COST OF NEW LEVEE
Continued from page IL

is steep on each side and under the
Main street bridge, lay'up stone
wall with cement mortar.
From station SO to los build levee
on the new location with wall on
bedrock along the outer toe and the
face of the levee rdprapped with
large rock,
When the levee is extended later
from station 105 to the o. r. & n.
railroad, build a levee on the new To-
cation. To carry the riprap down to
bedrock on this section will be ex-
pensive and in my opinion it will not
be necessary If two cribs are put in
near the upper end to divert the cur
rent away from the levee.
BY repairing the toe of the levee
with large stone above the Main street
bridge, this part of the ievee would
probably stand any ordinary flood
but to make the levee safe against
such floods as occurred this year the
work should be done as outlined in
this report. II the work is done in
sections l to 4 inclusive it will pro-
tect all but the lower part of the city
which would be affected only by
back water from below the levee.
AS the material available for the
construction of the levee will not
make a water tight embankment,
there will be some seepage through
it and also through the gravel under
the levee. The seepage water can be
carried off through the surface
bitches on the sides of the streets to
the lower portion of the city: When
the levee is extended to the railroad
below the city a drainage pipe should
be placed through the railroad en-
bankment to let this water out.
The water from the mill race is dis
charged back into the river through
a masonry culvert under the levee at
station 69-75. The cost of putting in
an iron. gate at the lower end of the
culvert to prevent the high water
backing up through the culvert will
be about 1925.
Cost of Work in Detail.
The estimated cost of the work is
as follows:
Section No. l (present location)-
Excavating, 5000 cubic yards at 20
cents, $500; embankment, $500 cubic
yards at 90 cents, 5000: riprap. 24O0
square yards at 81, s24OO; stone ma
sonry $50 cubic yards at $3.50, 1915;
total, s4S75.
Section No. 2-Excavation, $500
cubic yards at 80 cents. s1Os0; riprap
2100 square yards, at 81, s2100; stone
masonry, $50 cubic yards. $3.50, s6,-
$40; total, s942O.
Section No. 3-Excavation, 1900
cubic yards. at 80 cents, 1850; riprap.
1900 square yards, at 81, $1,000; stone
masonry. 73O cubic yards, at $3.50,
s4745; iron gate, s225; total, s693O.
Section No. 4-Excavation, 1000
cubic yards. at 80 cents, $500; en-
bankment, 12,5O0 cubic yards, at 80
cents, 1880; riprap, $500 square
yards, at 81, $500; stone masonry,
$40 cubic yards, at $3.50, $685.; total,
s15,2O5.
Section No !-Embankment, 21,-
! 500 cubic yards at 20 cents, $4,000;
riprap, 54OO square yards, at 81,
s54OO; cribs, s225O; total. s11,95O.
Total of all sections, s4S.3SO.
p, Incidentals and contingencies, 81
| 900.
Engineering and supervision, s252O.
Total cost of work, $4,000,
If the levee is built on the new To-
cation on section l, the cost will be
approximately $12,500.
