OPINION

We must decide whether a state statute prohibiting sexually-oriented businesses from operating during late night hours passes muster under the First Amendment.

I

The Arizona statute at issue here requires all sexually-oriented businesses 1 to close “between the hours of 1.00 a.m. and 8:00 a.m. on Monday through Saturday and between the hours of 1:00 a.rn. and 12:00 noon on Sunday.” Ariz.Rev.Stat. § 13-1422(A). A sexually-oriented business is an “adult arcade, adult bookstore or video store, adult cabaret, adult motion picture theater, adult theater, escort agency or nude model studio....” Id. Violation of § 13-1422(A) is a class one misdemean- or. Id. § 13-1422(B).

Section 13-1422 was originally proposed to the Arizona legislature in 1998 as Senate Bill 1367. The bill was assigned to the House of Representatives’ Government Reform and States’ Rights Committee and to the Senate Family Services Committee, and public hearings were held in both bodies. While the original bill passed in the Senate, it was voted down in the Arizona House Rules Committee.

At the same time, Senate Bill 1162, a bill authorizing Arizona counties to develop land-use regulations within their respective jurisdictions, and which included an authorization to license and to regulate sexually-oriented businesses operating within unincorporated areas, was winding its way through the legislature. When original Senate Bill 1367 failed in the House Rules Committee, its provisions were added verbatim as an amendment to the more comprehensive Senate Bill 1162. Amended Senate Bill 1162 passed both the House and the Senate, and was signed into law on June 1, 1998, and became effective on August 21,1998.

The record before the Arizona legislature prior to § 13-1422’s enactment consisted of testimonial evidence from several individuals, as well as some limited documentary evidence with respect to the need for restricting sexually-oriented businesses’ hours of operation.

Russell Smolden and Jane Lewis both testified before House and Senate committees. These individuals worked for mixed-use real estate parks located in Tempe and Phoenix, and both testified that nearby sexually-oriented businesses were disruptive of their attempts to attract new employers to the parks, and prospective employers expressed concern for their employees who worked night-shifts. They testified that limiting the hours of operation of the nearby sexually-oriented businesses would aid in then* efforts to attract employers to the parks.

Scott Bergthold, the executive director and general counsel to the National Family Legal Foundation (“NFLF”), testified that similar hours of operation restrictions had been upheld as constitutional by federal courts. He also testified that approximately fifteen studies had been conducted concerning the negative secondary effects associated with sexually-oriented businesses. Those studies documented increased crime, prostitution, public sexual indecency and health risks associated with HIV and AIDS transmission.

Donna Neil, co-founder of a group known as the Neighborhood Activist Inter *1158 linked Empowerment Movement (“Nail’em”), testified that, each weekend, parents in her neighborhood cleared up litter emanating from neighborhood sexually-oriented businesses. She also testified that the local school’s playground was fenced and closed to neighborhood children on weekends due to incidents of prostitution on school grounds. She stated that the neighborhood had experienced an increase in crime — specifically drug arrests and assaults — associated with sexually-oriented businesses. Finally, Bridget Mannock, a neighborhood legislative liaison for the City of Phoenix testified that a state-level hours of operation regulation was necessary due to the limited nature of the local municipalities’ authority.

Some documentary evidence was presented to the Arizona legislature. First, there is a letter from the NFLF addressed to the House Government Reform and States’ Rights Committee. The letter discussed the acute problems associated with sexually-oriented businesses as documented in a report from the Denver Metropolitan Police Department, which concluded that sexually-oriented businesses “disproportionately deplete police time and resources during the overnight hours.” The Denver report itself was not presented to the Committée. The letter also discussed the fact that the proposed regulation was constitutional because it was a reasonable time, place and manner -restriction on speech. Second, there is a letter from the NFLF to House members, discussing ostensibly the same themes raised in the letter to the House Committee. Finally, there is a “fact sheet” prepared by the NFLF, which noted that every study conducted established the negative secondary effects associated with, sexually-oriented businesses. In particular, the fact sheet noted a 1989 report prepared by the Minnesota Attorney General’s office which concluded that surrounding communities are negatively impacted by 24-hour-a-day or late night operation of sexually-oriented businesses. None of the reports discussed in the fact sheet were presented to the legislature. The fact sheet also contained a discussion of the constitutionality of the proposed restrictions.

The plaintiffs in this action are owners and operators of sexually-oriented businesses in Arizona. They include nude-dancer clubs, x-rated video arcades and sellers of sexually-related magazines and paraphernalia. Some of these businesses were open 24-hours a day prior to enactment of § 13-1422. Two separate groups of plaintiffs — the L.J. Concepts, Inc. plaintiffs and the Center for Fair Public Policy plaintiffs (collectively “Fair Public Policy”) — filed suit on September 1, 1998 in federal district court, alleging that § 13-1422 violates the First Amendment, and seeking declaratory and injunctive relief. The cases were consolidated and assigned to Judge Carroll, and a briefing schedule with respect to the propriety of issuing a preliminary injunction was agreed upon.

While the parties were briefing the preliminary injunction issue, the state defendants placed in the district court record copies of fourteen studies on the negative secondary effects associated with adult-oriented businesses. Fair Public Policy objected because these studies were not before the legislature prior to § 13-1422’s enactment.

On September 30, 1999, Judge Carroll denied Fair Public Policy’s application for a preliminary injunction. The district court found that the statute was constitutional under the Supreme Court’s decision in Renton v. Playtime Theatres, Inc., 475 U.S. 41 , 106 S.Ct. 925 , 89 L.Ed.2d 29 (1986), and that there was sufficient pre-enactment evidence, without regard to the studies introduced during the litigation, to support the statute’s enactment. The plaintiff groups filed notices of appeal from *1159 Judge Carroll’s decision, and those appeals were duly consolidated by this court. We affirmed the district court’s decision not to issue a preliminary injunction. See L.J. Concepts v. City of Phoenix, No. 99-17270, 2000 U.S.App. LEXIS 5906, at *3 (9th Cir. March 30, 2000). On September 13, 1999, the district court denied the plaintiffs’ request for a permanent injunction and declaratory relief, and entered judgment for the defendants. Plaintiffs timely appealed.

II

While the constitutionality of hours of operation restrictions on sexually-oriented businesses is an issue of first impression in this circuit, six other circuits have had occasion to consider similar restrictions, and all have found such restrictions to be constitutional under the “secondary effects” test first enunciated by the Supreme Court in Renton. See DiMa Corp. v. Town of Hallie, 185 F.3d 823 (7th Cir.1999); Lady J. Lingerie, Inc. v. City of Jacksonville, 176 F.3d 1358 (11th Cir.1999); Richland Bookmart Inc. v. Nichols, 137 F.3d 435 (6th Cir.1998); Nat’l Amusements Inc. v. Town of Dedham, 43 F.3d 731 (1st Cir.1995); Mitchell v. Comm’n on Adult Enter. Est. of the State of Delaware, 10 F.3d 123 (3d Cir.1993); Star Satellite, Inc. v. City of Biloxi, 779 F.2d 1074 (5th Cir.1986).

In Renton , the Supreme Court considered a constitutional challenge to a zoning ordinance prohibiting adult movie theaters from locating within 1,000 feet of any residential zone. 475 U.S. at 43 , 106 S.Ct. 925 . Citing its decision in Young v. American Mini Theatres, Inc., 427 U.S. 50 , 96 S.Ct. 2440 , 49 L.Ed.2d 310 (1976), the Court established a now familiar three-part analytical framework for evaluating the constitutionality of sexually-oriented business regulations, or what Professor Tribe has described rather aptly as “erogenous zoning laws.” Laurence H. Tribe, American Constitutional Law 934 (2d ed.1988). First, the Court asked whether the ordinance was a complete ban on adult theaters. Id. at 46, 106 S.Ct. 925 . Because the ordinance was not a total ban, it was properly analyzed as a time, place and manner regulation. Id. Second, the Court considered whether the ordinance was content neutral or content based. The Court held that, because the ordinance at issue was aimed not at the content of the films shown at adult theaters, but rather at the secondary effects such theaters have on the surrounding community, it was properly classified as content neutral. Id. at 47 , 106 S.Ct. 925 . Third, given this finding, the final step is to ask whether the ordinance is designed to serve a substantial government interest and that reasonable alternative avenues of communication remain available. Id. at 50 , 106 S.Ct. 925 . With respect to the burden of proof at this stage, the Court held that the First Amendment “does not require a city ... to conduct new studies or produce evidence independent of that already generated by other cities, so long as whatever evidence the city relies upon is reasonably believed to be relevant to the problem that the city addresses.” Id. at 51-52 , 106 S.Ct. 925 .

A

The Supreme Court recently reaffirmed the Renton framework in City of Los Angeles v. Alameda Books, Inc., 535 U.S. 425 , 122 S.Ct. 1728 , 152 L.Ed.2d 670 (2002). At issue in that case was a Los Angeles ordinance prohibiting multiple adult entertainment businesses from operating in the same building. In enacting this ordinance, the city primarily relied on a 1977 study conducted by the city’s planning department, which indicated that between 1965 and 1975, crime had grown at a much higher rate in Hollywood, which had the largest concentration of adult establishments in the city, than in the city as a whole. Id. at 435 , 122 S.Ct. 1728 (plurality *1160 opinion). Under the third prong of the Renton analysis, we had found that the 1977 study did not reasonably support the inference that a concentration of adult operations in the same building produced higher crime rates. See Alameda Books, Inc. v. City of Los Angeles, 222 F.3d 719, 725 (9th Cir.2000). This was so, we held, because the study focused on the effect of a concentration of establishments on a given area, not on the effect of a concentration of establishments within a single building. Id. It was therefore unreasonable, we opined, for the city to infer that absent its regulation, a combination of establishments within a single building would have harmful secondary effects on the surrounding community. Id.

The Supreme Court reversed. Writing for a four-judge plurality, Justice O’Con-nor wrote that we had erred in requiring the city to “prove that its theory about a concentration of adult operations ... is a necessary consequence of the 1977 study.” 535 U.S. at 437 , 122 S.Ct. 1728 (emphasis added). Justice O’Connor explained,

Id. at 438-39, 122 S.Ct. 1728 (internal citation and quotation omitted).

The plurality made two other points of clarification with respect to the evidentiary burden under Renton . First, it rejected the notion that the state is required to come forward with empirical data in support of its ordinance. “Such a requirement,” wrote Justice O’Connor, “would go too far in undermining our settled position that municipalities must be given a reasonable opportunity to experiment with solutions to address the secondary effects of protected speech.” Id. at 439, 122 S.Ct. 1728 .

Second, the plurality made it clear that “the inquiry into whether a [sexually-oriented business regulation] is content neutral” and the “inquiry into whether it is designed to serve a substantial government interest” are separate and distinct. Id. at 440 , 122 S.Ct. 1728 (quotation and internal citation omitted). Justice O’Con-nor explained,

*1161 Id. at 440-41, 122 S.Ct. 1728 (quoting Renton, 475 U.S. at 47 , 106 S.Ct. 925 ) (alterations in original).

Writing separately, Justice Kennedy concurred in the judgment. Because his concurrence is the narrowest opinion joining in the judgment of the Court, Justice Kennedy’s concurrence may be regarded as the controlling opinion. See Marks v. United States, 430 U.S. 188 , 193, 97 S.Ct. 990 , 51 L.Ed.2d 260 (1976) (“When a fragmented Court decides a case and no single rationale explaining the result enjoys the assent of five Justices, the holding of the Court may be viewed as that position taken by those Members who concurred in the judgment on the narrowest grounds.”) (citation and internal quotation omitted).

In his separate concurrence, Justice Kennedy agreed with the plurality that “the central holding of Renton is sound: A zoning restriction that is designed to decrease secondary effects and not speech should be subject to intermediate rather than strict scrutiny.” 535 U.S. at 448 , 122 S.Ct. 1728 (Kennedy, J., concurring). Justice Kennedy wrote separately, he explained, for two distinct reasons.

First, he agreed with the four dissenting justices that sexually-oriented business regulations should no longer be designated as “content neutral” when they were clearly not. Whether a statute is content based or content neutral, he explained, “is something that can be determined on the face of it; if the statute describes speech by content then it is content based.” Id. Classifying regulations of the type at issue in Renton and Alameda Books as content neutral, explained Justice Kennedy, was an unhelpful legal fiction which only leads to doctrinal incoherence; these types of ordinances “are content based and we should call them so.” Id.

Second, while Justice Kennedy agreed with the plurality that Renton remained sound, he wrote separately because in his view, the plurality’s application of Renton “might constitute a subtle expansion” of Renton’s principles with which he did not agree. Id. at 445, 122 S.Ct. 1728 . He explained that, in his view, the question presented' — -whether or not the city could rely on judicially approved statutory precedent from other jurisdictions in support of the regulation — “is actually two questions.” 535 U.S. at 449 , 122 S.Ct. 1728 .

Id. With regard to the first question- — the proposition that the city needs to advance — Justice Kennedy wrote that “a city may not assert that it will reduce secondary effects by reducing speech in the same proportion.” Id. The analysis has to address “how speech will fare under the ... ordinance.” Id. at 450 , 122 S.Ct. 1728 . Because of this, “it does not suffice to say that inconvenience will reduce demand and fewer patrons will lead to fewer secondary effects.” Id. The rationale, therefore, has to be that a proposed secondary-effects ordinance will leave “the quantity of speech ... substantially undiminished, and that total secondary effects will be significantly reduced.” Id. at 451 , 122 S.Ct. 1728 . To illustrate this proportionality requirement, Justice Kennedy took the facts of the case under consideration,

Id. at 451 , 122 S.Ct. 1728 .

Only after identifying “the proposition to be proved” can a court seek to answer “the second part of the question presented; is there sufficient evidence to support the proposition?” Id. As to the state’s eviden-tiary burden, Justice Kennedy agreed fully with the plurality that “very little evidence is required.” Id. The “reasonable reliance” standard is necessary, he wrote, because “[a]s a general matter, courts should not be in the business of second-guessing fact-bound empirical assessments of city planners.” Id.

2

Going straight for the jugular, Fair Public Policy pounces on Justice Kennedy’s concurrence in Alameda Books and argues that there is no way to reconcile the statute at issue here with his “proportionality” requirement. It argues that sexually-oriented businesses draw a fair amount of their patronage in the evening and late night hours — nude dancing establishments are hardly doing a roaring trade after dawn. The ordinance shuts these establishments down during the late night hours, and therefore it cannot be, as Justice Kennedy would require, that “the quantity of speech will be substantially undiminished, and that total secondary effects will be significantly reduced.” Id. This is precisely the scenario Justice Kennedy warned against, Fair Public Policy argues, because it is only by reducing the enjoyment of protected expression that the state reduces secondary effects. Because the statute cannot be squared with Justice Kennedy’s proportionality analysis, and because his is the controlling opinion under Marks, it urges that the statute must be invalid under the First Amendment.

a

Fair Public Policy’s argument is a forceful one, but there are several reasons that lead us to conclude that Justice Kennedy never intended a heightened proportionality requirement to apply in this particular context. First and foremost, the argument that Justice Kennedy meant to invalidate an hours of operation restriction of the type at issue here cannot be squared with his insistence that “the central holding of Renton remains sound.” Id. at 448, 122 S.Ct. 1728 . Limiting the negative ex-ternalities associated with certain land uses, as a properly crafted secondary effects ordinance is designed to do, is a “prima facie legitimate purpose,” and for this reason “such laws do not automatically raise the specter of impermissible content discrimination.” Id. at 449 , 122 S.Ct. 1728 . Justice Kennedy quite clearly agreed with the plurality that laws “designed to decrease secondary effects ... should be subject to intermediate rather than strict scrutiny.” Id. at 449 , 122 S.Ct. 1728 . He wrote separately to guard against “a subtle expansion” of Renton , and not, as Fair Public Policy would have it, to signal a fundamental shift in the Renton 10229 framework. Given his emphatic reaffir-mance of Renton , we are not persuaded that Justice Kennedy meant to precipitate a sea change in this particular corner of First Amendment law. This is especially so given that the circuit courts have thus far been unanimous in upholding similar or even more severe hours of operation restrictions under Renton. See DiMa Corp., 185 F.3d 823 ; Lady J. Lingerie, Inc., 176 F.3d at 1358 ; Richland Bookmart Inc., 137 F.3d at 435 ; Nat’l Amusements Inc., 43 F.3d at 731 ; Mitchell, 10 F.3d at 123 ; Star Satellite, Inc., 779 F.2d at 1074 . We *1163 read nothing in Justice Kennedy’s separate opinion signaling disapproval with these results.

b

Justice Kennedy’s proportionality analysis also needs to be understood in light of the particular species of secondary effects law that the Court was considering. The ordinance at issue in Alameda Books was a classic erogenous zoning ordinance whereby the city was restricting certain land uses. It was a “place” restriction, and Justice Kennedy’s proportionality analysis is easy enough to understand and to apply to such a typical zoning ordinance. The city’s rationale cannot be that when it requires businesses to disperse (or to concentrate), it will force the closure of a number of those businesses, thereby reducing the quantity of protected speech. In contrast, we are faced with a quite different species of secondary effects law — a “time” restriction that forces the closure of all adult entertainment establishments for a limited time. We accept the proposition that such establishments tend to be patronized in the evening and late at night. Given this, the application of Justice Kennedy’s proportionality analysis to this particular type of secondary effects law would invalidate all such laws, and we are satisfied that he never intended such a result. His proportionality requirement was simply not designed with this particular type of restriction in mind.

c

Finally, Fair Public Policy’s argument that Justice Kennedy’s Alameda Books opinion presents a new and different approach to the constitutional analysis of secondary effects law is inconsistent with the weight of authority in the wake of that decision. Courts have routinely upheld properly crafted secondary effects ordinances supported by a proper record in the wake of Alameda Books, and have explicitly stated that Justice Kennedy’s separate decision did little, if indeed anything, to the traditional Renton framework. See Z.J. Gifts D-4, LLC v. City of Littleton, 311 F.3d 1220 , 1239 n. 15 (10th Cir.2002) (seeing “nothing in ... Alameda Books that requires reconsideration” of the traditional Renton framework); World Wide Video of Wash., Inc. v. City of Spokane, 227 F.Supp.2d 1143 , - (E.D.Wash.2002) (“While Alameda Books may clarify existing precedent, this court is not persuaded that it fundamentally alters the legal landscape regarding adult entertainment zoning ordinances.”). As the Seventh Circuit explained, “[t]he differences between Justice Kennedy’s concurrence and the plurality opinion are ... quite subtle.” Ben’s Bar, Inc. v. Village of Somerset, 316 F.3d 702, 721 (7th Cir.2003).

Id. (emphasis in original) (quoting Alameda Books, 535 U.S. at 450 , 122 S.Ct. 1728 (Kennedy, J., concurring)). Indeed, the plurality in Alameda Books considered Justice Kennedy’s proportionality analysis “unobjectionable,” and “simply a reformulation of the requirement that an ordinance warrants intermediate scrutiny only if it is a time, place, and manner regulation and not a ban.” 535 U.S. at 443 , 122 S.Ct. 1728 (plurality opinion).

d

In any event, to the extent Justice Kennedy’s concurrence worked any change in the traditional Renton framework, we are satisfied that his proportionality analysis *1164 does not apply to the particular type of regulation that we deal with here, and we reject Fair Public Policy’s argument that the statute must be invalidated on the basis of his opinion. Because five members of the Supreme Court agreed that “the central holding of Renton is sound” we apply the traditional three-part test in order to determine the constitutionality of § 13-1422.

B

Our first task under Renton , then, is to determine whether the statute amounts to a complete ban on protected expressive activity. Renton, 475 U.S. at 46 , 106 S.Ct. 925 ; Alameda Books, 535 U.S. at 434 , 122 S.Ct. 1728 (plurality opinion).

1

The statute at issue here is obviously not a complete ban. It is a classic time, place or manner restriction, prohibiting sexually-oriented businesses from operating during certain nighttime hours, and until noon on Sundays. The businesses may remain open the remainder of the time, 115 hours in a 168 hour week, or approximately 5,980 hours in a calendar year. “The ordinance is therefore properly analyzed as a time, place, and manner regulation.” Renton, 475 U.S. at 46 , 106 S.Ct. 925 .

2

Next, we must determine what level of scrutiny to apply. Traditionally, the Court has invoked the content based/content neutral distinction as the basis for determining which level of scrutiny to apply. See Turner Broadcasting Sys., Inc. v. FCC, 512 U.S. 622, 642 , 114 S.Ct. 2445 , 129 L.Ed.2d 497 (1994) (“Our precedents ... apply the most exacting scrutiny to regulations that suppress, disadvantage, or impose differential burdens upon speech because of its content.... In contrast, regulations that are unrelated to the content of speech are subject to an intermediate level of scrutiny.”).

A regulation restricting the hours of operation of a sexually-oriented business is quite obviously content based. “[Wlhether a statute is content neutral or content based is something that can be determined on the face of it; if the statute describes speech by content then it is content based.” Alameda Books, 535 U.S. at 448 , 122 S.Ct. 1728 (Kennedy, J., concurring). The Arizona statute is content based on its face because whether an establishment falls within its parameters, and is therefore subject to sanction for violating the prohibition against operating during nighttime hours, can only be determined by reference to the content of the expression inside it. See Schultz v. City of Cumberland, 228 F.3d 831 , 843-44 (7th Cir.2000) (“[A]n ordinance that regulates only adult-entertainment businesses singles out adult-oriented establishments for different treatment based on the content of the materials they sell or display.”) (internal quotation omitted). Because the statute is content based, Fair Public Policy argues that strict scrutiny should apply. Such argument is misplaced.

The Supreme Court has clearly carved out sexual and pornographic speech as one type of speech than can be subject to reasonable restriction. “Generally, the government has no power to restrict speech based on content, but there are exceptions to this rule.” Alameda Books, 535 U.S. at 448 , 122 S.Ct. 1728 (Kennedy, J., concurring). The speech and expressive activity at issue here is one such exception; the content based/content neutral distinction simply does not fit in this context. In fine, so long as the regulation is designed to combat the secondary effects of such establishments on the surrounding community, “namely at crime rates, property values, and the quality of the city’s neighborhoods,” Alameda Books, *1165 535 U.S. at 434 , 122 S.Ct. 1728 (plurality opinion), then it is subject to intermediate scrutiny. See also Colacurcio v. City of Kent, 163 F.3d 545, 551 (9th Cir.1998) (explaining that if “the predominant purpose” of an ordinance is ameliorating secondary effects associated with sexually-oriented businesses, then it is subject to intermediate scrutiny).

“We will look to the full record” to determine whether the purpose of the statute is to ameliorate secondary effects. Id. at 552 . “In so doing, we will rely on all ‘objective indicators of intent,’ including the ‘face of the statute, the effect of the statute, comparison to prior law, facts surrounding enactment, the stated purpose, and the record of proceedings.’ ” Id. (quoting City of Las Vegas v. Foley, 747 F.2d 1294, 1297 (9th Cir.1984)).

a

In this context, the first thing to note about § 13-1422 is that it regulates both establishments protected by the First Amendment — adult bookstores, video stores, cabarets, motion picture theaters and theaters — and businesses that have no such protection — escort agencies, 2 for example, suggesting that the state’s purpose in enacting the statute was unrelated to the suppression of expression. In Alameda Books , Justice Kennedy noted the fact that the ordinance at issue was “not limited to expressive activities. It also extends ... to massage parlors, which the city has found to cause similar secondary effects.” 535 U.S. at 447 , 122 S.Ct. 1728 (Kennedy, J., concurring).

Furthermore, the hours regulation was passed as an amendment to Senate Bill 1162, a broader bill authorizing counties to develop comprehensive land-use regulations within their respective jurisdictions, and to promote the social value of the land as a whole. See Ariz.Rev.Stat. § 11-821 (“The county plan shall be made with the general purpose of guiding and accomplishing a coordinated, adjusted and harmonious development of the area of jurisdiction.”). This is yet another objective indicator that the purpose of the statute was to combat the negative secondary effects associated with sexually-oriented businesses. See Alameda Books, 535 U.S. at 447 , 122 S.Ct. 1728 (Kennedy, J., concurring) (fact that the ordinance at issue was “one part of an elaborate web of land-use regulations_suggests that the ordinance is more in the nature of a typical land-use restriction and less in the nature of a law suppressing speech”).

There are other “objective indicators of intent” on this record. Foley, 747 F.2d at 1297 . For example, the “fact sheet” prepared by the NFLF stated that a statewide hours regulation was necessary to curb the problems associated with sexually-oriented business, which “according to law enforcement, include noise, traffic, unlawful public sexual activity, prostitution and drug trafficking.” Moreover, the majority of comments made by legislators when the bill was under consideration focused on the secondary effects associated with sexually-oriented businesses. In short, our examination of the record as a whole, see Colacurcio, 163 F.3d at 552 , indicates that the predominant purpose in enacting this provision was to ameliorate the secondary effects associated with the regulated establishments.

*1166 b

Fair Public Policy argues that there is no pre-enactment evidence on which the legislature could rely to support its conclusion that the restrictions are warranted. But this argument confuses two separate issues which the Supreme Court has made clear need to be carefully distinguished. The ‘predominant purpose’ inquiry is separate and independent from the inquiry into whether the statute is designed to serve a substantial government interest. Only with respect to the latter inquiry “did Renton contemplate that courts would examine evidence concerning regulated speech and secondary effects.” Alameda Books, 535 U.S. at 441 , 122 S.Ct. 1728 (plurality opinion). In short, Fair Public Policy’s argument'is one that was specifically considered and rejected by the Supreme Court in Alameda Books . Because our examination of the record as a whole indicates that, in enacting the hours of operation restriction, the Arizona legislature was concerned with curbing the negative secondary effects associated with such businesses, intermediate scrutiny applies.

3

The statute will be upheld if it is designed to serve a substantial government interest, is narrowly tailored to serve that interest, and does not unreasonably limit alternative avenues ' of communication. Renton, 475 U.S. at 50 , 106 S.Ct. 925 ; Colacurcio, 163 F.3d at 551 .

a

It is beyond peradventure at this point in the development of the doctrine that a state’s interest in curbing the secondary effects associated with adult entertainment establishments is substantial. See Young, 427 U.S. at 71 , 96 S.Ct. 2440 (city’s “interest in attempting to preserve the quality of urban life is one that must be accorded high respect”); Renton, 475 U.S. at 50 , 106 S.Ct. 925 (noting the “vital government interests at stake”); Alameda Books, 535 U.S. at 435 , 122 S.Ct. 1728 (“reducing crime is a substantial government interest”).

Here, Arizona’s specific interest is in reducing the secondary effects associated with late night operations of sexually-oriented businesses, which include noise, traffic, unlawful public sexual activity, prostitution and drug trafficking. Each of our sister circuits to have considered similar prohibitions has recognized that such an interest is a substantial one. See, e.g., National Amusements, Inc., 43 F.3d at 741 (city has a substantial interest in preserving peace and tranquility for citizens during late evening hours); Mitchell, 10 F.3d at 133 (state’s interest in preserving character and preventing deterioration of neighborhoods substantial); Richland Bookmart, Inc., 137 F.3d at 440-41 (deterring “prostitution in the neighborhood at night or the creation of ‘drug corners’ on the surrounding streets” a substantial government interest).

The critical issue, of course, is whether the state has met its burden under Renton of coming forward with evidence that “demonstrate[s] a connection between the speech regulated ... and the secondary effects that motivated the adoption of the ordinance.” Alameda Books, 535 U.S. at 441 , 122 S.Ct. 1728 (plurality opinion). 3

*1167 The pre-enactment record is a slim one, and consists of certain letters from NFLF documenting in a general sense the “acute problems” associated with sexually-oriented businesses, and discussing a Denver, Colorado study, which concluded that such establishments disproportionately deplete police time and resources during overnight hours. A “fact sheet” distributed to legislatures cited fourteen studies that documented the secondary-effects associated with adult entertainment establishments, and in particular it noted a Minnesota study establishing specific secondary effects associated with sexually-oriented businesses during overnight hours. The Arizona legislature also held public hearings and considered certain testimonial evidence, including evidence that prospective employers were concerned for the safety of their night-shift employees, and testimony from a neighborhood activist concerning the litter, prostitution, and drug use in her neighborhood.

All of the evidence the Arizona legislature considered fairly supports its rationale that prohibiting sexually-oriented businesses from operating in the late night hours will lead to a reduction in secondary effects, and generally enhance the quality of life for Arizona citizens. A comparison of the record before the Arizona legislature to the record amassed in prior cases that have been the subject of judicial scrutiny may be helpful in determining whether the state has carried its burden in this case. The quantum and quality of evidence here compares unfavorably to two of the circuit court cases to have considered similar restrictions. The city ordinance upheld by the Fifth Circuit was “adopted after extensive study” by the city. Star Satellite, Inc., 779 F.2d at 1077-78 . No such study was done here. Instead, Arizona relied on the experiences of other communities in support of its rationale. But see Renton, 475 U.S. at 50 , 106 S.Ct. 925 (rejecting the argument that it was necessary for a city to conduct its own studies). The ordinance at issue in Schultz v. City of Cumberland, 228 F.3d 831 , 846 (7th Cir.2000) was adopted after the city “collected and reviewed a host of studies,” and here, while the legislature was briefed with respect to certain studies, no studies were put before the legislature prior to enactment.

The record compares favorably to the evidence considered in several other cases, however. In Mitchell , lawmakers “received no documents or any sworn testimony in support of the bill” and “the General Assembly did not conduct public hearings.” 10 F.3d at 133 . Nonetheless the Third Circuit held that the state had met its evidentiary burden under Renton. See also DiMa Corp., 185 F.3d at 830-31 (city relied on factual record supporting another city’s ordinance); Ben Rich Trading Inc., 126 F.3d at 161 (only thing city relied on was evidence presented to state legislature two years previously).

*1168 The record here is hardly overwhelming, but it does not have to be. See Alameda Books, 535 U.S. at 451 , 122 S.Ct. 1728 ,(Kennedy, J., concurring) (“very little evidence is required” to justify a secondary effects ordinance). The question is whether the Arizona legislature relied on evidence “reasonably believed to be relevant” in demonstrating a connection between its stated rationale and the protected speech, and we hold that it has done that here. The Arizona Senate and House held public hearings at which lawmakers heard citizen testimony concerning the late night operation of sexually-oriented businesses, and were briefed on several studies documenting secondary effects, and two of those studies were specific to late night operations. See Renton, 475 U.S. at 50 , 106 S.Ct. 925 (reasonable for regulators to rely on experiences and studies of other cities, as well as legal decisions upholding similar regulations). That evidence is both reasonable and relevant, and compares favorably with the evidence presented in other cases.

Under Alameda Books , the burden now shifts to Fair Public Policy to “cast direct doubt on [the state’s] rationale, either by demonstrating that the [state’s] evidence does not support its rationale or by furnishing evidence that disputes the [state’s] factual findings.” 535 U.S. at 441 , 122 S.Ct. 1728 (plurality opinion). Fair Public Policy’s primary argument on appeal is that the evidence before the Arizona legislature consisted of “irrelevant anecdotes” and “isolated” incidents, and that testimonial evidence is not “real” evidence. If Fair Public Policy means to argue that such evidence is improper, its argument is erroneous, and simply misconstrues the nature of the legislative process. Legislative committees are not judicial tribunals, and they are not bound by rules of evidence. As the First Circuit explained when confronted with a similar argument,

National Amusements, Inc., 43 F.3d at 742 (internal quotation and citations omitted); see also World Wide Video of Wash., 227 F.Supp.2d 1143 (“[A]necdotal evidence and reported experience can be as telling as statistical data and can serve as a legitimate basis for finding negative secondary effects.”) (quoting Stringfellow’s of N.Y., Ltd. v. City of New York, 91 N.Y.2d 382 , 671 N.Y.S.2d 406 , 694 N.E.2d 407, 417 (1998)).

To the extent Fair Public Policy argues that the state needs to come forward with empirical data in support of its rationale, that argument was specifically rejected in Alameda Books. 535 U.S. at 439 , 122 S.Ct. 1728 (plurality opinion) (“Such a requirement would go too far in undermining our settled position that municipalities must be given a reasonable opportunity to experiment with solutions to address the secondary effects of protected speech.”) (internal quotation omitted); see also Barnes v. Glen Theatre, Inc., 501 U.S. 560, 584 , 111 S.Ct. 2456 , 115 L.Ed.2d 504 (Souter, J., concurring) (“legislation seeking to combat the secondary effects of adult entertainment need not await localized proof of those effects”).

Fair Public Policy has faded to cast doubt on the state’s theory, or on the evidence the state relied on in support of that theory. “Precedent ... commands *1169 that courts should not stray from a deferential standard in these contexts, even when First Amendment rights are implicated through secondary effects.” Charter Comm’s, Inc. v. County of Santa Cruz, 304 F.3d 927, 932 (9th Cir.2002). Since the state relied on evidence that is “reasonably believed to be relevant,” Renton, 475 U.S. at 52 , 106 S.Ct. 925 , we are satisfied that it has met its evidentiary burden.

The narrow tailoring requirement is satisfied so long as the government’s asserted interest “would be achieved less effectively absent the regulation.” Colacurcio, 163 F.3d at 553 (quoting Ward v. Rock Against Racism, 491 U.S. 781, 799 , 109 S.Ct. 2746 , 105 L.Ed.2d 661 (1989)).

It appears self-evident that the government’s asserted interest — the amelioration of secondary effects associated with late night operation of sexually-oriented businesses, including prostitution, drug use and littering — would be achieved less effectively in the absence of the statute. Fair Public Policy argues that the Arizona legislators did not consider any evidence particular to late night hours, but this assertion is belied by the record. Testimonial evidence was introduced specific to the late night operation of such businesses, and the legislature was briefed on two studies specific to problems associated with nighttime operation of sexually oriented businesses. See National Amusements, Inc., 43 F.3d at 744 (“It is within a government’s purview to conclude that such secondary effects as late-night noise and traffic are likely to adhere to all [adult] entertainment.”).

Nor does the fact that the statute does not permit such establishments to operate prior to noon on Sundays render it overly-broad. The Eleventh Circuit considered and rejected precisely the same argument in Lady J. Lingerie:

176 F.3d at 1365 (quoting Ward, 491 U.S. at 800 , 109 S.Ct. 2746 ).

Furthermore, all six circuits to have considered hours of operation restrictions such as the one at issue here were confronted with regulations containing special provisions for Sunday closing. Indeed, four circuits have upheld regulations that prohibit Sunday hours altogether. See Ben Rich Trading, 126 F.3d at 158; Schultz, 228 F.3d at 837; Star Satellite, 779 F.2d at 1079 ; Richland Bookmart, Inc., 137 F.3d at 438 . Two other circuits have upheld regulations prohibiting sexually-oriented businesses from operating before noon on Sunday, as here. See Mitchell, 10 F.3d at 128 ; Lady J. Lingerie, 176 F.3d at 1365 . In short, because Arizona’s interest in ameliorating secondary effects “would be achieved less effectively absent the regulation,” Colacurcio, 163 F.3d at 553 (quotation omitted), it satisfies the narrow tailoring requirement.

*1170 c

Finally, the statute must “leave open ample alternative channels for communication.” Ward, 491 U.S. at 791 , 109 S.Ct. 2746 . “The Supreme Court generally will not strike down a governmental action for failure to leave open ample alternative channels of communication unless the government enactment will foreclose an entire medium of public expression across the landscape of a particular community or setting.” Colacurcio, 163 F.3d at 554 .

The statute permits the businesses that come within its purview to operate seventeen hours per day Monday through Saturday, and thirteen hours on Sunday, a total of approximately 5,980 hours per year. In Mitchell , the Third Circuit found that a similar restriction “allows those who choose to hear, view, or participate pub-lically in sexually explicit expressive activity more than thirty-six hundred hours per year to do so. We think the Constitution requires no more.” 10 F.3d at 139 . We find that the statute leaves open “ample alternative channels for communication.” Ward, 491 U.S. at 791 , 109 S.Ct. 2746 .

As an alternative ground for finding the statute unconstitutional, Fair Public Policy argues that it is unconstitutionally underinclusive. The argument is that the state’s decision to close sexually-oriented businesses during late night hours must be assessed in light of other types of business which the state permits to operate at night. According to Fair Public Policy, the state must demonstrate that greater late night problems are posed by sexually-oriented businesses than by non-regulated businesses, and if it does not, the statute is underinclusive and is therefore subject to strict scrutiny.

Fair Public Policy’s first major problem is that this argument runs straight into the Supreme Court’s decision in Renton . The adult theater plaintiffs in that case argued that the ordinance at issue was underinclu-sive because it failed to regulate other kinds of adult businesses that are just as likely to produce secondary effects similar to those produced by adult theaters. Renton, 475 U.S. at 52 , 106 S.Ct. 925 . The Court rejected this argument, holding that simply because the city “chose first to address the potential problems created by one particular kind of adult business in no way suggests that the city has ‘singled out’ adult theaters for discriminatory treatment.” Id. at 53 , 106 S.Ct. 925 .

Fair Public Policy gamely attempts to distinguish Renton by pointing out that the Court in Renton dealt with a comparison of one kind of adult entertainment business with other kinds of adult entertainment businesses, whereas their argument here is that the state may not single out the entire industry of adult entertainment. As we have previously explained, however, the Supreme Court has consistently stated that so long as the legislature’s motive is the amelioration of secondary effects, sexually-oriented businesses may indeed be singled out. As the Supreme Court in R.A.V. v. City of St. Paul, 505 U.S. 377 , 112 S.Ct. 2538 , 120 L.Ed.2d 305 (1992), explained,

Id. at 387, 389 , 112 S.Ct. 2538 (emphasis in original) (citations and quotations omitted).

The State “may choose to treat adult businesses differently from other businesses .... ” Isbell, G and B Emporia, Inc., 258 F.3d 1108, 1116 (9th Cir.2001); see also Young, 427 U.S. at 70-71 , 96 S.Ct. 2440 (“[T]he State may legitimately use the content of these materials as the basis for placing them in a different classification from other motion pictures.”). If this is true as a general proposition, then it must also be true as to the specific proposition that a state may single out sexually-oriented businesses to regulate their hours of operation. See Ben Rich Trading, Inc., 126 F.3d at 163 (“[A] municipality may regulate hours of adult businesses differently than other businesses without raising a strong inference of discrimination based on content.”).

TV

In short, we reject Fair Public Policy’s argument that we need to assess the regulation in light of how other classes of businesses are treated under Arizona law. 4 The State may choose to treat adult businesses differently from other businesses so long as it does so for the right reasons, and it has done that here. It need do no more.

The judgment of the district court is AFFIRMED.

. We adopt the nomenclature used in the statute for the sake of convenience.

. An "escort agency” is "a person or business association that furnishes, offers to furnish or advertises the furnishing of escorts as one of its primary business purposes for any fee, tip or other consideration.” Ariz.Rev.Stat. § 13-1422(D)(7). An "escort” is "a person who for consideration agrees or offers to act as a companion, guide or date for another person or who agrees or offers to privately model lingerie or to privately perform a striptease for another person.” Id. § 13-1422(D)(6).

. The parties argue at great length over whether or not we may consider the contents of the studies that document the secondary effects associated with sexually-oriented businesses, and that were placed in the district court record during the course of these proceedings. While the Arizona legislature was briefed on these studies, the actual studies themselves were not before the legislature pri- or to § 13-1422’s enactment, and it is therefore so-called post-enactment evidence. *1167 However, in Alameda Books the Supreme Court specifically contemplated that the state could indeed rely on post-enactment evidence in support of its position, but only if the plaintiffs succeed in casting doubt on the state's rationale. See Alameda Books, 535 U.S. at 441 , 122 S.Ct. 1728 (if "the burden shifts back” to the state, then state can "supplement the record with evidence renewing support for a theory that justifies the ordinance” (emphasis added)); see also Mitchell, 10 F.3d at 136 (examining "pre-enactment and post-enactment evidence” in determining whether state met its burden); DiMa Corp., 185 F.3d at 829-30 (holding that "a municipality may make a record for summary judgment or at trial with evidence that it may not have had when it enacted the ordinance”); Ben Rich Trading Inc. v. City of Vineland, 126 F.3d 155, 161 (3d Cir.1997) (discussing city’s burden of production and noting that "a record could be established in the court after legislation is passed and challenged”).

. Though we reject Fair Public Policy’s argument that the statute needs to be assessed in light of how other classes of business are treated, we note in passing that Arizona law does indeed provide for restrictions on the nighttime operation of other classes of business. See, e.g., Ariz.Rev.Stat. § 44-1632 ("A city or town may adopt an ordinance prohibiting the operation of pawnshops from 12:00 a.m. to 6:00 a.m.”); Ariz.Rev.Stat. § 4-244(15) ("It is unlawful .... to sell, dispose of, deliver or give spiritous liquor to a person between the hours of 1:00 a.m. and 6:00 a.m. on weekdays, and 1:00 a.m. and 10:00 a.m. on Sundays.”).
