SISTERS OF BON SECOURS HOSPITAL
v.
CITY OF GROSSE POINTE.
Docket No. 1,195.
Michigan Court of Appeals.
Decided November 27, 1967.
Neil D. Hayes (Chris M. Youngjohn, of counsel), for plaintiff.
Charles H. King, for defendant city.
Arthur M. Hoffeins, for intervenors.
J.H. GILLIS, P.J.
Plaintiff is a nonprofit corporation operating a hospital within the limits of the city of Grosse Pointe. The history of the hospital dates back to 1925 when a tract of land was obtained and a nursing home founded thereon. In 1942 the capacity of the nursing home was increased to approximately 35 beds and in 1944, upon the organizing of a medical staff, the nursing home gave way to a general hospital operation under the name of Bon Secours Hospital.
*345 Until 1951 the area in which the hospital was located was zoned residence B, wherein hospitals were a permitted use.[1] In 1951, the city enacted section 3.12 of Ordinance No 96,[2] which prohibited hospitals (and other uses enumerated) in the area of the city lying south of Kercheval avenue. The residence B *346 classification continued on either side of Kercheval avenue but with the B district to the south subject to the additional conditions imposed by section 3.12.
At the time of enactment of section 3.12, Bon Secours, located to the south of Kercheval, was the only hospital in the city. From 1951 until the present time, Bon Secours continued in existence according to the cited ordinances as a nonconforming use. In 1954 an addition to the hospital brought it to its present capacity of 160 beds.
Throughout the development of Bon Secours, its building height was governed by Grosse Pointe Ordinance No 96, § 6.5 which provided as follows:
"In a residence B district no building shall exceed three stories or 50 feet in height, except that buildings or portions of buildings not used for dwelling purposes and which in the aggregate do not occupy more than 10 per cent of the area of the lot may be erected to a greater height, provided that no portion of such higher building shall be nearer to a side or rear lot line than one third of its height."
On January 21, 1963 the city adopted Ordinance No 112, § 3.15, which amended the above section 6.5. The amendatory section provided that no building shall be erected within the city to a height greater than 3 stories or 36 feet above grade.[3] Upon the adoption of this ordinance, Bon Secours became a nonconforming use as to height as well as to location.
*347 In May, 1956, the hospital purchased a strip of land to the south of the hospital building approximately 83 feet wide by 785 feet in length. The purpose of this acquisition, as testified to by plaintiff's witnesses, was to provide ample off-street parking for hospital patients, visitors and staff. Section 3.11 (c) (2) was adopted in March of 1957 to regulate parking facilities for buildings other than dwellings.[4] The pertinent paragraph provides:
"For hospitals and welfare institutions, at least 1 parking space for each patient bed and at least 1 parking space for each 5 staff persons."
In connection with its proposed addition, Bon Secours petitioned the city in 1963 for the third time to use its 83-by-785-foot strip for off-street parking. This petition was denied.
One other portion of Ordinance No 96 is material here. On January 21, 1963 the city amended section 3.1 to read as follows:
"Except as hereinafter provided, no building or premises or part thereof shall be used, altered, constructed or reconstructed except in conformity with the provisions of this ordinance which apply to the district in which it is located. However, any lawful nonconforming use existing at the time of passage of this ordinance may be continued provided that the building or premises involved shall neither be structurally altered nor enlarged unless such altered or enlarged part and the use thereof shall both conform to the provisions of this ordinance for the district in which it is located and shall receive specific prior approval of the city council. Such approval *348 of the city council shall be given only if the council determines that the proposed alteration or enlargement is not likely to produce any undue public health or safety hazard and is in general conformity with the character of the neighborhood involved. No nonconforming use if discontinued for more than 1 year or changed to a use permitted in the district in which it is located shall be resumed or changed back to a nonconforming use."
Bon Secours brought this action for declaratory relief challenging the constitutionality of the ordinances as being unreasonable and arbitrary and further that the ordinances as applied deprive plaintiff of its property without due process of law. The circuit judge declared the ordinances unconstitutional and the city takes this appeal in which neighboring landowners have appeared as intervenors.
Before proceeding to the legal issues presented herein, it will be helpful to outline the obstacles standing in the way of Bon Secours' proposed addition: (1) by the ordinance of 1951 (section 3.12) the hospital was made a nonconforming use; (2) by ordinance section 3.1 of 1963 a nonconforming use cannot be structurally altered or enlarged unless other ordinances are complied with and prior approval of counsel secured; (3) ordinance section 3.11 (c) (2) of March, 1957, requires 1 parking space for each bed, which would not be available to the hospital if it expanded to 320 beds unless its 785-foot strip of land could be used for parking; (4) the proposed parking strip is zoned residential B and was so zoned when acquired by the hospital; and (5) the contemplated addition would exceed the height limitation imposed by section 3.15 (January, 1963).
The argument addressed to the validity of the Kercheval line presents 2 theories which, so far as we are able to determine, are questions of first impression in this State. These are: (1) that a zoning *349 ordinance whose practical effect is to totally exclude a hospital from the community is invalid; and (2) that a city has no power to vary the uses within 1 single use classification.
There is some authority for both of these propositions. As to the first, the case nearest in point is Roman Catholic Archbishop of Detroit v. Village of Orchard Lake (1952), 333 Mich 389. In that case schools and churches were prohibited in all but 3 zones which comprised but 10% of the area of the defendant village. Under the facts and circumstances of the development of the community, the effect was a total exclusion of churches and schools from the village. The Court held the ordinance invalid as not bearing a substantial relationship to the public health, safety, morals or the general welfare of the community.
Likewise, the Supreme Court has expressed its displeasure with single district zoning plans (Gundersen v. Village of Bingham Farms [1964], 372 Mich 352); has struck down ordinances prohibiting legitimate enterprises anywhere in the community, such as billboards (Wolverine Sign Works v. City of Bloomfield Hills [1937], 279 Mich 205), drive-in theaters (Bzovi v. City of Livonia [1957], 350 Mich 489), and trailer parks (Gust v. Township of Canton [1955], 342 Mich 436).
The gist of these rulings is that legitimate land uses may not be prohibited unless the prohibition bears a real and substantial relationship to public health, safety, morals, or the general welfare of the community. While initially the ordinances were clothed with a presumption of validity, in all the above cases that presumption was overcome by a showing of no relationship between the ordinance and objects of the police power when viewed in light of existing community developments. Archbishop, *350 supra, is an exception in that no presumption of validity existed as to the exclusion of schools and churches because of provisions contained in the Michigan Constitution of 1908 (see Archbishop, supra, at p 394).[5]
The present case, however, is not a total exclusion case in the sense of no claimed relationship to public health, safety, morals or welfare. As the city claims, the community is a developed one, and hospitals are permitted north of Kercheval where various small, developed parcels are available which conceivably might be used for hospital purposes.
The second of these arguments we have referred to, that is, uniformity within district classifications, is based on the enabling statute which provides in section 1[6] that cities and villages may divide their community into use districts and that regulations may be imposed for each district. Plaintiff's argument is that the defendant city has no authority to disregard district lines by imposing the blanket "south of Kercheval" ban. To be sure the B district south of Kercheval is the same as the B district north of Kercheval but for the superimposition of the amendatory ordinance in question. While the argument is appealing and finds support in at least one recognized text,[7] and Michigan Supreme Court *351 decision,[8] it borders too closely on a mere labeling, to our minds, to base our decision on this premise.
Rather, we proceed to the argument (certainly one much more familiar to our courts) that the south of Kercheval ban bears no substantial relation to the health, safety, morals or welfare of the community. This is likewise the basis of the findings made by the trial judge:
"There is certainly no showing in this record  in fact, the testimony would seem to indicate to the contrary  that not only is there no relation to the public health, safety, morals or general welfare of this community served by the passage of the ordinance in question but that in effect the enforcement of this ordinance might have a serious adverse effect on the public health of the defendant city and its neighboring communities."
The trial judge's finding that the ordinance, which drew a line down Kercheval avenue, is invalid is supported by the record. The city claims that all zoning must begin and end somewhere and that in this case, the lots south of Kercheval avenue are somewhat larger and more valuable than those to the north. The appellee claims that the line is arbitrary, that the ordinance bears no relation to public health, safety or welfare, and that the ordinance is selectively and discriminatorily applied against the hospital.
All zoning begins and ends somewhere and, in that sense, is arbitrary. It is too seldom for practical consideration that a district lies contiguous to a natural border so that its beginning and end will not *352 appear arbitrary. Almost invariably the line is drawn in some seemingly arbitrary position  down the middle of a street or perhaps down the center of a field. It is not for the courts to tell local legislators that they have taken the wrong line unless good reason appears why the line they have chosen is improper. Such reasoning would virtually emasculate all zoning, for in almost every case a use is permitted on one side of the line which is prohibited on the other. Can it ever appear reasonable to the prohibited owner to look but a short distance across an arbitrary line and see the use permitted there which is prohibited to him? But the only alternative is no district demarcation at all, for natural boundaries are not prevalent in our large metropolises. A contrary result can only suggest grey areas or buffer zones in which the permitted uses gradually taper into the prohibited. This suggestion, as should be obvious, would surely be the death knell of all zoning.
The defendant city of Grosse Pointe cites authority to this Court of a well-recognized principle that we do not sit as a superzoning board and that in order to invalidate an ordinance the challenging party must first overcome the presumption of validity with which each such ordinance comes clothed; Brae Burn, Inc., v. City of Bloomfield Hills (1957), 350 Mich 425. Completely digesting the meaning of Brae Burn and its progeny is no small task. It is crucial to note that Brae Burn involved property claimed to be useless because of the application of the ordinance. In many zoning cases, before the Supreme Court as well as this Court, a property owner contended that his parcel or tract should really be zoned commercial rather than residential and assigned as a basis therefor that his property is worth less under the ordinance than it would be under different zoning. Thus with understandable *353 shortness the Supreme Court in Brae Burn expressed its concern with the large number of cases ostensibly seeking a greater dollar return on property which came to the courts under the label of "confiscation." It is in this respect that the courts have refused to decide whether a parcel would be better zoned as this use or that use, or whether the line should run down this street or the next.
But to read Brae Burn as suggesting that the courts will not review zoning ordinances except where there is no debatable question as to its invalidity, is to do injustice to the language of the case itself:
"The function of the courts, with respect to these cases [zoning cases], lies largely in 2 broad areas: (a) has the legislative body the authority to act? (b) have the requirements of administrative due process been observed with respect to adoption, interpretation, and administration of the ordinance in question? The first brings to us the validity and breadth of the delegation of power. The second brings to us the legality of its use, whether the ordinance was properly adopted, whether exercised as to all alike, regardless of local pressures and improper influences, and similar questions. These are the areas in which we may be presumed to have some degree of competence." Brae Burn, supra, at p 437.
Plaintiff in this case does not claim that its property would be better zoned otherwise or that the line should be moved slightly to its advantage. It claims rather that the prohibition of hospitals, churches, schools, et cetera, south of Kercheval avenue bears no relation to the promotion of the public health, safety, morals, or welfare of the community and is therefore invalid. It further contends that because the city allowed a church[9] to be built within the district *354 while denying the hospital's request to expand, the ordinance was being discriminatorily applied to deny plaintiff the equal protection of the law.
We shall not discuss the ramifications of allowing one prohibited use in a district while denying another, for we agree with plaintiff's contention and the trial court's ruling that the "south of Kercheval" prohibition is invalid. While the question has been presented to us on the constitutional plane, the question may also be resolved on the statutory level. To be invalid, a city's enactments need not go so far as to transgress the Constitution  but may simply transgress the statutes from which all local zoning power is derived. Clements v. McCabe (1920), 210 Mich 207.
The State enabling act is CL 1948, § 125.581 et seq. (Stat Ann 1958 Rev § 5.2931 et seq.) which provides in section 1 as follows:
"The legislative body of cities and villages may regulate and restrict the location of trades and industries and the location of buildings designed for specified uses and for such purposes divide any city or village into districts of such number, shape and area as may be deemed best suited to carry out the provisions of this section. For each of such districts regulations may be imposed designating the uses for which buildings or structures shall or shall not be erected or altered, and designating the trades and industries that shall be permitted or excluded or subjected to special regulations. Such regulations shall be made in accordance with a plan designed to lessen congestion on the public streets, to promote public health, safety and general welfare, and shall be made with reasonable consideration, among other things, to the character of the district, its peculiar suitability for particular uses, the conservation of property values and the general trend and character of building and population development."
*355 And, as appropriate commentary on this grant of power:
"The power granted municipalities to enact zoning ordinances is at all times limited by the word `reasonable.' There can be no question that in the interest of the public health, safety, and general welfare, the municipality has authority to adopt a proper zoning ordinance; but in adopting any ordinance it must meet the test of reasonableness." Christine Building Company v. City of Troy (1962), 367 Mich 508, 518, 519.
Thus the test of reasonableness is the criterion of validity or invalidity of any zoning ordinance, Hitchman v. Township of Oakland (1951), 329 Mich 331. And, as stated in Archbishop v. Orchard Lake, supra, at p 392:
"The owner's right to use is, however, subject to reasonable regulation, restriction and control by the State in the legitimate exercise of its police powers. The test of legitimacy is the existence of a real and substantial relationship between the exercise of those powers in a particular manner in a given case and public health, safety, morals or the general welfare."
The obvious problem of validity in a case such as this is that a hospital is directly and critically connected to the promotion of public health while such concepts as property values or traffic are but indirectly connected. In deciding the reasonableness of the ordinance or its relation to the objectives of the police power, the question is simply whether the prohibitions south of Kercheval have a sufficient relation to public health, safety, morals and welfare of the entire community to bar hospitals and other public or semipublic institutions.
A case cited to us by appellee, from which we quote with approval, is American University v. Prentiss *356 (DC 1953), 113 F Supp 389.[10] American University, a large institution in Washington, D.C., intended to erect a hospital on its campus in conjunction with the university's school of nursing. The campus was zoned residence A, in which hospitals were a permitted use. A number of residents, owners of expensive homes adjacent to the proposed hospital site, objected to the new structure on the basis that it would create traffic congestion, generate noise and impair their property values. The zoning commission, in response to such protests, rezoned the entire 70 acre campus to "Residence A, restricted," in which hospitals were prohibited.
The court discussed many factors of modern hospitals which it considered as bearing upon its decision, to-wit: that the plans called for modern, light-colored structures, to be landscaped and partially obscured from view; and that modern hospitals endeavor to establish "quiet zones" for the welfare of its patients. Moreover the court found that any increases in traffic could be easily absorbed by the existing thoroughfares and that ample parking facilities would obviate the danger of congestion on the neighboring streets.
The court found that the testimony regarding the projected decline in surrounding property values was "based on sheer speculation and pure conjecture." On the other hand, the construction of a hospital is a proper and natural use of the university campus and the pleasantness and quiet of the surroundings would likewise advance the welfare of the patients.
Based on these factors, the court found the restrictive ordinance bore no reasonable relation to *357 the public safety, health, morals, or the general welfare:
"`The governmental power to interfere by zoning regulations with the general rights of the land owner by restricting the character of his use, is not unlimited, and, other questions aside, such restriction cannot be imposed if it does not bear a substantial relation to the public health, safety, morals, or general welfare.' Nectow v. City of Cambridge, 277 US 183, 188 (48 S Ct 447, 448, 72 L ed 842, 844)." American University v. Prentiss, supra, at p 394.
Likewise in the record before us we can find no such relationship. The city offers that south of Kercheval the lots are somewhat larger and more valuable, but no evidence of such differences is apparent from the record.[11] This objective of the ordinance is somewhat tenuous compared to the benefits to the community of hospitals, schools, churches, and the like. The city suggests that one may operate a hospital north of Kercheval, but this is unreasonable in face of evidence that there is no land readily available north of Kercheval for such purpose. It is altogether difficult to find any direct and substantial relationship between the public weal and the "south of Kercheval" prohibition.
On the other side of the coin, the plaintiff has shown that it handles upwards of 10,000 emergency cases in a year and that its patients include residents from the city of Grosse Pointe as well as neighboring communities. Plaintiff has demonstrated that the hospital is overcrowded and usually maintains an in-patient waiting list. Other testimony disclosed that the hospital is in danger of losing its internship *358 and residency accreditation unless it expands. Additionally, there was testimony of the need for hospital beds in this area based on the published recommendations of the Greater Detroit Hospital Council.
Without further summarizing the testimony produced at trial, it is sufficient to say that the evidence produced by the plaintiff, if believed by the trial judge, amply supports the trial court's finding that the "south of Kercheval" zoning regulation (section 3.12) was unreasonable and bore no substantial relation to public health, safety, morals, or the general welfare.
Our decision should not be construed as prohibiting local government's reasonable regulation of hospitals and their location within the municipality's diverse districts, but in this case such regulation was not made to further development of a particular type of district; rather it cut across different districts. The infirmity in this case lies in the lack of relationship between the blanket "south of Kercheval" prohibition and any conditions in that area which would indicate a substantial relation to the public well-being. For the lack of such relationship, this superimposed ban is fatally defective as an improper exercise of statutory authority to zone. The relationship, if in fact one exists, must appear from the condition of the community as appears at the time, not from some future hypothetical set of facts. Christine Building Company v. City of Troy, supra.
Plaintiff has also challenged, as being arbitrary and unreasonable, the provisions of section 3.11(c)(2) of the Grosse Pointe ordinances which require hospitals to have 1 off-street parking space per patient bed and 1 space for each 5 staff positions. Section 3.11 includes diverse types of uses including hospitals *359 and the requirements under each use are imposed uniformly throughout the city.
Plaintiff's sole argument against the validity of section 3.11(c) (2) is, as stated in its complaint: "Plaintiff is informed and believes that such off-street parking requirements for hospitals are in excess of similar requirements of most municipalities in Wayne county, Michigan."
It should be eminently clear that requirements for off-street parking bear a substantial relation to lessening congestion and traffic in the public streets as well as protecting residential owners throughout the city from the possibility of many cars parking at their curbs. The restrictions, unless their requirements are unreasonable, do bear a substantial relation to the public safety, health, morals, and welfare. Uday v. City of Dearborn (1959), 356 Mich 542. On its face, this requirement is valid. Plaintiff has not met its burden of coming forward with evidence that the requirements of section 3.11(c) (2) are unreasonable. Merely to say that it is believed to be higher than other Wayne county municipalities is not convincing and the argument addressed to this point merely asks this Court to invade the legislative function. Brae Burn, Inc., v. City of Bloomfield Hills, supra.
The trial judge's finding that this section constituted a deprivation of property without due process of law is not supported by the record.
From the point of recognizing the validity of section 3.11(c) (2), plaintiff complains of the denial of its petition to rezone a certain parcel owned by it to allow for off-street parking. This parcel is 83 feet by 785 feet running north-south just adjacent to the hospital property proper. Residences line the length of the parcel on both sides with the backyards bordering on the parcel and the houses facing the *360 adjacent streets. The only access to the property is from either end of the long rectangle.
When the hospital acquired this property in May, 1956, it was zoned residence B (footnote 1, supra) which allowed "accessory uses customarily incident to any of the above permitted uses." Hospitals were one of the above permitted uses, subject, however, to the "south of Kercheval" prohibition. Based on our finding of invalidity of the Kercheval line, the terms and provisions of the B district remain in force in those districts so designated. In other words, Bon Secours, by our above holding, remains a permitted rather than a nonconforming use located in B district.
The many petitions to rezone and the numerous problems dealt with by the trial court have led to apparent confusion on this appeal with respect to this separate strip of land. We need not discuss the question of validity of the parking ordinance in conjunction with the plaintiff's claim of "confiscation" or the claim that the narrow strip is "dead land" by prohibiting the use of the parcel as parking. The legitimate and legal use of this strip turns on the uses permitted under a B district classification. If hospitals were prohibited, there exists no showing of justification to use the parcel as parking  that is, unless no other legal use could be made. As it is, however, hospitals are a permitted B use and this parcel goes right along as an "accessory use customarily incident" thereto.
The trial judge found section 3.15, imposing height restrictions throughout the city, to be unconstitutional and to bear no substantial relation to the proper objectives of the police power. This finding is erroneous.
The concept of building height restrictions is virtually universally accepted as bearing a substantial *361 relation to public health, safety, morals and welfare. See Village of Euclid v. Ambler Realty Company (1926), 272 US 365 (47 S Ct 114, 71 L ed 303).[12] Again, the test of the validity of such restrictions is their reasonableness  that is, their relation to the promotion of the public good. On its face the ordinance in question here displays no infirmities and is in fact substantially identical to the ordinance discussed in Taber v. City of Benton Harbor (1937), 280 Mich 522, wherein the city itself was held bound by the height restriction.
We are unable to find any evidence on this record to justify the conclusion of unconstitutionality of the height restriction ordinance reached by the trial court. When reasonably related to the public good even so valuable an institution as a hospital must be subject to reasonable local regulations. DeGaynor v. Dickinson County Memorial Hospital Board of Trustees (1961), 363 Mich 428.
In summation we uphold the trial court's determination that the "use" ordinance prohibiting hospitals south of Kercheval is invalid. We further hold that the hospital may use its 83-foot strip of land for parking purposes as an accessory use normally incident to the operation of a hospital. Finally, we hold the ordinance amending the height restriction is valid. We do not pass upon the issue of whether the hospital should or should not come within the purview of that portion of Ordinance No 96, § 3.15, authorizing the council to approve the erection of a building of a height greater than 3 full stories or 36 feet above grade, since this issue is not before this Court on appeal.
No costs, neither party having prevailed in full.
McGREGOR and THORBURN, JJ., concurred.

[2]  Ordinance No 96, § 3.12, provided:

"Regardless of anything otherwise contained in the zoning ordinance of the city of Grosse Pointe, and in addition to the other restrictions contained therein applicable to the building and lands in the area hereinafter described, no land in the city of Grosse Pointe south of Kercheval avenue shall be used for a public or private school; a church or other place of worship; a parish house; a community building or property; a hospital; a sanitarium; a convalescent home; a home for the aged, feeble, children, or the like; an educational, religious or philanthropic institution; a penal or a correctional institution; or for any use of a nature similar to any one or any combination of the foregoing; or for business of any kind excepting buildings and lands in local business districts. Nor shall any building now erected upon any of such land, nor shall any building hereinafter erected upon any of such land, be so used. Existing nonconforming uses at the effective date of this amendment shall be subject to section 3.1 of the zoning ordinance of the city of Grosse Pointe."
[3]  Ordinance No 96, § 3.15 (as added by Ordinance No 112) provided:

"Anything herein contained to the contrary notwithstanding, no building shall be erected in the city of Grosse Pointe to a height greater than 3 full stories or 36 feet above grade, whichever is lower, unless the city council grants prior specific approval.

Without such division of the community into zones, special regulations for different sections of the community in accordance with a plan of development would not be of legal effect. Accordingly, zoning restrictions may vary according to the use classifications established for each type of zone, but regulations within one zone or within similar zones must be uniform. Different regulations in different zones will therefore result in different land uses from one zone to the next, but to be valid they must avoid discrimination in the application of those restrictions or regulations with respect to property similarly situated either within a given zone or within zones indistinguishable from each other as to physical factors present."
