MARCUS, Circuit Judge: At issue in this case is the constitutionality of the City of Neptune Beach’s sign code. Appellant Solantic, LLC (“Solantic”) argues that the sign code violates the First Amendment in at least two ways: first, it exempts from regulation certain categories of signs based on their content, without compelling justification for the disparate treatment; and second, it contains no time limits for permitting decisions. We agree with Solantic, and hold the sign code unconstitutional on both grounds. I. Solantic is a business operating emergency medical care facilities in various locations, including the City of Neptune Beach (“the City” or “Neptune Beach”). In April 2003, Solantic installed in front of its Neptune Beach facility a large “Electronic Variable Message Center” (EVMC) sign. A videotape showing the sign was viewed by the district court and is part of the record. The district court describes the EVMC sign as sitting in the middle of a pole, approximately 10 to 12 feet above the ground, and situated below a larger blue sign displaying Solantic’s business name. Solantic states that the EVMC sign “was used for, and is intended to be used for, commercial messages, i.e. to identify Solantic’s business and to convey information about its products and services, and for noncommercial messages, i.e. to promote social and health ideas and causes.” Br. at 4. As the City describes it, Solantic’s EVMC sign conveyed “electronically lit messages that flashed, blinked and scrolled across the surface of the sign.” Br. at 1. Prior to erecting the sign, Solantic obtained an electrical permit from the City to operate the sign. Solantic did not, however, submit to the City a sign application, despite the sign code’s general requirement that no sign be erected without first obtaining a permit. Consequently, on April 28, 2003, the City sent Solantic a notice of violations of various sections of the sign code, including § 27-579 (requiring a permit to erect a sign); § 27-581(4) (prohibiting signs with any “visible movement achieved by electrical, electronic or mechanical means, except for traditional barber poles”); § 27-581(5) (prohibiting signs “with the optical illusion of movement by means of a design that presents a pattern capable of giving the illusion of motion or changing of copy”); and § 27-581(6) (prohibiting signs “with lights or illuminations that flash, move, rotate, scintillate, blink, flicker, or vary intensity or color except for time-temperature-date signs”). The notice also informed Solantic that violations of the sign code are punishable by fines of up to $250 a day, or $500 a day for repeat violations. The City’s Code Enforcement Board (“the Board”) conducted a hearing on June 11, 2003, and determined that Solantic’s sign violated the sign code. The Board subsequently directed Solantic, in an undated order, to cure the violation by taking four steps: (1) obtaining a sign permit; (2) modifying the sign to change copy no more than once a day; (3) modifying the sign so that its copy would not blink, flash, or scroll, but rather would permanently glow; and (4) controlling the sign only from the premises on which it was located. Following the Board’s June decision, Solantic applied for a sign permit. The district court concluded, however, that Solantic appeared to have continued to operate its sign without modifying it in accordance with the City’s order. Thus, on September 24, 2003, the City sent Solantic another notice of alleged violation of the same sections of the sign code. The Board held another hearing on October 8, 2003, after which it issued another undated order reiterating that Solantic was in violation of the sign code in three ways: by allowing the sign to change copy more than once a day; by allowing the sign to blink, flash, or scroll alternating messages; and by not controlling the sign solely from the property on which it was located. The Board thus ordered that Solantic be assessed fines totaling $75 per day ($25 for each of the three violations), running from September 3, 2003 (“the date of discovery or verification or violation(s)”) until all violations were cured. On October 28, 2003, Solantic filed an application for appeal from both the June and the October decisions of the Board. The City denied the appeal on November 3, 2003. Solantic then brought suit in the Circuit Court for the Fourth Judicial Circuit in Duval County, Florida, on January 5, 2004. Soon thereafter, the City removed the case to the United States District Court for the Middle District of Florida. In its second amended complaint (the operative pleading for purposes of this appeal), filed March 9, 2004, Solantic argued that the sign code violated the First Amendment in a variety of ways, including as a content-based regulation of speech and as an unlawful prior restraint. Solantic sought declaratory relief, in the form of a judgment declaring the City’s sign code to be unconstitutional and' unenforceable against Solantic, and absolving Solantic of any liability for accrued fines based on alleged violations of the sign code. In addition, Solantic sought preliminary and permanent injunctive relief enjoining enforcement of the sign code. On March 10, 2004, Solantic moved for a preliminary injunction. The district court held a provisional hearing on April 2, 2004, and ruled on May 3, 2004. The district court denied the preliminary injunction solely on the ground that Solantic had not shown a likelihood of success on the merits, without reaching the other relevant factors. The court reasoned that although the sign code’s permit requirement, was a prior restraint on speech, it was a content-neutral time, place, and manner restriction that did not. place excessive discretion in the hands of licensing officials, and was therefore constitutional. . It is from this order that Solantic took an interlocutory appeal, pursuant -to 28 U:S.C. § 1292(a)(1). II. A. The decision to grant or deny a preliminary injunction “is within the sound discretion of the district court and'will not be disturbed absent a clear abuse of discretion.” Palmer v. Braun, 287 F.3d 1325, 1329 (11th Cir.2002); see also, e.g., Horton, 272 F.3d at 1326; Siegel v. LePore, 234 F.3d 1163, 1178 (11th Cir.2000). We review the district court’s findings of fact for clear error, and its application of the law de novo, “premised on the understanding that ‘[application of an improper legal standard ... is never within a district court’s discretion.’ ” Johnson & Johnson, 299 F.3d at 1246 (quoting Am. Bd. of Psychiatry & Neurology, Inc. v. Johnson-Powell, 129 F.3d 1, 3 (1st Cir.1997)); see also Horton, 272 F.3d at 1326. Solantic argues that the district court abused its discretion in denying preliminary injunctive relief, since Neptune Beach’s sign code violates the First Amendment in three ways: first, the enumerated exemptions from its regulations render it an unconstitutional content-based restriction on speech; second, its permit requirement is an unlawful prior restraint; and third, it is unconstitutionally vague as applied to Solantic. Because we agree with Solantic as to the first two issues, we need not and do not reach the third. In determining whether the district court correctly concluded that Solantic was unlikely to succeed on the merits, we review the relevant provisions of the Neptune Beach sign code in some detail. The sign code regulates all signs erected within the City, other than those that are explicitly exempted from its regulations. See § 27-572 (“This article exempts certain signs from these regulations ....”); § 27-573 (“This article applies to all signs, and other advertising devices, that are constructed, erected, operated, used, maintained, enlarged, illuminated or substantially altered within the city.”); § 27-580 (enumerating exempt signs). At the outset, the sign code contains a number of findings of fact, pertaining to the safety and aesthetic harms that signs may cause. These findings state: (1) The manner of the erection, location and maintenance of signs affects the public health, safety, morals, and welfare of the people of this community. (2) The safety of motorists, cyclists, pedestrians, [and] other users of the public streets is affected by the number, size, location, lighting and movement of signs that divert the attention of drivers. (3) The size and location of signs may, if uncontrolled, constitute an obstacle to effective fire-fighting techniques. (4) The construction, erection and maintenance of large signs suspended . from or placed on the tops of buildings, walls or other structures may constitute a direct danger to pedestrian and vehicular traffic below, especially during periods of strong winds. (5) Uncontrolled and unlimited signs may degrade the aesthetic attractiveness of the natural and manmade attributes of the community and thereby undermine the economic value of tourism, visitation and permanent economic growth. § 27-574. In light of these findings of fact, the sign code lays out the “intentions and purposes of the city council” in enacting it: (1) To create a comprehensive and balanced system of sign control that accommodates both the need for a well-maintained, safe and attractive community, and the need for effective business identification, advertising and communication. (2) To permit signs that are: a. Compatible with their surroundings. b. Designed, constructed, installed and maintained in a manner which does not endanger public safety or unduly distract motorists. c. Appropriate to the type of activity to which they pertain. d. Large enough to convey sufficient information about particular property, the products or services available on the property, or the activities conducted on the property, and small enough to satisfy the needs for regulation. e. Reflective of the identity and creativity of individual occupants. (3)To promote the economic health of the community through increased tourism and property values. § 27-575. A “sign,” as broadly defined by the code, “means any device which is used to announce, direct attention to, identify, advertise or otherwise communicate information or make anything known. The term shall exclude architectural features or art not intended to communicate information.” § 27-576. Signs that are regulated by the sign code are subject to a variety of regulations, two of which are particularly important here. First, § 27-579 requires that a permit be obtained before a sign may be erected. Second, § 27-581 establishes numerous limitations on the form that signs may take, including that they may not contain any visible movement, § 27-581(4); they may not create the optical illusion of movement, including by changing copy, § 27-581(5); and they may not contain lights or illuminations that flash, move, rotate, scintillate, blink, flicker, or vary in intensity or color, except for time-temperature-date signs, § 27-581(6), among other things. However, the sign code expressly exempts from these regulations certain enumerated categories of signs. Two provisions in particular are significant here. First, § 27-580 provides: • The following types of signs are exempt from these regulations, provided they are not placed or constructed so as to create a hazard of any kind: (1) Signs that are not designed or located so as to be visible from any street or adjoining property. (2) Signs of two (2) square feet or less and that include no letters,. symbols, logos or designs in excess of two (2) inches in vertical or horizontal dimension, provided that such sign, or combination of such signs, does not constitute a sign prohibited by this Code. (3) Flags and insignia of any government, religious, charitable, fraternal, or other organization, provided that: a. No more than three (3) such flags or insignia are displayed on any one parcel of land; and b. The vertical measurement of any flag does not exceed twenty (20) percent of the total height of the flag pole, or in the absence of a flag pole, twenty (20) percent of the distance from the top of the flag or insignia to the ground. (4) Signs erected by, on behalf of; or pursuant to authorization of a governmental body, including, but not limited to the following: legal notices, identification signs, and informational, regulatory, or directional signs; (5) Integral decorative or architectural features of buildings, provided that such features do not contain letters, trademarks, moving parts or lights. (6) Signs on private premises .directing and guiding traffic and parking on private property, but bearing no advertising matter; (7) Signs painted or attached to trucks or other vehicles for identification purposes. (8) Official signs of a noncommercial nature erected by public utilities, provided that such signs do not exceed three (3) feet in height and the sign area does not exceed one-half ($) square foot in area. (9) Decorative flags or bunting for a celebration, convention, or commemoration of significance to the entire community when authorized by the city council for a prescribed period of time. (10) Holiday lights and decorations. (11) Merchandise, displays behind storefront windows so long as no part of the display moves or contains flashing lights. (12) Memorial signs or tablets, names of buildings and dates of erection when cut into any masonry surface or when constructed of bronze or other incombustible materials and attached to the surface of a building. (13) Signs incorporated into machinery or equipment by a manufacturer or distributor, which identify or advertise only the product or service dispensed by the machine or equipment, such as signs customarily affixed to vending machines, newspaper racks, telephone booths, and gasoline pumps. (14) Public warning signs to indicate the dangers of trespassing, swimming, animals, or similar hazards. (15) Works of art that do not constitute advertising. (16) Signs carried by a person; and (17) Religious displays (e.g. nativity scenes). § 27-580. Second, § 27-583(b) exempts only from the sign code’s permit requirement a variety of types of temporary signs. Exempt signs include: (1) On-site for sale/renVlease signs; (2) Grand opening signs; (3) Construction-site identification signs; (4) Signs to indicate the existence of a new business or business location; (5) On-site signs to announce or advertise such temporary uses as fairs, carnivals, circuses, revivals; sporting events, festivals or any public, charitable, educational or religious event; and (6) Election or political campaign related-signs. B. Solantic says that the sign code is a facially unconstitutional content-based restriction on speech, since it exempts from its regulations some categories of signs, based on their content, but not others. Because most (though not all) of the exemptions from the sign code are based on the content — rather than the time, place, or manner — of the message, we are constrained to agree with Solantic that the sign code discriminates against certain types of speech based on content. In evaluating the constitutionality of an ordinance restraining or regulating speech, “we first inquire whether the Ordinance is content-neutral.” Burk v. Augusta-Richmond County, 365 F.3d 1247, 1251 (11th Cir.2004); see also One World One Family Now v. City of Miami Beach, 175 F.3d 1282, 1286 (11th Cir.1999) (“It is only if we find the, governmental action content neutral that we examine whether the action is a permissible time, place, and manner regulation.”). If the ordinance is a content-neutral time, place, and manner restriction, it is subject to intermediate scrutiny — that is, it must not restrict speech substantially more than necessary to further a legitimate government interest, and it must leave open adequate alternative channels of communication. However, if the ordinance is content based, it is subject to strict scrutiny, meaning that it is constitutional only if it constitutes the least restrictive means of advancing a compelling government interest. Burk, 365 F.3d at 1251 (citations omitted). As the Supreme Court has explained: At the heart of the First Amendment lies the principle that each person should decide for himself or herself the ideas and beliefs deserving of expression, consideration, and adherence. Our political system and cultural life rest upon this ideal. Government action that stifles speech on account of its message, or that requires the utterance of a particular message favored by the Government, contravenes this essential right. Laws of this sort pose the inherent risk that the Government seeks not to advance a legitimate regulatory goal, but to suppress unpopular ideas or information or manipulate the public debate through coercion rather than persuasion. These restrictions “rais[e] the specter that the Government may effectively drive certain ideas or viewpoints from the marketplace.” For these reasons, the First Amendment, subject only to narrow and well-understood exceptions, does not countenance governmental control over the content of messages expressed by private individuals. Our precedents thus apply the most exacting scrutiny to regulations that suppress, disadvantage, or impose differential burdens upon speech because of its content .... In contrast, regulations that are unrelated to the content of speech are subject to an intermediate level of scrutiny, because in most cases they pose a less substantial risk of excising certain ideas or viewpoints from the public dialogue. Turner Broad. Sys., Inc. v. FCC, 512 U.S. 622, 641-42, 114 S.Ct. 2445, 129 L.Ed.2d 497 (1994) (citations omitted) (quoting Simon & Schuster, Inc. v. Members of State Crime Victims Bd., 502 U.S. 105, 116, 112 S.Ct. 501, 508, 116 L.Ed.2d 476 (1991)); see also Police Dep’t of the City of Chicago v. Mosley, 408 U.S. 92, 95, 92 S.Ct. 2286, 33 L.Ed.2d 212 (1972) (“[A]bove all else, the First Amendment means that government has no power to restrict expression because of its message, its ideas, its subject matter, or its content.”); R.A.V. v. City of St. Paul, 505 U.S. 377, 382, 112 S.Ct. 2538, 120 L.Ed.2d 305 (1992) (“Content-based regulations are presumptively invalid.”). The Supreme Court has articulated and applied various standards for determining whether a law is content based or content neutral. “As a general rule, laws that by their terms distinguish favored speech from disfavored speech on the basis of the ideas or views expressed are content based.” Turner, 512 U.S. at 643, 114 S.Ct. 2445. On the other hand, a content-neutral ordinance is one that “places no restrictions on ... either a particular viewpoint or any subject matter that may be discussed.” Hill v. Colorado, 530 U.S. 703, 723, 120 S.Ct. 2480, 147 L.Ed.2d 597 (2000); see also Burk, 365 F.3d at 1254 (A content-neutral ordinance “applies equally to all, and not just to those with a particular message or subject matter in mind.”). In determining whether the Neptune Beach sign code’s series of enumerated exemptions render it content based, we are guided by the Supreme Court’s plurality opinion in Metromedia, Inc. v. City of San Diego, 453 U.S. 490, 101 S.Ct. 2882, 69 L.Ed.2d 800 (1981), and by our own opinion in Dimmitt v. City of Clearwater, 985 F.2d 1565 (11th Cir.1993). In Metrome diet, the Court addressed the constitutionality of a San Diego ordinance that banned outdoor signs generally (to promote traffic safety and aesthetics), but exempted from the ban certain categories of signs. A majority of the Court agreed that the ordinance was constitutional insofar as it banned offsite commercial advertising while continuing to allow onsite commercial advertising, since the city could permissibly distinguish between types of commercial speech. Metromedia, 453 U.S. at 507-12, 101 S.Ct. 2882 (plurality opinion); id. at 541, 101 S.Ct. 2882 (Stevens, J., dissenting in part). However, both the four-Justice plurality opinion written by Justice White and the two-Justice concurrence written by Justice Brennan concluded that the ordinance’s regulation of noncommercial advertising was unconstitutional' — -although for wholly different reasons. The plurality found the ordinance unconstitutional in two ways. First, the ordinance continued to allow on-site commercial advertising, while banning on-site noncommercial advertising, which impermissibly favored commercial over noncommercial speech. Id. at 512-13, 101 S.Ct. 2882 (plurality opinion). Second— and most relevant to Solantic’s case — the plurality concluded that the ordinance’s series of exemptions from its general sign ban amounted to impermissible content-based discrimination among types of noncommercial speech. Id. at 514, 101 S.Ct. 2882. The ordinance exempted religious symbols, commemorative plaques of recognized historical societies and organizations, signs carrying news items or telling the time or temperature, signs erected in discharge of any governmental function, and temporary political campaign signs. By exempting these categories of signs, the plurality reasoned, the ordinance “distinguishes in several ways between permissible and impermissible signs at a particular location by reference to their content.” Id. at 516, 101 S.Ct. 2882. The plurality explained that “[w]ith respect to noncommercial speech, the city may not choose the appropriate subjects for public discourse: ‘To allow a government the choice of permissible subjects for public debate would be to allow that government control over the search for political truth.’ ” Id. at 515, 101 S.Ct. 2882 (quoting Consol. Edison Co. of N.Y. v. Pub. Serv. Comm’n of N.Y., 447 U.S. 530, 538, 100 S.Ct. 2326, 65 L.Ed.2d 319 (1980)). It thus found the ordinance invalid. Justice Brennan, writing for himself and Justice Blackmun, also concluded that the ordinance was unconstitutional, but not because of its exemptions. Instead, the concurrence analyzed the ordinance as a total ban on signs, explaining that, in contrast to the plurality “my view is that the practical effect of the San Diego ordinance is to eliminate the billboard as an effective medium of communication for the speaker who wants to express the sorts of messages [not exempted], and that the exceptions do not alter the overall character of the ban.” Id. at 525-26, 101 S.Ct. 2882 (Brennan, J., concurring in the judgment). Accordingly, the concurrence applied “the tests this Court has developed to analyze content-neutral prohibitions of particular media of communication” to conclude that the ban was invalid. Id. at 526-27, 101 S.Ct. 2882. Because the Metromedia plurality’s constitutional rationale did not garner the support of a majority, it has no.binding application to Solantic’s case. However, we subsequently adopted the same reasoning in Dimmitt v. City of Clearwater. In Dimmitt, a panel of this Court addressed an ordinance very similar' to Neptune Beach’s, striking it down as a facially unconstitutional content-based restriction on speech. The Clearwater ordinance required a permit to erect or alter a sign, but exempted- from this requirement certain types of signs, including: flags representing a governmental unit or body (limited to two per property), public signs posted by the government, temporary political signs, real estate signs, construction signs,' temporary window advertisements, occupant identification signs, street address signs, warning signs, directional signs, memorial signs, signs commemorating public service, stadium signs, certain signs displayed on vehicles, signs commemorating holidays, menus posted outside restaurants, yard sale signs, and signs customarily attached to fixtures such as newspaper machines and public telephones. The plaintiff — an automobile dealership seeking to display twenty-three American flags — brought facial and as-applied challenges to the ordinance. Focusing on the fact that the flag exemption applied only to flags of a governmental body, we found that the ordinance “cannot be treated as a content neutral regulation,” since “the display of the American flag or that of the State of Florida would be exempted from the permit process while a flag displaying the Greenpeace logo or a union affiliation would require a permit.” Dimmitt, 985 F.2d at 1569. After finding that the ordinance was content based, we considered whether it was nevertheless justified by a compelling state interest, concluding that the City’s asserted interest in aesthetics and traffic safety was “not a compelling state interest of the sort required to justify content' based regulation of noncommercial speech.” Id. at 1569-70. Finally, we concluded that even if aesthetics and traffic safety were compelling governmental interests, the ordinance was not narrowly tailored to achieve those ends, since “these asserted interests clearly are not served by the distinction between government and other types of flags.” Id. at 1570. We explained that “a municipality may not accomplish its purposes in promoting aesthetics and traffic safety by restricting speech depending upon the message expressed.” Id. Thus, we held “that by limiting the permit exemption to government flags, the City has unconstitutionally differentiated between speech based upon its content.” Id. There is little to distinguish the Neptune Beach sign code from the ordinances at issue in Dimmitt and Metromedia. Like the exemptions from the Clearwater and San Diego sign regulations, the exemptions contained in Neptune Beach’s sign code — both § 27-580’s exemptions from all regulations, and § 27-583(b)’s exemptions from the permit requirement — are largely • content based. Not all of the sign code’s exemptions are content based. For example, exemption (1) for signs not visible from any street or adjoining property, and exemption (16) for signs carried by a person, are restrictions on sign placement, not content. Cf. Members of the City Council of Los Angeles v. Taxpayers for Vincent, 466 U.S. 789, 811, 104 S.Ct. 2118, 80 L.Ed.2d 772 (1984) (upholding a Los Angeles ordinance prohibiting posting of signs on public property, reasoning that “[t]he private citizen’s interest in controlling the use of his own property’justifies the disparate treatment” of public and private property). Similarly, exemption (2) for signs smaller than two square feet and containing no letters or symbols larger than two inches pertains only to form, not to content. However, many of the sign code’s exemptions are plainly content based. For example, exemption (3) applies to flags and insignia only of a “government, religious, charitable, fraternal, or other organization.” Thus, a government or religious organization seeking to fly its flag may do so freely, whereas an individual seeking to fly a flag bearing an emblem of his or her own choosing would have to apply for a permit to do so, and would have to abide by all of the restrictions enumerated in § 27-581. For example, the government tax collector’s office could display a flag reading, “Stop Tax Evasion,”, whereas an individual homeowner could not display a flag saying, “Stop Domestic Violence,” since § 27-581(13) prohibits the use of the word “stop” in any nonexempt, nongovernmental sign. Exemption (4) is also content based, permitting governmental identification signs and informational signs to be freely posted, but requiring an individual or private organization who wishes to post a sign identifying his office or home, for example, to obtain a permit to do so. Moreover, pursuant to § 27-581, an exempt governmental sign could contain features such as moving parts or flashing lights, whereas the sign code’s general prohibitions on such features, see § 27-581(4), (6), bar the use of these devices by nonexempt individual and other private signs. Thus, the City government could display a ten-foot-tall sign identifying “City- Hall” in blinking lights, whereas § 27-581(6) would prohibit a homeowner from posting even a modestly sized sign using flashing lights to identify “The Smith Residence,” for example. Exemption (6) permits signs on private property to be posted freely if they are for the purpose of “guiding traffic and parking” on the property. Thus, without a permit, a homeowner could post a sign reading, “Parking in Back” and bearing a flashing neon arrow pointing toward the rear of the property, but not a traditional yard sign — which is recognized as “a venerable means of communication” that “may have no practical substitute,” Ladue, 512 U.S. at 54, 57, 114 S.Ct. 2038—with a political message like “Support Our Troops” or “Bring Our Troops Home.” Indeed, the only political signs exempt from any regulation are those “related to elections, political campaigns, or a-referendum,” and they are exempt only from the sign code’s permit requirement, are limited to four square feet in size in residential areas, and may not be displayed for more than fourteen days prior to and two days after an election. § 27 — 583(b)(6). Thus, while a “Re-Elect Mayor Smith” yard sign could be posted for a maximum of sixteen days, the illuminated parking sign may remain indefinitely. In other words, a large neon arrow receives more favorable treatment under the sign code than a political sign. Moreover, electioneering signs are the only form of political expression spared from the sign code’s permit requirement. To express any political message not directly related to an upcoming election, a would-be speaker must comply with the sign code’s permitting rules and all of its other restrictions. Thus, a sign espousing a viewpoint on a salient political issue — for example, “Reform Medicare,” “Save Social Security,” “Abolish the Death Penalty,” or “Overturn Roe v. Wade”— would be subject to a permitting process and to numerous, restrictions on form and placement from which other signs — such as those “guiding traffic and parking” — are exempt. Exemption (10) allows holiday lights and decorations to be displayed freely. Thus, a homeowner could plant a giant illuminated Santa Claus or a jack-o-lantern in his front yard, but not a figure of, say, the President or the Mayor. An illuminated reindeer would be permissible, whereas a less festive animal such as a dog would not. Moreover, an array of multicolored, flashing holiday lights could cover a homeowner’s roof year-round, whereas a simple political-campaign sign must, under § 27-583(6), be posted no more than two weeks before the election and removed within two days after. Exemption (12) provides that certain “memorial” signs on buildings may be freely erected. A comparable sign identifying living occupants, however — such as a plaque reading, “The Brown Family”— could be displayed only after obtaining a permit. Exemption (13) permits signs incorporated into machinery that advertise the service provided by the machine, but not comparable signs advertising the manufacturer or operator’s favored causes, for example. Thus, a sign reading, “Mow Your Lawn With A John Deere,” may receive more protection than oné that says, “Support Your Local Public Schools” or “Support Your Local Police.” Exemption (17) covers “[rjeligious displays (e.g. nativity scenes).” Thus, a homeowner could display year-round, without a permit, a manger scene stretching across his entire front yard and bearing a sign reading, “Worship Our Savior.” The scene could even include all of the features off-limits to nonexempt signs, such as moving parts, flashing lights, music, and even smoke. While that homeowner is free to employ limitless quantities of religiously themed figures, his neighbor could not freely display even a small, silent, stationary statue of the President, the Mayor, or any other secular figure, since such a display does not fall within any of the sign code’s enumerated exemptions. Nor could he put up, for example, an image of a soldier bearing the sign, “Support Our Troops” or “Bring Our Troops Home.” Indeed, even to erect either sign alone, without the soldier figure, would require a permit because of the nature of the message. Even those exemptions that favor certain speech based on the speaker, rather than the content of the message — such as exemption (8) for “[ojfficial signs of a noncommercial nature erected by public utilities,” and exemption (4) for signs “erected by, or on behalf of, or pursuant to the authorization of a governmental body”— are content based. Under these exemptions, public utilities and government bodies may freely erect signs expressing their political preferences, their positions on public policy matters, and, indeed, their chosen messages on virtually any subject. Thus, while a public utility could post a sign proclaiming, for example, “Choose Electric Power,” an individual homeowner or a private business could not display a sign reading, “Conserve Electricity: Use Solar Power.” Similarly, while the .city council could paper the entire City of Neptune Beach with signs advancing its agenda — for example, “Support School Vouchers,” or “Enlist in the National Guard”— an individual resident could not freely post even a single yard sign advocating the opposing position — for example, “Oppose School Vouchers,” or “Abolish the National Guard.” The Supreme Court has “frequently condemned such discrimination among different users of the same medium for expression,” which is another form of content-based speech regulation. Mosley, 408 U.S. at 96, 92 S.Ct. 2286; see also First Nat’l Bank of Boston v. Bellotti, 435 U.S. 765, 784-85, 98 S.Ct. 1407, 55 L.Ed.2d 707 (1978) (“In the realm of protected speech, the legislature is constitutionally disqualified from dictating the subjects about which persons may speak and the speakers who may address a public issue.” (emphasis added)). Cf. Ackerley Communications of Mass., Inc. v. City of Somerville, 878 F.2d 513, 518 (1st Cir.1989) (striking down a sign ordinance whose “grandfather” clause allowed certain speakers to use nonconforming signs, observing that “[e]ven if a complete ban on nonconforming signs would be permissible, we must consider carefully the government’s decision to pick and choose among the speakers permitted to use such signs”). The sign code exemptions that pick and choose the speakers entitled to preferential treatment are no less content based than those that select among subjects or messages. Moreover, even insofar as § 27-581 simply allows some types of messages to be displayed in a more prominent manner than others — for example, using flashing lights or moving parts — it constitutes content-based regulation of speech. See Café Erotica of Fla., Inc. v. St. John’s County, 360 F.3d 1274, 1289 (11th Cir.2004) (holding that limiting signs displaying political messages to a smaller size than signs displaying other types of messages constituted content discrimination); Whitton v. City of Gladstone, 54 F.3d 1400, 1410 (8th Cir.1995) (holding that prohibiting external illumination of political signs while allowing it for other signs was an unconstitutional content-based restriction, since “the message on the sign determines whether or not it may be externally illuminated”). In short, because some types of signs are extensively regulated while others are exempt from regulation based on the nature of the messages they seek to convey, the sign code is undeniably a content-based restriction on speech. Accordingly, our second inquiry is whether the sign code survives strict scrutiny. A content-based restriction on speech must be “necessary to serve a compelling state interest” and “narrowly drawn to achieve that end.” Perry Educational Ass’n v. Perry Local Educators Ass’n, 460 U.S. 37, 45, 103 S.Ct. 948, 74 L.Ed.2d 794 (1983). The Neptune Beach sign code fails both aspects of this requirement: the sign code is not narrowly tailored to accomplish the City’s asserted interests in aesthetics and traffic safety, nor has our case law recognized those interests as “compelling.” Even if we were to assume that Neptune Beach’s proffered interests in aesthetics or traffic safety were adequate justification for content-based sign regulations, the sign code cannot withstand strict scrutiny because it is not narrowly drawn to accomplish those ends. The problem is that the ordinance recites those interests only at the highest order of abstraction, without ever explaining how they are served by the sign code’s regulations generally, much less by its content-based exemptions from those regulations. In Dimmitt, we noted that even if the government’s interest in aesthetics and traffic safety could be sufficient justification for content-based regulation of signs, those interests “clearly áre not served by the distinction between government and other types of flags; therefore, the regulation is not ‘narrowly drawn’ to achieve its asserted end.” Dimmitt, 985 F.2d at 1570 (emphasis added) (quoting Perry, 460 U.S. at 45, 103 S.Ct. 948); see also, e.g., Gilleo, 986 F.2d at 1184 (holding that an ordinance was not narrowly drawn since it was not the “least restrictive alternative available”). The same is true here — the. sign code recites only the general purposes of aesthetics and traffic safety, offering no reason for applying its requirements to some types of signs but not others. As to traffic safety, the ordinance states that motorists’ safety “is affected by the number, size, location, lighting and movement of signs that divert the attention of drivers.” § 27-574(2). The sign code therefore permits signs that are “[djesigned, constructed, installed and maintained in a manner which does not endanger public safety or unduly distract motorists.” § 27-575(2). The code does not, however, explain how these factors affect motorists’ safety, or why a moving or illuminated sign of the permissible variety — for example, a sign depicting a religious figure in flashing lights, which would be permissible under § 27-580(17)’s exemption for “religious displays” — would be any less distracting or hazardous to motorists than a moving or illuminated sign of the impermissible variety — for example, one depicting the President in flashing lights, which falls within no exemption and is therefore categorically barred by § 27-581(5)’s prohibition on signs containing “lights or illuminations that flash.” Likewise, a homeowner could not erect a yard sign emitting an audio message saying, “Support Our Troops,” since § 27-581(9) generally bans signs that “emit any sound that is intended to attract attention,” but the government would be free to erect an equally distracting' — and presumably unsafe — sign emitting the audio message, “Support Your City Council,” since governmental signs are completely exempt from regulation under § 27-580(4). Regarding aesthetics, the sign code states that “[ujncontrolled and unlimited signs may degrade the aesthetic attraetiveness of the natural and manmade attributes of the community.” § 27-574(5). This provision similarly fails to explain how the sign code’s content-based differentiation among categories of signs furthers the City’s asserted aesthetic interests. For example, we are unpersuaded that a flag bearing an individual’s logo (which is not exempt from regulation), is any less aesthetically pleasing than, say, a flag bearing the logo of a fraternal organization (which is exempt from regulation under § 27-580(3)). Nor is it clear to us that a government-authorized sign reading, “Support Your City Council” in flashing lights (which is exempt from regulation under § 27-580(4)), or a religious sign reading, “Support Your Church” (which is exempt under § 27-580(17)), degrades the City’s aesthetic attractiveness any less than a yard sign reading, “Support Our Troops” in flashing lights. Although the sign code’s regulations may generally promote aesthetics and traffic safety, the City has simply failed to demonstrate how these interests are served by the distinction it has drawn in the treatment of exempt and nonexempt categories of signs. Simply put, the sign code’s exemptions are not narrowly tailored to accomplish either the City’s traffic safety or aesthetic goals. Moreover, even if the sign code’s regulations were narrowly tailored to promote aesthetics and traffic safety — and this codification does no such thing- — the plurality opinion in Metromedia and our decision in Dimmitt have said that these interests are not sufficiently “compelling” to sustain content-based restrictions on signs. In Metromedia, the plurality concluded that aesthetics and traffic safety constituted “substantial” but not “compelling” government interests, and thus were insufficient to justify the San Diego ordinance. Metromedia, 453 U.S. at 507-08, 101 S.Ct. 2882 (plurality opinion). Subsequently, in Dimmitt, we declared that “[t]he deleterious effect of graphic communication upon visual aesthetics and traffic safety ... is not a compelling state interest of the sort required to justify content based regulation of noncommercial speech.” Dimmitt, 985 F.2d at 1570. Thus, we found the city’s interests in aesthetics and traffic safety inadequate to justify exempting certain types of flags but not others from the city’s sign permit requirement. Id. at 1569-70. “As a practical matter,” we observed, “only the most extraordinary circumstances will justify regulation of protected expression based on its content.” Id. at 1570. Applying the Dimmitt analysis, we cannot reach a different conclusion in this case. The City has provided no justification, other than its general interests in aesthetics and traffic safety — which are offered only at the highest order of abstraction and applied inconsistently — for exempting certain types of signs but not others. We do not foreclose the possibility that traffic safety may in some circumstances constitute a compelling government interest, but Neptune Beach has not even begun to demonstrate that it rises to that level in this case. Accordingly, we are constrained to conclude that Neptune Beach’s sign code is not justified by a compelling government purpose. Because its enumerated exemptions create a content-based scheme of speech regulation that is not narrowly tailored to serve a compelling government purpose, Neptune Beach’s sign code necessarily fails to survive strict scrutiny. Moreover, these exemptions are not sever-able from the remainder of the ordinance; we are therefore required to find the sign code unconstitutional. C. Solantic also says that the sign code is unconstitutional for the wholly independent reason that its failure to impose time limits for permitting decisions makes it an invalid prior restraint on speech. We agree that the absence of any time limits renders the sign code’s permitting requirement unconstitutional. Whether a licensing ordinance— which constitutes a prior restraint on speech — must contain a time limit within which to make licensing decisions depends on whether the ordinance is content based or content neutral. As we have previously explained, see Granite State Outdoor Adver., Inc. v. City of St. Petersburg, 348 F.3d 1278, 1281 (11th Cir.2003), two Supreme Court cases establish the relevant framework. First, in Freedman v. Maryland, 380 U.S. 51, 85 S.Ct. 734, 13 L.Ed.2d 649 (1965), the Court invalidated a state law requiring motion pictures to be licensed prior to their release. The licensing board had discretion to deny licenses for films that were “obscene” or that “tend[ed], in the judgment of the Board, to debase or corrupt morals or incite to crimes.” Id. at 52 n. 2, 85 S.Ct. 734. In response to the danger of censorship posed by this ordinance, the Court held that the licensing process was valid only if it' contained certain procedural safeguards, which the plurality opinion in FW/PBS, Inc. v. City of Dallas, 493 U.S. 215, 110 S.Ct. 596, 107 L.Ed.2d 603 (1990), described in these terms: (1) any restraint prior to judicial review can be imposed only for a specified brief period .during which the status quo must be maintained; (2) expeditious judicial review of that decision must be available; and (3) the censor must bear the burden of going to court to suppress the speech and must bear the burden of proof once in court. Id. at 227, 110 S.Ct. 596. Although the Court was fragmented as to the precise extent of Freedman’s applicability in FW/ PBS, a majority of Justices reaffirmed the continuing validity of the first requirement — strict time limits for licensing decisions. See id. at 227-28, 110 S.Ct. 596 (plurality opinion); id. at 238, 110 S.Ct. 596 (Brennan, J., concurring in the judgment). Subsequently, in Thomas v. Chicago Park District, 534 U.S. 316, 122 S.Ct. 775, 151 L.Ed.2d 783 (2002), the Court upheld an ordinance requiring a permit before conducting any event involving more than fifty people. The Court distinguished Freedman, explaining: “Freedman is inapposite here because the licensing scheme at issue here is not subject-matter censorship but content-neutral time, place, and manner regulation of the use of a public forum.” Id. at 322, 122 S.Ct. 775. Because the Thomas ordinance was content neutral, the Court held that it was not subject to the Freedman requirements, explaining that “[w]e have never required that a content-neutral permit scheme regulating speech in a public forum adhere to the procedural requirements set forth in Freedman.” Id. However, the Court held that the ordinance was subject to the requirement that it contain “adequate standards to guide the licensing official’s discretion and render it subject to effective judicial review.” Id. at 323, 122 S.Ct. 775. Since Thomas, we have held that “time limits are not per se required when the licensing scheme at issue is content-neutral.” City of St. Petersburg, 348 F.3d at 1282 n. 6; see also Granite State Outdoor Adver., Inc. v. City of Clearwater, 351 F.3d 1112, 1118 (11th Cir.2003) (“[T]ime limits are required when their lack could result in censorship of certain viewpoints or ideas, but are not categorically required when the permitting scheme is content-neutral.” (emphasis and citation omitted)). We have explained that “whether Freedman or Thomas controls ... depends on whether the City’s sign ordinance is content-based or content-neutral.” City of St. Petersburg, 348 F.3d at 1281. Because Neptune Beach’s sign code is content based, its permitting scheme is subject to Freedman’s time-limit requirement. See Burk, 365 F.3d at 1255 n. 12 (“A content-based prior restraint must also satisfy the procedural requirements of Freedman v. Maryland.” (citation omitted)); see also Café Erotica, 360 F.3d at 1282-83 (applying Freedman’s, time-limit requirement to a sign permit requirement that was facially content neutral, but contained “the potential for content-based decisionmaking,” and finding the requirement satisfied since the ordinance required permit applications to be approved or denied within 14 days of submission). To satisfy the time-limit requirement, an ordinance 'must “ensure that permitting decisions are made within a specified time period.” Café Erotica, 360 F.3d at 1282. In Café Erotica, we found this requirement satisfied by a sign permit requirement explicitly providing that licensing decisions had to be made within 14 days. In contrast, “[a]n ordinance that permits public officials to effectively deny an application by sitting on it indefinitely is ... invalid,” since “[t]he opportunity for public officials-to delay is another form of discretion.” Lady J. Lingerie v. City of Jacksonville, 176 F.3d 1358, 1361-62 (11th Cir.1999). We have repeatedly applied this requirement in the context of licensing schemes for adult businesses, interpreting it as requiring that the ordinance contain a specific provision explicitly limiting the period of time within which licensing officials must make permitting decisions. Thus, for example, in Lady J. Lingerie v. City of Jacksonville, we struck down a requirement that adult businesses obtain a zoning exemption. Although the zoning board was required to conduct a hearing within 63 days of the business’s application, we held that “the ordinance’s failure to require a deadline for decision renders it unconstitutional.” Id. at 1363. In Redner v. Dean, 29 F.3d 1495 (1994), we struck down a licensing requirement for adult entertainment establishments, even though the ordinance placed a 45-day time limit on the administrator’s licensing decision, since the ordinance further provided that in the event the administrator exceeded the 45-day limit, “the applicant may be permitted to begin operating the establishment for which a license is sought, unless and until the County Administrator notifies the applicant of a denial of the application.” This provision, we held, rendered the time limit “illusory” and “risk[ed] the suppression of protected expression for an indefinite time period.” Id. at 1500-01. Again, in Artistic Entertainment, Inc. v. City of Warner Robins, 223 F.3d 1306 (11th Cir.2000), we struck down a licensing requirement for adult entertainment establishments even though it required the city council to approve or deny a license application within 45 days. We reasoned that, “although [the ordinance] imposes a deadline on the City to consider an adult business license application, it does not guarantee the adult business owner the right to begin expressive activities within a brief, fixed time frame,” since it did not provide for what would happen if the city council, “because of bad faith or innocent bureaucratic delays, fails to act on an application before the deadline.” Id. at 1310-11. Neptune Beach’s sign code contains no time limit of any sort for permitting decisions. Section 27-594, entitled “Permit application and approval procedures,” provides: “Within ten (10) days after receipt of an application, the building official shall determine that the information is complete or incomplete and inform the developer of the deficiencies, if any.” § 27-594(b). If the application is deemed incomplete, the applicant has ten days to correct the problem. If the application is complete, “the building official shall determine if the sign meets all provisions of this Code and shall issue the permit which states whether the application is approved, denied, or approved with conditions.” § 27-594(b)(2). However, no section of the sign code specifies any time period within which the building official must make this determination, thereby “risking] the suppression of protected expression for an indefinite time period.” Redner, 29 F.3d at 1500-01. The absence of any decisionmaking deadline effectively vests building officials with unbridled discretion to pick and choose which signs may be displayed by enabling them to pocket veto the permit applications for those bearing disfavored messages. The sign code’s permitting requirement is therefore precisely the type of prior restraint on speech that the First Amendment will not bear. III. Although this case is before us on appeal from the denial of a preliminary injunction, we do not think it necessary or prudent to confine our opinion to holding that Solantic has shown a likelihood of success on the merits, when it is altogether clear that Solantic will succeed on the merits of its First Amendment claims. We recognize that, ordinarily, “when an appeal is taken from the grant or denial of a preliminary injunction, the reviewing court will go no further into the merits than is necessary to decide the interlocutory appeal.” Callaway v. Block, 763 F.2d 1283, 1287 n. 6 (11th Cir.1985). However, under certain circumstances, a judgment on the merits is appropriate. In Thornburgh v. American College of Obstetricians & Gynecologists, 476 U.S. 747, 106 S.Ct. 2169, 90 L.Ed.2d 779 (1986), overruled on other grounds by Planned Parenthood v. Casey, 505 U.S. 833, 112 S.Ct. 2791, 120 L.Ed.2d 674 (1992), the Supreme Court held that the court of appeals had jurisdiction, on an appeal from the district court’s denial of a preliminary injunction, to strike down as unconstitutional portions of a Pennsylvania abortion statute, and affirmed the judgment of the court of appeals on the merits. See id. at 755-57, 106 S.Ct. 2169. The Court observed that appeals courts’ general approach of reviewing only the decision on whether to grant preliminary injunctive relief “is not inflexible,” id. at 756, 106 S.Ct. 2169, reasoning: “That a court of appeals ordinarily will limit its review in a case of this kind to abuse of discretion is a rule of orderly judicial administration, not a limit on judicial power.” Id. at 757, 106 S.Ct. 2169; accord Callaway, 763 F.2d at 1287 n. 6 (“[T]his rule is a rule of orderly judicial administration only. Section 1292(a)(1) of Title 28 of the United States Code, which governs appeals of interlocutory orders denying/granting injunctions, grants the courts jurisdiction to reach the merits, at least where there are no relevant facts at issue and the matters to be decided are closely related to the interlocutory order being appealed.”); 16 Charles Alan Wright, Arthur R. Miller & Edward H. Cooper, Federal Practice and Procedure § 3921.1, at 28 (2d ed. 1996) (“Jurisdiction of the interlocutory appeal is in large measure jurisdiction to deal with all aspects of the case that have been sufficiently illuminated to enable decision by the court of appeals without further trial court development.”). We have, on a number of occasions, reached the merits of cases before us on interlocutory appeal from the grant or denial of a preliminary injunction. In Calla-way v. Block, for example, we affirmed the district court’s denial of a preliminary injunction and disposed of the plaintiffs’ statutory construction and due process claims on the merits, “since both sides’ arguments go to the merits, no facts are at issue, and the questions raised are purely legal ones.” Callaway, 763 F.2d at 1287. We observed: “Reaching the merits in cases such as these obviously serves judicial economy, as long as the facts are not disputed and the parties have presented their arguments to the court.” Id. at 1287 n. 6. More recently, in Burk v. Augusta-Richmond County, 365 F.3d 1247 (11th Cir.2004), a panel of this Court proceeded to the merits of a case before us on interlocutory appeal from the district court’s denial of a preliminary injunction, and struck down on First Amendment grounds the county’s permitting requirement for public demonstrations. Reaching the merits was appropriate, we found, since the appeal presented pure questions of law, and since “our disposition dictates the outcome .of the underlying claim.” Id. at 1250; see also, e.g., Clements Wire & Mfg. Co. v. NLRB, 589 F.2d 894, 897-98 (5th Cir.1979) (finding it “apparent that appel-lee will not succeed on the merits of its action” and thus vacating the preliminary injunction and remanding “with instructions to the district court to enter a judgment consistent with this opinion”); Siegel, 234 F.3d at 1171 n. 4 (observing that the court has the authority to reach the merits on appeal from denial of preliminary injunction, but declining to do so, since the factual record was “largely incomplete and vigorously disputed”); Mercury Motor Express, Inc. v. Brinke, 475 F.2d 1086, 1091 (5th Cir.1973) (reviewing the district court’s issuance of a stay order that was not independently appealable, reasoning: “Because this case is properly before the court as an appeal from the denial of an injunction under 28 U.S.C.A. § 1292(a)(1) ... our permissible scope of review extends to the stay order as well. A court of appeals normally will not consider the merits of a case before it on an interlocutory appeal except to the extent necessary to decide narrowly the matter which supplies appellate jurisdiction, but this rule is one of orderly judicial administration and not a limit on jurisdictional power. ‘[Ojnce a case is lawfully before a court of appeals, it does not lack power to do what plainly ought to be done.’ ” (quoting 9 Moore’s Federal Practice ¶ 110.25[1] (2d ed.1972))). As the Supreme Court has explained, appellate review on the merits is properly conducted “if a district court’s ruling rests solely on a premise as to the applicable rule of law, and the facts are established or of no controlling relevance.” Thornburgh, 476 U.S. at 757, 106 S.Ct. 2169. “A different situation is presented, of course, when there is no disagreement as to the law, but the probability of success on the merits depends on facts that are likely to emerge at trial.” Id. at 757 n. 8, 106 S.Ct. 2169. Because the case before us falls into the first category, reaching a decision on the merits is the wiser course. The facts of the case are simple and straightforward, and the record needs no expansion. The First Amendment questions — which are the only issues before us — are purely legal; indeed, Solantic’s constitutional challenge to the sign code is facial rather than as applied, so that our resolution of the legal questions is only minimally intertwined with the facts. Moreover, the parties have fully briefed the legal issues and cogently presented them to both the district court and this Court. In addition, resolving the legal questions finally will substantially further the interests of judicial economy. Determining, de novo, whether the district court correctly found Solantic unlikely to succeed on the merits requires us to address complex and purely legal First Amendment issues that the district court has already fully considered once. Accordingly, “there is no point in remanding the case” for the district court to go through the motions of deciding the merits of Solantic’s First Amendment claims yet again, when our opinion compels the result to be reached. Illinois Council, 957 F.2d at 310. We therefore hold that Solantic prevails on the merits of these First Amendment claims, since the exemptions from Neptune Beach’s sign code render it an unconstitutional content-based scheme of speech regulation, and since the sign code’s lack of any time limits for permitting decisions make it an unlawful prior restraint on speech. We underscore that we express no opinion on — and leave it to the district court to consider on remand — Solantic’s requests for permanent injunctive relief and for a declaration that it is not liable for accrued fines. REVERSED and REMANDED. . References to the “sign code” are to Section 27, Article XV of the City of Neptune Beach Code of Ordinances. . Solantic also argued that the sign code violated analogous provisions of the Florida Constitution and raised a - promissory estoppel claim, based on the City’s grant of an electrical permit for Solantic’s EVMC sign. These claims have been abandoned on appeal. . Preliminary injunctive relief may be granted if the moving party establishes: (1) a substantial likelihood of success on the merits of the underlying case; (2) that he will suffer irreparabie harm unless an injunction issues; (3) that the harm he will suffer without an injunction outweighs the harm the injunction would cause the opposing party; and (4) that an injunction would not disserve the public interest. See, e.g., Horton v. City of St. Augustine, 272 F.3d 1318, 1326 (11th Cir.2001); Johnson & Johnson Vision Care, Inc. v. 1-800 Contacts, Inc., 299 F.3d 1242, 1246-47 (11th Cir.2002). . The district court has substantial discretion in weighing the four relevant factors to determine whether preliminary injunctive relief is warranted. As we have explained previously: This limited [abuse of discretion] review is necessitated because the grant or denial of a preliminary injunction is almost always based on an abbreviated set of facts, requiring a delicate balancing of the probabilities of ultimate success at final hearing with the consequences of immediate irreparable injury which could possibly flow from the denial of preliminary relief. Weighing these considerations is the responsibility of the district court. Siegel, 234 F.3d at 1178 (quoting Revette
