OPINION
¶ 1 The City of Tucson appeals a summary judgment in favor of Clear Channel Outdoor, Inc., in the City’s action seeking to enforce its ordinances against nonconforming billboard structures. The City argues the trial court erred in retroactively applying the two-year statute of limitations in A.R.S. § 9-462.02(C) to bar the majority of its enforcement claims against Clear Channel for violating the City’s sign and zoning codes. For the reasons set forth below, we affirm.
Facts and Procedural History
¶2 On appeal, we view the facts and all reasonable inferences in the light most favorable to the City, the party against whom the summary judgment was granted.
See Walk v. Ring,
*337 ¶3 The City conceded it had discovered many of the violations more than two years before filing its complaint, but argued, inter alia, that the legislature did not intend that the newly created statute of limitations apply retroactively and that § 9^62.02(C) is subject to the provisions of A.R.S. § 12-505 and case law limiting the retroactive application of statutes of limitations. In support of its arguments, the City proffered minutes of the State Senate Finance Committee hearing on the bill that became § 9-462.02(0), a lobbyist’s statement, and letters from the State Senate Rules Office and Eller’s chief executive officer expressly stating the bill would not have retroactive application. The trial court rejected the City’s evidence and granted Clear Channel’s motion on 89 of the 173 alleged violations, finding that the statute applied retroactively and barred the City’s enforcement action on the violations the City had discovered more than two years before it filed its complaint. This appeal followed.
Retroactive Application of § 9^462.02(C)
¶ 4 The City first argues that the two-year limitations period in § 9-462.02(C) “must be applied prospectively to avoid an unconstitutional result” and that barring its existing claims under a newly enacted statute of limitations violates both the United States and Arizona Constitutions.

The City cites
Crowell v. Davenport,
¶ 5 As a general rule, a statute does not apply retroactively unless the legislature so specified, A.R.S. § 1-244, but “statutes [concerning] procedures and remedies that do not impair vested rights are exceptions.”
City of Tucson v. Whiteco Metrocom, Inc.,
¶ 6 The City attempts to distinguish
Whiteco
by pointing to its holding that the statutory modification or elimination of a city’s substantive zoning authority during the pendency of an enforcement action could eliminate that cause of action, noting this case involves a statute of limitations, not the repeal of substantive zoning authority. But this is a distinction without a difference. The City’s zoning authority, as well as its authoi’ity to enforce its zoning ordinances, derives exclusively from the state.
Outdoor Systems, Inc. v. City of Mesa,
¶7 In deciding whether a newly enacted statute of limitations could absolutely bar a government claim in an analogous case, the Supreme Court stated that “no constitutional question is raised by applying [the new statute] to pre-existing claims of the Government.”
United States v. Lindsay,
Statutory Interpretation
¶ 8 The City further argues that, “when new legislation is silent on the issue of retroactive application, A.R.S. § 12-505 becomes the sole expression of legislative intent.” Subsection B of that statute, which the City contends is controlling, states, “If an action is not barred by pre-existing law, the time fixed in an amendment of such law shall govern the limitation of the action.” The City challenges the trial court’s conclusion that the “time fixed” began on the date of discovery of the violations, asserting it instead began on the effective date of § 9-462.02(C) without the “attached conditions such as knowledge or discovery” that the statute specifies. But we assume the legislature intended that the words in a statute be given natural and obvious meanings unless otherwise stated.
State v. Jones,
¶ 9 The City nevertheless points to language in
Rutherford v. Babcock,
¶ 10 The City further contends that the trial court erred in failing to consider several “critical documents that established the legislative history and evidence of legislative intent in enacting A.R.S. § 9^462.02(C).” Interpretation and application of a statute is a question of law we review de novo, primarily focusing on legislative intent.
Moore v. Browning,
¶ 11 At oral argument, the City asserted, contrary to suggestions and statements in its briefs on appeal, that there is no ambiguity or lack of clarity in § 9-462.02(0 that requires resorting to rules of statutory interpretation. We agree. As discussed earlier, statutory changes in procedures or remedies may be retroactively applied to proceedings already pending except when the legislature has stated otherwise or vested rights would be impaired. As also noted, the City had no vested rights in enforcing its zoning and sign codes. See
Whiteco; Wilco Aviation.
And, if the legislature had intended the new statute of limitations to have only prospective application, it could have so specified or otherwise indicated that any preexisting claims were preserved. In the absence of any ambiguity, courts must apply the statute’s language without resort to legislative intent.
See Viramontes; Hayes v. Continental Ins. Co.,
Public Policy on Elimination of Nonconforming Uses
¶ 12 Lastly, the City advances the “judicial” policy, enunciated in
Outdoor Systems and Rotter v. Coconino County,
Disposition
¶ 13 The judgment in favor of Clear Channel is affirmed. Clear Channel is entitled to fees on appeal pursuant to A.R.S. § 12-348(A), and its request for them is granted upon compliance with Rule 21(c), Ariz. R. Civ.App. P., 17B A.R.S.
Notes
. The defendant billboard owner changed from Eller to Clear Channel during this litigation.
. Because the legislature adjourned on April 18, 2000, § 9-462.02(C) and other nonemergency legislation became operative ninety days later. See Ariz. Const, art. IV, pt. 1, § 1(3).
. The city did not reurge this argument in its reply brief or at oral argument.
. In pertinent part, § 9-462.05(A) states, "The legislative body of a municipality has authority to *338 enforce any zoning ordinance enacted pursuant to this article.”
. Section 12-505(C) provides: "If an amendment of pre-existing law shortens the time of limitation fixed in the pre-existing law so that an action under pre-existing law would be barred when the amendment takes effect, such action may be brought within one year from the time the new law takes effect, and not afterward." That subsection does not apply, however, when "an action is not barred by pre-existing law," § 12-505(B), and both the City and Clear Channel agree that § 12-505(B) is the operative provision here.
. We find misplaced the City’s reliance on
