mission. Any plat submitted 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 acted upon by the Commission without af-
fording a hearing thereon, notice of the time and place of which
shall be sent by mail to said address not less than five (5) days be-
fore the date fixed therefor. In his application, however, the ap-
plicant 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 regulations may include pro-
visions for notice to owners of properties that would be substantially
affected by approval of any sub-division plat and for public hearings
on such applications.

73.    Conveyance of Property Before Plat is Approved.

If the owner or agent of the owner of any land located within a
sub-division, transfers or sells any land by reference to or exhibition
of or by other use of a plat of a sub-division, before such plat has
been approved by the Commission and recorded or filed in the office
of the Clerk of the Circuit Court of the county in which the property
is located, he shall forfeit and pay to the District Council a penalty
of one hundred dollars ($100) for each lot or parcel so transferred
or sold. The description of the lot or parcel by metes and bounds
in the instrument of transfer or other document used in the process
of selling or transferring shall not exempt the transaction from such
penalties or from the remedies herein provided. The District Coun-
cil may enjoin such transfer or sale or agreement by action for in-
junction brought in any court of equity jurisdiction or may recover
the penalty by a civil action in any court of competent jurisdiction.

74.    Recordation of Plats; Approval of Commission Required.

No clerk of the Circuit Court of Montgomery or Prince George's
counties shall receive for filing or recording or record any plat of
a sub-division of land within the Regional District unless the plat
has endorsed thereon in writing the approval of the Commission. In
the event any such plat not so approved is recorded after May 24,
1939, the plat is invalid, and the Commission has the right to in-
stitute proceedings against the Clerk to compel the plat to be stricken
from the land records of the county; and for such purpose any court
of competent jurisdiction has jurisdiction to issue appropriate orders.

75.    Zoning Regulations Authorized; District Councils.

The County Council of Montgomery County and the Board of
County Commissioners of Prince George's County are respectively
empowered, in accordance with the conditions and procedures speci-
fied in Sections 76, 77, 78, 80, 81, 83, 84, 86 and 98 of this sub-title,
to regulate in the portion of the Regional District lying within its
county, (1) the location, height, bulk, and size of buildings and other
structures, building lines, minimum frontages, depths and areas
of lots, and percentages of lots which may be occupied; (2) the
sizes of yards, courts, and other open spaces; (3) the erection of
temporary stands and structures; (4) the density and distribution
of population; (5) the uses of buildings and structures for trade,
industry, residence, recreation, agriculture, public activities, or
other purposes; and (6) the uses of land for trade, industry, res-
