OPINION OF THE COURT
Marylin G. Diamond, J.
The issue raised by these three related actions is whether the City of New York in its attempt to disperse the present concentration of x-rated businesses in certain areas of the City has violated plaintiffs’ rights of freedom of expression guaranteed under the New York State Constitution.
Plaintiff in Stringfellow’s of N. Y. v City of New York (Stringfellow’s) is an adult entertainment establishment that features topless female dancers. Plaintiffs in Hickerson v City of New York (Hickerson) are Manhattan and Bronx residents who allege they regularly patronize adult entertainment establishments located throughout the City of New York. Plaintiffs in Amsterdam Video v City of New York (Amsterdam Video) are approximately 92 owners and operators of adult establishments. Plaintiffs, in these actions consolidated for the disposition of the underlying motions for summary judgment, seek to have this court declare unconstitutional the text amendment N 950384 ZRY to the Zoning Resolution of the City of New York (the Amended Zoning Resolution) on the ground that it unconstitutionally violates their freedom of expression guaranteed under this State’s Constitution (NY Const, art I, §8).
Prior Proceedings
The Amsterdam Video and Hickerson actions were removed from State court to the United States District Court for the [379] Southern District of New York. The District Court then remanded that portion of the claims arising under the New York State Constitution, holding in abeyance the claims in both actions predicated on the Federal Constitution. The String fellow’s action was commenced in State court.
Upon remand, this court granted Times Square Business Improvement District (TSBID) and the American Alliance for Rights and Responsibilities (AARR) motion to intervene as permissive intervenors. The Appellate Division, First Department, denied Amsterdam Video’s, Hickerson’s and Stringfellow’s motions for a stay and an expedited appeal of that decision.
Background
As of 1965, nine adult entertainment establishments existed in the City of New York. By 1976, the number of such establishments increased to 151. Between 1976 and 1984, the number of adult entertainment establishments declined 13%, from 151 to 131 city wide. In Midtown Manhattan alone, the number of adult uses declined by 48, from 97 to 49. The over-all decline was offset by an increase of 28 adult establishments, from 30 to 58 establishments, in the City’s other four boroughs. Between 1984 and 1993, there was a 35% increase to 177; 107 in Manhattan, 44 in Queens, 15 in Brooklyn, 8 in the Bronx, and 3 in Staten Island.
In response to community concerns regarding the increase in adult establishments and their allegedly adverse impacts upon those communities, the New York City Department of City Planning (DCP) undertook a study in late 1993 (the DCP Study) to determine the nature and extent of the impact that adult establishments have on communities and to assist the New York City Planning Commission (the Planning Commission) in determining whether to amend the City’s Zoning Resolution so as to specifically regulate adult entertainment establishments.
As part of its study, DCP selected seven areas where adult uses are located: Manhattan Community Districts 4, 5, and 7; Bronx Community District 5; Brooklyn Community District 7; Queens Community District 2; and Staten Island Community District 2. DCP did not study the Times Square area because that area was already under study by TSBID (the TSBID Study). DCP also surveyed representatives from community boards, local organizations and businesses, the adult entertainment industry, as well as real estate brokers, and police and [380] sanitation officers in order to compile information concerning the impact of adult entertainment establishments on land use, street conditions, property values, and crime. In addition, the DCP Study considered local studies and surveys such as the Chelsea Business Survey and the TSBID Study. The DCP Study also included a survey and review of adult entertainment studies conducted by other cities such as Islip, New York; Los Angeles, California; Indianapolis, Indiana; Whittier, California; Austin, Texas; Phoenix, Arizona; Manatee County, Florida; New Hanover County, North Carolina; and the State of Minnesota. Also considered were the impacts identified by the City Planning Commission’s 1977 Report, the 1983 Annual Report of the Mayor’s Office of Midtown Enforcement, and the 1993 Task Force on the Regulation of Sex-Related Businesses.
The DCP Study concluded that the number of adult uses citywide has increased substantially in recent years, that a majority of the adult entertainment establishments are located in zoning districts that permit residential developments, and that such establishments as they proliferate tend to concentrate in certain neighborhoods. For example, in Manhattan, adult establishments have clustered in central locations such as Times Square. In the outer boroughs, these establishments have concentrated along major arteries, such as Queens Boulevard in Queens and Third Avenue in Brooklyn. The DCP concluded that the presence of adult entertainment establishments, particularly those that are concentrated in a specific area, tends to produce negative secondary effects such as increased crime, decreased property values, and reduced shopping and commercial activities. Accordingly, the DCP recommended to the Planning Commission that the Zoning Resolution be amended so as to regulate adult entertainment establishments more closely than other commercial uses by placing restrictions on the proximity of adult uses to residential areas, schools, houses of worship, and other adult establishments. Prior to this recommendation, the City’s Zoning Resolution had made no distinction between adult entertainment establishments and other commercial activities.
Pending enactment of amendments to the Zoning Resolution, the Planning Commission approved and the New York City Council adopted an interim amendment to the Zoning Resolution which imposed a one-year moratorium on new or expanded adult entertainment establishments. During the moratorium, no new adult entertainment establishments were allowed and no existing establishment could be enlarged or extended for a [381] period of one year from its effective date of November 24,1994. The moratorium applied to stores featuring adult books, magazines, videotapes, topless or nude bars and adult theaters featuring films, videotapes, or live sex shows.
On March 21, 1995, the DCP and the New York City Council Land Use Committee filed a joint application to amend the Zoning Resolution by proposing permanent regulations that would place restrictions on the location, size and signage of specified types of adult establishments. The objective of the proposed amendments to the Zoning Resolution would be to break the concentration of adult entertainment establishments in certain neighborhoods by dispersing such businesses to certain permissible zoned districts. Following extended public hearings, comments and recommendations on the proposed regulations, the City Council approved the Amended Zoning Resolution on October 25, 1995, effective on that date.
The Amended Zoning Resolution
The centerpiece of the Amended Zoning Resolution is a set of locational restrictions and anticoncentration provisions that are designed to shield the City’s residential neighborhoods, and the facilities and commercial areas that serve them, from the negative impacts produced by adult uses. Even before the regulations were adopted, the general regulatory scheme embodied in the Zoning Resolution prohibited new commercial development in the City’s residentially zoned districts. Under the Amended Zoning Resolution, adult uses are also barred from certain districts that are zoned for commercial and manufacturing uses, but, in addition, permit new residential development (Amended Zoning Resolution § 32-01 [a]; § 42-01 [a]). Many of these districts are mapped within residential districts and contain the local retail strips that serve the everyday commercial needs of the surrounding residential neighborhoods. Adult uses continue to be allowed, subject to certain restrictions, in a number of commercial and manufacturing districts that are mapped throughout the City and in which a variety of retail, entertainment and other commercial uses are permissible (Amended Zoning Resolution § 32-01 [b]; § 42-01 [b]).
In the districts in which adult establishments are permitted, certain restrictions are imposed to further ensure that such uses do not adversely impact residential communities or the facilities that serve them. In these districts, adult establishments must be located at least 500 feet from any school, day [382] care center, or house of worship and at least 500 feet from most zoning districts in which new residential uses are allowed (Amended Zoning Resolution § 32-01 [a]; § 42-01 [b]).
The Amended Zoning Resolution also contains several provisions designed to prevent the concentration of adult uses. In the districts in which adult entertainment are permitted, a new adult use must be located at least 500 feet from any other adult use (Amended Zoning Resolution § 32-01 [c]; § 42-01 [c]). Moreover, only one adult establishment, not to exceed 10,000 square feet of usable floor area, may be located on a zoning lot (Amended Zoning Resolution § 32-01 [d], [e]; § 42-01 [d], [e]). The Amended Zoning Resolution also regulates the size, placement and illumination of accessory business signs on adult establishments, but not their content (Amended Zoning Resolution §§ 32-69, 42-55).
The Amended Zoning Resolution subjects existing adult establishments that do not conform to the restrictions contained therein to the amortization provisions which require them to come into conformity or terminate within one year of the amendment’s effective date of October 25, 1995 (Amended Zoning Resolution §§ 52-734, 52-77). The Amended Zoning Resolution further provides that upon application of the owner of a nonconforming adult establishment the Board of Standards and Appeals may allow a nonconforming establishment to be maintained for more than one year from the effective date of the regulations. In order to grant such an extension, the Board must find that the applicant has made substantial expenditures related to the nonconformity, which the applicant has been unable to recover by the prescribed one-year deadline, and that the extension is the minimum necessary to enable the applicant to recover those expenditures (Amended Zoning Resolution § 72-40).
The Amended Zoning Resolution provides for a limited exemption for adult establishments existing as of October 25, 1995 (Amended Zoning Resolution § 32-01 [f]; § 42-01 M). These establishments that are not located in the prohibited districts and are otherwise conforming except that they are within 500 feet of another adult use, located on the same zoning lot of another adult use, or exceed 10,000 square feet of usable floor area, would not be subject to the amortization provisions of section 52-77.
Discussion
Analysis begins with a review of two separate and competing principles implicated in these actions: freedom of expression [383] and governmental zoning powers. Article I, § 8 of the New York State Constitution provides in relevant part: "Every citizen may freely speak, write and publish his sentiments on all subjects, being responsible for the abuse of that right; and no law shall be passed to restrain or abridge the liberty of speech or of the press.” This State’s highest Court has ruled that New York’s constitutional guarantee of freedom of expression affords greater protection than its Federal counterpart (People ex rel. Arcara v Cloud Books, 68 NY2d 553, 557 [1986]). In so ruling, the Court of Appeals emphasized that "New York has a long history and tradition of fostering freedom of expression, often tolerating and supporting works which in other States would be found offensive to the community” (supra).
With regard to zoning, the Court of Appeals has recognized that municipalities have broad powers to implement land use controls to meet the increasing encroachments of urbanization on the quality of life (Matter of Town of Islip v Caviglia, 73 NY2d 544, 550 [1989]; Asian Ams. for Equality v Koch, 72 NY2d 121, 128-129 [1988]; Matter of Harbison v City of Buffalo, 4 NY2d 553, 559 [1958]). Restrictions on real property use and development are justified as a proper exercise of a municipality’s police power to advance the public health, safety and welfare (Matter of Town of Islip v Caviglia, 73 NY2d, supra, at 550, citing Berman v Parker, 348 US 26, 32 [1954], and Udell v Haas, 21 NY2d 463, 469-470 [1968]).
Preventing neighborhood deterioration is undeniably a legitimate public objective. (See, Berman v Parker, 348 US, supra, at 32-33.) Without stable residential and commercial neighborhoods large sections of a modern city can quickly deteriorate into an urban jungle with tragic consequences to social, environmental and economic values (Young v American Mini Theatres, 427 US 50, 80 [1976] [Powell, J., concurring]). Zoning when used to preserve the character of specific areas of a city is " 'the most essential function performed by local government, for it is one of the primary means by which we protect that sometimes difficult to define concept of quality of life.’ ” (Supra.)
Zoning ordinances are legislative acts that enjoy a strong presumption of constitutionality and if there is a reasonable relation between the end sought to be achieved and the means adopted to achieve that end the regulation will be upheld (Matter of Town of Islip v Caviglia, 73 NY2d, supra, at 550-551, citing Asian Ams. for Equality v Koch, 72 NY2d, supra, at 132; McMinn v Town of Oyster Bay, 66 NY2d 544, 549 [1985], and [384] Shepard v Village of Skaneateles, 300 NY 115, 118 [1949]). Where the issue is "fairly debatable” courts must defer to the legislative judgment on the need for such regulation (Matter of Town of Islip v Caviglia, 73 NY2d, supra, at 551).
An unavoidable constitutional tension is created, however, when a municipality’s zoning power is used to regulate lawfully operating establishments that are devoted to adult uses protected under this State’s constitutional guarantee of freedom of expression (see, Matter of Town of Islip v Caviglia, 73 NY2d, supra, at 551). It is against this framework that this court must determine whether the Amended Zoning Resolution violates plaintiffs’ freedom of expression.
The parties agree that the Court of Appeals decision in Islip (supra) is dispositive of the constitutional issues raised herein. They differ on its application to the instant case. In Islip, the Town of Islip sought to enjoin the continued operation of an adult bookstore in a restricted zone on the grounds that its operation was in violation of the Town’s restrictive zoning ordinance applicable to adult uses. On appeal to the Court of Appeals, the restrictive zoning ordinance was found to be content-neutral because it was enacted to prevent the deterioration of neighborhoods, and, as such, was upheld as a valid exercise of governmental police power.
The test as articulated by the Islip Court to determine whether a zoning ordinance, such as the Amended Zoning Resolution, is constitutional under the State’s Constitution is as follows: (1) the ordinance must be justified by concerns unrelated to speech; and (2) it must be "no broader than necessary” to achieve its purpose (Matter of Town of Islip v Caviglia, 73 NY2d, supra, at 558-559, citing People ex rel. Arcara v Cloud Books, 68 NY2d 553, supra). Although the first prong of this two-prong test is not labeled as such, it is essentially the same type of inquiry as the "predominant purpose / secondary effects” test enunciated by the United States Supreme Court in Renton v Playtime Theatres (475 US 41 [1986]) in analyzing restrictive zoning regulations in the context of the First Amendment (Matter of Town of Islip v Caviglia, 73 NY2d, supra, at 551, 557-558). In his dissent, Associate Judge Titone observed, without comment from the majority, that the majority’s "reliance on the purpose of Islip’s ordinance is remarkably similar to the 'predominant purpose’ test espoused in Renton v Playtime Theatres”, and reasoned that "[although the majority does not explicitly adopt or apply the 'predominant purpose’ test, in the absence of some other clearly articulated principle, [385] the majority opinion must be read as an incorporation of the 'predominant purpose’ test into the framework of our State’s freedom of speech jurisprudence” (Matter of Town of Islip v Caviglia, 73 NY2d, supra, at 570 [Titone, J., dissenting]). The Islip Court also recognized that Renton requires as another component of the two-prong test that a restrictive zoning ordinance, such as the Amended Zoning Resolution, provide alternative locations for adult use businesses (Matter of Town of Islip v Caviglia, 73 NY2d, supra, at 554-555).
In challenging the constitutionality of the Amended Zoning Resolution, plaintiffs contend that since its language bans the distribution or exhibition of nonobscene adult entertainment, a form of protected speech, in designated areas of the City, it is a content-based regulation that purposefully regulates speech. As such, plaintiffs contend that the Amended Zoning Resolution is presumptively invalid. The City, TSBID and AARR argue that the Amended Zoning Resolution is not content-based, but content-neutral under Islip (supra) and Renton (supra).
Whether the Amended Zoning Resolution is content-based or content-neutral is of no import. The compelling State interest analysis applicable to content-based regulations involves the same inquiry needed in determining whether the Amended Zoning Resolution is content-neutral; that is whether it was justified by concerns based on adverse secondary effects, rather than speech. In fact, in analyzing Islip’s zoning ordinance as a content-based regulation, Associate Judge Titone noted in his dissent, without comment from the majority, that "[w]hile there can be no doubt that a municipality has an interest in 'the stability and revitalization of the neighborhoods’ * * * this interest cannot be considered 'compelling’ without at least some showing that the form of expression to be regulated has an actual and specific deleterious effect on the community” (Matter of Town of Islip v Caviglia, 73 NY2d, supra, at 567). The critical question then becomes whether the enactment of the Amended Zoning Resolution was a purposeful attempt to regulate speech or an attempt to address the alleged adverse secondary effects caused by the proliferation of adult establishments.
Plaintiffs contend that the Amended Zoning Resolution is constitutionally infirm because the City has failed to demonstrate the existence of adverse secondary effects. They criticize the City’s reliance on other studies conducted nationwide and locally. Specifically, they argue that the DCP Study and other [386] studies on adverse secondary effects considered by the Planning Commission and the testimonial evidence during the public hearings held before the City Council are unreliable since they were not based on empirical or documented data, but rather anecdotal and inconclusive evidence. The Amsterdam Video and Hickerson plaintiffs point to the report prepared by their expert, R. Bruce McLaughlin (McLaughlin), a land-use planning and local government consultant based in Florida, for support. McLaughlin concludes, even though he did not perform his own independent study, that he does not believe that any existing study has demonstrated that adverse secondary effects have resulted from the presence of adult establishments. He also disagrees with zoning studies used in Indianapolis, Los Angeles, Phoenix and Austin among others. Most telling is his attack upon the Islip Study, about which he says: "In my professional opinion, based on the reviews and analyses described above, and on my professional training and experience, there is nothing in the Islip Study that documents the alleged adverse secondary effects of Adult Uses in general, supports the 'legislative findings’ of the Ordinance, or provides information upon which a reasonable and prudent planner or local government official could reasonably believe or rely upon in the regulation of adult entertainment establishments.” (McLaughlin affidavit ^ 171.) This is the very same study which the New York Court of Appeals characterized as follows: "The ordinance was prepared after thorough study of the community by professional planners and municipal officials. The Report on which it was based recognized the competing concerns in its first paragraph when it stated that: 'This report studies the effects of adult entertainment or sex businesses on surrounding uses, both residential and commercial. * * * Materials or entertainment opportunities offered at these businesses are not a concern of this report.’ The research and data underlying the Report supported its conclusion that the presence of such uses had a deleterious effect on the quality of life in the communities of the Town and the ordinance which followed was adopted in conjunction with a comprehensive plan for the development of the Town as a whole” (Matter of Town of Islip v Caviglia, 73 NY2d, supra, at 552).
In Renton (supra), the United States Supreme Court held that a municipality is entitled to rely on the experiences of other cities concerning adverse secondary impacts in enacting a zoning ordinance regulating adult use businesses (Renton v Playtime Theatres, 475 US, supra, at 51). The Supreme Court [387] further held that: "[t]he First Amendment does not require a city, before enacting such an ordinance, 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” (supra, at 51-52 [emphasis added]). In recognizing the legitimacy of this analysis, our Court of Appeals observed that "planning studies, by their nature, are not scientific nor their predictions certain but [a municipality is] entitled to credit the evidence in its study of past deterioration and the prediction that, unless remedied, the deterioration would continue; it [is] not required to wait before acting until its business areas [become] wastelands” (Matter of Town of Islip v Caviglia, 73 NY2d, supra, at 553-554). The Court of Appeals also recognized that "planning studies have established that adult bookstores and other adult entertainment facilities are generally injurious to the maintenance and development of healthy commercial and residential areas” (supra at 551). Thus, the City’s methodology in determining whether adult establishments existing in the City produced negative impacts was constitutionally permissible. Nor was the City, as plaintiffs, particularly Stringfellow’s (supra), contend, required by Islip or Renton to conduct an independent assessment of every adult establishment to determine whether these particular places caused any adverse secondary impacts. All that is constitutionally required is that there is a reasonable belief that adult entertainment businesses, including the upscale kind allegedly offered by Stringfellow’s, produce at least some of the unwanted secondary effects so as to permit the City to experiment with solutions to admittedly serious problems (ILQ Invs. v City of Rochester, 25 F3d 1413, 1418 [8th Cir 1994], cert denied 513 US 1017, citing and quoting Young v American Mini Theatres, 427 US 50, supra).
Based on the foregoing, the City was permitted to rely on the DCP Study, as well as other studies, to determine whether adult use businesses produce adverse secondary effects.
The DCP Study was undertaken in response to growing concerns that adult establishments were proliferating in New York City and concentrating in areas where such establishments had previously not located, causing negative effects on surrounding communities. DCP also considered the study prepared by the TSBID concerning the location and concentration of adult use businesses in the Times Square area which concluded that some adult establishments could exist in the [388] Times Square area, but their growing number and their concentration on Eighth Avenue constitute a threat to commercial prosperity and residential stability.
Also considered was the Chelsea Business Survey which showed that a large majority of the commercial tenants in the area reported a negative impact on the economic vitality of their businesses stemming from the proximity of adult use businesses. An even larger percentage of those surveyed held the belief that the concentration of adult establishments has resulted in a declining potential for doing business in Chelsea. The DCP also considered studies prepared by other States. Those studies essentially concluded that adult entertainment establishments have negative secondary impacts such as increased crime rates, depreciation of property values and deterioration of community character and the over-all quality of urban life. Although there was testimony in opposition to the amendments to the zoning resolution, the great preponderance of such opposition was that the proposals were not restrictive enough and that adult uses should be prohibited in more areas of the City.
The voluminous and comprehensive administrative record clearly demonstrates the City not only reviewed studies from other jurisdictions, but actually used those studies to guide it in its study to determine the existence of negative secondary effects associated with adult use businesses, and in formulating a proper response to combat such effects. Based on this record the City Council was justified in finding that the present configuration of adult use establishments causes adverse secondary effects, a finding which demonstrates that the Amended Zoning Resolution was based on a compelling State interest related to combating such negative effects, rather than restricting speech. As such, the finding is entitled to deference by this court (Matter of Town of Islip v Caviglia, 73 NY2d, supra, at 550-551). It is noteworthy that there are similar characteristics in the City’s Amended Zoning Resolution with other cities’ zoning ordinances regulating adult uses, and significantly that some of those ordinances are more restrictive than the Amended Zoning Resolution (see, e.g., Detroit, Michigan [1,000-foot buffer zone]; Islip, New York [permissible in industrial zone only]; Renton, Washington [1,000-foot buffer zone]; Seattle, Washington [confined to commercial areas]).
Plaintiffs contend that the Amended Zoning Resolution is broader than necessary, and, as such, is unconstitutional. This contention is unavailing. The Islip Court has held that a [389] municipality may utilize its zoning powers to address the negative effects associated with adult use businesses given the fact that such effects are not subject to direct attack (Matter of Town of Islip v Caviglia, 73 NY2d, supra, at 559). The Court deemed this approach as the "most appropriate” response to addressing the existing problems. Under these circumstances, the Amended Zoning Resolution is no broader than necessary, and does not violate the State Constitution.
