it shall consist of rock mixed with cinders or river gravel or other
hard excavated material, thoroughly rammed and tamped in six (6) inch
layers and covered with a layer of three (3) inches of mining tailings
or river gravel, also thoroughly tamped and rammed to a uniform surface;

A. The specifications
for the construction of concrete sidewalks in the City, whether constructed
by the City or by other persons as hereinafter provided, shall be
as follows:
1. Materials.
a. Cement. All cement used in concrete sidewalks shall be of
a good grade of standard Portland cement, which will pass the standard
test specified by the State Highway Department. Any cement failing
to meet such test shall be removed from the work and not used in any
part thereof. The cement shall be delivered at the location of the
work in the original packages and protected so as not to be damaged
in any way before mixing with other materials.
b. Sand. The sand shall be a good grade of river sand or clean,
sharp flint sand, free from sludge, mud, soapstone or other impurities,
and shall be subject to the approval of the Superintendent of the
Department of Streets and Public Improvements.
c. Crushed stone. Crushed stone shall be any good flint or
limestone, crushed so as to pass a one (1) inch screen and rejected
over a quarter (¼) inch screen. All crushed stone must be free
from sand, dirt, sludge or other material which might be harmful to
the concrete.
d. Tailings. If mine tailings are used in the sidewalks, they
shall be of a good grade, free from sludge, mud or soapstone, and
shall be subject to the approval of the Superintendent of the Department
of Streets and Public Improvements.
2. Construction.
a. Subgrade. That portion of the street to be occupied by the
sidewalk shall be brought to a subgrade by excavation or embankment,
which subgrade shall be a true plane, parallel with, eight (8) inches
below and in true conformity with the sidewalk grade.
b. Foundation. The foundation shall consist of a bed of clean
tailings, cinders, broken stone, river or bank gravel, three (3) inches
in thickness and deposited on the subgrade.
c. Lower course. The lower course of the sidewalk, excepting
portions occupied by driveways, shall consist of a layer of Class
B concrete, four (4) inches in thickness after being tamped thoroughly.
The surface of the lower course shall be a true plane, one (1) inch
below and parallel with the finished grade of the sidewalk.
d. Finish course. The finish course of the sidewalk shall consist
of a layer of Class A concrete, one (1) inch thick after being floated
and neatly troweled to a true plane and smooth surface conforming
with the finished grade of the sidewalk, and deposited on the lower
course before the lower course has taken an initial set. A perfect
bond must be formed between the lower and the finished course.
e. Dimensions. Walks shall be of the width stated in this Chapter
or other City ordinances or specified in the plans and specifications.
The concrete in the finish and lower courses shall be laid in sections,
each section to be approximately six (6) feet long.
f. Artificial joints. Each section shall be separated from
the adjoining section by an artificial joint, made with a grover,
for the width of a section at right angles with the linear dimensions
of the walk, to the depth of the finished course, and by a sand joint
extending through the entire depth of the lower course. These joints
shall have a clear width of not less than one-eighth (1/8) of an inch
and be placed at intervals of not more than fifty (50) feet. A joint
having a minimum opening of one-half (½) inch in width shall
be provided and made in the manner above described.
g. Driveways. Where driveways are necessary across portions
of the park space, the driveway shall be built, in all respects, in
the manner above described for sidewalks; except, that the thickness
of the lower course shall be six (6) inches instead of four (4).
h. Class B concrete. Class B concrete used in the lower portion
of the sidewalks, as described above, shall be composed of approximately
one (1) part cement, four (4) parts mine tailings or crushed stone
and one (1) to two (2) parts sand. The governing clause of this specification
shall be as follows: Every cubic yard of Class B concrete shall contain
seven (7) sacks of cement, the proportions of sand, crushed stone
or mine tailings being varied according to the direction of the Superintendent
of the Department of Streets and Public Improvements, so as to produce
a concrete of the maximum density or strength.
i. Class A concrete. Class A concrete, as used in the finish
course of the sidewalks as described above, shall be composed of a
good grade of sand mixed with cement in the proportion of one (1)
part cement to one and one-half (1½) parts of sand.
j. Protection and curing. After the construction of the sidewalk
as specified above, the contractor or other person building such sidewalk
shall protect the work from damage by vehicles, pedestrians, animals
or anything which might damage the surface of the concrete, and the
sidewalk shall be kept thoroughly wet and protected from the sun during
hot weather for not less than six (6) days. The barricades or railings
provided to keep traffic off the sidewalk shall not be removed without
the permission of the Superintendent of the Department of Streets
and Public Improvements.
k. Weather conditions. No concrete sidewalk shall be constructed
by the City during weather which, in the opinion of the Superintendent
of the Department of Streets and Public Improvements, is unsuitable.
l. Removal of damaged or imperfect work. Upon the completion
of the work, should any of the sidewalk constructed as above specified
be found to be imperfect in any way, or to have been damaged by rain,
frost or any other cause, the contractor shall remove and reconstruct
any such damaged portion of the sidewalk, as directed by the Superintendent
of the Department of Streets and Public Improvements.
[R.O. 2012 §510.210; CC 1979 §27-45]
The stone used in gutters shall be of a good quality, free from
cracks, shelly places or damaging blotches and not less than three
(3) inches thick and three (3) feet long. The edges of the stone shall
be dressed to lay to a quarter (¼) inch joint for the full
length and thickness of the stone.
[R.O. 2012 §510.220; CC 1979 §27-46]
All sidewalks shall be laid to conform to a slope of one-half
(½) of an inch to the foot, rising from the curb line back
to the property line, except where there is a difference in the location
of the curb and the property line or where the intersecting grades
make it necessary to combine or change the same. These points shall
be set by the Superintendent of the Department of Streets and Public
Improvements and worked to by the contractor, according to the instructions
of the Superintendent of the Department of Streets and Public Improvements.
