[(2) Any Plans Now Adopted Shall Remain Effective. In
Montgomery County, with regard to local master plans in prepara-
tion, but not adopted on or before the effective date of this Act, the
Commission shall submit to the Council a statement of the concepts
guidelines, and goals which it is following in the preparation of
each such plan. Such statement shall be approved or disapproved in
accordance with the procedure set forth in Section (f).]

1(72) (70-83) (59-77) Approval or disapproval of subdivision plats
and Prince George's County preliminary Subdivision Plans.

The commission shall approve or disapprove a subdivision plat
within thirty (30) days after the submission thereof; otherwise, the
plat shall be deemed to have been approved, and a certificate to that
effect shall be issued by the commission upon demand. In Prince
George's County, each office to which a preliminary subdivision plan
is referred will return one copy of the plan to the Board
within thirty (30) days with its comments noted thereon; if
such reply is not made within thirty (30) days by any office to whom
referred, the plan shall be deemed to be approved by it. In Prince
George's County, the commission shall approve or disapprove a pre-
liminary subdivision plan within seventy (70) days after the sub-
mission thereof; otherwise, the preliminary subdivision plan shall be
deemed to have been approved, and a certificate to that effect shall
be issued by the commission upon demand. The applicant for the
commission's approval may waive either or both of these require-
ments and consent to the extension of such periods; provided, how-
ever, that in Prince George's County no such waiver may be for a
period greater than the original period allowed for approval of such
plat or preliminary plan. The ground of disapproval of any plat
shall be stated upon the records of the commission. Any plat sub-
mitted to the commission shall contain the name and address of a
person to whom notice of hearing may be sent; and no plat shall be
sent by mail to said address not less than five (5) days before the
date fixed therefor. In his application, however, the applicant may
waive such hearing and notice, and the approval of any plat exactly
as submitted by the applicant shall be deemed a waiver of such
hearing and notice. [Such] The subdivision regulations may include
provisions for notice to owners of properties that would be sub-
stantially affected by approval of any subdivision plat and for public
hearings on such applications [.] and may include provisions for an
appeal to the District Council from a decision approving or dis-
approving a subdivision plat.]
