Rainwater is a valuable resource that supports the protection, enhancement, maintenance of: - Aquatic and terrestrial habitat; - Surface water supply and groundwater resources; - Recreational opportunities; and - Community aesthetics and urban life. Storm drainage designs shall be prepared by the Consulting Engineer with qualified expertise in storm water management systems. Design criteria only specify the minimum requirements and the Consulting Engineer shall confirm with the City on the design requirements. Storm drainage designs shall conform to local government bylaws, regulations, guidelines, policies and federal and provincial statutes. Provision of a Design Brief for design related work may be requested, at the discretion of the Director of Engineering. The Consulting Engineer will need to confirm the following: a) Drainage catchment boundary b) Planned land uses within the drainage catchment c) Location of major pumped and gravity facilities d) Location of the future gravity conveyance systems e) New Westminster Citywide Integrated Stormwater Management Plan (ISMP) The presence of an existing municipal storm drainage system does not mean, nor imply that the existing system has adequate capacity to accommodate the proposed design flows either adjacent to the site or further downstream, nor does it indicate that the existing system pattern is acceptable to the City. Undersized or inadequate existing storm drainage facilities must be upgraded at the Developer's expense to accommodate the appropriate flows as specified herein. Alternative stormwater management proposals may be considered. A Stormwater Management Plan (SWMP) and Erosion and Sediment Control Plan (ESCP) are required for all proposed developments within the City. City of New Westminster STORM DRAINAGE SYSTEM Section 3 Design Criteria Page 3-2 Revised: January 12, 2026 Doc # 2828447 3.1.1 Stormwater Design Manuals, Guidelines and Plans The Engineering Design Criteria applies to the analysis, design and construction of storm drainage systems located in City rights-of-way, easements, lots and parks, and which will be eventually owned and operated by the City. In addition to the Engineering Design Criteria, the storm drainage design shall conform to the Citywide ISMP which provides design guidance and required water quality and infiltration targets for on-site storm drainage systems. 3.1.2 Citywide Integrated Stormwater Management Plan The Citywide Integrated Stormwater Management Plan (ISMP) provides information related to: - Approved goals and strategies for developments to minimize the effects of flooding, erosion on water quality and ecological health; and - Remedial and new capital works to be incorporated with developments. The ISMP is to be used in conjunction with the Official Community Plan (OCP) and relevant Neighbourhood Community Plans (NCP's) for mitigating the impacts of developments on the City storm drainage system. 3.1.3 Stormwater Management Plan A Stormwater Management Plan (SWMP) details the proposed storm drainage servicing for the development and the impact on the downstream system. Unless otherwise directed by the City, a SWMP must be submitted for City's approval. The submission shall include technical drawings and a report including: - Development characteristics; - Existing and proposed tributary catchment area and boundaries along with existing and ultimate land uses; - The development area within the drainage catchment including all features such as roads, ditches, watercourses with their environmental classification, existing and proposed drainage control structures, storm sewers, culverts, stormwater management facilities, and site grading; - Method and parameters used for hydrological/hydraulic analysis; - Tabulated pre and post development hydrologic and hydraulic calculations; - Major and minor systems flow routing; - Downstream conveyance capacity limitations; - Minor and major hydraulic grade lines of all proposed works; - Design calculations, details and supporting information for all stormwater management facilities to meet Citywide ISMP Volume 1 (Vision, Principles & Actions) and Volume II (BMP Tool Kit); City of New Westminster STORM DRAINAGE SYSTEM Section 3 Design Criteria Page 3-3 Revised: January 12, 2026 Doc # 2828447 - Proposed service connection locations, Minimum Building Elevations (MBE), and pre and post-development flows entering and leaving the subject site; - Groundwater management for the protection of municipal and private infrastructure and property; - External drainage issues and recommended options to address impacts; - Potential floodplain issues and recommended options to address impacts; and - Easements required. The SWMP shall demonstrate how the development and the proposed storm drainage system will be consistent with the Official Community Plan (OCP), Neighbourhood Community Plan (NCP) and the Citywide ISMP. A SWMP design report shall also be prepared if Runoff Hydrograph Method is used for the analysis (see Section 3.3.4). 3.1.4 Erosion and Sediment Control Plan Erosion and Sediment Control Plan (ESCP) shall be submitted to the City for approval. The plan shall include measures such as siltation basins, channels, sediment basins, cut-off ditches and swales, siltation fencing, soil covers, truck washes, etc. to manage erosion and sedimentation from the construction activities in compliance with City's Erosion and Sediment Control Bylaw 7754, 2016 and Sewerage and Drainage Regulation Bylaw 7746, 2015, as amended. 3.2 Design Objectives and Requirements 3.2.1 Servicing Objectives Design Frequencies The design frequency for storm drainage systems will be in accordance to the followings, unless otherwise directed by the Director of Engineering: City of New Westminster STORM DRAINAGE SYSTEM Section 3 Design Criteria Page 3-4 Revised: January 12, 2026 Doc # 2828447 Minor System Storm sewers, driveway culverts and local road ditches 1:10 Year (Mainland) 1:25 Year (Queensborough) Major System Watercourses, channels, culvert crossings, overland flood paths, major trunk storm sewers1 and outfalls 1:100 Year Flood Control Facilities Within the Fraser River Floodplain and major watercourse crossings under Provincial Highways 1:200 Year 3.2.2 Climate Change Impact Consideration The design of the storm drainage infrastructure shall incorporate climate change impacts based on the following principles: "Do nothing" Approach: for temporary infrastructure or assessment of existing infrastructure near the end of useful life (less than five to ten years of service life). The existing climate rainfall data and ocean boundary condition data shall be used to verify capacity. "Middle of the road" Approach: for new infrastructure (i.e. storm sewers, culverts, floodboxes and flow control facilities). Use a moderate climate change forecast for Year 2050 as discussed in Section 3.3.2. "Worse-case" Approach: for high-risk infrastructure (i.e. with catastrophic or high consequences of failure such as dikes and drainage pump stations). Use a moderate climate change forecast for Year 2100 as discussed in Section 3.3.2. 3.2.3 Combined Sewer System A significant area of the City is currently serviced by combined sewer systems. The City is committed to separate all combined sewer systems under the Regional Liquid Waste Management Plan. Separate sanitary and storm sewer systems shall be designed and installed for new subdivisions and rezoning applications along the entire site frontage. The development may be required to separate the combined sewer system immediate downstream from the site as determined by the Director of Engineering. 1 at the discretion of the Director of Engineering City of New Westminster STORM DRAINAGE SYSTEM Section 3 Design Criteria Page 3-5 Revised: January 12, 2026 Doc # 2828447 Flows in the combined sewers shall be calculated to account for both stormwater flows and sanitary flows as per the City's Sanitary and Stormwater design criteria. 3.2.4 Design Requirements & Procedures The design shall show in plan and profile the proposed storm sewer mains, service connections, existing underground services, overland flow details and ditch drainage patterns as applicable. The following considerations shall be incorporated into the design: a) A topographic field survey of the site with sufficient details to determine drainage patterns will be required including elevations of surrounding properties, existing drainage systems and the crown of the roadway. Proposed ground elevations for the final development should also be given. b) Provision must be made for house drains from each lot, either to storm sewer, open ditches in the road or lane, underground storm sewers elsewhere or natural watercourses. Onsite storm drainage works shall be consolidated into a single service connection into the City drainage system. c) Catch basin type shall be chosen according to Supplementary Specifications and Detail Drawings. Lead size shall be not less than that shown on Detail Drawings. Type of catch basin and lead size shall be marked on construction drawings. d) When establishing inverts in a manhole at the junction of two or more pipes, the crowns of pipes shall be coincident. In built up areas where there is not sufficient cover available at the ultimate upstream terminal, the design pipe profile may be invert to invert with the hydraulic grade line shown. 3.2.5 Site and Lot Grading Requirements Site grading around the building(s) shall be graded away from the foundation in accordance with BC Building Code and drain into a municipal drainage system, natural drainage path or roadway. Surface runoff across the parcel to adjacent lots is to be avoided. If cross-lot drainage is unavoidable, a swale shall be provided to divert runoff away from the lower lots. Lots lower than the adjacent roadways shall have road runoff directed away from buildings and driveways and into an appropriate municipal drainage system. a) Lot grades and swales shall have a minimum slope of 1% and a maximum slope of 6%. b) Where grade changes in excess of the above are required, the maximum slope should be 3:1. Where these occur between dwellings, the slope is to be located on the lower lot. City of New Westminster STORM DRAINAGE SYSTEM Section 3 Design Criteria Page 3-6 Revised: January 12, 2026 Doc # 2828447 c) Grade changes in excess of 1 m are to be accomplished by the use of a retaining wall. d) The maximum depth of rear yard swales shall be 0.3 m. e) The maximum depth of side yard swales shall be 0.2 m. The grade adjacent to the house shall follow the grade of the swale to maintain constant depth. f) At least one side yard of all dwelling units shall have a minimum (2% slope) level area of 0.6 m. g) The crossfall at the back of all units shall not exceed 2%. h) For all lots with detached and semi-detached dwellings having conventional rear yard setbacks and reverse frontage on arterial roads, the rear area shall be graded at 2% for at least 7.5 m of the total rear yard depth. i) The maximum flow allowed into a swale between two houses is that from 4 rear yards. j) The maximum flow allowed into a rear yard swale shall be that from 6 rear yards and in no case will the swale lengths be greater than 3 lot widths for single and semi-detach houses. For townhouse units, 8 rear yards and a maximum swale length of 4 lot widths will be permitted. k) The ponding depth over rear yard catch basins shall not exceed 0.3 m. l) Grade differences between housing units shall be minimized, especially where new developments abut existing developments. The vertical distance between the ground level at the rear wall of houses which back on to each other shall not be greater than that achieved by striking a 3% grade between the units. 3.2.6 Minimum Building Elevation (MBE) The MBE is defined as the elevation of the lowest floor slab in a building or the underside of the floor joists where the lowest floor is constructed over the crawl space. Crawl space is the space between a floor and the underlying ground having a maximum height of 1.2 m to the underside of the joists and not used for storage of goods or equipment damageable by floodwater. The MBE shall be established at least 0.6 m above the storm service connection invert at the property line or 0.3 m above the 1:100 year hydraulic grade line whichever is greater. For sites located within the Fraser River Floodplain, the MBE shall be established above the designated Flood Construction Level (FCL). The FCL is 0.6 m above the Fraser River Flood Design Level established by the Province of British Columbia. For sites adjacent to major watercourses other than the Fraser River, the FCL is 0.3 m above the 1:200 year return period hydraulic grade line of the subject watercourse. In addition, the MBE shall be 1.5 m above the natural boundary of any watercourse, lake, marsh or pond. City of New Westminster STORM DRAINAGE SYSTEM Section 3 Design Criteria Page 3-7 Revised: January 12, 2026 Doc # 2828447 The rationale used to establish the MBE for a site shall be presented in the SWMP or a separate report. 3.3 Runoff Analysis Storm drainage systems shall be designed to accommodate post-development flows using the Rational Method or the Runoff Hydrograph Method. For developments where the total tributary area is 10 hectares or less, the Rational Method will be used to compute the peak runoffs. For systems where the total tributary areas is greater than 10 hectares or where stormwater management systems require more than basic flow conveyance, the Runoff Hydrograph Method will be used to compute the peak flows and to design the runoff control facilities. All calculations pertinent to the design of the drainage system shall be signed and sealed by the Consulting Engineer and submitted to the Director of Engineering for approval. In areas serviced solely by combined sewers, pre and post development flows for both storm and sanitary contributions shall be determined. Where post-development flows exceed pre- development flows, onsite storage or equivalent best management practices will be required to limit peak discharge rates to pre-development levels. Existing conditions will be considered 'pre-development' for non-greenfield sites unless historical site design documentation is submitted. 3.3.1 Catchment Area The extent of the tributary areas of the storm drainage system under design shall be in accordance with the natural contours of the land, subject to any overall drainage plans established by the City. The Consulting Engineer is responsible to confirm the extent of the drainage area with the City prior to detailed design. Although minor changes in the catchment boundaries may be necessary for development, the post-development tributary area should not deviate from the total natural drainage area, unless otherwise approved by the Director of Engineering. The Consulting Engineer is responsible for obtaining true and accurate surface elevations and drainage system information under the existing and proposed future development conditions. The analysis must include all lands tributary to the drainage system, whether considered on-site or off-site to the Developer's parcels. 3.3.2 Rainfall Data Rainfall Intensity Frequency (IDF) curves for 5 minutes to 24-hour durations are based on the 2018 report: "Study of the Impacts of Climate Change on Precipitation and Stormwater Management" prepared by GHD for the Greater Vancouver Sewage and Drainage District. The City of New Westminster STORM DRAINAGE SYSTEM Section 3 Design Criteria Page 3-8 Revised: January 12, 2026 Doc # 2828447 recorded rainfall data in the regional rain stations up to 2016 were used to derive the updated IDF data. Climate Change Adaptation The City of New Westminster is located within Zone 4 of the Homogeneous Rainfall Zones developed for the entire Metro Vancouver area in the GHD study. The existing climate condition IDF curves are based on the dimensionless IDF curves for Zone 4 using index rain values selected for New Westminster for durations from 5 minutes to 24 hours. The moderate change future climate scenarios for time horizons of 2050 and 2100 were developed by scaling up the existing climate condition IDF curves with Delta Changes for Zone 4. Current 2016, future 2050 and future 2100 IDF curves for the City are provided on Figures 3.1, 3.2 and 3.3. Rainfall intensity taken from these curves can be used with the Rational Method to calculate design flows under the required time horizon specified in Section 3.2.2. Design storms shall be used for the Runoff Hydrograph Method computation. Tables 3.4 to 3.8 provide design storm hyetographs under current climatic condition (2016) for different return frequencies. To adjust for climate change impacts specified in Section 3.2.2, IDF curve values for future 2050 and 2100 conditions shall be used with the appropriate return period and duration to pro-rate the current (2016) design hyetographs. 3.3.3 Rational Method The Rational Method calculates the peak flow using the formula: Q = RAIN Where R = Runoff Coefficient A = Drainage Area (ha) I = Rainfall Intensity at the Time of Concentration (mm/hr) N = 0.00278 Q = Flow (m3/s) a) Runoff Coefficients The following runoff coefficients based on the highest and best land use in the City's Official Community Plan (OCP) shall be used to compute the design flow: City of New Westminster STORM DRAINAGE SYSTEM Section 3 Design Criteria Page 3-9 Revised: January 12, 2026 Doc # 2828447 Table 3.1 Runoff Coefficients Type of Area Percent Impervious Runoff Coefficient 10-Year Storm 25/100-Year Storm Wood Lands 5 0.10 0.30 Cultivated Lands 30 0.30 0.40 Park and Green Open Space 10 0.15 0.25 Low Density Residential (Single family, or Duplex, including secondary suites, up to a maximum of 3 dwelling units) 45 0.50 0.55 Medium Density Residential (Townhouse, Multiplex, e.g. up to 6-plex, Single Family with Laneway home) 65 0.60 0.65 High Density Residential (Apartment) / Institutional 80 0.75 0.80 Commercial / Industrial 90 0.80 0.85 Roofs / Pavement 100 0.95 0.95 The values in Table 3.1 are for general applications. The Consulting Engineer should verify the coefficient applicable for the area involved. The Director of Engineering shall have the final authority on the coefficient to be utilized. b) Rainfall Intensity The rainfall intensity used in the Rational Method should be determined using the appropriate rainfall Intensity-Duration-Frequency (IDF) curve with the duration equal to the Time of Concentration (Tc) calculated as indicated in the later section. c) Time of Concentration (Tc) Tc is the time required for water to flow from the most remote part of the catchment area under consideration to the design node. Tc can be calculated using the following formula: 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) Inlet or Overland Flow Time (Ti) City of New Westminster STORM DRAINAGE SYSTEM Section 3 Design Criteria Page 3-10 Revised: January 12, 2026 Doc # 2828447 Two methods can be used to estimate Ti as follows: i) This method is typically used for direct runoff from small urban development areas (< 2000 m²) with runoff coefficients greater than 0.4 under the assumption that BMP's are not applied. These values assume direct runoff. Land Use Type Ti (Min) Single Family Lot 10 Multi-Family Lot 8 Commercial/Industrial/ Institutional 5 ii) This method is used for relatively flat and larger areas and is calculated using the following formula (referred to as the Airport Method): Ti = 3.26(1.1 - C) L 0.5 S 0.33 Where Ti = Inlet time (minutes), minimum time = 15 minutes C = Runoff coefficient L = Travel distance (m), maximum length = 300m S = Slope of travel path (%) Travel Time (Tt) The travel time in sewers, ditches, channels or watercourses can be estimated using the following formula: Tt = Ct Ln 12 s 0.5 Where, Ct = Concentration coefficient = 0.5 for natural watercourses or ditches, storm sewer flow L = Length of watercourse or conduit flow (m), along the drainage path from the furthest point in the basin to the outlet. n = Roughness coefficient = 0.050 Natural channels = 0.030 Excavated ditches = 0.013 Concrete pipe = 0.011 PVC Pipe = 0.024 Corrugated Steel Pipe (CSP or CMP) s = Basin slope (m/m) City of New Westminster STORM DRAINAGE SYSTEM Section 3 Design Criteria Page 3-11 Revised: January 12, 2026 Doc # 2828447 d) Manning's Formula The hydraulic analysis of sewers and open channels shall be carried out assuming steady state flow conditions and using the Manning equation, with the pipe flowing full: Q = AR2/3S1/2 n Where, Q = Pipe Design flow (m³/s) A = Pipe cross section area (m²) R = Hydraulic radius (m) = diameter/4 for pipes S = Slope of energy grade line (m/m) n = Manning coefficient of roughness = 0.013 Concrete Pipe = 0.011 PVC Pipe = 0.024 Corrugated Steel Pipe (CSP or CMP) = 0.030 to 0.10 for open channels. e) Presentation of Rational Method Design Calculations The Consulting Engineer will be required to tabulate the Rational Method design calculations on the "Storm Sewer Design - Rational Method" table for submission along with the appropriate plans and other relevant information. Table 3.2 attached shows an example of the "Storm Sewer Design - Rational Method" table. Governing climate conditions for design calculations of the storm sewers shall be clearly noted in the design calculation sheet. 3.3.4 Runoff Hydrograph Method Hydrologic modelling programs using Runoff Hydrograph Method shall be used for the design of storm drainage systems serving areas greater than 10 hectares and for all erosion and detention retention/detention facilities. a) Selection of Modeling Program Prior to commencing any computer modelling, the Consulting Engineer shall obtain approval from the Director of Engineering on the selection of the proposed computer program. City uses SWMM based runoff simulation modelling programs. City of New Westminster STORM DRAINAGE SYSTEM Section 3 Design Criteria Page 3-12 Revised: January 12, 2026 Doc # 2828447 b) Modelling Parameters For design purposes, land use data shall be based on the best available post-development condition as per the Official Community Plan (OCP) and other pertinent land use information. Percent of imperviousness can be selected based on values suggested in Table 3.1 unless more accurate information from air photos or actual site designs are specifically available. Either the Horton or Green-Ampt methods may be used to estimate the infiltration characteristics based on the best available soil conditions information. The parameters must be reflective of the type of soils, ground cover and typical Antecedent Moisture Condition (AMC) prevalent during the winter season. c) Modelling Procedures Efforts shall be made to calibrate/validate the results using the observed rainfall/flow data. Sensitivity to input parameter values shall be tested to ensure that the model predictions are adequate for establishing a proper system design. Conservative parameters shall be selected if calibration data is not available. Design flows should be calculated at key intervals of the drainage system for all design storms (see Tables 3-4 to 3-8) with various design return periods, storm durations and climate change adjustments as prescribed in this document. This will identify the critical event to be used in designing the system. Note that the storm duration that generates the critical peak flow may be different from the duration that generates the critical storage volume. Systems with a number of interconnected ponds or with restricted outlet flow capacity may require analysis for sequential storm events or modelling with a continuous rainfall record. d) Presentation of Modeling Results A design report that documents the design rationale used to develop the hydrologic model and modelling results shall be submitted to the City along with a SWMP drawing. The design report shall include the followings: - Design criteria used for the hydrologic/hydraulic analysis; - Name and version of computer model; - Design storms; - Schematic diagram of model; - Drainage map showing the catchment and sub-catchment boundaries and areas, slopes, land uses, soil conditions, etc.; - Specific simulation assumptions and parameters; - Description of the proposed stormwater features; - Flow hydrographs under both pre- and post-development conditions at key locations; City of New Westminster STORM DRAINAGE SYSTEM Section 3 Design Criteria Page 3-13 Revised: January 12, 2026 Doc # 2828447 - Flow exceedance curves for the pre-development, post-development without detention and post-development with detention, if a detention facility is proposed and continuous modelling is performed; - Rationale and calculations for sizing onsite BMPs; - Operation and maintenance plans and performance monitoring plans for the proposed on- site stormwater management features. The SWMP drawing attached to the report shall include the following: - Catchment areas and boundaries and the proposed storm drainage system including storm sewer locations, sizes and slopes, and functional layout of the proposed detention facility, on-site BMPs and other hydraulic control structures. Minimum Building Elevations (MBEs) shall also be presented in the SWMP drawing. - A table summarizing design information and modelling results on the "Storm Sewer Design - Runoff Hydrograph Method" table. In addition, the following design details shall also be shown in the SWMP drawing or in the detailed design drawings for the storm drainage system: - Profiles showing pipe inverts and obverts, ground profiles, predicted Hydraulic Grade Lines (HGL's) under conditions governing the design and lowest MBEs throughout the storm drainage system. - Design details of the proposed detention facility, BMPs (e.g. rock pit, rain garden, bio- swale, etc.) and hydraulic control structures (e.g. catch basins, manholes, detention pond outlet structures, flow control/diversion structures, oil and grit separators, spillways, etc.). - Stage-discharge, stage-area and stage-volume curves of the detention facilities. - Tabulated peak inflows and outflows, design water levels, detention pond areas and storage volumes. 3.4 Storm Sewers and Appurtenances 3.4.1 Flow Velocity Maximum and minimum design velocities for pipes flowing full or half full: - Minimum 0.6 m/s; - Maximum 6.0 m/s. Where design velocities are supercritical or in excess of 3.0 m/s, special provisions shall be made to protect against sewer displacement. City of New Westminster STORM DRAINAGE SYSTEM Section 3 Design Criteria Page 3-14 Revised: January 12, 2026 Doc # 2828447 Where discharge velocities greater than 1.0 m/s enters a channel or sensitive receiving environment, evaluation of the downstream channel is required. Provisions for energy dissipation may be required to prevent scouring and control erosion. For all outfalls, a rigorous hydraulic analysis is to be completed to ensure that the exit velocities will not produce scour and damage. 3.4.2 Minimum Sewer Diameter and Grade The minimum diameter of storm sewers shall be 250 mm. The minimum grade shall be 0.25% for pipes less than 525 mm diameter and 0.10% for pipes equal or greater than 525mm diameter. In areas where the minimum grades cannot be achieved, the Consulting Engineer shall confirm with the Director of Engineering that the minimum velocity requirement is met. For new extensions, no reduction in pipe size will be made for pipes downstream irrespective of grade provided on the pipe unless specifically approved by the Director of Engineering. Sewers are to be designed with constant grade. Pipes with grades at 15% or greater shall have an anchoring system and scour protection as approved by the Director of Engineering. Due to the specific topography in Queensborough, minimum grade and velocity may not always be achievable. Site specific designs will be reviewed by the City on a case by case basis. A methodology must be identified to verify that the storm drainage system is designed and constructed with a positive gradient. 3.4.3 Storm Sewer Location Storm sewers and service connections shall be located within public road right-of-ways. Side or rear yard statutory right-of-ways or easements should be avoided if possible. The location of the storm sewer will be in accordance with the Supplementary Detail Drawings - "Typical Roadway Cross Section". If the location shown is impractical, the offset may be varied with the approval of the Director of Engineering but in all cases it shall be located under the road pavement and clear of curbs and gutters. At least 3.0 m horizontal clearance from water mains shall be maintained. Provincial regulatory separation requirements will govern where sewers are adjacent to or crossing existing or proposed water mains. Sewers must extend across the full width of each lot to the boundary of the development plan; thus allowing future extension and connection beyond the development where such extension is possible. City of New Westminster STORM DRAINAGE SYSTEM Section 3 Design Criteria Page 3-15 Revised: January 12, 2026 Doc # 2828447 Where not technically feasible to locate within a road right-of-way, a storm sewer may be located within an open lane or a statutory right-of-way (SROW) if authorized by the Director of Engineering and that: a) The open lane meets the minimum requirements of 6.0 m width; b) The open lane is capable of supporting maintenance vehicles and equipment access under all weather conditions; c) Within a statutory rights-of-way, the Owner must provide unimpeded maintenance vehicles and equipment access under all weather conditions; d) Within a statutory rights-of-way, the sewer shall be centred within the registered SROW with a minimum width of 3.0 m, unless the sewer depth exceeds 3.0 m or is combined with a sanitary sewer, in which case a greater SROW width shall be provided; e) There are no service connections or manholes within the SROW; and f) The sewer alignment in the lane or SROW is straight. All-weather vehicular access must be provided to all manholes, inlet structures, inspection chambers and flow control structures. The elevations of all existing underground utilities crossing the proposed storm sewer shall be confirmed in the field and shown on the profile and plan drawings. Where feasible, all new storm sewers shall interconnect at the high points to provide alternate routing of stormwater in case of blockage and for added subsurface storage capacity. 3.4.4 Sewer Depth Storm sewers shall be installed at a depth to: - Provide gravity service to all properties tributary to the sewer; - Prevent freezing; - Clear other underground utilities; and - Prevent damage from surface loading. The Consulting Engineer shall verify that the pipe material and bedding are suitable for the live and dead loads imposed on the pipe. In no case shall the cover be less than 0.9 m and greater than 6.0 m without the approval of the Director of Engineering. 3.4.5 Pipe Joints All storm sewers shall have water tight (gasket) joints unless otherwise approved by the Director of Engineering. City of New Westminster STORM DRAINAGE SYSTEM Section 3 Design Criteria Page 3-16 Revised: January 12, 2026 Doc # 2828447 3.4.6 Curvilinear Sewers Pipes are not to be laid on a curve unless approved by the Director of Engineering. 3.4.7 Manholes Manholes are required: - every change of grade or direction; - where sewers intersect; - when pipe sizes change; - at pipe intervals of 100 m; - at the end of each sewer line; - downstream of curved sewers (if a curvilinear sewer is approved by the City); and - wherever future extensions are anticipated. Generally, frames and covers should be located outside the vehicular and bicycle wheel path on the roadway. Where ditches discharge into a storm sewer system, the initial manhole shall be of a sump type. All other manholes shall be channelled and benched. A detail drawing shall be provided for manholes of special design. The inside diameter of manholes shall conform to the City approved edition of the MMCD and the City Supplementary Specifications and Detail Drawings. Manholes are required at service connection tie-ins to mains where the service connection size is greater than ½ the diameter of the sewer main or the service connection is 200mm diameter or greater. Drop manholes will only be used when a new incoming sewer cannot be steepened or where site conditions do not permit excavation to the base of an existing manhole. Outside drop shall be provided where the difference between the inlet and outlet inverts exceeds 600mm. The minimum manhole diameter for inside drop shall be: - 1200mm diameter manholes for mains 300mm or smaller; - 1500mm diameter manholes with an inside drop for mains larger then 300mm. Temporary cleanouts are required where an extension of the sewer, in the future, will provide a manhole at an appropriate spacing. Manholes shall be designed to incorporate a minimum pipe invert elevation difference of at least 30 mm in addition to the normal grade of the lateral sewer. For alignment deflections in excess City of New Westminster STORM DRAINAGE SYSTEM Section 3 Design Criteria Page 3-17 Revised: January 12, 2026 Doc # 2828447 of 45 degrees, a 60 mm drop shall be provided. The crown elevations of sewers entering a manhole shall not be lower than the crown elevation of the sewer leaving the manhole. 3.4.8 Groundwater Recharge For groundwater recharge systems in suitable soil conditions as identified by a qualified geotechnical engineer, additional site specific designed exfiltration systems shall be provided. Conversely, seepage collars or clay plugs shall be provided where groundwater may adversely affect deep sewers. 3.4.9 Perforated Pipes Perforated storm sewers may be used, subject to the approval of the Director of Engineering, to exfiltrate runoff back to the ground or to lower the groundwater table in areas where elevated groundwater levels are problematic for existing buildings and infrastructure. However, it shall not be used as a means to reduce constraints for new development. Perforated storm sewers used for groundwater recharge shall be flat, generally 1% or less. Perforated drains located adjacent to road shall be extended well below the road base. The trench for subsurface drains shall be filled with clear round drain rock in an envelope of approved filter material. The minimum size of the perforated pipe is 100 mm. 3.4.10 Catch Basins Catch basins shall be: - spaced to drain a maximum area of 500 m² on road grades up to 3% and 350 m² on steeper grades including sidewalks; - provided at regular intervals along a roadway, upstream of a curb return radius at intersections and at low points; - located to intercept the water flowing in the gutter in advance of a wheelchair ramp, curb letdown or pedestrian crossing; - avoided at low points within curb returns and where they interfere with crosswalks; Catch basins at low points and on steep grades shall include a side inlet for roads with a barrier curb. Double catch basins shall be used at low points and on steep grades for roads with roll- over curb. The Consulting Engineer must ensure that there is sufficient inlet capacity for design runoff to enter the underground pipe system. City of New Westminster STORM DRAINAGE SYSTEM Section 3 Design Criteria Page 3-18 Revised: January 12, 2026 Doc # 2828447 Generally, 600 mm diameter reinforced concrete catch basins shall be used for roadway drainage except when installation is restricted by depth. Special offset catch basins shall only be used where approved by the Director of Engineering. Grates shall have a "fish" symbol. Lawn basins shall be provided on boulevards and private properties where necessary to prevent ponding or flooding of sidewalks, boulevards, driveways, buildings and yards. Catch basin leads will have a minimum diameter of: - 200 mm for single basins - 250 mm for double basins. Double catch basins shall not be connected directly together but rather one basin will be wyed into the lead of the other. The maximum length of the lead is 30 m. The minimum grade for the lead is 2%. 3.4.11 Service Connections Each lot will have: a) A gravity connection to the frontage storm sewer; or b) A gravity connection to the storm sewer in an open lane, walkway or service corridor with an access road. A gravity service connection shall be made to the storm sewer where the habitable portion of a dwelling is above the major system hydraulic grade line (1:100 year return storm). A pumped service connection will be allowed when the habitable area of a dwelling is below the major system hydraulic grade line of the storm sewer. A backflow prevention device shall be installed at the gravity service connection line under such circumstance. In situations where the frontage storm sewer does not have sufficient depth to accommodate a gravity service connection and an existing combined sewer in an open lane can accommodate the design runoff, a service connection to the combined sewer may be considered if there is an established City plan to separate combined sewer in the open lane in the future, subject to the approval of the Director of Engineering. Every lot (existing or newly created) capable of being serviced, whether it is vacant or not, shall be provided with a separated service connection. The service connection shall be installed in accordance with the standard drawings. City of New Westminster STORM DRAINAGE SYSTEM Section 3 Design Criteria Page 3-19 Revised: January 12, 2026 Doc # 2828447 The minimum diameter of all service connections shall be 150 mm and have a slope not less than 2.0% from the property line to the main. Refer to the Supplementary Specifications and Detail Drawings for the location of storm sewer connections. No service connection shall be installed on sewers greater than 4.5 m depth unless otherwise approved by the Director of Engineering. Service connections will be located at the lowest corner of the property with the depth no less than 0.9 m. Where basements are proposed, the depths of the storm sewers and services shall be increased where feasible. The service connection invert shall be at least 0.6 m below the Minimum Building Elevation (MBE). Connections to new mains shall be made with a standard wye fitting. Connections to existing mains may use wye saddle or insertable tee. The service connection centreline must not be below the centreline of the sewer main. Inspection chambers are required on residential connections unless the service is less than 2.5 m long and connects to a manhole. Service connections exceeding 30 m in length shall be designed as storm sewers. Manholes are required on service connections larger than 250 mm diameter. 3.4.12 Surcharged Sewers Every effort should be made to avoid surcharge of existing or proposed sewers unless surcharge is unavoidable due to conflicts with existing utilities, structures or other implications. Surcharged sewers will have the 1:10 year and 1:25 year return storm hydraulic grade lines shown on the design drawings. In cases where the catch basins and storm sewers are designed to convey the 1:100 year return storm runoff, the 1:100 year hydraulic grade line shall also be shown. The 1:100 year hydraulic grade line shall be at least 0.3 below the lowest Minimum Building Elevation (MBE) of all of the serviced properties. 3.4.13 Culverts The minimum culvert diameter will be: a) 450mm for driveway crossing (Mainland) b) 600mm or equivalent for driveway crossing (Queensborough) c) 600mm for road crossings Culverts crossing roads will be designed to accommodate the major flow with either an inlet or outlet control. On collector and local roads, road overtopping is only allowed when the backwater profile does not negatively encumber properties. Where road overtopping is anticipated, appropriate scour protection shall be provided. All roads will be graded to provide the low point (sag) at the City of New Westminster STORM DRAINAGE SYSTEM Section 3 Design Criteria Page 3-20 Revised: January 12, 2026 Doc # 2828447 watercourse culvert crossing to provide a fail-safe major system outlet with limited ponding on the road right-of-way. Inlet and outlet structures are required for all major culverts. Design considerations are to include inlet control and outlet control conditions, energy dissipation and erosion control. The Consulting Engineer shall determine whether the culvert will operate under inlet or outlet control at design conditions. Aquatic habitat protection requirements must be considered for culverts in natural channels. Driveway culverts shall be installed or approved for installation by the City. All new driveway culverts shall be sized to ensure that there is no adverse impact on the adjacent properties under the major system runoff conditions. Culvert design calculations and assumptions shall be submitted for City and other regulatory agency approvals. 3.4.14 Flood Boxes New flood boxes through an existing dike may be required to facilitate drainage. New flood boxes shall have a minimum diameter of 600 mm or as directed by the Director of Engineering. Flood boxes will incorporate a flap gate on the river side of the dike, and be reverse graded to ensure proper seating of the flap gate during high tide conditions. Pressure treated timber support piles shall be installed on either side of the flood box and connected above and below the flood box with pressure treated 2x4 wood slats on the river side of the dike to anchor the flood box in place. At least 1/3 of the total height of the timber support piles will be buried below grade. Flood boxes shall be backfilled with structural clay, containing no organics, compacted to 95% Standard Proctor Density (SPD). A non-woven geotextile may also be required beneath the flood box, as designed by the Consulting Engineer. 3.4.15 Ditches and Swales Ditches are only permitted where approved by the Director of Engineering and shall be designed to convey minor system flows. Ditches shall be trapezoidal in shape having maximum side slopes of 1.5 H:1V and a minimum bottom width of 0.5 m, depending on the soil characteristics. The minimum ditch profile slope is 0.5%, except in lowland areas. The maximum velocity in an unlined ditch will be 1.0 m/s. Higher velocities may be permitted where soil conditions are suitable or where erosion protection has been provided. On steep slopes, grade control structures may be used to reduce velocities. City of New Westminster STORM DRAINAGE SYSTEM Section 3 Design Criteria Page 3-21 Revised: January 12, 2026 Doc # 2828447 The ditch right-of-way shall be sufficiently wide to provide a 3.6 m graded access road suitable for maintenance vehicles, in addition to the width required for the ditch, where the ditch is not adjacent to a municipal roadway. Swales shall be used in road allowances where there is no curb and gutter to direct flow towards catch basins or the storm sewer system. Swales will be used in conjunction with proper lot grading to convey runoff and minor flows, as well as direct major flows within City right-of- way. Ditches and swales are to be incorporated into road designs. 3.4.16 Inlet and Outlet Structures The Standard Detail Drawings shall be used as a guide for designing inlet and outlet structures for storm sewers and culverts. Structures that vary from the standard drawings shall include specific structural design with details shown on the drawings. Design of inlet and outlet structures is to include consideration of energy dissipation and erosion control. Outlets for culverts and storm sewers having discharge velocities greater than 1.0 m/s require evaluation of the downstream channel. Rip-rap or an approved energy dissipating structure may be required to control erosion. A trash screen/safety grillage is required at the entrance to every permanent storm sewer or culvert over 450 mm diameter or greater than 30 m in length (except large culverts over 1200 mm diameter). Grating with vertical bars, spaced no more than 150 mm apart, shall be installed and fixed in the form of a gate with adequate means for locking in a closed position. Provision for opening or removal of the gate for cleaning or replacing the bars is required. Gratings shall be designed to break away under extreme hydraulic loads in the case of blockage. Outfalls located in parks, ravines or on river banks should be aesthetically pleasing and safe. The appearance of these structures is important and cosmetic treatment or concealment shall be part of the design. Guard-rails or fences made of corrosion resistant material shall be installed along concrete headwalls and wing walls to provide protection against persons inadvertently falling over the wall. A storm sewer inlet from a ditch shall have a minimum diameter of 450 mm. City of New Westminster STORM DRAINAGE SYSTEM Section 3 Design Criteria Page 3-22 Revised: January 12, 2026 Doc # 2828447 3.4.17 Flow Control Structures For the design of flow control of storage facilities, riparian diversions and trunk sewer diversions, the orifice and weir equations may be used. Orifice Equation: Q = CA(2gh)0.5 Where, Q = Desired Release flow (m³/s) A = Area of Orifice (m²) g = Acceleration due to Gravity (m/s²) h = Net Head on the Orifice Plate (m) C = Coefficient of Discharge (0.62 for sharp or square edged orifices) The minimum orifice size shall be 100 mm in diameter. Where smaller orifices are required, special provisions are required to prevent blockage. These special provisions shall be clearly marked on the design drawings. Weir Equation: Q = CLH1.5 Where, Q = Desired Release flow (m³/s) C = Coefficient of Discharge (0.62 for sharp or square edged orifice) L = Effective Length of Weir Crest (m) H = Total Head on Crest (m) Flow control manholes shall be a minimum of 1200 mm diameter to provide for access and maintenance. The design of a flow control structure will include provision for safe conveyance of overflows. 3.4.18 Ditch Enclosure Roadside ditch enclosures will be replaced with an approved storm sewer system: a) To provide access to adjacent municipal or private property; b) To meet safety needs; or c) To meet community objectives if the ditch is classified as Class C or D under the City's Watercourse Classification System. Open ditches along local streets in Queensborough are required to be enclosed with an engineered storm drainage system unless otherwise specified by the Director of Engineering. City of New Westminster STORM DRAINAGE SYSTEM Section 3 Design Criteria Page 3-23 Revised: January 12, 2026 Doc # 2828447 For Class B and higher classification watercourses, input from qualified environmental professionals and authorization from regulatory agencies will be required. The design of the storm sewer system must provide compensation for lost storage volume resulting from the enclosure and ensure that there is no negative impact to upstream private or municipal property or infrastructure. Water surface profiles and hydraulic grade lines within the ditch in the vicinity of the proposed enclosure shall be shown on the design drawings. 3.4.19 Major Flow Routes Unless the storm sewer system is oversized to accommodate the major flow (i.e. 1:100 year return frequency storm), overland major flow routing is required. The major flow routing will normally be provided along roadways, culvert crossings and watercourses. In some cases the major flow may be carried alongside the road in swales or across side and rear of lots. These designated flow paths shall be protected by restrictive covenants or statutory rights-of-way and clearly identified in the Stormwater Management Plans. The quantity of flow to be conveyed by the surface flow path is the total overland flow minus the capacity of the piped system. The major flow routing shall be designed to ensure public safety and to minimize property damage under the major flow conditions. Urban roadways with curbs and gutters can be designed as wide shallow channels to convey overland major flow. The maximum depths of flow shall not exceed 140 mm above the gutter line. The design of intersections shall ensure that the surface flow can continue along the designated path crossing over lateral streets. Similar considerations are required if a change of direction is required at an intersection. Flooding will not permitted on private properties except in flow channels in municipal rights-of- way. Flow capacity of the overland flow routes can be calculated using the Manning formula presented in Section 3.3.3.

SANITARY SEWER SYSTEM 4.1 General Sanitary sewer design shall be prepared by the Consulting Engineer with qualified expertise in sanitary sewer systems. Design criteria only specify the minimum requirements and the Consulting Engineer shall confirm with the City on the design requirements. Sanitary designs shall conform to local government bylaws, regulations, guidelines, policies, regional Liquid Waste Management Plan and federal and provincial statutes. Provision of a Design Brief for design related work may be requested, at the discretion of the Director of Engineering. The Consulting Engineer will need to confirm the following: - Sewer service catchment boundary - Planned land uses within the sewer service catchment - Location of major pumped and gravity facilities - Location of the future gravity conveyance systems The presence of an existing municipal sanitary or combined sewer system does not mean, nor imply that the existing system has adequate capacity to accommodate the proposed design flows either adjacent to the site or further downstream, nor does it indicate that the existing system pattern is acceptable to the City. Undersized or inadequate existing sanitary or combined sewer facilities must be upgraded at the Developer's expense to accommodate the appropriate flows as specified herein. For all new developments, the discharge of storm water into the sanitary system or the combined sewer system is prohibited unless authorized by the Director of Engineering. A separated new storm system shall be provided for the development project. 4.2 Sewage Flow Generation 4.2.1 Residential Residential flow shall be based on 300 L/capita/day x population. The population is the ultimate saturation population from land use designations in accordance with the Official Community Plan (OCP) and related neighbourhood community plans for the subject catchment area. Refer to General Requirements Section: Design Population by Land Use. All design population assumptions must be approved by the Director of Engineering. City of New Westminster SANITARY Section 4 Design Criteria Page 4-2 Revised: January 12, 2026 Doc # 2828447 4.2.2 Non-residential Average Dry Weather Flows (ADWF) for non-residential areas shall be based on specific data related to the development or zoning. Table 4.1 Sewage Flows Land Use Average Dry Weather Flow General Commercial 34,000 litres/ha/day Office Towers 85,000 litres/ha/day Industrial Actual or expected land use with a minimum of 34,000 litres/ha/day Institutional - Hospitals 900 litres / bed/day - Nursing Homes 681 litres/bed/day - Schools 90 litres/student - Other According to Health Act Guidelines with a minimum of 23,200 L/ha/day Where sanitary flow from the development is expected to exceed calculated minimum flow from the above table, the actual development parameters shall govern. Separated Sewer Areas For development within existing areas, the design basis shall be based on the greater of: a) flows from the present development combined with anticipated flows for extension of the sewer to both developed and undeveloped lands; and b) flows from future development of the catchment area to full OCP density and land-use. Combined Sewer Areas For combined sewerage area where the proposed development will be discharging into the combined sewer system, the difference between the post-development and pre-development sewage flows must be estimated and the stormwater discharge be reduced by the same amount. Effectively, the increased sanitary flow from the development is offset by reducing the stormwater discharge which ultimately results in the same flow rate as the pre-development conditions entering the sewer system. City of New Westminster SANITARY Section 4 Design Criteria Page 4-3 Revised: January 12, 2026 Doc # 2828447 Until full separation of combined sewers is completed, the current combined sewer flows upstream and downstream of the subject development is to be used in the sanitary flow calculation, and any designated sanitary sewer systems may operate at a full flow condition (i.e. d/D =0.85) until full sewer separation within the catchment has occurred and all onsite/offsite drainage sources removed. 4.2.3 Design Flow Sanitary sewers shall be designed to convey the calculated peak sewage flows, including an allowance for inflow and infiltration. The steady-state design flow rate shall be calculated as follows: Qdesign = Peak Dry Weather Flow + Infiltration and Inflow Where: Peak Dry Weather Flow = QADWF x Peaking Factor + QPUMPED QADWF = Average Dry Weather Flow from all sources upstream that is conveyed by gravity QPUMPED = Peak Wet Weather Pumping Rate from all upstream pump stations. The total design sewage flow shall be based on the greater of: a) ultimate population densities and land use designations as outlined in the Official Community Plan for the entire catchment area, or b) planned developments for the entire catchment area. 4.2.4 Peaking Factor The Peaking Factor will be calculated using the Harmon Equation for the design residential population or equivalent population: Peaking Factor = 1000 4 14 1 Population + + 4.2.5 Infiltration - Mainland area inflow and infiltration allowance is 15,000 litres/ha/day City of New Westminster SANITARY Section 4 Design Criteria Page 4-4 Revised: January 12, 2026 Doc # 2828447 - Queensborough area inflow and infiltration allowance is 30,000 litres/ha/day. 4.3 Sewer System Capacity Review 4.3.1 System Capacity The Consulting Engineer shall discuss downstream system capacity requirements with the Director of Engineering. If required, the calculation of sufficient capacity of the existing system downstream of the proposed catchment area will be based on modelling results provided by the City at Developer's cost or as otherwise directed by the Director of Engineering. 4.3.2 Hydraulic Analysis The hydraulic analysis of gravity sewer pipes shall be conducted using the Manning equation under steady-state full flow condition: Flow Rate Where: Q = full pipe flow in cubic meters per second A = cross sectional area of pipe in square metres R = hydraulic radius in meters, D/4 (for circular pipes) D = inside diameter of pipe in metres S = slope of energy grade line in metres/metre of length n = Manning coefficient of roughness; 0.013 for all pipes Force Mains analysis shall be conducted using the Hazen Williams formula: Where: Q = Rate of flow in L/s D = Internal pipe diameter in mm S = Slope of hydraulic grade line in m/m C = Friction coefficient = 120 for all pipes 4.4 Sanitary Sewers and Appurtenances 4.4.1 Flow Velocity Design velocities for gravity sewers are: n S R A Q 2 1 3 2 ⋅ ⋅ = 278780 54 .0 63 .2 S D C Q ⋅ ⋅ = City of New Westminster SANITARY Section 4 Design Criteria Page 4-5 Revised: January 12, 2026 Doc # 2828447 - Minimum 0.6 m/s; - Maximum 6.0 m/s. Where design velocities are supercritical or in excess of 3.0 m/s, special provisions shall be made to protect against sewer displacement. 4.4.2 Minimum Sewer Diameter and Grade The minimum diameter of sanitary sewers is: - Gravity sewers: 200mm - Sewage force mains: 100mm Sanitary sewers will be designed as open channels with the depth of flow, under maximum design flow condition, not to exceed: - Up to 450mm diameter: 50% of the internal diameter (e.g. d/D=0.5) - 525 mm diameter or larger 70% of the internal diameter (e.g. d/D=0.7) For new extensions, no reduction in pipe size will be made for pipes downstream irrespective of grade provided on the pipe unless specifically approved by the Director of Engineering. Sewers are to be designed with constant grade. Pipes with grades at 15% or greater shall have an anchoring system and scour protection as approved by the Director of Engineering. The upstream terminal section of sewers may require steeper grade to ensure a self-cleansing velocity under partial flow conditions.

In general, if the flow from the hydrant does not exceed 60 L/s, the hydraulic head required at the water main upstream of the hydrant is 14m. If the flow exceeds 60 L/s, the hydraulic head must be greater to account for the head losses through the hydrant. The minimum hydraulic head immediately upstream of the water main required for a single hydrant delivering fire flows is as follows: Flow (L/s) Minimum Hydraulic Head at Water Main/Nearest Node Required (m) 45 14.0 60 14.0 90 15.8 120 22.6 150 31.4 For flow rates not detailed above, and for situations where multiple hydrants are required to deliver the fire flow, the minimum hydraulic head can be calculated as the greater of 14m and 7m plus the head loss through the hydrant. However, regardless of the fire flow delivered, the minimum hydraulic head at the water main or the nearest node must be 14m. Head loss through the hydrant(s) should be calculated as: HL = 1,083 x Q2 Where: HL is head loss (m) Q is fire flow (m3/s) City of New Westminster WATER DISTRIBUTION SYSTEM Section 5 Design Criteria Page 5-8 Revised: January 12, 2026 Doc # 2828447 5.5.4 Air Valves Combination air valves will be installed at the summits of all mains of 200mm diameter and larger except as follows: i.

The City has standardized the illuminance method for its lighting designs. The recommended minimum average maintained horizontal illuminance levels, uniformity ratios and veiling luminance ratios used by the City are listed in the ANSI/IES RP-8-00 - National Standard Practice for Roadway Lighting. Luminance and small target visibility (STV) methods shall be used where a specific circumstance warrants their use. Use of these alternate methods must meet the approval of the Director of Engineering. Tables in RP-8-00 to be referenced for roadway lighting are: Table 2: Illuminance Method - Recommended Values. Table 9: Recommended Illuminance for the Intersection of Continuously Lighted Urban Streets. Tables in RP-8-00 to be referenced for pedestrian walkway and bikeway lighting are: Table 5: Recommended Values for High Pedestrian Conflict Areas. Table 6: Recommended Values for Medium Pedestrian Conflict Areas. Table 7: Recommended Values for Low Pedestrian Conflict Areas. Table 8: Recommended Values for the Pedestrian Portion of Pedestrian Vehicular Underpasses and Exclusive Pedestrian Underpasses. Prior to starting a project, the Consultant shall verify the Road Classification (i.e. arterial, collector, local, etc.) and the Pedestrian Conflict Area Classification with the City. The road classifications, illuminance levels, ratios, road and pedestrian conflict areas proposed for each roadway and pedestrian walkway/bikeway shall be listed in a table format on the design drawings. The Consultant shall calculate all illuminance levels and ratios as noted under Section 6.8 Lighting Calculations.

Poles along the roadway shall be located at the outer edges behind curb and gutter or edge of pavement, or in special circumstances, in the median of the street. Where median lighting is being considered, the lighting levels on any sidewalks shall be met or additional supplemental sidewalk lighting maybe required. The exact offset of the pole (behind curb, edge of pavement or sidewalk) is typically defined on City's Standard Detail Drawings. Poles at intersections shall be located to accommodate intersections, property corners and pedestrian walkways. Spacing shall be governed by roadway width, road configuration and intersecting property lines. Generally, where possible, poles shall be located close to property lines and shall avoid being placed in front of residential windows. Poles shall be located at a minimum of 1.5m from the start/end of curb returns and at a minimum of 1.5m from the widest part of the driveway, including the flare. Pole spacing patterns include staggered, opposite, one side and median mount arrangements, depending on the roadway classification and road geometrics. The pole arrangements shall generally be as follows: 1) Roads 8.5m and narrower - One sided spacing 2) Roads over 8.5m wide - Staggered or opposite spacing 3) One sided spacing may be allowed when power line clearances cannot be met 4) Poles can be located in medians if a clearance of 0.5m from the pole to curb face can be maintained and posted speed is 60 km/h or less. A minimum of 2 consecutive poles should be required before considering poles in median islands 5) Maintain clearances of 3.0 m from overhead primary power lines to luminaires Where trees are proposed lights may have to be installed on davit arms which extend out over the roadway beyond the ultimate tree canopy. Additional pedestrian scale lighting may be required for the sidewalk. The proposed locations, spacing, pole height, arm length and frequency of the trees may also need to be adjusted in conjunction with the lighting pole spacing. The minimum City of New Westminster LIGHTING AND TRAFFIC SIGNALS Section 6 Design Criteria Page 6-4 Revised: January 12, 2026 Doc # 2828447 separation between poles and trees shall be 6.0m. The placement of poles shall have priority over the placement of trees. 6.6 Luminaires, Light Source and Smart City Luminaires The Consultant shall select the most effective IESNA luminaire distribution type (i.e.; Type 2, Type 3 etc.) and also meet the Roadway Lighting energy performance standard CAN/CSA-C653, Performance Standard for Roadway Lighting Luminaires, to suit the roadway geometrics. Cobra head luminaires shall be used for all roadway lighting applications with the exception of those defined by the Director of Engineering as Decorative Street Lighting areas (refer to Section 6.7). Cobra head roadway luminaires shall be Ministry of Transportation and Transit, or its successor in function's recognized product.

For development projects requiring pedestrian walkway/bikeway lighting, the cost for the supply and installation of the lighting system shall be borne by the Developer. The Consultant shall ensure the compliance of these design criteria and consult the Director of Engineering for specific fixture type, colour and model number information. 6.7 Decorative Street Lighting The City has designated areas in which Decorative Street Lighting and other electrical features such as pole and tree receptacles and irrigation systems are utilized to enhance the streetscape. City of New Westminster LIGHTING AND TRAFFIC SIGNALS Section 6 Design Criteria Page 6-5 Revised: January 12, 2026 Doc # 2828447 The City shall provide the Developer with generic details of the decorative lighting, the requirements for any other electrical features and a list of approved suppliers. Decorative poles may be suitable for roadways not exceeding 11 m width. Where decorative poles are required, the poles and anchor bolts shall meet all applicable codes and standards. The following details are required as part of the decorative lighting design: 1) Shop drawings of the street light poles proposed complete with pole design criteria 2) Signature and seal by the Professional Engineer, registered in the Province of B.C. 3) Detailed information and specifications of the luminaires proposed 4) Detailed information on pole accessories (decorative bases, banner arms, receptacles, etc.) 5) Drawings detailing assembled pole and luminaire units; and 6) Full size design drawings detailing the complete site installation. 6.8 Lighting Calculations Lighting design requires a computer lighting design software or Visual Roadway and lighting supplier photometric files from lighting suppliers in the IESNA format. Typically luminaire photometric files are based on a lamp which can vary from actual lamp used in the test, provided it similar. This referred to as "relative" photometry. LED photometric files must be "absolute" which means the photometric file must be for the exact luminaire being tested. The designer shall select luminaires with optical systems which efficiently light the interned area and properly illuminate the roadway and sidewalks as well as provide maximum spill light control beyond the sidewalk in order to reduce spill light and glare impacts on local residents. This shall be done by analyzing luminaire optical systems using the BUG method defined in Illuminating Engineering Society TM-15 Classification System for Outdoor Luminaires and Addendum A: Backlight, Uplight, and Glare (BUG) Ratings. The maximum nominal BUG rating of luminaires shall be B2-U1-G2 however lower BUG rating should be used where possible. The designer shall apply Light Loss Factor to the lighting design. For LED's the Light Loss Factor (LLF) is a combination of several factors representing deterioration of the lamp and luminaire over their life-spans which is applied to a lighting design. Several individual factors combine to form the overall LLF. The LLF then is incorporated into the design calculations. LLF = LLD x LDD x LATF Where: Lamp Lumen Depreciation (LLD) = 0.85. Luminaire Dirt Depreciation (LDD) = 0.90 Luminaire Ambient Temperature Factor (LATF) = 1.04 (+10° C). For LED's the range of LLF shall be 0.8. City of New Westminster LIGHTING AND TRAFFIC SIGNALS Section 6 Design Criteria Page 6-6 Revised: January 12, 2026 Doc # 2828447 Electrical design requirements include: 1) Allow for possibility of future expansion.

The provision of irrigation for the purpose of maintaining boulevard trees shall exclude boulevards in Queensborough. 7.9.2 Hardscaped Boulevards Hardscaped boulevards will be required in commercial and mixed-use areas, or where deemed necessary by the Director of Engineering. The concrete granular structure of hardscaped boulevards shall be equivalent to Sidewalk requirements and include drainage and irrigation. 7.10 Cycling Facilities The design of cycling facilities will be confirmed in consultation with the Director of Engineering and conform to the City's Active Transportation Network Plan and the latest editions of the BC Active Transportation Design Guide and TAC Geometric Design Guide. Intersection designs will require location-specific consideration but should follow principles of these and similar design guidance. 7.10.1 Facility Material & Width Unless otherwise approved by the Director of Engineering, bicycle facilities must be paved in asphalt. Bicycle facilities must be designed according to the following table. Table 7.8 - Bicycle facilities width Configuration Preferred width (m) Minimum width (m) Uni-directional bike lane 2.5* 1.8 Bi-directional bike lane 3.6* 2.5 Bi-directional multi-use pathway (shared with foot traffic) 4.0** 3.0 Painted bike lane (with buffer) 1.8* 1.5 Notes: * May be wider in areas with high cyclists volume (7500 bikes/day) ** May be wider for high volume facilities with a variety of different user types. Mode separations should be considered if there are more than 1,500 combined users on a facility. The width of the bicycle facility can be less than the minimum preferred width only over short distances due to constraints, with approval from the Director of Engineering. 7.10.2 Buffers City of New Westminster TRANSPORTATION Section 7 Design Criteria Page 7-12 Revised: January 12, 2026 Doc # 2828447 Where bicycle facilities are to be physically separated from other modes of travel, buffers must be incorporated according to the following table. Table 7.9 - Bicycle facilities buffers Design element Minimum Preferred width (m) Minimum width (m) Buffer separating bike lane from parked motor vehicles 1.0 0.8 Buffer separating bike lane from moving motor vehicle traffic 0.6 0.3 Buffer separating bike lane from Sidewalk 0.5 0.2 A buffer separating a bicycle lane from parked motor vehicles may be hardscaped or landscaped but should provide passable locations where people may easily move between parked motor vehicles and the Sidewalk. Adjacent to a designated loading zone, rollover curb may be used to improve accessibility. A buffer separating a bicycle lane from moving motor vehicle traffic must include a barrier curb on the road side. A buffer separating a bicycle lane from the Sidewalk must be detectable and accessible by people with disabilities. To achieve this, the buffer may be landscaped, grade separated with a detectable and accessible curb (e.g., sloped curb), or at the same grade with a cane-detectable longitudinal tactile surface indicator. 7.11 Transit Facilities The Consulting Engineer shall confirm the requirements for transit service and transit facilities for all roads designated as existing or future bus routes. The TAC Geometric Design Guide and TransLink's - Transit Infrastructure Design Guidelines shall be referenced. 7.12 Railway Grade Crossings As soon as planning is initiated or proposals are known by municipalities, notification and consultation should be initiated for: a) Development or redevelopment proposals within 300 metres of rail operations, or for proposals for rail-serviced industrial parks; and b) Infrastructure works, which may affect a rail facility, such as roads, utilities, etc. Municipalities, land Developers, property Owners, and railways all need to place a higher priority on information sharing and establishing better working relationships both informally and formally through consultation protocols and procedures. City of New Westminster TRANSPORTATION Section 7 Design Criteria Page 7-13 Revised: January 12, 2026 Doc # 2828447 Applicants are encouraged to provide clear direction and reference the City strategic Plans (e.g. through District Plans, Official Plans, Official Community Plans, Zoning By-laws, etc.) to ensure that land development respects and protects rail infrastructure and will not lead to future conflicts. This may include: - Undertaking a comprehensive evaluation of land uses in proximity to railway operations, with a view to minimizing potential conflicts due to proximity, including those related to safety, vibration, and noise. For example, residential development may not be appropriate in low-density areas where lot sizes hinder the possibility of incorporating standard mitigation measures. Additionally, schools or commercial uses located across a railway corridor from residential uses are likely to result in trespassing issues if there are no public crossings in the immediate vicinity. - Undertaking a comprehensive review of site access and railway crossings with a view to ensuring adequate site access setbacks from at-grade crossings (to prevent vehicular blockage of crossings), protecting at-grade road/ rail crossing sightlines, implementing crossing improvements, and discouraging new at-grade road crossings; - Planning and protecting for future infrastructure improvements (e.g. grade separations and rail corridor widening); and - Respecting safe transportation principles. For example, the assessment of new, at-grade rail crossings should consider safe community planning principles and whether other alternatives are possible, not just simply whether a crossing is technically feasible. Whenever roadworks cross an existing railway or railway right-of-way appropriate permits and approvals must be obtained. If these roadworks involve improvements to Arterial Roads, the MRN, Collector Roads, or Roadways with designated bicycle routes. Surface treatment will be at the discretion of the rail company at railway crossings. Consultation with all stakeholders, including the railways, at the planning process is important to building, understanding and informing nearby neighbors. In addition, initiating a conversation with railways can confirm the feasibility of a project and the practicality of proceeding. Key issues or concerns that may need to be addressed will be identified. Early contact between the applicant and the railway (preferably in the project's early design phase), is highly recommended, especially for sites in close proximity to railway corridors. This consultation is important in order to determine: a) The location of the site in relation to the rail corridor; City of New Westminster TRANSPORTATION Section 7 Design Criteria Page 7-14 Revised: January 12, 2026 Doc # 2828447 b) The nature of the proposed development; c) The frequency, types, and speeds of trains travelling within the corridor; d) The potential for expansion of train traffic within the corridor; e) Any issues the railway may have with the new development or with specific uses proposed for the new development; f) The capacity for the site to accommodate standard mitigation measures; g) Any suggestions for alternate mitigation measures that may be appropriate for the site; and h) The specifications to be applied to the project. Applicants should be aware of and implement, where feasible, Transport Canada's safety recommendations with respect to sightlines for at-grade crossings. The recommendations include a minimum 30-metre distance between the railway right-of-way and any vehicular ingress/egress. In addition, trees, utility poles, mitigation measures, etc. are not to block sightlines or views of the crossing warning signs or systems. At a minimum, all new residential developments in proximity to railway corridors must include a 1.83 meter high chain link fence along the entire mutual property line, to be constructed by the Owner entirely on private property. Other materials may also be considered, in consultation with the relevant railway and the municipality. Noise barriers and crash walls are generally acceptable substitutes for standard fencing, although additional standard fencing may be required in any location with direct exposure to the rail corridor in order to ensure there is a continuous barrier to trespassing. 7.13 Community Mailbox The applicant shall set the location of community mail boxes within the development and shall obtain agreement in writing from Canada Post regarding the location(s). The location of the community mail boxes shall not restrict access to any surface or underground infrastructure, and is subject to the City's acceptance. The Consultant shall provide the required SROW at the community box locations to enable Canada Post to install and maintain the box. 7.14 Traffic Control Devices Traffic control will be determined through the Comprehensive Transportation Review process. City of New Westminster TRANSPORTATION Section 7 Design Criteria Page 7-15 Revised: January 12, 2026 Doc # 2828447 7.14.1 Traffic Signals Where traffic signals are recommended, design shall be in accordance with Section 6 and be consistent with the Signalized Intersection Policy with a strong focus on designing for vulnerable road users. Controlled pedestrian crossings will be in accordance with the TAC Pedestrian Crossing Control Guide and consistent with the Signalized Intersection Policy. Bicycle traffic signal displays are required to be consistent with the TAC Manual of Uniform Traffic Control Devices for Canada. Detection of cyclists - preferably touchless (e.g., radar, camera, induction loop) - must be integrated with all pedestrian signals. 7.14.2 Traffic Signs and Pavement Markings If traffic signs are required for a proposed development, these will be designed by the Consultant and be in accordance with the most current edition of the Transportation Association of Canada (TAC) Manual of Uniform Traffic Control Devices for Canada and the most current edition of the BC Manual of Standard Traffic Signs and Pavement Markings and approved by the Director of Engineering. Fabrication of the signs shall be completed by City forces at the developers cost, installation shall be completed by the developers contractor. If pavement marking are required for proposed developments these will be designed by the Consulting Engineer. 7.15 Traffic Calming Appropriate traffic calming measures shall be considered and may be required by the Director of Engineering. Traffic calming design shall conform to the latest edition of the Transportation Association of Canada (TAC) / Canadian Institute of Transportation Engineers (CITE) "Guide to Neighborhood Traffic Calming". Alternative street designs may be considered as an option in lieu of traffic calming as approved by the Director of Engineering. 7.15.1 Speed Humps Speed humps shall be provided at the request of the Director of Engineering as per Supplementary Detail Drawings included in this bylaw. 7.16 Geometric Design Requirements 7.16.1 Design Speeds The following minimum design speeds must be provided for both vertical and horizontal alignment, unless otherwise approved by the Director of Engineering: City of New Westminster TRANSPORTATION Section 7 Design Criteria Page 7-16 Revised: January 12, 2026 Doc # 2828447 Table 7.10 - Road Classification & Design Speed Road Classification Design Speed Arterial Road/MRN 50 km/h Collector Road 50 km/h Local Road 30 km/h Lanes 20 km/h 7.16.2 Design Gradients A smooth grade line with gradual changes, consistent with the class of road and the character of the terrain, is preferable to an alignment with numerous breaks and short lengths of grade. The "roller-coaster" or "hidden dip" type of profile shall be avoided. At intersections of roads of unequal classification, the grade of the road centerline of higher designation will be maintained and the grade of the other road centerline will be altered to conform to the crown of the more major road. At intersections of roads of equal classification, the grade of the road centerline of each road will be constructed level for the width of the intersection. At any locations with grade transitions, the grade line shall ensure that the design vehicle underside or the front/ rear bumpers do not contact the pavement, with reference to the latest edition of the Transportation Association of Canada Geometric Design Guide for Canadian Roads or other appropriate design guidelines. 7.16.3 Cross Slopes and Super elevation Cross slopes for all Roadways shall not be less than 2% or not more than 4% in the direction indicated on the appropriate Road Cross Sections. The crown shall be in the center of the pavement. A standard "V-Shaped" cross section should be used for lane design. The need for any super elevation on any new roads shall be confirmed by the Consulting Engineer and approved by the Director of Engineering. 7.16.4 Drainage On Roadways with curbs, drainage is the essential consideration. Longitudinal gradients must be set to eliminate excessive accumulation of water on the pavements. Unless otherwise specified the following minimum gutter line gradients shall be used: i) Road - 0.36% City of New Westminster TRANSPORTATION Section 7 Design Criteria Page 7-17 Revised: January 12, 2026 Doc # 2828447 j) Cul-de-Sac - 0.50%. To provide drainage for flat roads that require false grading, the maximum gradient should not exceed 0.56% for roads and 1% for cul-de-sacs. Unless otherwise directed by the Director of Engineering, these gradients shall be used for all normal conditions of rainfall and outlet spacing. In special cases, a hydraulic analysis should be made to determine whether water will flow at an undesirable depth in the gutter. 7.16.5 Vertical Curves Vertical curves shall be designed in accordance with the latest edition of the TAC Geometric Design Guide for Canadian Roads, governed by the design speed of the road or laneway. 7.16.6 Horizontal Curves Horizontal curves shall also be designed in accordance with the latest version of the TAC Geometric Design Guide for Canadian Roads, governed by the design speed of the road or laneway. 7.17 Structural Design Requirements 7.17.1 Handrails, bollards and baffle gates Handrails, bollards and baffle gates shall also be designed in accordance with the latest edition of the Master Municipal Construction Documents (MMCD). 7.17.2 Retaining Walls Retaining structures may be required within street or lane rights-of-way or on private property to support roads, utilities, buildings, or to create a useable building envelope. The requirements for retaining structures shall be determined on the bases of a Site Grading Plan submitted for each development. Design drawings for retaining structures must be prepared and certified by the Consulting Engineer. Building permits are required for structures in excess of 1.2 meters in height and located on private property. Certification of inspection by the Consulting Engineer may be required by the Director of Engineering, as a condition of approval. City of New Westminster TRANSPORTATION Section 7 Design Criteria Page 7-18 Revised: January 12, 2026 Doc # 2828447 Handrails shall be installed on all retaining walls. Poly-coated wire mesh may be required to be attached to handrails where adjoining hazards are deemed significant by the Director of Engineering. Exposed concrete surfaces of an aesthetically pleasing appearance shall be specified for retaining walls. 7.17.3 Curb/gutter All roads shall be complete with concrete curbs and gutters in accordance with the City's approved edition of the Master Municipal Construction Documents (MMCD) and Supplementary Specifications and Detail Drawings. Traffic circle and lane curb and gutter requirements shall be approved by the Director of Engineering. 7.17.4 Medians Medians shall be sized in accordance with the Road Cross Sections and landscaped as outlined in Section 9. 7.17.5 Electrical and Telecommunications Utility Relocations It will be the responsibility of the Consulting Engineer to liaise with the City's Electrical Utility and other Telecom utilities at the preliminary design stage, to resolve the new locations and off- sets of the utilities and to meet the requirements of all parties. 7.17.6 Road Embankment Grading Road embankment shall be shaped to a slope of 1 vertical to 3 horizontal with sand fill and shall be finished with a seeded topsoil meeting the existing ground level or suitable alternative in accordance with Section 9. If the embankment slope is not achievable and it is adversely affecting drainage and driveways, retaining walls complete with top hand rail shall be used. The use of retaining walls should be avoided except in extreme cases. 7.18 Pavement Structures 7.18.1 General Pavement Design The basic road pavement structural design shall be adequate for an expected road life of 20 years under the expected traffic conditions for the class of road. This shall be determined by the City of New Westminster TRANSPORTATION Section 7 Design Criteria Page 7-19 Revised: January 12, 2026 Doc # 2828447 results of soils tests and analysis of the results of deflection testing performed on the surface of the road base gravel by a registered Professional Engineer. The minimum total flexible pavement structure thickness for any road shall be in accordance with standard drawings or greater if determined by the testing. The Director of Engineering may require the submission of a geotechnical report to confirm the structural adequacy of any existing or proposed street. 7.18.2 Existing Pavement Overlay of existing pavement shall be based on analysis of the results of Benkleman Beam tests, or other approved method, carried out on the existing road which is to be upgraded. The Benkleman Beam testing shall be carried out in accordance with current standards, published by the Transportation Association of Canada (TAC). The maximum Benkleman Beam deflection corrected for seasonal variation shall not be greater than: k) Industrial and Arterial Road /MRN - 1.00 mm l) Collector Road and Commercial streets - 1.25 mm m) All other road classifications - 1.50 mm The overlay thickness shall be determined by both the Benkleman Beam testing and by the shape of the cross-section of the existing pavement, so that an adequate crossfall on the existing pavement is obtained. The structure and/or grade of the existing pavement may indicate complete removal and reconstruction, which shall be carried out at the discretion of the Director of Engineering. All joints between existing and new asphalt surfaces shall be lap joints. The location and specifications of all joints shall be shown on the Consultant's drawings. 7.18.3 Asphalt-Concrete Pavement The following minimum pavement, gravel and sand thickness presented below shall be maintained.
