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) 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 approved by the City Engineer 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. 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. Repealed. 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 ### Page 76 Source pages: 1–280 ## Page 76 STORM WATER MANAGEMENT Schedule 5 - 48 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 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. For all subdivisions and developments in the City of Langford, a stormwater management plan (SWMP) prepared by a Qualified Professional is required to be submitted to the City Engineer for approval prior to subdivision, foundation or building permit whichever is first. The SWMP should provide details on the proposed stormwater management systems and the assessment on the downstream drainage system. The submission must include: 5.1.7.1 General description of the proposed development. 5.1.7.2 Existing and proposed drainage catchment areas. 5.1.7.3 Method and parameters used for hydrological and hydraulic analysis. Percolation tests are to be performed in the winter months. 5.1.7.4 Peak predevelopment and post development flows for the 2-year and 10-year storm events. 5.1.7.5 Description and sizing of stormwater best management practice (BMP) features. 5.1.7.6 Locations, sizes, design flows / volumes and capacities of all proposed works. 5.1.7.7 Capacity assessment of infrastructure downstream of the development to the point of discharge to a natural watercourse for the 10-year (up to 900 mm in diameter) or 25-year (greater than 900 mm in diameter) return period events. This assessment shall consider the Community Plan and other available land-use information for the entire catchment area. 5.1.7.8 Erosion and sediment control works required during construction. ### Page 77 Source pages: 1–280 ## Page 77 STORM WATER MANAGEMENT Schedule 5 - 49 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. 5.2.2. Placement of fill is not permitted within a floodplain unless there is no net loss in the available flood storage volume up to the 200-year flood level. 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. Minor systems consisting of storm drains, gutters, catch basins, driveways and local road culverts and local roadside ditches, shall be designed to convey (without surcharge) flows up to the 10-year return period for pipes up to 900 mm in diameter and up to the 25-year return period for pipes larger than 900 mm in diameter. 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. 5.3.2.1 Major systems consisting of surface flood paths, roadways, trunk storm drains and culvert crossings under collector roads, arterial roads and provincial highways, watercourses, and bypass structures for onsite and offsite stormwater management, shall be designed up to the 200-year return period. Where the applicant demonstrates, to the satisfaction of the City Engineer, that overland conveyance is not practicable, such flows may be conveyed by a piped system subject to the approval of the City Engineer. 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. ### Page 78 Source pages: 1–280 ## Page 78 STORM WATER MANAGEMENT Schedule 5 - 50 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. 5.4.1.1 Stormwater management model (SWMM) based models shall be used for the hydrograph method, unless approved otherwise by the City Engineer. The SWMM model shall consider winter baseflows and antecedent groundwater and soil conditions. Land data shall be based on currently available post-develop land-use conditions as per the Community Plan. 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. 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 ### Page 79 Source pages: 1–280 ## Page 79 STORM WATER MANAGEMENT Schedule 5 - 51 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. Rainfall intensity shall be taken from the intensity- duration-frequency (IDF) curves provided in SD-3. Climate change shall be considered and incorporated into the design in accordance with EGBC guidelines. 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. ### Page 80 Source pages: 1–280 ## Page 80 STORM WATER MANAGEMENT Schedule 5 - 52 5.5 Pipe Main Parameters 5.5.1 Specifications Roughness coefficients Concrete 0.013, PVC 0.013 Minimum diameter 300 mm Minimum velocity 0.61 m/sec (flowing full or half full) Maximum velocity 6.1 m/sec Above this maximum velocity, special consideration must be given by the Professional Engineer to incorporate pipe materials and construction methods, including pipe anchorage, scour protection and energy dissipation to the satisfaction of the City Engineer.

The permanent water surface area (as defined by the outlet ### Page 88 Source pages: 1–280 ## Page 88 STORM WATER MANAGEMENT Schedule 5 - 60 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 be used: SD-9 Grass Swale SD-10 Filter Strip SD-11 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.

OBJECTIVES AND DESIGN CRITERIA 7.1. GENERAL: IT IS THE INTENT OF THIS DOCUMENT THAT ANY CONSTRUCTED LIFT STATION WILL BE A “TURN-KEY” PRODUCT. 7.1.1. The use of sewage lift stations is permitted providing all design options that would avoid lift stations have been considered. The City Engineer shall approve the proposed lift station location. Submersible sewage lift stations are preferred however, larger capacity sewage lift stations or lift stations with special design or siting requirements maybe considered. 7.1.2. Any lift station must be constructed fully functional, operational and with City-specified software installed. The SCADA (kiosk software) consultant shall be selected and retained by the City. 7.1.3. A preliminary design report shall be submitted by the Professional Engineer to ensure that the City’s concerns are addressed prior to commencement of detailed design. This 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) 7.2. LIFT STATION LAYOUT AND DESIGN CRITERIA 7.2.1. The structural, mechanical and electrical components of the lift station shall be designed to the OCP ultimate population build-out, in consultation with the Planning Department staff and in accordance with the City Sewer Master Plan for the designated catchment area(s). 7.2.2. Ideally, the lift station shall be located in an area where receiving sewers, water mains, and provisions for 3-phase power supply are concurrent and shall be located for convenience of operation and maintenance. 7.2.3.

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.
