final plat or within such further time as agreed to by the applying
party. Unless during such one-year period or extension thereof, the
County Commissioners or Board of Education as the case may be,
shall have entered into or approved a contract to purchase, or insti-
tuted condemnation proceedings according to law, for said school
site, park or playground, the subdivider shall not be bound by the
proposals for such areas shown on the Master Plan. This provision
shall not apply to the streets and roads, drainage rights-of-way or
flood areas in fee, required for final approval of any plat and deemed
essential to the public welfare.

(d) Before final approval of subdivisions the County Commis-
sioners may require, in accordance with the subdivision regulations,
the execution of a Public Works Agreement for any or all of the
following improvements it may deem to be necessary or appropriate:
street grading, pavement, gutters, curbs, sidewalks, street lighting,
shade trees, surveyor's monument's, water mains, culverts, storm
sewers, sanitary sewers or other means of sewage disposal, drainage
structures, and such other subdivision improvements as the County
Commissioners may find necessary in the public interest. The Public
Works Agreement shall set forth the amount of the funds required
to be paid by the County and the developer or owner of the sub-
division.

463.    (a) Final plats of subdivisions shall conform to the stand-
ards prescribed by Article 17, Sections 71 and 72, of the Annotated
Code of Maryland (1951 Edition, as amended). A final plat shall be
deemed to have been submitted when an application for approval has
been delivered to the office of the Planning Board in conformance
with the printed requirements governing the submission of sub-
division plats.

(b)   The Planning Board may approve or after hearing disapprove
a plat. If the Planning Board disapproves any plat, the findings and
reasons for such disapproval shall be stated upon the records of the
Planning Board, and the applicant shall be given a copy.

(c)   Where approval of a plat, map or plan of land is required by
any officer or body of the County, including the Board of Health,
Department of Public Works, Board of Education and Board of
Recreation, under the provisions of any other law or ordinance, such
approval shall be certified on the plat before the final plat shall be
approved as a prerequisite to its acceptance for filing by the Clerk
of the Circuit Court.

(d)   The Planning Board shall take action under this section within
45 days after submission of the final plat for approval, or within such
further time as the applying party may agree to. Otherwise such plat
shall be deemed to have been given favorable approval. Such approval
by default, however, shall not be valid unless all necessary prerequi-
sites for approval of a final plat have been fulfilled by the applicant.

464.    The final approval by the Planning Board of a plat shall
expire 90 days from the date of such approval, unless within the
period such plat shall have been duly filed by the owner or his agent
with the Clerk of the Circuit Court for recording. The Planning
Board for good cause shown may extend the time for plat filing for
a period not to exceed 90 days.
