city, but shall apply to any and all other property necessary for the pur-
poses of this Act which may, at the time of condemnation, be subject to a
prior public use for water supply, sewerage and drainage systems.

1924, ch. 539, sec. 4. B. Co. C. (1928), sec. 330.

330. As soon after organization as possible, and from time to time
thereafter, the Commissioners shall cause surveys, studies, plans, specifica-
tions and estimates to be made for water supply, sewerage and storm-water
drainage systems in all those parts of the Baltimore County Metropolitan
District in which there is, in their judgment, a need for water supply,
sewerage or drainage. The Commissioners shall divide the Metropolitan
District into water, sewerage or drainage sub-districts in such a way as
shall in their judgment best serve the needs of the various communities
and shall promote convenience and economy of installation and opera-
tion, which sub-districts when so created shall be numerically designated
in the order of their creation as Metropolitan Sub-districts, and shall
thereafter be known by the designations so given. Whenever and as plana
are completed for those sub-districts most needing service, the Commis-
sioners shall give notice by publication for two successive weeks in one
or more newspapers published in Baltimore County that said improve-
ments are contemplated, that the boundaries of the sub-districts have been
established and the classifications provided for in Section 335 hereof,
have been made, and that a time specified in said notice which shall be
at least five days after the expiration thereof, any persons interested in
said improvements will be heard. After public hearing, however, the
decision of the Commissioners as to the areas to be included and improve-
ments to be carried out in any sub-district shall be final. Such surveys,
studies and plans shall be made in consultation and co-operation with the
Chief Engineer of Baltimore City. Whenever plans shall have been com-
pleted for a water supply, sewerage or storm-water drainage system, or
any part thereof, in any part of the District the Commissioners shall pro-
ceed to construct or cause to be constructed such systems, or parts thereof,
by contract, after public advertisement, or by day labor, if no satisfactory
contract can be made after public advertisement, as they may deem ad-
visable, so that said system or systems may be constructed at a minimum
cost, provided, however, that the cost of such work carried out by day
labor shall not exceed, at any one time, twenty-five hundred dollars
($2500.00). And provided further, that no hearing or notice and adver-
tisement thereof shall be required in case all parties interested in any
particular extension of a water supply line file with the Commissioners
a request in writing for such extension.

331. The proper authorities of Baltimore City are hereby empowered,
authorized and directed to make extensions of water supply lines for and
in the Metropolitan District whenever and wherever requested in writ-
ing by the Commissioners of Baltimore County. Such extensions shall
