mains, piping, or other facilities shall be installed as a
condition precedent to the approval of the plat. The
regulations or practice of the Planning Commission may
provide for a tentative approval of the plat previous to
such installation; but any such tentative approval shall be
revocable and shall not be entered on the plat. In lieu of
the completion of such improvements and utilities prior to
the final approval of the plat, the Planning Commission
may accept a certified check or a bond with corporate
surety to secure to the County the actual construction and
installation of such improvements or utilities at a time and
according to specifications fixed by or in accordance with
regulations of the Planning Commission. The County is
hereby granted the power to enforce such bond by all
appropriate legal and equitable remedies.

(c) Before any regulations shall be submitted to the
Board of County Commissioners of Howard County for
adoption, a public hearing shall be held thereon and all
such regulations, or, if in the opinion of the Planning
Commission it is best, a brief synopsis of such regulations,
sufficient to inform a person of ordinary intelligence of
the nature and contents of such regulations, together with
the time and place of such public hearing, shall be pub-
lished once or more, if the Planning Commission deems
best, in a weekly newspaper published and in general circu-
lation in Howard County. When such regulations are
adopted by said Board of County Commissioners, a copy
thereof shall be certified by said Commission to the Clerk
of the Circuit Court for Howard County, for record.

approve a plat within sixty (60) days after the submission
thereof to it; otherwise such plat shall be deemed to have
been approved, and a certificate to that effect shall be
issued by the Planning [Commissioner] Commission on
demand. Provided, however, that the applicant for the
Planning [Commissioner's] Commission's approval may
waive this requirement and consent for an extension of
such period. The ground of disapproval of any plat shall
be stated upon the records of the Planning Commission.
[Every plat approved by the Planning Commission shall
by virtue of such approval, be deemed to be an amendment
of or an addition to or a detail of the county plan and a
part thereof. ] Approval of a plat shall not be deemed to
constitute or effect an acceptance by the public of any
street or other open space shown upon the plat. The Plan-
ning Commission may, from time to time, recommend to
said County Commissioners amendments to the Zoning
