OPINION OF THE COURT
The Zoning Hearing Board (“ZHB”) of Easttown Township (“Township”) appeals the District Court’s order directing it to allow Omnipoint Communications Enterprises, L.P. (“Omnipoint”) to erect a telecommunications tower at a designated site within the Township. The ZHB contends that the District Court erred in finding that the ZHB’s decision denying Omni-point’s application was not supported by substantial evidence as required by the Telecommunications Act of 1996 (“TCA”), 47 U.S.C. § 332(c)(7)(B)(iii). Omnipoint argues thаt the District Court was correct on that score and cross-appeals the District Court’s decision denying it damages and attorneys’ fees under the Civil Rights Act, 42 U.S.C. § 1983. We conclude that the District Court erred in its analysis of the relevant state law. Accordingly, we will reverse its order and remand for proceedings consistent with this opinion.
I.
Omnipoint, a wireless Personal Communications Service (“PCS”) provider, entered into a lease with the Or Shalom Synagоgue (“Synagogue”), located in East-town Township, to erect and operate a communications tower on a portion of its property. The proposed white fibreglass tower was to be approximately 110 feet tall, with a diameter of 24 inches at its base and tapering to 16 inches at the top. Omnipoint planned to enclose the base of the tower in a 30-foot by 30-foot structure and surround it with an eight-foot tall chain-link fence topped with barbed wire. To reduce the aesthetic impact of the tower, Omnipoint suggested using it as a flagpole, though it conceded that the tower would be taller and wider than a normal flagpole.
*104 Because the Synagogue property was located in a district zoned AA-residential and the Township’s zoning ordinance imposed a height limitation of 35 feet in such areas, Omnipoint submitted an appliсation to the ZHB for a use variance in order to erect its tower. See 53 P.S. § 10910.2. In the alternative, Omnipoint also submitted a challenge to the validity of the ordinance under the Pennsylvania Constitution and the TCA. See 53 P.S. § 10916.1. Omni-point alleged that the ordinance was invalid under the Pennsylvania Constitution because it excluded wireless facilities and under the TCA because it had the effect of prohibiting wireless service.
The ZHB held public hearings on three separate dates over the course of several months to discuss Omnipoint’s application. At these hearings, Omnipoint contended that the tower was necessary to fill a “gap” in its service in the southern portion of the Township and offered the testimony of several expert witnesses in support of its application. The Township, on the other hand, called only one witness, its Manager, who testified that the challenged ordinаnce was not exclusionary because it had been interpreted to permit special exceptions for cellular facilities in certain areas of the Township, such as the B-business districts. 1 Numerous Township residents also attended the hearings and expressed their opposition to the siting of the tower, largely on the basis that it would be an eyesore in the residential community in which it was to be situated.
At the conclusion of the hearings, the ZHB denied Omnipoint’s application, stating its decision orally at one of its meetings and issuing a 10 page statement of findings and conclusions on a later date. With regard to the use variance request, the ZHB found that local zoning law places a high burden on the applicant to demonstrate why a variance is necessary and that Omnipoint had failed to do so. 2 With regard to the validity challenge under state law, the ZHB fоund that the ordinance had been interpreted “to allow cellular/PCS facilities in certain appropriate zoning districts” within the Township and that, in fact, there were “several cellular or PCS towers or sites operating within the Township borders” and in contiguous areas (A.30-31). As a result, the ordinance could not be said to be exclusionary. The ZHB also observed that the Township’s justification for the challenged ordinance-namely, “preservation of the residential nature of the AA residential districts”falls “within the traditional purposes of zoning regulation, and enforcement of zoning regulations is not negated by the Telecommunications Act of 1996 or [by Pennsylvania law]” (A.26, 30). Finally, the ZHB rejected the challenge under the TCA, concluding that the ordinance did not effectively prohibit wireless service.
In the District Court, Omnipoint did not challenge the ZHB’s conclusion that it had failed to justify a use variance. 3 It did, *105 however, continue to argue that the ordinance was unconstitutional because it was exclusionary. Omnipoint further insisted that the ZHB’s decision upholding the validity of the zoning ordinance was violative of the TCA because it was not supported by substantial evidence, 47 U.S.C. § 332(c)(7)(B)(iii), and because it had the effect of prohibiting wireless service. 47 U.S.C. § 332(c)(7)(B)(i)(II). Finally, Om-nipoint sought damages and attorneys’ fees under the Civil Rights Act, 42 U.S.C. § 1983.
The District Court grаnted summary judgment in favor of Omnipoint and ordered the ZHB to grant Omnipoint’s application. It found that the ZHB’s decision was “based solely on the negative aesthetic impact of the tower” and “did not make any findings that the tower would affect the health, safety, or general welfare of the Township in any manner other than that of aesthetics.”
Omnipoint Communications Enterprises, L.P. v. Zoning Hearing Board of Easttown Township,
Having found the ordinance unconstitutional on this ground, the District Court deemed it unnеcessary to address whether Omnipoint had shown the ordinance to be impermissibly exclusionary under Pennsylvania law or whether the ZHB’s decision was in violation of subsection 332(c)(7)(B)(i)(II) of the TCA because it had the effect of prohibiting wireless services.
See id.
at 516-17. With regard to Omnipoint’s civil rights claims based on the TCA violation, the Court found that the TCA’s remedial scheme is “sufficiently comprehensive to infer Congressional intent to foreclose a § 1983 remedy.”

No. 98-5171,
II.
Subsection 332(c)(7)(B)(iii) of the TCA requires that “[a]ny decision by a State or local government or instrumentality thereof to deny a request to place,
*106
construct, оr modify personal wireless service facilities shall be in writing and supported by substantial evidence contained in a written record.” Substantial evidence is a legal term of art. It “does not mean a large or considerable amount of evidence, ‘but rather such evidence as a reasonable mind might accept as adequate to support a conclusion.’ ”
Pierce v. Underwood,
The District Court in this case correctly observed that “[s'Jection 382(c) (7) (B) (iii) is not intended to supplant the substantive standards to be applied under state or local law.”
Easttown,
Thus, as we pointed out in Penn Township:
[i]t ... seems apparent that subsection 332(c)(7) (B) (iii) is intended to provide procedural protections with respect to the determination of factual issues made by a state or local authority in the course of applying state and local zoning law.... By contrast, it also seems apparent that subsection 332(c)(7)(B)(iii) is not intended to apply to decisions that are not to be made solely on the basis of the factual record before the agency and that are not to be the subject of deferential substantial evidence review.
A decision on the “exclusivity” of a zoning ordinance under the Pennsylvania Constitution is a legal issue that is not subject to deferential judicial' review. See Borough of Edgewood v. Lamanti’s Pizzeria,124 Pa.Cmwlth. 325 ,556 A.2d 22 (1989). While such decisions may involve some consideration of legislative facts, the evidencе to be considered is not limited to the facts of the particular applicant’s case and is not necessarily limited to the record compiled by the local authority.
Id. at 474-75.
As we have noted, Omnipoint did rely on state law before the ZHB. It insisted that the ordinance barring it from erecting its tower was invalid under the Pennsylvania Constitution because it excluded wireless service towers. The law applicable to this kind of claim is well settled. Zoning ordinances in Pennsylvania enjoy a presumption of constitutionality and validity, and the party challenging one bears the “heavy burden” of proving otherwise. See
Penn Township,
In order to overcome this presumption of constitutionality, the challenger must demonstrate that “the ordinance totally excludes an otherwise legitimate use.”
Farrell v. Worcester Township Board of Supervisors,
De jure exclusion exists where an ordinance, on its face, totally bans a legitimate use. De facto exclusion exists where an ordinance permits a use on its face, but when applied acts to prohibit the use throughout the municipality.
Penn Township,
If the challenger is able to establish that the ordinance excludes the use in question, the burden then shifts to the state or locality “to demonstrate that the zoning оrdinance ‘[bjears a substantial relationship to public health, safety, and welfare.’ ”
Id.
(quoting
Borough of Edgewood v. Lamanti’s Pizzeria,
The District Court did not apply these state authorities. As we have noted, it еxpressed no view with regard to the ZHB’s conclusion that Omnipoint had failed to show that the ordinance was exclusionary. Rather, it held that the ordinance restricting the AA-residential district to residential and related uses and to structures no higher than 35 feet was unconstitutional because zoning “based solely on aesthetic reasons [is] not a legitimate exercise of a locality’s power to protect the general welfаre.”
Easttown,
We hold that the District Court’s conclusion is contrary to Pennsylvania law. Residential districts with 35 foot high restrictions are, of course, a common feature of virtually all municipal zoning ordinances.
See
2 Anderson, American Law of Zoning (4th ed. 1996) § 39.55 (“The most common provisions limit buildings in single family residential districts to ... a height not in excess of 35 feet.”). While such reasonable height restrictions have been justified on grounds other than aesthetics,
see id.,
we are confident that the Supreme Court of Pennsylvania would sustain them as a reasonable means of maintaining the residential character of the neighborhood. Pennsylvania courts have repeatedly held that aesthetic considerations promote the general welfare and thus are sufficient to justify the exercise of a locality’s police power to establish zoning
*108
ordinances.
See e.g. Appeal of Girsh,
In arriving at the conclusion that zoning decisions based on aesthetics are not a legitimate exercise of a locality’s police power, the District Court erroneously relied on cases in which Pennsylvania courts have required “extraordinary justification” to overcome a presumptiоn that restrictions on residential lot sizes or other attempts to “establish residential enclaves by excluding population growth” constitute exclusionary zoning and are unduly restrictive of property rights.
Surrick v. Zoning Board of Upper Providence Township,
The District Court also erroneously relied upon our decision in
Pine Gi'ove,
Thе judgment of the District Court thus rests solely on an error of law, and we must reverse.
*109 III.
As we have explained, the District Court found it unnecessary to rule on Omni-point’s claim that the ordinance was imper-missibly exclusionary under Pennsylvania law or its claim that the ordinance had the effect of prohibiting the provision of wireless services in violation of the TCA. Moreover, the record in this case was developed without the benefit of our decision in Penn Township which addressed similar challenges under the Pennsylvania Constitution and the TCA and articulated the legal principles that must control here. Under these circumstances, we deem it prudent to remand this matter to the District Court to give the parties an opportunity to supplement the record and to secure the informed judgment of the District Court.
In Penn Township, as here, a wireless service provider claimed that the challenged ordinanсe was exclusionary because a tower in the area of the township in which towers were permitted would not allow it adequately to fill an alleged gap in its service in another portion of the township. We there held:
Pennsylvania’s rule against exclusionary zoning does not impose upon a township the duty to assure that all providers, regardless of the systems they have chosen to construct, will have a suitable site for а functioning tower -within the township. To be exclusionary, the ordinance must effectively foreclose not only APT’s use, but all use. Yet, APT provided no evidence to the ZHB that other providers could not use any of the 600 acres of M District land to build a tower that would functionally meet their systems’ needs.
Penn Township,
In this case, Omnipoint does not contest the ZHB’s finding that other service providers have existing towers within the Township and in contiguous areas that prоvide service within its borders. While there is some evidence concerning the service of those providers, it is safe to say that the record would be more fully developed had the parties had the benefit of the teachings of Penn Township.
The same is true with respect to the TCA issue. In
Penn Township
we established a two-prong test to determine if the decision of a local zoning authority has “the effect of prohibiting the provision of personal wireless services.” 47 U.S.C. § 332(c)(7)(B)(i)(II). It requires that the serviсe provider first “show that its facility will fill an existing significant gap in the ability of remote users to access the national telephone network.”
Penn Township,
IV.
Omnipoint’s remaining claims are based on the Civil Rights Act. To the extent
*110
Omnipoint claims that the ZHB, acting under color of state law, violated its rights under the TCA, the issues raised need not be addressed until such a violation has been established. However, to the extent Omnipoint claims that the ZHB, acting under color of state law, violated its right to substantive due process, summary judgment was properly entered against Omnipoint. Thе summary judgment record reflects only a
bona fide
disagreement concerning land use planning issues. It will not support a conclusion that the ZHB has acted arbitrarily or capriciously.
See e.g. Pace Resources, Inc. v. Shrewsbury T.P.,
V.
The judgment of the District Court will be reversed and this matter will be remanded to the District Court for further proceedings consistent with this opinion.
Notes
. The ordinance has since been amended to explicitly permit personal wireless service facilities in selected areas of the Township.
. Under Pennsylvania law/ one seeking a use variance must show that the zoning restriction "inflicts unnecessary hardship on the applicant," and (1) that there are unique physical circumstances or conditions peculiar to the property that create the hardship, (2) that because of these circumstances or conditions, there is no possibility that the property can be developed in сonformity with the zoning ordinance, (3) that the applicant did not create the unnecessary hardship, (4) that the variance, if granted, would not alter the essential character of the area, and (5) that the variance, if granted, would represent the least modification possible to the regulation at issue. 53 P.S. § 10910.2.
.It is undisputed that there are no "unique physical circumstances or conditions peculiar to the property [such that] there is no possi *105 bility [of] the property [being] developed in conformity with the zoning ordinance." 53 P.S. § 10910.2.
. The Court also expressed the view that the “general concerns voiced by the Township residents” would not constitute "substantial evidence” under the TCA even if a restriction on land use could be supported by aesthetic considerations alone under Pennsylvania law. However, as we demonstrate in the text,
infra,
Op. at 105-106, the validity оf the ordinance under the Pennsylvania Constitution is not an issue that turns on adjudicative facts that require substantial record support under the TCA. The Township's zoning ordinance limiting the district to residential uses and imposing a 35 foot height restriction represents a legislative judgment about land use planning. If there are legislative facts that the decision makers could have viewed as supporting their judgment, record evidence is not required under thе TCA.
See APT Pittsburgh Ltd. v. Penn Township, Butler County,
. We recognize that the issue we here resolve is not a federal TCA issue. As we pointed out in
Penn Township,
state constitutional law issues of this kind do not come within the scope of the "substantial evidence” provision of subsection 332(c)(7)(B)(iii). This means thаt our jurisdiction to resolve it and that of the District Court emanates from 28 U.S.C. § 1367(a) (conferring supplemental jurisdic-lion to entertain a state law claim forming part of the same case or controversy).
