Before GILLETTE, P.J., and ROBERTS and YOUNG, JJ.
YOUNG, Judge.
Petitioner seeks review of an order of the Land Use Board of Appeals (LUBA) affirming approval by the Monmouth City Council (City) of a minor partition of land. We reverse.
This case arises from an application by two Monmouth property owners for partition of their two parcels of land into three parcels. Petitioner's property is adjacent to one of the parcels for which partitioning was sought. The City's Planning Commission staff recommended approval of the partitioning upon the condition that interior utility easements and sidewalks be provided. After a public hearing the Planning Commission denied the application without indicating its reasons for so doing. The applicants appealed to the City Council, which held another public hearing, after which it approved the partitioning as submitted. Petitioner sought review by LUBA, which affirmed the city's action.
We first address petitioner's contention that LUBA had no jurisdiction to review the City's action because the statute creating the Land Use Board of Appeals, Or. Laws 1979, Ch. 772, §§ 1-6a, violates the doctrine of separation of powers, Article III, § 1 and Article VII (Amended), § 1, of the Oregon Constitution.[1] Petitioner does *502 not claim that administrative agencies may never exercise judicial functions, but argues rather that those functions must be ancillary to the exercise of administrative duties within the agency. Petitioner argues that LUBA is an administrative agency with only judicial functions and that this violates the constitution.
LUBA is empowered by Or. Laws 1979, ch. 772, § 2a(1) to "conduct review proceedings upon petitions filed in the manner prescribed * * *." Its only function is to review land use decisions. It is this delegation of solely adjudicatory functions to an individual agency which petitioner contends is unconstitutional.
The doctrine of separation of powers has never been held in this state to prevent the exercise of judicial powers by administrative agencies. See, e.g., In re Willow Creek, 74 Or. 592, 144 P. 505, 146 P. 475 (1915); Evanhoff v. State Industrial Acc. Com., 78 Or. 503, 154 P. 106 (1915); Mallatt v. Luihn et al., 206 Or. 678, 294 P.2d 871 (1956); Mazama Tim. v. Lane Air Poll Auth., 17 Or. App. 288, 521 P.2d 1315 (1974). As noted in In re Willow Creek, supra, 74 Or. at 612, 144 P. 505:
"The separation of the powers, both state and national, has not been complete. The practical necessities of efficient government prevent a complete defined division. It has been necessary to vest in each department certain powers which primarily should not belong to it. * * * In many respects these acts provide for the performance of duties by administrative boards judicial in their nature or quasi judicial."
Delegation of adjudicatory powers to administrative agencies has been upheld in this state where judicial review is provided at some stage of the proceeding. See Mallatt v. Luihn et al., supra; Mazama Tim. v. Lane Air Poll. Auth., supra; cf., Evanhoff v. State Industrial Acc. Com., supra. This is consistent with the interpretation of the separation of powers doctrine adopted by federal courts. See Phillips v. Commissioner of Internal Revenue, 283 U.S. 589, 51 S.Ct. 608, 75 L.Ed. 1289 (1930); Sunshine Anthracite Coal Co. v. Adkins, 310 U.S. 381, 60 S.Ct. 907, 84 L.Ed. 1263 (1940). Review of LUBA decisions by this court is provided in Or. Laws 1979, ch. 772, § 6a.
We do not believe that the constitutionality of LUBA depends upon whether it was created as a separate agency or as part of another agency, such as the Department of Land Conservation and Development. The adjudicatory functions carried out by LUBA are ancillary to an administrative objective: the regulation of land use in this state. Whether the legislature creates a single agency or numerous agencies to accomplish this goal is unimportant. The establishment of LUBA did not violate the doctrine of separation of powers as expressed in Article III, § 1 or Article VII (Amended), § 1 of the Oregon Constitution.
On the merits, petitioner assigns as error LUBA's determination that the City's decision was supported by adequate written findings. The City's decision was made at the City Council hearing by an oral vote of the members. A letter was then sent to the applicants by the Mayor indicating that the partition had been approved. The letter summarized the evidence presented by the proponents and the opponents of the partition, and concluded:
"Because your partitioning would meet the area and frontage requirements of the zoning ordinance, its denial by the Planning Commission was reversed and the partitioning was approved by the City Council."
The statement that the partitioning would meet the frontage and square footage requirements of the zoning ordinance is the only "finding" made. Petitioner contends that the City had discretion to deny *503 the partitioning application even if the frontage and square footage requirements of the ordinance were met, because the "purposes" section of the zoning ordinance[2] provides standards for application in land use decisions by the City. Petitioner contends that it was error for the City to fail to consider and make findings regarding the application of those standards.
LUBA found that the purposes section of the ordinance was not necessarily intended to provide standards for decision-making under the ordinance, citing Anderson v. Peden, 284 Or. 313, 587 P.2d 59 (1978), and deferred to what it considered to be the City's interpretation of its own ordinance, i.e., that the purposes were not intended to serve as standards for decision-making. LUBA concluded that the frontage and square footage requirements of the ordinance were the only requirements for allowance of a partition and that once those requirements were shown to have been met, the City had no discretion in granting the partition. From that conclusion it followed that the finding made by the city was adequate to support the granting of the partition.
We might be inclined to agree with LUBA's reasoning in this matter were it not for the statements made by counsel for the City at the oral argument of this case before this court.[3] The City then indicated that its position was always that it had discretion to consider factors other than the frontage and square footage requirements in deciding whether to grant a partition, but that in this case the City found those requirements were all they were required to consider. This leaves us somewhat confused as to the City's interpretation of its ordinance.
Once the comprehensive plan and implementing ordinances of a local government unit have been acknowledged by the Land Conservation and Development Commission, see ORS 197.251, land use decisions are to be governed by the criteria contained in that plan and those ordinances. ORS 197.275(2); Neuberger v. City of Portland, 288 Or. 155, 603 P.2d 771 (1979). The City of Monmouth has received acknowledgment of its comprehensive plan and zoning ordinances and, therefore, the criteria for the granting of a partition are to be supplied by reference to its comprehensive plan and zoning ordinances.
We agree with LUBA that the City, in making a land use decision, is not required to consider factors set forth in the purposes section of the ordinance if that was not the intent of the ordinance. However, whatever criteria are applicable to the request for a partition of land must be applied to all such applications. LUBA's decision was based, at least in part, on deference to what it understood to be the City's own interpretation of its ordinance. The City now indicates that that is not and has not been its interpretation of that ordinance. By indicating that it has discretion to consider other factors in deciding whether to grant a partition of land, the City has, in effect, admitted that it did not make findings on all criteria made relevant to the decision by the proceedings before it. Cf. Hillcrest Vineyard v. Bd. of Comm. Douglas Co., 45 Or. App. 285, 608 P.2d 201 (1980). On the basis of this admission, we conclude that LUBA was in error in finding that the *504 City's order was supported by adequate findings. We reverse and remand to LUBA with instructions to enter an order consistent with this opinion.[4]
Reversed and remanded with instructions.
