                                POWER OF ATTORNEY

        KNOW ALL PERSONS BY THESE PRESENTS, that I, the undersigned officer of
Seritage Growth Properties, a Maryland real estate investment trust (the
"Company"), hereby constitute and appoint Benjamin Schall and Matthew E.
Fernand, and each of them, my true and lawful attorneys-in-fact and agents, with
full power to act, together or each without the other, for me and in my name,
place and stead, in any and all capacities, to execute and file for and on
behalf of the undersigned (i) any reports on Forms 3, 4 and 5 (including any
amendments thereto and any successors to such Forms) with respect to ownership
of securities of the Company, that the undersigned may be required to file with
the U.S. Securities and Exchange Commission in accordance with Section 16(a) of
the Securities Exchange Act of 1934 and the rules thereunder and (ii) any other
documents necessary or appropriate to obtain codes and passwords enabling the
undersigned to file such reports electronically.

        The undersigned acknowledges that the foregoing attorney-in-fact, in
serving in such capacity at the request of the undersigned, is not assuming, nor
is the Company assuming, any of the undersigned's responsibilities to comply
with Section 16 of the Securities Exchange Act of 1934. The Company will use all
reasonable efforts to apprise the undersigned of applicable filing requirements
for Section 16 purposes.

        This Power of Attorney shall remain in full force and effect until the
undersigned is no longer required to file Forms 3, 4 and 5 with respect to the
undersigned's holdings and transactions in securities issued by the Company,
unless earlier revoked by the undersigned in a signed writing delivered to the
foregoing attorney-in-fact. This Power of Attorney revokes and replaces any
prior Power of Attorney executed by the undersigned with respect to the
ownership of securities of the Company.

        IN WITNESS WHEREOF, the undersigned has caused this Power of Attorney to
be executed as of this 29th day of June, 2015.
