Gary R. Barnes appeals the district court’s 1 adverse grant of summary judgment in his suit against his former employer, the City of Coon Rapids, Minnesota, alleging negligence and violations of the Americans with Disabilities Act, 42 U.S.C. § 12101, et seq. (ADA). On appeal, he also asserts a retaliation claim. After carefully reviewing de novo the grant of summary judgment on Barnes’s ADA claims, see Johnson v. Blaukat, 453 F.3d 1108, 1112 (8th Cir. 2006), we find no basis for reversal. We decline to consider either Barnes’s negligence claim, which he does not address on appeal, see Griffith v. City of Des Moines, 387 F.3d 733, 739 (8th Cir. 2004) (claims not briefed on appeal are deemed abandoned), or his retaliation claim, which he presents for the first time on appeal, see Stone v. Harry, 364 F.3d 912, 914 (8th Cir. 2004).

Accordingly, the judgment of the district court is affirmed. See 8th Cir. R. 47B.
