OPINION OF THE COURT
This case requires us to delineate, in a quite literal sense, the boundaries of the First Amendment’s protection of speech. In response to concerns about aggressive protests and confrontations at health care facilities providing abortions, the City of Pittsburgh enacted Ordinance No. 49 in December 2005. Pittsburgh, Pa., Code tit. 6, §§ 623.01-623.07. The Ordinance established two different kinds of zones around hospitals, medical offices, and clinics. Within the “buffer zone,” which extends “fifteen feet (15’) from any entrance to the hospital and or [sic] health care facility,” “[n]o person or persons shall knowingly congregate, patrol, picket or demonstrate.” § 623.04. The “bubble zone” encompasses “the public way or sidewalk area within a radius of one hundred feet (100’) from any entrance door to a hospital and/or medical office/clinic.” § 623.03. Within this one-hundred-foot zone, “[n]o person shall knowingly approach another person within eight feet (8’) of such person, unless such other person consents, for the purpose of passing a leaftlet or handbill to, displaying a sign to, or engaging in oral protest, education or counseling with such other person.” Id.
Plaintiff Mary Kathryn Brown brought suit against the City 1 under 42 U.S.C. § 1983, contending the Ordinance violated the United States and Pennsylvania constitutions, as well as a Pennsylvania statute. She also moved for a preliminary injunction preventing the City from enforcing the Ordinance against her. The District Court denied the motion, finding the Ordinance facially valid and that Brown had failed to show that the City had applied— or would apply — it in an unlawful manner. Relying on its reasoning in the opinion denying the preliminary injunction, the District Court also dismissed several counts of Brown’s Complaint. Brown ap *267 peals from both orders. We will reverse in part, vacate in part, dismiss in part, and remand for further proceedings consistent with this opinion.
I.
As the Ordinance itself attests, the Pittsburgh City Council sought to balance two important competing interests, “ensuring] that patients have unimpeded access to medical services while ensuring that the First Amendment rights of demonstrators to communicate their message to their intended audience is not impaired.” Pittsburgh, Pa., Code tit. 6, § 623.01. Noting that, before the Ordinance, the Pittsburgh Police had “consistently” been required “to mediate the disputes between those seeking medical counseling and treatment and those who would counsel against their actions,” the Council intended the Ordinance to establish “clear guidelines for activity in the immediate vicinity of the entrances to Health Care Facilities,” in order to allow “a more efficient and wider deployment” of policing services and to “help also reduce the risk of violence and provide unobstructed access to Health Care Facilities.” Id. During hearings on the proposed Ordinance, the Council heard public comments complaining of physical violence and verbal harassment at medical facilities providing abortions and claiming the Ordinance was needed to prevent future harm. 2
Brown is a registered nurse who works in Pittsburgh, Pennsylvania. For more than fifteen years, she has spent countless hours engaged in “sidewalk counseling” 3 and leafletting outside three medical services facilities covered by the Ordinance, attempting to dissuade women from undergoing abortions, warning them of the procedure’s ostensible dangers, and encouraging them to consider alternatives. Brown testified that she believes a conversational, sympathetic approach is the most effective, so in delivering her message, she refrains from yelling or using amplification devices. Before the Ordinance’s enactment, Brown had stood alongside the facilities’ entrances, or walked alongside women approaching the facilities, while attempting to distribute leaflets and engage in conversation.
Since the Ordinance took effect, Brown claims she has been effectively prevented from communicating her message. The buffer zone prevents her from distributing leaflets next to the facilities’ entrances, or from engaging in any advocacy within fifteen feet of those entrances. She claims that because of the bubble zone, she must either yell at people from a distance of eight feet — often while walking backward or being forced off the sidewalk into the street — or stand still and speak to them in the one or two seconds it takes them to *268 walk by. 4 According to Brown, women have not taken a single leaflet from her since the bubble zone foreclosed her ability to approach or walk alongside them.
Brown has never been arrested for violating the Ordinance. On two occasions police officers warned her to abide by its terms. The details of the first encounter are disputed by the parties, but Brown claims the police officer manifested an intent to enforce the Ordinance selectively, applying its restrictions to her anti-abortion expression but not her anti-pornography advocacy. Brown cannot identify the officer involved in the second incident but asserts he enforced the Ordinance against her while ignoring a clinic worker who had allegedly engaged in prohibited conduct. Brown also recounts other incidents in which clinic escorts, who assist women entering the facilities, have allegedly violated the Ordinance by engaging in forbidden activities within the fifteen-foot buffer zone and approaching well within eight feet of Brown in the bubble zone, without obtaining her consent, to denounce her pro-life message. Brown asserts that in none of these cases did the police enforce the Ordinance against the escorts.
In her Complaint, Brown claims the Ordinance violates rights guaranteed her by the U.S. and Pennsylvania Constitutions— specifically, the right to free speech and freedom of the press (pertinent to the distribution of pamphlets), U.S. Const, amend. I; Pa. Const, art. I, § 7, the right to due process, U.S. Const, amend. XIV; Pa. Const, art. I, § 26, the right to equal protection, U.S. Const, amend. XIV; Pa. Const, art. I, § 26, and the right to religious freedom, U.S. Const, amend. I; Pa. Const, art. I, § 3 — as well as by Pennsylvania’s Religious Freedom Protection Act, 71 Pa. Stat. Ann. §§ 2401-2407. Although the Complaint attacks the Ordinance facially and as applied, Brown’s preliminary injunction motion was grounded only on the as-applied challenge. Nevertheless, in the course of denying her motion, the District Court ruled the Ordinance facially valid. At oral argument on appeal, Brown’s counsel explained that because both parties had had an opportunity to brief the facial challenge fully on appeal, Brown was content for us to decide that issue. 5

We generally review a district court’s denial of a preliminary injunction for abuse of discretion but review the underlying factual findings for clear error and examine legal conclusions de novo.

McNeil Nutritionals, LLC v. Heartland Sweeteners, LLC,
We first consider Brown’s facial challenge.
As a general matter this court “will not invalidate a statute on its face simply because it may be applied unconstitutionally, but only if it cannot be applied consistently with the Constitution.” ... Thus, plaintiff[’s] facial challenge will succeed only if [the statute in question] “is unconstitutional in every conceivable application, or ... it seeks to prohibit such a broad range of protected conduct that it is constitutionally ‘overbroad.’ ”
Hohe v. Casey,
1.
This case implicates fundamental First Amendment interests. “[T]he public sidewalks, streets, and ways affected” by the Ordinance “are ‘quintessential’ public forums for free speech.”
Hill v. Colorado,
Reconciling these competing values, even on the level of abstract principle, is no easy task. Having to operationalize First Amendment doctrine in terms of metes and bounds, as we are compelled to do here, only increases the difficulty. If a restrictive zone of some kind is constitutionally permissible, how large may that zone be, and what kind of restrictions may it impose? As we confront these perplexing issues, we are mindful that we do not write on a blank slate. Several Supreme Court decisions, which examined zones very similar to the ones at issue here, control our analysis to a great extent.
Hill,
The One-Hundred-Foot Bubble Zone
As the District Court recognized, the bubble zone defined by the Ordinance is virtually identical to the one in the Colorado statute
Hill
found facially valid.
8
Brown v. City of Pittsburgh,
The petitioners in
Hill
put forward several different arguments contesting the statute’s constitutionality, but the Supreme Court found none of them convincing. The Court rejected the contention that the bubble zone’s restrictions are content-based, observing that “ ‘[t]he principal inquiry in determining content neutrality ... is whether the government has adopted a regulation of speech because of disagreement with the message it conveys.’ ”
Hill,
[T]he statute’s restriction seeks to protect those who enter a health care facility from the harassment, the nuisance, the persistent importuning, the following, the dogging, and the implied threat of physical touching that can accompany an unwelcome approach within eight feet of a patient by a person wishing to argue vociferously face-to-face and perhaps thrust an undesired handbill upon her. The statutory phrases, “oral protest, education, or counseling,” distinguish speech activities likely to have those consequences from speech activities ... that are most unlikely to have those consequences.
Id.
at 724,
The
Hill
Court also noted that the Colorado bubble zone is “not a regulation of speech” per se, but rather “a regulation of the places where some speech may occur.”
Id.
at 719,
Having concluded that the statute is content-neutral, the Court found that its restrictions on speech are sufficiently tailored to its legitimate objectives and leave open ample alternative avenues of communication.
Hill,
The Court was unmoved by petitioners’ argument that the state could achieve its objectives through less restrictive means. As noted above, a content-neutral time, place, and manner restriction embodied in a generally applicable regulation need not be “the least restrictive or least intrusive means of serving the statutory goal.”
Id.
at 726,
In sum, the Hill Court upheld the Colorado statute, finding it to be a content-neutral time, place, and manner regulation that was narrowly tailored to serve significant government interests while leaving open ample alternative avenues of speech. 10 As the bubble zone created by the Ordinance at issue here is a virtually verbatim copy of the Hill statute, we find this portion of the Ordinance, taken alone, to be facially valid under the First Amendment’s Free Speech Clause.
The Fifteen-Foot Buffer Zone
Although Brown concedes that the one-hundred-foot bubble zone is, taken on its own, constitutionally valid, she contends the fifteen-foot buffer zone cannot withstand constitutional scrutiny. In
Madsen
and
Schenck,
the Supreme Court upheld buffer zones (established by injunctions) requiring protesters to remain at least thirty-six feet and fifteen feet, respectively, from clinic entrances.
11
Brown asserts, however, that the Ordinance’s buffer zone is content-based, unlike the content-neutral zones in
Madsen
and
Schenck. Cf. Madsen,
The City does not deny that the buffer zone’s restrictions would be content-based if the Ordinance allowed the exempted categories of persons (including, most notably, volunteers assisting women in entering the building) to “picket or demonstrate” within the fifteen-foot zone while denying all others the same ability. But the City insists that the exemption should not be interpreted in such a manner, arguing that “[t]he Ordinance’s exemption for authorized clinic volunteers in the 15' fixed buffer zone is limited to circumstances where the volunteers are actually ‘engaged in assisting patients and other persons to enter or exit the hospital, medical office, or clinic.’ ” According to the City, the exemption allows the volunteers to enter the buffer zone only for this non-content-related purpose; notwithstanding the exemption, no person in the buffer zone may engage in “demonstrations or oral protest, education, or counseling with other individuals, including patients or other protesters.” Id. at 20.
When considering a facial challenge to a state law, “a federal court must, of course, consider any limiting construction that a state court or enforcement agency has proffered.”
Vill. of Hoffman Estates v. Flipside, Hoffman Estates, Inc.,
*275 We find § 623.04 amenable to the content-neutral construction urged by the City, that is, an interpretation prohibiting even the exempted classes of persons from “picketing] or demonstrat[ing]” within the buffer zone. Each of the exempted classes of persons — “police and public safety officers, fire and rescue personnel, ... other emergency workers[,] ... authorized security personnel employees [and] agents of the hospital, medical office or clinic engaged in assisting patients and other persons to enter or exit” — performs important safety functions. The clear purpose of the exemption is to ensure that the Ordinance’s restrictions do not impair the performance of those functions. Accordingly, public safety officers and emergency workers are exempt only “in the course of their official business,” and security personnel employees or agents of the health care facility are exempt only insofar as they are “engaged in assisting patients and other
persons to enter and exit” the facility. The functions performed by these persons are likely to require their presence in the buffer zone, thus warranting an exemption from § 623.04’s general prohibitions on congregating or patrolling within that space. But these functions do not require or entail the picketing or demonstrating activities generally proscribed by the buffer-zone restriction.
14
Consequently, a construction that does not include these advocacy activities in the exemption is “fairly possible.”
St. Cyr,
*276
As a content-neutral time, place, and manner regulation, the buffer zone is constitutionally valid if it is narrowly tailored to serve the government’s significant interests and leaves open ample alternative channels of communication.
See Hill,
The Combination of the Two Zones
The Ordinance creates not a single bubble or buffer zone in isolation, but a combination of the two types of zones.
Schenck
upheld a fixed buffer zone while invalidating the bubble-zone portion of an injunction.
Schenck,
If the Ordinance’s bubble and buffer zones, taken individually, are facially content-neutral, we see no reason why the Ordinance’s combination of the two zones would not also be content-neutral on its face. Accordingly, the test of constitutional validity is again found in
Ward:
a content-neutral time, place, and manner regulation of protected speech must be “narrowly tailored to serve a significant governmental interest, and [must] leave open ample alternative channels for communication of the information.”
Ward,
“The burden is on the City to demonstrate the constitutionality of its actions.”
Startzell v. City of Phila.,
Brown contends that the Ordinance’s restrictions are not sufficiently tailored to the interests they serve.
16
In particular, Brown notes that the Colorado statute upheld in
Hill
did not contain a buffer zone in addition to the one-hundred-foot bubble zone. Rather than take a prophylactic approach to blocked entrances, the statute directly proscribed the offending behavior, making it unlawful to knowingly “obstruct! ], detain! ], hinder! ], impede! ], or block[] another person’s entry to or exit from a health care facility.”
Hill,
Brown asserts that the addition of the buffer zone has an especially onerous effect on leafletting. In
Hill,
the Supreme Court expressed a similar concern. Although it found that the eight-foot separation imposed by the bubble zone would not necessarily present a significant obstacle to the display of signs and oral communication,
Hill,
The question is close, but we think Brown has the better argument. Although the Ordinance serves important government interests, we believe the layering of two types of prophylactic measures is “substantially broader than necessary to achieve [those] interest[s].”
Ward,
In determining whether the Ordinance’s restrictions are sufficiently tailored to the government’s interests, we find it significant that the Ordinance’s use of both types of zones appears to be unprecedented among regulatory schemes upheld by courts. We have noted that generally applicable time, place, and manner regulations enacted by legislatures are entitled to more deference than injunctions fashioned by courts.
See Madsen,
As demonstrated by the cases on which the City relies, either one of the two zones, standing alone, would advance the interests identified by the City. As
Hill
recognized, the one-hundred-foot bubble zone is designed especially to prevent harassment by enforcing a space of separation between protesters and unwilling listeners. But by
*281
preventing persons within the zone from approaching for advocacy purposes within eight feet of those who have not signaled their consent, the bubble zone also makes it more difficult for protesters to block entrances to the clinic.
Cf. Hill,
The fixed buffer zone also achieves the City’s interests. Not only does it work directly to prevent obstruction, but by preventing all but the expressly authorized individuals in § 623.04’s exemption from congregating anywhere within fifteen feet of a medical facility’s entrance, it also serves the City’s goal of preventing harassment and intimidation. At the very least, the buffer zone ensures that entering patients will not have to run a “gauntlet” of protesters,
Madsen,
For these reasons, the buffer zone, taken alone, promises to accomplish the City’s objectives of protecting patient access and preventing harassment. On the other hand, the addition of the bubble zone imposes significant burdens on protected speech. Leafletting, a “classic form[] of speech that lie[s] at the heart of the First Amendment,”
Schenck,
Although the holdings in
Madsen, Schenck,
and
Hill
do not dispose of the particular regulatory scheme presented here, the Court’s opinions in those cases support our conclusion. While upholding the thirty-six-foot buffer zone around clinic entrances,
Madsen
invalidated a provision of the injunction that would have prohibit
*282
ed defendants “from physically approaching any person seeking services of the clinic ‘unless such person indicates a desire to communicate’ in an area within 300 feet of the clinic.”
Madsen,
Similarly, in
Schenck
the Court upheld a fifteen-foot fixed buffer zone while striking down an additional bubble zone establishing a space of separation “around people entering and leaving the clinics.”
Schenck,
And in
Hill,
which applied the more relaxed tailoring standard pertinent to generally applicable regulations such as the Ordinance, the Court indicated that the bubble zone at issue in that case might raise serious constitutional concerns if applied to a clinic with an unusually wide entrance.
*283 2.
Because we have concluded that the combination of the bubble and buffer zones is invalid under the First Amendment, we consider the remaining claims in Brown’s legal challenge only insofar as they might invalidate either the bubble or buffer zone on its own. Brown asserts that the same flaw that allegedly renders the Ordinance a content-based restriction on speech — the exemption from the buffer zone restrictions of certain persons, such as health care facility employees and volunteers — also violates the Equal Protection Clause. Having already rejected the argument that each of the Ordinance’s zones is facially content-based, however, we also find that each is consonant with equal protection. “[WJhere the state shows a satisfactory rationale for a content-neutral time, place, and manner regulation, that regulation necessarily” survives scrutiny under the Equal Protection Clause.
McGuire I,
*284
Brown also challenges the Ordinance under the First Amendment’s Free Exercise Clause, claiming that its restrictions impermissibly interfere with her religiously motivated efforts to dissuade women from undergoing abortions.
23
See McTernan v. City of York,
The Pittsburgh Ordinance is a facially neutral law of general applicability. Its restrictions do not evince hostility to religion, nor do they selectively burden religious conduct. The Ordinance’s limitations apply irrespective of whether the beliefs underpinning the regulated expression are religious or secular. Brown disputes this conclusion, but her argument again relies on the mistaken premise that the Ordinance applies only to the speech of pro-life protesters and “not to clinic workers’ speech on the same topic.” On its face, the Ordinance is content-neutral and restricts the advocacy of all persons within the delimited zones. 25 Accordingly, the Ordinance is subject only to rational-basis review. As noted in our Ward analysis, the regulation serves the significant and legitimate state interests of preserving access and preventing harassment, intimidation, and violence. It thus satisfies the rational-basis test prescribed by Smith.
Brown contends the Ordinance is invalid under Pennsylvania’s Religious
*285
Freedom Protection Act (RFPA), 71 Pa. Stat. Ann. §§ 2401-2407. The RFPA was enacted in order to provide more protection to the exercise of religious beliefs than that currently afforded by the Free Exercise Clause of the First Amendment to the Federal Constitution.
See Combs,
Significantly, not all burdens on the exercise of religion trigger the RFPA’s heightened scrutiny. “In our modern regulatory state, virtually all legislation ... imposes an incidental burden at some level by placing indirect costs on an individual’s activity.... Pennsylvania ... [has] identified a substantiality threshold as the tipping point for requiring heightened justifications for governmental action.”
Combs,
*286 According to the RFPA, a law “substantially burdens” religious exercise if it: “(1) Significantly constrains or inhibits conduct or expression mandated by a person’s sincerely held religious beliefs;” “(2) Significantly curtails a person’s ability to express adherence to the person’s religious faith;” “(3) Denies a person a reasonable opportunity to engage in activities which are fundamental to the person’s religion;” or “(4) Compels conduct or expression which violates a specific tenet of a person’s religious faith.” 71 Pa. Stat. Ann. § 2403. Brown argues that the Ordinance “substantially burdens” her religiously motivated advocacy activities under each of the first three definitions. 28
In this case, the exercise of religion at issue — Brown’s advocacy activities in front of the clinics — is also expression protected by the First Amendment. Brown essentially urges us to interpret the RFPA as carving out an exemption to the Ordinance for religiously motivated ideas: its restrictions would not apply to religiously motivated expression that would be “substantially burdened” by the Ordinance. As we seek to determine what constitutes a substantial burden in this context, we confront two possibilities. First, “substantially burden” might be defined such that the protection the RFPA affords to religious speech is coextensive with (or lesser than) that afforded to speech generally by the First Amendment. Under this definition, if a given burden on expression is permissible under the First Amendment, it would also be permissible under the RFPA. Second, “substantially burden” might be defined such that the RFPA would provide more protection to speech motivated by religious belief than the First Amendment would provide to that same speech. Under this definition, for example, protesters inspired by non-religious beliefs could be restricted, consistent with the First Amendment, from approaching within eight feet of unwilling listeners in the bubble zone, but protesters motivated by religious beliefs might be exempt from that same restriction by virtue of the RFPA.
This second definition of “substantially burden” raises serious constitutional concerns because it would cause the applicability of the Ordinance to turn on whether a given advocacy activity was motivated by religious or non-religious beliefs. The exemption for religiously motivated expression would convert the Ordinance into precisely the kind of viewpoint-based restriction of speech that the Supreme Court has held presumptively invalid under the First Amendment.
See Rosenberger v. Rector & Visitors of Univ. of
Fix.,
In Pennsylvania law, as in federal law, it is a canon of statutory construction that “[w]hen the validity of an act of the (Legislature) is drawn in question, and if a serious doubt of constitutionality is raised, ... [courts] will first ascertain whether a construction of the statute is fairly possible by which the (constitutional) question máy be avoided.”
Com., by Creamer v. Monumental Props., Inc.,
This construction of the RFPA finds support not only in the canon of constitutional avoidance, but also in the history of the Supreme Court’s Free Exercise Clause jurisprudence. As noted, the purpose of the RFPA was to restore, under the auspices of state law, the free exercise jurisprudence that held sway under
Sherbert v. Verner,
Our cases are clear that governmental regulations which interfere with the exercise of specific religious beliefs or principles should be scrutinized with particular care. See, e.g., Sherbert v. Verner,374 U.S. 398 , 402-03,83 S.Ct. 1790 ,10 L.Ed.2d 965 (1963).... I read the Court as accepting these precedents, and ... holding that even if Sankirtan [a Krishna ritual involving the distribution of literature and solicitation of funds] is ‘conduct protected by the Free Exercise Clause,’ it is entitled to no greater protection than other forms of expression protected by the First Amendment that are burdened to the same extent by [the law at issue].
Id.
at 659 n. 3,
Accordingly, we find that the RFPA confers on religiously motivated expression the same extent of protection provided by the First Amendment to expression gener *288 ally. Since we have already determined that the bubble and buffer zones, taken individually and on their face, survive First Amendment scrutiny, we also find that their restrictions may be applied to Brown’s advocacy activities without “substantially burdening” her exercise of religion under the RFPA.
3.
Brown’s other claims, then, do not require us to modify our determination under the First Amendment: in tandem the buffer and bubble zones are inadequately tailored, but either of them individually would be facially valid. As this is an interlocutory appeal from the denial of a preliminary injunction, our review would normally be limited to deciding whether such an injunction should issue. But “the Supreme Court has held the ‘general rule’ of limited review is one of ‘orderly judicial administration, not a limit on judicial power.’ ”
OFC Comm Baseball v. Markell,
A decision on the merits is appropriate here, as the issue of the Ordinance’s facial validity has been fully briefed and argued, and the relevant facts — which, in the context of a facial challenge, do not encompass the features of particular clinic sites or specific incidents of enforcement — are undisputed. The dispositive question— whether, on these undisputed facts, the Ordinance is a content-neutral time, place, and manner regulation that is narrowly tailored to significant government interests and leaves open ample alternative channels of communication-is one of law. Because we find that the Ordinance’s combination of zones is not narrowly tailored, we hold on the merits that the Ordinance is facially invalid.
This conclusion, however, does not end the matter. The Ordinance has an express severability provision. Pittsburgh, Pa., Code tit. 6, § 623.06 (“If any portion of this Chapter is held invalid, unenforceable, or unconstitutional by any court of competent jurisdiction, it shall not affect the validity of the remaining portions of this Chapter, which shall be given full force and effect.”). The question, therefore, is which zone shall be invalidated and which shall be left in effect. Because either zone individually is lawful, the decision of which zone to employ belongs not to us but rather to the City. On remand, therefore, the City should inform the District Court of its *289 preference, and the court should enjoin enforcement of the other zone. 29
B.
Even to the extent that the Ordinance is facially valid, it may be unlawful as applied. Brown brings two types of as-applied challenges against the Ordinance. First, she argues that facts specific to the clinic sites at which she protests — the number of other businesses falling within the restrictive zones, the ambient noise levels, the width of the sidewalks, etc.— render the application of the Ordinance at those locations invalid under the Free Speech Clause of the First Amendment. Second, she contends that even if the Ordinance is content-neutral on its face, it has been selectively enforced by the Pittsburgh police, who have allegedly applied it only to persons, such as Brown, expressing pro-life views, and not to clinic workers and volunteers advocating pro-choice positions.
1.
In upholding the Colorado statute against a facial challenge, the
Hill
Court suggested that the result of as-applied challenges to the statute could depend on facts unique to the particular locations at which the statute’s restrictions were enforced.
See Hill,
Although the District Court acknowledged these arguments, it apparently found them unpersuasive. Brown com *290 plains that this aspect of the court’s decision was tainted by the court’s unannounced visit to, and inspection of, the Pittsburgh clinic sites, undertaken after the close of evidence and outside of the presence of the parties or the court reporter. 31 The City argues that it is “proper and appropriate for a Judge to take such a view pursuant to the Court’s inherent power to observe places or objects that are material to litigation but which cannot feasibly be brought or satisfactorily reproduced within the courtroom.” 2 McCormick on Evidence § 219 (6th ed.).
We believe the District Court’s site visits were improper. The problem is not that the court viewed locations outside of the courtroom. Rather, it is that the court did so outside the record and without notice to the parties.
See 2
McCormick on Evidence § 219 (“The judge in a bench trial may take a view [of a place or object outside the courtroom], though to do so without allowing the parties to attend invites a claim of error.”). “[B]eeause counsel were not informed when the judge would be conducting h[er] inspection, the parties had no way of knowing exactly what the court looked at, or how the judge went about h[er] visit.”
Clicks Billiards Inc. v. Sixshooters Inc.,
The City contends that any error in the site views was harmless.
32
We cannot agree. “Erroneous admission of evidence is harmless only if other competent evidence is ‘sufficiently strong’ to permit the conclusion that the improper evidence had no effect on the decision.”
Lillie,
Brown also complains that the District Court considered other evidence to which she did not have a chance to respond, such as newspaper articles reporting crime levels and transit cutbacks,
see Brown,
*292 2.
Brown’s second type of as-applied challenge argues that the Pittsburgh police have discriminated on the basis of viewpoint in enforcing the statute, applying its restrictions only to pro-life protesters like Brown and not to clinic workers and volunteers. As the City observes, because the Ordinance on its face does not discriminate based on content or viewpoint, Brown can prevail only if she establishes a pattern of discriminatory enforcement evincing an intent to target particular viewpoints. Under
Monell v. Department of Social Services,
Brown contends that “the Ordinance itself’ is the “policy” giving rise to municipal liability, and that “[w]hen ‘challenging the constitutionality of a policy ... ’ a plaintiff is not required to ‘allege a sequence of constitutional deprivations; the claim that the policy resulted in the plaintiff suffering such a deprivation satisfies
Monell.’ ” Doby v. DeCrescenzo,
Furthermore, in order to show such a pattern, Brown must prove not merely that the weight of Pittsburgh’s enforcement of the Ordinance has tended to fall more heavily on those who advocate one viewpoint (e.g., a pro-life view) than on those who advocate another (e.g., a pro-choice view); Brown must also prove that such enforcement occurred
because of
the viewpoint expressed. That is, Brown must show an intent to discriminate on the basis of viewpoint.
See McGuire II,
If a law is not unconstitutionally viewpoint- or content-based on its face simply because it is especially likely to affect advocates of a particular viewpoint, then the acts of police officers enforcing the law cannot be unconstitutionally viewpoint- or content-based simply because they primarily affect exponents of that view. On the as-applied level, too, differential impact alone is not sufficient evidence of unconstitutional viewpoint discrimination. “If we require invidious
legislative
intent to make this kind of otherwise content-neutral statute content or viewpoint discriminatory, then there seems no reason why we should not require invidious intent by the enforcers to take this statute outside of the category of content-neutrality now.”
McGuire II,
Our analysis yields the following conclusion: in order to establish municipal liability for selective enforcement of a facially viewpoint- and content-neutral regulation, a plaintiff whose evidence consists solely of the incidents of enforcement themselves must establish a pattern of enforcement activity evincing a governmental policy or custom of intentional discrimination on the basis of viewpoint or content. 38
Brown testified about two encounters she had with Pittsburgh police officers. On January 28, 2006, Officer Timothy Alexander arrived at the Planned Parenthood Clinic downtown and observed several protesters within the fifteen-foot buffer zone; the protesters dispersed upon his arrival. A security guard at the clinic pointed Brown out to Officer Alexander. When Officer Alexander approached Brown, she asked him to clarify the Ordinance’s terms. According to Brown’s testimony, the officer said she “could not stand and do anything within the fifteen foot spot in front of the clinic,” and that “he didn’t want to see [Brown] chasing women down the street.” Brown testified that there is a pornography shop located within the one-hundred-foot bubble zone in front of the Planned Parenthood Clinic. As Brown recalled matters, she showed Officer Alexander some anti-pornography literature she was carrying and asked him if she could distribute it in front of the pornography store. In Brown’s words, he replied that he “didn’t care what [Brown] did in front of the porn shop, as long as [she] wasn’t in front of the clinic.”
*295
Officer Alexander’s account of this encounter was somewhat different. He testified that he believed that the protesters at the clinic (he did not recall speaking specifically with Brown) showed him two different types of pamphlets and asked him if they could pass out either one, but that he did not pay attention to the content of the pamphlets. “I was not there ... to find out what the content of this information was,” he stated, “but only to let [the protesters] know that whatever they did they had to follow the [Ordinance’s] rules.” Officer Alexander further explained that “it is common practice in the [police] department that an officer would have to personally witness a violation before he would enforce an ordinance.”
Brown,
Brown’s second encounter with a police officer occurred in September 2006. Brown testified that, while standing outside of the fifteen-foot buffer zone in front of a clinic in the East Liberty neighborhood of Pittsburgh, she had tried to speak with a woman and hand her a piece of literature, at which point a clinic worker standing inside the buffer zone had hit Brown’s hand away and yelled at her to back up. Brown had walked over to a police car nearby and told an unidentified officer what had happened, but she testified that “he told me that he could not do anything about it because he had not seen the incident. I explained to him, he had ... to see the incident. He said it didn’t matter. He hadn’t seen it. He couldn’t do anything about it.” Brown recounted that the officer did, however, “tell me that if he saw me again going up behind women walking down the street, that he would arrest me.”
In her testimony, Brown recalled other incidents in which private citizens, usually clinic employees or volunteers, allegedly violated the Ordinance by confronting Brown, denouncing her views, and interfering with her attempts to communicate with consenting women — all within the Ordinance’s regulated zones. The District Court found, however, that “the police have not witnessed these events nor were they called to the scene.”
Brown,
We agree with the District Court that “[t]his evidence does not amount to a ‘pattern of unlawful favoritism’ ” in the City’s enforcement of the Ordinance.
Id.
at 486. First, “[t]o the extent that [Brown is] claiming that the statute is unconstitutional as applied merely because private pro-choice persons are engaging in acts that are illegal under the statute, [her] claim has nothing to do with the [Ordinance] at all and [she] cannot bring it because there is no state action.”
McGuire II,
Brown’s two encounters with police satisfy the state-action requirement, but they do not manifest discriminatory enforcement of the Ordinance, let alone discriminatory enforcement attributable to a municipal policy or custom. Officer Alexander explicitly testified that he did not care about the content of the literature distributed by protesters; regardless of subject matter or viewpoint, any advocacy activity within the prescribed zones had to conform to the Ordinance’s restrictions. Even if we relied solely on Brown’s account of this encounter, we would still find no evidence of content-based enforce *296 ment. 39 Brown stated that Officer Alexander said she could distribute literature in front of the pornography shop, which is within the one-hundred-foot bubble zone, but the Ordinance allows for the distribution of any kind of literature in that zone, as long as purveyors do not approach within eight feet of unwilling passersby. It is only within the fifteen-foot buffer zone immediately in front of clinic entrances that the distribution of literature is absolutely prohibited. Even on Brown’s own account, then, the evidence does not show that Officer Alexander made a distinction on the basis of the content of the message. It shows only that he distinguished, appropriately, between the locations at which the leaflet-ting occurred.
The September 2006 incident also fails to display an intent to discriminate on the basis of content or viewpoint. Although Brown claims that a clinic escort within the buffer zone violated the Ordinance by yelling at her to back up and hitting her hand away, 40 the unidentified officer to whom she reported this event repliéd that he did not see it. But even if he had seen the escort’s conduct, and even if we assume — in the absence of any record evidence — that the officer failed to enforce the Ordinance against the escort because of the escort’s viewpoint, Brown would still need to show that the officer’s inaction was the product of an unlawfully discriminatory governmental policy or custom. Here, the evidence before the District Court fell well short of that mark. As noted, one enforcement incident cannot meet the burden of proof imposed by Monell. And even if we assess the encounter with Officer Alexander in the light most favorable to Brown, we find no basis for inferring that the City has a policy or custom of enforcing the Ordinance based on the content of the speech or the viewpoint of the speaker. On the record before us, Brown has failed to substantiate her claim of unlawfully discriminatory enforcement. 41

To establish entitlement to a preliminary injunction,
the moving party must demonstrate that each of the following factors favors the requested relief: (1) the likelihood that the moving party will succeed on the merits; (2) the extent to which the moving party will suffer irreparable harm without injunctive relief; (3) the extent to which the nonmoving party will suffer irreparable harm if the injunction is issued; and (4) the public interest.
McNeil Nutritionals, LLC v. Heartland Sweeteners, LLC,
III.
In addition to appealing the District Court’s denial of preliminary injunctive relief, Brown also appeals from the court’s order dismissing several of her claims. Specifically, the court dismissed Brown’s freedom of the press and due process claims under the Federal Constitution, as well as her claims under the Pennsylvania Constitution, and her claim under the Pennsylvania Religious Freedom Protection Act. 42 The City did not seek dismissal of Brown’s claims under the Freedom of Speech Clause, Free Exercise Clause, or Equal Protection Clause of the Federal Constitution, and the District Court’s opinion therefore left these claims undisturbed. The District Court’s decision to partially dismiss Brown’s Complaint was based entirely on the analysis in its preliminary injunction opinion. Brown contends this was error because the standard for deciding a motion to dismiss under Federal Rule of Civil Procedure 12(b)(6) is different from the standard for deciding a motion for preliminary injunctive relief.
Ordinarily, we do not have appellate jurisdiction over an order dismissing only some of the claims in a case because 28 U.S.C. § 1291’s rule of finality requires that a district court judgment be “final as to all claims” in order to be appealable.
Mellon Bank, N.A. v. Metro Commc’ns, Inc.,
Here, it is not the case that review of the non-appealable partial dismissal order is necessary to ensure meaningful review of the appealable order denying a preliminary injunction. Rather, the converse is true — because the District Court rested its analysis of the motion to dismiss on its preliminary injunction opinion, meaningful review of the non-appealable order necessitates review of the appealable order. Accordingly, if pendent appellate jurisdiction exists, it must be because the two orders are “inextricably intertwined.”
Whether the two orders are “inextricably intertwined” is a difficult question, but we need not resolve it. Assuming arguendo that we can exercise pendent appellate jurisdiction over the partial dismissal order, we decline to do so here.
See Am. Soc’y for Testing & Materials v. Corrpro Cos.,
IV.
For the foregoing reasons, we will reverse the denial of preliminary injunctive relief with respect to Brown’s facial challenge. Reaching the merits, we hold that the combination of the Ordinance’s buffer and bubble zones is invalid but that either zone, individually, is valid on its face. We will affirm the District Court’s denial of preliminary injunctive relief with respect to Brown’s claim of selective enforcement, and vacate it with respect to her claim that the Ordinance is unconstitutional as applied to particular clinic locations. We will dismiss Brown’s appeal from the District *299 Court’s order partially dismissing her Complaint. And we will remand for appropriate further proceedings.
Notes
. For convenience, we use the term "the City” to refer collectively to Defendants the City of Pittsburgh, the Pittsburgh City Council, and Luke Ravenstahl, in his official capacity as Mayor of Pittsburgh.
. Brown contends the District Court erred in taking judicial notice of the minutes from the City Council's public meetings, noting that other witnesses "testified that no violent altercations occur at these facilities.” She does not, however, challenge the authenticity of the minutes themselves. We refer to the minutes here as part of the familiar process of consulting legislative history in order to illuminate legislative intent. We do not draw any conclusions about the truth of the testimony heard by the City Council, but note only that certain testimony asserting the need to protect public safety and preserve policing resources is consistent with the purposes stated in the text of the Ordinance itself.
. According to Brown's testimony, her "sidewalk counseling” consists of offering literature to women entering the medical facilities and telling them "[tjhat the [abortion] procedure itself is dangerous. That there is help available. That we're here to help [them]. That any reason [they] need[ ] to get an abortion, that we have help and solutions to all those problems that [cause them to] feel[ ] the need to do this.”
. Under the terms of the bubble zone, persons may not approach within eight feet of others in order to demonstrate or otherwise engage in advocacy. As long as persons within the bubble zone remain stationary, however, they are free to advocate, even if their intended audience approaches within eight feet of them.
. Our review of Brown’s motion for a preliminary injunction extends only to the arguments she presses on appeal, which do 'not include all claims raised in her Complaint.
. The District Court exercised jurisdiction under 28 U.S.C. §§ 1331 and 1367. We have jurisdiction to review the order denying a preliminary injunction under 28 U.S.C. § 1292(a)(1).
. Whether the City's stated goal of "a more efficient ... deployment” of policing resources should also be deemed a significant interest is a more difficult issue. Although the state has an undeniable interest in conserving finite resources, "[t]he government cannot restrict the speech of the public at large just in the name of efficiency.”
Waters
v.
Churchill,
. "Because the statute had not actually been enforced against” the
Hill
petitioners, "they only raised a facial challenge.”
Hill,
. The Colorado statute provides in pertinent part: "No person shall knowingly approach another person within eight feet of such person, unless such other person consents, for the purpose of passing a leaflet or handbill to, displaying a sign to, or engaging in oral protest, education, or counseling with such other person in the public way or sidewalk area within a radius of one hundred feet from any entrance door to a health care facility.” Colo.Rev.Stat. § 18-9-122(3).
. The petitioners in
Hill
also contended that the statute was unconstitutionally overbroad, arguing that "it protects too many people in too many places, rather than just the patients at the facilities where confrontational speech had occurred,” and that "it burdens all speakers, rather than just persons with a history of bad conduct.”
Hill,
More fundamentally, the petitioners’ argument reflected a basic misunderstanding of overbreadth doctrine. In the Court’s seminal overbreadth cases, "the government attempted to regulate nonprotected activity, yet because the statute was overbroad, protected speech was also implicated.”
Id.
(citing
Houston v. Hill,
. The buffer zone upheld in Madsen extended not only thirty-six feet from the clinic’s entrance, but also thirty-six feet from its driveway.
. A content-based regulation of speech is subject to strict scrutiny, a more exacting level of review than was applied to the regulations in
Madsen, Schenck,
or
Hill. See ACLU v. Mukasey,
. This principle of interpretation is consistent with Pennsylvania law.
See Commonwealth v. Monumental Props., Inc.,
. The effective performance of these functions may require other kinds of speech, as when police officers issue instructions to abide by the law and clinic employees or volunteers help direct patients in and out of the facilities. But this speech cannot be classified as picketing or demonstrating and does not fall within the scope of § 623.04’s general prohibitions.
. In
McGuire I,
the United States Court of Appeals for the First Circuit confronted an exemption similar to the one in § 623.04. The
McGuire
statute prohibited “knowingly approaching] another person or occupied motor vehicle within six feet of such person or vehicle,” without consent, “for the purpose of passing a leaflet or handbill to, displaying a sign to, or engaging in oral protest, education, or counseling with such other person in the public way or sidewalk area within a radius of 18 feet from any entrance door ... to a reproductive health care facility.”
McGuire I,
The Massachusetts legislature may or may not have intended the employee exemption to serve the purpose envisioned by the plaintiffs [and the district court]. There are other likely explanations. For example, the legislature may have exempted clinic workers — just as it exempted police officers — in order to make crystal clear what already was implicit in the Act: that those who work to secure peaceful access to [health care facilities] need not fear prosecution.
Id.
at 47. In the context of a facial challenge, the court explained, the question is whether the exemption "may rationally be said” to serve at least one permissible, viewpoint- and
*276
content-neutral purpose.
Id.; accord McGuire II,
. Brown incorrectly assumes that the Ordinance’s restrictions are content-based, and thus that they must satisfy a standard of strict scrutiny. Nonetheless, her arguments about the speech-restrictive effects of the Ordinance can also be measured against the tailoring requirement set forth as part of Ward’s intermediate-scrutiny standard.
. Brown makes two arguments that attempt to define what is necessary to achieve the government's interests in this case. First, she focuses narrowly on her own individual activ
*280
ity, asserting that because her advocacy in front of clinics has always been peaceful, the Ordinance "punishes [her] for phantom misconduct never committed by her.” But Brown's behavior is not the relevant benchmark for a generally applicable regulation like the Ordinance. “[T]he validity of the regulation depends on the relation its bears to the overall problem the government seeks to correct, not on the extent to which it furthers the government’s interests in an individual case.”
Ward,
Second, with respect to the "overall problem,” Brown asserts that the City has not established the existence at Pittsburgh health care facilities of harassment, dogging, or obstruction sufficient to justify the Ordinance’s restrictions. The Pittsburgh City Council’s public meeting minutes include comments complaining of precisely these problems. But Brown notes that other comments denied that such incidents ever occurred at the Pittsburgh clinics, and she complains that the public meeting minutes were inadmissible hearsay.
The public meeting minutes themselves are not crucial to our analysis, as we have held that "a factual basis” justifying legislation need not be "submitted to the legislative body prior to the enactment of the legislative measure.”
Phillips v. Borough of Keyport,
. In order to avoid running afoul of the bubble-zone restrictions, protesters might stand stationary in front of clinic entrances, but such conduct could be regulated — with less impact on expression than the buffer zone — by a law directly proscribing obstruction or blockading of entrances, such as the Colorado provision complementing the bubble-zone regulation upheld in Hill. See Colo. Rev.Stat. § 18-9-122(2) (prohibiting “knowingly obstructing], detaining], hindering], impeding], or blocking] another person’s entry to or exit from a health care facility”).
. Moreover, the relative simplicity of the buffer zone, the boundaries of which can be clearly and objectively marked on the pavement, would appear to present an easier enforcement task than that posed by the bubble zone's floating eight-foot space of separation.
Cf. McCullen v. Coakley,
. Although we have focused our analysis on the governmental interest in preventing harassment and obstruction of clinic entrances, we acknowledge that the City has also asserted an interest in conserving police resources. Even assuming that this interest is significant and justifies some sort of prophylactic regulation, however, the City has not demonstrated that an individual buffer or bubble zone would not adequately serve this goal. Accordingly, the City’s asserted interest in policing efficiency does not alter our conclusion that the combination of the two zones is insufficiently tailored.
. Brown also attacks the Ordinance as over-broad, but this argument appears to be limited to her as-applied challenge. See infra Section II.B.l. To the extent Brown brings a *283 facial overbreadth challenge, her attack is foreclosed by Hill. See supra note 10.
. The District Court determined that "[s]ince the case at hand involves the fundamental right to engage in free speech, strict scrutiny is warranted.”
Brown,
Supreme Court precedent supports this view. Where the Court has applied strict scrutiny to time, place, and manner regulations under the Equal Protection Clause, the restrictions were content-based.
See, e.g., Carey v. Brown,
. We do not question the sincerity of Brown’s religious convictions.
. Relying on dicta in
Smith,
some litigants pressing Free Exercise claims have presented a "hybrid rights” theory, contending that even a neutral, generally applicable regulation is subject to strict scrutiny if it "incidentally burdens rights protected by 'the Free Exercise Clause in conjunction with other constitutional protections, such as freedom of speech.' ”
Tenafly Eruv Ass’n v. Tenafly,
. The free exercise analysis here addresses only the facial validity of the Ordinance. Brown's claim that the city's police officers have selectively enforced it only against pro-life protesters, and not clinic workers, is examined in Section II.B.2 below.
. In 1993, Congress enacted the federal Religious Freedom Restoration Act (RFRA), 107 Stat. 1488, 42 U.S.C. §§ 2000bb to 2000bb-4 (amended 2000), which attempted to resurrect the compelling-interest test that had been applied to laws substantially burdening religious exercise before the Supreme Court’s
Smith
decision. But in
City of Boerne
v.
Flores,
. There is no question that the RFPA applies to the Ordinance at issue here. See 71 Pa. Cons.Stat. Ann. § 2406(a) ("This act shall apply to any State or local ordinance and the implementation of that law or ordinance, whether statutory or otherwise and whether adopted or effective prior to or after the effective date of this act.”).
. In
Commonwealth v. Parente,
. Of course, nothing we have said prohibits the City from enacting a different regulatory scheme consistent with the constitutional restrictions we have delineated in this opinion.
. Because the City may prefer the bubble to the buffer zone, see supra note 28, we consider Brown’s as-applied challenge to the former.
. The District Court explained, "The Plaintiff has provided the Court with exhibits in support of her motion for a preliminary injunction which display the facilities at issue and the surrounding zones. However, since those photographs were taken in 2006, the areas have changed. Therefore, the Court has taken a view of these areas pursuant to its inherent power to ‘observe places or objects that are material to litigation but which cannot feasibly be brought, or satisfactorily reproduced, within the courtroom.' "
Brown,
. Brown does not dispute that the improper visit is subject to a harmless error standard.
. Our remand will also allow the District Court to make explicit findings as to noise levels and other environmental conditions and to clarify the effect of these conditions on the merits of Brown's claim.
. In addition to the as-applied claims raised by Brown, Amicus National Legal Foundation argues that the Ordinance is unconstitutionally vague as applied because it is unclear what constitutes "consent” under the bubble-zone regulation.
See
Pittsburgh, Pa., Code tit. 6, § 623.03 ("No person shall knowingly approach another person within eight feet (8') of such person, unless such other person consents .... ”). Brown raised this argument before the District Court but omitted it on appeal. Although "we need not necessarily reach issues advanced only by amici,”
In re Paoli R.R. Yard PCB Litig.,
As Amicus acknowledges, the Supreme Court in
Hill
rejected a facial vagueness challenge to an identical statutory "consent” provision.
See Hill,
Although Amicus characterizes its vagueness claim as an as-applied challenge, it is essentially the same kind of facial attack rebuffed by
Hill.
Amicus does not cite any occasion on which the Ordinance was enforced against Brown on the ground that she had failed to obtain consent from a person she approached.
Cf. Coates v. City of Cincinnati,
Moreover, as in
Hill,
any vagueness concern "is ameliorated by the fact that” the Ordinance "contains a scienter requirement.”
Hill,
. Brown’s Complaint does not name as defendants any of the police officers allegedly involved in selective enforcement of the Ordinance.
. Justice Brennan did not join the plurality opinion in
Tuttle
because he found it "needlessly complicate[d].”
Tuttle,
. Demonstration of a "pattern” of selective enforcement may not be necessary in cases where there is direct evidence of an explicit policy to implement a facially neutral law in an unconstitutionally discriminatory way. But where a plaintiff relies primarily on incidents of discriminatory enforcement as circumstantial evidence of a municipal policy or custom, proof of a pattern is required, as Tuttle maltes clear.
. The District Court formulated the legal standard correctly: "In order to prevail, Brown must show that the Defendant City caused the alleged constitutional violation of which she complains through a municipal custom, practice, or policy. Additionally, in order to succeed on an as-applied First Amendment viewpoint discrimination claim, some showing of intent on the part of the government is necessary.”
Brown,
. Brown testified that she asked Officer Alexander “what [she] was able to do” within the restrictions of the Ordinance "because [she] didn’t want to get in any trouble.” According to Brown,
Multiple times [Officer Alexander] enforced the ordinance against me. He told me I could not stand and do anything within the fifteen foot spot in front of the clinic, that I must always obey a uniformed officer, including the security guard. That he didn’t want to see me chasing women down the street. That I could do anything I wanted to do in front of the pornography shop, because I showed him the literature I was passing out, both the abortion-related and the pornography-related. He told me he didn’t care what I did down in front of the porn shop, as long as I wasn't in front of the clinic.
. We assume, without deciding, that this conduct by the clinic escort violated the Ordinance.
But cf. McGuire II,
. Although we adjudicated the merits of Brown’s facial challenge, we do not do so with respect to her selective enforcement claim. Because a district court’s factfinding in a preliminary injunction proceeding does not preclude further factual development during subsequent proceedings on the merits, because Brown’s selective enforcement claim is more fact-intensive than her facial challenge, and because of the special solicitude courts show to First Amendment interests, we believe Brown is entitled to a further opportunity to develop the factual basis of her claim.
See St. Thomas-St. John Hotel & Tourism Ass’n, Inc.
v.
Gov’t of the U.S. Virgin Islands,
. The District Court denied the City’s motion to dismiss insofar as it sought the dismissal of Mayor Luke Ravenstahl and the Pittsburgh City Council as parties. This aspect of the District Court's order is not before us.
. Under Federal Rule of Civil Procedure 54(b), a district court "may direct entry of a final judgment as to one or more, but fewer than all, claims” and thus convert a partial dismissal into an appealable final order, but the District Court here did not do so.
