Alamo Rent-A-Car (“Alamo”), having lost in this court on its equal protection claim, now appeals the district court’s entry of judgment against it on its commerce clause and due process clause claims brought against the Sarasota-Manatee Airport Authority (“Authority”), the operator of the airport. We affirm the district court, with one minor exception.
I. BACKGROUND
Alamo, a rental car agency, located its operation off the premises of the Sarasota-Bradenton Airport (“airport”) in 1978. At that time, five other rental companies had “on-airport” concessions which had been obtained through competitive bidding. In 1981, without permitting competitive bidding, the Authority rolled over the existing concession contracts, and in July 1982 the Authority passed a resolution requiring the off-airport car rental companies to pay the Authority ten percent of their gross receipts obtained from customers who came from the airport. In addition, the resolution prohibited the off-airport car rental companies from soliciting business in the airport, and forbade them to pick up passengers who lacked a reservation. The resolution also prevented car rental companies from having more than one “courtesy” van at the airport terminal at any time.
Car rental companies located at the airport also pay a ten percent fee to the Authority. The on-airport companies rent counter space and parking spaces from the Authority, and they enjoy the accompanying exposure to walkup customers.
Alamo, alleging violations of the equal protection, commerce, and due process clauses of the Constitution, and the due process clause of the Florida Constitution, obtained an injunction from the district court enjoining the enforcement of the Authority’s resolution on the basis of the equal protection claim. This court, how
*518
ever, reversed on the equal protection claim, and remanded to the district court for consideration of Alamo’s due process and commerce clause claims.
Alamo Rent-A-Car v. Sarasota-Manatee Airport Auth.,
II. COMMERCE CLAUSE
Alamo challenges the Authority’s resolution, asserting that the regulations violate the commerce clause of the Constitution. We will first consider the fees charged Alamo by the Authority.
The general rule governing commerce clause review of state statutes is that
[w]here the statute regulates evenhandedly to effectuate a legitimate local public interest, and its effects on interstate commerce are only incidental, it will be upheld unless the burden imposed on such commerce is clearly excessive in relation to the putative local benefits.
Pike v. Bruce Church, Inc.,
Unquestionably, maintenance of the airport facility is a legitimate local public interest. Indeed, assuring an adequate airport facilitates rather than burdens interstate commerce.
Cf. Evansville-Vanderburgh Airport Auth. Dist. v. Delta Airlines,
The Court has noted that user fee cases are not measured by the same standard as general revenue tax cases, although in either case one of the purposes of the collection of money is to provide revenue for the collecting entity. In the case of a user fee, however, the revenue collection provides for certain services or benefits to the user.
Commonwealth Edison Co. v. Montana,
A. User Fees
In evaluating whether a user fee contravenes the commerce clause, we follow the Supreme Court’s analysis in
Evansville-Vander burgh Airport Authority District v. Delta Airlines:
first, the fee charged must “reflect a fair, if imperfect, approximation of the use of facilities for whose benefit they are imposed,”
*519 1. Fair Approximation of Use
Alamo contends that the only “use” it makes of the airport is to drive on the airport roads in order to pick up customers. Therefore, Alamo asserts, the user fee should be limited to a pro rata road use fee. Instead, the user fee is based on the receipts Alamo obtains from its airport customers. The Authority responds that Alamo is reaping the benefit of the entire airport facility because in the absence of the airport Alamo would lose a significant portion of its business. The parties are locked in battle over whether the enjoyment of the benefits conferred by the existence of the airport can constitute “use.” Because Alamo does enjoy the indirect “use” of the entire airport facility through the travelers it services, we conclude that the user fee is a fair, albeit imperfect, approximation of use.
In
Evansville-Vanderburgh Airport Authority District,
the Supreme Court held that a one dollar head tax on each enplaning passenger did not violate the commerce clause, despite the fact that it was not a perfect measure of use.
2
Here, as there, the statute does not require that all users of the airport pay the fee. In
Evansville-Vanderburgh,
myriad categories of airport users were excluded from paying the head tax, despite the fact that they “used” the airport facilities. For example, non-passengers meeting or seeing off passengers were not required to pay the head tax. The Court further stated that “since the visitor who merely sees off or meets a passenger confers a benefit on the passenger himself, his use of the terminal may reasonably be considered in the passenger’s fee.”
Recognizing that no formula to compute the fee for use of a state facility would be perfect, the Court made clear that so long as the fee was “based on some fair approximation of use or privilege for use, as was before us in
Capitol Greyhound [Lines v. Brice,
In
Capitol Greyhound,
the Court, faced with a Maryland title tax based on the cost of the vehicle, pragmatically noted that the tax “should be judged by its result, not its formula, and must stand unless proven to be unreasonable in amount for the privi
*520
lege granted.”
Complete fairness would require that a state tax formula vary with every factor affecting appropriate compensation for road use. These factors, like those relevant in considering the constitutionality of other state taxes, are so countless that we must be content with “rough approximation rather than precision.” Each additional factor adds to administrative burdens of enforcement, which fall alike on taxpayers and government.
The Court tested its ruling by the touchstone of its “general rule that taxes like [the Maryland vehicle cost title tax] are valid unless the amount is shown to be in excess of fair compensation for the privilege of using state roads.” Id. We also use that touchstone to decide whether the fee charged Alamo is in excess of fair compensation for the privilege of picking up passengers at the airport.
Alamo argues that the fee charged cannot be a fair approximation of its use of the airport because the amount of the fee varies in proportion to the revenue generated by Alamo’s airport customers. Proffering the example of two twins who arrive at the airport on the same day, Alamo notes that if one twin rents a car for only one day whereas the other twin rents a car for seven days, although each twin has made equal use of the airport, one is charged a much larger user fee than the other (based on the total rental car bill); therefore, Alamo submits, the fee does not (and cannot be construed to) represent a fair approximation of Alamo’s use of the airport.
In light of Evansville-Vanderburgh and Capitol Greyhound, however, we must disagree. In Capitol Greyhound, the title fee charged varied with the cost of the vehicle, not the use of the roads; nevertheless, the Court upheld the statute against a commerce clause challenge. In Evansville-Vanderburgh, the Court emphasized that so long as the charge was based on some “fair approximation of use or privilege for use” and is not “excessive in comparison with the governmental benefit conferred, it will pass constitutional muster, even though some other formula might reflect more exactly the relative use of the state facility by individual users.” Although imprecise in particular applications, the Authority’s decision to measure Alamo’s use of the airport facility by the gross receipts generated from Alamo’s airport customers is not irrational. The Authority could reasonably conclude that the ten percent fee on average represents Alamo’s use of the airport facility. It stands to reason that in general the more money Alamo makes from airport passengers, the more trips Alamo has made to the airport. 5 Admittedly, the formula is imperfect; it is not, however, an unfair approximation.
Furthermore, the “benefit conferred” language of
Evansville-Vanderburgh
suggests that a broad construction of use is appropriate where the benefit derived by the user depends on the existence of the entire government-provided facility. The one dollar head charge, although not necessarily related to actual use of particular airport facilities, survived challenge. A jumbo jet departing in bad weather with one passenger will pay a much smaller
*521
“user fee” than a fully loaded small jet taking off under clear skies, despite the fact that the jumbo jet has created more wear and tear and has required the use of sophisticated airport navigational aids.
Cf.
Our approach here is consonant with
Toye Bros., Yellow Cab v. Irby,
The Supreme Court precedent is clear, and we must follow it, notwithstanding any cases to the contrary decided in other circuits. Alamo argues that it is being charged for the business benefit it derives from the airport’s existence, that such a fee violates the commerce clause, and that the Ninth Circuit has rejected “business benefit” as a fair approximation of use.
See Western Oil and Gas Ass’n v. Cory,
In
Cory,
the state charged “rent” based on the volume of oil passing through an oil company pipeline located on state land. In applying the same Supreme Court precedents as we do here, the Ninth Circuit noted that it “was undisputed that the lands leased to plaintiffs are unimproved and that no services or facilities are provided by the State in conjunction with the lease.”
In sum, the user fee is a fair, albeit rough, approximation of Alamo’s “use” of the airport.
2. Reasonableness of Fees in Relation to Costs
Having determined that the fee against Alamo is assessed as a fair approximation of use, we must consider whether the fees nevertheless are excessive in relation to costs incurred by the Authority.
See Evansville-Vanderburgh v. Delta Airlines,
Alamo argues that the Authority can only “recoup” expenditures, thus implying that the Authority is restricted to seeking reimbursement for funds already expended to build and maintain the airport facility, and that the Authority is forbidden from levying a fee to fund future development. Alamo, however, misconstrues the nature of the benefit conferred. While it is true that the Authority was retaining earnings during fiscal years 1982 and 1983, the Authority was contemplating an expansion of *522 the airport facility in accordance with the Master Plan Report, and the financial projections supplied the Authority reflected that, after factoring in debt service on the Authority’s bonds and other operating expenses, the income generated by the off-airport rental car concession would be no more than 4.66% of the Authority’s total operating expenses by fiscal year 1988.
We note that in
Evansville-Vanderburgh,
the Supreme Court approved consideration of bond costs in conducting its analysis of the relation of fees to costs.
See
B. Single Van Restriction and Reservation Requirement
The resolution prohibits Alamo from having more than one van on the airport premises at a time, and Alamo argues that the resolution thus unduly burdens interstate commerce. Although Alamo may be adversely affected, the commerce clause “protects the interstate market, not particular firms, from prohibitive or burdensome regulations.”
Executive Town and Country Services v. City of Atlanta,
The reservation requirement, however, does run afoul of the commerce clause. Although the burden on interstate commerce created by the reservation requirement is not great, we can discern no local purpose that the requirement is designed to serve, nor are “putative local benefits” proffered by the Authority. The Authority contends that the burden is slight, that Alamo has not been inconvenienced, and that customers can easily make a reservation from a phone located in the airport terminal. Although those assertions may well be true, in the complete absence of any local purpose whatsoever relied upon by the Authority, we must conclude that the burden on interstate commerce is excessive.
See Minnesota v. Clover Leaf Creamery Co.,
III. DUE PROCESS
The district court properly concluded that Alamo’s claim that the ten percent fee violates due process was foreclosed by
*523
the prior panel opinion of this court where, in analyzing Alamo’s equal protection claim, we held that the fee was rationally related to a legitimate state interest.
We must also address Alamo’s contention that being excluded from competitive bidding for an on-airport location violated the standard of “fair play” exacted by substantive due process under the United States and Florida Constitutions.
7
In support of its position Alamo directs our attention to three cases, none of which is persuasive. First, Alamo asserts that the Authority’s “lock out” violated the overarching standard of “fair play” required by
Galvan v. Press,
In the absence of any authority to the contrary, we conclude that the Authority’s failure to hold competitive bidding for the on-airport concessions prior to imposing the user fee did not violate the due process clause of either the United States or Florida Constitutions.
IV. CONCLUSION
The Authority’s resolution imposing on Alamo a fee of ten percent of gross receipts derived from airport customers does not violate the due process clause of the Florida or United States Constitution, nor does it violate the commerce clause of the United States Constitution. The resolution’s single van restriction is rationally related to a valid local purpose, mitigating airport traffic congestion, and is, therefore, acceptable under the commerce clause. The reservation requirement, however, serves no local purpose, and therefore violates the commerce clause as it burdens interstate commerce without any local interest to balance the scales. Accordingly, the district court is AFFIRMED, except insofar as it ruled that the resolution’s *524 reservation requirement did not violate the commerce clause. The case is REMANDED for further proceedings consistent with this opinion.
Notes
. The Court in
Commonwealth Edison Co. v. Montana,
accepting the State’s characterization of its coal severance fee as a general revenue tax, explicitly declined to apply the tests delineated by the Court in evaluating user fees or "taxes” “designed and defended as a specific charge imposed by the State for the use of state-owned or state-provided transportation or other facilities and services.”
. In response to Evansville-Vanderburgh, Congress passed the Federal Anti-Head Tax Act, which prohibited levying fees on "persons traveling in air commerce or on the carriage of persons traveling in air commerce or on the sale of air transportation or on the gross receipts derived therefrom; _” 49 U.S.C.App. § 1513(a).
The congressional action left the Court’s commerce clause analysis undisturbed.
. At the Evansville-Vanderburgh Airport, the fee was collected by the airline, which was permitted to retain a small percentage to offset its processing costs.
. Wary of the Court’s admonition in
Commonwealth Edison Co. v. Montana
to avoid reliance on general revenue tax cases when adjudicating a user fee case, we note that the Court itself in
Evansville-Vanderburgh,
a proto-typical user fee case, found
Capitol Greyhound
pertinent. Furthermore,
Capitol Greyhound
involved a tax that was construed as being for the purpose of compensating the state for the privilege of using the state’s roads.
The Supreme Court continues to apply
Evansville-Vanderburgh
and its incorporated reference to
Capitol Greyhound
in the user fee context, although
Capitol Greyhound
is now doubtful authority in the road tax realm.
See American Trucking Ass'ns, Inc. v. Scheiner,
. This court in its previous opinion concerning Alamo’s equal protection claim noted that the user fee schedule is "well tailored" to reflect the "different benefits the various ... users received from the airport.”
. The Eleventh Circuit, in the en banc decision
Bonner v. City of Prichard,
. The Authority contends that Alamo has abandoned its claim under the Florida Constitution for failure to raise the issue in its brief. We are constrained, however, on the basis of Alamo’s citation of Florida constitutional authorities, to disagree, although the bare citations are slender reeds upon which to hang an entire constitutional argument.
