The issue presented at this stage of this original action is
whether -- for purposes of determining California's ownership under
the Submerged Lands Act of submerged lands and natural resources
lying within three geographical miles seaward of the California
coastline -- the coastline follows the mean lower low-water line
along the natural shore, or whether it follows the seaward edge of
15 piers and the Rincon Island complex projecting into the sea from
the shore. Rincon Island, a privately owned artificial "island"
used to service offshore oil facilities, is erected upon
foundations resting on the ocean floor, has a dock on the seaward
side, and is connected to the mainland by a causeway structure
under which water flows freely. Neither the causeway nor the island
have had any noticeable effect on the shoreline, and the complex is
not a coast protective work. The piers in question, some of which
are privately owned and some of which are operated by the State as
docking facilities or for recreational purposes, are all attached
to the mainland; water flows freely underneath each; they have no
effect on the shoreline, and are not coast protective works. The
Special Master concluded that the piers and the Rincon Island
complex do not constitute extensions of the coast, and that the
coastline follows the natural coast in the vicinity of these
structures. California filed an exception to the Master's
report.
Held: The Special Master's conclusion is proper. Under
the Convention on the Territorial Sea and the Contiguous Zone,
which is used for guidance
Page 447 U. S. 2
in defining "coastline" for purposes of the Submerged Lands Act,
the general rule expressed in Art. 3 therein is that the
"normal baseline for measuring the breadth of the territorial
sea is the low-water line along the coast as marked on large-scale
charts officially recognized by the coastal State."
Although the type of construction of the open piers involved
here, being elevated above the ocean's surface on pilings, does
not, without more, require a determination adverse to California,
the absence of a "lower low-water line" deprives them of a "normal
baseline," and precludes them from falling within the ambit of Art.
3. Moreover, Art. 8 of the Convention, whereby "the outermost
permanent harbour works which form an integral part of the harbour
system shall be regarded as forming part of the coast," does not
encompass all structures erected on the shore. The structures in
this case are not harbors, and are not a part of outermost "harbour
works," since they neither "protect," "enclose," nor "shelter,"
Louisiana Boundary Case, 394 U. S. 11,
394 U. S. 37, n.
42, and thus they cannot constitute an integral part of a harbor
system. Nor does the Longshoremen's and Harbor Workers'
Compensation Act and decisions thereunder indicate that Congress
has withdrawn from the courts the authority to define "coastline"
for purposes of the Submerged Lands Act. Pp.

MR. CHIEF JUSTICE BURGER delivered the opinion of the Court.
I
The United States began this original action against the State
of California under Art. III, § 2, of the Constitution in 1945 to
determine whether the right to exploit natural resources under the
submerged lands off the California coast belongs to the United
States or to California.
In 1947, this Court decreed that the United States owned all
submerged lands extending seaward of the ordinary low-water mark on
the California coast.
United States v. California,
332 U. S. 804,
332 U. S. 805.
See also United States v. California, 332 U. S.
19 (1947). When Congress enacted the Submerged Lands Act
of 1953, 67 Stat. 29, 43 U.S. C § 1301
et seq., the United
States, in effect, quitclaimed to California whatever interest the
Federal Government may have had in, and to, all lands and natural
resources lying within three geographical miles seaward of the
California coastline. § 3(b)(1), 43 U.S.C. § 1311(b)(1). Congress
subsequently enacted the Outer Continental Shelf Lands Act of 1053
67 Stat. 462, 43 U.S.C. § 1331
et seq., which declared
that the United States owned all submerged lands seaward of those
granted to California by the Submerged Lands Act. §§ 1332,
1333.
In 1978, the parties filed cross-motions for entry of a
supplemental decree. Although those motions proposed three issues
for resolution, only one is presently before the Court. [
Footnote 1] That issue is whether the
coastline follows the mean lower low-water line along the natural
shore, or whether it follows the seaward edge of 15 piers and the
Rincon Island complex projecting into the sea from the shore.
Page 447 U. S. 4
This Court appointed a Special Master who received evidence and
submitted recommendations. The Master made the following findings
of fact:
Rincon Island is a privately owned artificial "island" off the
shore near Punta Gorda, Ventura County, which is used to service
offshore oil facilities. It is built upon large concrete tetrapods
[
Footnote 2] which rest on the
ocean floor, and it has a surface consisting of rock and dirt fill.
There are buildings and other structures on the island, all of
which are related to an active oil well. On the seaward side of the
island is a large dock equipped with hardware for the berthing of
vessels.
The island is connected to the mainland by a structure commonly
known and identified on maps as the Punta Gorda Causeway. Oil is
pumped to shore by a pipeline running beneath and alongside the
causeway structure. The wooden causeway deck surface rests on a
steel frame supported by pilings filled with gravel and capped with
concrete. Water flows freely underneath. Neither the structure nor
the island has had any noticeable effect on the shoreline, and the
complex is not a coast protective work. [
Footnote 3]
The 15 piers have asphalt, wood or concrete deck surfaces
mounted on precast concrete, steel, or wood pilings. They vary in
length from 500 feet (at the Santa Barbara Biltmore Hotel) to 3,500
feet (at Ocean Beach). All are attached to the mainland, and water
flows freely underneath each. The piers have no effect on the
shoreline; they are not coast protective works. One pier is
privately owned by a hotel; [
Footnote 4] others are privately owned and used to supply
offshore oil rigs; the remaining 11 are operated by the California
State
Page 447 U. S. 5
Department of Parks and Recreation as docking facilities or for
recreational purposes.
The Special Master concluded that neither the Rincon Island
complex nor the piers constitute extensions of the coast. [
Footnote 5] The California coastline,
he determined, follows the natural coast in the vicinity of these
structures for purposes of measuring to the federal-state boundary
under the Submerged Lands Act. California filed an exception to the
Master's conclusion.
II
Since passage of the Submerged Lands Act granting California and
other States ownership of submerged lands within three miles of
their respective coasts, this Court has adverted to the Convention
on the Territorial Sea and the Contiguous Zone, Apr. 29, 1958,
[1964] 15 U.S.T. 1606, T.I.A.S. No. 5369, for guidance in the
definition of the term "coastline."
See Louisiana Boundary
Case, 394 U. S. 11
(1969);
United States v. California, 381 U.
S. 139,
381 U. S. 165
(1965). The definitional contexts tend to be highly fact-bound,
[
Footnote 6] and the Convention
provides no rule for automatic application. The Submerged Lands Act
does not indicate whether the word "coast" was intended by Congress
to encompass only the natural shore or to include structures
extending seaward from shore. Although we have recognized in
earlier proceedings of this case that some kinds of structures may
modify the
Page 447 U. S. 6
California coastline,
see the 1977 decree,
432 U. S. 432 U.S.
40, this Court has never adopted a view that all structures erected
on the coast may be considered extensions of the coast.
Open piers, such as those at issue here, are elevated above the
surface of the ocean on pilings. Accordingly, they do not conform
to the general rule for establishing a baseline from which to
measure the extent of a coastal state's jurisdiction. That rule,
contained in Art. 3 of the Convention, states:
"[T]he normal baseline for measuring the breadth of the
territorial sea is the low-water line along the coast as marked on
large-scale charts officially recognized by the coastal State."
The type of construction of the piers does not, without more,
require a determination adverse to California.
See, e.g.,
United States v. California, 381 U.S. at
381 U. S.
176-177. But the absence of a "lower low-water line"
deprives the piers of a "normal baseline," and precludes them from
falling within the ambit of Art. 3.
The ultimate conclusion of the Special Master implicitly
recognizes this proposition. He did not view the discontinuity of
the waterline as dispositive, correctly noting that some
breakwaters, for example, also have discontinuous waterlines, and
have been held to be part of the coastline. But by considering and
disposing of California's claim under Art. 8 of the Convention, in
effect on exception to the general rule embodied in Art. 3,
see discussion
infra, he necessarily found the
criteria of Art. 3 were not satisfied.
The fact that every National Ocean Survey chart of the
California coast "officially recognized" by the United States
displays a black line connoting the coastal low-water mark
following the configuration of the seaward edge of the 16
structures, as it does groins, breakwaters, and other structures
that extend seaward, is likewise not dispositive. We agree with the
Master's finding that the charts contain an aggregate of errors,
and in many places depict the territorial sea without
Page 447 U. S. 7
regard to the coastline. And each chart, as the Master found,
includes a disclaimer to that effect.
California suggests that Art 8 of the Convention also affords
support for its position. Article 8 provides:
"For the purpose of delimiting the territorial sea, the
outermost permanent harbour works which form an integral part of
the harbour system shall be regarded as forming part of the
coast."
Although, in an earlier stage of this litigation, we
incorporated this text into the decree,
382 U. S. 382 U.S.
448,
382 U. S. 449
(1966), we did not construe the language as encompassing all
structures erected on the shore.
The piers and the island complex involved in this case are not a
part of outermost harbor works; nor do they form an integral part
of a harbor system. We held in the
Louisiana Boundary Case,
supra, that the term "harbour works" refers to
"'[s]tructures erected along the seacoast at inlets or rivers
for protective purposes, or for enclosing sea areas adjacent to the
coast to provide anchorage and shelter.'"
394 U.S. at
394 U. S. 37, n.
42. [
Footnote 7] These
structures neither "protect," "enclose," nor "shelter"; [
Footnote 8] they do not constitute
harbor works within the meaning of Art. 8.
A "harbor" under Art. 8 is a body of water providing a haven for
safe anchorage and shelter for vessels.
See Louisiana Boundary
Case, supra at
394 U. S. 37, n.
42, citing 1 A. Shalowitz,
Page 447 U. S. 8
Shore and Sea Boundaries 60, n. 65 (1962). That the piers and
the Rincon Island complex provide no protection has been noted;
that they are not bodies of water states the obvious. It follows
that, since the structures are neither harbor works nor harbors,
they cannot constitute an integral part of a harbor system.
The State seeks to import language from the International Law
Commission's Commentary to the final draft of Art. 8, primarily
Comment 2, Report of the International Law Commission to the
General Assembly, U.N.Gen.Ass.Off.Rec., 11th Sess., Supp. No. 9,
U.N.Doc. A/3159, p. 16 (1956), as support for its position that
Art. 8 should be construed to cover these structures. Comment 2
states:
"Permanent structures erected on the coast and jutting out to
sea (such as jetties and coast protective works) are assimilated to
harbour works."
Comment 2 has been held to envision erosion jetties, but we have
highlighted the beach protection or harbor protection role they
fulfill as well.
Louisiana Boundary Case, supra at
394 U. S. 49-50,
n. 64. A construction of the Comment as including these piers and
the island complex which concededly do not fulfill such a role
would unwarrantedly extend the most generous intimation of the
Comment. [
Footnote 9]
Finally, the State relies upon decisions in which the
Longshoremen's and Harbor Workers' Compensation Act, 44 Stat. 1424,
33 U.S.C. § 901
et seq., was applied to accidents which
occurred on piers as evidence that Congress intended domestic,
rather than admiralty, law to control judicial construction of
Page 447 U. S. 9
the Submerged Lands Act.
E.g., Nacirema Co. v. Johnson,
396 U. S. 212
(1969);
Travelers Insurance Co. v. Shea, 382 F.2d 344 (CA5
1967);
Michigan Mutual Liability Co. v. Arrien, 344 F.2d
640 (CA2 1965);
East v. Oosting, 245 F. Supp.
51 (ED Va.1965);
Johnson v. Traynor, 243 F.
Supp. 184 (Md.1965). It suggests this is at least an implicit
congressional declaration that piers are land, and are thus part of
the coastline. However, in an earlier incarnation of this case, we
held to the contrary.
United States v. California, 381
U.S. at
381 U. S.
150-154;
see also Louisiana Boundary Case,
supra, at
394 U. S. 19.
Nothing that has occurred since that ruling indicates that Congress
has withdrawn from the courts the authority to define "coastline."
We have looked to the Convention to give content to the Submerged
Lands Act; no reason is advanced which persuades us to do otherwise
today.
The exception of the State of California to the report of the
Special Master is overruled. The Special Master shall prepare a
proposed form of decree consistent with this opinion and present it
to this Court for entry in due course.
It is so ordered.
MR. JUSTICE MARSHALL took no part in the consideration or
decision of this case.
[
Footnote 1]
The other issues involve the location of the seaward limit of
inland waters at the Port of San Pedro and at the mouth of San
Diego Bay. The parties acquiesce in the Master's conclusion as to
these issues, and anticipate their resolution by agreement.
[
Footnote 2]
These blocks resemble giant versions of a child's "jacks."
[
Footnote 3]
As the Master correctly noted,
"Rincon Island could not qualify as an 'island:' for purposes of
delimiting the territorial sea under the Geneva Convention, because
it is an artificial island."
See Art. 10, Convention on the Territorial Sea and the
Contiguous Zone, Apr. 29, 1958, [1964] 15 U.S.T. 1606, T.I.A.S. No.
5369. For all intents and purposes, then, the island complex is
treated the same as the piers at issue.
[
Footnote 4]
The piers are not unlike fishing piers found in many coastal
areas.
[
Footnote 5]
The Master noted that, though some shipping is handled at some
of the piers, it is insufficient to justify defining them as
"ports." For example, one of them is fitted with a coin-operated
davit for lowering small boats into the water. We agree with this
conclusion. The island, as an island, was disqualified from serving
as a base point for measuring the territorial sea because of its
artificiality.
See n
3,
supra.
[
Footnote 6]
For other discussions on the significance of factual
distinctions and their attendant implications among jetties,
groins, breakwaters, and spoil banks,

Louisiana, 426 U. S. 465,
426 U. S. 469,
and n. 3 (1976);
United States v. Louisiana, 389 U.
S. 155,
389 U. S. 158
(1967).
[
Footnote 7]
In ruling in the
Boundary Case that Louisiana's dredged
channels were not "harbour works," we said:
". . . Article 8 applies only to raised structures. The
discussions of the Article by the 1958 Geneva Conference and the
International Law Commission reveal that the term 'harbour works'
connoted 'structures' and 'installations' which were 'part of the
land,'
and which in some sense enclosed and sheltered the
waters within."
394 U.S. at
394 U. S. 36-37
(emphasis added) .
[
Footnote 8]
California's coastal engineering expert testified that these
piers are designed to have no effect on the movement of the sea. By
contrast, groins and jetties are intended to affect wave
action.
[
Footnote 9]
Even if we were to assume, as did the Master, that "jetties"
means "piers," we would also agree with his conclusion, as we have,
that these piers do not fall within Art. 8, because they are not
part of a harbor or harbor system. But in light of our disposition
it is unnecessary, and we decline, to join the dispute between the
parties over the precise definition of "jetties" as contained in
the English and French versions of the Convention.
