Robert Bennett and the other plaintiffs/landowners appeal from the trial court’s order dismissing Provo City as a party defendant. The order has been certified as a final order pursuant to rule 54(b) of the Utah Rules of Civil Procedure. The dismissal was based on governmental immunity or, in the alternative, failure by plaintiffs to provide proper notice to the City within one year pursuant to Utah Code Ann. § 63-30-13 (Supp.1985).
In 1974, Provo City sought a location for a water storage tank and found a site at the mouth of Little Rock Canyon, owned by Flying Diamond, which later changed its name to Bow Valley Development. Bow Valley also owned an adjacent tract of land which it planned to develop as a residential subdivision called Sherwood Hills. Plaintiffs allege that in exchange for the tank site and access to it, Provo City officials agreed that Bow Valley would be given permission to develop the subdivision.
Plaintiffs purchased homes in the Sherwood Hills subdivision between 1978 and 1983. They complain that three major landslides, numerous smaller slides, two road closures, property damage, and deterioration of roads, sidewalks, and utilities occurred in the subdivision. They allege that these occurrences were caused by Bow Valley’s filling natural drainage channels, failing to comply with grading plans, failing to construct roads in a safe manner and with proper compaction, and failing to re-vegetate cut slopes. The dates of these events do not appear in the record.
Plaintiffs further assert that despite Bow Valley’s alleged negligence, Provo City released improvement bonds furnished by Bow Valley without requiring it to make the necessary improvements in the subdivision and that this constituted negligent release of bonds. Finally, plaintiffs charge that the City failed to safely maintain the storage tank and their property has been damaged by leakage from and landslides created by the tank.
Plaintiff Bennett sent written “notice of claim” to Provo City on May 28, 1985. Approximately fifty other plaintiffs sent a similar notice on January 31, 1986. Plaintiffs filed this complaint on March 6, 1986.
The Utah Governmental Immunity Act, Utah Code Ann. §§ 63-30-1 to -38 (Supp. 1985), establishes governmental immunity “for any injury which results from the exercise of a governmental function,” subject to various statutory waivers. Utah Code Ann. § 63-30-3. In 1987, the legislature enacted its own definition of “governmental function.” See § 63-30-2(4)(a) (1989). However, since this case arose prior to that enactment, we consider the definition of governmental function solely under case law applicable before the 1987 amendment:
This Court has held that the test for determining a governmental function for governmental immunity purposes “is whether the activity under consideration is of such a unique nature that it can only be performed by a governmental agency or that it is essential to the core of governmental activity.” Standiford v. Salt Lake City Corp.,605 P.2d 1230 , 1236-37 (Utah 1980). We later elaborated that the Standiford test “does not refer to what government may do, but to what government alone must do” and includes “activities not unique in themselves ... but essential to the performance of those activities that are uniquely governmental.” Johnson v. Salt Lake City Corp.,629 P.2d 432 , 434 (Utah 1981) (emphasis in original).
Rocky Mountain Thrift Stores v. Salt Lake City Corp.,
Plaintiffs’ claims must be separately examined to determine whether each activity complained of was a governmental function *422 and, if it was, whether a statutory waiver applies. Where waiver applies, a timely notice of claim is required under sections 63-30-11 to -13.
We deal first with plaintiffs’ equity claim, which does not involve immunity analysis.
See El Rancho Enters. v. Murray City Corp.,
We next consider plaintiffs’ claim for damages arising from the negligent maintenance of the water storage tank. Is the operation and maintenance of a water storage tank a governmental function? We held that under the
Standiford
and
Johnson
tests, the construction, operation, and maintenance of a city-wide storm drainage system is a governmental function.
Rocky Mountain Thrift Stores,
[W]e do not agree that these functions are uniquely governmental or essential to the core of its activity. It is not even mandatory that a governmental entity perform these functions. In many rural and recreational areas of our state, individual homeowners or small clusters of homes legally provide their own sewer services with septic tanks.
Thomas,
We next address plaintiffs’ claim for a private nuisance caused by defective public improvements, including streets, curbs, gutters, sidewalks, and utilities. Immunity for damage arising therefrom is waived under section 63-30-9, which provides: “Immunity from suit of all governmental entities is waived for any injury caused from a dangerous or defective condition of any public building, structure, dam, reservoir or other public improvement. Immunity is not waived for latent defective conditions.”
See Sanford v. University of Utah,
Turning to plaintiffs' tenth claim for relief, they complain that Provo City negligently released the subdivision improvement bonds furnished by Bow Valley. They charge that Bow Valley failed to complete and maintain serviceable roads, sidewalks, and curb and gutter in a safe manner and with proper compaction and failed to revegetate cut slopes to prevent erosion,
*423
which caused damage to their property. They argue that the bonds should not have been released until these conditions were remedied, and they seek to interpret
Cox v. Utah Mortgage and Loan Corp.,
In Cox, the developer had placed money in escrow to guarantee construction of the off-site improvements. The funds allegedly were negligently released by the city before the completion of the improvements. Our decision rested on a narrow ground:
Pleasant Grove admitted that it was unable to determine for what three releases of money totalling approximately $61,000 were made in payment. That admission raises a significant factual dispute on the issue of failure to properly supervise disbursements of funds, precluding a judgment in favor of Pleasant Grove as a matter of law.
Cox,
The plaintiffs in
Cox
attacked the negligent supervision of the escrowed funds, which we held not to be a governmental function. The act of releasing funds and being accountable to know for what purpose they are being released is “an escrow function with no aspects of uniqueness, but [is] capable of being performed by anyone.”
Loveland v. Orem City Corp.,
Plaintiffs allege in their twelfth claim for relief that Provo City engaged in a conspiracy to defraud. This claim also attacks subdivision approval. Plaintiffs argue that subdivision approval was a representation that Sherwood Hills was safe and suitable for residential use and Provo City knowingly withheld information' of the unstable conditions. In
Loveland,
this court concluded that the city planning commission’s receipt and analysis of subdivision plat and approval were activities done in exercise of a governmental function.
Loveland,
It follows that in the instant case only Provo City can balance all of the competing interests when development of land is sought. Therefore, the city planning commission’s receipt and analysis of subdivision plat and approval were activities in the exercise of a governmental function and therefore were protected by governmental immunity. For the reasons we have heretofore enumerated, there is no waiver of immunity. In addition, section 63-30-10 provides that immunity is not waived for acts or omissions of employees acting within the scope of their employment when a plaintiff’s injury arises out of deceit or misrepresentation by the employee. Utah Code Ann. § 63-30-10(l)(b) & (f) (Supp.1985).
Plaintiffs’ last claim is that their property has been damaged or taken for a public use without just compensation by Provo City, including Provo’s failure to maintain roads and other public improvements, in violation of amendment V of the United States Constitution and article I, section 22 of the Utah Constitution. See our recent opinion in
Colman v. Utah State Land Board,
In sum, we conclude that plaintiffs’ equitable claim is not barred by governmental immunity and need not conform to statutory notice requirements.
See El Rancho Enters. v. Murray City Corp.,
We reverse and remand to the district court for further proceedings consistent with this opinion.
