struction of such storm water, surface drainage or flood control
projects or systems. Said bonds shall be dated, shall bear interest
at such rate or rates not exceeding eight per centum (8%) per
annum, shall mature at such time or times not exceeding forty
years from their date or dates, as may be determined by the Com-
mission, and may be made redeemable before maturity, at the
option of the Commission, at such price or prices and under such
terms and conditions as may be fixed by the Commission prior to
the issuance of the bonds. Such bonds may be issued in coupon or
in registered form, or both, as the Commission may determine,

(b)    The bonds authorized by the Commission to be issued here-
under at any one time for payment of the cost of storm water,
surface drainage or flood control projects or systems, including
the cost of any engineering or other surveys in connection there-
with, in that portion of the Washington Suburban Sanitary Dis-
trict situated in Prince George's County, shall constitute a separate
series from any other bonds of the District, and the proceeds there-
from shall be used for the aforesaid purposes in that portion of
the District. For the payment of the principal of and the interest
on the bonds of such series, and for the payment of the interest
on any notes issued under the provisions of subsection (c), below,
in anticipation of the issuance of any bonds of such series, the
County Council of Prince George's County shall levy annually
upon all of the property assessed for county tax purposes within
such portion of said Sanitary District in Prince George's County,
upon the certification of the Washington Suburban Sanitary Com-
mission, an ad valorem tax at a rate necessary to produce annually
the sum required to pay such principal and interest for the current
year, which tax shall be levied and collected as other Commission
ad valorem taxes are levied and collected and paid to the Commis-
sion. The bonds and any notes issued in anticipation thereof for
the purposes stated in this Section shall be guaranteed as to both
principal and interest by the County Council of Prince George's
County, and the County Council of Prince George's County is hereby
authorized and directed to guarantee said bonds and notes substan-
tially in the manner and form provided for guarantee of the con-
struction bonds of said Sanitary District. Such guarantee shall
operate as a pledge of the full faith and credit of Prince George's
County to the payment of the maturing principal of and interest
on said bonds and notes and, to the extent that the taxes above
provided for in this Section and any other moneys available or to
become available therefor (either through the issuance of bonds
or notes authorized hereunder or otherwise) are inadequate to pro-
vide the funds necessary to pay such principal and interest in any
year, said County Council shall levy upon all property subject to
taxation within Prince George's County ad valorem taxes in rate
and amount sufficient to make up any such deficiency.

(c)    The Commission is authorized and empowered to issue its
negotiable notes from time to time in anticipation of the issuance
of bonds authorized under this Section. Such notes may be issued
for periods not exceeding five years and may be renewed from time
