Metering
Replace Section
For all single family residential homes without fire
sprinklers the water meter setter size shall be 25mm
except in the case where there is a demonstrated need
for a larger meter. All other meters must be sized in
accordance with AWWA M22 and form contained in
Appendix A. It should be noted that this methodology is
based on the fixture value method and not the fixture
unit method employed in the BC Building Code for piping
within buildings.
The maximum operating range for a water meter shall be
less than 80% of the maximum instantaneous flow
capacity as outlined by the meter manufacturer, with a
maximum pressure loss of 48 kPa at the design flow rate.
The size selection must not compromise the operating
range or the long term life of the meter and must ensure
that pressures supplied to property are appropriate for
the intended use.
For developments that are proposed to be phased, the
meter chamber and piping must be sized for the meter
required for the ultimate buildout of the development.
However, the initial meter installed must also be sized to
accurately capture the range of flows for the first phase.
The Qualified Professional must ensure the meter
selection and installation requirements are appropriate
for the designed application.
A Qualified Professional must provide detailed sealed
drawings and shop drawings of the installation and
relevant
calculations,
to
demonstrate
the
appropriateness of the sizing of the meter, for approval
prior to installing the chamber.

4.1.1
Drainage Planning
Add Section 4.1.1 The Developer shall prepare such plans prior to
approval of the development applications. Such plans
shall provide an in-depth review of stormwater
opportunities and constraints on a specific watershed,
and take into consideration the potential impacts and
remediation measures for the affected watercourses.
Submission requirements for Developers are in
accordance with 2014 MMCD Design Guideline
Manual Stormwater Management Section 4.2:
Stormwater Control Plan.
4.1.2
Master Drainage
Plan
Add Section 4.1.2
The Master Drainage Plan (MDP), Watershed Plan
(WP) or Integrated Stormwater Management Plan
(ISMP) proposes an optimum drainage servicing
strategy that meets the ultimate land use in the
watershed. If a City MDP is not available,
developments with a cumulative phased development
area greater than 5 hectares are required to provide
an acceptable MDP. The proposed MDP must address
all identified constraints and provide the following
information as required:
§
Conceptual schemes for storm drainage
servicing including trunk storm sewers,
catchment detention ponds, minor and major
flow routes, and erosion protection.
§
Department of Fisheries & Oceans and BC
Ministry of Forests, Lands, Natural Resource
Operations and & Rural Development review.
§
Hydrological and hydraulic model of pre-
development and ultimate development
condition.
§
Bio-inventory of creeks and watercourses.
§
Hydrogeological Impact Assessment (in areas
where DFO and MOE jointly require its
consideration).
§
Inventory of watercourses and trunk drainage
facilities.
§
Sizes and performance requirements of
catchment detention areas.
§
Priority of MDP recommendations.

and
stormwater
management
"best
management
practices" (BMPs) designed to capture, convey, treat
or modify flows up to and including the 1 in 10 year
return period storm event.
4.3.2
The Major
System
Replace Section
Consists of surface flow paths, roadways culverts,
watercourses, and stormwater management facilities
designed to capture, convey, treat or modify larger
flows up to and including the 1 in 100 year return
period storm event.
If required to accommodate low building elevations,
and if approved, a piped minor system may be
enlarged or supplemented to accommodate major
flows.
4.3.3
Stormwater
Detention
Release Rates
Add Section 4.3.3
All stormwater detention facilities shall be designed to
limit post-development peak flows to equal to the
corresponding pre-development peak flows for the 1
in 2, 1 in 5, 1 in 10 and 1 in 25 year return period storm
events. Overland escape routes must be provided to
account for greater storms up to 1 in 100 year return
period in a manner which does not result in flooding
of any properties. Design rainfall intensities have been
increased by 15% as indicated in Section 4.4.
The total volume of runoff generated during storms
can also have a significant impact on receiving
watercourses. To the extent possible, the total runoff
generated from storms should be minimized through
the application of site adaptive planning and the use
of source controls. Site adaptive planning focuses on
limiting total imperviousness at development sites and
preserving natural features such as wetlands, forests
and native soils. Source controls focus on reducing
volume by retaining or enhancing opportunities for
infiltration and evapotranspiration on development
sites.
Discharge shall be controlled such that the
downstream watercourses receiving outflow from
detention facilities are protected from surcharge and
erosion. Where stability cannot be maintained,
measures to avoid or mitigate erosion shall be
proposed.

§
Hydrograph Method: Applicable for all areas
larger than 10 hectares, more hydrologically
complex catchments, and where stormwater
management systems require more than basic
conveyances.
The
computer
program
proposed for use is subject to approval by the
local authority. The program should be
selected to suit the complexity of the
watershed and the hydrologic processes that
need to be considered (e.g. detention,
groundwater
recharge
and
infiltration,
evapotranspiration, continuous simulation,
etc.) The most widely used programs (or
software packages) are those that are SWMM
based, however are constantly evolving, it is
inappropriate for this guide document to state
or endorse any particular ones.
§
Hydrograph Method: Applicable for complex
systems involving multiple catchments with
highly variable land use conditions, where
flow attenuation features are involved (eg.
detention pond, constructed wetland), or for
gross areas exceeding 10 hectares. Computer

Add to Section
Computer stormwater models shall utilize the 10 and
100 year return period design storm hyetographs
provided in Table 4.4.2. These hyetographs have been
derived using the Modified Chicago Distribution for a
24 hour storm duration. The hyetographs have also
been adjusted to reflect a 15% increase in rainfall
intensities.
Note: Performance of the drainage systems may be
under the influence of ocean levels and pump stations,
and
therefore

certain
conditions. Aside from the runoff analysis method

will be considered for approval at the discretion of the
City.
4.11.3 Dry Detention
Ponds
Add to Section
Design Details for Dry Ponds
Dry ponds are an effective method of stormwater
quantity control, and are typically not intended as
water quality improvement facilities. Dry ponds may
be constructed in areas where it is not feasible to
include a wet pond due to topography or site plan
constraints. Generally, dry ponds are used to control
larger, less frequent flows while allowing smaller flows
to pass through uncontrolled. A sedimentation
forebay is required upstream of dry ponds to promote
settlement of suspended solids.
a)
Land Dedication Requirements
Dry ponds to be operated by the City of Courtenay are
to be located on public property, which is to
CITY OF COURTENAY
STORMWATER MANAGEMENT
SUPPLEMENTARY DESIGN GUIDELINES
MARCH, 2018
SDG | pg. 22
encompass all lands subject to inundation from the 24
hour 1 in 25 year return period design high water level
and shall encompass all maintenance access roads as
outlined in Section i) below.
If the slope integrity may be jeopardized by cutting or
filling of priority lots, a restrictive covenant will be
placed on lots abutting the dry pond to control lot
development so as not to compromise design
requirements at the HWL. This is to ensure an
adequate freeboard is maintained.
b)
Minimum Pond Size
The City discourages the proliferation of large
numbers of small ponds, with the resultant higher
maintenance cost and lower efficiency impact. The
storage size is determined on the basis of outflow
control requirements as presented in this document.
c)
Frequency of Operation
All dry ponds shall be off-line storage areas designed
to temporarily detain excess runoff and thereby
reduce the peak outflow rates to the connected
downstream system. These facilities may be subject to
prolonged inundation during winter due to the rainfall
pattern in Courtenay.
d)
Drain Time
Ponds shall be generally designed to completely drain
within 40 hours of reaching maximum water surface
level, but in no case longer than 72 hours.
e)
Side Slopes
Side slopes subject to inundation upon filling of the dry
pond shall have a maximum slope of 4 (horizontal) to
1 (vertical) within public property. A freeboard
allowance of 0.6 m is required for all dry ponds.
f)
Depth of Ponding
The maximum live storage limit in a dry pond is for 3.0
m for the 1 in 25-year return period storm event and
CITY OF COURTENAY
STORMWATER MANAGEMENT
SUPPLEMENTARY DESIGN GUIDELINES
MARCH, 2018
SDG | pg. 23
1.5 m for the 1 in 10-year event, as measured from the
invert elevation of the outlet pipe.
g)
Bottom Grading and Drainage
The dry pond shall be graded to properly drain all areas
after its operation. The dry pond bottom shall have a
minimum slope of 0.5% and a slope of 0.7% or greater
is recommended where feasible. Lateral slopes for the
pond bottom shall be 0.5% or greater. French drains or
similar means may be required where it is anticipated
that these slopes will not properly drain the dry pond
bottom, or where dictated by multiple use or other
special considerations.
h)
Safety Provisions at Inlets and Outlets
All inlet and outlet structures associated with dry
ponds shall have grates provided over their openings
to restrict access. A maximum clear bar spacing of
0.150 m shall be used for gratings. Grated outlet
structures, are to be designed with a hydraulic
capacity of at least twice the required capacity to allow
for possible plugging. Further, the arrangement of the
structures and the location of the grating shall be such
that the velocity of the flow passing through the
grating will not exceed 1.0 m/s.
Appropriate fencing and guard-rails are to be provided
to restrict access and reduce the hazard presented by
structure head and wing walls.
i)
Maintenance Access Requirements
A minimum 4.0 m wide, all-weather vehicle access
shall be constructed from a public road to the inlet,
sediment sump, outlet, emergency overflow and other
works requiring maintenance. The maximum grade of
the access shall be 8%. The surface shall be finished
with gravel topped with path chip, geogrid, or rigid
grass suitable for all weather maintenance truck
access. A vehicle access route shall also be provided to
the edge of all stormwater management ponds
suitable to carry maintenance vehicles. This access
shall also extend to the pond static (normal) water
level. The access surface shall include a 1.0 m buffer
from top of pond and an additional 1.0 m from edge of
CITY OF COURTENAY
STORMWATER MANAGEMENT
SUPPLEMENTARY DESIGN GUIDELINES

access road to the edge of dedicated lands, and shall
be accessible from and extend to a public road right-
of-way. Sharp bends in this access route are to be
avoided.
Vehicle
turning
movements
must
accommodate a tandem axle 60,000lb flush truck and
tandem axle dump truck.
j)
Landscaping
Landscaping plans shall be submitted as part of the
Engineering Drawings for dry ponds, and the
completion of landscaping will be considered part of
the
improvement
construction.
The
minimum
requirement for landscaping of dry ponds shall be the
establishment of grass cover. Preference should be
given to use of native plant materials and, in no case,
should non-native, aggressive ("invasive") plant
materials be used.
k)
Sediment Control
Use of storm ponds for sediment control is acceptable
during construction of the first phase of a
development, and must be remediated prior to
acceptance of the Works and Services by the City of
Courtenay. The City may accept the use of storm
ponds for sediment control for multiple phases of a
development
if
the
appropriate
maintenance
agreement is established and the appropriate security
is provided by the developer. The required security is
125% of the estimated remediation cost.
l)
Operation and Maintenance Manual
Three copies of an operation and maintenance manual
shall be submitted when the facility is completed and
transferred to the Municipality and include:
§
Record drawings of the completed facility.
§
Brief description of the facility operation
including design flows, design depths, and
schematic diagrams of the inlet and outlet
structures, connections, controls, valves,
bypass, overflows, etc.

4.11.4 Wet Detention
Ponds
Add to Section
Design Details for Wet Ponds
Wet ponds are well suited for both quality and
quantity control of stormwater runoff. Wet ponds
incorporate a permanent pool which rises in response
to rainfall events. Extended storage durations and
strategic planting in the active storage zone can
further improve water quality. Sedimentation
forebays should still be incorporated upstream of wet
ponds for preliminary settlement of larger suspended
solids.
a)
Land Dedication Requirements
Wet ponds to be operated by the City of Courtenay are
to be located on Public property which is to
encompass all lands subject to inundation from the 24
hour 1 in 25 year return period design high water level
plus the edge treatment. This designation will also
apply to all rights-of-way for access to and protection
of inlet and outlet sewers and flow control facilities,
maintenance access routes to the pond, and to a
certain proportion of the lands fronting on the pond,
from the upper edge of the area containing the edge
treatment to the limit of the water's edge when the
water surface is at the design high water elevation.
A restrictive covenant and/or a limit for the Minimum
Building Elevation (MBE) will be placed upon those lots
abutting the pond to guide lot development that
design requirements of the stormwater storage facility
are not compromised and that an adequate freeboard
is maintained.
b)
Minimum Pond Size
The City discourages the proliferation of large
numbers of small ponds, with the resultant higher
CITY OF COURTENAY
STORMWATER MANAGEMENT
SUPPLEMENTARY DESIGN GUIDELINES
MARCH, 2018
SDG | pg. 26
maintenance cost and lower efficiency impact. The
storage size is determined on the basis of outflow
control requirements as presented in this document.
c)
Drain Time
Ponds shall be generally designed to drain to normal
water surface level within 40 hours of reaching
maximum water surface level, but in no case longer
than 72 hours.
d)
Side Slopes
Areas covered by water, from the design high water
level down to the normal water level shall have a
maximum slope of 7 (horizontal) and 1 (vertical) and
extend at a maximum slope of 7:1 (H:V), from normal
water level to a depth of 0.43 m (i.e., a distance of 3 m
horizontally into the pond for safety needs). Steeper
side slopes, up to 4:1 (H:V), may be considered for
areas separated from the public by a Concrete Rail
Fence. A slope of 4:1 (H:V) shall be used from the 0.43
m depth point (below normal water level) to the pond
bottom.
e)
Minimum Depth
The minimum depth from normal water level to pond
bottom (beyond the side slope area) shall be 1.5 m.
The maximum live storage limit in a wet pond is for 3.0
m for the 1 in 25-year return period storm event and
1.5 m for the 1 in 10-year event, as measured from the
invert elevation of the outlet pipe. A freeboard
allowance of 0.6 m is required for all wet ponds.
f)
Pond Bottom Material
For areas where the ground water table is below the
Normal Water Level (NWL), the pond bottom and side
slopes are to be composed of impervious material with
a suitably low permeability (e.g. with a permeability
coefficient in the order of 1 x 10-6 cm/s).
For areas where the groundwater table is expected to
be near or above the NWL, the pond bottom may be
of a pervious material as dictated by geotechnical
considerations.
CITY OF COURTENAY
STORMWATER MANAGEMENT
SUPPLEMENTARY DESIGN GUIDELINES
MARCH, 2018
SDG | pg. 27
g)
Circulation Requirements
Narrow and/or dead bay areas where floating debris
may accumulate are to be excluded at the design
stage. Inlets and outlets should be located with
consideration of the need to maximize detention time
and circulation within the pond water body.
h)
Inlet and Outlet Requirements
§
Submergence of Inlets and Outlets
Inlet and outlet pipe inverts are to be a minimum
0.1 m above the pond bottom. Forebays are to be
constructed on pond bottom to accommodate
extra depth requirements for placing inlet/outlet
structures, as required.
§
Provision for Free Outfall from Inlets to Ponds
Where feasible, the invert elevation at the first
manhole upstream from the pond in a minor
system or the connecting or interconnecting pipe
system, shall be at or above the normal water level
of the pond to avoid deposition of sediments in
the inlet pipe. To avoid backwater effects on the
upstream sewers leading to the pond, the obvert
of the inlet sewer at the first manhole upstream
from the pond shall be at or above the pond level
for the 1 in 10-year return period storm event. A
drop structure upstream from the pond will
generally be required to achieve this. "Inlet" and
"outlet" control calculations are required to verify
the mode of operation of the pond inlets. In cases
where grades set limits on the above, special
maintenance
needs,
such
as
periodic
flushing/cleaning must be identified.
§
Provisions for Water Level Measurements
To permit direct measurement of water level in
the pond, a manhole is to be provided
hydraulically connected to the pond such that the
level of water in the manhole will mimic the pond
water surface level.
CITY OF COURTENAY
STORMWATER MANAGEMENT
SUPPLEMENTARY DESIGN GUIDELINES
MARCH, 2018
SDG | pg. 28
§
Provisions for Lowering the Pond Level
The provision of the means to drain the pond
completely by gravity drainage is desirable. Where
a gravity drain is not feasible, provisions are to be
made in association with the outlet works or
otherwise, so that mobile pumping equipment
may be installed and used to drain the pond.
i)
Sediment Removal Provisions
The pond design shall include an approved
sedimentation removal process for control of heavy
solids, which may be washed to the pond during the
construction period associated with the development
of the contributing drainage catchment.
Sediment basins shall be provided at all inlet locations
for continued use after completion of the subdivision
development. Stormwater storage/detention ponds
shall not take the place of a development's sediment
control storage basin.
j)
Pond Edge Treatment
Edge treatment or shore protection is required and
shall be compatible with the adjacent land use. The
treatment
used
shall
meet
criteria
for
low
maintenance, safety and habitat requirements. The
edge treatment is to cover ground surfaces exposed or
covered by water during a pond level fluctuation to 0.3
m below or above the normal water elevation, and
shall be adequate to prevent erosion of the pond edge
due to wave action. The typical acceptable edge
treatment shall be, but is not limited to, a 250 mm
deep layer of well graded washed rock with a 75 mm
minimum size or alternatively appropriate edge
vegetation.
k)
Maintenance Access Requirements
A minimum 4.0 m wide, all-weather vehicle access
shall be constructed from a public road to the inlet,
sediment sump, outlet, emergency overflow and other
works requiring maintenance. The maximum grade of
the access shall be 8%. The surface shall be finished
CITY OF COURTENAY
STORMWATER MANAGEMENT
SUPPLEMENTARY DESIGN GUIDELINES

with gravel topped with path chip, geogrid, or rigid
grass suitable for all weather maintenance truck
access. A vehicle access route shall also be provided to
the edge of all stormwater management ponds
suitable to carry maintenance vehicles. This access
shall also extend to the pond static (normal) water
level. The access surface shall include a 1.0 m buffer
from top of pond and an additional 1.0 m from edge of
access road to the edge of dedicated lands, and shall
be accessible from and extend to a public road right-
of-way. Sharp bends in this access route are to be
avoided.
Vehicle
turning
movements
must
accommodate a tandem axle 60,000lb flush truck and
tandem axle dump truck.
l)
Landscaping Requirements
Landscaping plans for areas bounding the pond shall
be submitted as part of the Engineering Drawings.
Landscaping of all proposed public lands included for
purposes of the pond and of all proposed lands
dedicated to the City for storm ponds on proposed
private property, including all areas from the pond
edge treatment to the limit of inundation when the
pond is filled to the design high water level, is to be
part of the pond construction requirement. The
minimum requirement for landscaping shall be the
establishment of grass cover. Native plant materials
must be used.
m) Sediment Control
Use of storm ponds for sediment control is acceptable
during construction of the first phase of a
development, and must be remediated prior to
acceptance of the Works and Services by the City of
Courtenay. The City may accept the use of storm
ponds for sediment control for multiple phases of a

CITY SCADA SYSTEM
City of Courtenay sewage pumping stations are to be compatible with a central monitoring system,
planned for some future date. This section is provided to explain the requirements on all new lift stations
in order to ensure compatibility with the planned SCADA system.
Key features of the planned SCADA system are planned to include:
·
real time information regarding the status of stations throughout the municipality in order
to efficiently respond to faults and other issues as they arise;
·
limited remote control capability of the stations, which in certain cases may avoid the need
for a site visit;
·
historical information and other data that will assist with proactive maintenance activities;
and
·
