HARRY W. NICE, GOVERNOR. 325

fore making his recommendation in writing with respect to
the construction or extension of any water or sewer lines or
systems, the Chief Sanitary Engineer shall make a thorough
field inspection of the territory proposed to be served by the
new construction or extension, and shall prepare sufficient
plans upon which to make an adequate cost estimate of the
proposed construction and/or extension, together with con-
servative estimates in writing of the assessable front footage
that will abut on the new or extended lines and the revenue
from front foot assessments to be expected therefrom. Such
plans and estimates shall accompany his written recommenda-
tions and shall be filed by him in the office of the Commis-
sioners. If said plans and estimates fail to show that the
proposed new construction or extension will be financially
self-supporting within a reasonable time after completion, the
Commissioners shall not order the construction of said new
lines or extensions, unless property owners requesting them
shall finance their cost upon a basis that will make them a
permanently self-supporting part of the Metropolitan District.

Section 335. For the purpose of paying the interest and
providing the sinking fund for the bonds issued by the County
Commissioners, as hereinafter provided for the water supply,
sewerage and drainage systems to be constructed, purchased
or established under this Act, the Commissioners are hereby
empowered and directed to establish a proper and reasonable
charge for connection with said water supply, sewerage and
drainage systems so to be constructed, purchased or estab-
lished as aforesaid, and to fix an annual assessment on all
properties, improved and unimproved, binding upon a street,
road, lane, alley or right-of-way in which a water main, sewer
or drain has been built. The said annual assessment shall be
made upon the front foot basis, and the first payment shall
be collectible during the year that the construction is started
on the water supply, sewerage or drainage system, or
in which the systems are purchased or acquired. And
interest at the rate of one-half of 1% per month shall
be charged on all said annual assessments remaining unpaid
60 days after said annual assessment shall be due and payable.
The Commissioners, for the purpose of assessing benefits, shall
divide all properties fronting upon a street, lane or alley, in
which a water pipe or sanitary sewer is to be laid, into four
classes, namely: First, Agricultural; second, Small Acreage;
third, Industrial or Business, and fourth, Subdivision Prop-
erty, and the benefit charges shall be fixed and levied in accord-
ance with the above classification; provided, however, that no
front foot benefit charge shall be levied against any agricul-
tural property until such property is connected with said
