Sommer & Frates v. Yolo County, 477
U.S. at 351-52,
. The ordinance stated: "All outdoor advertising signs shall be consistent with all definitions and shall comply with all standards and regulations of this code,” and "All nonconforming outdoor advertising signs shall be discontinued or made conforming (amortized) within five and one-half (5!/2) years ... unless explicitly prohibited by State Statute.” (Emphasis added.)
. The ordinance states that its purpose is to "enhance property values traffic safety, and [the] community appearance" of Raleigh.
. Raleigh’s ordinance, as amended on December 4, 1984 by Ordinance 450 TC 228, states: "Any sign authorized in this chapter is allowed to contain non-commercial copy in lieu of any other copy." As we noted
Major Media of the Southeast v. City of Raleigh,
. We also note that even if the specific provisions of the Raleigh ordinance that require inspectors to consider the content of an advertisement were held invalid, the size limitations on off-premise advertising, which are the provisions that affect National, would remain in force. See Raleigh City Code § 14-1004 (discussing severability of "sections, paragraphs, sentences, clauses and phrases of this Code").
