The appellee is the owner of lot 17, block 3, of the city of Tucson. Lots 18, 19, and 20 in same block are *357owned by one Allen B. Jaynes. All these lots face on First street, and lot 20 is on the west side of Third avenue. Block 3 was a part of the original grant by the United States government to the city of Tucson. It was platted into lots, and First street and Third avenue were dedicated by the city. Extending across block 3 and lots 17, 18, 19, and 20 thereof was a natural swale or depression, the general course of which was southwesterly and northeasterly. This swale reached easterly some distance from block 3, across Third avenue, and across block 2, and into it rain and surface waters gathered and were carried off into First street at a point a little west of lot 17. While-block 3 was in this natural condition, appellee and Jaynes purchased the named lots for the purpose of building thereon dwelling-houses. The surface of lots was filled in and raised to about ten inches above the proposed grade of First street; the raised surface extending back and covering and obliterating the swale. Along the east side of lot 20 and the west side of Third avenue and in the avenue, Jaynes, for the purpose of carrying flood or rain water off his property, constructed a ditch from the swale down to First street. He says: “At the time I improved my property, I scooped out a ditch down First street; that is, started on Third avenue. There was a very slight ditch on Third avenue. It was low, anyway, there; we just built up dirt on either side. . . . ” This ditch on Third avenue, prior to its being filled and prior to the damage complained of, had been of sufficient capacity to carry off all the water coming down the swale. In April or May, 1910, the city ivas improving or grading Fourth avenue, and the city engineer caused some of the waste material taken from Fourth avenue to be deposited on Third avenue, extending from First street north about 100 feet. The surface of Third avenue was raised, and the ditch that had been made by Jaynes was filled up so that on July 21, 1910, when it rained, a large body of water was collected, forming a kind of basin. The dirt filled in Third avenue and in the ditch, prevented the water from escaping, as it had done before, down on to First street, and forced it over and across lots 20, 19, and 18 parallel to and about ten feet north of the old depression on to appellee’s lot 17, and filled his cellar full of water, destroying and damaging property of the value of $333.50.
*358The contractor who was making the improvement on Fourth avenue dumped the waste earth on Third avenue under the authority of a stipulation in his contract with the city, to the effect that “all waste material shall be disposed of as directed by the city engineer.” The ditch along Third avenue had been constructed and in use for about ten months before it Avas filled up.
The case was tried before a jury. Verdict and judgment for appellee. The city appeals and assigns fifteen errors based upon the giving and refusing instructions and in the admission and rejection of evidence.
The instructions given, of which complaint is made, were based upon the theory that, if the facts alleged in plaintiff’s complaint were true, the city was liable in damages, and the instructions requested by appellant and refused were based upon the theory: (1) That the filling of swale or depression of lots 17, 18, 19, and 20 by Jaynes and appellee did not relieve the premises of the servitude of the surface water theretofore naturally running over and across their premises; (2) that the ditch made by Jaynes to convey the water along Third avenue to First street and away from premises was made without authority, and the city acted within its rights in filling it up; (3) that surface of premises was permitted to remain below the established grade, but for which the injury would not have occurred; (4) that the act of the city engineer and contractor in dumping Avaste earth on Third avenue was not the act of the city and could not bind the city; and (5) granting that the city had done all the things charged against it, it was acting within the law, and any damages suffered by appellee were only consequential of the exercise of its rights and damnum absque injuria.
We will consider the appellant’s contentions in the order given. It will be borne in mind that the city sold the premises to appellee and Jaynes for residential purposes. It was apparent that homes could not be built thereon without filling in and leveling up the surface of lots. The right to raise the surface of lots and obliterate the swale or depression extending over them was as clearly implied and understood between the purchasers and seller as if it had been stipulated in the deeds of conveyance. Therefore, in filling in their lots and raising the surface thereof, the purchasers did what *359was in the contemplation of the city and what they were authorized to do under the law.
In a broad sense and as a general proposition there is no dominant or servient estate as applied to surface or rain waters.
The doctrine of the respective rights of adjoining owners of realty has been many times before the courts, and, as applied and administered under what is known as the so-called common-law rule, is fairly comprehended and limited by the following quotations:
“One is under no obligation to receive from the other the flow of any surface water, but may, in the ordinary prosecution of his business and in the improvement of his premises, by embankments or otherwise, prevent any portion of surface water coming from such upper premises.” Walker v. New Mex. S. P. R. Co., 165 U. S. 593, 41 L. Ed. 837, 17 Sup. Ct. Rep. 421.
“The lot of the defendant is in the midst of a populous city. The rule which governs the right to dispose of surface water in agricultural districts does not apply to such property. It is set apart, held, and owned for building purposes. To make it useful' for this purpose, the owner has the right to fill it up, elevate it, to ditch it, to construct buildings on it in such a manner as to protect it against the surface water of an adjoining lot. If in so doing he prevents the flow of surface water upon his lot, the owner of the higher lot has no cause of action against him. This is a necessary incident to the ownership of such property. A contrary rule would operate against the advancement and progress of cities and towns and to their injury, and would be against public policy.” Levy v. Nash, 87 Ark. 41, 20 L. R. A., N. S., 155, 112 S. W. 173.
“The owners of lots in cities and towns buy and own with the manifest condition that the natural or existing surface is liable to be changed by the progress of municipal development. All such owners have equal rights neither lessened nor increased by priority of improvement, and the primary right of each owner is to protect himself and his lot from loss or inconvenience from the flow'- of surface water. The owner at the foot of the slope is under no obligation to allow his lot to continue as a reservoir for the surplus water of the neigh*360borhood. He may shut it out by grading or otherwise, and the fact that thereby he may incidentally increase the flow on the adjoining lot neither makes him answerable in damages nor affects, the adjoining owner’s right in his turn to shut out the original, plus the increased, flow on his lot. The owner cannot be coerced as to time or manner of improvement by risk of having put upon him the burden of providing for the flow upon others. Some things, of course, he may not do. He may not proceed negligently so as to do unnecessary damage to others. But, so far as he acts upon his right to protect his enjoyment of his own property, any incidental loss to his neighbor is damnum absque injuria.” Reilly v. Stephenson, 222 Pa. 252, 256, 128 Am. St. Rep. 804, 22 L. R. A., N. S., 947, 70 Atl. 1097, 1099.
The rule as announced in the above eases was recognized by this court in Kroeger v. Twin Buttes R. R. Co., 14 Ariz. 269, Ann. Cas. 1914A, 1289, 127 Pac. 735.
The effect of the improvements made by appellee and Jaynes, upon the surface water, was to completely change its course from their premises along the drain or ditch on Third avenue. This ditch had been constructed by Jaynes and was in use when appellee began his improvements. Appellee’s premises were distant from it the width of Jaynes’ three lots and an alley. The suggestion by appellant that the making of this ditch in the street was a trespass, if granted as true, could hardly affect appellee, as he had no part in its construction.
Besides, even though Jaynes had obtained no permission to construct the ditch, its use for some ten months, without any objection on the part of the city, would justify a presumption that he had secured the consent of the city to construct it, or by its silence it had ratified his act. The city, as original owner of the premises and the coterminous streets, was fully aware of the conformation of the land and necessities of the situation, and doubtless willingly acquiesced in what was done by Jaynes toward protecting his premises. It is not claimed that the ditch made by Jaynes in any way interfered with the use by the general public of Third avenue or that the avenue was in any manner injured, while it must be conceded that such disposition of the surface water was not only practicable but of incalculable benefit to all the premises *361protected. In Sheehan v. Flynn, 59 Minn. 436, 26 L. R. A 632, 61 N. W. 462, the court said: “The common-law rule as to liability for the diversion of surface water has been modified in this and other states by the rule that a person must so use his own as not unnecessarily or unreasonably to injure his neighbor. A circumstance to be considered in determining what is reasonable use of one’s own land is the amount of benefit to the estate drained or improved, as compared with the amount of injury to the estate on which the burden of the surface water is east. Hughes v. Anderson, 68 Ala. 280, 44 Am. Rep. 147. ‘But the extent to which any proprietor may go in these and other ways, in incidentally, while improving his own land, turning the surface water of his own land off on the lands of others, must, in each ease, be determined by the degree of comparative injury it may produce and relieve.’ Ray on Negligence of Imposed Duties, 301. The benefit in this case will be the redeeming of twenty acres of fine agricultural land, and the restoring of this highway, while the injury will be the submerging, for some time in the spring, of an acre or two of such land as is found along the shore of such a lake. It seems to us that the extent to which the common law is thus modified is well expressed in the case of O’Brien v. St. Paul, 25 Minn. 335, 33 Am. Rep. 470, where it is said: ‘It [surface water] has been called a common enemy, which each owner may get rid of as best he may; and some cases, and not a few, indeed, maintain the owner’s right to adopt any means he may choose to prevent it coming on his land, or to turn it off from his land, without regard to* the consequences which may ensue 'to others. These cases are founded on an owner’s assumed right to do absolutely" what he will with his own. This right, however, is somewhat restricted by the maxim that “a man must so use his own as not unnecessarily to do injury to another,” a maxim which grows out of the necessities of society, and without which society would be hardly possible. A man’s right to use his property is restricted, for instance, to the manner in which such property is ordinarily used.’ Again, on page 336, it is said: ‘Although we are not prepared to say that in no case can an owner lawfully improve his own land in such a way as to cause the surface waters to flow off in streams upon the land of another, we do not hesitate to say *362that he may not turn the water, in destructive currents, upon the adjoining land. . . . From the complaint, there does not appear any necessity, in grading the avenue, to collect the water at the point indicated, nor any difficulty in conducting it off without injury to private property.’ This is a reasonable doctrine that takes into consideration all the circumstances of each case. It gives each man the common-law right to improve and enjoy his own property to its fullest extent, but limited by the requirement that he use reasonable care in disposing of surface water, which the common law did not always require him to do. When he has used such reasonable' care, he can generally stand on his common-law rights, whether such surface water injures his neighbor or not.” Hume v. City of Des Moines, 146 Iowa, 624, Ann. Cas. 1912B, 904, 29 L. R. A., N. S., 126, 125 N. W. 846.
Appellee and Jaynes had filled in the front of their lots and raised the surface thereof to or slightly above the established grades of First street and Third avenue. This filling on lots 18, 19, and 20 extended some feet north of the swale and entirely obliterated it. Appellee had also filled up and obliterated the swale on his lot 17. Where the water broke over on to the Jaynes premises, the surface was not raised to the proposed grade of the street, but was some higher than the natural surface of the street, so that it formed one of the walls of the basin of water that collected and was precipitated on appellee’s premises. That the back end of premises was lower than the proposed grade of Third avenue cannot advantage the appellant, unless that fact, and not the filling in of ditch and Third avenue, caused the damage to appellee. It was not necessary that the entire surface of premises should have been raised to the proposed grade to entitle appellee to protection from negligent and wrongful injury. The action of the city should have been in view of the existing conditions, as were the precautions taken by appellee. If the .city had been in the actual prosecution of the improving and grading Third avenue, exercising reasonable care and caution, and the injury had been a mere incident to such work, the appellee would be remediless. Johnson v. White, 26 R. I. 207, 65 L. R. A. 250, and notes “a” and “b,” 58 Atl. 658. But in this case the waste material and earth placed in Third avenue and Jaynes’ ditch were not placed *363there in pursuance of any definite plan of present improvement, but with a view of future needs in raising the grade of said avenue.
The act of the city engineer in causing the contractor to dump the waste earth in Third avenue was the act of the citjr. The contract for the improvement of Fourth avenue authorized the contractor to place the waste (within certain limits) as directed by the engineer. The engineer, acting within the authority given him, was performing and acting for the city, and his acts were the city’s acts. Municipal corporations, like other corporations, can act only by their servants and agents. 28 Cyc. 1269.
"We are now brought to the main question, as to whether the city, in any event and in view of all the facts, is liable in damages to appellee. Municipal corporations in the control and disposition of surface waters are bound by the same rule as are private persons. Gould on Waters, section 272, sas^s: ‘ ‘ Cities and towns have no greater rights than individuals to collect in artificial channels, upon their streets and highways, mere surface waters, distributed in rain and snow over large districts, and precipitate it upon the premises of private owners, or to construct ditches upon private lands for public uses without compensation. A municipal corporation is liable for throwing water, collected in large quantities in a street, or in a gutter of a street, upon the land of a private owner.” Jordan v. Benwood, 42 W. Va. 312, 57 Am. St. Rep. 859, 36 L. R. A. 519, 26 S. E. 266.
In the performance of administrative acts, the rule almost universally accepted at the present time is that a municipal corporation is liable for injuries caused by negligent or wrongful acts of its servants and agents, for which it is responsible.
Now, while the surface waters formerly followed the natural depression over appellee’s premises, acting within their rights in grading and improving their lands, another depression, artificial, it is true, but natural in its uses, was made through which such waters escaped, much to the benefit of the premises, with no apparent or claimed injury to the city. The improvement of urban property necessarily works changes in the conformation of the surface ground, and what to-day may be the natural channel of drainage, to-morrow *364may be occupied by buildings. As was said in Larrabee v. Cloverdale, 131 Cal. 96, 63 Pac. 143: “And this, on principle, must be the true construction of the term ‘natural •channel,’ when used in the present connection. For, by.the necessarily great changes that must occur in the conformation of the country in the building uf a city, the natural channels for the surface water are changed; and as the changes in the ground are inevitable and legitimate, and therefore natural, the new channels, through which, under natural laws, the surface. waters are discharged, must also be regarded as natural. ’ ’
Without doubt the city had the same rights to improve its streets as appellee had to improve his property. To that end it could have raised the surface of Third avenue to the established grade and adopted means and plans to protect it from the surface waters brought upon it. The waste material that it dumped on Third avenue was not for present use, but for use some time in the future in grading the avenue and raising its surface. It was in preparation for contemplated work. It did not keep the water from the avenue, but impounded it on the avenue in a basin or reservoir from which it wras precipitated on to appellee’s premises in a greater volume and with added force. It made an embankment across the channel through which the surface waters had naturally passed for almost a year. It knew, or could have known by ordinary care, that the embankment made by it would deflect and precipitate the waters onto appellee’s premises. Failing to provide an outlet made necessary by its own acts, it is guilty of an actionable wrong. City of Evansville v. Decker, 84 Ind. 325, 43 Am. Rep. 86; Valparaiso v. Kyes, 30 Ind. App. 447, 66 N. E. 175; Weis v. City of Madison, 75 Ind. 241, 39 Am. Rep. 135.
The annotator to Johnson v. White, II, note, “b,” 65 L. R. A. 262, says: “Notwithstanding the difference of opinion as to liability for changing the course of drainage, there is practical unanimity in holding that the water cannot be gathered up and cast in a body on the adjoining property”-—and cites a long list of cases sustaining the principie announced.
The refusal of the court to instruct on the theory of the nonliability of appellant, as contended for by it, was not *365error. The instructions given properly submitted the issue of negligence to the jury.
One of the defenses of the appellant was that the damage that plaintiff sustained by reason of the flooding of his premises “was approximately caused by said sudden, violent, extraordinary, unforeseen, and unanticipated storm of rain.” Upon this issue the court gave the following instructions:
“The term ‘act of God,’ in its legal sense, applies only to events in nature so extraordinary that the history of climatic variations and other conditions in the particular locality afford no reasonable warning of them; and liability for injury occasioned by floods of water, where liability would otherwise attach, cannot be avoided on the ground that the flood was an act of God, where, from the climatic and geographical conditions, the flood might have been expected, though it occurred infrequently.”
“You are further instructed that even though the city had caused the earth and other material to be dumped on Third avenue at the point alleged in plaintiff’s complaint and testified to in this action, yet if you should further find that the storm that is alleged to have caused the injury to plaintiff’s property was so overwhelming in character that it would, of itself, produce the injury complained of, independently of the said earth and other material, then your verdict must be for the defendant.”
“The jury are instructed that, to give a stream or body of water the character of an extraordinary flood, it is not necessary that it should be the greatest flood within memory. Its character in this respect is to be tested by comparison with the usual volume of floods ordinarily occurring.”
The appellant complains of the first and last subdivision of these instructions and insists that they do not state the law and are contradictory. Admitting the point made, yet we think, when the whole language on that question is construed and analyzed, the thought conveyed to the jury was that, if the storm would have caused the injury independent of the obstruction placed in Third avenue, the verdict should be for appellant. In other instructions the jury were told that before they would be authorized to return a verdict for the plaintiff, they must find, by a preponderance of the evi*366deuce; that the injury was caused by the obstruction placed on Third avenue by appellant.
The evidence is that the rainfall for two hours was 1.35 inches. The appellant asked questions of witnesses as to whether such amount of rain was extraordinary or not. It complains that the court erred in sustaining an objection to the witness answering the question. Witnesses were permitted to state, over objection by appellant, that other rains previous and subsequent to July 21, 1910, were extraordinary, without giving the duration of the fall. Of this evidence complaint is made. As we view the facts in the case, the character of the rain, whether ordinary or extraordinary, can have little bearing, since, whatever its character, it had but one outlet, and that outlet was over appellee’s premises. The evidence showed that other rains of equal or greater volume before the obstruction of Third avenue had passed down that avenue on to First street and not on to appellee’s premises.
Judgment affirmed.
