STORM WATER MANAGEMENT
Schedule 5 - 1
SCHEDULE 5 - STORM WATER MANAGEMENT
5.1. Storm Water Management General
5.1.1. SD-1 illustrates the major water courses within the City of Langford. Existing major
storm water control and/or treatment areas are shown. These areas are to be
preserved unless professional storm water management studies indicate otherwise.
The areas of the municipality where storm water infiltration and storm water detention
(storage) are required for development are also shown on SD-1.
The City Engineer may allow or require the use of storm water infiltration works in areas
designated on SD-1 for storm water detention, if the City Engineer is of the opinion that
soil conditions on the site in question are suitable for storm water infiltration, and may
allow or require the use of storm water detention works in areas designated on SD-1 for
storm water infiltration if the City Engineer is of the opinion that the soil conditions on
the site in question are not suitable for storm water infiltration. The City Engineer's
opinion shall be based on the contents of a storm water management plan for the site
prepared by the Engineer or Geoscientist of Record. (Bylaw 1513)
5.1.2. For all subdivisions and developments in all areas of the City of Langford, drainage
structures and features are required that will maintain the quality of site drainage
water, minimize erosion and retain sediments.
5.1.3. In the infiltration areas, the sandy and gravely soils have high infiltration potential and
surface drainage conveyance structures are limited, therefore the primary means of
storm water discharge will be by infiltration.
5.1.4. In the detention areas, storm water storage is required to control post development
storm water release rates. Storm water storage may also be used in other (non-
detention) areas as an alternative to upgrading downstream conveyance capacity if
analysis shows capacity to be inadequate for the design flows. Except where infiltration
is required and achievable, a municipal storm drain is required to serve each existing
and newly created lot.
5.1.5. Where parkland in excess of 0.25 ha has been dedicated to the City in conjunction with
the proposed subdivision or development, storm water detention and treatment
facilities may be located within the park, if in the opinion of the City Engineer the
treatment and detention area will not detract from the aesthetics of the park and will
not affect environmentally sensitive areas within the park and the usefulness to and
safety of the public.
5.1.6. If, in the opinion of the City Engineer, a community detention area for future
developments within a specific storm drainage catchment area would be preferable to
permanent on site storage facilities, then permanent storage and treatment areas on
site may not be required. The developer shall provide land dedication or cash in lieu of
this community detention area (by DCC or otherwise) and shall provide temporary
facilities and the infrastructure to direct storm water to those future detention areas in
STORM WATER MANAGEMENT
Schedule 5 - 2
accordance with this bylaw. Any lands required for the temporary facilities shall have a
right-of-way in favour of the City of Langford for storm drainage which may expire when
the community detention area is constructed.
5.1.7. A storm water management plan prepared by a Professional Engineer is required which
will show: (Bylaw No. 1669)
5.1.7.1
Scaled topographic site plan with existing cadastral and proposed development
layout.
5.1.7.2
Drainage catchment areas showing contributory area to the site, onsite
subcatchments, cumulative catchments and points of discharge.
5.1.7.3
Predevelopment and post development flows.
5.1.7.4
Internal drainage structures for conveyance, control and treatment.
5.1.7.5
Existing and proposed offsite works.
5.1.7.6
Erosion and sediment control works.
5.1.8. Within the areas where storm water detention is required, the Professional Engineer
shall certify that for all events up to the estimated 200 year runoff event there will be no
increase in water levels or rates of erosion at any point in the watershed as a result of
the development compared to original site conditions, before the removal of natural
vegetation.
5.2. Flood Plain Elevation Criteria
5.2.1. All structures intended for occupancy shall be designed with the underside of the floor
system situated 600 mm (1000 mm adjacent to Millstream Creek, between the Trans
Canada Highway and Treanor Ave.) above the 200 year peak flood elevation.
(Reference: City of Langford Official Community Plan, Map 16, 200 Year Flood Plain.)
Where adjacent flood elevations are not available the hydraulic profile shall be
extended through hydraulic analysis to the development site, except where the site is
clearly above the estimated flood elevations. All habitable structures shall also be
protected from flooding by grading drainage away from the structure and providing
overland flow routes through the site that are capable of safely conveying the 200 year
runoff event. These routes, if not on roadways, shall be maintained in perpetuity and
protected with rights of way in favour of the City.
5.3. Storm Drainage Systems Design Criteria
5.3.1. All minor systems, those designed and installed as part of the works and services for the
subdivision or development, shall be designed for a 10 year peak flow rate. The site
must allow for 200mm of ponding onsite to be directed to an overflow route either
piped or overland.
STORM WATER MANAGEMENT
Schedule 5 - 3
5.3.2. All minor systems associated with a commercial, industrial, multi family or institutional
development as described by City of Langford Zoning Bylaw shall be designed for the
1:25 year storm.
5.3.3. Previously undeveloped areas must create an overland route within the subdivision or
development for the 1:200 year rainfall event to allow for the failure of the drainage
system. This route must be physically protected and have a right-of-way in favour of the
City.
5.3.4. Where, in the opinion of the City Engineer, future development or subdivision shown in
the Official Community Plan for the City is probable for the lands adjacent to the
development or subdivision, storm sewers must be extended to the property boundary
and terminated with a cleanout or a manhole. A right-of-way in favour of the City must
be provided for this storm sewer on private property for access and maintenance.
5.3.5. Storm drainage conveyance or disposal systems are required in the road right of way
adjacent to the subdivision or development for all new and existing highways.
5.3.6. If a vertical seepage pit is installed for in ground storm water disposal for the 1:25 year
storm, the developer is not required to treat storm water with a oil separation device
prior to disposal unless the disposal system is constructed in conjunction with required
improvements for an auto repair or service facility, gas stations, or property zoned for
industrial uses. Vertical seepage pits shall be designed in accordance with SD-7.
5.4. Tributary Area Schematic
5.4.1. Runoff calculation for subdivisions and development of Small Sites may be by the
Rational Method. Analysis of upland and downstream catchments, up to a maximum of
10 ha, may also be calculated with the Rational Method. Calculations shall be submitted
in tabular form in accordance with SD-2 and certified by a Professional Engineer. For
larger catchments reference shall be made to the Storm water Management Plan for
pre-calculated values. The values shall be verified by the City prior to use by the
developer's engineer. Original calculations for Large Sites and areas exceeding 10 ha
shall be performed with a hydrograph method. Design parameters shall reflect BC west
coast conditions.
5.4.2. If in the opinion of the City Engineer conditions warrant, a tributary area plan shall
accompany the runoff calculation and include:
5.4.2.1
Scaled topographic site plan with existing cadastral and proposed development
layout.
5.4.2.2
Drainage catchment areas showing contributory areas to the site, on-site
subcatchments for each inlet, manhole and outlet.
5.4.2.3
Locations of other drainage structures including silt traps, oil grit separators,
and storage chambers.
STORM WATER MANAGEMENT
Schedule 5 - 4
5.4.2.4
Provision shall be made for servicing lands beyond (upstream) from the site by
providing a point of access on a right of way and adequate conveyance capacity
within the subdivision or development.
5.4.3
Rainfall intensity shall be taken from the intensity-duration-frequency (IDF) curves
provided in SD-3. The minimum initial time of concentration shall be 10 minutes. For
catchments which will remain undeveloped, the time of concentration shall be
calculated using good engineering judgement.
5.4.4
Where soils will be exposed by land clearing, measures shall be taken to minimize
potential erosion following the concepts illustrated in SD-4, including:
5.4.4.1
Scheduling works for the period April through October inclusive, to the extent
practical.
5.4.4.2
Clearing the minimum possible land area.
5.4.4.3
Clearing immediately before construction commences.
5.4.4.4
Restricting vehicle access and providing a surfaced working area.
5.4.4.5
Suspending construction activities during rainy periods and when soils are
saturated.
5.4.5
All disturbed surfaces shall be protected against the loss of soils through the use of silt
fencing as shown in SD-5 to be located wherever surface drainage will leave the site as
overland flow. Watercourses and ditches shall be protected by placing the silt fencing
along the bank of the channel. Bare areas subject to erosion shall be covered by hand
placed straw mulch.
5.4.6
Where disturbed catchment areas exceed 0.20 ha, a sediment basin as described in SD-
6, shall be constructed. This requirement may be waived in rocky areas or if
construction is completed in the April to October period and finished with a non-
erodible surface. Erosion and sediment control measures shall be constructed before
clearing and earthworks commence and remain in place until at least 80% of all building
construction and landscaping are complete. Sediment traps may be converted to
constructed wetlands at this time. Sediment traps shall be clear of sediments on
September 30 each year and re-excavated any time the available storage has been
reduced by one-third of the original volume.
5.4.7
Despite the requirements of this section it shall be the responsibility of the professional
engineer to specify appropriate measures and ensure that sediment-laden water and
any other deleterious substances do not leave the site or reach aquatic habitat areas.

can clearly demonstrate that the proposed system will treat storm water to the
same criteria as 5.13.3 and the proposed system is certified for performance by
the Professional Engineer for the specific site.
5.13.1.2
Infiltration systems shall incorporate appropriate pre-treatment systems (for
example an oil/grit separator) to protect contamination of the disposal area.
5.13.2 Where in-ground disposal is permitted, vertical seepage pits shall be provided and
installed in accordance with drawing SD-7. Seepage pits shall be protected by a catch
basin.
5.13.3 Drainage water quality improvements for all subdivisions and land developments shall
be achieved preferably with a constructed wetland as shown in SD-8 and to the
satisfaction of the City Engineer. With outlet control and sufficient live storage, the
wetland may also serve as a detention pond. The permanent water surface area (as
defined by the outlet culvert invert) shall be a minimum of 1% of the contributory
catchment area. The constructed wetland shall have a normal outlet capacity for the
peak 10 year design flow and an emergency overflow capacity for the 200 year peak
design flow that is routed in such a way that it does not flood downstream property or
subject it to erosion. Constructed wetlands should have maintenance vehicle access.
Where constructed wetlands are not used, proprietary systems with filtration media
may be approved if certified performance and a specification for the site are submitted
for approval by the City Engineer.
For Small Sites, or small catchments within Large Sites that cannot be directed to a
constructed wetland, the following alternative storm water treatment techniques may

Oil/Grit Separator Chamber with External High Flow Bypass
SD-12
Oil/Grit Separator - Type 1
SD-13
Oil/Grit Separator - Type 2
Permeable Pavement, in accordance with product specifications
These treatment facilities shall be designed on the basis of the post development peak
"6-month" event which is deemed to be 60% of the 2-year peak flow. Oil/grit separator
chambers may be proprietary or non-proprietary. Design criteria for non-proprietary
separators are included on the standard drawings. These concepts are expected to
remove approximately 90% of the sediment particles larger than 100 microns (0.1 mm).
5.13.4 For these subdivisions and developments, the designer is encouraged to use
combinations of engineered wetlands and ponds to conform to the water quality and
runoff rate requirements.
5.13.5 The following facilities may be used alone or in combination to achieve the desired
detention and treatment.
5.13.5.1
SD-14 shows a typical flow control manhole for use at stormwater detention
facilities where only the two year event is being controlled.
5.13.5.2
SD-15 shows a combined detention and oil/grit separator.
5.13.5.3
SD-16 illustrates a detention facility that will serve a 0.5 to 1.0 ha site that will
have no remaining native vegetation and is rocky with 15% slopes and must
provide detention for both the 2 year (watercourse protection) and 10 year
(storm drain capacity protection) events.
5.13.6 Stormwater storage volumes may be reduced if used in combination with an infiltration
system designed in accordance with good engineering practice. The reduction in the
storage requirement shall be proportional to the percentage of peak 2 year event post
development discharge that is infiltrated to ground. Stormwater storage may be
eliminated if the peak 2 year event post development discharge downstream from an
infiltration system does not exceed the release rate tabulated above.
5.14 Storm Water Management Guideline
5.14.1 An applicant for subdivision or building permit may be required to submit a storm water
management report by a professional engineer. The report must make reference to
Land Development Guidelines for the Protection of Aquatic Habitat and Stream
Stewardship: A Guide for Planners and Developers, available from BC Environment, and
must indicate how the development conforms to those guidelines. The engineer

report shall include a cost analysis for operation and maintenance. The report shall
provide detailed information on the following design criteria in accordance with
Sections 7.1.4 through 7.2.6 of this document.
7.1.4. Standby power and/or peakflow storage maybe required. The City Engineer shall
determine which options are more economically feasible based on location,
environmental concerns, storage capacity required and the availability of an external
emergency power source. In the case of standby power, an on-site emergency
generator is required. The selection of an appropriately sized generator for lift stations
will be based on design criteria in accordance with this bylaw. The generator must be
sized so that it will not be required to run at more than 80% of its total capacity while
having all pumps running simultaneously. (Bylaw No. 1817)

12.1.
General Procedures
12.1.1. Introduction
The City of Langford's Contract Drawing and Drafting Standards are to be applied to all drawing
submissions made to the City. These standards are necessary to ensure that the City receives
consistent drawings compatible with the City's corporate GIS system.
The City of Langford's Contract Drawing and Drafting Standards are based on current versions of
the industry standard software by Autodesk and ESRI. AutoCad Map 3D and ESRI ArcGIS are the
preferred drafting, design and GIS programs to be utilized by all contractors to the City. The
only file formats that the City of Langford will accept are AutoCad .dwg files or ESRI .shp file sets.
12.1.2. General
12.1.2.1.
All submitted digital drawings must reference the UTM Nad83 coordinate
system. All X-Ref drawings must be included with submissions, preferably
incorporated into the drawing itself.
All drawings submitted using Autodesk software must be designed in Model
Space and plotted using Layouts. Each drawing layout is to include and is
limited to one drawing sheet.
The drawing sheets will include single or multiple view ports depending on the
amount of design detail required to be shown. Each view port will include a
scale that best reflects the amount of detail required to be shown in the view
port. The User Coordinate System (UCS) can be rotated to allow better viewing
of the design works, but a north arrow must always be shown and the amount
of rotation must be recorded in the title block.
All drawings submitted will comply with the City of Langford's Detailed Mapping
Specifications available from the City's website or the City's GIS staff.
12.1.3. Drawing Review
12.1.3.1.
