(3) inches and blended in with the existing grade.
Specifications where applicable.
Topsoil shall be placed on the slopes to a minimum thickness of three
Top soil shall meet the requirements of Section 625 of the Standard
- Sod - All Sod shall consist of dense, well-rooted growth of permanent and desirable grasses indigenous to this area and shall
be practically free from weeds and undesirable grasses. At the
time the sod is cut, the grass on the sod shall have a length of
approximately two inches, and the sod shall be raked free of de-
bris.
The thickness of the sod shall be as uniform as possible;
in no case less than one inch, so that practically all of the
dense root system of the grasses will be retained but exposed
in the sod strip and so that the sod can be handled without un-
due tearing or breaking.
In the event the sod which is to be cut is in a dry condi-
tion so as to cause crumbling or breaking during cutting the sod,
apply water to it insufficient quantities to provide a well mois-
tened condition of the sod to the depth to which it is to be cut.
Sod shall be laid so that the joints caused by abutting ends
of sod strips are not continuous. Each sod strip shall be laid
snugly against the strip previously laid. Sod shall be laid in
such a manner that the longitudinal joint is offset from the
centerline of the ditch two to three inches towards the road. The
edges of all sod shall be covered with topsoil to assure good
growth.
Sod shall be staked in accordnace with the "Standard Speci-
fications." After staking has been completed, the surface of the
sod shall be cleared of all loose and foreign material.
The sod shall be laid to the grade specified by the City *
Engineer or his representative.
Since the sod will be lying in drainage ditches, it is
essential that the grade be maintained, and any deviation from
the specified grade shall be corrected by the Contractor at his
expense.
Care shall be taken that the sod is laid in such a manner
that no part of the soil is above a culvert flow line.
Seeding - All seeding shall be in accordance with the
"Standard Specifications" unless otherwise specified herein.
Written evidence of the mixture shall be submitted to the
City Engineer.
Seed mixture used shall conform to mixture number 1 as
designated in Section 630 of the "Standard Specifications."

seeding has been completed.
Watering - The landscaped areas shall be kept thoroughly
moist by watering or sprinkling, when rainfall is deficient,
for a period of ten (10) days.
Concrete Invert -
On all drainage easements and roadside ditches having a
slope less than 0.6% or greater than 5%.
The ditches shall be constructed as follows:

Public Works Comittedwidth of concrete bottom with an
18" width of sod on either side.
(2) Concrete thickness shall be 5" throughout unless
otherwise specified.
(3) Concrete shall be placed on a minimum of 3" of 3/4"
crushed stone.
(4) Topsoil, seed, sod and straw mulch on the backslope
of the ditch.
Cross Section
All inverts shall be constructed in accordance with the
typical cross section as shown. All invert intersections and
entrances shall be constructed in accordme with plans shown.
Sub-Grade
Sub-Grade under the concrete shall consist of 314" crushed

shall conform to Section 304.2.6 Gradation No. 2 for gravel of the
"Standard Specifications."

Flow Line Grade
Grade of the flow line of the invert shall be in strict
accordance with the grades submitted io and approved by the City I) Engineer and Public Works Committee.
Joints
a Transverse joints shall be constructed at right angles to
the centerline of the invert at intervals of ten feet. Joints
shall consist of a slot or groove at least one inch in depth
and one-fourth inch in width formed by inserting a parting strip
in the concret after it has been struck off. When sawed joints
are used, sawing of each day's pour shall be completed by midnight
of the same day unless otherwise directed by the Engineer. One
inch expansion joint filler shall be placed every 200 feet and
at end of the day's pour. Filler shall extend to the full
depth of the concrete and the top shall be slightly below the
