*919 Opinion
The question before us is whether inverse liability can be imposed on a city for property damage arising from the failure of a public improvement to operate as originally intended. Under the circumstances of this case, we hold it can. Accordingly, we reverse the judgment.
Plaintiff Nathan Yee appeals from a summary judgment entered in favor of defendant City of Sausalito. In plaintiff’s first amended complaint for inverse condemnation, he alleged that a storm drainage system, running along the westerly side of Bulkley Avenue, ruptured, allowing surface water to seep into subsurface soil adjacent to his property which caused massive soil subsidence of his land. Plaintiff charged that the damage proximately resulted from the use of the public improvement as deliberately designed, constructed and maintained, and seeks relief under article I, section 19 of the California Constitution.
In its motion for summary judgment, the city asserted that plaintiff’s complaint, at most, stated a general tort cause of action for negligent maintenance of a public improvement, and not a claim for inverse liability. 1 In support of its motion, the city submitted plaintiff’s answers to interrogatories and responses to requests for admissions. According to these documents, plaintiff stated that the gutter was not functioning as deliberately planned or constructed; that a defect existed in the gutter which proximately resulted in the seepage of water; and that the rupture resulted from the city’s failure to properly maintain the gutter.
Plaintiff opposed the motion claiming that the seepage of the surface water occurred as a direct function of the gutter as originally designed and constructed. He submitted no counterdeclarations or documents.
The trial court granted the city’s motion and entered judgment accordingly. Plaintiff appeals. Specifically, he argues that “[t]he fact that the rupture was not designed or constructed to permit this occurrence is irrelevant when the purpose of the improvement is to prevent the very events and condition of which plaintiff complains. ”
Both parties concede that the damage alleged in appellant’s complaint proximately resulted from the seepage of water through the ruptured gutter. The central question is whether appellant has raised any facts from which it may reasonably be inferred that the damage was proximately caused by the use

of the public improvement “as deliberately planned and built, ...” (See
Albers
v.
County of Los Angeles
(1965)
The principle of inverse condemnation will not subject a public entity to general tort liability. (See
Bauer
v.
County of Ventura
(1955)
For example, in
Eli,
a prison inmate did not state a cause of action for inverse condemnation arising out of the loss of his personal property. The court held “[t]hat loss resulted, rather, from careless (possibly wilful) error of minor public employees in routine day to day operation of the prison system, rather than from any defect in the planned construction or operation of that system.”
(Eli
v.
State of California, supra,
The fundamental justification for inverse liability is that the government, acting in furtherance of public objectives, is taking a calculated risk that private property may be damaged. (Van Alstyne, Inverse Condemnation: Unintended Physical Damage (1969) 20 Hastings L.J. 431, 491.)
In the case of
Albers
v.
County of Los Angeles, supra,
*921 It may thus be fairly stated that the focus of judicial inquiry is not whether the injury was expected or foreseeable, but whether that injury was proximately caused by the use of the public improvement for its intended public purpose. (See Van Alstyne, Inverse Condemnation: Unintended Physical Damage, supra, 20 Hastings L.J. at pp. 434-436.)
The confusion in this lawsuit arises over the interpretation of the phrase “deliberately designed or constructed.” The city asserts that since the gutter was not originally designed or constructed to discharge water into the subsurface soil, it is not liable under inverse condemnation. The city relies on the declaration of Norman Wohlschlaeger, director of public works. According to Wohlschlaeger, the purpose of the storm drainage system was “. . .to convey water along the surface of the gutter, to a storm drain inlet located at Bulkley [Avenue] and Princess Street. ...” and that the “. . . gutter was not in any way designed or constructed in such a manner as to intentionally permit the underground infiltration of waters.” (Italics added.)
Respondent draws an artificial and, for our purposes, legally irrelevant distinction between the intended use of the public improvements and the unintended or unforeseeable damage which necessarily resulted from the use of the storm drainage system. The traditional tort concepts of foreseeability and fault have been eliminated from inverse condemnation actions. (See
Albers
v.
County of Los Angeles, supra, 62
Cal.2d at p. 258;
Ingram
v.
City of Redondo Beach
(1975)
It is acknowledged that the gutter was designed to collect and divert water beyond the houses on Bulkley Avenue into a storm drain. It is also conceded that the damage occurred when surface water, diverted by the gutter, seeped into the soil of property adjacent to appellant’s land. These facts are similar to the cases in which collapse or rupture of a public improvement was found to result in inverse liability.
In
Ingram
v.
City of Redondo Beach, supra,
*922
In
Marin
v.
City of San Rafael, supra,
Similarly, inverse liability has been imposed when water seeped through an irrigation canal, overflowed onto plaintiffs property and damaged his crops.
(Powers Farms
v.
Consolidated Irr. Dist.
(1941)
In this case, the public purpose served by the gutter was to collect and convey surface water away from the surrounding residences. The injury occurred while the improvement was operating as intended. There was no evidence that the injury occurred as a result of the use of the improvement for some purpose unrelated to storm drainage, e.g., as a catch basin for the accumulation of debris. (See
Hayashi
v.
Alameda County Flood Control
(1959)
Practically speaking, the city accomplished its intended public purpose of diverting and collecting rain water in an unintended manner and at plaintiff’s expense. (See
Sheffet
v.
County of Los Angeles, supra,
Respondent’s reliance on
Hayashi
v.
Alameda County Flood Control, supra,
Unlike the events in
Hayashi,
the damage here was not alleged to be caused by the accumulation of debris; an unintended purpose of the storm drainange system. (See Van Alstyne,
Inverse Condemnation: Unintended Physical
*923
Damage, supra,
Based on the record before us, appellant has stated a valid cause of action for inverse condemnation and should be allowed to proceed to trial on the merits, subject to all available defenses.
Accordingly, we reverse the judgment.
King, J., and Haning, J., concurred.
A petition for a rehearing was denied May 4, 1983, and respondent’s petition for a hearing by the Supreme Court was denied June 22, 1983.
Notes
It is alleged that plaintiff failed to file a government tort claim against the city before the statute of limitations expired, and if so, it would appear he has waived his right to seek damages against the city based on general tort liability.
