Defendant, the City of San Antonio, appeals the district court’s issuance of a preliminary injunction restraining the enforcement of a city ordinance that prohibits the future display or placement of portable signs. We reverse.
I.
Plaintiffs, who are in the business of supplying, leasing, renting and selling portable signs 1 in San Antonio, Texas, brought suit to challenge the constitutionality of San Antonio City Ordinance 62652 (“the ordinance”), enacted on April 3, 1986. The ordinance amends article V of Chapter 28 of the City Code of San Antonio by adding the following section:
Sec. 28-161 Prohibition of portable signs
It shall be unlawful to intentionally place or display, or cause to be placed or displayed, any portable sign on any premises other than at a properly zoned storage area of one properly licensed under this chapter unless it has been registered in accordance with section 28-162.
San Antonio, Tx., City Code ch. 28, art. V, § 28-161 (Apr. 3, 1986). Section 28-162 awards nonconforming status to portable signs in place prior to September 22, 1985, if those signs are registered and main- *1105 tamed. 2 In the commentary accompanying the ordinance, the purposes underlying the ordinance are expressly set forth: “Prohibiting further placement of portable signs is desired because they are not consonant with aesthetic values of the community and because they present unique safety problems.” 3 Commentary to San Antonio, Tx., City Code ch. 28, art. Y, §§ 28-161 & 28-162 (Apr. 3, 1986).
In their complaint, plaintiffs alleged that the ordinance violates the first and fourteenth amendments of the Constitution, and is an impairment of contract rights in violation of article I, section 10, clause 1 of the Constitution. In conjunction with their original complaint, plaintiffs filed a motion for a preliminary injunction, requesting that the district court restrain the City from enforcing the ordinance pending a final determination of the merits of the action. Pursuant to 28 U.S.C. § 636(b)(1)(B), the motion was referred to a United States Magistrate for the purpose of having the magistrate conduct an evidentiary hearing. After the hearing, the magistrate submitted to the district court proposed findings of fact and conclusions of law and a recommendation for disposition of the motion. The magistrate found that plaintiffs had satisfied the prerequisites to the issuance of a preliminary injunction and recommended that the motion for preliminary injunction be granted. The City filed objections to certain findings and conclusions. On August 13, 1986, after conducting a de novo review of the record, the district court issued a preliminary injunction prohibiting the enforcement of the ordinance. This appeal followed.
II.
The district court issued a memorandum opinion in which it concluded that the plaintiffs were entitled to a preliminary injunction, having satisfied the four prerequisites for such relief: (1) substantial likelihood that the moving party will ultimately succeed on the merits; (2) irreparable harm if the injunction is not issued; (3) the threatened harm to the moving party will outweigh any potential injury the injunction may cause the non-movant; and (4) the injunction will not disserve the public interest.
Lindsay v. City of San Antonio,
No. SA-86-CA-636 (W.D.Tex. Aug. 13, 1986) (memorandum opinion) at 6 [hereinafter cited as “Memorandum Opinion”] (citing
Star Satellite, Inc. v. City of Biloxi, 779
F.2d 1074, 1079 (5th Cir.1986);
Canal Auth. v. Callaway,
The court focused its attention on the question of whether the plaintiffs were likely to prevail on the merits and found that success on the merits was likely. The court viewed the ordinance, which it found to “effectively imposef ] an absolute ban on portable signs,”
4
Memorandum Opinion at 7, as a “content neutral” ordinance, affecting commercial and non-commercial speech equally. The court then identified the proper standard for reviewing such a content-neutral regulation as that set forth in
Members of the City Council v. Taxpayers for Vincent,
*1106 “[A] government regulation is sufficiently justified if it is within the constitutional power of the Government; if it furthers an important or substantial governmental interest; if the governmental interest is unrelated to the suppression of free expression; and if the incidental restriction on alleged First Amendment freedoms is no greater than is essential to the furtherance of that interest.”
Id.
at 805,
The court found that the photographs introduced into evidence by the plaintiffs “indicate that the aesthetic appearance of the City will imperceptibly change, at best, if portable signs are eliminated since portable signs appear to represent a small fraction of the total number of sign advertisements.” Id. The court found that the City had not shown that the ordinance furthers its aesthetic interests. The court went on to say that, even if the City had made that showing, the City could, according to certain testimony, control aesthetics by passing a less restrictive ordinance limiting the number of signs per commercial establishment. Further, the court noted its belief that “if the City were truly concerned with the effect of portable signs, it would not have created the grandfather clause allowing some signs to remain in place.” Id. at 10.
With respect to the asserted interest in traffic safety, the court found that the testimony adduced at the evidentiary hearing substantiated the traffic concerns. However, the court also found that the evidence established that the City’s goals could be accomplished by means less severe than a total ban. Indeed, the court found that all of the City’s concerns could be addressed by an ordinance imposing a regulation less drastic than a total ban. According to the court, the record contains substantial evidence of more “narrowly tailored” means to achieve both traffic safety and aesthetics.
Therefore, based on the reasoning discussed above, the court concluded that the plaintiffs had shown a likelihood of success on the merits. 6 The court summarized:
*1107 While traffic safety and aesthetics are legitimate governmental concerns, the ordinance furthers the former but not the latter. The evidence clearly showed that a total ban is completely unnecessary and unwarranted. The City can avoid traffic and other public safety problems related to portable signs by regulations concerning placement, construction and maintenance. Aesthetic appearance of the signs can also be regulated. The City ordinance, as now written, violates freedom of speech.
Memorandum Opinion at 17. Therefore, the court issued a preliminary injunction prohibiting the enforcement of the ordinance.
On appeal, the City raises two points of error. The first point of error appears to be an attack on the district court’s finding that the City had not shown a substantial reason for prohibiting the future placement of portable signs (i.e., that the ordinance would have only an “imperceptible” effect).
7
In this regard, the City argues that this court’s decision in
Dunagin v. City of Oxford,
The City’s second point of error is a more general attack on the district court’s determination that the plaintiffs were likely to succeed on the merits because the ordinance violates the first amendment. The City argues that the City Council has stated its legitimate reasons for the content-neutral prohibition embodied in the ordinance and has demonstrated them to the district court. The City notes that the Supreme Court has recognized that a content-neutral regulation does not, on review, warrant the same strictness of scrutiny that a content-based restriction warrants. Therefore, according to the City, since the ordinance does not abridge first amendment rights, the preliminary injunction should be dissolved.
Implicit in the City’s contentions on appeal must be the argument that the district court’s issuance of a preliminary injunction constitutes an abuse of that court’s discretion. The grant or denial of a preliminary injunction is committed to the discretion of the district court and will be upheld absent an abuse of discretion.
See, e.g., Dallas Cowboys Cheerleaders, Inc. v. Scoreboard Posters, Inc.,
(1) a substantial likelihood that plaintiff will prevail on the merits, (2) a substantial threat that plaintiff will suffer irreparable injury if the injunction is not granted, (3) that the threatened injury to plaintiff outweighs the threatened harm the injunction may do to defendant, and (4) that granting the preliminary injunction will not disserve the public interest.
Id.; see also Vision Center v. Opticks, Inc.,
It is generally accepted that a district court’s findings of fact made in connection with the grant or denial of a preliminary injunction will not be set aside unless clearly erroneous.
Id.
Where the standard of appellate review is the narrow “clearly erroneous” standard, the role of the appellate court is obviously quite limited. In the instant case, however, our role
*1108
as the reviewing court is not so limited. As this court noted in
Dunagin,
in deciding whether restrictions on speech are justified, appellate courts do not rely heavily on findings of fact made by trial courts.
Dunagin,
the Supreme Court’s recent commercial speech and other relevant speech cases indicate that appellate courts have considerable leeway in deciding whether restrictions on speech are justified. In none of them did the Court rely heavily on fact findings of the trial court.
Id.
at 749 n. 8.

This statement is in line with the Supreme Court's notation in a libel case,
Bose Corp. v. Consumers Union of United States, Inc.,
The view expressed in
Dunagin
seems consistent also with the Supreme Court’s most recent statement regarding the scope of appellate review in first amendment cases. In
Rankin v. McPherson,
— U.S. --,
The district court in
McPherson
had ruled that the plaintiff’s remark was not protected speech. On appeal, this court reversed.
McPherson v. Rankin,
III.
It is well-established that, as the district court found, the state may legit
*1109
imately exercise its police powers to advance the substantial governmental goals of aesthetics and traffic safety,
see, e.g., Vincent,
We believe that the district court’s critical finding that the ordinance would not further the City’s aesthetic interest cannot stand. As an initial matter, we note our concern about the approach taken by the district court in making its determination that the ordinance does not “further” the governmental interest in aesthetics. The district court found that photographs introduced into evidence by the plaintiffs “indicate that the aesthetic appearance of the City will
imperceptibly
change, at best, if portable signs are eliminated since portable signs appear to represent a small fraction of the total number of sign advertisements.” Memorandum Opinion at 9 (emphasis added). Such a finding by a trial court raises several concerns. First, it is unclear what factors should, and do, inform a court’s decision as to whether an effect on a governmental interest is “imperceptible.” The limits on such a determination seem boundless. In a related vein, when a trial court makes such a finding, the potential for the court to substitute its own judgment about aesthetics for that of the body charged with making aesthetic determinations is great. Left open is the possibility that the trial court will decide that nothing short of full achievement — as opposed to “furtherance” — of a governmental purpose is sufficient to justify a particular restriction on speech. Indeed, in the instant case, notwithstanding protestations by the court to the contrary,
10
the court’s general description of the problem with the ordinance — “its failure to accomplish its aesthetic purpose” — suggests that the district court took such an approach to the question raised under
Vincent
of whether the regulation “furthers an important or substantial governmental interest.”
Vincent,
Such an approach seems to be at odds with the principle that the district court itself recognized — that the elimination of all visual blight is not the constitutional prerequisite to an ordinance regulating a type of signage. The case law makes clear that a city is not precluded from curing only some of its visual blight,
see, e.g., Vincent,
While we are troubled by the implications of the district court’s approach, we recognize that the Supreme Court’s opinion in Vincent suggests that district courts can, in fact, determine that, because of the large number of signs in a particular area, an ordinance banning a type of signage will have only an inconsequential effect, and thus, that the ordinance does not “further” the interest in aesthetics. In the course of upholding an ordinance that prohibited the posting of signs on public property, the Court noted:
*1110 [T]here is nó finding that in any area where appellees seek to place signs, there are already so many signs posted on adjacent private property that the elimination of appellees’ signs would have an inconsequential effect on the esthetic values with which the City is concerned. There is simply no predicate in the findings of the District Court for the conclusion that the prohibition against the posting of appellees’ signs fails to advance the City’s esthetic interest.
Vincent,
In the instant case, the district court undoubtedly focused in on the above-quoted language from
Vincent
since its finding that the ordinance would imperceptibly change the aesthetic appearance of the City closely tracks the words of
Vincent.
While we assume, on the basis of
Vincent,
that the district court can make such a finding and that a finding of “inconsequential effect” can support the conclusion that an ordinance does not further the aesthetic interest, we also believe that this court, on review, is not bound by that finding.
11
See McPherson,
We have carefully reviewed the record in this case. The record consists of more than 25 photographs submitted by the plaintiffs, approximately 15 photographs submitted by the City, copies of various San Antonio city ordinances regulating signage, and a transcript of the testimony adduced at the evidentiary hearing. Our review of the evidence would lead us to conclude, contrary to the result reached by the district court, that the record demonstrates that the ordinance does, in fact, further the City’s aesthetic interest. However, even assuming that our view of the record is not persuasive, the best that can be said of the record evidence is that it is inconclusive. The photographs submitted by the City are simply pictures of portable signs, seemingly introduced into evidence to depict what we take to be relatively obvious — that the portable signs are unsightly.
Cf. Harnish v. Manatee County,
When the evidence is weighed taking into account the need to accord deference to the judgment of the body charged with the responsibility of making determinations about aesthetics,
cf. Clark v. Community for Creative Non-Violence,
We turn now to the district court’s finding that there is substantial evidence that more narrowly tailored means exist to achieve both traffic safety and aesthetics. For purposes of this opinion, we can as
*1111
sume,
arguendo,
that the traffic safety interest could be furthered by means of a more narrowly tailored ordinance.
Cf Harnish,
For guidance in approaching this question, we look to the reasoning employed by the Supreme Court in
Vincent
in making its determination of whether the scope of the restriction on the posting of signs on public property was “substantially broader than necessary to protect the City’s interest in eliminating visual clutter.”
Vincent,
Finally, we recognize that “[wjhile the First Amendment does not guarantee the right to employ every conceivable method of communication at all times and in all places ... a restriction on expressive activity may be invalid if the remaining modes of communication are inadequate.”
Vincent,
Therefore, for the reasons outlined above, we believe that the district court abused its discretion in granting the plaintiffs’ motion for a preliminary injunction since we disagree with the court’s conclusion that plaintiffs have demonstrated a likelihood of success on the merits.
*1112 IV.
On the basis of the foregoing, the district court’s order issuing a preliminary injunction is REVERSED.
Notes
. A portable sign is defined in the City Code as: any sign designed or constructed to be easily moved from one location to another, including signs mounted upon or designed to be mounted on a trailer, wheeled carriage, or other nonmotorized mobile structure. A portable sign which has its wheels removed shall still be considered a portable sign.
*1105 San Antonio, Tx., City Code ch. 28, § 28-6.
. On September 22, 1985, a moratorium had gone into effect prohibiting future placement of portable signs until such time as a permanent sign ordinance was passed.
. The commentary continues, in part:
Lightweight design and easy mobility of portable signs together with frequent use of electrical components create a potential for extraordinary safety hazards. Portable signs are often placed in close proximity to public rights-of-way in order to optimally attract the attention of motorists. Such placement creates visual obstruction of oncoming pedestrian and vehicular traffic for motorists ingressing or egressing from a place of business. Portable signs also have a tendency to be blown about in strong winds. Portable signs with electrical connections and components, if improperly maintained, pose a serious public safety hazard. Therefore, use of portable signs must conform to regulations for on-premise signage as set out in Article IV, Division 1 of this chapter.
Commentary to San Antonio, Tx., City Code ch. 28, art. V, §§ 28-161 & 28-162 (Apr. 3, 1986).
. The court also found that alternative channels for communication exist. See Memorandum Opinion at 9. The significance of the availability of alternative channels for communication is discussed infra at Part III.
. The court noted that the Eleventh Circuit, in
Harnish v. Manatee County,
(1) The First Amendment protects commercial speech only if that speech concerns lawful activity and is not misleading. A restriction on otherwise protected commercial speech is valid only if it (2) seeks to implement a substantial government interest, (3) directly advances that interest, and (4) reaches no further than necessary to accomplish the given objective.
Metromedia,
. The court went on to note that the plaintiffs had also satisfied the three remaining prerequisites to the issuance of a preliminary injunction.
. The City phrases its first argument on appeal several different ways. At one point in its brief, the City argues that “[t]he Courts below erred in failing to rule upon whether or not portable signs are unattractive since evidence was presented on this issue for ruling.” Brief of Appellant at 5. However, in its "conclusion” to its first argument, the City states, "[t]he Court erred in not ruling that the City of San Antonio had shown a substantial reason for prohibiting the future placement of portable signs on aesthetic grounds.” Id. at 7.
. By way of example, we mentioned that, "[i]n
Metromedia,
despite assertions that ‘the record is inadequate to show any connection between billboards and traffic safety* the judgment of the Court agreed with the ‘common-sense’ belief of local lawmakers and other courts that billboards do pose substantial traffic safety hazards.”
Dunagin,
In
Dunagin,
we also commented that "the decision on whether a regulation of commercial speech directly advances the state’s interest, for example, is an exercise of constitutional adjudication wherein appellate courts play a special role."
. In our opinion, authored by Judge Higginbotham, in the context of discussing "[t]he precise fit of the clearly erroneous standard of review and our duty to make ‘an independent constitutional judgment on the facts of the case,’ ”
[W]hen what was said and its context are undisputed, the constitutional "status” of the speech is to be independently examined by an appellate court. When what was said, but not its context, is disputed, the choice belongs to the trier of fact; on appeal, the determination of what was said is subject to review by the clearly erroneous standard, and the constitutional "status” of the statement is given independent review. Yet, when a factual dispute centers not on what was said but on its context, the deference due a trial court’s findings becomes less certain: factual conclusions about the speaker's intent, audience effect, and other elements of context are not so easily disentangled from a decision as to whether a statement was “political" or directed at "public concerns.”
McPherson,
. The court noted that, "Plaintiffs introduced photographs indicating that portable signs are no more of a traffic hazard and no more aesthetically displeasing that [sic] are many pole and permanent signs. Even if this is true the City is not precluded from curing only some of its visual blight and traffic problems." Memorandum Opinion at 9.
. Under the reasoning employed in this court's decision in McPherson, see supra at note 8, we believe that this finding is one for which independent review is appropriate.
. The Court noted that, in
Metromedia,
a majority of the Court had concluded that a prohibition on billboards was narrowly tailored to the visual evil that the City of San Diego sought to correct.
Vincent,
. The Court did note that "[t]he District Court found that the signs prohibited by the ordinance do constitute visual clutter and blight."
Vincent,
. As the Court in
Vincent
noted, ”[a]lthough the Court has shown special solicitude for forms of expression that are much less expensive than feasible alternatives and hence may be important to a large segment of the citizenry ... this solicitude has practical boundaries."
Vincent,
. We note that the City has pointed out that “San Antonio has special exemptions to address political and other non-commercial speech within its sign ordinances.” Brief of Appellant at 11.
