OPINION OF THE COURT

JOHN R. GIBSON, Circuit Judge.

Nextel Communications of the Mid-Atlantic, Inc., appeals from the denial of its motion for preliminary injunction against the City of Margate, New Jersey, the Zoning Board of Adjustment for the City of Margate, and A. Ralph Perone. The essence of Nextel's argument is that it is entitled to relief under the Federal Telecommunications Act of 1996, see 47 U.S.C. § 332(c)(7) (Supp. V 1999), as a result of the Defendants' efforts to reopen hearings on Nextel's construction of a previously approved telecommunications facility. Because Nextel's claims are not yet ripe, we vacate the district court's order and remand with directions to dismiss without prejudice.

On October 4, 1999, Nextel entered into a lease agreement with Margate Towers Condominium Association, Inc. The agreement gave Nextel permission to place twelve communication antennas and an eight-foot by fourteen-foot equipment cabinet on the roof of Margate Towers, an eleven-story building containing condominium units. In anticipation of the lease agreement, Nextel submitted a Staff Committee Review Application to the Land Use Administrator for the City of Margate. Nextel also submitted an Application for Action by the Zoning Board, requesting a "D Variance" to allow construction of the twelve antennas and equipment cabinet. Both applications referred to an eight-foot by fourteen-foot equipment cabinet.

A hearing before the Zoning Board was scheduled and interested property owners were given public notice. Again, both the notice and hearing agenda stated the planned equipment cabinet measured eight feet by fourteen feet. At the hearing, however, Kevin Wolfe, a land surveyor testifying on behalf of Nextel, stated the equipment cabinet would measure five and one-half feet by fourteen feet. This testimony was in accordance with plans submitted to the Zoning Board (and placed on file with the City of Margate) by Nextel.

Following the hearing, the Zoning Board unanimously approved Nextel's application, specifically referring to the equipment cabinet as eight feet by fourteen feet in its Resolution and stating that "[t]he proposed installation will be virtually invisible to any neighbors or passer-by of this site." A Notice of Decision was issued by the Zoning Board indicating issuance of the Resolution and approval of the eight-foot by fourteen-foot equipment cabinet. The forty-five day period for appealing the Zoning Board's Resolution passed without any party bringing an action seeking review, see N.J. Ct. R. 4:69-6, and Nextel was issued a building permit on February 8, 2000.

While construction was underway, Perone, a former municipal court judge in Margate who occupied the top-floor condominium immediately under the equipment cabinet, and who owned other units, brought an action in New Jersey state court seeking preliminary injunctive relief precluding Nextel from going forward with the project. He complained that: (1) Nextel's work had already damaged the roof's protective membrane, resulting in water damage to one of his units, and that further damage was likely; (2) the "equipment shack," which Nextel refused to relocate, would constitute an eyesore interfering with his use and enjoyment of his units and reducing their market value; (3) the noise from the telecommunications facility would shatter his serenity and peace, interfere with his use and enjoyment of his units, and reduce their market value; and (4) potential health hazards would exist as a result of the electromagnetic field created by the antennas. The state court denied the application for a preliminary injunction on May 8, 2000, and construction was completed May 30, 2000.

On July 13, 2000, Nextel was issued a Notice of Violation and Order to Terminate by a construction official for the City of Margate. The Notice asserted that Nextel had failed "to install the roof top structure in accordance with prior approvals and the construction documents submitted." Specifically, the equipment cabinet was said to be "approximately 3 ft 6 inches higher and 4 ft wider than approved." The Notice also stated that no Certificate of Approval would be issued until the violations were corrected, and that a penalty of five hundred dollars per week would be imposed for every week after August 4, 2000, that the violation remained outstanding. Nextel states that it thereafter provided the construction official with a copy of the Resolution, with which the equipment cabinet was in compliance, but the Notice and Order were not rescinded. Nextel also filed revised "as built" plans showing the equipment cabinet as eight feet by fourteen feet, but the Zoning Board refused to approve them. Nextel then filed an appeal with the Atlantic County Board of Appeals. Around the same time, the City of Margate also served Nextel with two complaints for violating Land Use Ordinances by failing to build in accordance with Zoning Board approval.

The Zoning Board sought a rehearing to address the situation. Nextel believed the Zoning Board had no authority to hold a second hearing, and apparently contacted John C. Matthews, the Zoning Board's attorney, to make that point. On September 19, 2000, Matthews replied with a letter to Nextel's attorney, asserting that it was "clear that the zoning board has the ability to address this situation," and that Nextel should reappear before the Zoning Board to "address the inconsistencies in [Nextel's] application and the ultimate size of the cabinet that was installed." Perone was also involved in this correspondence. On September 22, 2000, his attorney sent a letter to Matthews petitioning the Zoning Board to reconsider the Nextel application. In that letter, Perone's attorney stated that he was aware that: (1) "the City of Margate Subcode Official issued to Nextel a Notice of Violation and Order to Terminate"; and (2) that Nextel's attorney had written to Matthews arguing that it was unnecessary "for an applicant to return to the Board to be relieved of a condition of approval." Perone's attorney went on to state that "[s]hould Nextel fail to appear back before the Board when ordered to do so, the case law is clear that the Board has the authority to rescind the approval previously granted based upon the misrepresentation, whether intentional or inadvertent, made during the initial proceeding."

On September 26, 2000, Perone's attorney sent another letter to Matthews. That letter mentioned a September 22 letter sent by Nextel's attorney challenging Perone's right to petition the Zoning Board for rehearing and reiterated Perone's position on the matter. Finally, also on September 26, Matthews sent a second letter to Nextel's attorney, informing her that the Zoning Board had reviewed his letter of September 19, agreed with the contents of that letter, and was expecting Nextel "to come back before the Board on October 19, 2000 at 7:30 P.M. in order to have the Board reconsider this matter." The letter went on to state that "[t]here was clearly a mistake involving this application," because both the plans submitted by Nextel and the testimony of Nextel's witness at the hearing, referred to an equipment cabinet measuring five feet by fourteen feet, while the actual cabinet was "far larger." The letter closed by stating that if Nextel chose not to appear, "the Board has the authority to reopen this matter on its own." The day of the rehearing, Nextel brought this action in the district court, asserting that, among other things, the Zoning Board was discriminating against Nextel, prohibiting Nextel from providing services, and attempting to regulate placement of Nextel's equipment on the basis of concerns over radio frequency emissions, all in contravention of the Telecommunications Act of 1996. The telecommunications facility on top of Margate Towers remains up and running.

In Felmeister v. Office of Attorney Ethics, 856 F.2d 529 (3d Cir. 1988), we recognized that "[t]he ripeness doctrine, like other justiciability doctrines, derives ultimately from the requirement in Article III of the United States Constitution that federal courts are only empowered to decide cases and controversies. `Even when the constitutional minimum has been met, however, prudential considerations may still counsel judicial restraint.'" Id. at 535 (quoting Action Alliance of Senior Citizens v. Heckler, 789 F.2d 931, 940 n. 12 (D.C. Cir. 1986)). Ripeness is an issue we must raise sua sponte if the parties do not raise it, id., and is applicable to cases involving motions for preliminary injunction, see Acierno v. Mitchell, 6 F.3d 970, 973 (3d Cir. 1993).

The Supreme Court has explained that the basic rationale of the ripeness doctrine "is to prevent the courts, through avoidance of premature adjudication, from entangling themselves in abstract disagreements over administrative policies, and also to protect the agencies from judicial interference until an administrative decision has been formalized and its effects felt in a concrete way by the challenging parties." Abbott Lab. v. Gardner, 387 U.S. 136, 148-49, 87 S.Ct. 1507, 18 L.Ed.2d 681 (1967). In analyzing ripeness we "evaluate both the fitness of the issues for judicial decision and the hardship to the parties of withholding court consideration." Id. at 149, 87 S.Ct. 1507.

As to an issue's fitness for judicial review, we have previously stated that:

Whether a question is fit for judicial review depends upon factors such as whether the agency action is final; whether the issue presented for decision is one of law which requires no additional factual development; and whether further administrative action is needed to clarify the agency's position, for example, when the challenged prescription is discretionary so that it is unclear if, when or how the agency will employ it.

Felmeister, 856 at 535-36 (internal quotation marks omitted) (quoting Action Alliance, 789 F.2d at 940). Applying those factors to the case before us here, we conclude the issues raised by Nextel are not fit for judicial review at this time.

To begin with, the process that Nextel challenges is not final. "[T]he finality requirement is concerned with whether the initial decisionmaker has arrived at a definitive position on the issue that inflicts an actual, concrete injury. . . ." Williamson County Reg. Planning Comm'n v. Hamilton Bank, 473 U.S. 172, 193, 105 S.Ct. 3108, 87 L.Ed.2d 126 (1985). Here, the equipment cabinet remains up and running. While it is true that there was already one hearing resulting in a Resolution and that the Zoning Board has refused to approve the "as built" plans at this time, the possibility remains that the Zoning Board will approve the equipment cabinet as built following the rehearing. Cf. id. at 193-94, 105 S.Ct. 3108 ("The Commission's refusal to approve the preliminary plat does not determine that issue; it prevents respondent from developing its subdivision without obtaining the necessary variances, but leaves open the possibility that respondent may develop the subdivision according to its plat after obtaining the variances. In short, the Commission's denial of approval does not conclusively determine whether respondent will be denied all reasonable beneficial use of its property, and therefore is not a final, reviewable decision."); Felmeister, 856 F.2d at 537 ("It may be that plaintiffs' proposed advertisements will meet with the Committee's approval, and if that were the outcome of the agency action, there would indeed be no case or controversy to adjudicate because the concrete effects of the agency action would be favorable to plaintiffs."); 15 James Wm. Moore et al., Moore's Federal Practice § 101.76[1][c] (3d ed. 1997) (stating that one of the purposes of the rule requiring finality is to ensure "that the agency is not precluded from correcting any errors before rendering a final decision"). Nextel argues it is challenging the Zoning Board's authority to reopen the hearings, but merely reopening the hearings, without more, does not violate the Telecommunications Act of 1996, and violation of the Telecommunications Act of 1996 forms the basis of our jurisdiction here.

In Felmeister we concluded the second and third factors in the fitness analysis weighed in favor of allowing the administrative process to go forward because "the case presented by plaintiffs not only requires additional factual development, but the Committee has not been given the opportunity to clarify its position in this case." 856 F.2d at 537. The same is true here. Should the Zoning Board interfere with the operation of Nextel's previously approved telecommunications facility, Nextel may well have claims arising under the Telecommunications Act of 1996 and perhaps incur significant damages. However, this can only be determined after the Zoning Board reaches its ultimate decision. Cf. id. ("[W]ithout administrative action by the Committee regarding the specific advertisements proposed by the plaintiffs, the Committee's position is not only unclear, it is purely hypothetical.").

As to the hardship to the parties of withholding court consideration, we have stated that "in order for the parties' hardship to be sufficient to overcome prudential interests in deferral, that hardship must be both immediate and significant." Id. Here, as we have stated, Nextel's telecommunications facility received the necessary administrative clearance, in addition to the Zoning Board's decision, and remains up and running. Nevertheless, Nextel claims that allowing the rehearing to go forward exposes it to hardship in the form of time and expense, as well as the possibility of further litigation. However, "we do not believe that such harm . . . is sufficiently strong to outweigh the unfitness for review we have already described." Id. at 538; cf. Ohio Forestry Ass'n, Inc. v. Sierra Club, 523 U.S. 726, 735, 118 S.Ct. 1665, 140 L.Ed.2d 921 (1998) ("The ripeness doctrine reflects a judgment that the disadvantages of a premature review that may prove too abstract or unnecessary ordinarily outweigh the additional costs of — even repetitive — postimplementation litigation.").

II.

In accordance with the above, we vacate the district court's order on Nextel's motion for preliminary injunction and remand with directions to dismiss Nextel's claims without prejudice.
