OPINION OF THE COURT

The Development Group, LLC and Parsons Road Development Group, Ltd. (together, “Development Group”), own two adjacent parcels of land on Miller Farm in Franklin Township, Pennsylvania. The Franklin Township Board of Supervisors rejected Development Group’s application for preliminary approval of its plan to develop the Miller Farm parcels. Development Group appealed the denial to the Court of Common Pleas for Chester County and the Commonwealth Court; both courts affirmed the Board of Supervisors’ decision. As its appeal was pending in the Pennsylvania courts, Development Group filed a complaint against the Board of Supervisors, the Franklin Township Planning Commission, various individual members of those bodies (the “Township Defendants”), and John S. Halsted, the Township Solicitor, in the District Court for the Eastern District of Pennsylvania, alleging violations of its rights to procedural due process, substantive due process and equal protection. The District Court resolved these claims by granting the Township Defendants’ motion to dismiss the proce *160 dural due process and equal protection claims, Dev. Group, LLC v. Franklin Twp. Bd. of Supervisors, 2003 WL 22358440, at *11 (E.D.Pa. Sept. 24, 2003), and granting Halsted’s and the Township Defendants’ motions for summary judgment on the substantive due process claim. Dev. Group, LLC v. Franklin Twp. Bd. of Supervisors, 2004 WL 2812049, at *22 (E.D.Pa. Dec. 7, 2004).

Development Group now appeals the District Court’s order granting summary judgment in favor of the Defendants on the substantive due process claim. The District Court concluded, in a thorough and well-reasoned opinion, that Development Group has not raised a genuine issue of material fact as to whether Defendants’ actions violated Development Group’s substantive due process rights. We agree and will affirm.

To succeed on a substantive due process claim in the land use setting, a plaintiff must allege and prove executive action that “shocks the conscience.” United Artists Theatre Circuit, Inc. v. Twp. of Warrington, PA 316 F.3d 392, 401 (3d Cir. 2003). Although “the meaning of this standard varies depending on the factual context,” id. at 400, it “encompasses ‘only the most egregious official conduct.’ ” Id. (quoting County of Sacramento v. Lewis, 523 U.S. 833, 846, 118 S.Ct. 1708, 140 L.Ed.2d 1043 (1998)). Under this demanding standard, we have little difficulty upholding the District Court’s determination that none of the facts advanced by Development Group in this case rises to the level of conscience-shocking behavior.

Development Group’s claim is based on three purported examples of “conscience-shocking” behavior by the Defendants: (1) self dealing by the Board in rezoning the Miller Farm properties to benefit members of the Planning Commission; (2) attempted bribery by Township officials who offered to give Development Group priority in future Township development projects if they would abandon the Miller Farm plans; and (3) Halsted’s suggestion that the parties wait to negotiate until after the plans were rejected to avoid application of the Pennsylvania Sunshine Act, 65 Pa. Cons.Stat. § 701 et seq. 1

We need not decide whether the type of self dealing that Development Group asserts, if true, would shock the conscience because we agree with the District Court that Development Group has proffered insufficient evidence to support its theory. See id. at *16. Its assertions that the Board of Supervisors rezoned the Miller Farm property to benefit members of the Planning Commission amount to no more than conjecture. “Mere speculation about the possibility of existence of such facts does not entitle [plaintiffs] to go to trial.” Sterling Nat’l Mortgage Co. v. Mortgage Corner, Inc., 97 F.3d 39, 45 (3d Cir. 1996).

As for Development Group’s claims of attempted bribery and violation of the Pennsylvania Sunshine Act, we cannot discern anything conscience-shocking in the behavior of which Development Group complains. Rather, we interpret the Township’s efforts to offer Development Group other development projects and Halsted’s proposal that the parties should enter into settlement negotiations once the plans were rejected as reasonable at *161 tempts to resolve the dispute over the Miller Farm property. Moreover, as the District Court noted, there is no evidence that any of the Defendants actually did anything illegal. See Dev. Group, 2004 WL 2812049, at *17,18 n. 18. We therefore agree with the District Court that, “[ejven when taken as a whole, Defendants’ conduct, though harsh, was not so extreme as to shock the conscience.” Dev. Group, 2004 WL 2812049, at *18.

Although it has set forth various ways in which it contends that the Township’s actions shock the conscience, the essence of Development Group’s complaint appears to be that the Township never intended to allow it to develop the Miller Farm property. Because its preliminary plans conformed to the applicable zoning scheme-“high density residential” or “HDR”-Development Group claims that it was entitled to approval “by right.” However, the Court of Common Pleas and the Commonwealth Court held that the Board of Supervisors acted within its rights and in accordance with Pennsylvania law when it denied Development Group’s plans.

Our decision in United Artists Theatre Circuit, Inc. v. Township of Warrington makes clear that federal courts are not to be “cast in the role of a ‘zoning board of appeals.’ ” 316 F.3d at 402 (quoting Creative Env’ts, Inc. v. Estabrook, 680 F.2d 822, 833 (1st Cir. 1982)). “Land-use decisions are matters of local concern, and such disputes should not be transformed into substantive due process claims based only on allegations that government officials acted with ‘improper’ motives.” Id. Given the state courts’ rulings upholding the local officials’ action and the strength of our previous pronouncements on this issue, we have trouble understanding why the parties continue to press what essentially amounts to an appeal from local zoning decisions in federal court.

For the foregoing reasons, we conclude that there is no genuine issue of material fact as to whether Defendants’ actions shock the conscience, even when viewed in the light most favorable to Development Group, and that Defendants are entitled to judgment as a matter of law. We have considered all of the other arguments advanced by the parties and conclude that no further discussion is necessary. Accordingly, we will AFFIRM the judgment of the District Court.
