Opinion by
Plaintiff, Grandote Golf and Country Club, LLC (Grandote), appeals the district court's judgment granting defendant Town of La Veta's motion to dismiss. We affirm.
I. Background
In 1984, the Town adopted Ordinance No. 131 to annex certain property in Huerfano County after Grandote's predecessor in interest, Grandote Golf and Country Club (GGCC), the owner of the property, petitioned it to do so. In 1985, GGCC filed a court action seeking to require the Town to *1198 file two certified copies of the ordinance with the county clerk and recorder (the Town had filed only one), claiming that such filing was statutorily required to render the annexation effective. In exchange for GGCC dismissing the lawsuit, the Town adopted Ordinance No. 144 to repeal Ordinance No. 131. In 1987, the Town adopted Ordinance No. 154 to annex a portion of the property after GGCC petitioned it to do so.
In 2009, Grandote filed this action, seeking a declaratory judgment that Ordinance No. 144 was void and of no effect because the Town had not complied with statutory disconnection requirements, and therefore all the property Ordinance No. 181 purported to annex remained part of the Town 1 The Town filed a motion to dismiss, arguing that two statutes of limitation barred Grandote's complaint. In later briefing, the Town also asserted that Ordinance No. 181's purported annexation never took effect because two statutorily required filings had not been made, and therefore Ordinance No. 144 did not have to comply with the disconnection statutes because there was no annexed property to disconnect. Specifically, the Town asserted that it had not filed a second certified copy of Ordinance No. 181 with the county clerk and recorder, as required by a former - version - of - section _ 831-12-118(2)(a)(ID)(A), C.R.S.2010, and by 24-82-109, C.R.S.2010, and that the county clerk and recorder had not filed a copy of Ordinance No. 181 with the division of local government, as required by section 24-32-109 2 The Town asserted in the alternative that the property described in Ordinance No. 181 was no longer in the Town because GGCC, the Town, and the Board of County Commissioners would not have respectively petitioned for, adopted, and approved Ordinance No. 154 had they considered the property already within the Town.
The district court granted the Town's motion to dismiss, concluding that Grandote's declaratory judgment action accrued on Ordinance No. 144's effective date in 1985 and was, therefore, barred by the applicable two-year statute of limitations. Ruling in the alternative, the court concluded that Gran-dote was not entitled to declaratory relief because Ordinance No. 144 had repealed Ordinance No. 131, and GGCC's subsequent petition for and the Town's subsequent adoption of Ordinance No. 154 indicated that both GGCC and the Town understood the property was not in the Town.
Grandote appeals, contending that (1) the statute of limitations for its declaratory judgment action (a) never began to run because Ordinance No. 144 never became effective or, (b) began to run only when Grandote knew or should have known that Ordinance No. 144 was not effective; (2) the district court should not have considered GGCC's and the Town's subjective understanding of Ordinance No. 144's validity in determining whether that ordinance was effective; and (3) Ordinance No. 144 is invalid because the Town did not comply with statutory disconnection requirements.

All these contentions are moot, however, if the annexation contemplated by Ordinance No. 131 never became effective, a matter which, though raised by the Town, the district court did not address. We conclude that it did not become effective; therefore, Ordinance No. 144 repealed Ordinance No. 131 and did not need to comply with statutory disconnection requirements. See Newflower Mkt., Inc. v. Cook,
*1199 II. Standard of Review
The Town did not submit exhibits with its initial, statutes of limitation-based motion to dismiss. However, it subsequently submitted multiple exhibits to demonstrate that Ordinance No. 1381's purported annexation of the property never became effective because (1) it had filed only one of the two certified copies of Ordinance No. 1831 that sections 31-12-118@)(a)(ID)(A) and 24-32-109 required it to file with the county clerk and recorder; and (2) the county clerk and recorder had not filed a copy of the ordinance with the division of local government as required by section 24-32-109. Both parties assume that the district court considered these documents and that the Town's motion to dismiss was thereby converted to a motion for summary judgment, and urge us to apply summary judgment principles to Grandote's appellate contentions. Therefore, we agree that review applying such principles is appropriate. See C.R.C.P. 12(b) (if matters outside the pleadings are presented to and not excluded by the district court, a motion to dismiss for failure to state a claim shall be treated as one for summary judgment); Pub. Serv. Co. v. Van Wyk,
Summary judgment is appropriate if the pleadings and supporting documentation demonstrate that no genuine issue of material fact exists and that the moving party is entitled to summary judgment as a matter of law. Rocky Mountain Festivals, Inc. v. Parsons Corp.,
TIL Discussion
Grandote does not dispute that the two statutorily required filings of Ordinance No. 131 were not made. Instead, Grandote contends that we must presume Ordinance No. 131's purported annexation was effective because the Town never instituted court proceedings to have the ordinance declared invalid. In the alternative, Grandote contends that Ordinance No. 131 validly annexed the subject property because there was substantial compliance with the statutory filing requirements. We are not persuaded by either contention.
A. The Town May Challenge the Effectiveness of Ordinance No. 131
As a threshold matter, we disagree with Grandote's argument that we cannot consider the alleged ineffectiveness of Ordinance No. 1831's purported annexation because the Town never sought a declaratory judgment that Ordinance No. 131 was ineffective.
Grandote's complaint challenged whether Ordinance No. 144 effectively disconnected the property Ordinance No. 181 had purported to annex. Grandote thereby placed the effectiveness of Ordinance No. 1831's annexation in issue because the disconnection statutes on which Grandote relies applied to Ordinance No. 144 only if Ordinance No. 131 effectively annexed the property-that is, if the property at issue was "within and adjacent to" the Town or part of "an existing municipality." See §§ 31-12-501, 24-32-109. Therefore, we may address whether Ordinance No. 181 effectively annexed the property. See 7250 Corp. v. Bd. of County Comm'rs,
*1200 B. The Annexation Contemplated by Ordinance No. 131 Was Never Effective
It is undisputed that two certified copies of Ordinance No. 181 (together with a map of the annexed property) were not filed with the county clerk and recorder as required by sections 81-12-118(2)(a)(II)(A) and 24-82-109. Nor is it disputed that the county clerk and recorder never filed a copy of the ordinance (again, with a map of the annexed property) with the division of local government, as required by section 24-32-109. But Grandote argues that Ordinance No. 1831's annexation was effective because there was substantial compliance with the statutory filing requirements. We conclude that substantial compliance is insufficient to satisfy these statutory requirements and, even if it were, there was no substantial compliance with section 24-82-109's requirement that the ordinance be filed with the division of local government.
Whether the filing requirements of see-tions 31-12-118(2)(a)(ID(A) and 24-82-109 must be strictly complied with or need only be substantially complied with to render an annexation effective is an issue of first impression in Colorado. The issue is one of statutory interpretation. See Charnes v. Norwest Leasing, Inc.,
In 1984, when the Town enacted Ordinance No. 131, section 81-12-1183 provided in relevant part as follows:
(1) If the conditions of subsection (2) of this section are met, area annexed to a municipality ... shall be annexed upon the effective date of the annexing ordinance....
(2)(a) The annexing authority shall:
[[Image here]]
(ID(A) File for recording two certified copies of the annexation ordinance and map of the area annexed containing a legal description of such area with the county clerk and recorder of each county affected.
[[Image here]]
(b) No annexation shall be effective until the requirements of sub-subparagraph (A) of subparagraph (II) of paragraph (a) of this subsection (2) are met.
Ch. 275, see. 1, § 81-12-1181), (2)(b), 1975 Colo. Sess. Laws 1086. 5 Section 31-12-113(2)(c) provided, however, that "[in any action attacking the validity of an annexation proceeding, failure of the annexing municipality to have made the filings required by [subsection 31-12-118(2)] shall not be deemed to invalidate the annexation where good cause for such failure is shown."
Section 24-32-109 provides in relevant part, as it did in 1984, that "[nlo annexation . shall be effective until notice of the completion of such action with a legal description accompanied by a map of the area concerned is filed in duplicate by the municipality with the county clerk and recorder of the county in which the annexation ... takes place." It goes on to state: "[a] certified duplicate copy of any annexation ... shall be filed with the division of local government by the county clerk and recorder of the county." 6
Reading these two statutes together, it is clear that the county clerk is responsible for filing with the division of local government one of the certified copies of the annexation *1201 ordinance and map that the municipality must file with the clerk. 7
There are several clear indications in these statutes that substantial compliance with the filing requirements is insufficient.
First, both statutes plainly declare that the consequence of noncompliance is that the annexation shall not become effective. See §§ 31-12-113(1), (2)(b), 24-82-109. This indicates an intent to require strict compliance with the filing requirements. See In re Marriage of Slowinski,
Second, unlike the statute governing petitions for annexation, sections 81-12-113 and 24-32-109 do not now and did not in 1984 expressly allow for substantial compliance. Compare § 31-12-118(2), and § 24-82-109, with § 81-12-107(1)(g), C.R.S.2010 ("If the petition is found to be in substantial compliance with this subsection [further annexation proceedings shall commence."). Because these statutes pertain to the same subject, this omission indicates that the General Assembly intended that only strict compliance would satisfy the filing statutes. See Sinclair Mktg. Inc. v. City of Commerce City, 226 P.Bd 1239, 1243 (Colo.App.2009) (the omission of a provision in one statute that is included in another similar statute suggests the omission was intentional); Deutsch v. Kalceviec,
Third, the presence of an explicit good cause exception in subsection 81-12-118(2)(c) suggests that the General Assembly intended that only a showing of good cause would excuse strict compliance with that statute. See In re Marriage of Chalat,
Therefore, we conclude that the filing requirements of sections 81-12-118(2)(a)(IID)(A) and 24-32-109 may not be satisfied by mere substantial compliance. See Johnston v. City Council,
Accordingly, because the required filings of Ordinance No. 181 did not oceur, and because no good cause was shown (or even alleged) for the failure, the annexation contemplated by Ordinance No. 181 did not become effective. 9
We are not persuaded otherwise by Gran-dote's reliance on Board of County Commissioners v. City of Aurora,
Further, complying with section 81-12-108.5 required the municipality to use its judgment to determine what was "in the vicinity of" the area to be annexed, to create a plan for services in the area, and to otherwise describe the area proposed to be annexed. See § 81-12-108.5; City of Aurora,
Alternatively, even if we assume that substantial compliance with sections 31-12-113 and 24-32-109 may render an annexation *1203 effective, we conclude that here there was not substantial compliance with section 24-32-109's requirement that a certified copy of the ordinance (and map) be filed with the division of local government. 10
To determine whether there has been substantial compliance with a statute, we consider whether the allegedly complying acts fulfilled the statute's purpose. See Meyer v. Lamm,
The General Assembly created the division of local government for several reasons, including to "provid[e]l coordination of state services and information to assist local government in effectively meeting the needs of Colorado citizens." $ 24-82-101(1)(d), C.R.S. 2010. The division fulfills this purpose, in part, by recording all changes to municipal boundaries and maintaining maps of all municipalities as public records. See § 24-32-108, C.R.S.2010. Section 24-82-109's3 requirement that a certified copy of every annexation ordinance be filed with the division of local government therefore enables the division to maintain accurate information about municipal boundaries as required by section 24-82-108. Thus, that requirement cannot be deemed a mere formality: exeus-ing noncompliance with the requirement would not result in fulfillment of the relevant statutes' purposes. See Meyer,
Because we conclude that, under the undisputed facts, Ordinance No. 1831's purported annexation did not become effective as a matter of law, we affirm the district court's judgment.
Judgment affirmed.
Notes
. In Grandote's view, Ordinance No. 154 was of no effect because the property it purported to annex (and more) had already been annexed. Grandote does not challenge the validity or effec-liveness of Ordinance No. 154 on any other basis.
. This latter requirement also appears in section 31-12-113(2)(a)(II)(B), C.R.S.2010.
. Section 31-12-501, C.R.$.2010, provides (as it did in 1985) certain requirements to disconnect "a tract of land within and adjacent to the boundary of a city or town. ..." A "detachment of any area ... of an existing municipality" must also comply with the requirements of section 24-32-109.
. Though Grandote alleges that the county has taxed its property as if all of it is within the Town, it does not contend that the Town is thereby estopped to assert that the annexation contemplated by Ordinance No. 131 was never effective. Therefore, we do not address that issue.
. Section 31-12-113(2)(a)(II)(A) was amended in 2000 to require the filing for recording of three certified copies of the annexation ordinance and map with the county clerk and recorder. Ch. 120, see. 2, § 31-12-113(2)(a)(II)(A), 2000 Colo. Sess. Laws 422. Otherwise, the current version is substantially identical to the version in effect at the time of the events at issue.
. Section 24-32-109 has not been amended in any respect since 1975.
. This intent is further borne out by the 2000 amendment to section 31-12-113(2)(a)(II)(8) requiring the municipality to file three certified copies of the annexation ordinance and map with the county clerk. That amendment was made in conjunction with another requiring the clerk to file one of the certified copies with the department of revenue. Ch. 120, sec. 2, § 31-12-113(2)(a)(II)(B), 2000 Colo. Sess. Laws 422.
. Grandote has never alleged that there was any good cause here.
. To the extent Grandote suggests that Ordinance No. 131's purported annexation was effective either because the Town would not have enacted Ordinance No. 144 had it believed that the annexation was ineffective, or because Ordinance No. 144 purported to "disconnect" the property, we note that an ineffective annexation cannot be made effective simply by later reliance on or an assumption of its effectiveness. See Johnston,
. Grandote argues that there was substantial compliance with section 31-12-113(2)(a)(ID(A) because one of the two required certified copies was filed. But Grandote does not argue that there was substantial compliance with section 24-32-109's requirement of filing a certified copy of the ordinance with the division of local government.
. We express no opinion whether the Town substantially complied with section 31-12-113(2)(a)(ID(A).
