benefits to the health, comfort, safety and welfare of the pres-
ent and future population of the District.

Such regulations may include provisions as to the extent
and manner in which roads shall be graded and improved,
curbs, gutters and sidewalks shall be built, water, sewer and
other utility mains, piping, connections and other facilities
shall be installed and trees shall be planted as a condition
precedent to the approval of a plat. The regulations or prac-
tice of the Commission may provide for the tentative approval
of a plat previous to such improvements and installations;
but any such tentative approval shall not be entered on the
plat or entitle the plat to filing or record. In lieu of the
completion of such improvements prior to the approval of the
final plat, the Commission may accept a bond with surety to
secure to the Commission the actual construction and installa-
tion of such improvements and installations at a time and
according to specifications fixed by or in accordance with the
regulations of the Commission. The Commission is hereby
granted the power to enforce such bond by all appropriate
legal and equitable remedies.

Before adoption of its subdivision regulations or any sub-
stantial amendment thereof, a public hearing thereon shall be
held by the Commission, thirty (30) days notice of the time
and place of which shall be given by one publication in two
newspapers of general circulation in the District.

SEC. 9. And be it further enacted, That the Commission
shall approve or disapprove a subdivision plat within thirty
days after the submission thereof; otherwise such plat shall
be deemed to have been approved and a certificate to that
effect shall be issued by the Commission upon demand; pro-
vided, however, that the applicant for the Commission's ap-
proval may waive this requirement and consent to the exten-
sion of such period. The ground of disapproval of any plat
shall be stated upon the records of the Commission. The ap-
plicant shall furnish to the Commission 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 afford-
ing a hearing thereon, notice of the time and place of which
shall be sent by mail to said address not less than five days
before the date fixed therefor; provided, however, that in his
application 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.

SEC. 10. And be it further enacted, That the approval of a
plat by the Commission shall not in and of itself be deemed
to constitute or effect an acceptance by the public of the dedi-
cation of any road or ground shown on the plat.
