delivered the Opinion of the Court.
¶1 This is thе latest chapter in the legal saga of a young girl who was seriously injured on her elementary school playground in late 2008. Alexa Rae Loveland, then nine years old, fell while using the playground’s zip line apparatus and severely fractured her wrist and forearm. Alexa and her parents filed a tort action against the school district, seeking damаges for Alexa’s injuries. Because the Colorado legislature has limited when public entities such as the school district may be sued, we are asked to determine whether the Lovelands’ lawsuit falls within one of the limited exceptions to sovereign immunity under the Colorado Governmental Immunity Act (“CGIA,” or “the Act”), §§ 24-10-101 to -120, C.R.S. (2016). Specifically, Alexa and her parents invokе the recreation-area waiver, which deprives a public entity of immunity in an action for injuries resulting from a dangerous condition of a public facility located in a recreation area,
¶2 We hold that a non-negligently constructed and maintained piece of playground equipment cannot be a “dangerous condition” under the CGIA’s rеcreation-area waiver. Because the facts the Lovelands allege cannot satisfy the dangerous-condition requirement, the recreation-area waiver does not apply, and the District’s immunity under the CGIA remains intact. The trial court was correct to conclude that it lacked jurisdiction over the Lovelands’ tort action аnd to grant the District’s motion to dismiss. Accordingly, we reverse the judgment of the court of appeals, and we remand to that eourt to reinstate the trial court’s order dismissing the complaint in this case.
I. Pacts and Procedural History
¶3 In 2008, then-nine-year-old Alexa Rae Loveland fell while using the zip line apparatus on her school playground and fractured her wrist and right forearm. The zip linе was a piece of inclined pipe that ran between two sets of vertical poles secured in the ground. The inclined pipe had a handle attached to an interior track, and to use the zip line, a child would climb up a short ladder, stand on an elevated platform to grab the handle, and propel him- or herself forward down the zip line track, releasing the handle and jumping to the ground at the end of the track. There was also a sign that warned “Adult Supervision Required.”
¶4 This is not the first time we have considered issues related to this case. After Alexa’s injury, she and her parents (“the Lovelands”) filed a tort action against the St. Vrain Valley School District (“the District”). The District moved to dismiss the action, arguing the trial eourt lacked subject matter jurisdiction because public school districts are immune from tort liability under the CGIA. The District acknowledged that section 24-10-106(l)(e), referred to as the recreation-area waiver, deprives a government entity of immunity if an injury results from a “dangerous condition of any ... public facility located in any park or recreation area maintained by a public entity.” But the District argued that the Lovelands could not establish the elements of the recreation-area waiver in this case for a number of reasons, one of which was that the zip line was not a public facility. The Lovelands countered that the zip line was in fact a public facility and a dangerоus condition of a public facility. The trial court agreed with the District. It found that the zip line was not a public facility, and therefore that the recreation-area waiver did not apply. The court granted the District’s motion to dismiss.
¶5 The Lovelands filed an interlocutory appeal. The court of appeals reversed the trial court’s ruling and held -that the zip line was a public facility. See Loveland ex rel. Loveland v. St. Vrain Valley Sch. Dist. RE-1J,
¶6 The District sought this court’s review of the court of appeals’ decision. We granted certiorari and affirmed on different grounds. St. Vrain Valley Sch. Dist. RE-1J v. A.R.L. ex rel. Loveland (“St. Vrain I”),
¶7 On remand, the District again moved to dismiss, arguing that the recreation-area waiver did not apply because the Lovelands failed tо establish a dangerous condition on the zip line. Applying the CGIA’s definition of “dangerous condition,” the trial court granted the District’s motion. The court explained that the Lovelands • failed to assert what specific physical or structural condition made the zip line a “dangerous condition” as that term is defined in the statute and as distinguished from their general assertion that a zip line is inherently dangerous. The trial court concluded that the Lovelands failed to state a claim sufficient to overcome the District’s sovereign immunity. -•
18 The Lovelands appealed, and the court of appeals again' reversed. The court of appeals concluded that an individual playground appаratus, such as the zip line in this case, is a physical condition for purposes of the dangerous-condition test. Loveland v. St. Vrain Valley Sch. Dist. RE-1J (“Loveland II”),
¶9 We granted the District’s petition for certiorari review. 1

¶11 Because the CGIA derogates the common law, we must strictly construe its immunity provisions, but broadly construe its provisions waiving that immunity. Springer v. City & Cty. of Denver,
III. Analysis
¶12 We first examine the CGIA provisions governing our analysis. We then assess whether the Lovelands have alleged facts sufficient to establish that the ziр line was a dangerous condition, thereby depriving the District of immunity from suit here. The Lovelands argue that the zip line was inherently dangerous; they do not present evidence that the zip line contained a physical *755 defect caused by the District’s negligent construction or maintenance. Because such evidence is required to establish the existеnce of a dangerous condition, we conclude that the Lovelands’ claim is insufficient to defeat the District’s sovereign immunity.
A. The CGIA and “Dangerous Condition” Under the Recreation-Area Waiver
¶13 The CGIA establishes that a public entity shall be immune from any action for injury which lies in tort or could lie in tort, except as specifically provided elsewherе in the Act. § 24-10-108. The Lovelands seek to invoke the recreation-area waiver, which eliminates governmental immunity for injuries resulting from á “dangerous condition of any ... public facility located in any park or recreation area maintained by a public entity.” § 24-10-106(l)(e) (emphasis added).
¶14 In St. Vrain I, ¶¶ 35-36,
¶15 The CGIA provides the following definition of “dangerous condition”:
“Dangerous condition” means either a physical condition of a facility or the use thereof that' constitutes an unreasonable risk to the health or safety of the public, which is known to exist or which in the exercise of reasonable care should have been known to exist and which condition is proximately caused by the negligent act or omission of the public entity or public employee in constructing or maintaining such facility. For thе purposes of this subsection (1.8), a dangerous condition should have been known to exist if it is established that the condition had existed for such a period and was of such a nature that, in the exercise of reasonable care, such condition and its dangerous character should have been discovered. A dangerous condition shall not exist solely because the design of any facility is inadequate. The mere existence of wind, water, snow, ice, or temperature shall not, by itself, constitute a dangerous condition.
§ 24-10-103(1.3).
¶16 This court has segregated the CGIA’s definition of “dangerous condition” into a four-factor test. The waiver applies if the injuries occurred as a result of: (1) the physical cоndition of the public facility or the use thereof; (2) which constitutes an unreasonable risk to the health or safety of the public; (3) which is known to exist or should have been known to exist in the exercise of reasonable care; and (4) which condition is “proximately caused by the negligent act or omission of the public entity in constructing or maintaining the fаcility.” See Springer,
1Í17 With this general framework in mind, we turn to the Lovelands’ proposed application of the term “physical condition.”
B. “Dangerous Condition” Requires a Physical Defect in the Construction or Maintenance of the Apparatus
¶18 To show that the zip line was a dangerous condition under the foregoing test, the Lovelands focus on the meaning of “physical condition,” arguing that there is nothing in the statute or case law that prevents the zip line itself—rather than some condition of the zip line—from being thе relevant “physical condition” here. The court of appeals took a similar approach, concluding that “an individual playground apparatus is a physical condition of a playground.” Loveland II, ¶ 17. But the Lovelands and the division’s interpretation fails for at least' two reasons. First," it does not square with existing precedent. Secоnd, it fails to recognize that the second through fourth factors of the dangerous-condition test modify the first, such that whether something is a “physical condition” cannot be determined without reference to the other factors; if any one of those other fáctors is hot satisfied, there can be no “physical condition” for purposes of the *756 dangerous-condition test. We address these two points in ton.
¶19 First, this court’s previous cases interpreting section 24-10-103(1.3) have suggested that in order to be a “dangerous condition” within the meaning of that section, a “physical condition” must be a physical or structural defect. See Jenks v. Sullivan,
¶20 Second, the other factors in the dangerous-condition test further limit what can be a “physical condition” for purposes of the test. Most important for our analysis, the physical condition must be caused by some negligent act or omission of the public entity in constructing or maintaining the facility. For example, in Padilla ex rel. Padilla v. Schоol District No. 1,
¶21 In sum, the statutory language at issue and our precedent support the notion that the Lovelands must prove a defect in the condition of the zip line. But they do not even allege such a defect. Instead, they make what amounts to a design argument, which we address next.
C. The Playground Design Argument Fails
¶22 The Lovelands claim that they have indeed alleged a negligent act related to construction: they submit that the District’s negligent act was its decision to construct the zip line on the school playground. They argue that a District employee made the decision to purchase and install the zip line and that thе employee knew or should have known that a zip line is dangerous. Even so, this is an argument about the design of the playground, which section 24-10-103(1.3) clearly prohibits. § 24-10-103(1.3) (“A dangerous condition shall not exist solely because the design of any facility is inadequate.”); see also, e.g., Estate of Grant v. State,
¶23 The Lovelands argue that the zip line satisfies the dangerous-condition test because the zip line was inherently dangerous and that the District was negligent in, placing something inherently dangerous on the playground. But the recreation-area waiver does not recognize such blanket claims of danger based on the design of a public facility. On the contrary, it explicitly precludes such claims.
IV. Conclusion
¶24 A non-negligently constructed and maintained piece of playground equipment cannot be a “dangerous condition” under the CGIA’s recreation-area waiver. Because the facts the Lovelands allege cannot satisfy the dangerous-condition requirement, the recreation-area waiver does not apply, and the District’s immunity under the CGIA remains intact. The trial court was correct to conclude that it lаcked jurisdiction over the Lovelands’ tort action and to grant the District’s motion to dismiss. Accordingly, we reverse the judgment of the court of appeals, and we remand to that court to reinstate the trial court’s order dismissing the complaint in this case. 3
Notes
. We granted certiorari to review the following issues:
1. Whether the court of appeals erred in broadly defining "dangerous condition” within, section 24-10-103(1.3), C.R.S, (2015), of the Colorado Governmental Immunity Act ("CGIA”), to include a playground apparatus with no physical condition, thereby waiving governmental immunity for all playground equipment.
2. Whether the court of appeals erred in holding that the existence of a warning sign from the manufacturer on a piece of playground equipment, in and of itself, renders the equipment an unreasonable risk to the health or safety of the public for purposes of establishing that element of a “dangerous condition” within the CGIA.
. Longbottom v. State Board of Community Colleges & Occupational Education,
. Because we conclude that the Lovelands’ claim is insufficient for the reasons stated above, we do not reach the second question on which we granted certiorari review, which asks us to interpret the second factor of the dangerous-condition test.
