Opinion

COSGRAVE, District Judge.

Action to quiet title to part of Mormon Island in the inner bay of San Pedro brought by the City of Los Angeles against the Pacific Coast Borax Company and another, after judgment in a former trial reversed on appeal. City of Los Angeles v. Borax Consolidated Limited (C.C.A.) 74 F.(2d) 901; Borax Consolidated v. Los Angeles, 296 U.S. 10, 56 S.Ct. 23, 80 L.Ed, 9.

The plane of mean lower low water was first ascertained in 1878 and the position of its datum plane was preserved by bench mark 10.07. All other bench marks in the district are derived from and based upon this. The evidence shows- that they all have remained constant with the exception of some slight disturbance about 1927. The plane of mean high water was established at about the same time at 5.1 feet above the datum of mean lower low-water. The defendant has introduced evidence to show that, due to the restricted entrance to and shallow depth of the harbor, these two datum planes cannot he held applicable to Mormon Island at the date of the issuance of the patent in 1881. While such condition is reasonably possible, supported as it is by eminent authority, the actual records indicate the contrary, that is, that the two planes existed in 1881 as they do today, both at Mormon Island within the bay and at 10.07 at its entrance.

These elevations were accepted by the United States Coast and Geodetic Survey and all other governmént agencies until 1927 when the Coast and Geodetic Survey, believing that the element of seiche should ' be eliminated, reduced the datum plane of mean high water from 5.1, the value theretofore given, to 4.7, the corrected value.

The first question to be determined is which of the two elevations is to be taken as establishing the line of mean high tide agreeably to the opinion of the .Circuit Court. City of Los Angeles v. Borax Consolidated, supra.

Both parties agree that the datum plane from which tide elevations are measured is that of mean lower low water. The plaintiff in the action contends that mean high tide in the Los Angeles Harbor is 5.1 feet above the datum plane of mean lower low water, while the defendant in the action contends that the true height is 4.7 feet above the same datum plane. The difference arises because of the presence in the Los Angeles Harbor of a phenomenon known as seiche. The regular tides in the harbor have smaller oscillations superimposed upon them, and even these have smaller fluctuations still that vary their ■height. Water movements superimposed upon the regular tides within the harbor produce an alternate rising and falling of the water surface averaging about one complete movement every 53 minutes, and are known as “seiche.” Seiche is not peculiar to Los Angeles Harbor, -but exists there to a greater degree generally than elsewhere. At San Diego the movement is extremely slight, if any. It is not of astronomic origin as are the tides themselves, but is caused by terrestrial forces such as changes in barometric depression, storms, and even earthquakes. This movement of water thus imposed upon both the advancing and receding tides alternately carries the surface of the water to a point higher than the general ocean level and, immediately following, drops it back below such level.’ The United States Coast and *71 Geodetic Survey lor a long period of time, in fact up to about 1926, in registering the height of the tide included the extreme height, that is, the height that the water reached at the highest point of the seiche movement, disregarding the height at the recession of the seiche immediately thereafter. Similarly, in registering the lowest point reached by the receding tide, they registered that at the lowest point of the seiche movement. Due to further' study and investigation, the Survey in 1926, deeming the extreme height a false quantity, decided to average the height of the tide as between the highest point reached in the seiche and the low point immediately preceding or following it. The method is graphically described on the Plaintiff’s Exhibit 31, a marigram of the automatic tide recording device placed at the entrance to the harbor, where, on a scroll driven by clock work, the actual variations of the tide level are recorded on a much reduced scale. A continuous line is drawn through the inequalities produced by the seiche, and this is adopted by the Coast and Geodetic Survey as the true height of the tide. • U. S. Coast and Geodetic Survey, special publication No. 135, Tidal Datum Planes, p. 30.

It seems to me that this practice of the Survey is the correct practice. The height of mean high water itself is ascertained by averaging the height of all the higher tides; which is doing on a large scale what the Survey now does on a smaller scale with respect to the seiche. While it is literally true that the height thus obtained is not the actual height attained by the tide, it is nevertheless true that the extreme height is temporary only and that at the end of a period being one-half of the 53-minute period of oscillation, it is at a considerably lower level, the variance being often times more than a foot. The plaintiff itself in recording the tidal values within the harbor averages or smooths out the minor fluctuations upon the seiche, referred to on this marigram and on others introduced in evidence as “saw teeth” and which seem always to exist and at times average some twenty to the hour.

The Los Angeles Harbor is the only harbor following the rule contended for by the plaintiff, that is, where the extreme limits rather than the average of seiche movement is adopted. The theory upon which the level of mean high water itself is ascertained, that is, the average height of all the high tides; the practice of the plaintiff itself in averaging the minor variations of the seiche movement; considerations of uniformity of practice by the Coast and Geodetic Survey — all suggest that the value of 4,7 adopted by the United States Coast and Geodetic Survey, for the level of mean high tide in Los Angeles Harbor, be taken as the correct value for the purposes of the present case.

Having reached a conclusion as to the correct height of the plane of mean high water, the next question to be determined is where this plane intersected the surface of Mormon Island in 1880, being the date of the survey on which the United States patent was issued.

Norway surveyed the island in 1880; his field notes are not in evidence. TSos che made the next survey in 1883; Turner in 1899, all before any change had been made in the surface of the island; and Fitzgerald in 1909 while some work was in progress. These surveys are in substantial agreement and show only a small part of the land that was included in the Norway survey to be more than 4.7 feet above the plane of mean lower low water. The correciness of these surveys is confirmed to a considerable extent by defendant’s own investigations, which it made shortly before the trial of the action by means of pits and excavations designed to reveal the elevation of the original surface of the island. The location of the 4.7 level is fairly shown on the composite map, a summary of all the surveys, introduced by the plaintiff.

That the original surface of the island has been sensibly lowered by the weight of buildings, levees, by dredging of adjacent channels or by earth movements I think is unlikely.
