Opinion by Judge D.W. NELSON; Dissent by Judge FERNANDEZ.
D.W. NELSON, Circuit Judge:
This case involves a challenge under the Americans with Disabilities Act of 1990, 42 U.S.C. §§ 12101, et seq. (West Supp.1999) (“ADA”), and its regulations to California’s $6 biennial fee for disability parking placards. The State of California, Department of Motor Vehicles [hereinafter “California”], appeals the district court’s grant of partial summary judgment in favor of William Robert Dare, Gray Petillo, and the class of plaintiffs they represent. California claims that the fee does not violate the ADA and that a blanket prohibition on such nominal fees is unconstitutional. We disagree and affirm the district court.
Facts and Procedural History
California has a comprehensive priority parking program for qualifying disabled individuals and veterans. See Cal. Veh. Code. §§ 295.5, 295.7 (West 1999). California provides these individuals with extensive priority parking and exemptions [1170]*1170from all parking meter fees and most parking time restrictions. See id. §§ 22511.5, 22511.7, 22511.8. To prevent abuse, California limits access to these privileges to vehicles displaying state-issued disability license plates or parking placards. See id. §§ 22507.8, 22511.5. California imposes significant fines upon illegal use of disability parking spaces and authorizes local entities to establish enforcement units. See id. §§ 4461, 4463(d), 22507.9, 22511.8, 22511.56, 22511.58, 42001.5.
Registered vehicle owners who are disabled themselves or who use their vehicles to transport disabled individuals at least 51% of the time can obtain disability license plates. California charges the standard license plate fees for these special plates. See id. §§ 5007(a), 9250. In lieu of or in addition, to a disability license plate, California issues disability parking placards to disabled individuals for a $6 fee. See id. § 22511.55. Individuals may use these portable placards in multiple vehicles. The placards expire if not renewed every two years, and California charges fees for renewal or replacement. See id. § 22511.55(a)(3) & (c)(2). The placard fees partly defray the cost of the disability parking program.
On August 13, 1996, Dare and Petillo, two disabled individuals, filed a class action lawsuit challenging California’s $6 placard fee as a violation of ADA Title II and its promulgating regulations. Dare and Petillo allege that the fee constitutes an impermissible surcharge upon measures necessary to provide the nondiserim-inatory treatment of individuals and groups required by the ADA. They rely on 42 U.S.C. § 12132, which states that “[sjubject to the provisions of this sub-chapter, no qualified individual shall, by reason of such disability, be excluded from participation in or denied the benefits of the services, programs, or activities of a public entity, or be subjected to discrimination by any such entity.” 42 U.S.C. § 12132. To prove the ADA’s particular prohibition of surcharges on parking permits, Dare and Petillo cite 28 C.F.R. § 35.130(f), promulgated by the Department of Justice in implementing the ADA, which states that
[a] public entity may not place a surcharge on a particular individual with a disability or any group of individuals with disabilities to cover the costs of measures, such as the provision of auxiliary aids or program accessibility, that are required to provide that individual with the nondiscriminatory treatment required by the Act or this part.
28 C.F.R. § 35.130(f) (1998).
The district court granted partial summary judgment with respect to the class of people qualifying as disabled under the ADA,1 found the fee to be an impermissible surcharge, and ordered a permanent injunction against California’s imposition of the fee. California timely appeals.
Jurisdiction
We have jurisdiction pursuant to 28 U.S.C. § 1292(a)(1) (West Supp.1999) to review the district court’s interlocutory order granting a permanent injunction. Because the district court’s partial summary judgment order provides legal authority for the injunction and is thus inextricably bound with it, we also have jurisdiction to review that order. See Paige v. State of California, 102 F.3d 1035, 1040 (9th Cir.1996).
Standard of Review
We review for abuse of discretion the district court’s grant of a motion for a permanent injunction, see Gaudiya Vaishnava Soc. v. City of San Francisco, 952 F.2d 1059, 1062 (9th Cir.1991), but review any determination underlying the grant of the motion by the standard that applies to that determination, see Multnomah Legal Sens. Workers Union v. Multnomah County Legal Aid Serv., 936 F.2d 1547, [1171]*11711552 (9th Cir.1991). We review de novo a district court’s grant of a motion for partial summary judgment. See Thompson v. Holy Family Hosp., 121 F.3d 537, 539 (9th Cir.1997).
Discussion
This case raises two main issues: (1) Does California’s $6 placard fee violate Title II of the ADA and its implementing regulations, and, if so, (2) was Congress’s enactment of Title II of the ADA a valid exercise of its power under § 5 of the Fourteenth Amendment to abrogate California’s Eleventh Amendment immunity from suit? Because we answer both of these questions in the affirmative, we affirm the district court’s grant of partial summary judgment and a permanent injunction against imposition of the placard fee.
I. Violation of ADA Title II
Analyzing whether California’s $6 placard fee violates the ADA requires three inquiries. First, what obligations does Title II impose upon states regarding fees for measures under the ADA? Second, does Public Law 100-641, 23 U.S.C. § 402 (West Supp.1999), which contemplates a fee for disabled parking placards as part of a uniform system for disabled parking, limit states’ Title II obligations? Third, are these obligations violated by California’s $6 fee for parking placards? As explained below, we conclude that the $6 fee constitutes a surcharge for required measures in violation of the ADA and its implementing regulations.
A. Obligation under Title II
In order to evaluate whether a fee constitutes a surcharge that violates Title II of the ADA, we conduct a two-part inquiry. First, as a threshold matter, we consider whether the measure for which California levies the fee is “required to provide that individual or group nondiscriminatory treatment” as mandated by the ADA. 28 C.F.R. § 35.130(f). If California charges for a measure not required under the ADA, the inquiry ends; 28 C.F.R. § 35.130(f) only forbids surcharges for “required” measures.
Second, we evaluate whether the fee for the measure is a surcharge; in other words, we consider whether it constitutes a charge that nondisabled people would not incur. If nondisabled people pay the same fee for an equivalent service, the charge to disabled people would not constitute a surcharge bn a “required” measure. Thus, for example, a state can charge a fee for disabled license plates so long as it charges the same fee for nondisabled license plates.
Because surcharges against disabled people constitute facial discrimination, the meaningful access test formulated by the Supreme Court in Alexander v. Choate, 469 U.S. 287, 105 S.Ct. 712, 83 L.Ed.2d 661 (1985), does not apply. Under this test, a court considers whether the allegedly discriminatory measure prevents “meaningful access to the benefit that the grantee offers.” Id. at 301, 105 S.Ct. 712. The Ninth Circuit has applied this test in the ADA context to evaluating whether facially neutral laws violate § 12132. See Hunsaker v. Contra Costa County, 149 F.3d 1041, 1042—43 (9th Cir.1998); Crowder v. Kitagawa, 81 F.3d 1480, 1484 (9th Cir.1996).
Using this standard in the context of facially discriminatory laws, however, would ignore the clear language of Title II. Cf. Bay Area Addiction Research & Treatment, Inc. v. City of Antioch, 179 F.3d 725, 733-35 (9th Cir.1999) (holding that the reasonable modifications test does not apply to facially discriminatory laws because they present per se § 12132 violations). § 12132 covers not only “exclusion from participation in or [denial of] benefits of the services, programs, or activities of a public entity,” but also being “subjected to discrimination by any such entity.” 42 U.S.C. § 12132. By reviewing all § 12132 claims under a meaningful access test, this Circuit would focus only on exclusions and denials, and ignore completely the discrimination clause, not to mention the explicit [1172]*1172language of the ADA regulation at issue here. Other courts evaluating fees similar to the one at issue here have read the statute and ADA regulation together rather than applying a meaningful access test. See Thompson v. Colorado, 29 F.Supp.2d 1226, 1231 (D.Colo.1998); Thrope v. State of Ohio, 19 F.Supp.2d 816, 824 (S.D.Ohio 1998); McGarry v. Director, Dept. of Revenue, 7 F. Supp.2d 1022, 1028 (W.D.Mo.1998). We thus follow their approach and do the same; we hold that when states apply charges to required measures, we consider whether these fees constitute a surcharge forbidden under the ADA.
B. Effect of Public Law 100-6H
The government urges us to view Public Law 100-641 and the regulations promulgated pursuant to it as justifying the placards surcharge. On November 9, 1988, prior to the passage of the ADA, Congress enacted Public Law 100-641, 23 U.S.C. § 402. This law indicates that the Secretary of Transportation shall issue regulations which: (1) establish a uniform system for handicapped parking designed to enhance the safety of handicapped individuals and (2) encourage adoption of such a system by all the states. See id.
Pursuant to Public Law 100-641, the Department of Transportation (DOT) promulgated regulations in March 1991, eight months after Congress enacted the ADA. The DOT regulations provide in pertinent part that:
Special license plates, removable windshield placards, or temporary removable windshield placards displaying the International Symbol of Access shall be the only recognized means of identifying vehicles permitted to utilize parking spaces reserved for persons with disabilities which limit or impair the ability to walk.
23 C.F.R. § 1235.6 (1998). DOT regulations further provide that each state shall issue special license plates upon the application of a person with a disability that impairs the ability to walk and that “[t]he fee for the issuance of a special license plate shall not exceed the fee charged for a similar license plate for the same class vehicle.” Id. § 1235.3. In contrast to the provisions concerning license plate fees, neither Public Law 100-641 nor the regulations prohibit the imposition of placard fees.
The government’s argument fails, however, because Public Law 100-641 is purely hortatory. See McGarry, 7 F.Supp.2d at 1026. Congress enacted Public Law 100-641 two years before the ADA and the law has no enforcement mechanism. Even California concedes that in recognizing principles of federalism and state sovereignty, Congress rendered state compliance with Public Law 100-641 completely voluntary.
In contrast, the ADA expressly applies to the states through Congress’s Fourteenth Amendment powers, as discussed in more detail in Part II. Regulations promulgated pursuant to the ADA bind states so long as the regulations are not arbitrary, capricious, or contrary to the ADA. See Does 1-5 v. Chandler, 83 F.3d 1150, 1153 (9th Cir.1996). As discussed below, 28 C.F.R. § 35.130(f) meets that standard. We thus evaluate California’s surcharge based on the requirements of Title II and 28 C.F.R. § 35.130(f). Public Law 100-641 does not impact our analysis.
C. Application to the California Fees
Applying this approach to the California fee at issue, we find the fee to be a surcharge for a required measure in violation of the ADA. The ADA requires special parking arrangements such as handicapped parking spaces. These spaces allow disabled people equal access to public buildings in which California provides services, programs, and activities. Because California polices handicapped parking spaces, disabled people need placards or license plates to use them. California thus meets the ADA’s requirement for nondiscriminatory access to public buildings by providing disabled people with placards and license plates.
[1173]*1173Furthermore, California’s provision of license plates alone would not be sufficient to give individuals nondiscriminatory access to public places. In addition to the fact that many disabled people may not own cars or have someone who drives them 51% of the time, even those who do may sometimes have to use other vehicles as passengers or as drivers. They may rent cars or wish to drive with another person. To require disabled people to use only a designated car for which they have a license plate restricts them far more in accessing public places than people who lack their disabilities. This reasoning comports with cases by other courts that have struck down fees like the one in California. See Thompson, 29 F.Supp.2d at 1231-32; Thrope, 19 F.Supp.2d at 825; McGarry, 7 F.Supp.2d at 1028.
Because providing the placards is a required measure under California’s current program of providing access to handicapped parking spaces, we turn to the question of whether charging the fee for them constitutes a forbidden surcharge. This issue hinges on whether California provides the same fee for an equivalent service for nondisabled people. In support of such equivalence, the appellees argue that the placard fee is comparable to, and probably less than, charges nondisabled people accrue at parking meters. California thus claims that if the $6 fee is viewed as a partial payment of waived meter fees, then disabled people are not being charged more than other people.
California’s argument fails, however, because many public places do not have parking meters and people who lack disabilities face no fees in parking at those places. Such a distinction is unacceptable. Charging disabled people for parking that would otherwise be free constitutes discrimination in the provision of access to public buildings, a measure required under the ADA. We thus affirm the district court on this issue and hold that California’s fee for handicapped parking placards violates the ADA.
II. Constitutionality
Having established an ADA violation, we turn to the constitutional issues raised by the government. This Circuit has held that in enacting Title II of the ADA, Congress validly abrogated state sovereign immunity pursuant to its Fourteenth Amendment powers. See Clark v. California, 123 F.3d 1267, 1270-71 (9th Cir.1997). The majority of Circuits addressing this issue have followed this Circuit’s approach in Clark.2,
We continue to adhere to our holding in Clark today. In light of the Supreme [1174]*1174Court’s recent decision in Florida Prepaid Postsecondary Education Expense Board v. College Savings Bank, — U.S. -, 119 S.Ct. 2199, 144 L.Ed.2d 575 (1999) [hereinafter Florida Prepaid], and the circuit split on this issue, however, we provide further discussion of Title II of the ADA as an appropriate Congressional exercise of its § 5 powers that thus accords with both the Tenth and Eleventh Amendments.
A. Eleventh Amendment
1. Title II of the ADA
When Congress both expresses unequivocal intent to abrogate immunity and also acts pursuant to its § 5 powers, a state’s immunity is waived. See Seminole Tribe of Florida v. Florida, 517 U.S. 44, 55, 116 S.Ct. 1114, 134 L.Ed.2d 252 (1996); Clark, 123 F.3d at 1269. As noted in Clark, “Congress has unequivocally expressed its intent to abrogate the State’s immunity under ... the ADA,” 123 F.3d at 1269. The focus of our discussion is therefore on why Title II constitutes a valid exercise of Congress’s powers under § 5 of the Fourteenth Amendment.
The Court’s recent decision in Florida Prepaid clarifies the congruence and proportionality test outlined in City of Boerne v. Flores, 521 U.S. 507, 117 S.Ct. 2157, 138 L.Ed.2d 624 (1997). The first step of this test involves identification of the “Fourteenth Amendment ‘evil’ or ‘wrong’ that Congress intended to remedy,” using historical experience as a reference point. Florida Prepaid, 119 S.Ct. at 2207 (quoting City of Boerne, 521 U.S. at 525, 117 S.Ct. 2157). The second step requires consideration of whether the provisions of the statute are proportional to their remedial or preventive goal. See id. at 2210 (quoting City of Boerne, 521 U.S. at 532, 117 S.Ct. 2157).
Before applying this test to Title II of the ADA, we note that Congress’s enforcement authority is at its apex when fashioning remedies aimed at the core Fourteenth Amendment guarantee of Equal Protection. City of Boeme and Florida Prepaid both emphasized Congress’s power in dealing with discrimination, such as in the voting rights context. See Florida Prepaid, 119 S.Ct. at 2207; City of Boerne, 521 U.S. at 525-27, 117 S.Ct. 2157. The Court explained that “[l]egislation which deters or remedies constitutional violations can fall within the sweep of Congress’ enforcement power even if in the process it prohibits conduct which is not itself unconstitutional and intrudes into legislative sphere of autonomy previously reserved to the States.” Florida Prepaid, 119 S.Ct. at 2206 (quotation omitted); City of Boerne, 521 U.S. at 518, 117 S.Ct. 2157 (internal quotation omitted).
a. Congruence
Although disabled people do not constitute a suspect class, the Equal Protection Clause prohibits irrational and invidious discrimination against them. See City of Cleburne v. Cleburne Living Center, 473 U.S. 432, 439, 446, 105 S.Ct. 3249, 87 L.Ed.2d 313 (1985). When it enacted the ADA, Congress made specific factual findings of arbitrary and invidious discrimination against the disabled. See id. § 12101(a)(7). On the basis of these findings, Congress concluded that the ADA was a necessary legislative response to a long history of arbitrary and irrational discrimination against people with disabilities. See 42 U.S.C. § 12101(b).3 We thus hold that the ADA in general and Title II in particular satisfy the congruence requirement.
[1175]*1175
b. Proportionality
Having established the ADA’s congruence with Congress’s power to enforce the Equal Protection Clause, we turn to proportionality. In so doing, we reiterate the importance of deference to Congress in this analysis.4 The Supreme Court has specifically found protections for people with disabilities to be an area in which Congressional judgment should be given great deference. See Cleburne Living Center, 473 U.S. at 442-43, 105 S.Ct. 3249.5 The ADA is thus an appropriate exercise of § 5 powers if Congress enacted it in response to a widespread problem of unconstitutional discrimination that includes state programs and services and if the ADA’s provisions are proportional to' the scope of that discrimination.6
As noted above, Congress made extensive factual findings regarding the widespread arbitrary and invidious discrimination which disabled people face. See 42 U.S.C. § 12101(a). The ADA’s particular provisions for each sector then indicate specifically the discrimination which is forbidden and the conduct needed to remedy the discrimination. See 42 U.S.C. § 12101 et seq. Although Title II’s provisions may prohibit some State conduct which would pass muster under rational basis review, the Title’s focus is on eliminating the discrimination outlined in the factual findings.
We thus agree with the Second Circuit and hold that “[i]n light of Congress’s findings of the extent of discrimination against people with disabilities and with due regard to the deference owed to Congress in making such judgments, we will not second-guess Congress’s judgment that the ADA was targeted to remedy and prevent irrational discrimination against people with disabilities.” Muller, 187 F.3d at 309. Congress’s findings were sufficiently extensive and related to the ADA’s provisions that the provisions can “be understood as responsive to or designed to prevent, unconstitutional behavior.” Florida Prepaid, 119 S.Ct. at 2210 (quoting City of Boerne, 521 U.S. at 532). Therefore, we hold that the ADA was a congruent and proportional exercise of Congress’s enforcement powers under § 5 of the Fourteenth Amendment that abrogated Eleventh Amendment immunity.
2. Acceptability of 28 C.F.R. § 85.130(f)
Although California acknowledges the constitutionality of Title II of the ADA, it claims that the prohibition in 28 C.F.R. § 35.130(f) against states charging even de minimis administrative fees violates the Fourteenth Amendment. We disagree.
The primary flaw in the government’s approach is that it conducts its Fourteenth Amendment analysis in a [1176]*1176piecemeal manner. Because the statutory scheme as a whole constitutes a proper exercise of Congress’ power to legislate under § 5, see Clark, 123 F.3d at 1270-71, regulations promulgated pursuant to the ADA “must be given ‘legislative and hence controlling weight unless they are arbitrary, capricious, or clearly contrary to the statute.’ ” Does 1-5, 83 F.3d at 1153 (quoting United States v. Morton, 467 U.S. 822, 834, 104 S.Ct. 2769, 81 L.Ed.2d 680 (1984)).7
Here, the regulation is not arbitrary, capricious, or contrary to the ADA. See id. Title II protects the rights of disabled people to have the same public services, programs, and activities as those who are not disabled. See 42 U.S.C. § 12132. If public entities place a surcharge on measures that help disabled people achieve this parity, disabled people then are paying fees others do not and so are not being treated equally.
Forbidding such additional charges is a solution aimed at preventing this type of discrimination; it addresses the improper approach to funding services for the disabled, see 28 C.F.R. § 35.130(f), while leaving states broad flexibility, to administer and fund their programs otherwise, cf. Duprey v. State of Conn., Dept. of Motor Vehicles, 28 F.Supp.2d 702, 708 (D.Conn.1998) (“If the DMV wants to pass on the costs of providing placards, rather than absorbing the costs itself, it must pass the cost on to all parkers, and not just those disabled individuals protected by the ADA.”). The rationale for this regulation thus dovetails neatly with the purposes of Title II. We therefore hold that 28 C.F.R. § 35.130(f) has controlling weight.
B. Tenth Amendment
Because Title II falls within Congress’s Fourteenth Amendment powers, it does not conflict with powers reserved to the states under the Tenth Amendment. See Ex parte Virginia, 100 U.S. 339, 344-47, 25 L.Ed. 676 (1879); see also Armstrong, 124 F.3d at 1024-25. We thus hold that the ADA does not violate the Tenth Amendment.
Conclusion
The California placard fee violates the ADA and its implementing regulations. Because the ADA constitutes an appropriate exercise of Congress’s enforcement powers under § 5 of the Fourteenth Amendment, California’s Tenth and Eleventh Amendment challenges fail. Furthermore, we accord 28 C.F.R. § 35.130(f) controlling weight as an regulation promulgated pursuant to the ADA that is not arbitrary, capricious, or contrary to the statute. We therefore AFFIRM the district court’s grant of summary judgment in favor of appellees and of a permanent injunction against imposition of the surcharge.
AFFIRMED.
