OPINION
Eugene George Breza pleaded guilty to manufacturing 100 or more marijuana plants, see 21 U.S.C.A. § 841(a)(1) (West 1999), reserving the right to appeal the denial of his motion to suppress. He now argues that his right to be free from unreasonable searches and seizures was violated when law enforcement officers conducted aerial surveillance of his property and subsequently entered, and seized marijuana plants from, a vegetable garden that Breza asserts was within the curtilage of his home. For the reasons set forth below, we affirm.
I.
Breza owns a 92-acre farm in Gilmer County, West Virginia. Only part of this land, surrounding the house, is landscaped. This area consists of a lawn and a vegetable garden from which the marijuana was seized. The house and the landscaped portion of the yard are surrounded by a perimeter fence made of posts and wire. The lawn extends approximately 50 feet from the back of the house to the vegetable garden, which is separated from the lawn by a post-and-wire fence with a gate; the perimeter fence doubles as the back fence of the garden. In addition to the fence, an ornamental garden and several trees separate the vegetable garden from the lawn. 1 The portion of the vegetable garden where the marijuana was growing was shielded by artichokes plants and *433 grapevines, so that the marijuana could not be viewed from outside the garden by one standing on Breza’s lawn.
While conducting a routine drug interdiction operation, law enforcement officers flew over Breza’s property in a helicopter at a height of approximately 500 feet. When one of the officers observed what he believed to be marijuana growing in the garden, the helicopter pilot descended to approximately 200 feet above the property. 2 After confirming the presence of marijuana, the helicopter ascended to navigable airspace and radioed nearby officers stationed on the ground, who immediately proceeded to Breza’s property. Officers searched the garden and seized several hundred marijuana plants.
After he was indicted, Breza moved to suppress the marijuana on the basis that the aerial surveillance of his property and the warrantless entry of his vegetable garden violated his Fourth Amendment rights. Following a hearing, the district court rejected both arguments and denied the motion to suppress. Breza thereafter entered a conditional guilty plea.
II.
The Fourth Amendment guarantees “[t]he right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures” by governmental actors. U.S. Const, amend. IV. The “touchstone” of Fourth Amendment analysis is whether the individual has a reasonable expectation of privacy in the area searched,
Oliver v. United States,
A.
Breza first maintains that the aerial surveillance of his property violated his Fourth Amendment rights because the surveillance constituted a warrantless search of the curtilage of his home.
See Oliver,
On two occasions, the Supreme Court has addressed the question of whether aerial surveillance of property violates an expectation of privacy that society is prepared to recognize as reasonable.
See Florida v. Riley,
Breza contends that reversal is mandated under Justice O’Connor’s concurrence in Riley. His argument, however, rests almost entirely on the factual assertion that the helicopter violated FAA regulations by flying as low as 35 feet over his property. The district court rejected Breza’s testimony and found that the helicopter fully complied with applicable regulations regarding proper altitude. Additionally, testimony from law enforcement officers established that such flights were a regular occurrence in the area where Breza’s farm was located. 3 We therefore *435 conclude that the aerial observation of Breza’s property did not violate his Fourth Amendment rights.
B.
Breza next contends that the law enforcement officers’ warrantless entry into the vegetable garden violated- his Fourth Amendment rights. The question of whether Breza had a legitimate expectation of privacy in his garden turns upon whether the garden was within the curti-lage of the house or, conversely, was an “open field” not subject to the protection of the Fourth Amendment.
See Oliver,
curtilage questions should be resolved with particular reference to four factors: the proximity of the area claimed to be curtilage to the home, whether the area is included within an enclosure surrounding the home, the nature of the uses to which the area is put, and the steps taken by the resident to protect the area from observation by people passing by.
The Court cautioned, however, that “these factors are useful analytical tools only to the degree that, in any given case, they bear upon the centrally relevant consideration — -whether the area in question is so intimately tied to the home itself that it should be placed under the home’s ‘umbrella’ of Fourth Amendment protection.” Id.
A dispute exists among the circuits regarding the proper standard to be applied in reviewing a curtilage determination by the district court.
See generally United States v. Johnson,
1. Proximity
“There is not ... any fixed distance at which curtilage ends.”
United States v. Depew,
2.Enclosure
Next, we must consider “whether the area is included within an enclosure surrounding the home.”
Dunn,
3.Use of Property
The third
Dunn
factor concerns the use of the area claimed to be curtilage. In
Dunn,
the Supreme Court deemed it “especially significant” that law enforcement officials “possessed objective data indicating that” the area claimed to be curti-lage was being used for the production of illicit drugs and not for “intimate activities of the home.”
Dunn,
4.Visibility
Finally, we must consider the steps taken by Breza to shield the vegetable garden from the view of passersby. We conclude that this factor weighs against a determination that the garden was within the curtilage of Breza’s home. Breza did choose his home place because of the remote location.
See Depew,
5.Conclusion
Having considered all of the
Dunn
factors, we conclude that Breza’s vegetable
*437
garden was not “so intimately tied to the home itself that it should be placed under the home’s ‘umbrella’ of Fourth Amendment protection.”
Dunn,
III.
For the reasons set forth above, we conclude that neither the aerial surveillance of Breza’s property nor the warrant-less entry into his vegetable garden infringed upon Breza’s Fourth Amendment rights. We therefore affirm the denial of the motion to suppress.
AFFIRMED.
Notes
. The record does not contain information regarding the size or dimensions of the vegetable garden or the amount of produce it yielded.
. Breza testified that the helicopter descended much lower, to less than 100 feet and perhaps as low as 35 feet. The district court credited the Government's version of events, however.
. In his brief, Breza claims to have testified at the suppression hearing that "overflights by helicopter over his property were definitely rare.” Br. of Appellant at 17. This is not exactly what Breza said, however. Breza’s testimony did not refer to helicopter flights generally, but rather was given in response to the specific question of whether it was usual *435 for helicopters to fly over his property at the claimed altitude of 35 feet.
