FOR PAVING OF SIXTH STREET
FROM L STREET TO BRIDGE
PLANS FOR SUPERIOR JOB
Mr.. Hobson Carefully Explains How
the Work VIII BE Done and
Its Cost.

The property owners on South
Sixth street from l. street to the
bridge are asking for full information
in regard to paving that part of the
street with standard macadam and
the Courier bas taken considerable
trouble to secure reliable informa-
tion. In preparing plans for the i'm
provement of any street or roadway
by grading, graveling, matchmaking
or paving with any of the modern
hard or waterproof surface pave
ments, it is necessary in every case
to first take into consideration the
drainage of the surface or storm
water into and away from the road
way to be improved. When this
question is settled, there must be
careful examination of the material
which forms the natural road bed,
which shall be made into sub
foundation for the improvement. The
classification of the natural road
bed has to do with the slope of the
sub-foundation from the sides to the
center, and also the nature of the
sub-foundation controls the size and
mixture of the foundation material
The slope endwise of the roadway
may lessen or increase the necessary
slope from the center or crown to
the gutter, which may again affect
the size and quantity of the material
used upon the bottom. These grades
are to be determined in such man
ner as to best conform to the adjoin-
ing property along either side of the
street.
In preparing the plan and specifi-
cations for the Improvement of South
Sixth street from L street to the
Rogue River bridge, by laying along
either side a concrete curb and gut
ter, and along the roadway, "a feet
in width, a standard macadam, the
foregoing points have been carefully
considered, and the following extract
of the city engineers report to the
city council is the result

and thoroughly rolled with a twelve
ton steam roller, and any soft OF
springy places found In the grount
after rolling shall be removed anc
filled with rock gravel or concrete
until the same shall become solid BY
rolling.
8. Foundatlon-.-Upon the sub
