The Commissioner of Natural Resources and the Director of Marine Fisheries bring this bill in equity against S. Volpe & Co., Inc., a corporation of Massachusetts, to enjoin the defendant “from placing any further fill on Broad Marsh in the Town of Wareham” in violation of a condition imposed by the commissioner, and to order the defendant “to remove all fill placed on and in Broad Marsh” in violation of that condition. After a hearing a final decree was entered in which the defendant was enjoined and ordered accordingly. The defendant appealed. The judge made a report of the material facts found by him, from which, unless otherwise stated, are taken the facts in this opinion. G. L. c. 214, § 23 (as amended through St. 1947, c. 365, § 2). The evidence is reported.
Broad Marsh is located westerly of Sunset Cove off Onset Bay in the coastal waters of Wareham. A tidal creek known as Broad Marsh Creek flows through the northerly portion of the marsh into Squaw’s Hole, the northwestern end of Sunset Cove. The tide flows through mosquito control ditches in the marsh, at times flooding it.
In 1960 the defendant acquired a parcel of land containing 49.4 acres within Broad Marsh, which covers a total of 78 acres more or less. On October 3,1963, as alleged in the bill, admitted in the answer, and found by the judge, the defendant gave written notice pursuant to G. L. c. 130, § 27A (inserted by St. 1963, c. 426), 1 of “its intention to dredge a channel and basin into said Broad Marsh in connection with a marina to be constructed adjacent thereto at some future date.” This finding is accurate as far as it goes, but, as we ourselves find, the channel, basin, and *106 marina were incidental to the defendant’s main project of filling the marsh for the construction of houses with water rights for boating.
On October 9,1963, the board of selectmen of Wareham, pursuant to § 27A, conducted a hearing on the defendant’s application. At the hearing the plaintiffs requested from the defendant a detailed plan of the proposed work. On October 21 this was furnished. Thereafter the director notified the defendant “that in the interest of protecting marine fisheries and maintaining the ecological components of this estuarine complex in their present protective form” “no fill of any type be placed upon that area known as Broad Marsh.” The director did not, and does not now, object to the dredging of the channel and basin.
The defendant disputed that the condition contained in this notice was authorized by § 27A, and ignoring the director’s notification, commenced filling Broad Marsh and continued doing so until temporarily enjoined on January 20, 1964. The local authorities, the State Department of Public Works, with reference to G. L. c. 91, § 30, § 30A (inserted by St. 1950, c. 214), and the Secretary of the Army acting through the Corps of Engineers under 33 U. S. C. § 403 (1958) have all approved the project.
The trial judge concluded (A) that the restriction of “no fill” is a condition authorized by § 27A; (B) that Broad Marsh is a “saltmarsh” necessary to preserve and protect marine fisheries; (C) that § 27A is valid; and (D) that the “condition” imposed is not an unlawful taking entitling the defendant to compensation.
In support of his general findings (A) and (B) the judge found the following: 1 ‘ The important biological significance of Broad Marsh is its nutrient contribution to the shellfish and other fishery resources of the Sunset Cove - Onset Bay area. The two most conspicuous plants of Broad Marsh are the cordgrasses, Spartina Patens and Spartina Alterni-flora. As these plants die and decay, large amounts of phosphates and nitrates are released into the adjacent waters. These nutrients are essential for the growth of *107 microscopic plants and other micro-organisms, which in turn are the primary source of nutrition for shellfish as well as the young fish and crustaceans.” “ [T]he nutrients derived from Broad Marsh, and, in particular, the portion thereof intended to be filled by the . . . [defendant], play an important and integral part in sustaining the life of the shellfish and finfish in the areas adjacent thereto. . . . Without these nutrients untoward damage will result to the marine fisheries which depend on the productivity of the adjacent marsh for their sustenance.” We cannot pronounce these findings plainly wrong. Two experts for the plaintiff have provided supporting testimony.
As to the trial judge’s finding (C), the protection of marine fisheries is undoubtedly a public purpose for which § 27A was properly enacted. The Legislature clearly has power to protect and preserve the fish and game of the Commonwealth.
Commonwealth
v.
Gilbert,
This is not the whole matter, however. A crucial issue is whether, notwithstanding the meritorious character of the regulation, there has been such a deprivation of the practical uses of a landowner’s property as to be the equivalent of a taking without compensation.
Mile Rd. Corp.
v.
Boston,
The trial judge recognized the existence of this question, but the narrow finding of the scope of the project above referred to led to other findings which are inapplicable to the realities of the case and must be disregarded as lacldng support in the evidence. Thus he found that the plaintiffs have not placed an absolute restraint on the defendant in *108 imposing the condition prohibiting filling Broad Marsh; that the condition imposed relates only to the filling of Broad Marsh and does not completely restrain the defendant’s commercial enterprise, which may be conducted and completed by alternative methods; that the defendant is not prevented from dredging and transporting the dredged material to any location other than Broad Marsh, thus causing no damage to marine fisheries; that the defendant may dredge a greater distance through Broad Marsh to upland property which it owns and where no significant nutrient values necessary to protect marine fisheries are extant; that the condition imposed by the director is reasonable; and that “ [s]imply stated, he desires the . . . [defendant] to locate its proposed marina, yacht club and recreational center shoreward of Broad Marsh and to place no fill on the said marsh.”
The question is analogous to that which arises when the validity of a zoning ordinance or by-law is considered. Whether there is a reasonable interference with a landowner’s rights undertaken in the exercise of the police power for the public benefit or a deprivation of private property without compensation often depends upon the facts of the particular case.
Pittsfield
v.
Oleksak,
Two zoning cases in other jurisdictions may have perti-nency. In
Morris County Land Improvement Co.
v.
Township of Parsippany-Troy Hills,
40 N. J. 539, the municipality had placed the plaintiff’s swamp property in a floodwater detention basin. At pages 556-557, it was said, “We
*109
cannot agree with the trial court’s thesis that, despite the prime public purpose of the zone regulations, they are valid because they represent a reasonable local exercise of the police power in view of the nature of the area and because the presumption of validity was not overcome. In our opinion the provisions are clearly far too restrictive and as such are constitutionally unreasonable and confiscatory. ” In
Dooley
v.
Town Plan & Zoning Commn.
S. Volpe, the president, treasurer, and principal stockholder of the defendant, testified that the project he had in contemplation could not be carried out without filling the marsh as he proposed; that if the marsh were not to be filled no use, residential or commercial, could be made of the area owned by the defendant; that there was no point to the dredging if he could not fill the area; and that unless he could dredge the channel and fill the portion owned by the defendant on Broad Marsh the land was of no value to him.
While we find without hesitation that the project was as testified by him, we are in no position also to find whether there has been such a deprivation of the practical uses of the marsh as to be the equivalent of a taking without compensation. A finding one way or the other on this issue is essential to a proper disposition of the case.
The plaintiffs argue as though all that need be done is to demonstrate a public purpose and then no regulation in the interests of conservation can be too extreme. We quote an example from their brief: “if the decision of the trial judge is not upheld in this case, where the evidence is so overwhelming that the marsh . . . does contribute substantially to the ecological system necessary to the sustenance of shellfish and fin fish, the statute will be emasculated and our efforts to conserve our natural resources will have received a severe setback.” An unrecognized taking in the
*111
guise of regulation is worse than confiscation. As the New York Court of Appeals said in the
Arverne
case,
supra,
In this conflict between the ecological and the constitutional, it is plain that neither is to be consumed by the other. It is the duty of the department of conservation to look after the interests of the former, and it is the duty of the courts to stand guard over constitutional rights.
In summary, our views are that the finding that Broad Marsh is a “saltmarsh” necessary to preserve and protect marine fisheries is not plainly wrong; that, considered apart from the taldng issue, the rulings that the prohibition of filling the marsh is a condition authorized by § 27A, and that § 27A is valid, are correct as upholding a valid public purpose; and that whether the defendant is the uncompensated victim of a taking invalid without compensation depends upon further findings as to what uses the marshland may still be put and possibly upon other issues which have not been argued and which are enumerated below.
The final decree is reversed. The case is remanded for the following purposes:
First, for the taking of further evidence and for further findings on the following matters:
1. The portions, if any, of the 49.4 acres (the locus) which the owner desires to improve below the line of mean high water (see
Commonwealth
v.
Roxbury,
2. The uses which can be made of the locus in its natural state (a) independently of other land of the owner in the area; (b) in conjunction with other land of the owner.
*112 3. The assessed value of the locus for each of the five years, 1960 to 1964, inclusive.
4. The cost of the locus to the defendant.
5. The present fair market value of the locus (a) subject to the limitations imposed by the Commissioner; (b) free of such limitations.
6. The estimated cost of the improvements proposed by the defendant.
7. Any relevant rules and regulations prescribed by the Director of Marine Fisheries.
8. Any relevant by-laws (including zoning provisions) or regulations of the town of Wareham.
Second, for further hearings to develop any revelant evidence on each of the following issues, none of which has been argued and as to which we express no opinion. Briefs and oral arguments should be directed at least to such issues upon any subsequent appeal to this court.
A. Would the Commonwealth, by the imposition of the proposed restriction, take property without just compensation, if there is no substantial possible use of the locus while subject to the proposed restriction which will yield to the owner of the locus a fair return (1) upon the amount of his investment in the locus, or (2) upon what would be the fair market value of the locus free of the restriction?
B. If it is contended that the land, if subject to the proposed restriction, may be profitably used in connection with other land, is this relevant, and, if so, to what extent?
C. Is it relevant to question A or B that the locus is not suitable in its present state for residential or commercial use?
D. Is it relevant to questions A and B that the proposed filling, at least in part, will change coastal marshland, subject at times to tidal flow into upland?
E. What, if any, is the effect and relevance of the colonial ordinance on the case at bar and to what extent does the ordinance relate to matters other than navigation near and upon the locus?
So ordered.
Notes
Section 27A provides in part: “No person shall remove, fill or dredge any bank, flat, marsh, meadow or swamp bordering on coastal waters without written notice of his intention to so remove, fill or dredge to the board of selectmen in a town . . ., to the state department of public works, and to the director of marine fisheries. . . . The selectmen . . . shall hold a hearing on said proposal .... If the area on which the proposed work is to be done contains shellfish or is necessary to protect marine fisheries, the said director may impose such conditions on said proposed work as he may determine necessary to protect such shellfish or marine fisheries, and work shall be done subject thereto. . . . [T]he superior court shall have jurisdiction in equity to restrain "a continuing violation of this section. ...”
