Aрpellants William St. Clair and John Shelton timely appeal an order of the district court dismissing their complaint because it considered their claims not ripe for adjudication. Appellants assert that the district court erred both in its legal conclusion and in basing its decision on facts not alleged in the cоmplaint, at least without first permitting discovery. The district court had jurisdiction of this case pursuant to 28 U.S.C. § 1331 (1982) and our jurisdiction rests on 28 U.S.C. § 1291 (1982). We affirm.
I
Appellants brought this action under 42 U.S.C. § 1983 (1982) alleging that the City of Chico’s (“City”) and the County of Butte’s (“County”) refusals either to connect Appellants’ proposed real estate projeсt to an existing sewer system or allow them to construct their own treatment facility effected an unconstitutional taking of their property and also deprived them of their constitutional rights to due process and equal protection of the laws. Appellants alleged in their complaint that they began the permitting process for approval of their proposed “Ravenwood” development by first receiving a required zoning change from the County. As a condition to that zoning change, however, the County required Appellants to connect their project to the City’s sewer system. According to the allegations of the complaint, the City initially approved Appellants’ application for a sewer connection, but subsequently conditioned its approval on the County’s political concessions to matters that allegedly were unrelated to the merits of the Ravenwoоd development. Appellants further alleged in their complaint that the County would not accede to these conditions, nor would the City permit the sewer connection without them. Fearing an impasse, Appellants sought the County’s approval for the construction of an independent sewage treatment facility. But the County, allegedly in a final decision from which no appeal or variance was possible, refused the application and continued to condition approval of the project on its connection to the City’s sewer system. According to the complaint, similar рrojects received the County’s approval for the construction of independent treatment facilities. The complaint concludes that the impasse reached between the City and the County ultimately caused Ravenwood to enter bankruptcy.
*201 Both the City and the County filed motions of dismissal contending either that, under Fed.R.Civ.P. 12(b)(6) Appellants were not entitled to relief, or that under Fed.R.Civ.P. 12(b)(1) the district court was without federal jurisdiction. The City contested the complaint’s factual allegations that approval of the sewer connection was all but complete before the dispute between the City and the County arose. Rather, the City referred to evidence in the record that approval of the connection depended, at least in part, on the annexation of the Ravenwood project to the City. In addition, both the City and the County contested the complaint’s factual аllegations that an impasse had been reached on the alleged political concessions. Both parties contended that discussions were continuing and that Appellants were never led to believe by either party that their project would not ultimately receive the necessаry approval. The district court concluded that Appellants’ claims were not ripe for adjudication both because there was never a “final decision” rejecting the proposed sewer connection and because Appellants’ failure even to attempt annexatiоn belied their argument that annexation would have been futile. Accordingly, the district court dismissed Appellants’ complaint for lack of subject matter jurisdiction pursuant to Fed. R.Civ.P. 12(b)(1).
II
The main issue in this case is accompanied by a procedural problem that we consider first. Appellants note that the district court’s decision dismissing their complaint expressly rested on exhibits outside the complaint. Appellants argue that the decision is in error because the district court failed to assume the truth of th< facts alleged in the complaint and tha those facts do not support its conclusion. The district court did not err.
Whether a claim is ripe for adjudication goes to a court’s subject matter jurisdiction under the case or controversy clause of article III of the federal Constitution.
Unity Ventures v. County of Lake,
There are only a few procedural limitations placed on a district court when it faces a factual challenge to a complaint’s jurisdictional allegations.
See
C. Wright & A. Miller,
supra,
§ 1350, at 558-59;
see also Crawford v. United States,
Appellants argue next that the district court should have reserved decision on the jurisdictional issue until after a complеted trial on the merits. They concede that ordinarily the issue of jurisdiction is for the district judge to decide, but they contend that a jurisdictional issue that is “intertwined” with the merits must be decided by a jury and, as a result, must await trial on the merits. The problem with Appellants’ argument is that “the jurisdictional issue and the issue on the merits are [not] factually so ‘completely intermeshed,’
McBeath v. Inter-American Citizens for Decency Committee,
Ill
The focus of this appeal is on the district court’s legal conclusion that Appellants’ claims against the City and the County were not ripe for adjudication. We review this decision de novo.
Kinzli v. City of Santa Cruz,
The purpose of the ripeness doctrine is to avoid premature judicial review of administrative action. This goal is accomрlished by deferring review of a planning commission’s land use decisions until they represent a “ ‘final, definitive position regarding how it will apply the regulations at issue to the particular land in question.’ ”
MacDonald, Sommer & Frates v. County of Yolo,
Appellants argue here that the district court erred in conсluding that each of its claims failed to satisfy these requirements. There is no question that this case does not concern the submission, consideration, and rejection of a “development plan,” as in
Herrington
and
Kinzli.
Appellants contend nonetheless that the finality requirement can be met “by a rejected application or proposal for [a sewer] connection,”
Unity Ventures v. County of Lake,
Regarding the claim against the County, Appellants assert that they sought approval for the construction of an independent treatment facility but were turned away in a final decision from which no variance was possible. The district court concluded otherwise, apparently believing that the County rejected Appellants’ claim only becaus: it believed they had not yet received rejection from the City on their аpplication for a connection to the City’s sewer system. Presumably, then, if the City had ultimately rejected that proposal the County would have reconsidered its position regarding Appellants’ application for the construction of an independent treatment facility. Undisputed material in thе record supports such a determination. Exhibit E, attached to the Declaration of David M. Coyne, Appellants’ own attorney, indicates that the Planning Commission recommended approval of the proposed treatment facility, but only on condition that, among other things, “all efforts” must first “have been exhausted with the City of Chico to get approval of the hookup to the sewer system.” This evidence suggests that the County merely postponed serious consideration of Appellants’ application until they exhausted all opportunity of succeeding on their alternative proposаl.
Regarding their claim against the City, Appellants argue essentially that the City placed two conditions on the acceptance of their application for a sewer connection: first, the County’s concessions to political demands, and second, Appellants’ annexation of their property to the City. Appellants argued below, and reassert here, that because the first condition could never be satisfied their compliance with the second condition would have been futile. We need not address Appellants’ futility argument, however, because we believe the City and the County had not reached an impasse regarding the negotiations on the political concessions. Therefore, they could have ultimately reached an agreement that would have satisfied the first condition to Appellants’ application. Undisputed material in the record supports this conclusion, too. Responding to Appellants’ inquiry into the progress of their application, the City wrote that it was inappropriate “at [that] time” to consider the merits of their application pending intensive study and discussion with the County “during the com-ng months.” A letter from the County similarly indicated that negotiаtions between the two entities were continuing. The proper inference from both communications is not only that an agreement was possible, but even likely. 1 Appellants nev *204 er offered any evidence below to rebut this inference, nor did they offer any support for their allegations that the two entities reached an impasse. Under these circumstances it is obvious to us that Appellants failed to satisfy their burden of showing that their application for a connection to the City’s sewer system was rejected in a final, definitive decision.
Appellants’ claim for the taking of their property without just compensаtion is, obviously, not ripe for these same reasons. Neither the City nor the County reached, final, definitive positions rejecting either of Appellants’ two alternative proposals for obtaining sewer service to their property. Until both alternatives were foreclosed, Appellants cеrtainly could not have been deprived of “all use of [their] property,” as they allege in their complaint.
First English Evangelical Lutheran Church of Glendale v. County of Los Angeles,
IV
The district court properly dismissed Appellants’ cоmplaint under Fed.R.Civ.P. 12(b)(1) on the ground that their claims were not ripe for adjudication.
AFFIRMED.
Notes
. Appellants do not suggest that their takings claim is based on a considerably "excessive delay” in the application process, and would find it impossible to do so because, as we have stated before, a delay of up to eight years may still be inadequate to satisfy the ripeness requirement.
