OPINION OF THE COURT SCIRICA, Chief Judge. 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 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 appeals 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. Brown is a registered nurse who works in Pittsburgh, Pennsylvania. For more than fifteen years, she has spent countless hours engaged in “sidewalk counseling” 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 walk by. 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. II. A. 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, 511 F.3d 350, 357 (3d Cir.2007). Where, as here, “First Amendment rights are at issue,” we have modified that standard. Child Evangelism Fellowship of N.J. v. Stafford Twp. Sch. Dist., 386 F.3d 514, 524 (3d Cir.2004). “Although we normally will not disturb the factual findings supporting the disposition of a preliminary injunction motion in the absence of clear error, we have a constitutional duty to conduct an independent examination of the record as a whole when a case presents a First Amendment claim.” Id. 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, 956 F.2d 399, 404 (3d Cir.1992) (quoting Robinson v. New Jersey, 806 F.2d 442, 446 (3d Cir.1986); Members of the City Council v. Taxpayers for Vincent, 466 U.S. 789, 796, 104 S.Ct. 2118, 80 L.Ed.2d 772 (1984)); accord McGuire v. Reilly (McGuire I), 260 F.3d 36, 47 (1st Cir.2001). This standard is consistent with the Supreme Court’s declaration in United States v. Salerno that a successful facial challenge requires the challenger to “establish that no set of circumstances exists under which the Act would be valid.” 481 U.S. 739, 745, 107 S.Ct. 2095, 95 L.Ed.2d 697 (1987). More recently, the Court has suggested that the bar may be slightly lower. Wash. State Grange v. Wash. State Republican Party, 552 U.S. 442, 128 S.Ct. 1184, 1190, 170 L.Ed.2d 151 (2008). Nonetheless, even under the Washington State Grange formulation, “a facial challenge must fail where the statute has a plainly legitimate sweep.” Id. (internal quotation marks omitted); see McCullen v. Coakley, 571 F.3d 167, 174 (1st Cir.2009) (“Howsoever worded, this standard imposes a very heavy burden on a party who mounts a facial challenge to a state statute.”). 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, 530 U.S. 703, 715, 120 S.Ct. 2480, 147 L.Ed.2d 597 (2000). The activities regulated by the Ordinance — “leafletting, sign displays, and oral communication” — are indisputably protected forms of expression, and “although there is debate about the magnitude of the statutory impediment to” Brown’s “ability to communicate effectively with persons in the regulated zones, that ability, particularly the ability to distribute leaflets, is unquestionably lessened by this statute.” Id. Nonetheless, “[i]t has been clear since [the Supreme] Court’s earliest decisions concerning the freedom of speech that the state may sometimes curtail speech when necessary to advance a significant and legitimate state interest.” Taxpayers for Vincent, 466 U.S. at 804, 104 S.Ct. 2118; see McGuire I, 260 F.3d at 42 (“Notwithstanding its exalted position in the pantheon of fundamental freedoms, free speech always must be balanced against the state’s responsibility to preserve and protect other important rights.”). The Ordinance here advances a number of significant government interests, including “protecting a woman’s freedom to seek lawful medical or counseling services in connection with her pregnancy” and “ensuring the public safety and order.” Madsen v. Women’s Health Ctr., Inc., 512 U.S. 753, 767-68, 114 S.Ct. 2516, 129 L.Ed.2d 593 (1994); see Hill, 530 U.S. at 715, 120 S.Ct. 2480 (“It is a traditional exercise of the States’ police powers to protect the health and safety of their citizens. That interest may justify a special focus on unimpeded access to health care facilities and the avoidance of potential trauma to patients associated with confrontational protests.” (internal quotation marks and citation omitted)). 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, 530 U.S. 703,120 S.Ct. 2480; Schenck v. Pro-Choice Network of W.N.Y, 519 U.S. 357, 117 S.Ct. 855, 137 L.Ed.2d 1 (1997); Madsen, 512 U.S. 753, 114 S.Ct. 2516. 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. Brown v. City of Pittsburgh, 543 F.Supp.2d 448, 471-72 (W.D.Pa.2008) (juxtaposing relevant provisions). Compare Pittsburgh, Pa., Code tit. 6, § 623.03, with Colo.Rev.Stat. § 18 — 9—122(3). At oral argument, Brown’s counsel conceded that, under Hill, § 623.03’s bubble zone, taken alone, is constitutional on its face. We agree that § 623.03’s bubble zone is materially indistinguishable from the one upheld in Hill. 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, 530 U.S. at 719, 120 S.Ct. 2480 (quoting Ward v. Rock Against Racism, 491 U.S. 781, 791, 109 S.Ct. 2746, 105 L.Ed.2d 661 (1989)); see id. at 737, 120 S.Ct. 2480 (Souter, J., concurring) (“[A] restriction is content based only if it is imposed because of the content of the speech, and not because of offensive behavior identified with its delivery.” (internal citation omitted)). The Colorado statute in Hill evinces no such invidious intent because its goals of protecting access to medical facilities and providing clear guidelines to police are “unrelated to the content of the demonstrators’ speech,” its “restrictions apply equally to all demonstrators, regardless of viewpoint, and the statutory language makes no reference to the content of the speech.” Id. at 719, 720, 120 S.Ct. 2480 (majority opinion) (internal quotation marks omitted). Nor is the statute content-based because it restricts knowingly approaching another for purposes of “oral protest, education, or counseling,” while imposing no limits on casual conversation — for example, saying “good morning.” This distinction serves not to suppress certain disapproved ideas, which would be presumptively invalid, but instead to further legitimate, content-neutral goals: [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, 120 S.Ct. 2480; see also McGuire I, 260 F.3d at 44 (“As long as a regulation serves a legitimate purpose unrelated to expressive content, it is deemed content-neutral even if it has an incidental effect on some speakers and not others.”). In short, “[t]he purpose of the Colorado statute is not to protect a potential listener from hearing a particular message. It is to protect those who seek medical treatment from the potential physical and emotional harm suffered when an unwelcome individual delivers a message (whatever its content) by physically approaching an individual at close range, i.e., within eight feet.” Hill, 530 U.S. at 718 n. 25, 120 S.Ct. 2480. 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, 120 S.Ct. 2480. That is, the bubble zone “does not entirely foreclose any means of communication.” Id. at 726, 120 S.Ct. 2480. It does not prohibit any message, whether expressed orally or by sign or leaflet, but simply imposes an eight-foot separation between the speaker and the audience (absent consent to approach closer). As such, the validity of the regulation is determined by reference to the Court’s time, place, and manner doctrine. Under that doctrine, “a regulation of the time, place, or manner of protected speech” is constitutionally permissible if it is “narrowly tailored to serve the government’s legitimate, content-neutral interests,” Ward, 491 U.S. at 798, 109 S.Ct. 2746, and “leave[s] open ample alternative channels for communication,” id. at 791, 109 S.Ct. 2746 (internal quotation marks omitted). When a time, place, and manner regulation takes the form of a generally applicable statute, it “may satisfy the tailoring requirement even though it is not the least restrictive or least intrusive means of serving the statutory goal.” Hill, 530 U.S. at 726, 120 S.Ct. 2480; see Madsen, 512 U.S. at 765, 114 S.Ct. 2516 (contrasting this standard with the more stringent scrutiny applicable to a challenged injunction, which is valid only if it “burden[s] no more speech than necessary to serve a significant government interest”). 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, 530 U.S. at 726, 120 S.Ct. 2480. The enforcement of an eight-foot barrier is a constitutionally tolerable burden on expression because “signs, pictures, and voice itself can cross an 8-foot gap with ease.” Id. at 729, 120 S.Ct. 2480. The Court acknowledged that “[t]he burden on the ability to distribute handbills is more serious because it seems possible that an 8-foot interval could hinder the ability of a leafletter to deliver handbills to some unwilling recipients.” Id. at 727, 120 S.Ct. 2480. But noting that the statute did not “prevent a leafletter from simply standing near the path of oncoming pedestrians and proffering his or her material, which the pedestrians can easily accept,” the Court found the regulation did not impose an excessive restraint. Id. In support of this conclusion, the Court referred to its earlier decision in Heffron v. International Society for Krishna Consciousness, Inc., 452 U.S. 640, 101 S.Ct. 2559, 69 L.Ed.2d 298 (1981), where it had upheld a regulation restricting the distribution of literature to fair booths. Heffron emphasized that the fair-booth restriction “primarily burdened the distributors’ ability to communicate with unwilling readers” and afforded an adequate opportunity “to win the[ ] attention” of willing listeners. Hill, 530 U.S. at 728, 120 S.Ct. 2480 (quoting Kovacs v. Cooper, 336 U.S. 77, 87, 69 S.Ct. 448, 93 L.Ed. 513 (1949)). The bubble zone established by the Colorado statute (and the Pittsburgh Ordinance) impairs primarily the effort to communicate with unwilling listeners, and by allowing leafletters significant mobility, it “interferes far less” with communication than the state-fair regulation upheld in Heffron. Id. at 730, 120 S.Ct. 2480. In sum, in light of the state’s “substantial and legitimate interest” in protecting those attempting to enter health care facilities, who “are often in particularly vulnerable physical and emotional conditions,” the Court found the Colorado bubble zone to be “an exceedingly modest restriction on the speakers’ ability to approach.” Id. at 729, 120 S.Ct. 2480. 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, 120 S.Ct. 2480. “[Wjhether or not the 8-foot interval is the best possible accommodation of the competing interests at stake,” the Court believed it was obliged to “accord a measure of deference to the judgment of the Colorado Legislature.” Id. at 727, 120 S.Ct. 2480. The Court rejected the view, advanced by Justice Kennedy in his dissent, id. at 777-78, 120 S.Ct. 2480 (Kennedy, J., dissenting), that the state interests at stake could be adequately served — with less restriction of protected speech — by enforcing pre-existing prohibitions on battery and harassment. The Court recognized that the statute’s “prophylactic approach” to “protecting] those who wish to enter health care facilities ... will sometimes inhibit a demonstrator whose approach in fact would have proved harmless.” Id. at 729, 120 S.Ct. 2480 (majority opinion). But it found the bubble-zone approach to be “justified by the great difficulty of protecting, say, a pregnant woman from physical harassment with legal rules that focus exclusively on the individual impact of each instance of behavior, demanding in each case an accurate characterization (as harassing or not harassing) of each individual movement within the 8-foot boundary.” Id. In light of the difficulties inherent in making the individualized, case-by-case judgments necessary to enforce a battery or harassment law, the Court concluded that “[a] bright-line prophylactic rule may be the best way to provide protection, and, at the same time, by offering clear guidance and avoiding subjectivity, to protect speech itself.” Id. 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. 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. Brown asserts, however, that the Ordinance’s buffer zone is content-based, unlike the content-neutral zones in Madsen and Schenck. Cf. Madsen, 512 U.S. at 762-64, 114 S.Ct. 2516. The Ordinance provides that “[n]o person or persons shall knowingly congregate, patrol, picket or demonstrate” within fifteen feet of an entrance to a hospital or health care facility. Pittsburgh, Pa., Code tit. 6, § 623.04. But it explicitly exempts certain persons from the buffer zone’s restrictions: “This section shall not apply to police and public safety officers, fire and rescue personnel, or other emergency workers in the course of their official business, or to authorized security personnel employees or agents of the hospital, medical office, or clinic engaged in assisting patients and other persons to enter or exit the hospital, medical office, or clinic.” Id. It is this exemption, Brown contends, that makes the Ordinance content-based on its face. 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., 455 U.S. 489, 494 n. 5, 102 S.Ct. 1186, 71 L.Ed.2d 362 (1982); see Ward, 491 U.S. at 795-96, 109 S.Ct. 2746. Here, the parties have identified no such limiting construction other than the one offered by the City in this litigation, and we have found none. Cf. McGuire v. Reilly (McGuire II), 386 F.3d 45, 52 (1st Cir.2004) (noting that the Massachusetts Attorney General had set forth a limiting interpretation of the statute at issue in a letter sent to police departments). In the absence of a limiting construction from a state authority, we must “presume any narrowing construction or practice to which the law is fairly susceptible.” City of Lakewood v. Plain Dealer Publ’g Co., 486 U.S. 750, 770 n. 11, 108 S.Ct. 2138, 100 L.Ed.2d 771 (1988) (internal quotation marks omitted); see also INS v. St. Cyr, 533 U.S. 289, 299-300, 121 S.Ct. 2271, 150 L.Ed.2d 347 (2001) (“[I]f an otherwise acceptable construction of a statute would raise serious constitutional problems, and where an alternative interpretation of the statute is ‘fairly possible,’ we are obligated to construe the statute to avoid such problems.” (quoting Crowell v. Benson, 285 U.S. 22, 62, 52 S.Ct. 285, 76 L.Ed. 598 (1932))); Davet v. City of Cleveland, 456 F.3d 549, 554 (6th Cir.2006) (“[FJederal courts construe state statutes to avoid constitutional difficulty when fairly possible .... ” (internal quotation marks omitted)). 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. Consequently, a construction that does not include these advocacy activities in the exemption is “fairly possible.” St. Cyr, 533 U.S. at 300, 121 S.Ct. 2271. Such a reading may, in fact, be the best way to give effect to the previously quoted phrases limiting the exemption to the performance of particular functions. Having determined that § 623.04 is susceptible to a construction that avoids serious constitutional concerns, we adopt that construction and hence find the buffer-zone provision facially content neutral. 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, 530 U.S. at 725-26, 120 S.Ct. 2480. The zone may be “narrowly tailored” even if it is not “the least restrictive or least intrusive means” of serving those interests. Id. at 726 n. 32, 120 S.Ct. 2480 (quoting Ward, 491 U.S. at 798, 109 S.Ct. 2746). In Mad-sen and Schenck, the Supreme Court upheld buffer zones extending thirty-six and fifteen feet, respectively, from clinic entrances. As noted, because those buffer zones were established by injunctions rather than generally applicable legislation, they were subject to a more demanding standard of review: the Court asked “whether the challenged provisions of the injunction burden no more speech than necessary to serve a significant government interest.” Madsen, 512 U.S. at 765, 114 S.Ct. 2516; see McCullen, 571 F.3d at 178-79 (distinguishing the tailoring test applicable to generally applicable regulations from the test applicable to injunctions). The government interests at stake here are significant and largely overlap with those recognized in Madsen and Schenck. Accordingly, since the Court upheld the buffer zones in Madsen and Schenck (one of which was more than twice as large as the buffer zone here), finding them sufficiently tailored under a test more exacting than the one applicable here, the buffer zone established by the Ordinance is a fortiori constitutionally valid. This conclusion is bolstered by the First Circuit’s recent decision in McCullen v. Coakley, which rejected a facial challenge to a Massachusetts statute establishing 35-foot buffer zones — more than twice the size of the Ordinance’s buffer zones here — around the entrances and driveways of reproductive health care facilities. See An Act Relative to Public Safety at Reproductive Health Care Facilities, Mass. Gen. Laws ch. 266, § 120E1/2. The court found that the statute was “content-neutral, narrowly tailored, and l[eft] open ample alternative channels of communication.” McCullen, 571 F.3d at 184. 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, 519 U.S. at 377-78, 117 S.Ct. 855. But as the Hill Court later explained, the constitutional defect in the Schenck bubble zone lay in its specific attributes; it imposed a fifteen-foot separation between speaker and listener and otherwise represented an excessive burden on speech. Hill, 530 U.S. at 726-27, 120 S.Ct. 2480. By contrast, Hill upheld a bubble zone that, like the one here, imposed a shorter, eight-foot separation, allowed the speaker to remain stationary even if passersby approached within eight feet, and protected speakers by incorporating a scienter requirement. Id.; see id. at 740, 120 S.Ct. 2480 (Souter, J., concurring) (“In Schenck, the floating bubble was larger (15 feet) and was associated with near-absolute prohibitions on speech.”). In other words, although Schenck informs our constitutional analysis (along with Madsen and Hill), its different facts mean we cannot simply adopt its conclusion, but must instead examine the specific features of the two zones combined here. 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, 491 U.S. at 791, 109 S.Ct. 2746. Because we have already determined that the Ordinance serves significant government interests, the key remaining considerations are the “narrowly tailored” and “alternative channels for communication” requirements. In Ward, the Supreme Court made clear that the “narrowly tailored” standard affords the government some discretion in deciding how best to achieve its legitimate purposes. See also Hill, 530 U.S. at 727, 120 S.Ct. 2480 (“[W]hether or not the 8-foot interval is the best possible accommodation of the competing interests at stake, we must accord a measure of deference to the judgment of the Colorado Legislature.”). As noted, a content-neutral time, place, and manner regulation may be sufficiently tailored even if it is not “the least restrictive or least intrusive means of serving the government interests at stake.” Ward, 491 U.S. at 798, 109 S.Ct. 2746; see Hill, 530 U.S. at 736, 120 S.Ct. 2480 (Souter, J., concurring) (“[0]ur cases quite clearly hold that restrictions on the time, place, or manner of protected speech are not invalid ‘simply because there is some imaginable alternative that might be less burdensome on speech.’ ” (quoting United States v. Albertini, 472 U.S. 675, 689, 105 S.Ct. 2897, 86 L.Ed.2d 536 (1985))). “[T]he requirement of narrow tailoring is satisfied ‘so long as the ... regulation promotes a substantial government interest that would be achieved less effectively absent the regulation.’ ” Ward, 491 U.S. at 799, 109 S.Ct. 2746 (quoting Albertini, 472 U.S. 675, 689, 105 S.Ct. 2897 (1985)); see id. at 800, 109 S.Ct. 2746 (explaining that courts may not second-guess the government’s decision “concerning the most appropriate method for promoting significant government interests or the degree to which those interests should be promoted” (internal quotation marks omitted)). But the First Amendment necessarily circumscribes the government’s discretion; a restriction is not “narrowly tailored” simply because it efficaciously serves a significant government interest. “Government may not regulate expression in such a manner that a substantial portion of the burden on speech does not serve to advance its goals.” Id.; see Casey v. City of Newport, 308 F.3d 106, 112 & n. 4 (1st Cir.2002). Accordingly, a content-neutral time, place, or manner regulation will be found to be “narrowly tailored” even if “a court concludes that the government’s interest could be adequately served by some less-speech-restrictive alternative,” “[s]o long as the means chosen are not substantially broader than necessary to achieve [that] interest.” Ward, 491 U.S. at 800, 109 S.Ct. 2746. Our task is to apply this test to the scheme of speech-restrictive zones established by the Ordinance, using the Court’s decisions in Madsen, Schenck, and Hill as guideposts. “The burden is on the City to demonstrate the constitutionality of its actions.” Startzell v. City of Phila., 533 F.3d 183, 201 (3d Cir.2008). Here, the City argues that the Ordinance’s combination of the buffer and bubble zones is narrowly tailored because the two zones are complementary; each serves a different significant interest. The bubble zone “creates a small safety dome,” around entering clinic patients so as to serve the government interest of preventing “persistent, importunity, following and dogging,” Hill, 530 U.S. at 718, 120 S.Ct. 2480. “Because no protester is required to move out of the path of an approaching person” under the bubble zone restrictions, the City maintains that the “15' buffer zone is likewise necessary to ensure unimpeded access to and from clinics.” The buffer zone also “allows the police to have a bright-line test for enforcement to keep doorways open.” Id. In short, the City believes the Ordinance falls within the ambit of discretion afforded by Ward. Brown contends that the Ordinance’s restrictions are not sufficiently tailored to the interests they serve. 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, 530 U.S. at 708 n. 1, 120 S.Ct. 2480 (quoting Colo Rev. Stat. § 18-9-122(2)). In Brown’s view, “[t]his language exemplifies narrow tailoring,” whereas the Ordinance’s addition of the buffer zone excessively burdens speech by precluding any advocacy activities within a fifteen-foot radius of the clinic entrance irrespective of whether those activities actually impede patient access. 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, 530 U.S. at 726-27, 729, 120 S.Ct. 2480, the Court recognized that “[t]he burden on the ability to distribute handbills is more serious because it seems possible that an 8-foot interval could hinder the ability of a leafletter to deliver handbills to some unwilling recipients.” Id. at 727, 120 S.Ct. 2480. In nonetheless finding the Colorado statute constitutional, the Hill Court noted approvingly that the bubble zone allowed leafletters to stand stationary in the path of oncoming pedestrians. Id. at 727-28, 120 S.Ct. 2480. The Court also observed that “demonstrators with leaflets might easily stand on the sidewalk at entrances (without blocking the entrance) and, without physically approaching those who are entering the clinic, peacefully hand them leaflets as they pass by.” Id. at 729-30, 120 S.Ct. 2480. The Court acknowledged that “[s]pecial problems ... may arise where clinics have particularly wide entrances” but determined that these problems were not the appropriate subject of a facial challenge; instead, they “may be worked out as the statute is applied.” Id. at 730, 120 S.Ct. 2480. Because the Ordinance here, unlike the Colorado statute, establishes a fifteen-foot buffer zone around clinic entrances, leafletters cannot stand directly next to the entrance door to ensure arm’s-length access to all entering patients. In this sense, the Ordinance’s buffer zone is analogous to placing very wide entrances on all of the health care facilities covered by the Ordinance. This case therefore appears to present in the context of a facial challenge the problem identified but left unresolved by Hill. According to Brown, the addition of the buffer zone effectively forecloses her ability to leaflet, rendering the Ordinance unconstitutional on its face. 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, 491 U.S. at 800, 109 S.Ct. 2746. The Hill Court allowed the prophylactic bubble zone established by the Colorado statute, even though its restrictions swept up more than the specific incidents of dogging and harassment that were the government’s professed target. Hill, 530 U.S. at 729, 120 S.Ct. 2480. But the Ordinance’s combination of two prophylactic zones here represents a restrictive step beyond the regulation approved in Hill. We must, therefore, apply the Ward test (relied on by Hill) for ourselves, in order to decide whether the Ordinance’s prophylactic measures — which essentially superimpose Schenck’s fifteen-foot buffer zone onto Hill’s one-hundred-foot bubble zone— “burden substantially more speech than is necessary to further the government’s legitimate interests.” Ward, 491 U.S. at 799, 109 S.Ct. 2746. 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, 512 U.S. at 764-65, 114 S.Ct. 2516. But from the standpoint of appellate review, injunctions offer an advantage over generally applicable legislation, as it is easier to determine what is necessary to achieve a significant interest in the context of a specific case, with specific defendants alleged to have engaged in specific conduct. In upholding the fixed buffer-zone injunctions in Mad-sen and Schenck, for example, the Supreme Court relied on the factual findings of the district court regarding defendant protesters’ behavior. “Based on this conduct,” the Supreme Court determined “the District Court was entitled to conclude ... that the only way to ensure access [to the clinic] was to move all protesters away from the doorways.” Schenck, 519 U.S. at 381, 117 S.Ct. 855. Moreover, “because defendants’ harassment of police” in Schenck “hampered the ability of the police to respond quickly to a problem, a prophylactic measure was even more appropriate.” Id. at 382, 117 S.Ct. 855. Here, by contrast, we address a combination of legislatively enacted speech-restrictive zones without support, either in the record or in case law, for the factual proposition that both zones are needed to achieve the City’s legitimate interests in preventing harassment and obstruction of entrances. As “[t]he burden is on the City to demonstrate the constitutionality of its actions,” Startzell, 533 F.3d at 201, we conclude that the Ordinance burdens substantially more speech than necessary and is thus insufficiently tailored. 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 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, 530 U.S. at 729, 120 S.Ct. 2480 (noting that the prophylactic bubble zone relieves police of the need to “focus exclusively on the individual impact of each instance of behavior” and to characterize “each individual movement” made by protesters). 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, 512 U.S. at 758,114 S.Ct. 2516, in order to obtain medical services. 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, 519 U.S. at 377, 117 S.Ct. 855, is especially hard hit by the bubble zone’s enforcement of a space of separation. Although the buffer zone, standing alone, would require leafletters to remain beyond arm’s reach of a medical facilities’ entrances, they would still be able to approach individuals outside of the fifteen-foot radius in order to distribute their literature. With the additional restrictions of the bubble zone, on the other hand, not only are leafletters forbidden from distributing literature within the buffer zone, but they may not approach within eight feet of oncoming pedestrians absent their consent anywhere within one hundred feet of health care facility entrances. As these consequences demonstrate, if the multi-zone Ordinance does not effectively foreclose leafletting entirely, it severely curtails it. In our view, the combination of the two zones burdens substantially more speech than appears necessary, on this record, to achieve the government’s interests. See Ward, 491 U.S. at 800, 109 S.Ct. 2746. 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 prohibited 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, 512 U.S. at 773, 114 S.Ct. 2516. Like the bubble zone here, that zone was designed “to prevent clinic patients ... from being ‘stalked’ or ‘shadowed’ ... as they approached the clinic.” Id. Nonetheless, the Court found “it is difficult, indeed, to justify a prohibition on all uninvited approaches of persons seeking the services of the clinic, regardless of how peaceful the contact may be, without burdening more speech than necessary to prevent intimidation and to ensure access to the clinic.” Id. at 774, 114 S.Ct. 2516. Accordingly, the Court refused to countenance this additional layer of prophylaxis. While acknowledging the serious incidents of disorder and obstruction to which the injunction was addressed, the Court concluded the fixed buffer zone was sufficient to accomplish the government interests at stake; the addition of the no-approach zone was unconstitutionally excessive. 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, 519 U.S. at 377, 117 S.Ct. 855. The Court again found this zone “burden[ed] more speech than is necessary to serve the relevant governmental interests,” in part because it “prevent[ed] defendants ... [from] handing leaflets to people entering or leaving the clinics who are walking on the public sidewalks.” Id. 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. 530 U.S. at 730, 120 S.Ct. 2480. Here, because of the fifteen-foot fixed bubble zone, every entrance is a wide entrance as far as leafletters are concemed-indeed, at least a thirty-foot-wide entrance (assuming the fifteen-foot radius is measured from the very center of the door). We are thus unable to rely, as the Hill Court was, on the prospect that “demonstrators with leaflets might easily stand on the sidewalk at entrances ... and, without physically approaching those who are entering the clinic, peacefully hand them leaflets as they pass by.” Id. at 729-30, 120 S.Ct. 2480. With the Ordinance’s multi-zone restrictions, not only are leafletters unable to stand within fifteen feet of clinic entrances, but they are constrained from moving freely even outside of that protective zone. The fifteen-foot exclusion is a prophylaxis that effectively advances the City’s interests. The additional burden of the bubble zone’s restrictions would be, on this record, unduly' — and unconstitutionally — onerous. Accordingly, we find the Ordinance’s combination of the two zones to be insufficiently tailored under Ward. 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, 260 F.3d at 49-50 (citing Thorburn v. Austin, 231 F.3d 1114, 1122 (8th Cir.2000); Hoover v. Morales, 164 F.3d 221, 227 n. 3 (5th Cir.1998); DLS, Inc. v. City of Chattanooga, 107 F.3d 403, 411 n. 7 (6th Cir.1997)). “So it is here:” each zone of the Ordinance “passes muster under the Equal Protection Clause for the same reasons that it passes muster under the First Amendment.” Id. at 50. 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. See McTernan v. City of York, 564 F.3d 636, 647 (3d Cir.2009) (“The Free Exercise Clause not only forbids regulation of religious beliefs as such but also protects religiously motivated expression.” (citing Employment Div., Dept. of Human Res. of Or. v. Smith, 494 U.S. 872, 877, 110 S.Ct. 1595, 108 L.Ed.2d 876 (1990))). “The Free Exercise Clause, however, does not afford absolute protection to religiously motivated expression.” Id. As the Supreme Court has explained, “a law that is neutral and of general applicability need not be justified by a compelling governmental interest even if the law has the incidental effect of burdening a particular religious practice.” Church of the Lukumi Babalu Aye, Inc. v. Hialeah, 508 U.S. 520, 531, 113 S.Ct. 2217, 124 L.Ed.2d 472 (1993). “A law is ‘neutral’ if it does not target religiously motivated conduct....” Blackhawk v. Pennsylvania, 381 F.3d 202, 209 (3d Cir.2004). It is “generally applicable” if it extends to all conduct that undermines the purposes of the law and does not selectively burden religiously motivated conduct. Combs v. Homer-Center Sch. Dist., 540 F.3d 231, 242 (3d Cir.2008) (per curiam) (citing Blackhawk, 381 F.3d at 209). Under the Supreme Court’s decision in Smith, a neutral, generally applicable law is subject only to rational-basis review, which “requires merely that the action be rationally related to a legitimate government objective.” Tenafly Eruv Ass’n v. Tenafly, 309 F.3d 144,165 n. 24 (3d Cir.2002). 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. 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 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, 540 F.3d at 260-61 (Scirica, C.J., concurring) (discussing “the development of federal First Amendment jurisprudence and its influence on Pennsylvania law”). As noted, under the Supreme Court’s holding in Smith, neutral, generally applicable laws burdening religion are subject only to rational-basis scrutiny under the Federal Constitution’s Free Exercise Clause. The RFPA, by contrast, prohibits any law from “substantially burden[ing] a person’s free exercise of religion,” even if the “burden ... results from a rule of general applicability,” unless the law is the least restrictive means of furthering a compelling state interest. 71 Pa. Stat. Ann. § 2404. 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, 540 F.3d at 262 (Scirica, C.J., concurring). In addition, the RFPA requires “as a threshold matter” that persons invoking its protections “prove ... that their free exercise of religion has or will likely be ‘substantially burdened’ ” by “clear and convincing evidence”; only after that showing is made is the government obliged to demonstrate that the challenged law or activity is the least restrictive means of advancing a compelling interest. Id. at 253 (per curiam opinion); see also id. at 262 (Scirica, C.J., concurring) (“[B]y requiring proof of a ‘substantial burden’ by clear and convincing evidence, Pennsylvania appears to have set a higher threshold than other religious restoration statutes.”); Commonwealth v. Parente, 956 A.2d 1065, 1074 n. 16 (Pa.Commw.Ct.2008) (noting that the Pennsylvania Supreme Court has stated that “[t]he standard of clear and .convincing evidence means testimony that is so clear, direct, weighty, and convincing as to enable the trier of fact to come to a clear conviction, without hesitancy, of the truth of the precise facts in issue” (quoting In re Sylvester, 521 Pa. 300, 555 A.2d 1202, 1203-04 (1989))). 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. 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., 515 U.S. 819, 829, 115 S.Ct. 2510, 132 L.Ed.2d 700 (1995) (“The government must abstain from regulating speech when the specific motivating ideology ... is the rationale for the restriction.”). 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., 459 Pa. 450, 329 A.2d 812, 827 (1974) (quoting Crowell v. Benson, 285 U.S. 22, 62, 52 S.Ct. 285, 76 L.Ed. 598 (1932)). This principle applies with equal force to the interpretation of municipal ordinances. See Dole v. Philadelphia, 337 Pa. 375, 11 A.2d 163, 168 (1940); Kadash v. City of Williamsport, 19 Pa.Cmwlth. 643, 340 A.2d 617, 621 (1975). In accordance with this precept, we construe the statutory scheme at issue here in a manner that preserves it from serious constitutional doubt: the Ordinance’s restrictions do not “substantially burden” religiously motivated expression if they do not impose an impermissible burden under the Free Speech Clause of the First Amendment. 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, 374 U.S. 398, 83 S.Ct. 1790, 10 L.Ed.2d 965 (1963), before the Supreme Court decided Employment Division v. Smith. See supra note 26; Pa. Senate Journal, 2002 Reg. Sess. No. 67, at 2386 (Nov. 20, 2002) (statement of Sen. Jubelirer, co-sponsor of the RFPA); id. at 2386-87 (statement of Sen. Mellow, co-sponsor of the RFPA). In the Sherbert era, the Supreme Court confronted a free exercise challenge to a rule confining solicitation at state fairs to booths. See Heffron, 452 U.S. 640, 101 S.Ct. 2559; of. Navajo Nation v. U.S. Forest Serv., 535 F.3d 1058, 1074 (9th Cir.2008) (looking to Sherbert-era Supreme Court cases in interpreting the federal Religious Freedom Restoration Act). The Court held that the rule did not unconstitutionally restrict the plaintiffs right to freely exercise “one of its religious rituals, which enjoins its members to go into public places to ... solicit donations for the support of the Krishna religion,” because the rule was valid under the Court’s test for time, place, and manner restrictions on expression. Hejfron, 452 U.S. at 645, 101 S.Ct. 2559. Heffron suggests that where the religious exercise in question is also expression protected by the Free Speech Clause of the First Amendment, the protection afforded by the Free Exercise Clause — under the earlier “substantial burden” test of Sherbert, which the RFPA seeks to restore — is congruent with the protection provided by the Free Speech Clause. Indeed, this is precisely the gloss a concurring opinion gave to Hejfron at the time: Our cases are clear that governmental regulations which interfere with the exercise of specific religious beliefs or prin
