This is a bill in equity by thirteen of the inhabitants and taxpayers of the city of Boston to enjoin payment from the treasury of the award made to abutters under an order of the street commissioners establishing building lines on Province Street, a highway within the municipality. G. L c. 40, § 53. St. 1885, c. 178, §§ 1, 2, 3. And the case is here on the report of a single justice whose findings of fact on unreported evidence are conclusive. Armstrong v. Orler, 220 Mass. 112.
It appears that on July 11, 1922, the mayor transmitted a message to the city council stating that the “ importance of opening the block bounded by Tremont, Washington, School and Bromfield streets, both for the purpose of providing a highway for public travel and for the development of realty located within this lot of land before prohibitive realty development has been created makes it essential that action be taken at once and I accordingly recommend the adoption of the accompanying order, providing for the establishment of a building line on Province Street, between School Street and Bromfield Street.”
*422The city council thereupon on August 15, 1922, passed an order approved by the mayor, that “ the sum of $250,000 be and the same is hereby appropriated for the establishment of a building line, on Province St., between School Street and Bromfield, and that to meet said appropriation the city treasurer be authorized to issue, from time to time, upon the request of the mayor, bonds or certificates of indebtedness of the city to said amount.” It is found that on August 14, 1922, the borrowing capacity of the city was $382,050.65, and the order did not violate the prohibition of St. 1885, c. 178, §§ 1,2,3, fimiting under certain conditions the borrowing capacity of the city.
The board of street commissioners, acting under statutory authority, issued on August 17, 1922, a notice, that the board is of opinion “ that, in said city public convenience and necessity require that building lines be established on the northwesterly and southeasterly sides of Province street Boston Proper, between School and Bromfield streets, substantially as shown on a plan in the office of this board, that it intends to pass an order for making said building lines, and that it appoints 11 o’clock a.m. August 31, 1922, and the office of this board as the time and place for a public hearing in the matter.” St. 1821, c. 110, §§ 5-8, 11-15. St. 1854, c. 448. St. 1870, c. 337. St. 1893, c. 462. St. 1906, c. 393, §§ 1, 2, as amended by St. 1913, c. 536, § 2, and Spec. St. 1917, c. 318. St. 1893, c. 462, accepted by the city October 28, 1893, now G. L. c. 82, § 37, with prior amendments. Brimmer v. Boston, 102 Mass. 19, 22. A copy of this plan is part of the record.
The board on October 13, 1922, passed an order, approved by the mayor, which after recitals of the giving of notice, and that a copy of the order had been published in two daily newspapers of the city, and that a public hearing in accordance with the notice had been given, reads as follows: “ that building lines be, under the provisions of chapter 462 of the Acts of 1893 and the acts in amendment or addition thereto, established on Province Street, Boston Proper, between Bromfield Street and School Street, as follows:
“On the southeasterly side of said Province street, between *423Province court and the southwesterly boundary line of the property of the Boston Five Cents Savings Bank, substantially parallel with and distant approximately thirty-three (33) feet from the southeasterly exterior side line of said Province street.
“ For one year from the date of this order: on the southeasterly side of said Province street, between Bromfield street and Province court, substantially parallel with and distant approximately thirty-six (36) feet from the southeasterly exterior side line of said Province street.
“ For one year from the date of this order: On the southeasterly side of said Province street, between the southwesterly boundary line of the property of the Boston Five Cents Savings Bank and School street, substantially parallel with and distant approximately thirty-four (34) feet from the southeasterly exterior side line of said Province street.
“ For one year from the date of this order: on the northwesterly side of said Province street, between Bromfield and School streets, substantially parallel with and distant approximately fifty (50) feet from the building lines herein-before established on the southeasterly side of said street.
" Said building lines are shown on a plan marked ' City of Boston Province St. Boston Proper August 7,1922 . . . ’ and on file in the office of the Street Laying-Out Department.
“ And this Board further orders that existing buildings, steps, windows, porticos and other usual projections appurtenant thereto, as far as they lie between the building lines herein established and the present exterior side lines of said Province street, may remain as they are at the date of this order, intending hereby to sanction all existing projections over said building lines until the said projections shall have been removed therefrom or until said Province street is ordered relocated or widened by the City of Boston by and through its duly authorized officials under authority of the statutes in such cases made and provided.”
On its face this order designated a continuous building line on each side of Province Street. The fine on the southeasterly side crossed the land of the Olympia Theatre Company and of the Massachusetts General Hospital, who were *424awarded damages aggregating $175,000 on the basis of a permanent line, while the remaining abutters on that side, and on the northwesterly side, were awarded only nominal damages, because the line as to their lands was to be established only for one year from the date of the order. It is found that, if the temporary lines had been permanent, the entire cost of the “ development ” would have been at least “ $1,000,000.” But it is unnecessary for our decision to determine whether the underlying purpose of the commissioners, as the plaintiffs contend, was to evade the provisions of St. 1885, c. 178, § § 1, 2, 3. The parties agreed before the single justice, “ that there was no bad faith on the part of the commissioners.” See Browne v. Boston, 179 Mass. 321, 322.
The locating or establishment of building lines as prescribed by the order, delimited the estates of the abutters so that they should conform to the street lines shown by the plan, even if under G. L. c. 82, § 37, “ existing buildings, steps, windows, porticos and other usual projections appurtenant thereto, as far as they he between the building lines herein established and the present existing side lines of said Province street, may remain as they are at the date of this order, intending hereby to sanction all existing projections over said building lines until the said projections shall have been removed therefrom or until Province street is ordered relocated or widened by the ” city under the authority conferred by statute to relocate or widen highways. See Tyler v. Hudson, 147 Mass. 609. The terms of the order are explicit. It contained the adjudication of the commissioners, that public convenience and necessity required the establishment of the lines. It stated the intention of the board to establish them, and directed notice to the abutters of the time and place where the board would proceed to lay out the lines, and hear parties who were entitled to be heard in the matter of damages, and betterment assessments. The board however determined that “ There are no betterments; damages are as follows,” and the names and amounts awarded to the abutters are annexed.
It is plain, that the order operated, and was intended to *425operate, as a taking of private property for public use under the power of eminent domain delegated by the Legislature. Dwight v. Springfield, 6 Gray, 442, 443. Fuller v. Mayor & Aldermen of Springfield, 123 Mass. 289, 290, 291. Murray v. Norfolk, 149 Mass. 328. Morse v. Stocker, 1 Allen, 150, 157. Dorgan v. Boston, 12 Allen, 223. Durgin v. Minot, 203 Mass. 26, 28. Comiskey v. Lynn, 226 Mass. 210, 212. Zeo v. City Council of Springfield, 241 Mass. 340. Eubank v. Richmond, 226 U. S. 137, 144, 145. G. L. c. 79, § 1. G. L. c. 82, § 37. St. 1893, c. 462. And as private property cannot be taken except for a public use, no more property is to be condemned, than the public use requires. Simonds v. Walker, 100 Mass. 112, 113. Lowell v. Boston, 111 Mass. 454, 463. Doon v. Natick, 171 Mass. 228, 230. The procedure of the commissioners accordingly must rest on the statute, and they had no authority to appropriate private property for use as a highway except as therein provided. Hellen v. Medford, 188 Mass. 42. See Weeks v. Grace, 194 Mass. 296, 298.
By G. L. c. 82, § 37, a building line can be established and discontinued in the manner prescribed for the laying out and discontinuance of highways and town ways. The Legislature has enacted special statutes providing for the taking of existing easements, as well as taking in fee of land, of which St. 1913, c. 700, an act to provide an additional water supply for the cities of Salem and Beverly, and the metropolitan water act, St. 1895, c. 489, are sufficient examples. And by Spec. St. 1919, c. 115, the cities of Lynn, Peabody, Salem and Beverly and the town of Danvers, which by St. 1901, c. 508, and St. 1913, cc. 698, 699, and 700, had been authorized to take water from the Ipswich River, were “ further authorized, in case of emergency, to take water from said river or its tributaries during the months from June to November, inclusive, in the years nineteen hundred and nineteen, nineteen hundred and twenty and nineteen hundred and twenty-one, or any of said years, in quantities not exceeding those which may be taken from December to May, inclusive . . . whenever, in the opinion of the State department of health, the taking of water during the months *426aforesaid in the years mentioned, ... is necessary to provide an adequate water supply for the cities and town herein mentioned . . . .” See also St. 1902, c. 351. But our attention has not been called to any general statute or law for the laying out, or discontinuance of highways, which empowered the commissioners to lay out, or discontinue a public way for the period of one year. If they could not lay out, and take land for a highway which was to exist for one year only, they could not impose building lines for one year. The taking does not purport to be in fee, and the abutters were entitled to compensation for all damages suffered by a perpetual easement imposed for the public use. Dingley v. Boston, 100 Mass. 544, 560. The statute contemplates that the taking of the same land for a highway shall not be at recurrent intervals until the way has been legally discontinued, and that damages for each taking shall be measured by the duration of each successive condemnation. Boston v. Richardson, 13 Allen, 146, 160. Dingley v. Boston, 100 Mass. 544, 560. Pierce v. Drew, 136 Mass. 75. Page v. O’Toole, 144 Mass. 303. Titus v. Boston, 161 Mass. 209. Doon v. Natick, 171 Mass. 228, 230. Winnisimmet Co. v. Grueby, 209 Mass. 1. G. L. c. 79, § 1.
It is contended by the defendants, that, even if the temporary lines were unauthorized, the commissioners established several building lines, and the permanent line was within the statute. The notice of the commissioners was for a hearing on the establishment of building lines “ shown on a plan in the office of this board.” The message of the mayor referred to, and the appropriation of the city council provided, “ for the establishment of a building line on Province Street, between School Street and Bromfield Street.” The order of the board however divides the southeasterly line into two distinct portions, so that in the taking one part covers the estates of the realty company and the hospital, while the other part covered the estates of the remaining abutters on that side. The appropriation manifestly does not provide for two lines on the southeasterly side of Province Street. The order of the commissioners cannot be divided. It is not capable of a double construction which *427sustains the permanent taking, and disregards the taking for one year. Preston v. Newton, 213 Mass. 483, 485, 486. The valid and invalid parts moreover are so mutually connected with, and dependent upon each other, as to warrant the conclusion in substance of the single justice, that the board intended them as a whole, and he rightly ruled that if all could not be given effect, the entire layout must fail. Warren v. Mayor and Aldermen of Charlestown, 2 Gray, 84, 98, 99.
It follows, that a decree for the plaintiffs is to be entered with costs, enjoining the expenditure of the appropriation for any of the purposes specified in the order of the street commissioners, the details of which are to be settled in the county court. Welch v. Emerson, 206 Mass. 129.
Ordered accordingly.
