MEMORANDUM ***

Plaintiff Pedro Arroyo appeals from the district court’s decision on cross-motions for summary judgment in this insurance coverage dispute. The district court granted summary judgment in favor of Defendant Unigard Insurance Company on the ground that Unigard did not owe a duty to defend its insured, Jack Neal & Sons, Inc. and Jack Neal (collectively, “JNS”), in Arroyo’s previous state court action alleging that JNS’s improper development and management of his vineyard caused property damage. We hold that Unigard did not owe a duty to defend JNS in Arroyo’s state court action and, therefore, is not liable to Arroyo.

1. We have jurisdiction under 28 U.S.C. § 1291. A district court’s decision on cross-motions for summary judgment is reviewed de novo. See Guatay Christian Fellowship v. Cty. of San Diego, 670 F.3d 957, 970 (9th Cir. 2011). Under California law, an insurer must provide a defense for its insured against any “suit which potentially seeks damages within the coverage of the policy.” Horace Mann Ins. Co. v. Barbara B., 4 Cal.4th 1076, 17 Cal.Rptr.2d 210, 846 P.2d 792, 795 (1993) (internal quotation marks omitted). Once it appears that claims against the insured create a potential for indemnity, the insurer’s defense duty will continue “until it has been shown that there is no potential for coverage.” Montrose Chem. Corp. of Cal. v. Superior Court, 6 Cal.4th 287, 24 Cal.Rptr.2d 467, 861 P.2d 1153, 1157 (1993). In other words, “the insurer must prove [the underlying claims] cannot” fall within the policy coverage in order to be relieved of its duty to defend. Id. at 1161.

Here, the district court properly concluded that Exclusion J(5) of Unigard’s insurance policy issued to JNS precluded coverage of Arroyo’s state-court claims. Exclusion J(5) specifically states that Uni-gard’s policy does not cover “property damage” to “[t]hat particular part of real property on which you ... are performing operations, if the ‘property damage’ arises out of those operations.” The district court properly construed “that particular part of real property” to cover Arroyo’s entire vineyard that JNS was hired to develop and manage. The district court also properly concluded that “are performing operations” does not exclude only property dam *883 age that developed simultaneously as the work was being performed, but also property damage that clearly flows from the insured’s work on the property. Because all of Arroyo’s property damage alleged in his state court action arose out of JNS’s operations, Exclusion J(5) relieved Uni-gard of its duty to defend JNS and, therefore, Unigard is not liable to Arroyo.

AFFIRMED.
