MEMORANDUM*
UNITED STATES OF AMERICA; THE

THE UNITED STATES OF AMERICA;
THE NATIONAL PARK SERVICE OF THE
UNITED STATES OF AMERICA; CITY
AND COUNTY OF SAN FRANCISCO,
Defendants-Appellees.
Appeal from the United States District Court
for the Northern District of California
Trina L. Thompson, District Judge, Presiding
Argued and Submitted October 25, 2024
San Francisco, California
Before: CLIFTON, SUNG, and SANCHEZ, Circuit Judges.
Marie Thornton appeals the district court’s dismissal of her action against
both the United States of America (USA) and the City of San Francisco (City).
*
This disposition is not appropriate for publication and is not precedent
except as provided by Ninth Circuit Rule 36-3.
This court has jurisdiction over the appeal under 2828 U.S.C. § 1291. We affirm.
Grants of motions to dismiss under both Rule 12(b)(1) and 12(b)(6) are
reviewed de novo. Banks v. N. Tr. Corp., 929 F.3d 1046, 1049 (9th Cir. 2019);
Mudpie, Inc. v. Travelers Cas. Ins. Co. of Am., 15 F.4th 885, 889 (9th Cir. 2021).
“We review the district court’s underlying factual findings on jurisdictional issues,
however, for clear error.” SEC v. World Cap. Mkt., Inc., 864 F.3d 996, 1003 (9th
Cir. 2017).
First, we review the dismissal of the claim against the USA. The federal
government is protected by sovereign immunity. Under the Federal Tort Claims
Act, the USA waives that immunity for tort claims “if a private person[] would be
liable to the claimant in accordance with the law of the place where the act or
omission occurred.” 28 U.S.C. § 1346(b)(1). Like any private owner which opens
its land for recreational use, the USA is protected by California’s recreational
immunity statute. See Cal. Civ. Code § 846. Section 846 provides immunity for
“real property” owners who allow “entry or use by others for any recreational
purpose.” Cal. Civ. Code § 846.1 Thornton’s claim is barred because it meets all
1
“An owner of any estate or any other interest in real property, whether possessory
or nonpossessory, owes no duty of care to keep the premises safe for entry or use
by others for any recreational purpose or to give any warning of hazardous
conditions, uses of, structures, or activities on those premises to persons entering
for a recreational purpose, except as provided in this section.” Cal. Civ. Code
§ 846(a).
2 23-3969
three requirements: (1) entry or use of (2) real property for (3) a recreational
purpose.
The district court concluded that Thornton was a recreational user because
she was injured while walking to take pictures at the Legion of Honor. The district
court reasoned that because taking pictures is “akin to ‘sightseeing,’” Thornton
was engaged in a recreational purpose. See Cal. Civ. Code § 846(b) (defining
“recreational purpose” to include “sightseeing”). Thornton does not dispute that
conclusion on appeal.
Real property includes “[t]hat which is affixed to land.” Cal. Civ. Code
§§ 658, 660 (defining fixtures). California courts interpret this definition to include
fences. See Allen v. McMillion, 82 Cal. App. 3d 211, 218 n.5 (Cal. Ct. App. 1978)
(“Damage to fence and foliage in the circumstances alleged is damage to real
property.”); Krouser v. San Bernardino Cnty., 178 P.2d 441, 443 (Cal. 1947)
(holding that “[r]eal property . . . is all-inclusive and contemplates both land and
improvements” including “fences”). The fence that Thornton tripped over was real
property of the United States. Indeed, the premise of Thornton’s claim is that the
USA had a duty to maintain the fence because it was federal property.
Section 846 explicitly protects against recreational users who enter or use
real property. See Cal. Civ. Code § 846(a) (“An owner of . . . any other interest in
real property . . . owes no duty of care to keep the premises safe for entry or use by
3 23-3969
others for any recreational purpose. . . .”). Thornton alleges that she tripped when
she stepped onto the fence as she attempted to enter federal property. It does not
matter that Thornton’s injuries, allegedly caused by the fence, were alleged to have
occurred on the City’s side of the property line between the City and federal land.
Her injuries occurred because she was attempting to enter the USA’s property for a
recreational purpose, and the statute provides that the USA owes no duty of care to
keep the premises, including the fence, safe for her entry or use.
The “purpose of section 846 is to encourage property owners to allow the
general public to recreate free of charge . . . on privately owned property.”
Hoffmann v. Young, 515 P.3d 635, 641 (Cal. 2022) (internal quotations omitted).
Holding a property owner liable for injuries suffered by a recreational user, such as
Thornton, would undermine the purpose of the statute and discourage owners from
permitting access to recreational users. Thornton’s argument that the protection
afforded by the statute does not apply to her injury because the injury occurred just
outside the boundary line does not reasonably follow from either the language or
the logic of section 846.
Next, we review the dismissal of the state law claim against the City. The
only ground asserted for federal court jurisdiction over that claim was the existence
of Thornton’s claim against the USA. Because Thornton’s federal claim was
properly dismissed for lack of subject matter jurisdiction, the district court lacked
4 23-3969
supplemental jurisdiction over her state law claim against the City. It must be
dismissed as well. Herman Fam. Revocable Tr. v. Teddy Bear, 254 F.3d 802, 806
(9th Cir. 2001). Thornton may proceed with her action already pending against the
City in state court, but we affirm the dismissal of her federal court claim against
the City, without prejudice.2
AFFIRMED.

The City’s motion for judicial notice (Dkt. No. 47) is granted.
