Appellant Theodore Fleischmann appeals the judgment entered October 4, 1994, by G. Marvin Bober, Associate Chief Administrative Law Judge (“ALJ Bober”), denying his application for benefits. Fleischmann was injured while repairing a washed-out bulkhead in a canal. ALJ Bober held that Fleischmann was not entitled to coverage under the Longshore and Harbor Workers’ Compensation Act (“LHWCA”), 33 U.S.C. §§ 901-950 (1994), because he was not injured on navigable waters, and because he did not qualify as an “employee” within the meaning of § 902(3). We reverse and remand, finding that Fleischmann meets the LHWCA’s standards.both as to his status as an employee and as to the situs of his injury.
Reversed and remanded.
I.
Facts
The parties do not dispute the following facts. Petitioner Theodore Fleischmann was employed in 1991 by Respondent Seahorse Coastal Assistance & Towing (“Seahorse”) as a pile driver and a laborer. Fleischmann worked on constructing bulkheads, piers, and floating docks. In October of 1991, Fleisch-mann was helping to remove and replace a bulkhead at Center Island, on a canal off Oyster Bay leading to the northern shore of Long Island Sound. While ordinarily a bulkhead, which acts as a retaining wall for land, must border land on one side and water on the other, a large part of this bulkhead had collapsed forward into the water when the land behind had washed into the canal in a series of storms. A private residence abutted the area where the bulkhead had collapsed.. The water contained a floating dock belonging to the property owner, to which a boat belonging to the owner’s employee was tied. The completed bulkhead would prevent erosion of the land into the water.
Seahorse built the new bulkhead by driving piles deep into the bed of the canal, and attaching a horizontal retaining system to those piles. At the time of Fleischmann’s accident, twelve to fifteen feet of water and muck still separated the solid land of this residence from the bulkhead. The repaired bulkhead was attached to the land at both ends, but pores in the bulkhead wall permitted water to seep behind it.
To complete construction of the bulkhead, Fleischmann helped to move material from the canal bottom to fill in the area landward of the bulkhead. Seahorse used material from the bottom of the canal as filler, to save money on material and transportation, and to deepen the water in the canal, Fleischmann and other Seahorse workers had nearly completed the process of moving dredging material behind the bulkhead at the time of Fleischmann’s accident.
While repairing the bulkhead, Fleischmann worked primarily on a floating dock, which was tied to a barge. The equipment used to repair the bulkhead was floated to the job site on a barge belonging to Seahorse, and Fleischmann testified that he had helped to tie and untie the work boats that moved the barge there.
On October 22, 1991, Fleischmann was cleaning up the barge and removing lumber from the floating dock. At the time of his accident, he was on top of the bulkhead and moving the barge by pulling on a tow line. As Fleischmann reached for a second tow line, he slipped on the top of the bulkhead and fell over the landward side. His foot caught on the bulkhead, and he fell into the dredging material and water. Although Fleischmann got wet when he fell, his trapped boot kept him from going under the water completely. At the time Fleischmann fell, the tide was such that there was enough *134 water behind the bulkhead to cover his body. At the point where he fell, he was approximately fifteen feet from solid land.
II.
The ALJ’s Decision
Fleischmann sustained injuries to his right knee from the fall and applied for benefits under the LHWCA At his hearing, the parties stipulated that Fleischmann was “deemed to be temporary totally disabled from the date of accident.” His petition was heard by Administrative Law Judge (“ALJ”), Aaron Silverman, who retired prior to deciding the ease. ALJ G. Marvin Bober was assigned to the matter and rendered a decision solely on the written record.
Section 920(a) of the LHWCA grants a presumption of coverage, which applies unless the employer presents substantial evidence to rebut the presumption. 33 U.S.C. § 920(a) (1994). ALJ Bober held that the § 920(a) presumption did not apply to questions of situs or. status, and, thus, that Fleischmann had the burden of proving facts establishing his coverage under the Act.
ALJ Bober noted that to establish coverage under the LHWCA, Fleischmann had to establish both that he had status as an “employee” under § 902(3) and that the injury occurred on a situs covered under § 903(a). ALJ Bober also noted that if Fleischmann could show that he were injured on “navigable waters,” as defined before the 1972 amendments to the LHWCA, he would be covered, without any further showing regarding his employee status, because the 1972 amendments were designed to expand, not to limit, coverage. ALJ Bober found that although the canal itself constituted navigable waters, Fleischmann was not injured on actual navigable waters as defined before 1972, because water in the area where Fleisch-mann fell had been permanently withdrawn from the canal. ALJ Bober went on to find that Fleischmann lacked status as an “employee” within the meaning of § 902(3).
The Claimant’s job was not related to the movement of cargo between ship and land transportation, nor did it serve to facilitate these functions. Several Supreme Court decisions addressing Section 2(3) have “clearly decided that, aside from the specified occupations, land-based activity occurring within the § 903 situs will be deemed maritime only if it is an integral or essential part of loading or unloading a vessel.” As the Claimant’s employment did not entail such duties, it is not encompassed within the coverage afforded by Section 2(3).
He therefore made no ruling on the question whether Fleischmann’s accident occurred upon a covered situs, as defined under the amended LHWCA.
Fleischmann appealed to the Benefits Review Board (“BRB”), and the Office of the Solicitor filed an amicus letter in his support. Because the BRB failed to render a decision within one year, the ALJ’s decision was deemed affirmed. See Omnibus Consolidated Rescission and Appropriations Act of 1996, Pub.L. No. 104-134, 110 Stat. 1321, 1321-219 (1996). Fleischmann now brings direct appeal to our court, under § 921(c) of the LHWCA
III.
Discussion
A. Standard of Review
The BRB hears appeals from decisions made by an ALJ under the LHWCA. 33 U.S.C. § 921(b)(3) (1994). The BRB must apply a narrow standard of review to those decisions and is required to affirm the ALJ’s findings of fact as long as they are supported by substantial evidence in the record considered as a whole.
Id.; see also King v. Director, Office of Workers’ Comp. Programs,
*135 Although we agree with Fleischmann that the ALJ erred by failing to apply the § 920(a) presumption of coverage to questions of fact and by placing the burden of production of evidence on Fleischmann, this error does not affect our ruling. Because we base our ruling on essentially undisputed facts of record, addressing legal issues only, we would reach the same conclusion even if we determined that the presumption did not apply.
B. Coverage Under the LHWCA
Before 1972, the LHWCA covered only employees who were injured on actual navigable waters; the LHWCA did not cover employees injured on land, or on structures connected to land, no matter how close to the water the injury occurred.
See Nacirema Operating Co. v. Johnson,
Because Congress intended the 1972 amendments to expand the scope of coverage, an employee can still establish coverage by demonstrating that he or she satisfies the situs test as it existed before it was expanded by the 1972 amendments, without having to make any farther showing regarding status as an employee under § 902(3).
See Director, Office of Workers’ Comp. Programs, U.S. Dep’t of Labor v. Perini N. River Assocs.,
1. Status
ALJ Bober decided that Fleischmann did not qualify as an employee under § 902(3) because “his job was not related to the movement of cargo between ship and land transportation, nor did it serve -to facilitate these functions.” He relied on
Chesapeake and Ohio Railway v. Schwalb,
which held that “aside from the specified occupations, land-based activity occurring within the § 903 situs will be deemed maritime only if it is an integral or essential part of loading or unloading a vessel.”
Schwalb,
The Director urges that Fleisehmann, a marine construction worker, qualifies as a “harbor worker,” one of the occupations specifically listed in § 902(3). While we owe no deference to the BRB, we do grant deference to the views of the Director of the Office of Workers’ Compensation Programs, a Respondent in this case, with regard to questions of interpretation of the LHWCA
See Director, Office of Workers’ Comp. Programs, U.S. Dep’t of Labor v. General Dynamics Corp.,
The Director’s interpretation of the term “harbor worker” to include marine construction workers should be accorded deference because the term “harbor worker” is undefined and ambiguous, and because including marine construction workers within the meaning of “harbor worker” is reasonable and preserves the purposes of the statute. Generally, the Court has adjudged that “[t]he language of the 1972 Amendments is broad and suggests that we should take an expansive view of the extended coverage.”
Caputo,
Our finding that Fleisehmann qualifies as a harbor worker also comports with the Supreme Court’s and this circuit’s reading of the requirements of § 902(3). ALJ Bober made a factual finding that Fleischmann’s general employment responsibilities included “building bulkheads, piers, and floating docks.” An employee can establish coverage under § 902(3) either by referring to his or her overall duties or to the particular project the employee was engaged in at the time of injury.
See Caputo,
The Second Circuit has determined that the category of “harbor worker” under § 902(3) requires some connection to ships.
See Fusco v. Perini N. River Assocs.,
The reasonableness of categorizing Fleisehmann as a harbor worker is supported by consistent decisions of the BRB involving marine construction workers. While the BRB, as opposed to the Director, does not merit deference,
see General Dynamics Corp.,
2. Situs
Under the 1972 amendments, a situs covered by the LHWCA includes navigable waters and “any adjoining pier, wharf, dry dock, terminal, building way, marine railway, or other adjoining area customarily used by an employer in loading, unloading, repairing, dismantling, or building a vessel.” 33 U.S.C. § 903(a). In reading this section, the Supreme Court has noted that “it is not at all clear that the phrase ‘customarily used’ was intended to modify more than the immediately preceding phrase ‘other areas.’.!’
Caputo,
The Ninth Circuit in
Hurston
articulated a strictly structural definition of the term “pier”: “a structure built on pilings extending from land to navigable water is an ‘adjoining pier’ within the meaning of 33 U.S.C. § 903(a).”
Id.
at 1553. It employed this definition to determine that a structure used only for storing and processing oil did constitute a pier for the purposes of § 903(a). Although the dissent in
Hurston
characterized the definition as “a literal interpretation,”
id.
at 1554, and although the structure at issue in that case was called “Elwood Pier No. 1,” the decision did not depend solely on the structure’s nomenclature. Instead, the court focused primarily on the intent of Congress in amending the LHWCA.
Id.
at 1550-1553. The court noted that Congress’s failure to define “pier” suggests that Congress intended to “leave the geographic areas
*139
such as a pier or wharf unlimited so long as they adjoin navigable waters of the United States.”
Id.
at 1551. The court guided itself by the ameliorative purpose of the 1972 amendments: “the 1972 amendments were intended to ‘provide[ ] continuous coverage to a worker who would otherwise be covered for only a part of his activity’ and ... [to] alleviate[ ] the anomaly of a longshoreman’s walking in and out of coverage depending on which side of the gang plank an injury occurred.”
Id.
at 1552 (quoting
Williams v. Director, Office of Workers Comp. Programs,
We adopt the majority’s reasoning in
Hurston.
The bulkhead at issue, built on pilings and extending into navigable water, constitutes a pier within the meaning of § 903(a). That the bulkhead is not called a pier does not affect our determination. This case exemplifies the concerns that fueled the 1972 amendments; Fleischmann would clearly have been covered had he been injured while working on a work platform only several feet away, where he spent a substantial portion of his work hours. Although the line demarking a covered situs has to be drawn somewhere, Congress made it clear in enacting the 1972 amendments that it considered the water’s edge an arbitrary place to draw it. Congress did not want a system in which coverage depend[ed] on the “fortuitous circumstance of whether the injury ... occurred on land or over water.”
Caputo,
The BRB has also focused on the physical composition of shore-side structures and has allowed a range of structures to qualify as piers within the meaning of § 903(a). In doing so the BRB has found structures not ordinarily referred to as “piers” nevertheless to qualify as such under the statute. In
Olson,
the BRB found that a breakwater, located in an area containing a dock, constituted a “pier,” considering that it helped to form and protect a harbor.
Olson,
Conclusion
For the above reasons, we reverse and remand to the Benefits Review Board for determination of benefits.
Notes
. Fleischmann argues that we ought to apply a more stringent standard of review to ALJ Bober’s Decision and Order because AU Bober was not the actual trier of fact for purposes of the hear *135 ings; ALJ Silverman presided during that stage of the proceedings. However, we do not need to decide whether to apply a more stringent standard of review to findings of fact in this case, since we base our decision on facts that are undisputed in all salient respects.
. Seahorse argues that we should not accord deference in this case because the Director’s interpretation tends to expand the scope of coverage of the LHWCA. Beqause deference to administrative agencies is based on a congressional delegation of interpretive authority, Seahorse argues it is unlikely that Congress would delegate authority to an agency to determine its own jurisdictional reach. See Cass A. Sunstein, Law and Administration After Chevron, 90 Colum. L.Rev. 2071, 2097-2100 (1990). However, the Supreme Court has deferred to agency interpretations that arguably determine jurisdiction, and there appears to be no clear test for whether an interpretation should be considered "jurisdictional.” See id. at 2098-2099 & nn. 126 & 132-133. The issue here, the meaning of "harbor worker” within § 902(3), while arguably jurisdictional, does not evoke the concerns that would make it unlikely that Congress delegated authority to the agency for its determination. The agency does not seek to extend its authority to a large category of cases, nor to abdicate its enforcement power, and the expertise of the Director is relevant to the determination. See id. at 2100 ("[A] general rule of deference would be preferable even on jurisdictional questions,____ [where] the agency’s competence bears on the resolution of jurisdictional ambiguities____ [T]he question is whether the agency is seeking to extend its legal power to an entire category of cases, rather than disposing of certain cases in a certain way or acting in one or a few cases.”).
. Furthermore, it is not disputed that at the time of his injury Fleisehmann had been assisting Seahorse in the process of filling in the area behind the bulkhead with material dredged from the bottom of the canal; Seahorse’s president testified that, aside from financial considerations, the reason Seahorse dredged the bottom of the canal was to deepen the water, which would have the effect of increasing navigability. In addition, Seahorse did not dispute Fleischmann’s testimony that when transporting Seahorse’s equipment to the site of the bulkhead, Fleisch-mann rode upon a barge and engaged in the process of lying and untying the vessels used to transport it.
See Silva v. Hydro-Dredge Corp.,
. We wish to emphasize that we do not base our holding that Fleischmann has occupational status on any version of the test first articulated by the Ninth Circuit in
Weyerhaeuser Co.
