Storm Drainage Area Plan
20.
Drainage Area Plans
Watershed Area
The watershed area for the site shall be determined from contour plans
and shall include all lands that naturally drain into the system and any
fringe areas not accommodated in adjacent storm drainage systems, as
well as other areas which may become tributary due to regrading. The
information shall be confirmed with the City prior to the start of the design
of the internal servicing of the site.
External Areas
A plan shall be prepared to a scale of 1:1000 or 1:2000, depending on
the size of the watershed area, to show the nature of the drainage of the
lands surrounding the development site and to accurately delineate all
external drainage areas that are contributory to the drainage system for
the development. The external drainage areas shall be divided into
smaller tributary areas and the area and the location to which the
tributary area is considered in the design shall be clearly shown. The
plan shall clearly show all existing contours used to justify the limits of
the external drainage area.
In lieu of precise information on development on the whole or any part of
a watershed area, the latest zoning by-law and Official Plans issued by
the Planning & Development Department shall be used for all external
areas in the design and to determine the specific areas to which these
values apply.
Internal Drainage Area Plan
All internal storm drainage plans shall be prepared to a scale of 1:500
and shall include all streets, lots, blocks, rights-of-way, easements and
other lands within the development or capital improvement project. The
proposed storm sewer system shall be shown on this plan with all
manholes numbered consecutively from the outlet.
These manholes shall be the tributary points in the design, and the area
contributing to each manhole shall be clearly outlined on this plan. The
area, in hectares, of each contributing area (rounded up to the nearest
tenth of a hectare) and the runoff coefficient used shall be shown in a
SS-3
circle located within the contributing area indicated on a General Plan
and called a Storm Drainage Plan. In cases where areas of different
runoff coefficients may be tributary to the same manhole, the areas and
the coefficients shall be separately indicated on the plan.
In determining the tributary area to each manhole, the proposed grading
of the lots must be considered to maintain consistency in the design.
In the case of large areas under single ownership or blocks requiring
future site plan agreements, the design shall be prepared on the basis of
the whole area being contributory to one manhole in the abutting storm
sewer unless more than one private storm connection is necessary to
serve the property in which case the appropriate area tributary to each
connection shall be clearly shown and taken into account in the storm
sewer design.
The length, size and grade of each section of storm sewer shall also be
shown on the storm drainage plan.
Where the major and minor system drainage areas differ due to grading,
separate major and minor system drainage plans shall be provided to the
specifications described above.

North arrow.
95.
A detail must be shown for all maintenance holes when any of the
following apply:
a) Benching differs from that shown on the Development Control
Design Standard Drawings.
b) Depth of maintenance hole requires additional reinforcing steel.
c) Length or diameter (across base) of maintenance hole exceeds
2400 mm.
d) Any maintenance hole not shown in the Development Control
Design Standard Drawings e.g., poured maintenance holes.
96.
Project the maintenance hole location perpendicular to the centre line
chainage and indicate the maintenance holes at this particular chainage

upstream side of the maintenance hole.
99.
All maintenance holes shown in the profile must indicate all existing and
proposed inverts with each having reference to the North arrow.
Lockable maintenance hole covers shall be provided in park blocks and
open space blocks.
100. The maximum change in direction of flow in maintenance holes, for
storm sewer pipes 675 mm and over, shall be 45 degrees. For 675 mm
and larger diameter pipes where the change in direction is greater than
45 degrees, additional maintenance manholes 1200 mm diameter will be
required to reduce the angle.
101. The direction of flow in any maintenance hole will not be permitted at
acute interior angles.
102. Suitable drops will be provided across maintenance holes to compensate
for the energy losses due to the change in flow velocity and to
accommodate the difference in depth of flow in the upstream and
downstream sewers. When the pipe size does not change through a
maintenance hole and the upstream flow velocity does not exceed 1.5
SS-13
metres/second, the following allowances will be made to compensate for
hydraulic losses:
If alignment change is…
Straight Run
15 – 45 Degrees
45 – 90 Degrees
Junctions and transitionsa
Then drop required is…
Grade of sewer or 30 mm
30 mm – MOE minimum
75 mm – preferred
60 mm – MOE minimum
150 mm preferred
MOE Calculations
a
For all junctions and transition maintenance holes and when the upstream flow
velocity exceeds 1.5 metres/second, the drop required will need to be calculated
using the MOE Guidelines; “Hydraulic Calculations for Junction and Transition
Maintenance Holes”. Calculations for hydraulic losses will be included in the
design submission.
The engineer shall adhere to the following guidelines:
• Endeavor to keep entrance and exit velocities equal. In order to reduce
the amount of drop required, the engineer will try to restrict the change in
velocity from one pipe to another in a maintenance hole to less than 0.6
metre/second
• No acute interior angles will be allowed
• No decrease in pipe diameter from a larger size upstream to a smaller
size downstream will be allowed, regardless of an increase in grade
• When an increase in pipe size occurs at the downstream side of the storm
maintenance hole, match obvert elevations of the incoming and outgoing
pipes or have incoming pipe obverts higher than outgoing pipe obverts
103. The benching in all maintenance holes must not be less than 225 mm in
width at any point in the maintenance hole.
104. Maintenance holes shall have a maximum spacing of 110 metres for pipe
sizes 250 mm in diameter to 750 mm in diameter, a maximum spacing of
120 metres for pipe sizes 825 mm in diameter to 1200 mm in diameter
and a maximum spacing of 150 metres for pipe sizes greater than 1200
mm in diameter.
105. Maintenance holes shall be provided at each change in size, alignment,
slope and change in pipe material, at sewer junctions and at locations
that will ensure that the distance between maintenance holes will not
exceed the limits set out in Item No. 105.
106. As a condition of a functional system the owner shall conduct video
inspections of the underground storm sewer system required to be
constructed or installed and shall provide a colour digital video file record
and written report of those inspections to the satisfaction of the Director,
Planning & Development.
SS-14
107.
Should the video inspection in Item No. 107 detect pipe deflections then
plastic sewer pipes will be tested for deflection as per OPSS 410. Ring
deflection testing will be performed on all sewer pipes constructed using
plastic pipes. Pipes in sizes 250 mm to 450 mm in diameter will have an
allowable defelction of 7.5% of the base inside diameter of the pipe. The
test will be carried out a minimum of 30 days after the sewer trench has
been backfilled and installation of service connections or prior to paving
the roadways.
108.
If the plans are amended or altered after the Director,
Planning & Development has approved them the date of same shall be
noted in the Revision Block and resubmitted to the Director,
Planning & Development for approval.
109.
Final Measurement Sketch Form Sheets for sanitary, storm and water
systems, including storm sewer and rear lot catch basin easement
certification when applicable, are required to be received and approved
prior to the start of the maintenance period.
