OPINION OF THE COURT
Notwithstanding that a previously granted conservation easement proscribes erection of residences on part of the land included in a cluster zoning application, the land thus burdened may be counted in determining the number of residential units that may be erected on the unburdened acreage. A conservation easement is not an “applicable requirement” within the meaning of Town Law § 281 (b), and nothing in the Town Law or the Environmental Conservation Law forecloses the owner of the fee under land thus burdened from using it as open area required under the cluster zoning ordinance. The Appellate Division having annulled the Planning Board’s approval of intervenor’s

Lake Minnewaska Mountain Houses, Inc. (Mountain Houses), owns approximately 450 acres of land located on Lake Minnewaska in the Town of Rochester, Ulster County. In 1977, Mountain Houses sold to the Palisades Interstate Park Commission (PIPC) a conservation easement on 240 acres of the land contiguous to the 10,000 acre Minnewaska State Park owned by PIPC. The easement permits the erection of one single family residence, a potable water storage pond and the maintenance of the existing golf course and accessory areas, but otherwise proscribes development of the 240 acres. By agreement dated February 26,1980, Mountain Houses sold the entire 450 acres to the Marriott Corporation, 1 subject, however, as a condition precedent to closing, to Marriott’s obtaining approval of subdivision of the property to permit construction of a hotel and condominium units.
In April 1982, Marriott applied to the Town Planning Board for approval of a plat of the 450 acres calling for construction of a hotel and 300 residential condominium units, the condominium units to be clustered on part of the 210 acres not covered by the conservation easement. The district in which the 450 acres is located requires a plot of one or more acres per residential uni t. After notice to interested parties and a public hearing on the application, the Planning Board approved the requested 300 units. PIPC, though given notice, interposed no objection.
Petitioners, eight individual owners of nearby properties and two not-for-profit conservation organizations, then commenced this article 78 proceeding against the Planning Board. Special Term granted Marriott’s application to intervene and on the merits dismissed the petition. The Appellate Division reversed, concluding that the 240 acres subject to the conservation easement could not be counted in determining the number of uni bs permissible under the town’s cluster zoning resolution, because the conservation easement constituted an “applicable requirement” within the meaning of Town Law § 281 (b), the enablin g act pursuant to which the cluster zoning provisions of the zonin g ordinance were adopted. Both the Planning Board and Marrio tt appeal as of right.
“The town board is hereby empowered by resolution to authorize the planning board, simultaneously with the approval of a plat or plats pursuant to this article, to modify applicable provisions of the zoning ordinance, subject to the conditions hereinafter set forth and such other reasonable conditions as the town board may in its discretion add thereto. Such authorization shall specify the lands outside the limits of any incorporated village to which this procedure may be applicable. The purposes of such authorization shall be to enable and encourage flexibility of design and development of land in such a manner as to promote the most appropriate use of land, to facilitate the adequate and economical provision of streets and utilities, and to preserve the natural and scenic qualities of open lands. The conditions hereinabove referred to are as follows:
* * *
“(b) The application of this procedure shall result in a permitted number of building plots or dwelling units which shall in no case exceed the number which could be permitted, in the planning board’s judgment, if the land were subdivided into lots conforming to the minimum lot size and density requirements of the zoning ordinance applicable to the district or districts in which such land is situated and conforming to all other applicable requirements.
* * *
“(d) In the event that the application of this procedure results in a plat showing lands available for park, recreation, open space, or other municipal purposes directly related to the plat, then the planning board as a condition of plat approval may establish such conditions on the ownership, use, and maintenance of such lands as it deems necessary to assure the preservation of such lands for their intended purposes. The town board may require that such conditions shall be approved by the town board before the plat may be approved for filing.”
The Town of Rochester, pursuant to that authorization, has incorporated in its zoning ordinance provisions for residential cluster development permitting its Planning Board to vary the residential density within a tract provided that the proposed development produces a total acreage density as specified for the district in which located and guarantees permanent retention and maintenance of “open areas.”
II
The use that may be made of land under a zoning ordinance and the use of the same land under an easement or restrictive covenant are, as a general rule, separate and distinct matters, the ordinance being a legislative enactment and the easement or covenant a matter of private agreement
(see, Ginsberg v Yeshiva of Far Rockaway,
Petitioners seek to distinguish those rules as related only to covenants and easements appurtenant to an interest in real property, whereas a conservation easement, as defined in article 49 of the Environmental Conservation Law, may be held only by a public body or not-for-profit conservation organization (ECL 49-0305 [3] [a]) and is enforceable notwithstanding that it is of a character wholly distinct from the easements traditionally recognized at common law and notwithstanding defenses that would defeat a common-law easement (ECL 49-0305 [5]). The short answer to the argument is that ECL article 49 was not enacted until 1983 and that PIPC does own the adjacent Minnewaska State Park. Thus the easement granted PIPC in 1977 was a common-law easement appurtenant, which, whatever its burden upon intervenor’s use of the 240 acres it covered, cannot be construed to be an “applicable requirement” within the meaning of Town Law § 281 (b), unless the usual rule that words
More importantly, the present version of Town Law § 281 was enacted by chapter 963 of the Laws of 1963, 20 years before enactment of the Environmental Conservation Law provisions relating to conservation easements (L 1983, ch 1020). Petitioners point to nothing in the legislative history of either statute to suggest a legislative intent to include within the concept of the “other applicable requirements” referred to in Town Law § 281 (b), such an easement rather than other zoning and planning requirements imposed by the Town Law. This, therefore, is not a case such as
Baddour v City of Long Beach
(
Nor are petitioners aided, as they suggest, by the provision of the Environmental Conservation Law authorizing enforcement of its provisions by parties other than the grantor or holder of the easement. To the contrary, that provision refutes their position for if Town Law § 281 (b) is construed as allowing nearby landowners to block cluster subdivision as contrary to the conservation easement, the class of persons having standing to enforce a conservation easement will have been expanded significantly beyond the limits deliberately set by the Legislature in the ECL. 4
The argument that, because the 240 acres subject to the easement cannot be built upon while the easement continues in force, the burdened land may not be counted in determining cluster zoning density is of no greater aid to petitioners. “[I]t is undisputed that the PIPC does not own the land burdened by the easement. It merely has an easement, which is
‘a
right, distinct from ownership, to use in some way the land of another’ ”
(Matter of Sierra Club v Palisades Interstate Park Commn.,
As the conditional vendee of the fee of the 450-acre tract, Marriott is entitled to have the entire 450 acres considered in determining the permissible number of dwelling units. One of the major purposes of cluster zoning being the preservation of the natural and scenic qualities of open land, it is fundamentally inconsistent with the statutory purpose to hold that because that part of the land that will be thus preserved under a cluster zoning proposal is also subject to an easement that preserves it as open land, it may not be counted in determining density. The more so is this true in light of the case law, discussed above, holding zoning ordinances and restrictive covenants to be separate and distinct matters. 5
For the foregoing reasons the order of the Appellate Division should be reversed, with costs, and the judgment of Special Term, Ulster County, should be reinstated.
Chief Judge Wachtler and Judges Jasen, Simons, Kaye and Alexander concur.
Order reversed, with costs, and judgment of Supreme Court, Ulster County, reinstated.
Notes
. The agreement also covered additional acreage not involved in this proceeding.
. Village Law § 7-738 contains essentially identical provisions and General City Law § 37 includes comparable, though not identical, provisions.
. The reference in Town Law § 281 (b) to “requirements of the zoning ordinance” implies that the “other applicable requirements” in its concluding phrase be governmental, if not legislative, in origin. PIPC, formed under interstate compact (PRHPL 9.01), is a governmental agency, but it has purchased an easement, not imposed a governmental requirement.

. Whether such a proscription (as distinct from a provision requiring refund of part of the acquisition price) can be made part of a conservation easement which is otherwise not more burdensome than the use permitted for a cluster zoning open area is a question beyond the scope of this case, on which we express no opinion.
. The record contains a proposed Restated and Amended Conservation Easement Agreement which specifically reserves that right to Marriott, but we are not advised whether in fact it has since been executed
