by resolution after public hearing. Copies of the Subdivision Regu-
lations shall be made available to the public, and a reasonable charge
therefor may be made.

459.    Any such Subdivision Regulations may exempt from the
requirements of governmental approval, subdivisions wherein the
number of new lots is less than a designated number, or plats that
do not involve new streets, or such other plats of subdivisions as such
ordinance shall designate. In all cases involving such exempted sub-
divisions, the Planning Board Chairman, or its Director, shall certify
the exemption on the plat, deed or instrument to be filed with the
Clerk of the Circuit Court for recording.

460.    The County Commissioners of Baltimore County may ap-
point a Joint Committee for the processing and approval of sub-
division plats. The Joint Committee shall consist of representatives
of the office of Planning and the Department of Public Works and
shall be known as the Joint Subdivision Planning Committee. The
approvals of the Joint Subdivision Planning Committee shall be in
addition to those required by the Planning Board and the Depart-
ment of Public Works.

461.    The Joint Subdivision Planning Committee shall establish
such rules and regulations as they may consider necessary for proper
public notice regarding proposed subdivisions and hearing thereon.

462.    (a) In acting upon subdivisions, the Planning Board shall
require, among other conditions in the public interest, that the tract
shall be adequately drained, and the streets shall be of sufficient
width and suitable grade and suitably located to accommodate the
prospective traffic, to provide access for fire-fighting equipment to
buildings and to be coordinated so as to comprise a convenient sys-
tem, conforming to the official map, or if there is no official map,
relating properly to the existing street system. Where the Planning
Board after hearing has adopted portions of the Master Plan with
proposals regarding the street system within the proposed sub-
division, the Board may require that the streets shown conform in
design and in width to the proposals shown on the Master Plan. No
street shall be less than 50 feet within right of way lines and shall
be of such width as may be required in the subdivision regulations
or as shown on the Master Plan or Official Map of the County.

(b)   The Planning Agency shall further require that all lots shown
on the plats shall be adaptable for the intended purposes without
danger to health or peril from flood, fire, erosion, or other menace.

(c)  If portions of the Master Plan contain proposals for drainage
rights-of-way, flood areas in fee, schools, parks, or playgrounds
within the proposed subdivision or in its vicinity, or if standards
for the allocation of portions of subdivisions for drainage rights-of-
way, flood areas in fee, school sites, park and playground purposes
have been adopted, before approving subdivisions the Planning
Board may further require that such drainage rights-of-way, flood
areas in fee, school sites, parks or playgrounds be shown in locations
and of sizes suitable to their intended uses. The County Commis-
sioners shall be permitted to reserve the location and extent of school
sites, public parks and playgrounds shown on the Master Plan or
any part thereof for a period of one year after the approval of the
