This litigation arose from a vehicular collision which took place at the intersection of Louisiana Highway 84, in Concordia Parish, Louisiana, and the Swayzee Levee Road (the Levee Road).

The only issue on appeal is whether the trial court erred when it granted the Board of Commissioners for the Fifth Louisiana Levy District’s (the Levee District) motion for summary judgment, dismissing it from this litigation. We must determine whether the record reflects the existence of a genuine issue of material fact regarding the Levee District’s duty of garde over the Levee Road. Finding that the Levee Board had no such duty, we affirm.

On December 8, 1999, Mr. Derrick Johnson’s vehicle collided with Mr. John Col-clasure’s while he proceeded “straight” on Highway 84 in Concordia Parish, Louisiana. The accident occurred at the Black *1263River bridge’s eastern foot, within the Highway and the Levee road’s intersection. Allegedly, Mr. Colclasure, attempted to turn left onto Highway 84 from the Levee road when he struck Mr. Johnson’s vehicle.

Mr. Johnson filed suit and named Mr. John Colclasure as a Defendant, as well as his automobile insurer, Southern Farm Bureau Insurance Company (Southern Farm). He sought to recover his resulting injuries and damages. Southern Farm filed a third party demand on March 1, 1999, naming the State of Louisiana, through the Department of Transportation and Development (DOTD), and the Con-cordia Parish Police Jury (the parish) as third party Defendants. On March 26, 1999, Mr. Johnson amended his petition, adding as Defendants, the DOTD, the parish, and Safeway Insurance Company of Louisiana (Safeway), his uninsured/under-insured motorist insurer. Then, on September 20, 1999, again, he amended his petition and added the Levee District as a Defendant. Asserting that it neither had garde, nor responsibility for the intersection, the Levee District filed a motion for summary judgment on March 24, 2000, which the trial court granted on July 25, 2000. DOTD appeals.

Garde

The only issue we must determine on appeal is whether our relevant law, read together with the entire record, reflects the existence of a genuine issue of material fact in dispute regarding the Levee Board’s eventual liability.

Appellate courts review summary judgments de novo under the same criteria that governed the trial court’s consideration of whether or not summary judgment was appropriate.1 Summary judgment is proper when the pleadings, depositions, answers to interrogatories, and admissions on file, together with affidavits show that there is no genuine issue of material fact and that the mover is entitled to a judgment as a matter of law.2

La.Code Civ.P. art. 966, charges the moving party with the burden of proving that summary judgment is appropriate. In doing so, that party’s supporting documentation must be sufficient to establish that no genuine issue of material fact remains to be decided.3 Once the mover makes a prima facie showing that there is no genuine issue as to a material fact and that summary judgment should be granted, the burden shifts to the nonmover.4 Furthermore, La.Code Civ.P. art. 967 provides, in pertinent part:

When a motion for summary judgment is made and supported as provided above, an adverse party may not rest on the mere allegations or denials of his pleadings, but his responses by affidavits or otherwise provided above, must set forth specific facts showing that there is a genuine issue for trial. If he does not so respond, summary judgment, if appropriate, shall be rendered against him.

Un summary, the threshold question in reviewing a trial court’s grant of summary judgment is whether a genuine issue of material fact remains.5 After which, we must determine whether reasonable minds could conclude, based on the facts presented, that the mover is entitled to judgment.6 Thus, summary judgment *1264is apropos when all relevant facts are brought before the court, the relevant facts are undisputed, and the sole remaining issue relates to the legal conclusion to be drawn from the facts.7

Facts are material if they determine the outcome of the legal dispute.8 The determination of the materiality of a particular fact must be made in light of the relevant substantive law.9

The specific issue sub judice is whether the Levee District had garde over a condition which could have been a factor in causing the instant accident. Garde is a word of French terminology which our jurisprudence has interpreted to be a legal obligation imposed on an owner or custodian of a thing to prevent the thing from causing damages to others.10 In Loescher v. Parr,11 our supreme court stated-that “[t]he things in one’s care are those things to which one bears such a relationship as to have the right of direction and control over them and to draw some kind of benefit from them.” However, although ownership, itself, may establish a garde presumption, the owner may rebut such a presumption, and the issue is primarily a question of fact.12

In the instant case, the undisputed facts in the record reveal that the accident occurred on the State’s right-of-way on Highway 84. It is undisputed that, whether ]4by law or fact, the Levee Board exerted no control, dominion, or ownership over the State’s Highway 84 right-of-way. On the contrary, it is, also, undisputed that that responsibility belongs to the DOTD. In fact, La.R.S. 48:259 provides that “[t]he department shall maintain the highways forming the state highway systemf.]” (Emphasis added.)

Additionally, La.R.S. 38:306(A) specifies the Levee Board’s duties as follows:

Each board of commissioners may buy and hold, sell and transfer, or exchange property, make and execute contracts, and do and perform any and all acts necessary to insure the thorough and adequate protection of the lands of the district from damage by flood, and, in the case of levee and drainage boards, for the adequate drainage control of the district.

(Emphasis added.)

Although Levee Boards may exert garde over levee roads which are closed to the public,13 the record sub judice further reflects that the Levee Road is open to the public and is included in Concordia Parish road’s list. Additionally, the unrebutted evidence in the record, adduced through depositions, reveals that Concordia Parish did, in fact, maintain and place traffic signals on the Levee Road, including its intersection with Highway 84.

Finally, in his February 2, 2000 deposition, Mr. Reynold S. Minski, President of the Louisiana Fifth Levee District which has jurisdiction over the instant levee, explained the levee’s existence in connection to the Levee Road, as follows:

We don’t have any reason to want to move [the levee]. I mean, someone else would have had to ask to move it, because we — As I said earlier, this particular part of the road, as far as we are concerned. Could be completely shut off. It doesn’t have any — It doesn’t play any part in what we — you know, to maintain [sic] the levee. We don’t have to have that road.

Viewing Mr. Minsky’s deposition in the context of the other evidence adduced in the record, it is clear that the Levee Board *1265did not draw any benefit from having the Levee Road open to the public.

| [¡After conducting a de novo review of the record, we find that DOTD simply failed to introduce any genuine issue of material facts regarding the Levee Board’s duty of garde over the Levee Road, specifically as it intersects with Highway 84. Accordingly, we affirm the trial court’s summary judgment.

CONCLUSION

After conducting a de novo review of the record, we find that DOTD did not show the existence of a genuine issue of material fact regarding the Levee Board’s liability concerning the instant traffic accident. Accordingly, we affirm the trial court’s summary judgment and cast DOTD with costs.

AFFIRMED.
