values.)
Tc = Ti + Tt
Where:
Tc = time of concentration (minutes)
Ti = inlet or overland flow time (minutes)
Tt = travel time in sewers, Ditches, channels or watercourses (minutes)

velocity exceeds 3 m/s and super-critical flow occurs, provisions for
structural stability of the main and durability of the pipe shall be
addressed by the Consulting Engineer.
C.
Despite the above, where the slope of the proposed main exceeds
54
15%, scouring protection and anchor blocking shall be

SECTION NO. 5 - RAINWATER SOURCE CONTROLS, INFILTRATION & DETENTION
1.
GENERAL
The goal of the City in managing rainwater is to provide sustainable hydrologic systems
that mimic natural systems, protect groundwater resources and minimize downstream
flooding and erosion. The City shall require, unless exempt, volume reduction strategies
and reduction of peak runoff rates through the use of storm detention facilities.
(a)
Post Development rainwater runoff from all Developments is required to be
controlled to prevent or mitigate flooding or environmental impacts to the
satisfaction of the Engineer. These controls shall be in the form of:
(i)
Detention storage in surface ponds, underground chambers or tanks; and
(ii)
Infiltration systems designed to reduce runoff volume and augment or
reduce detention storage.
(b)
Systems are to be compliant with the Part 5 [Rainwater Source Control] of this
bylaw.
(c)
Stormwater outfall connections must be designed and constructed in compliance
with Provincial and Federal legislation, and subject to applicable terms and
conditions.
(d)
In areas where the City has completed Integrated Stormwater Management Plans
(ISMPs), the Consulting Engineer shall confirm with the Engineer if the design
criteria in the ISMP will govern over the criteria stated in this Bylaw.
(e)
All source controls, infiltration systems and/or detention facilities will require the
development of an Operations, Inspection and Maintenance Plan.
2.
RAINWATER SOURCE CONTROLS
(a)
General
(iv)
The City shall require, unless exempt by the Engineer, the implementation
of onsite rainwater source controls to assist in the management, control,
treatment and disposal of rainwater runoff.
A.
Source Controls are onsite features and facilities used to provide
water quality treatment, rate control, and volume reduction of
rainwater runoff.
B.
Water quality treatment source controls remove rainwater
pollutants by filtering runoff through vegetation and soil media.
They consist of on-site absorbent soil layers, bio-infiltration and bio
C.
-filtration facilities such as vegetated swales, rain gardens, swales
and basins or equivalent systems.
65
(v)
Source controls shall be located upstream of other rainwater or drainage
facilities, such as infiltration trenches and detention ponds, but can also be
managed within a private site.
(b)
Source Control Requirements
(i)
There are two goals through the use of source controls: volume reduction
(to retain rainwater through infiltration, evapotranspiration, or reuse) and
water quality (rainwater treatment).
The design storm that shall be used to size source controls is the 6-month,
24-hour return period storm, which results in the retention and/or treatment
of 90% of the average annual rainfall or 72% of the 2-year 24 event rainfall
depth, unless otherwise stated elsewhere in this Bylaw.
A.
The Rainwater volume reduction and water quality criteria listed
above shall be applicable to all Developments except Urban 3 -
Infill Single Detached/Duplex Residential Developments. All Urban
3 - Infill Single Detached/Duplex Developments shall apply a
minimum
300
mm
of
absorbent
soil
and
construct
infiltration/detention facilities for 1:100 year events; these objectives
will achieve both the volume reduction and water quality objectives
for these Developments.
B.
The list of areas that are exempt or have limited requirements from
the volume reduction and water quality targets are listed below
a. Lands that will remain undeveloped and are protected by a
Section 219 restrictive covenant from future development are
exempt from both the volume reduction and water quality
targets listed in this Bylaw.
b. Lands designated as the Historic Centre land use as a part of
the Historic Downtown Neighborhood Plan will be exempt from
the volume reduction target; however, the water quality target
will still apply.
(ii)
All the criteria listed above shall be confirmed with the Engineer prior to
design.
(iii)
Metro Vancouver's Stormwater Source Control Guidelines 2012, as
updated from time to time, may be referenced for design of source controls;
however, any guidelines stated within this Bylaw will govern.
(iv)
No persons shall carry out Development on any lands without first obtaining
written approval for a Rainwater Management Plan for the lands, installing
a system and granting the City a Section 219 (Land Title Act) Covenant
and Statutory Right of Way, providing assurances as to the continued
operation, performance, maintenance and monitoring of the System and
approval of a Spill Containment Plan for the emergency containment and
clean-up of spills of contaminants on the lands.
66
(v)
Prior to infiltration of any kind, all wells within the site shall be
decommissioned or converted to non-potable uses only except for
Agriculture developments without cross-connection.
3.

Absorbent Soils for Pervious Areas
(i)
Absorbent soil shall meet the specification in Section 4. 8 (e) of this Schedule.
(c)
Sizing Considerations for Water Quality Treatment Source Control
(i)
Water quality treatment is typically provided by vegetation, mulch and soil media
in a swale, rain garden or basin. The vegetated soil layer shall be sized to meet
the rainfall events as outlined in Section 5. 2 (b) (i) of this Schedule.
(ii)
The vegetation soil layer in the facility has a limited infiltration rate regardless of
the subsurface infiltration. A maximum facility infiltration rate of 30 mm/hr shall
be used.
(iii)
Raised inlets within the facility shall be provided to allow flows greater than the
treatment volume to be conveyed directly to an underlying rock trench with
perforated pipe for dispersion for infiltration or retention for Volume Reduction
providing that suitable ground conditions exist (as confirmed by a professional
hydrogeologist). During frozen ground conditions when infiltration through the
treatment facility is hindered or blocked, the inlets allow flows to be conveyed
underground to be infiltration or retained. Design requirements for inlets shall:
A.
include a sump and perforated pipe into underlying rock trench; and
B.
be raised 150 mm above the swale invert to promote ponding and
infiltration of small storm event runoff into the absorbent soil before
overtopping.
C.
Raised inlet to be below curb inlet height to prevent ponding on the road
surface, if applicable
(iv)
Runoff into the facility shall be distributed to avoid concentrating flows and locally
overwhelming the treatment capacity. This can be accomplished by utilizing
smaller, distributed or linear facilities rather than large, centralized facilities.
A.
Flat panel curbs adjacent to the swales shall be used instead of curb cuts
or piping flows into the swale.
B.
The maximum ratio of tributary pavement area to facility plan invert area
shall be 15:1 to avoid overwhelming the treatment capacity.
(v)
Refer to Figures 1, 2 and 3 of Schedule "K" attached to and forming part of this
bylaw.
(d)
Design Considerations for Water Quality Treatment Swales
(i)
The minimum depth of the swale shall be 300 mm.
(ii)
The minimum bottom width shall be 0.5 m.
(iii)
The maximum side slopes shall be 2H:1V.
(iv)
The maximum longitudinal slope shall be 2%.
69
(v)
The minimum absorbent soil depth in the swale shall be 500 mm.
(vi)
The absorbent soil specification is as listed in Section 4. 8 (e) (ii) of this Schedule.
(vii)
A perforated pipe underdrain is required to prevent the Growing Medium from
becoming saturated in areas of poorly draining soils.
(viii)
A 30 mm drop is required at the edge of paving or panel curb to finished ground
surface, to allow for positive drainage and compensate for buildup of sediment at
this edge.
(ix)
Swale plantings to be selected by Qualified Professional to achieve water quality
improvements. All vegetation will be non-aggressive, with a preference for native
plants. Deciduous trees should be selected to manage leaf drop from clogging
facility.
(x)
Refer to Figures 1, 2 and 3 of Schedule "K", attached to and forming part of this
Bylaw.
(e)
Design Considerations in Low Permeability Soil Area
(i)
In areas with low permeability soils where infiltration is not a viable option,
retention and bio-filtration facilities shall be used. Pollutant generating surfaces
will require bio-filtration facilities with vegetated soil layers underlain by retention
rock trenches.
A.
Bio-filtration treatment: Bio-filtration treatment removes rainwater
pollutants by percolation of flows through a vegetation and soil media.
They can be swales, rain gardens and basins. Pollutant removal
mechanisms include filtration, pollutant sorption to soil and uptake in
vegetative root zones. Depending on the site location, refer to Figure 1 or
2 of Schedule "K", attached to and forming part of this Bylaw.
B.
Retention facility: Retention facilities retain frequently occurring runoff on-
site and slowly exfiltrate over time and/or evapotranspire it. These
facilities are used to meet the Volume Reduction criterion in areas with
poorly-draining soils that drain to watercourses. Refer to Figures 3 and 4
of Schedule "K", attached to and forming part of this bylaw.
(ii)
Retention facilities can include a bio-filtration surface to provide water quality
treatment and underlying rock trench for volume reduction.
(iii)
The bio-filtration and retention facility calculated volume is to be retained in the
void spaces of the Growing Medium layer and underlying retention trench
assuming dry initial conditions.
(iv)
The rock trench shall be capable of draining from full to empty within
four (4) days after the end of a storm. To ensure this, the maximum depth of the
rock trench shall be the smaller of:
A.
2.0 m; or
70
B.
infiltration rate (mm/hr) x 24 hr/day x 4 days / (1,000 mm/m x porosity).
(v)
The infiltration rate of the trench shall be the saturated infiltration rate of the soil
at the design depth of the trench. Rates may be determined using standard
percolation tests but they shall be performed and monitored by qualified
geotechnical testing personnel. No safety factor is required for retention facilities
in poorly-draining soils because the surrounding drainage system is sized for
adequate flood conveyance and life and property is not at risk.
(vi)
The porosity of a rock trench shall be 0.35 minimum.
(vii)
The water holding capacity of the Growing Medium is calculated by multiplying
the swale area by 0.2 times (the difference between the soils field capacity and
wilting point) the swale Growing Medium depth. This volume can be subtracted
from the total catchment runoff volume to calculate the required retention trench
capacity.
(viii)
The retention trench capacity shall be calculated as the sum of the trench porosity
volume and the infiltration volume during the 24-hour storm.
(ix)
Trench porosity volume = trench bottom area x trench depth x porosity.
(x)
24-hour infiltration volume = trench bottom area x infiltration rate x 24 hours.

Refer to Figures 2, 3 and 4 of Schedule "K", attached to and forming part of this
Bylaw.
(f)
Design Considerations for Underlying Rock Trenches
(i)
This section applies to areas with low permeability soils draining to watercourses
and without regional infiltration facilities.
(ii)
The retention trench shall be wrapped with filter fabric to prevent fines from
migrating in from the sides of the trench and from the Growing Medium above.
71
(iii)
A perforated pipe underdrain is required at the top of the retention trench to
prevent the Growing Medium from becoming saturated in poorly draining soils
areas. A sump is required between the inlet and perforated pipe. See Figures 3
and 4 of Schedule "K", attached to and forming part of this Bylaw.
(iv)
Incorporate inlets from the swale into the storm sewer system raised 150 mm
above the swale invert to promote ponding and infiltration of runoff from small
storm events into the Growing Medium.
(v)
Inlets shall be sized for the minor system peak flow (10-year).
(vi)
Incorporate safe overflow path from the swale towards a major municipal
drainage system or failsafe conveyance route for flows in excess of the 10-year
return period.
(vii)
Refer to Figures 2 and 4 of Schedule "K", attached to and forming part of this
Bylaw.

INFILTRATION SYSTEMS
(a)
Design Considerations for Infiltration Systems
(i)
An infiltration system must be at least 1.2 metres above bedrock, clay or other
impervious soils.
(ii)
An infiltration system must be at least 1.2 metres above the maximum seasonal
water table.
(iii)
Minimum distances from an infiltration system to proposed or existing foundation
walls shall be 5.0 metres or as recommended by a professional geotechnical
engineer and setbacks from property lines shall be 1.2 metres.
(iv)
To mitigate potential negative effects on slope stability, groundwater infiltration
and recharge systems to be located within 200 m of the top of a steep slope (i.e.
greater than 20%) or ravine shall have design input provided by a geotechnical
Consulting Engineer.
(v)
The design of an infiltration system shall be based on the saturated infiltration
rate of the soil at the design depth of the trench. Rates may be determined using
standard percolation tests but they shall be performed and monitored by qualified
geotechnical testing personnel. A safety factor of three (3) shall be applied to the
results.
(vi)
Only the base area of the linear trench shall be considered as permeable.
(vii)
The maximum allowable storage time is 24 hours.
(viii)
A "Rainwater Analysis Sheet", ES-D-3 and ES-D-4 shall be submitted to the
Engineer. The Engineer may request calculations based on the information
supplied.
(ix)
Rainwater storage medium shall be resistant to chemicals found in urban runoff.
72
(b)
Design Considerations for Infiltration Trenches Underlying Treatment Swales
(i)
The infiltration trench media shall be wrapped with non-woven geotextile fabric
or equivalent to prevent fines from migrating in from the sides of the trench and
from the Growing Medium above.
Above-ground inlets in the treatment system shall connect to the subsurface
system for flows in excess of the rate that can soak into the Growing Medium
(at 30 mm/hr maximum) and for all flows during frozen ground surface
conditions. Refer to Figure 1 of Schedule "K" attached to and forming part of
this Schedule.
(ii)
The depth of the trench shall be governed by the groundwater table or bedrock
elevation and also by the allowable drain time.
(iii)
An infiltration system may not be used where bedrock or impervious ground or
maximum seasonal water table is within 1.2 m of the base of the infiltration
system or where a professional hydrogeologist recommends one not be used.
(iv)
The minimum distance from an infiltration system to property lines - except the
front property line - shall be the greater of either 3.0 m or City's Zoning Bylaw
setback requirement to minimize potential impacts to adjacent properties.
(v)
The minimum distance from an infiltration system to proposed or existing
foundation walls shall be 5.0 m or as recommended by a professional
geotechnical engineer.
(vi)
Avoid utility or other crossings of the infiltration system. Where utilities must cross
the infiltration system, construct impermeable trench dams to avoid conveying
infiltration water along the utility trench.
(vii)
The design of an infiltration system shall be based on the saturated infiltration
rate of the native soil at the design depth of the trench. Rates may be determined
using standard percolation tests performed and monitored by qualified
geotechnical testing personnel. The measured rate will be divided by a safety
factor of 3.0 for design calculations of 100-year infiltration facilities. The maximum
infiltration rate allowed in facility sizing calculations shall be 1,000 mm/hr.
(viii)
A groundwater table mounding calculation shall be performed by a qualified
hydrogeologist when sizing infiltration systems in areas where the maximum
seasonal water table is within 5.0 m of the ground surface.
(ix)
The base area only of the infiltration system shall be considered as permeable
for infiltration.
(x)
The base of the infiltration system shall be level to maximize the infiltration area.
(xi)
The maximum allowable storage time is 24 hours.
(xii)
A "Drainage Analysis Sheet", as contained in this bylaw, shall be submitted to the
Engineer. The City may provide calculations based on the information supplied.
(xiii)
Refer to Figure 1 of Schedule "K" attached to and forming part of this Bylaw.

RAINWATER TREATMENT
(a)
All Developments within the City must incorporate water quality treatment provisions into
design to meet the following targets:
(i)
Basic Control - Basic treatment focuses on removal of TSS along with associated
pollutants attached to those sediments, including low levels of petroleum
hydrocarbons (oil, grease and polycyclic aromatic hydrocarbons (PAHs)). Basic
control is applicable to all non-agricultural lands. The performance target is:
A.
80% removal of TSS for influent event mean concentration (EMC)1
greater than 100 mg/L but less than 200 mg/L. For influent EMCs less
than 100 mg/L, meet a goal of 20 mg/L effluent TSS. For sites generating
TSS greater than 200 mg/L, provide Enhanced Control (see below); and,
B.
Treatment should be applied to the water quality control volume as
described in Section 5., 2. (b) (i) of this Schedule; runoff above this
volume may bypass the treatment system(s). For facilities requiring the
use of a flow rate for design, use the rainfall distribution described in
Section 4. 5. (d) (v) of this Schedule. However, the system must be sized
to overflow the 1 in 100 year or have a system bypass for the 1 in 100
year storm.
(ii)
Oil Control - Oil removal is specifically required for sites where there is significant
likelihood that higher concentrations of petroleum will be released; in general,
this includes sites with significant presence or use of vehicles. The performance
target is:
A.
No on-going or recurring visible sheen in receiving watercourse(s), and
24-hour average Total Petroleum Hydrocarbon (TPH) concentration no
greater than 10 mg/L with a maximum discrete (grab sample)
concentration no greater than 15 mg/L; and,
B.
Treatment should be applied to all runoff up to and including the 1 in 10
year storm event, with no bypass allowed, and the catchment area to the
treatment system may be restricted to drives, roads, parking areas and
outdoor storage areas, as applicable. Depending on site specific uses,
treatment may be applied to runoff up to and including the 1% annual
exceedance frequency storm event, with no bypass allowed, at the
discretion of the Engineer.
(iii)
Enhanced Control - Enhanced control is intended to achieve a higher level of
dissolved metals removal and applies to sites experiencing intense vehicle
usage, for example, industrial sites, or other activities likely to yield higher levels
of pollutants. The performance target is:
A.
Exceed basic removal of TSS;
B.
Greater than 50% removal of the dissolved fractions of copper and zinc;
and,
1 EMC is the total mass pollutant in runoff from a storm event divided by the total volume of runoff from the same storm
event.
74
C.
Treatment should be applied to the water quality control volume as
described in Section 5. 2. (b) (i) of this Schedule; runoff above this volume
may bypass the treatment system(s). For facilities requiring the use of a
flow rate for design, use the rainfall distribution described in Section 4. 5.
(d) (v) of this Schedule.
(iv)
Table 5.2 demonstrates how these performance targets are to be applied for
various land uses. As well, the table lists rainwater best management practices
(BMPs) presumed to achieve the performance targets, if properly designed,
installed and maintained, and are accepted for use on properties within the City.

Street lighting generally refers to lighting of streets including Sidewalks, crosswalks,
intersections, rail crossings, roundabouts and Multi-use Pathways. The main purpose of
street lighting is to enhance visibility at night. For a pedestrian, this may mean better
visibility of the surrounds and the Sidewalk, while for the driver of a motor vehicle, it will
mean increased time to stop or to safely maneuver around an obstacle or a pedestrian.
(b)
Street lighting design shall comply with the most current edition of ANSI/IESNA RP-8,
MMCD Specifications and this Bylaw.
These standards are not intended to be a substitute for sound engineering knowledge
and experience in street lighting design and the Canadian Electrical Code. Street lighting
and traffic signal designs shall be prepared under the direction of a Consulting Engineer.
(c)
Where a Developer converts overhead utilities, street lighting shall be provided by the
Developer and the BC Hydro pole mounted lease streetlights shall be removed by BC
Hydro once notification has been received from the City.
(d)
Street lighting and traffic signal plans shall be signed and sealed by a professional
electrical engineer responsible for the design of the Street Lighting and Traffic Signal
Works and Services.

Note: Luminance Levels, Uniformities and Veiling Luminance are extracted from IESNA RP-
8-18 Table 11-1 Light Design Criteria for Streets and adapted to City Zones.
(a)
Lighting for Sidewalks and Walkways shall be as follows:
(i)
Maintained Average Horizontal Illuminance: 5 Lux or greater; and
(ii)
Maximum to Minimum Uniformity Ratio: 10:1 or less.
For major streets with high pedestrian activity levels, apply pedestrian lighting levels
defined in IESNA RP-8-18.
(b)
The illumination levels at all signalized intersections shall be as per IESNA RP-8-18
Table 12.1 Pavement Illuminance for Full Intersection Lighting. Pedestrian activity levels
shall always be medium or high. Where lighting is being considered for a non-signalized
intersection a lighting warrant (defined in the Transportation Association of Canada
Guide for the Design of Roadway Lighting Chapter 10.4) shall be undertaken to
determine the requirements and the amount of lighting (ie; full, partial or delineation
lighting). Where warrants are undertaken, they shall be submitted to the Engineer for
approval.
(c)
When undertaking lighting calculations on single-lane or two-lane Roadways, and the
maximum lane width is over the 4m, the width used in the calculation shall be 4m and
shall be applied in the travel portion of the Roadway starting at the road centre line. This
scenario will be most common for Residential or Industrial areas.
(d)
Where time limited parking lanes exist or are proposed, the lighting shall be calculated
as if the parking lanes are travel lanes. Full time on-street angled, or parallel parking
areas shall not be included in the luminance calculations. Bicycle Facilities shall be

to meet ultimate lighting level by showing future poles on the undeveloped side.
(f)
Curved Roadway sections (less than 600 m radius) or roads with steep and variable
grades (6% or greater) can be calculated using the horizontal illuminance method.
(i)
For determining what horizontal illuminance level should be used as an
equivalent to the recommended luminance level, a ratio of 1 cd/m2 equal to 15
lux can be used. For the calculations a 2 m grid should be placed across the
entire travel portion of the lanes.
(g)
On Roadways connecting Residential areas to Commercial areas, the spacing of
luminaires shall change gradually to suit the change in levels of illumination. In the case
where luminaire output or type changes, the spacing in the transition zone may not have
to change significantly. In any case, the spacing changes in the transition area shall not
be abrupt or irregular.

The requirements of BC Hydro, Canadian Electrical Code, Technical Safety BC - Electrical, and
WorkSafeBC, shall be followed with respect to clearances between streetlight poles, luminaires,
high voltage and other conductors.
Where BC Hydro clearances to poles and luminaires cannot be met, BC Hydro Lease
Lighting may be considered only when the Consulting Engineer can prove no viable City owned
lighting options exist. This shall include shorter than standard poles or locating poles on the
opposite side of the road than the overhead power lines. BC Hydro Lease lights shall meet the
required light levels defined unless approved by the City.
111
6.
LUMINAIRES
(a)
The Developer shall install LED luminaires for any new or replacement lighting
installations. The Consulting Engineer shall refer to the City's Approved Products List

Guidelines.
(b)
Detail drawings and specifications for traffic signal systems shall be prepared by a
Consulting Engineer experienced in traffic signal design
(c)
Before proceeding with traffic signal system designs or designs that may impact existing
traffic signal systems, the Consulting Engineer shall contact the Engineer to confirm the
scope of work and ensure the requirements of the project are fully understood. This is
particularly important for Developer derived work where the City is not directly
responsible for engaging the design firm.
G
(d)
The Consulting Engineer shall be knowledgeable in traffic signal design and specific City
requirements. The Consulting Engineer shall contact the Engineer prior to starting the
design to confirm materials and specifics as well as signal phasing.
(e)
The Engineer will provide list of specific products to be used. The Engineer will also
review signal phasing and signal timings with the Consulting Engineer.
City supplied materials at the Developers cost typically include:
(i)
Traffic controller and cabinet;
(ii)
Street name signs; and
(iii)
Padlocks.
2.
TRAFFIC SIGNALS AND CONTROL
(a)
Traffic signal details are standardized throughout British Columbia to avoid potential
confusion of the travelling public, both local and visiting. They are defined in the BC
Motor Vehicle Act. Items standardized include:
(i)
Vertical mounted signal heads;
(ii)
Left side secondary heads; and
(iii)
Order of signal indication.
116
(b)
The Standard Construction documents shall be used in conjunction with the BC Motor
Vehicle Act Regulations - Division (23) Traffic Control Devices and the BC Motor Vehicle
Act R.S.B.C. 1996, Chapter 318.
(c)
Refer to Part B, Traffic Signals, of the most current edition of the Manual of Uniform
Traffic Control Devices for Canada (MUTCD) for information on traffic signal
specifications, concepts and terminology.
3.
SIGNAL HEADS
(a)
General locations of signal heads are as follows:
(i)
Primary: Mounted over the Roadway which a vehicle is to enter
(ii)
Secondary: Mounted to the left of the Roadway which a vehicle is to enter
(iii)
Auxiliary: Mounted to the right of the primary head, or other location to enhance
visibility
(iv)
Pedestrian: Mounted on the far side of the intersection in line with the painted
crosswalk.
(b)
Signal visibility distance is defined as the distance in advance of the stop line from which
a signal must be continuously visible for approach speeds varying between 40 and 80
km/h. For speeds exceeding 80 km/h, the minimum visibility distance must equal or
exceed the minimum stopping sight distance. Visibility distance guidelines are shown in
Table 9.1.

(c)
Visibility of a signal head is influenced by three factors:
(i)
Vertical, horizontal and longitudinal position of the signal head;
(ii)
Height of driver's eye; and
(iii)
Windshield area
(d)
Lateral vision is excellent within 5° degrees of either side of the centreline of the eye
position (10° cone) and adequate within 20° (40° cone). Horizontal signal position should
therefore be as follows:
(i)
Primary heads within the 10° cone; and
(ii)
Secondary heads within the 40° cone.
(e)
Vertical vision is limited by the top of the windshield. Signal heads should be placed
within a 15° vertical sight line. Overhead signals should be located a minimum of 15 m
beyond the stop line.
(f)
Signal head sizes are to be as indicated in the Table 9.2.

(g)
Each approach to an intersection requires a minimum of one primary and one secondary
118
signal head. Requirements for additional signal heads are to be determined based on
visibility issues. Signal head placement are to be as indicated in the Table 9.3.

4.
SIGNAL POLES
(a)
Signal poles shall be Type L; however, type 4A poles, street lights poles and type S poles
can be used for mounting signals and type 3 poles with breakaway bases for advance
warning signs. The Consulting Engineer shall undertake pole capacity calculations using
MOTI's Pole Capacity Program to verify pole loading with pole supplier. The Consulting
Engineer is responsible for determining the suitability of these standard foundations for
the given soil conditions. Where soils are in question a geotechnical engineer should be
consulted to define the suitability of the foundations for the given soil conditions. Where
foundations are not suitable, custom foundations will be required.
(b)
The following shall be taken into consideration for signal pole locations:
(i)
Signal poles should be placed so the top of the concrete base is between 1.5m
and 2.5m from the face of curb or edge of pavement, preferably behind the
Sidewalk. 1m of concrete Sidewalk shall be placed around the pole base. A
pushbutton post shall be added if signal post is located more than 2.3m from curb
portion of front edge of wheelchair let down
(ii)
Pole arms should be oriented at 90° to the centreline of the road, except where
119
the intersection is skewed. When laying out a skewed intersection, ensure the
arms do not block the view of the signal heads for other approaches.
(iii)
Signal head tunnel visors shall be considered where signal heads are visible from
conflicting movements.
(iv)
Advance warning signals shall be considered where warranted.
(v)
Other key considerations for pole placement are:
A.
Ease of access to pushbutton for pedestrians, disabled and the visually
impaired;
B.
Maintaining wheelchair access around poles and from pushbuttons to
wheelchair ramps;
C.
Minimizing the number of poles required;
D.
Locating poles and signal heads outside vehicle turning radius to avoid
damage. This is particularly important in industrial areas;
E.
Underground and overhead utility conflicts; and
F.
For better visibility of vehicle and pedestrian heads.
5.
LEFT TURN PHASING
(a)
Left turns at signalized phasing options are as follows:
(i)
Permissive - Green ball display. A Permissive left turn has no signal indication
other than a green ball, which permits a left turn when opposing traffic is clear.
(ii)
Protected - Green arrow display. A Protected left turn presents a continuous
green arrow indication while all opposing traffic is held by a red ball. A Protected
Left Turn is always terminated with a yellow ball.
(iii)
Protected/Permissive
-
Yellow/Flashing
Green
arrow
display.
A
Protected/Permissive left turn presents a flashing green arrow followed by a
green ball. During the flashing phase (advanced movement), opposing through
traffic is held by a red ball. After the advance has timed out, left turn traffic is
presented with a green ball permitting the movement when conflicting traffic is
clear. The protected phase of this movement is always terminated with a non-
flashing yellow arrow indication.
(b)
Protected/Permissive left turns phasing shall be used however protected left turn
phasing can be considered for: dual left turn lanes; lack of sight distance to oncoming
vehicle; high speeds; and left turn phase in a lead-lag operation.
6.
SIGNAL PRE-EMPTION
(a)
Traffic signals near rail crossings require interconnection with the rail crossing controls
to ensure maximum driver safety.
(b)
The Consulting Engineer shall confirm with the Engineer if there is a requirement for
120
emergency vehicle pre-emption to override normal signal operation and provide
continuous green signals for emergency vehicles such as fire department equipment.
7.
AUDIBLE PEDESTRIAN SIGNALS
Audible pedestrian signals are required unless stated otherwise. The audible signal is
interconnected with the walk signal and produces a "cuckoo" or "peep" sound, depending
on the direction of crossing. The cuckoo sound is used for north-south crossings and
the peep is used for east-west crossings. Where the streets are not oriented north-south
and east-west, maintain consistency with adjacent signals.
8.
CONTROLLERS AND CABINETS
(a)
Controller cabinets are available in various sizes and styles depending on equipment
requirements. The Consulting Engineer shall confirm with the Engineer the approved
specifications for cabinet and base sizes. Cabinets should be located entirely within the
road right-of-way, including maintenance pad and door swing. Location should be
behind the Sidewalk, with access door on the side away from the Sidewalk and the
signals visible from the access.
(b)
Traffic signal controller cabinet shall typically be NEMA P-44DD complete with extension
base supplied by the City at the Developers cost.
9.
POWER SUPPLY AND DISTRIBUTION
(a)
General and Conduit
(i)
The Consulting Engineer shall confirm voltage and locations of suitable power
sources for the proposed signal system. Signals systems are typically serviced
from a 120/240 Volt single phase 3 wire system.
(ii)
Signal wiring and conduit shall include a minimum of 1 - 53 mm RPVC conduits
and 3 - 78 mm RPVC around to all four corners of the intersection (1 - 78 mm
for signal cables, 1 - 78 mm for loops and 1 - 53 mm for lighting and power
conductors and 1 - 78 mm for communications).
(iii)
Large concrete junction boxes shall be provided at each corner of the intersection
(one for communications and one for power/signal) except for the power/signal
conduits at the controller corner. At the corner nearest the controller a small
concrete vault shall be used for power / signal conduits that is in accordance with
BC MOTI Standard Specifications for Highway Construction.
(b)
Surge Suppression
(i)
The design shall define surge protection in the main service panel.
(c)
Uninterruptible Power Supplies (UPS's)
(i)
UPS's shall be used at all traffic signals. UPS's shall typically be piggy-back style
located on the traffic signal controller cabinet. The duration of operation flash
period during a power failure will define the UPS size and number of batteries
required. The use of UPS shall be confirmed with the Engineer.
121
(d)
Service Connection
(i)
The Consulting Engineer shall confirm service location with BC Hydro.
122

RECREATIONAL TRAILS
Trails in the City of Abbotsford are classified according to intended access and recreation uses
and type of construction materials. The intended access and recreation uses, along with site
characteristics, will dictate the type of trails to be developed including trail layout, width,
construction specification, landscaping and maintenance levels.
Trail types, layouts, design details and materials must be approved by the City of
Abbotsford prior to initiation of the trail development process.
Trails are to be developed for the use of the general public and the most common trail types are:
(a)
Multi-use Trail
Multi-Use Trails are 3 - 5 m wide with a smoothly paved surface to accommodate high
usage and wherever possible universal accessibility with a maximum grade of 5%. They
shall be designed and constructed in accordance with Standard Detail Drawing CS-TR-
1.
The primary focus is recreation for both pedestrian and cycling but Multi-Use Trails may
also be planned for community connectivity. They can accommodate maintenance
vehicle access. An example of this type of trail is the "Discovery Trail".
(b)
Main Trail
Main Trails are 3 - 5 m wide with a compacted granular surface for medium use and an
intermediate level of accessibility. They shall be designed and constructed in
accordance with Standard Detail Drawing CS-TR-2. Where the gradient exceeds 15%,
a stairway may be required at the discretion of the Engineer.
The primary focus is recreation for both pedestrian and cycling but Main Trails may also
be planned for community connectivity. They may accommodate maintenance vehicle
access at the discretion of the Engineer. Usage types and universal accessibility may
128
be reduced if constructed in areas with steep slopes. This type of trail can be planned as
the main trail where there is a hierarchy of trails, where there is a requirement for
vehicular maintenance access, or in place of a Multi-Use Trail where a hard surface is
not recommended due to environmental or safety concerns.
(c)
Secondary Trail
Secondary Trails are 1.5 - 3 m wide with a compacted granular surface for moderate
use and an intermediate level of accessibility. They shall be designed and constructed
in accordance with Standard Detail Drawing CS-TR-3. Where the gradient exceeds 25%
a stairway shall be constructed with materials and design that are approved by the
Engineer.
The primary focus of a Secondary Trail is recreation. Usage types and universal
accessibility may be reduced if constructed in areas with steep slopes. This type of trail
may lead off a Main Trail where there is a hierarchy of trails or may be the only type of
trail in a moderately used park or greenspace.
(d)
Nature Trail
Nature Trails are 1 - 2 m wide with a surface of native soil, wood mulch or compacted
granular material for lower levels of use and accessibility. They shall be designed and
constructed in accordance with Standard Detail Drawing CS-TR-4. Where the gradient
exceeds 30% a stairway shall be constructed with materials and design that are
approved by the Engineer.
The primary focus of a Nature Trail is for specific types of recreation, typically hiking or
mountain biking.
(e)
Planning, Design and Construction of All Trails:
(i)
Recreational trails often traverse natural parkland or open space areas. Designs
must accommodate all environmental requirements.
(ii)
Trees, other plantings and landscaping should be included along the trail corridor
to support policies in OCP section 3 'Make Walking, Biking + Transit Delightful',
and to improve the local climate and environment, hence making trails more
inviting for daily activity.
(iii)
Trail types and widths are at the discretion and approval of the Engineer.
(iv)
Associated works may be required such as, but not limited to: trail-head
amenities, parking, creek crossings, slope stabilization measures, boardwalks,
fencing, signage, viewpoints, drinking fountain, seating areas, stairs and access
controls.
(v)
Where trails are to be included in a development, they must be shown on all
associated plans, such as grading, servicing, landscape, tree preservation, and
storm water management plans.
(vi)
For narrow trails, maintenance and emergency access must be considered and
only small-sized specialized construction equipment will be allowed.
(vii)
Layout plans must be confirmed with City staff, with on-site confirmation prior to
129
any tree pruning or removals or other works occurring on site.
(viii)
Trail requirements and specialized trail construction details are available from the
PRC Office upon request on a case-by-case basis.
