(a)
notwithstanding a requirement to provide or upgrade a road to the
standard required for an Arterial street within or adjacent to a subdivision
or development, direct vehicular access to individual parcels of land shall

vehicular access by the additional construction of lower classification
roads or by lanes unless, in the opinion of the Approving Officer,
construction of such additional access is not feasible;
(b)
streets shall be located and aligned so that each parcel abuts a street on
one side only except where there is an intersecting street abutting a corner
lot, or where, in the opinion of the Director, it is necessary:
i)
to provide access to other parcels;
ii)
to provide a consistent or continuous pattern of streets; or
iii)
to complement a future pattern or subdivision;

sanitary sewer systems may be waived at the discretion of the Director if
Subdivision and Development Servicing Bylaw No. 2589, 2013
8
City of Pitt Meadows
#125335v1
approval is obtained from the authority having jurisdiction over on-site sewage
disposal or discharge to bodies of water.
7.12 Despite Section 7.2, a subdivision of not more than 3 lots all abutting an existing
highway with adequate ditches, may be exempted from the requirement for piped
storm drainage at the discretion of the Director who may approve drainage
connections directly to the existing ditch where the construction of a piped storm
drainage system is not technically feasible at the time of application.
8.0
EXCESS OR EXTENDED SERVICES
8.1
The Director may require a Developer to provide excess or extended services to
land other than the land being subdivided or developed. The cost to the City of
providing any such excess or extended services is considered to be excessive
and must be paid by the Developer. If the Developer provides a highway or
waterworks, sewage or drainage facilities that serve land other than the land
being subdivided or developed, the Developer will be paid charges collected from
owners of other benefiting land as a condition of connecting to, or using, the
excess or extended services. The Developer shall provide studies; drawings and
cost estimates prepared by the Consulting Engineer necessary to assist the City
in determining the charges. The charges will include interest calculated annually
at a rate established by bylaw, payable for the period beginning when the excess
or extended services are certified as completed by the Director to the date when
the connection is made or use begins. Charges will be collected up to a date
agreed by the Developer and the City but not for more than fifteen (15) years.
9.0
WORKS COVERED BY DEVELOPMENT COST CHARGES
9.1
Any part of the cost of works required under Sections 7.5 or 7.6 that has been
included in the calculations for a development cost charge bylaw shall be paid
from the appropriate development cost charge reserve fund. If there are
insufficient funds available for the City's share of the cost and if the Approving
Officer considers the cost to the City would otherwise be excessive and would
therefore refuse to approve the subdivision, the Developer may agree to provide
the works and services. If the Developer so agrees, the actual certified costs
shall be deducted from the class of Development Cost Charges applicable to that
service.
10.0 PARK LAND
10.1 The Approving Officer shall determine whether park land is to be provided or a
payment is to be made in accordance with section 941 of the Local Government
Act taking into account whether there is sufficient land in the vicinity of the
proposed subdivision for public park and open space. The Approving Officer
shall determine the location of any park land to be provided.

City of Pitt Meadows
#125335v1
11.0 EXEMPTIONS
Servicing requirements may be waived where:
11.1 a proposed subdivision does not create any additional parcels and only results in
highway or park dedication or an adjustment of boundaries between existing
parcels; or
11.2 where a parcel is to be created solely for the use of unattended equipment
necessary for the operation of:
a)
a community water or sewer system;
b)
a gas or oil transmission or distribution system;
c)
a radio or television receiving antenna;
d)
a telecommunication relay station;

a similar facility,
and the Developer enters into a covenant with the City in a form satisfactory to
the City's solicitor and upon registration in the Land Title Office the covenant has
the effect of preventing the land being used for any other purpose without the
approval of the City.
12.0 RIGHTS OF WAY AND EASEMENTS
12.1 The Developer must grant, or acquire, statutory rights of way in favour of the City
in such locations and with such dimensions as necessary to accommodate works
required to serve a subdivision or development and for protection against
drainage problems as a result of subdivision or development and the right of way
must be in a form acceptable to the City's solicitor.
12.2 Where it is not practical to service an individual parcel from a highway, the
Developer must grant, or acquire, easements for servicing of individual parcels, if
acceptable to the Director, in favour of the benefiting parcel and covenant with
the City, in a form acceptable to the City's solicitor, that the easement will not be
altered or discharged without the approval of the City. No more than one parcel
shall be served by this means across any other single parcel.
12.3 Rights of way and easement documents must be deposited and registered in the
Land Title Office before the subdivision plan is signed or the building permit
issued. Alternatively, the Developer may provide a solicitor's undertaking,
satisfactory to the City's solicitor, that the subdivision plan and rights of way
documents will all be deposited in the sequence required by the City's solicitor
Subdivision and Development Servicing Bylaw No. 2589, 2013
10
City of Pitt Meadows
#125335v1
and that, if that is not possible, the subdivision plan will immediately be returned
directly to the Approving Officer.
12.4 If works required in accordance with this Bylaw will cross an established
easement or other right of way, the Developer must, at his own expense before
permission to proceed with construction is granted, obtain any amendments
necessary to permit the construction, reconstruction, inspection, operation,
repair, maintenance and use of the works under conditions acceptable to the
Director.
13.0 COMMENCEMENT OF CONSTRUCTION
No land clearing, stripping of topsoil, excavation, placement of fill, construction or
installation of any kind, other than required for site investigation, may be undertaken on
a subdivision or development site until the signed Commitment by Developer and
Consulting Engineer, a signed Servicing Agreement and all applicable fees, and
necessary approvals of all other agencies have been received by the Director, and the
Director has stamped the drawings as accepted and issued Permission to Commence
Construction all in accordance with Schedules C and D.

Bylaw at the expense of the Developer, all obligations of the Developer and
Consulting Engineer set out in Schedule D must be fulfilled as evidenced by the

acceptable to the City's Director of Finance and Facilities as security; and
b)
enters into a Servicing Agreement with the City, substantially in the form of
the Sample Servicing Agreement contained in Schedule E, to complete the

14.3 The amount of security required in Section 14.1 shall be the greater of 120% of
the cost of the works remaining to be completed or 25% of the total cost of the
works required for the subdivision or development. The cost shall be estimated
in detail by the Consulting Engineer and accepted by the Director and include
engineering, landscape architect services, inspection, testing, construction and
installation of all works and all associated taxes.
14.4 Partial refunds of the security will be made based on the proportion of the works
completed, inspected, and, if required, tested all in accordance with certified,
detailed progress reports submitted by the Consulting Engineer or Landscape
Architect and approved by the Director. Partial refunds will not be made more
frequently than once per month and will only be permitted to a maximum of 90%
of the value of the works completed. Any costs incurred by the City which are
recoverable from the Developer will be deducted from any partial refund
regardless of whether the recoverable amount relates to the same works as the
partial refund. Despite the forgoing, the City will retain not less than 15% of the
total cost of the works required until a Letter of Substantial Completion has been
issued and all project record documents have been submitted to the satisfaction
of the Director in accordance with Schedule D Section 1.24 and then not less
than 10% of the total cost of the works until the Director has issued a Letter of
Final Acceptance. Thereafter refunds will be made for completed boulevard
landscaping until a Street Tree Installation Certificate has been issued and then
10% of the cost of those works will be held until the Director issues a Street Tree
Final Certificate.

Schedule C: Design Criteria
C6
Subdivision and Development Servicing Bylaw No. 2589, 2013
City of Pitt Meadows
#125335v12
PART A:
GENERAL
A.1
COMMON DESIGN NOTES
A1.1
Introduction
Schedule C sets out the criteria to be used for the design of Works required under the
Bylaw.
For the purposes of Part A, the term Design Professional is used to refer to the Consulting
Engineer and the Landscape Architect where either or both are appropriate in the context.
The Consulting Engineer shall be responsible for overall coordination of design and
ensuring no conflict exists between landscape design and engineering design or any
existing municipal or other Works.
A1.2
Design Criteria
Where conditions arise which are not covered by Schedules C or D, the Design
Professionals shall consult with the Director prior to completing the design.
The first submission of the Design Drawings shall be accompanied with a declaration from
the Design Professionals that the design of the proposed works is in general conformance
with this Bylaw. Exceptions to general conformance shall be noted and documentation
provided to explain the noted exceptions.
A.1.3 Sealing of Drawings
The Design Professional's seal on the design drawings submitted to the Director for review
and acceptance will certify that the design has been carried out in compliance with the
Bylaw and in accordance with the best current acceptable engineering and landscaping
standards and practices.
A.1.4 Design Drawings
All Design Drawings prepared by the Design Professionals for submission to the Director
shall conform to the minimum drawing standards specified in Section A.4 of this Schedule.
A.2
APPROVAL PROCEDURE
A.2.1 Works Required
Following favorable review of an application for subdivision by the Approving Officer, or for
a building permit by the Building Inspector, submitted with all required fees and a
conceptual servicing plan prepared by the Consulting Engineer and receipt of all required
fees and of the signed Commitment by Developer and Consulting Engineer, the Developer
will be provided with a preliminary list and general description of Works required to be
constructed under this Bylaw. The preliminary information provided by the City is
Schedule C: Design Criteria
C7
Subdivision and Development Servicing Bylaw No. 2589, 2013
City of Pitt Meadows
#125335v12
intended only as a guideline to the Developer and does not necessarily represent a final
and complete list of all necessary requirements. The Developer will provide this
information to the Design Professionals who may request further information or
clarification of the requirements prior to commencing design. Additional requirements
may be identified by the City during or following completion of the initial design.
A.2.2 Initial Design
Upon receipt of preliminary requirements, the Consulting Engineer shall arrange for all
legal and/or topographic surveys, geotechnical investigations, traffic studies, and any other
investigations, including test pits if necessary to confirm the location of underground
utilities, required to prepare the design drawings. The Consulting Engineer shall be
responsible for confirming the accuracy of any information about existing Works or other
municipal infrastructure provided by employees of the City.
The Consulting Engineer shall perform all necessary calculations and field verifications to
confirm that the proposed design of the Works conform to the Bylaw. Deviations from the
preliminary requirements may be accepted, providing they accomplish the same purpose
and are agreed to by the Director.
A.2.3 Submission of Design Drawings
Prior to submission of Design Drawings, the Developer and the Consulting Engineer must
jointly submit the Commitment by Developer and Consulting Engineer. The Consulting
Engineer shall submit a minimum of two complete sets of sealed paper prints of the design
drawings, including those prepared by the Landscape Architect, to the Director for review.
A.2.4 Unacceptable Design Drawings
If design drawings are not acceptable to the Director, one marked-up set of drawings will
be returned to the Consulting Engineer for correction and/or revision.
A.2.5 Resubmission of Design Drawings
The Consulting Engineer shall submit a minimum of two complete sets of sealed paper
prints of the revised design drawings to the Director for review plus additional prints of
individual design drawings as may be required by the District for ancillary purposes.
A.2.6 Approvals of Other Agencies
The Consulting Engineer shall obtain all necessary approvals from all other agencies that
may be involved and submit them to the Director before the design drawings can be
stamped as reviewed and accepted by the City. These agencies may include, but are not
necessarily restricted to, Federal and Provincial Fisheries, Ministry of Environment, Metro
Vancouver, Fortis Gas, Telus, B.C. Hydro, and the National Energy Board. Where an
application to an agency must be made by the City, the Consulting Engineer shall supply
Schedule C: Design Criteria
C8
Subdivision and Development Servicing Bylaw No. 2589, 2013
City of Pitt Meadows
#125335v12
the City with the necessary copies of drawings and any other supporting information for
the application.
A.2.7 Acceptance of Design Drawings
Upon notification that the design drawings are acceptable to the Director, the Consulting
Engineer shall submit five complete sets of sealed paper prints. One set will be stamped as
having been reviewed and accepted by the City and returned to the Developer. The
stamped drawings are the Contract Drawings as defined in this Bylaw.
The Director's review of the design drawings is to check for general compliance with the
Bylaw and the subdivision requirements. The Director's stamp does not certify the
accuracy or appropriateness of the design nor transfer any responsibility for proper design
to the Director or the City. The Design Professional shall be fully responsible for the
accuracy and suitability of the design and for its conformity to the Bylaw. Any design
errors and/or omissions, when so ever discovered, shall be rectified at the cost of the
Developer.
The stamping of the design drawings does not constitute subdivision approval, nor does it
permit construction, or any other work on site, to be commenced.
A.2.8 Other Utilities
The Consulting Engineer shall arrange for the coordination of the design, location and/or
relocation of non-municipal utilities with B.C. Hydro, Telus, Fortis Gas, Shaw cable, and any
other appropriate utility companies.
A.3
UTILITY ALIGNMENTS
A.3.1 General
Wherever practical, utility alignment shall conform to the offsets illustrated in the City's
Typical Cross Section Drawings No. 101A to 101G in Schedule D for the class of road being
constructed.
Where the standard offsets are not practical due to existing utilities in the ground or other
considerations the following principles shall apply to the choice of alignment:
a) where feasible, no utilities to be located directly under or within 0.5 metres of the
curb or sidewalk alignment;
b) manholes to be out of wheel paths on the roadway; and
c) minimum clearance from face of curb to any fixed object to be 0.3 metres.

NOTES to Table B13: Minimum Standards for Roadwork's
1.
Selection of the road design criteria set out in Table B13 shall be based on the predominant
permitted land use for new development adjacent to the road and the road classification. Where the
predominant permitted land uses for new development are different on opposite sides of a road, the
greater of the applicable road widths shall be required.
2.
If one side of a road of any classification is predominantly urban and the other rural, the urban side
must have curb, gutter, sidewalk, boulevard landscaping and trees in accordance with the relevant
Supplementary Detail Drawings 101A to 101E, but the rural side may be constructed with shoulders
and ditches in accordance with drawing 101F. Where urban uses are predominant on both sides of
a local road but a multifamily or institutional use is the predominant use on only one side, a sidewalk
will be required on that side only. In these cases, right of way widths may be adjusted accordingly.
3.
The design speed governs vertical and horizontal geometrics. Values of all parameters shall be
taken from the latest edition of the Transportation Association of Canada manual Geometric Design
Guide for Canadian Roads.
4.
Local Urban Roads of 8.5 m width may be constructed within a 12 m right of way for compact
residential developments of 25 units/hectare or greater as shown on Drawing 101B:
a)
on short connecting blocks where, because all parcels also abut other roads, underground
wiring and gas mains are unnecessary; or
b)
if the Developer acquires or grants statutory rights of way in favour of the utility companies
for the installation of underground wiring and gas mains.
5.
Where there is insufficient standard boulevard width to accommodate transformers between curb
and sidewalk in accordance with BC Hydro requirements, the sidewalk shall be located further from
the curb at that location and the road right of way shall be widened as necessary.

1,400 litres per capita per day for residential areas, and 90,000 litres per hectare
per day for commercial, institutional and industrial areas plus the applicable fire
demand at a location where the pressure drop would be most critical.
Despite a) and b), where zoning or a development permit determines a specific type of
commercial, institutional or industrial land use, water demand may be based on generally
accepted data for the type of use taking into account the greatest water demand that may
be required for the permitted use on any part of the land.
C.1.2 Fire Demand

PART E:
STORM DRAINAGE SYSTEM
E.1
DESIGN METHODS
E.1.1 Stormwater Management Plan
A Storm Water Management Plan shall be submitted for a subdivision or development in
accordance with this Section, and as set out in Section A.4, except for:
a)
a subdivision or development within an area subject to, and which meets the
requirements of, a watershed or integrated stormwater management plan
adopted by Council;
b)
a subdivision in accordance with single or two family residential zoning which
does not require the construction of a road and which can be served by
extensions of existing minor and major drainage systems that have adequate
capacity;
c)
a building permit for a single or two family dwelling; or
d)
a building permit, other than for a single or two family dwelling, on a parcel no
greater than 1100 m2.
A Storm Water Management Plan shall include a statement describing how the criteria in
E.2.2 are to be achieved.
Storm drainage systems shall be designed using either the conventional method or the
stormwater management method.
E.1.2 Conventional Method
Design shall be based on the Rational Formula. This method shall only be used for the
design of minor systems with storms of 1 in 10 year return serving a watershed of 8 ha or
less and only if the Director is of the opinion that the downstream minor and major
drainage systems have adequate capacity.
E.1.3 Stormwater Management Method
This method utilizes one of the Hydrograph Methods listed in Section E.3.1 b). It is
applicable to design of complex minor drainage systems and all storage calculations and
major drainage systems and involves the integrated design of both the minor and major
systems.
E.2
STORMWATER MANAGEMENT
E.2.1 Major and Minor Systems
The stormwater management system shall consist of the following components:
Schedule C: Design Criteria
C60
Subdivision and Development Servicing Bylaw No. 2589, 2013
City of Pitt Meadows
#125335v12
a)
The minor system shall consist of pipes, gutters, catch basins, driveway
culverts, open channels, watercourses and stormwater management facilities
designed to convey flows of a 10 year return frequency;
b)
The major system shall consist of the route followed by storm runoff when the
capacity of the minor system is exceeded. The system shall consist of surface
flood paths, roadways, roadway culverts, watercourses, and stormwater
management facilities designed to carry flows of a 100 year return frequency;
and
c)
Where approved by the Director, a piped minor system may be enlarged or
supplemented to accommodate major flows.
E.2.2 Flow Control
The following criteria shall be used to limit flows from subdivision and development sites:
a)
Limit the post-development peak rate of runoff to the pre-development peak
rate of runoff for the 10-year design storm or to a higher rate of runoff
approved by the Director if the downstream drainage system and watercourses
have the capacity to carry a greater rate of runoff meeting the requirements of
Subsections E.2.2 b), c) and d).
b)
Downstream detrimental impacts should not be increased. Where peak flow
rates or volumes are increased and will cause detrimental impacts, provisions
for downstream improvements must be provided.
c)
Increases in peak storm flows and volumes to the major watercourses and
receiving waters shall be minimized. Any potential increase in storm flows and
volumes shall be analyzed for fish bearing watercourses and watercourses
presently close to full capacity.
d)
The number of stormwater control facilities shall be minimized, and the
Director may require the Developer to provide facilities to serve land other
than the land being subdivided or developed in accordance with Section 7.12 of
the Bylaw. Where detention is used, off-stream storage is to be provided
where possible rather than on-stream storage within a watercourse. Detention
facilities designed for flow control shall account for the effects of multiple
storms that do not allow the detention facility to empty completely between
storms. Where single-event models are used to determine the volume of
detention facilities designed for flow control, a factor of safety shall be used to
account for the effects of sequential storms. The factor of safety shall be 1.1
for development sites with a post-development impervious cover of 20%, and
shall increase linearly to a factor of safety of 1.5 for development sites with a
post-development impervious cover of 100%. Alternatively, continuous models
may be used to check for the effects of multiple storms.
Schedule C: Design Criteria
C61
Subdivision and Development Servicing Bylaw No. 2589, 2013
City of Pitt Meadows
#125335v12
e)
Groundwater infiltration shall be used where site-specific studies determine
that this practice is appropriate. Allowance shall be made for infiltration in the
hydraulic design if approved by the Director.
E.2.3 Water Quality Control
A water quality control plan may be required as part of the Stormwater Management Plan
at the discretion of the Director where there are reasonable grounds to anticipate
discharge of contaminants to the drainage system.
A Water Quality Inlet or Coalescing Plate Separator shall be required to treat the runoff
from all impervious surfaces at fuel transfer stations and other operations where there is a
risk of spills of petroleum hydrocarbons.
Where structural facilities for contaminant removal are required and single event runoff
models are used, facilities shall be designed to treat the runoff volume resulting from the
24-hour storm with a 6-month return frequency, unless specified otherwise by the
Director. The 6-month, 24-hour storm can be estimated as 70% of the 2-year, 24 hour
storm. Where continuous runoff modelling is used, contaminant removal facilities shall be
designed to treat 90% of the runoff volume in an average year.
E.3
DESIGN CRITERIA
E.3.1 Design Flows
Design flows shall be calculated using one or more of the following methods:
a)
Rational Formula
where Q = Peak Flow in m3/s
A = Drainage area in ha.
I = Rainfall intensity in mm/hr
R = Runoff coefficient (see Subsection E.3.5)
The rainfall intensity for the Rational Method should be determined using the appropriate
rainfall IDF curve with the duration equal to the Time of Concentration (TC) calculated as
indicated by Item E.3.4.
b)
Hydrograph Methods
Drainage designs using Hydrograph Methods require computer models capable of
modeling the hydrologic characteristics of the watershed and of generating flow
hydrographs from each sub-catchment for a critical storm or a series of storms and routing
the hydrographs through the drainage network pipes, channels and storage facilities.

The following programs are considered suitable for the applications indicated, but it should
be noted that the list of programs is not intended to be comprehensive or to exclude other
suitable programs:
- OTTHYMO: Suitable for preliminary design of rural and urban areas, especially where
backwater and surcharge effects are not significant. Also suitable for generating
design flows in cases where pipes are being designed using manual methods.
- HYDSYS: Suitable for design of systems with no surcharge or backwater effects.
- EPA SWMM RUNOFF and EXTRAN: Suitable for detailed evaluation of the operation
of drainage networks and storage facilities.
- QUALHYMO and SWMM TRANSPORT: Suitable for evaluating the performance of
storage facilities over long winter wet weather periods.
Other stormwater management models which have been calibrated with actual rainfall-
runoff measurements in adjacent municipalities and approved by the Director.
Whenever possible, modeling results shall be calibrated using observed rainfall and flow
data from the design watershed or a similar watershed. Sensitivity of the model
predictions to variations of key parameters shall be tested and the findings used to
develop realistic and conservative models.
Post-development hydrographs shall be generated at key points of the major drainage
systems for a 10-year and 100-year design storm with durations of 2, 6, 12 and 24 hours
for each development condition. A different range of storm durations may be appropriate,
subject to approval by the Director. This will identify the critical storm event to be used in
designing the system component. The storm durations that generate the critical peak flow
may be different from the durations that generate the critical storage volume. Systems
may require analysis for sequential storm events or modeling with a continuous rainfall
record (see Subsection E.2.2 d).
Detailed designs shall include maximum hydraulic grade lines (HGLs) of the minor and
major systems plotted on profiles of the minor system components and compared with
minimum building elevations (MBE) to demonstrate flood protection.
Modelling results are to be submitted to the Director in a report containing at least the
following information:
- Plans showing catchment and sub-catchment boundaries, slopes, soil conditions,
land uses and flow control facilities;
- Name and version of modeling program(s);
- Parameters and simulation assumptions;
- Design storm details; and
- Pre-development and post-development hydrographs.

connection.
E.3.20 Major System Design
a)
Major Flow Routing
All overland major flows shall have specifically designed flow routes located within
municipal rights-of-way. The major flow routing shall normally be along roads and in
natural water courses. Design criteria include:
- HGL is to be at least 300 mm below the MBE of adjacent buildings.
- Maximum flow depth on roadways: 300 mm.
- One lane, or a 3.5 m width at the crown of each roadway, is to be free from
flooding.
- Where a roadway is used as a major flow path, the road grades are to be
designed to accommodate and control the flow at intersections.
- Flooding is not permitted on private property.
- Overflow routes are required at all sags and low points in roadways and other
surface flow routes.
- Major flood routes are required at down-slope cul-de-sacs.
Flow capacity of road surfaces and swales can be calculated using the Manning
formula, which is presented elsewhere. The following values of the Manning
Roughness Coefficient "n" shall be used unless otherwise specified by the Director:
- 0.018 for paved roadway
- 0.03 for grassed boulevards and swales
- 0.04 to 0.10 for irregular or treed channels.
Design detail is to include consideration of flow velocities and the potential
requirement for erosion control measures.
In some cases (i.e. at sags in roads) it may be necessary to provide additional
designated municipal right-of-way to route the major flow to the nearest municipal

Stormwater Detention/Infiltration
GENERAL
The goal of the City in managing storm water is to provide sustainable hydrologic
systems that mimic natural systems, protect groundwater resources and minimize
downstream flooding and erosion. The City supports and encourages volume
reduction strategies and requires reduction of peak runoff rates through the use of
storm detention facilities.
Post Development storm water runoff from all Developments is required to be
controlled to prevent or mitigate flooding or environmental impacts to the
satisfaction of the Director. These controls may be in the form of:
- Detention storage in surface ponds or underground pipes, chambers or tanks;
and
- Infiltration systems designed to augment or reduce detention storage.
The City encourages innovative approaches to achieving control of post Development
runoff. Groundwater recharge in the form of rain gardens, vegetated swales and
infiltration galleries provide positive environment benefits. See Supplementary
Detail Drawings SS-3 to SS-6in Schedule D for specifications. Prior to proceeding with
designs, Consulting Engineers and Developers may consult with the Director to
explore innovative approaches they may wish to utilize on their projects. The
Director may require hydrological, geotechnical or other reports to consider
suitability of these approaches. The Director may require innovative approaches in
certain catchment or sub-catchment areas in support of other objectives.
STORAGE FACILITY REQUIREMENTS
Basic requirements for the temporary storage of stormwater include:
- a suitable location of defined area and volume; and
- a restricted outlet designed to maintain the discharge to the downstream
drainage system at a pre-determined rate of the pre-development run-off for a
ten year return period).
Schedule C: Design Criteria
C74
Subdivision and Development Servicing Bylaw No. 2589, 2013
City of Pitt Meadows
#125335v12
Outlet controls for storage facilities shall be designed using the standard orifice and
weir equations unless otherwise approved by the Director.
Orifice Equation:
Q = C A (2 g h)0.5
Where: Q = release rate (m3/s)
C = orifice coefficient (0.62 for sharp or square edge)
A = area of orifice (m2)
g = gravitational acceleration (9.81 m2/s)
h = net head on orifice (m)
Weir Equation:
Q = C L H1.5
Where: Q = release rate (m3/s)
C = weir coefficient
L = effective length of weir crest (m)
H = net head on weir crest (m)
Large storage facilities shall include provisions for discharges at rates greater than
the design release rate. Rapid drawdown of the water level may be necessary for
emergency purposes or to restore the available storage to accommodate subsequent
storm events.
Provisions to accommodate higher discharges shall include over sizing the fixed
openings and sewers connected to the control structure. Adjustable mechanisms
such as slide gates or removable orifice plates shall be used to regulate design
release rates unless otherwise approved by the Director. The extent of the over
sizing shall depend on the capacity of the downstream drainage system.
Design of inlet and outlet structures shall include consideration of energy dissipation
and erosion control. Safety grates are required over all inlet and outlet openings
larger than 500 mm diameter. Locks for access hatches are required.
STORAGE FACILTY TYPES
The following are acceptable stormwater runoff control alternatives. Design details
shall be in accordance with current technologies as outlined in Land Development
Guidelines for the Protection of Aquatic Habitat (Canada/B.C.), and Best
Management Practices Guide for Stormwater (Metro Vancouver), and related
documents or as otherwise approved by the Director.
Parking Lot Ponding: paved parking lots can be used as storage in many areas. The
allowable depth is a function of safety and convenience to the users. Depths not
Schedule C: Design Criteria
C75
Subdivision and Development Servicing Bylaw No. 2589, 2013
City of Pitt Meadows
#125335v12
exceeding 150 mm are generally acceptable. Flow control chambers housing a
relatively maintenance free flow control device complete with an emergency release
spillway shall be used in conjunction with this storage.
Dry Detention Basin: a detention basin will normally be designed as an off-stream
facility. The basin shall have minimum freeboard of 0.3 metres and a maximum
depth of 1.0 metres. The maximum side slope shall be 4 horizontal to 1 vertical.
Flow control chambers as detailed in above shall be required.
Underground Storage: underground facilities include tanks and oversized pipes, with
outlet controls. Cross sections and inlet and outlet locations shall be designed to
minimize maintenance requirements. Structural design to accommodate traffic and
maintenance access provisions are required.
Wet Detention Ponds: wet detention ponds are intended to provide detention
storage and maintain a permanent minimum water level. Minimum catchment area
of 20 ha to limit number of ponds. May accommodate recreational uses, overflow
elevations to be coordinated with MBEs.
Subsurface Disposal (Groundwater Recharge): subsurface disposal is intended to
allow all hard surface runoff to percolate back into the ground, this method along
with detention storage creates an effective way to achieve groundwater recharge.
Suitable for high permeability soils with low groundwater elevation. Suitable for low
detention volumes only, subsurface discharge of contaminated water is prohibited.
See Supplementary Detail Drawings SS-3 to SS-6 in Schedule D.
Development in the urban area of the City will implement this type of Stormwater
Runoff on site as ground conditions are favorable for this type of use. Geotechnical
investigation is required.
E.3.21 Perforated Drains
The Consulting Engineer shall determine the need for perforated drains behind the
proposed curbs or sidewalks to intercept water and show requirements on the design
drawings. Should the Consulting Engineer fail to identify the need for such drains, the
Director may order them to be installed during construction or during the maintenance
period should it become evident they are required. The costs associated with the
installation when ordered by the Director shall be borne by the Developer.
E.3.22 Ditches

SECTION 2: SPECIFICATIONS AND DETAIL DRAWINGS
2.1
Master Municipal Specifications and Standard Detail Drawings
The Specifications and Standard Detail Drawings of the latest edition and the
Design Guideline Manual of the Master Municipal Construction Documents
Association (MMCD) are incorporated into the City of Pitt Meadows Subdivision
and Development Servicing Bylaw.
MMCD is written to form part of a contract between an owner and a contractor,
and the MMCD Specifications, either directly or by reference to the General
Conditions, include references to the respective responsibilities of the Owner, the
Contractor and the Contract Administrator. The applicability of MMCD in
connection with this Bylaw is with respect to technical specifications and
construction details only, and does not involve the City in the contractual
relationship that the Owner has with the contractor(s) hired by the Owner or that
the Owner has with professional staff, consultants or other agents. Except as
specified elsewhere in this Bylaw, the City places full responsibility for design,
construction, installation, inspection, testing and record keeping of Works on the
Developer (the Owner) who is required to hire the Consulting Engineer (the
Contract Administrator) to undertake duties in accordance with the Bylaw, and
MMCD must be interpreted in this way.
MMCD Specifications, Standard Detail Drawings and Design Guidelines are
supplemented by this Section. In case of inconsistency, the Bylaw and Schedules
take precedence over MMCD.
This Section may be further supplemented by supplementary specifications and
drawings submitted in connection with a specific project and approved by the
