The Twin Peaks tunnel pierces the high ridge which separates the more densely populated portion of San Francisco from the large-and comparatively level region lying west of the said ridge and constituting the watershed of Lake Merced. The length of the tunnel is eleven thousand two hundred feet. It was constructed by the city and county of San Francisco under the authority of chapter VIII, article VI, of the San Francisco charter, and under the procedure provided by an ordinance passed by the board of supervisors of San Francisco, pursuant to authority given in said chapter, on October 20, 1913. For the cost of making the tunnel an
*5
assessment was levied by the city in said proceeding, covering lands near both ends of the tunnel, including certain lands of the plaintiff. The present action was begun by the plaintiff under section 12 of the ordinance above mentioned, for the purpose of contesting the validity of the assessment and to quiet plaintiff’s title to the said lands against the claims of the city of San Francisco thereunder. Judgment was given in favor of the defendant. The plaintiff appeals therefrom.,
An ordinance similar to the tunnel procedure ordinance of October 20, 1913, aforesaid, was under consideration by this court in
Mardis
v.
McCarthy,
1. The ordinance was adopted under the power conferred upon the city by chapter VIII of article VI of the charter. This chapter empowers the board of supervisors to order the construction of and construct a tunnel and levy the damage, cost, and expenses thereof upon private property “in the manner and under the procedure and powers in chapter II of this article provided for street work and street improvement. ’ ’ It further provides that the method of procedure in chapter II shall not be exclusive, but that the board of supervisors may adopt an ordinance “providing a method of procedure for such improvement, work, and assessment and for the ascertainment and payment of damages and for the manner in which protests against such assessments and damages awarded may be heard and determined, and for the manner *6 in which such assessment may be collected and paid,” and for fully and completely exercising the powers conferred by the section. In» said chapter II, after giving the city power to make street improvements, other provisions follow prescribing the procedure to be followed in exercising the power. An application of property owners to the board of public works must be made in order to start the proceeding, 1 ‘ except where otherwise provided.” The board must then pass a resolution of its intention to recommend the doing of the work and must recommend the same to the supervisors, before the improvement is ordered. The appellant insists that these provisions of chapter II are limitations upon the power therein conferred, and that by the reference aforesaid, in chapter VIII, they are carried into and become limitations upon the power to construct tunnels and also upon the power to adopt, by ordinance, the procedure to be observed in the construction of tunnels, that, consequently, such ordinance must also provide for an application of owners and a resolution and recommendation by the board of public works, as a condition precedent to ordering the tunnel construction, and that as this ordinance does not do so, it is void. To this we cannot agree. The provisions of chapter VIII differentiate clearly between methods of procedure and the grant of power, and between the grant of power to construct tunnels and the grant of power to provide the procedure therefor. The two grants are independent of each other. It is true that proceedings for assessing the cost of public improvements upon private property are to be strictly followed and that, as is often said, “the mode is the measure of the power,” so that in doing street work under chapter II the method of initiating the proceeding must be followed in order to make a valid exercise of the power there conferred. But to hold that the reference to chapter II, contained in chapter VIII, imports into the latter chapter all of the provisions for procedure provided in chapter II, as limitations upon the power conferred in chapter VIII, including the power to adopt an ordinance prescribing the procedure, would, in effect, entirely destroy the power given in chapter VIII to adopt a method of procedure,. Such an absurd result cannot be allowed unless positively necessary. Such a construction is not imperative. It is more reasonable to suppose that the reference in chapter VIII to the procedure and powers provided in chapter II for *7 street work had reference to procedure alone and did not incorporate such procedure into chapter VIII, as limitations upon the power to construct tunnels and to adopt ordinances of procedure therefor, but left the board of supervisors at liberty to adopt a procedure wholly different from that provided in chapter II. This we believe to be the true construction of the charter in this particular.
2. The resolution in question states that the public interest and convenience require the construction of the Twin Peaks tunnel “for public uses,” but do not specify or describe the particular public use or uses to which it is to be devoted. It appears from the evidence, however, that no way is provided for passage through the tunnel by persons traveling on foot or in vehicles, or otherwise than in street-cars. It is conceded by the respondents that as it exists it cannot be used except as a way upon which to lay tracks for street-ear lines and for the passage of persons through it while in such cars, and that no other use was intended. The charter provides that two or more street-ear lines, operated under different managements, may use a tunnel constructed under the power given in chapter VIII and that the city and county may use it for a municipal street-car line, either singly or jointly with another street-car line, but. that no exclusive right to its use 'by a street-car line shall ever be given. (Art. VI, e. VIII, sec. 5.) It also appears that since its completion the tunnel has been used exclusively as a passageway for cars on a branch of the street-car system operated by the city and county.
*8 The appellant contends that no assessment for the cost of a tunnel for such purposes can be made upon private property ; that such a railroad must be the property of a private corporation or of a municipal corporation acting in its proprietary capacity; that if it belongs to a private corporation the tunnel would not be for the public benefit, but would be for the benefit of such corporation, which is a purpose for which a special assessment upon private property cannot lawfully be made, while if the railroad belongs to the municipal corporation, the tunnel would he for the general benefit of the municipality and the expense thereof could lawfully be met in no other way than by a general ad valorem tax upon all property within the city.
It has been said that the power to levy a special assessment upon private property for public purposes “is not a power to tax property generally, founded upon the benefits supposed to be derived from the organization of a government for the protection of life, liberty, and property, but a power to tax specific property, founded upon the benefit supposed to be derived by the property itself from the expenditure of the tax in its immediate vicinity. Hence, property not benefited by the improvement cannot he subjected to the burden imposed for that purpose.”
(Taylor
v.
Palmer,

3. It is claimed that the charter confers no power upon the,city and county to make a tunnel, except in or under a public street, or under land belonging to it or in which it may have an easement, and that, as this tunnel runs in part through land which is not a public street and in which the city then had no easement and which it did not own at the time the proceeding was begun, the assessment was beyond the power given and is therefore invalid.
These provisions could have been adopted upon no other theory than that if the city and county did not already have the property necessary for the proposed tunnel or tunnels, it could acquire such property and order and carry on the construction of the tunnel in a single proceeding including both purposes. The phrases, “any other land of the city and county” and “in which and where the city and county may then have an easement” in section 1, must, in view of the subsequent provisions of the chapter, be taken to refer to any period of time antecedent to the actual construction of the tunnel, or, possibly, antecedent to the letting of the contract therefor or the beginning of the work thereon, and not to require that the city shall own the property or easement necessary for the tunnel before or at the time when the proceeding to construct it is initiated. Any other construction of section 1 would render the provisions of sections 2 and 3 inoperative and unnecessary so far as they authorize the combination of the two purposes in a single proceeding. These provisions, therefore, point the meaning of the language of section 1 as above stated. The several sections, when considered together, show an intention to authorize the construction of a tunnel through land to be acquired in a consolidated proceeding, including both the acquisition and the construction.
4. The proceedings included the acquisition, at a cost of $514,935, of a strip of land about ninety feet wide and one thousand nine hundred feet long, at the eastern end of the tunnel at the end of Market Street. Appellant claims that the assessment is void because this strip constitutes an extension of Market Street and because a strip of land ninety feet wide cannot be necessary for a tunnel only twenty-four feet wide in the clear, exclusive of the walls or casings. The only evidence to support this contention was the original resolution of intention and the testimony of a witness, who said he was a civil engineer, that he had examined the plans, and that it was not necessary to have the strip of land ninety feet wide in order to construct the tunnel as planned. The record shows that the strip in question was acquired because it was necessary and convenient for the construction of the tunnel. No mention is made therein of Market Street or of
*12
any extension thereof.
The procedure ordinance provides that the board of public works shall make and report to the supervisors plans for the tunnel, an estimate of the costs and expenses thereof, a map showing the assessment district proposed, with a statement of the damages to lands affected by the tunnel and the benefits to the lands in such assessment district. Thereupon there is to be a public hearing, upon notice, after which the supervisors may modify, confirm, or reject the report, or modify it and confirm it as modified. Elaborate plans were made by the board and reported to the supervisors. The required notice was given, protests were filed and there was a hearing of the matter: At that hearing the report was modified and confirmed as modified. This was the equivalent of a decision by the board of supervisors that the protests were not well fqunded; that all of the proceedings up to that point had been correctly taken, and that all the lands proposed to be taken were necessary for the construction of the proposed tunnel. This determination is presumed to be correct.
5. The next objection of the plaintiff is that the entire assessment is void because it appears upon its face that the *13 apportionment of the cost is not proportional or uniform. This objection is founded upon the facts that the assessment shows upon its face that certain lots included within the assessment districts are not assessed at all, and that of lots which plaintiff claims are similarly situated some are assessed at one-eighth of a cent per square foot, and others at a much higher rate, varying from one and three-quarters cents to three and one-half cents per _ square foot. No extrinsic evidence was given tending to prove that the lots not assessed were in fact benefited by the tunnel.
The provisions of the procedure ordinance show that the district and the lands to be assessed were not to be finally fixed in advance by the supervisors in the resolution of intention. It is the order of confirmation of the report of the board of public works, as modified by the supervisors upon the hearing of protests, that fixes the exact limits of the assessment district and the precise parcels of land to be assessed. The ordinance declares that the resolution of intention to order the construction of the tunnel must “specify the exterior boundaries of the district or districts of land to be benefited by such construction and to be assessed to pay the damages, costs, and expenses thereof.” (Section 2.) But this is not the final decision on the subject. Upon receiving this resolution, the board of public works, after first determining the amount of damages that will be sustained by persons claiming damages, must estimate the total amount of costs of construction, including the costs of acquiring the necessary land and the damages sustained, and assess the total sum “upon the several lots of land benefited within the district or, districts of assessment, so that each of the lots shall be assessed in accordance with its benefits caused by such tunnel construction.” (Section 5.)
There is a distinction between the power of the board making the assessment in cases -where the legislature has itself fixed the limits of the assessment district and designated the land which is benefited and which is to be assessed for the expense of a public improvement, and cases where a local legislative body has authority to levy the expenses upon a district to be fixed by itself and to determine what property is benefited and is to be assessed for the improvement. The ordinary case of a front-foot assessment is an example of the first alternative. There the legislature has declared what property shall be assessed, and its declaration is a determination that the property to be assessed is also the property
*15
benefited. In a case of that character the board which levies the assessment cannot depart from the legislative determination, and if it omits from the assessment any parcel of the land which the legislature has thus declared is benefited and is to be assessed for the improvement, the assessment is void.
(People
v.
Lynch,
There is a statement in
Davies
v.
Los Angeles,
Section 12 of the ordinance provides that any property owner aggrieved at any assessment levied may commence an *17 action to contest his assessment, levied under the terms of the ordinance, but that such action must be begun within thirty days after the adoption of the resolution of the supervisors finally modifying and confirming the assessment reported by the board of public works. This action was begun under that authority. The plaintiff insists that in such an action he may review all the proceedings of the supervisors, including its determination as to the property benefited and the amount of benefits to be assessed.
Even if this were conceded, it must be also conceded that the determination of the supervisors is at least prima facie correct, and that it could not be set aside except upon evidence showing that the decision was not sustained by the facts existing. No evidence was offered or given to show that the particular lots not assessed for the improvement were in fact benefited thereby. In the absence of such evidence it is obvious that the decision of the supervisors could not be declared invalid.
The reasons above given also answer the objection urged in this connection that the assessment was not made according to the benefits. The determination of the supervisors is conclusive on that subject also. We find no ground on which these objections can be sustained.

7. Plaintiff urges that there was error at the trial in refusing to admit certain evidence offered by him.
A member of the board of public works was asked to state what rule that board adopted in apportioning the benefits in the district; whether he, personally, went upon the land to make the assessment; whether he took part in making the estimate of the benefits; whether the board had the land viewed by any person for its information, and what information the board had as to such benefits and from whom it' was derived. He was then asked to state why a different rate of assessment was placed upon different blocks which, it was claimed, were not assessed at the same amount. These questions all related to the action of the board of public works in
*19
making up its estimate prior to the filing of its report with the supervisors.
The judgment is affirmed.
Olney, J., Wilbur, J., Lennon, J., Lawlor, J., and Angellotti, C. J., concurred.
Rehearing denied.
All the Justices concurred.
