ITEM 1.       SECURITY AND ISSUER

         This statement on Schedule 13D (the "Statement") relates to the common
shares of beneficial interest, par value $.001 per share (the "Common Shares")
of Acadia Realty Trust, a Maryland real estate investment trust (the "Trust"),
whose principal executive offices are located at 20 Soundview Marketplace Shore
Road, Port Washington, NY 11050.

ITEM 2.       IDENTITY AND BACKGROUND

         (a)      This Statement is being filed by Yale University, a
Connecticut corporation (the "Reporting Person").

         (b)      The business address of the Reporting Person is c/o
Yale University Investments Office, 230 Prospect Street, New Haven,
CT 06511-2107.

         (c) The Reporting Person is a large research university with a wide
array of programs, departments, schools, centers, museums, and affiliated
organizations. The Reporting Person invests money for its endowment.

         (d) The Reporting Person has not, during the last five years, been
convicted in a criminal proceeding (excluding traffic violations or similar
misdemeanors).

         (e) The Reporting Person has not, during the last five years, been a
party to a civil proceeding of a judicial or administrative body of competent
jurisdiction and as a result of such proceeding was or is subject to a judgment
decree or final order enjoining future violations of, or prohibiting or
mandating activities subject to, federal or state securities laws or a finding
of any violation with respect to such laws.

         (f) The name, business address and present principal occupation or
employment of each of the fellows and executive officers of the Reporting Person
are set forth in Annex A to this Statement and are incorporated herein by
reference. Unless otherwise indicated in Annex A, each of the fellows and
executive officers of the Reporting Person is a citizen of the United States. To
the Reporting Person's best knowledge and belief, none of the Reporting Person's
fellows or executive officers has been convicted in a criminal proceeding or was
or is subject to a civil judgment of the type described in clauses (d) or (e)
above.

ITEM 3.       SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION

         The source of funds for the purchases of 8,421,759 Common Shares
reported by the Reporting Person was working capital of the Reporting Person.
The Reporting Person received such funds as gifts from donors to support its
programs and net investment gains thereon. The source of funds for the purchases
of 403,994 Common Shares reported by the Reporting Person was working capital of
Yale University


                                  Page 3 of 11


Retirement Plan for Staff Employees ("YURPSE"). YURPSE received such funds as
contributions from Yale and net investment gains thereon.

ITEM 4.       PURPOSE OF TRANSACTION

         The Common Shares were acquired by the Reporting Person for the purpose
of investment.

         On September 17, 2002, an employee of the Reporting Person was elected
to the Board of Trustees of the Trust. This Schedule 13D filing, in lieu of the
Reporting Person's normal filing on Schedule 13G, is occasioned solely by the
joining of the Trust's Board of Trustees by the Reporting Person's employee.
Because of his election to the Trust's Board of Trustees, it is possible that
the Reporting Person's investment in the Trust could be viewed as having the
purpose or affect of changing or influencing the control of the issuer. In order
to avoid any question as to whether the Reporting Person's beneficial ownership
is being reported on the proper form and in order to provide greater investment
flexibility, the Reporting Person has decided to file its beneficial ownership
reports on the more detailed Schedule 13D rather than on the short-form Schedule
13G and thereby to provide more expansive disclosure than may be necessary. This
Schedule 13D shall not be deemed an admission that the Reporting Person is
required to file its beneficial ownership reports on Schedule 13D rather than on
Schedule 13G.

         The Reporting Person may, depending on market conditions, the trading
prices for the Common Shares, alternative investment opportunities, the
availability of funds, and the outlook for the sector and for the Trust, acquire
additional Common Shares, or may sell all or part of its holdings of Common
Shares, in the open market or in privately negotiated transactions. Except as
set forth above, the Reporting Person has no plans or proposals with respect to
any of the matters set forth in paragraphs (a) through (j) of Item 4 of Schedule
13D. The Reporting Person may, at any time and from time to time, review or
reconsider its position with respect to the Trust, and formulate plans or
proposals with respect to any such matters.

ITEM 5.       INTEREST IN SECURITIES OF THE ISSUER

         (a) The Reporting Person beneficially owns, within the meaning of Rule
13d-3 under the Exchange Act, 8,825,753 Common Shares. The Common Shares owned
by the Reporting Person constitute approximately 35.6% of the Common Shares
issued and outstanding (computed on the basis of 24,800,328 Common Shares issued
and outstanding, as reported in the Trust's Form 10-Q for the quarterly period
ended June 30, 2002 filed with the Securities and Exchange Commission on August
13, 2002).

         (b) The Reporting Person has sole power to dispose of 8,421,759 Common
Shares and shared power to direct the disposition of 403,994 Common Shares held
of record by YURPSE. YURPSE has shared power to direct the disposition of
403,994 Common Shares.

                                  Page 4 of 11


         The Reporting Person has sole power to vote 7,440,098 Common Shares and
shared power to direct the vote of 403,994 Common Shares held of record by
YURPSE. YURPSE has shared power to direct the vote of 403,994 Common Shares.

         The Reporting Person disclaims beneficial ownership of the Common
Shares held by YURPSE.

         The Trust has sole power to vote 981,661 Common Shares beneficially
owned by the Reporting Person (see the first paragraph of Item 6 below, which is
incorporated herein by reference).

         (c)-(e)  Not applicable

ITEM 6.       CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS
              WITH RESPECT TO SECURITIES OF THE ISSUER

         Pursuant to an agreement between the Reporting Person and the Trust
dated as of February 27, 2002 (the "Voting Trust Agreement"), the number of
Common Shares held by the Reporting Person in excess of 30% of all Common Shares
outstanding at any given time is required to be placed in a voting trust as to
which the Trust acts as voting trustee and has the exclusive right to vote such
Common Shares. As of this date, 981,661 Common Shares beneficially owned by the
Reporting Person are subject to the Voting Trust Agreement. The Voting Trust
Agreement will terminate at the time the Reporting Person's ownership of the
Common Shares is 5% or less of all Common Shares outstanding or when terminated
at the discretion of the Trust. The Trust is required to vote the Common Shares
that are subject to the Voting Trust Agreement in exact proportion to the actual
vote of all Common Shares voting.

         Other than the Voting Trust Agreement, there are no contracts,
understandings or relationships (legal or otherwise) among the persons named in
Item 2 hereof and between such persons or any person with respect to any
securities of the Trust including but not limited to transfer or voting of any
of the Common Shares, finder's fees, joint ventures, loan or option
arrangements, puts or calls, guarantees or profits, division of profits or loss,
or the giving or withholding of proxies.

ITEM 7.       MATERIAL TO BE FILED AS EXHIBITS

         1.       Voting Trust Agreement between the Reporting Person and the
                  Trust dated as of February 27, 2002.

that the information set forth in this statement is true, complete and correct.
