In this sign ordinance case, Plaintiff Crown Media appeals the district court’s order declaring that its constitutional challenges to Defendant Gwinnett County’s now repealed 1990 and 1999 sign ordinances are moot. This case involves a sign that Gwinnett County approved but now seeks to have removed. Crown Media sued to enjoin Gwinnett County from requiring it to take down its sign. After oral argument and review, we conclude that Crown Media’s complaint is not moot. Thus, we reverse and remand this case to the district court.
I. BACKGROUND
In this case, Crown Media challenges the constitutionality of Gwinnett County’s now repealed 1990 and 1999 sign ordinances. The constitutionality of the current sign ordinance, enacted on August 28, 2001, is not involved in this case. Instead, Gwinnett County contends, and the district court concluded, that the enactment of the 2001 ordinance caused Crown Media’s constitutional challenges to the repealed 1990 and 1999 ordinances to become moot.1 To answer this mootness issue, we first review the events surrounding Crown Media’s permits and erection of its sign.
A. 1990 Ordinance
On September 11, 1998, Crown Media applied to Gwinnett County for a sign permit and a building permit for the construction of a sign on a 3.3 acre tract located at 4431 Peachtree Industrial Boulevard, zoned “M-l” for light industrial. Gwin-nett County issued Crown Media both a sign permit and a building permit on September 17,1998.2
At the time of Crown Media’s application, Gwinnett County’s ordinance (the “1990 ordinance”) required this type of sign to be: (1) at least 300 feet from a residential zoning district and school, (2) at least seventy-five feet from a right-of-way, and (3) no more than forty feet in height. The dimensions in Crown Media’s plans submitted with its sign application complied with the 1990 ordinance. Thus, Crown Media applied for a sign and building permit to erect a sign whose dimensions complied with the 1990 ordinance.
After obtaining permits, Crown Media paid $100,000 to PBJ Development Company (“PBJ”) for the right to erect and maintain a sign on PBJ’s property. Crown Media paid $32,515 to an independent contractor who completed the sign in March 1999. The contractor, however, did not erect the sign in exact compliance with Crown Media’s plans. Specifically, the sign, as built, is: (1) seventeen and one-half feet closer than the approved placement to a residential zoning district of 300 feet; (2) closer than seventy-five feet to the nearest right-of-way; and (3) seven feet in excess of the approved height of *1320forty feet.3 Notwithstanding the sign’s non-adherence to the 1990 ordinance, the issued permits, and the plans on which the permits were based, Gwinnett County allowed and approved the sign through the required inspections, and Gwinnett County issued a certificate of occupancy and a certificate of completion of the sign on May 13, 1999. Crown Media then placed advertising on its sign.
B. 1999 Ordinance
After Gwinnett County issued the 1998 permits and 1999 certificates, Gwinnett County amended its sign ordinance on June 29, 1999 (the “1999 ordinance”). The required setback from the right-of-way and the height limitation remained the same in the 1990 and 1999 ordinances. The 1999 ordinance, however, increased the required setback distance for billboards from a residential zoning district, school, or daycare center from 300 feet to 500 feet.
The 1999 ordinance also changed an aspect of the permit process for billboards within the “M-l” zoning districts. The 1990 ordinance had provided that billboards may be permitted as “an allowed use” within the “M-l” districts. Gwinnett County, Ga., Ordinances art. XI, § 1113.1(1) (1990).4 The 1999 ordinance, however, provided that “[billboards may be permitted ... by special use permit within the M-l district.” Gwinnett County, Ga., Ordinances art. XI, § 1113.1(1) (1999).
C. Complaints About the Sign
Crown Media did not receive any complaints about its sign during the initial ten months after its May 13, 1999, completion. On March 15, 2000, however, Phyllis Hum-rich, the Gwinnett County Zoning Compliance Manager, sent Crown Media a letter alleging that “several violations exist concerning the installation, placement, and lighting of the billboard.”5 Although written in 2000, Humrich’s letter specifically noted that the sign violated the forty-foot height limitation, the 300 foot setback requirement, and the illumination regulations: all requirements of the 1990 ordinance in effect when the 1998 permits issued.6 Thus, Gwinnett County originally faulted Crown Media for not complying with the 1990 ordinance. Prior to receipt of Humrich’s March 15, 2000, letter, Crown Media believed that the contractor *1321constructed its sign in accordance with its plans, which complied with the 1990 ordinance.
D. May 19, 2000, Meeting
A meeting about the alleged violations occurred on May 19, 2000. Humrich informed Crown Media that the sign’s height should be reduced to forty feet and its head should be cantilevered or rotated so that all portions of the sign would be located at a minimum of 300 feet from any residential zoning district.7 According to Crown Media, Humrich further advised that these changes could be made under the existing sign and building permits issued in 1998, and requested evidence that the sign could be safely altered to cause it to be located at a minimum of 300 feet from a residential subdivision. Crown Media assured Humrich that it would comply with her requests.
Crown Media then gave Gwinnett County a June 12, 2000, letter from the sign builder stating (1) that the sign could be moved to conform with Gwinnett County’s requirements, and (2) that such construction could be completed in approximately three months.
E. July 6, 2000, Notice to Remove Sign
In response to the June 12, 2000, letter, Humrich sent Crown Media a July 6, 2000, notice stating that its sign violated Gwin-nett County’s sign ordinance and must be removed within thirty days to avoid further legal action. The notice stated that “the sign structure is in violation of the Gwinnett County Zoning Resolution Section 1113.1 and must be removed.” The notice did not specifically state whether Gwinnett County relied on a violation of the 1990 or 1999 ordinance or both in determining that the billboard must be removed.8
After receiving Gwinnett County’s July 6, 2000, notice, Crown Media appealed to the Gwinnett County Zoning Board of Appeals (“ZBA”). In that appeal, Crown Media claimed: (1) that Gwinnett County was impermissibly applying new zoning regulations enacted after the issuance of the permits and certificates of occupancy and completion; (2) that this was an illegal attempt to enforce a new law retroactively; (3) that the 1990 and 1999 ordinances were unconstitutional in any event; and (4) that Crown Media had a vested property right to maintain its sign. Crown Media asked the ZBA (1) to overturn the removal notice and (2) to order that Crown Media could complete construction of its sign in strict compliance with the 1990 ordinance in effect when its 1998 permits were issued.
*1322The ZBA denied Crown Media’s appeal on August 9, 2000.9 Crown Media appealed the ZBA’s decision to the Superior Court of Gwinnett County in an action styled Crown Media, LLC v. Gwinnett County, Ga., No. 00-A-8227-4 (Ga. Sup. Ct. filed Sept. 6, 2000). In that action, Crown Media claims that the 1990 and 1999 ordinances are unconstitutional and void, and that it has vested property rights in its sign. On March 4, 2002, the Gwin-nett County Superior Court stayed that action until this pending federal litigation concludes.
F. August 21, 2001, Application for Special Use Permit
While the state court action was pending, Crown Media applied for a special use permit for its sign on August 21, 2001. The 1999 ordinance added this special use permit requirement for billboards in “M-1” zoning areas.10 Crown Media initially sought variances under the 1999 ordinance for its sign, but was told by county officials that it must first obtain a “special use permit” under the 1999 ordinance, and then apply for variances.11 On November 27, 2001, the Gwinnett County Board of Commissioners held a public hearing at which Crown Media requested a special use permit with the intent to relocate its sign to a conforming location under the 1990 ordinance, a plan similar to that discussed with Humrich. The Board denied Crown Media a special use permit.
On the Board’s behalf, a Commissioner made these findings: (1) that there was no legitimate reason stated for the approval of the special use permit application; (2) that allowing Crown Media’s sign to remain would set an adverse precedent under the 1999 ordinance; (3) that the sign does not meet the 500 foot minimum setback from a residential zoning district or daycare center; (4) that the sign does not meet the minimum separation from another billboard; (5) that the sign adversely affects the visual quality and traffic safety along the Peachtree Industrial corridor; (6) that the sign violates policy LI.2 of the comprehensive plan land use element for light industrial areas; and (7) that the sign creates light problems.
Having been denied a special use permit under the 1999 ordinance, Crown Media contends that the 1999 ordinance, like the 1990 ordinance, is unconstitutional, and that thus no valid law precluded its sign when the permits were issued in 1998, when the sign was erected in 1999, when Gwinnett County issued its removal notice in 2000, or when Crown Media applied for a special use permit in 2001.
G. 2001 Ordinance
On August 28, 2001, Gwinnett County adopted a new sign ordinance (the “2001 ordinance”) that altered significantly the substance of the 1999 ordinance to address constitutional concerns.12 The 2001 ordi*1323nance, however, kept in place the 500-foot setback restriction from a residential zoning district and daycare center, the seventy-five foot setback restriction from a right-of-way, and the forty foot height limitation. Although Crown Media does not challenge the constitutionality of the 2001 ordinance, Gwinnett County contends that its enactment moots Crown Media’s constitutional challenges to the 1990 and 1999 ordinances.
H. Procedural History
On December 20, 2001, Crown Media filed this federal suit, seeking declaratory relief that the 1990 and 1999 ordinances are unconstitutional and injunctive relief against Gwinnett County’s continued enforcement of the height and location restrictions in these ordinances.13 Crown Media seeks to keep its sign in place through injunctive relief and does not seek damages.14
On cross-motions for summary judgment, the district court addressed Crown Media’s claims under the 1990 and 1999 ordinances and granted judgment in favor of Gwinnett County. The district court concluded that Crown Media’s constitutional challenge to the 1999 ordinance was moot because the 2001 ordinance removed all of the alleged constitutional violations in the 1999 ordinance. The district court also concluded that there was no reasonable expectation that the challenged practices will resume. The district court further determined that Crown Media did not possess any vested property rights in its sign or its permits issued under the 1990 ordinance.15 This appeal followed.
II. STANDARD OF REVIEW
This Court reviews a district court’s grant of summary judgment de novo. Cafe Erotica of Fla., Inc. v. St. Johns County, 360 F.3d 1274, 1281 (11th Cir.2004). This Court reviews questions of mootness de novo. Christian Coalition of Ala. v. Cole, 355 F.3d 1288, 1290 (11th Cir.2004).
*1324III. DISCUSSION
In this appeal, the only issue is whether Crown Media’s constitutional challenges to the 1990 and 1999 ordinances are moot due to the enactment of the 2001 ordinance. To answer that question, we review (1) some general mootness principles and (2) Georgia law regarding vested property rights. We then apply those legal principles to Crown Media’s claims.
A. Mootness Principles
“The Constitution limits the jurisdiction of the federal courts to actual cases and controversies. To satisfy the case or controversy requirement of Article III, a plaintiff must have suffered some actual injury that can be remedied or redressed by a favorable judicial decision.” Nat’l Adver. Co. v. City of Ft. Lauderdale, 934 F.2d 283, 285-86 (11th Cir.1991) (internal citation omitted). A case is moot “ ‘when the issues presented are no longer “live” or the parties lack a legally cognizable interest in the outcome.’ ” Granite State Outdoor Adver., Inc. v. City of Clearwater, Fla., 351 F.3d 1112, 1119 (11th Cir.2003) (quoting Powell v. McCormack, 395 U.S. 486, 496, 89 S.Ct. 1944, 1951, 23 L.Ed.2d 491 (1969)). “Put another way, [a] case is moot when it no longer presents a live controversy with respect to which the court can give meaningful relief.” 31 Foster Children v. Bush, 329 F.3d 1255, 1263 (11th Cir.) (internal quotation marks and citation omitted), cert. denied, — U.S. -, 124 S.Ct. 483, 157 L.Ed.2d 376 (2003).
“[Mjootness is a' justiciability doctrine that must be satisfied before we may decide a case.” Granite State Outdoor Adver., 351 F.3d at 1119. “ ‘Because the judiciary is unelected and unrepresentative, the Article III case-or-controversy limitation, as embodied in [the] justiciability doctrine, presents an important restriction on the power of the federal courts.’ ” Coral Springs St. Sys., Inc. v. City of Sunrise, 371 F.3d 1320, 1327 (11th Cir.2004) (quoting Socialist Workers Party v. Leahy, 145 F.3d 1240, 1244 (11th Cir.1998)).
“Generally, a challenge to the constitutionality of a statute is mooted by the repeal of the statute.” Coral Springs, 371 F.3d at 1328-32 (surveying our mootness precedents). When a party challenges a law as unconstitutional and seeks only declaratory and prospective injunctive relief, a “ ‘superseding statute or regulation moots a case ... to the extent that it removes challenged features of the prior law.’ ” Coalition for the Abolition of Marijuana Prohibition v. City of Atlanta, 219 F.3d 1301, 1310 (11th Cir.2000) (quoting Naturist Soc’y, Inc. v. Fillyaw, 958 F.2d 1515, 1520 (11th Cir.1992)). “ ‘To the extent that those features remain in place, and changes in the law have not so fundamentally altered the statutory framework as to render the original controversy a mere abstraction, the case [is] not moot.’ ” Coalition for the Abolition of Marijuana Prohibition, 219 F.3d at 1310 (quoting Naturist Soc’y, Inc., 958 F.2d at 1520).16
In addition, for the repeal of a statute to moot a challenge to that statute, the governmental defendant must show that there is no reasonable likelihood that the repealed statute or challenged practices would be reinstated. Coral Springs, 371 F.3d at 1328; Christian Coalition of Ala., 355 F.3d at 1291; Jews for Jesus, Inc. v. Hillsborourgh County Aviation Auth., 162 F.3d 627, 629 (11th Cir.1998). *1325Further, when a plaintiff requests damages, as opposed to only declaratory or injunctive relief, changes to or repeal of the challenged ordinance may not necessarily moot the plaintiffs constitutional challenge to that ordinance. See Granite State Outdoor- Adver., 351 F.3d at 1119 (concluding that even though sign ordinance was repealed, constitutional challenge was not moot because plaintiff requested damages).17
In this case, Crown Media does not request damages and does not contend that Gwinnett County may reinstate the repealed 1990 and 1999 ordinances. According to Crown Media, what makes this case justiciable is its vested property rights in its sign and permits. Specifically, Crown Media says that its challenges to these old ordinances are not moot because under Georgia law, its property rights in its sign and permits vested prior to the enactment of the 2001 ordinance, and that therefore subsequent changes to the old 1990 and 1999 ordinances do not affect whether it is entitled to its preexisting sign and permits.
In Coral Springs, 371 F.3d 1320 (11th Cir.2004), this Court recognized that a party’s vested property rights constitute an enforceable entitlement to a permit or a sign unaffected by subsequent changes in sign ordinances and may keep a constitutional challenge to a repealed sign ordinance from becoming moot under federal law. Id. at 1333. Further, the parties here do not dispute that a vested property right to a pre-existing permit or sign is a cognizable interest that may keep a constitutional challenge to a subsequently repealed ordinance justiciable. Instead, they dispute whether Crown Media has any such vested property rights.
Whether a plaintiff has obtained vested property rights in a sign or permit is a question of state law. Id. at 1333-34 (surveying Florida law and determining that plaintiff did not have a vested property right to the issuance of a sign permit under Florida law);18 Nat’l Adver. Co., 934 F.2d at 286 (stating that on remand, district court must “decide whether National has vested rights under Florida law to build billboards on its property”). Thus, to determine whether Crown Media has vested property fights in its sign and permits, we must examine Georgia law and then apply it to Crown Media’s claims.
B. Georgia Law
1. Issued Permits
If a property owner obtains a valid sign or building permit authorizing a particular land use under an existing zoning ordinance, Georgia courts have concluded that property rights vest when a permit is actually issued for a particular land use and that a later, new zoning ordinance prohibiting that land use is not enforceable against the property owner. WMM Props., Inc. v. Cobb County, 255 Ga. 436, 339 S.E.2d 252, 254 (1986); Schul-*1326man v. Fulton County, 249 Ga. 852, 295 S.E.2d 102, 103 (1982); Clark v. Int’l Horizons, Inc., 243 Ga. 63, 252 S.E.2d 488, 490 (1979); Keenan v. Acker, 226 Ga. 896, 178 S.E.2d 196, 197-98 (1970); see Craig v. City of Lilbum, 226 Ga. 679, 177 S.E.2d 75, 76 (1970).19 “Once a building permit has issued, a landowner has the right to develop the property pursuant to that permit.” WMM Props., 339 S.E.2d at 254. Further, under Georgia law the landowner has such vested rights in an issued permit for a particular land use “notwithstanding a zoning or regulatory change subsequent to the issuance of the building permit, and notwithstanding the fact that there has been no substantial expenditure of funds in reliance upon the building permit.” Id. In addition, the landowner retains that vested right to develop the property pursuant to an issued permit “during its term or for a reasonable time after its issuance if no term is specified.” Id.20
2. Structure Built in Compliance with Permit
Georgia courts have also determined that the issuance of a permit vests a right in the permit holder only to build in accordance with the requirements in a valid permit or in a valid zoning ordinance. In Jackson v. Delk, 257 Ga. 541, 361 S.E.2d 370 (1987), the Georgia Supreme Court stated that “the issuance of a building permit, as well as various other forms of administrative approval, vests the right of the permittee to develop his or her property in accordance with existing zoning or regulatory laws.” Id. at 372; see WMM Props., 339 S.E.2d at 254 (stating that “[o]nce a building permit has issued, a landowner has a right to develop the property pursuant to that permit”); Gifford-Hill & Co. v. Harrison, 229 Ga. 260, 191 S.E.2d 85, 89 (1972) (stating that “an applicant must thereafter comply with all reasonable conditions and requirements imposed upon the use of the land”).
In addition, the Georgia Supreme Court has concluded that if a Georgia property owner builds its structure in accordance with its valid permits and the relevant ordinances, the property owner maintains a vested property right in its pre-existing structure, despite the subsequent enactment of an ordinance prohibiting the structure or previously permitted use. *1327See Lamar Adver. of S. Ga., Inc. v. City of Albany, 260 Ga. 46, 389 S.E.2d 216, 217 (1990) (concluding plaintiff had vested property right to erect sign after obtaining permit to build, despite subsequent change in sign ordinance prohibiting permitted signs); WMM Props., 339 S.E.2d at 254; Craig, 177 S.E.2d at 76.
3. Non-Compliant Structure and Valid Ordinance
Georgia case law also addresses what happens when a property owner is issued a permit but does not construct the structure in accordance with that permit. Under Georgia law, a property owner does not obtain vested property rights in a non-compliant structure, and the county may enforce pre-existing requirements in a valid permit or zoning ordinance and require, in some circumstances, that the non-compliant structure be taken down or moved to comply with the permit. See Dep’t of Transp. v. Shiflett, 251 Ga. 873, 310 S.E.2d 509, 512 (1984) (remove totally unauthorized sign); Gray v. DeKalb County, 230 Ga. 95, 195 S.E.2d 914, 916 (1973) (move partially completed house to proper setback, not destroy it); DeKalb County v. DRS Invs., Inc., 260 Ga.App. 225, 581 S.E.2d 573, 575-76 (2003) (remove sign in light of knowing and gross violations of ordinance).
Although broadly speaking a property owner does not acquire vested property rights in its non-compliant structure, the property owner retains vested property rights to build its structure in accordance with the issued permit “during its term or for a reasonable time after its issuance if no term is specified.” WMM Props., 339 S.E.2d at 254; DRS Invs., 581 S.E.2d at 575;21 see O.C.G.A. § 36-74-23(b) (“[I]f a violation of any code or ordinance is found, the code inspector shall ... give him or her a reasonable time to correct the violation.”); Tilley Props., Inc. v. Bartow County, 261 Ga. 153, 401 S.E.2d 527, 529 (1991) (“A ‘county has the duty and obligation to work with property owners to allow them the highest and best use of their property .... ’ ’’Xquoting DeKalb County v. Flynn, 243 Ga. 679, 256 S.E.2d 362, 364 (1979)). Accordingly, under Georgia law, a property owner may attempt to bring its non-compliant structure into compliance during the permit time or for a reasonable time if no express time limit is in the permit.22
This Georgia case law involves permits issued pursuant to valid ordinances. The difficult question is what happens when a property owner does not construct its structure in accordance with setback and height restrictions in an issued sign permit but the ordinance requiring those restrictions is unconstitutional or otherwise invalid. We turn to that question.
*1328 k- Nowr-Complimt Structure and Unconstitutional Ordinance
In determining whether a property owner is entitled to a particular land use, Georgia courts at times have assessed the validity or constitutionality of the relevant zoning ordinance restricting the sought-after land use. For example, in Tilley Props., Inc. v. Bartow County, 261 Ga. 153, 401 S.E.2d 527, 529 (1991), the Georgia Supreme Court declared an agricultural zoning ordinance void and then stated that “[w]here ... there is no valid restriction on the property,” the property owner “has the right under the law to use the property as it so desires.” 401 S.E.2d at 529.23 In Tilley, after declaring the zoning ordinance void, the Georgia Supreme Court granted a writ of mandamus directing the county to issue the property owner a land use certificate, a required first step for a surface mining permit. Id.
Sikes v. Pierce, 212 Ga. 567, 94 S.E.2d 427 (1956), provides an earlier example of a case in which the Georgia Supreme Court examined the validity of an ordinance to determine whether a property owner was entitled to the issuance of a permit for a particular land use. Id. at 429. In Sikes, the property owner applied for and was denied a building permit to construct a gasoline station on the grounds that the property was zoned only for residential purposes. Id. at 428. The Georgia Supreme Court determined that the charter of the municipality, which authorized the city to adopt zoning ordinances, and the zoning ordinances adopted under that charter violated interested property owners’ due process rights and were “null and void.” Id. at 429. In concluding that the property owners were entitled to a building permit, the Georgia Supreme Court stated that, “[i]n the absence of valid zoning regulations or restrictive covenants to the contrary, the right to use one’s property for a lawful business purpose is a right inherent in the ownership of the property, and is protected by law.” Id. at 428 (citations omitted).24
Further, under Georgia law even if one particular ordinance may be invalid or unconstitutional, a landowner still would have to comply with all other valid, relevant ordinances and regulations. See Butts County v. Pine Ridge Recycling, Inc., 213 Ga.App. 510, 445 S.E.2d 294, 297 (1994) (requiring company to comply with other valid restrictions even though there *1329was no valid county solid waste management plan); Cannon v. Clayton County, 255 Ga. 63, 335 S.E.2d 294, 295 (1985) (stating that after an applicant applies for authorization to use land for a particular purpose, the applicant “must thereafter comply with all reasonable conditions and requirements imposed upon the use of the land” (quoting Giffordr-Hill & Co., 191 S.E.2d at 89)).
Having discussed applicable Georgia law regarding permits, we now apply it to Crown Media’s claims.
C. Crown Media’s 1998 Permits
As recounted earlier, Crown Media was issued sign and building permits by Gwinnett County in 1998. In this case there is no contention by Gwinnett County that these permits issued to Crown Media are invalid. Accordingly, we examine this case as one in which the property owner has been issued valid permits for a permissible land use — erection of a sign — -under applicable laws and as one in which the merits issue is over whether Gwinnett County can require Crown Media to take down its sign for non-compliance with certain setback and height restrictions in the 1990 ordinance and in its permits stemming from the 1990 ordinance.
We first conclude that under Georgia law Crown Media had vested property rights in its permits. If Crown Media’s sign had been built in compliance with the restrictions in the 1990 ordinance and its permits, this case would be simple. Crown Media’s property rights in its sign would have vested under Georgia law and any subsequently enacted sign ordinance (such as the 1999 ordinance containing different setback restrictions) would be unenforceable against Crown Media’s pre-existing, legally constructed sign, and those vested property rights would make Crown Media’s challenge to the 1990 ordinance justi-ciable.
The difficulty for Crown Media is that its sign complied almost, but not fully, with the restrictions in the 1990 ordinance and its permits. Thus, if the 1990 ordinance is constitutional, Crown Media seemingly has no vested property right in its sign under Georgia law to the extent the sign was not in compliance with the 1990 ordinance and its permits. But under Georgia law Crown Media would have, and should have been given by Gwinnett County, the permitted time or a reasonable time to bring its sign into compliance with its permits (in which Crown Media did have vested property rights). This reasonable time-to-comply was especially relevant here where Crown Media had completed its sign and Gwinnett County approved the sign “as-built”, issued certificates of occupancy, and did not complain about the sign until ten months after completion.25
Moreover, if the 1990 ordinance is unconstitutional, Gwinnett County cannot rely, as it does, on the 1990 ordinance to require Crown Media to remove its sign. *1330As of this juncture, Gwinnett County has identified no other restrictions regarding sign size or location in existence at the time Crown Media applied for its permits and erected its sign. See Tilley, 401 S.E.2d at 529; Sikes, 94 S.E.2d at 429. Further, if the 1990 ordinance is unconstitutional and if, as Crown Media claims, the restrictions in Crown Media’s sign and building permits stem from and depend on that 1990 ordinance, then under Georgia law the restrictions in Crown Media’s permits would be void and unenforceable as well. This observation illustrates that the existence and scope of Crown Media’s property rights in its permits and erected sign under state law and the extent to which they vested prior to the enactment of the 2001 ordinance cannot be fully ascertained until the constitutionality of the 1990 ordinance is determined. Therefore, we conclude that Crown Media’s challenge to the constitutionality of the 1990 ordinance is not moot.
D. 1999 Ordinance
We recognize that if the 1990 ordinance is unconstitutional, this may resolve the parties’ dispute over Crown Media’s erected sign without any need to determine the constitutionality of the 1999 ordinance. Nonetheless, this appeal is also about Crown Media’s constitutional challenge to the 1999 ordinance, and we conclude that issue is also not moot. After construction of Crown Media’s sign and after Gwinnett County notified Crown Media to remove its sign, Crown Media applied for a special use permit for its preexisting sign under the 1999 ordinance. Gwinnett County denied Crown Media a special use permit primarily because its pre-existing sign did not comply with the requirements in the 1999 ordinance, such as the increased 500-foot setback from a residential zoning district, and because allowing Crown Media’s sign to remain would set an adverse precedent under the 1999 ordinance.
If the 1999 ordinance was unconstitutional, however, then Gwinnett County’s new special use permit requirement and its new setback restrictions would be null and void and not enforceable against Crown Media’s pre-existing, permitted sign. More important, the lack of a special use permit and non-compliance with the 1999 ordinance could be no basis for Gwinnett County’s ordering Crown Media to remove its pre-existing sign. Thus, the adoption of the 2001 ordinance did not make Crown Media’s constitutional challenge to the 1999 ordinance moot.26
IV. CONCLUSION
For all the above reasons, we conclude that, given the particular factual circumstances of this case, Crown Media’s constitutional challenges to the 1990 and the 1999 ordinances are not moot. In reaching this conclusion, we do not say or imply anything about the merits of this case because our only role at this juncture is to decide the single issue of mootness in this appeal. Accordingly, we reverse and vacate the district court’s order dismissing Crown Media’s complaint as moot, and remand this case for further proceedings in the district court.
