only to manholes.
(c) All street pavements in subdivisions shall be bounded with combination
Portland cement concrete curb and gutter. The curb and gutter may
be deleted only with the permission of the Plan, Zoning and Development
Commission.
(d) Design of storm sewers shall be based on a flow computed on the basis
of the following formula:
Where:
|
Q
|
=
|
Stormwater runoff in cubic feet per second from the drainage
area.
|
C
|
=
|
A coefficient representing the ratio of runoff to rainfall,
C shall not be less than 0.35 for residential, 0.50 for multi-family
and 0.75 for business areas in small or short drainage systems.
|
I
|
=
|
The intensity of rainfall in inches per hour for a duration
equal to the time of concentration. The value of I will depend on
the rainfall intensity curve for the Elmwood Park vicinity in a ten-year
storm.
|
A
|
=
|
The drainage area in acres, including all tributary areas.
|
(e) Minimum velocity shall be two feet per second and the maximum velocity
shall be 10 feet per second.
(f) The minimum sewer size shall be 10 inches.

runoff which will come on the subject land from tributary lands through
natural watercourses. In calculating the runoff from tributary lands,
consideration shall be given to the character of the developed land
in determining the C factor. For undeveloped land the C factor shall
be no less than 0.35. Such designs shall provide adequate capacity
for receiving such drainage from tributary areas on a basis of the
ultimate development of such tributary areas. No increase in stormwater
runoff shall be directed to any existing watercourse or drainage system
unless the Village Engineer shall have determined that the receiving
watercourse or drainage system shall have adequate capacity to receive
such increased flow.
(h) All storm sewers and connection pipes between inlets, catch basins
and storm sewer which are constructed beneath existing or proposed
paving improvements shall be backfilled in lifts of 12 inches with
"stone screenings" or "trench backfill," as defined in the State standard

(3)
At no point in the swale shall the flow line be more than three
feet below the finished grade of the topsoil at the foundation of
the building opposite the swale.
(4)
No change in alignment of a backyard swale shall exceed 45°.
(5)
All such swales or drainage easement areas shall be sodded.
(j) Lots and blocks shall be so sloped in final grading that stormwater
runoff will be away from the building foundation and from the rear
of the lot to the proposed pavement or sewer system. Where swales
are allowed, only the runoff from the rear yard shall drain toward
the swale. Grading will be done so as to keep runoff from running
onto adjoining lots to a minimum.
(k) No sump pump shall be so installed and connected so as to discharge
stormwater runoff onto adjoining property or upon any street or public
way. Building construction on parcels which are proximate to storm
sewers shall cause footing drains from such structures to be connected
to the storm sewer system. Building construction on parcels which
are proximate to a retention pond may be required to cause footing
drains from such structures to be discharged into the retention pond
rather than to be connected to a storm sewer system.

inch per feet from house to the "Y."
(c) The sewer shall be constructed at such a grade as to insure a minimum
velocity of flow of two feet per second and a maximum velocity of
flow of eight feet per second. Sewer and water services, if in the
same trench, shall be separated by at least one foot vertically, the
water being higher, otherwise separate trenches must be used.
(d) Sewers shall be placed on public rights of way and shall at no time
be placed beneath and paralleling paving improvements except by special
permission of the Village Board of Trustees. If it is found necessary
to construct such sewers or services beneath pavements, or if such
sewers or services shall cross beneath existing or proposed pavements,
all trenches caused thereby shall be filled with "stone screenings"
or "trench backfill" placed in twelve inch lifts as defined by the
state standard specifications.
