DRAINAGE 3.1 Run-Off Analysis 3.2 Minor System Design 3.3 Major System Design 3.4 Stormwater Storage 3.5 Erosion and Sedimentation Control DESIGN STANDARDS 3. Drainage 3.1 Run-Off Analysis This section describes the methods acceptable to the City of Revelstoke for use in the determination of the rate and amount of storm water run-off for the design of storm drainage conveyance and storage facilities. Hydrologic aspects of urban drainage (peak flows, volume and durations) directly affect the success of the design. Errors in analysis may result in under designing of facilities, over sizing them and incurring unnecessary expenditures, or both. In the interest of the public good, a conservative approach to all designs is warranted. The hydrologic criteria needed to calculate basin runoff are rainfall, soil types, vegetation and ground cover, extent of development and land slope and shape. It is expected that the design consultant will use criteria that is justifiable for the location of the development. Application of computer simulation models is recommended for all analysis and detailed design, however, the rational method may be used for pre-design analysis and for detailed design of minor systems with contributing areas less than 10 ha. Schedule 4 - Design Standards 3. Drainage Page 74 of 130 a) Rational Method The Rational Method may be used for pre-design system analysis and for detailed design of minor system components with contributing areas less than 10 ha. The Rational Method shall not be used for the design of major system components or storage facilities. The Rational Formula is expressed as: Q = CIA/360 where; Q = peak runoff, m 3 /s C = runoff coefficient A = area, hectares I = rainfall intensity, mm/hr Runoff Coefficient, (C). C values should be established based on the proposed land uses, proposed developments and hydro geological information. Calculations and justification for the determination of C values are to accompany development submissions. Developers and consultants are encouraged to look for ways to reduce the amount of Effective Impervious Area within their developments to reduce the amount of runoff generated and the costs associated with storm water infrastructure. "Default" C values, as shown on Table 1 can also be used. In a case of applying the Rational Method to a mixed land use in a drainage area, a weighted average C value should be used and can be calculated from the following formula: Cavg = S Ai Ci A where; Ai is the area with the same type of land use correlated to run-off coefficient Ri, and A is the sum total of all areas, Ai. Rainfall Intensity, (I). The value of the design rainfall intensity (I) for the Rational Formula is selected from the appropriate Intensity Duration Frequency (IDF) curve, with a duration chosen to coincide with the Time of Concentration. The Time of Concentration is the time required for run-off flow to become established and reach the design location from the furthest point within the contributing basin. Schedule 4 - Design Standards 3. Drainage Page 75 of 130 Time of concentration is the sum of two components, the "inlet time" and the "travel time". The inlet time is the overland flow time for run-off to enter the conveyance system. It varies with size of the catchment area and surface imperviousness. In developed urban areas where paved surfaces drain directly to catch basins, an inlet time of 10 minutes shall be utilized for assessment of 5 year and smaller design storms. Inlet times for higher intensity design storm events are as follows: Event Inlet Time (min.) 5 10 10 9 25 8 50 7 100 5 For inlet times in rural areas, the overland flow time must be calculated using appropriate formulas. The travel time is the length of time required for flow to travel within the conveyance system from the point of inflow to the location being analyzed. Rainfall: Standard Drawing COR-S21 shows the rainfall intensity-duration-frequency (IDF) curve for the City of Revelstoke, which was developed from the Atmospheric Environment Service recording station located at the Revelstoke International Airport. b) Computer Simulation of Run-off All minor storm drainage components draining areas larger than 10 ha. and all major storm drainage systems and storage facilities must be designed using computer- modeling techniques. The selection and the proper application of computer models is the responsibility of the Developer and the Consultant. It is necessary to utilize computer models which have the capability to generate hydrographs and which can route these hydrographs through a network of open channels, conduits and storage facilities showing volumes, hydraulic grade lines, the ability to simulate the minor and major system and their interrelation and the ability to simulate submerged and/or surcharged conditions. 3.2 Minor System Design Schedule 4 - Design Standards 3. Drainage Page 76 of 130 An urbanized area will have two separate and distinct drainage systems, whether these systems are planned and designed or not. The "minor system" includes street gutters, catch basin inlets and the network of underground pipes and facilities associated with the collection, conveyance and water quality treatment of minor, or frequently occurring rainfall events. a) Service Level The storm mains shall be designed for free-flow conditions for the 1:5 year storm (the rainfall that has a 20% probability of occurrence in any given year).

On local roads, the flow may spread to the crown except where curb over-topping will occur. c. On collector roads, the flow spread must leave one lane or a road surface equivalent free of water to ensure access for emergency vehicles (fire, ambulance). d. On arterial roads, the flow spread must leave one lane in each direction free of water. Flow across urban road intersections shall not be permitted for storms with a return frequency of 5 years or less. ii. Rural Cross-Sections Rural roads, gravel or paved, shall be constructed with swales or ditches that ensure adequate road sub-grade drainage (in compliance with Standard Road Design).

When a storm main is located within a statutory right-of-way and appurtenances, which require maintenance are located within the right- of-way, the landowner/developer must ensure that maintenance access is available. For large structures or structures requiring an enhanced maintenance level such as oil/sediment chambers, control structures and pond inlet/outlet chambers, an access route adequate to support the maintenance vehicles is to be provided. The surface of the route may be gravel, paves or asphalt depending on the location and the context of the site. v. Depth of Cover a. Provide 1.2 m in traveled areas and 1.0 m otherwise. However, these minimum's are to be used only when conflicts with other utilities will not occur and all upstream catchment areas are serviceable by gravity. b.

To ensure manhole construction will not cause a loss in hydraulic capacity, the design gradient shall be continuous through the manhole; otherwise, where the inlet is not at 180° to the outlet, a minimum drop of 30 mm shall be provided. f) Ground Water Recharge Systems i. To promote interception of pollutants and reduction in downstream impacts, ground water recharge systems must be utilized to the maximum extent possible as determined by a qualified professional experienced in this field. ii. Mains may be sized according to the required capacity taking 50% or the groundwater recharge capability into consideration. The groundwater recharge component must be calculated and justified by a qualified hydro geologist/engineer experienced in this field. Minimum sizes of mains must still be utilized. g) Storm Services i. Minimum diameter of storm services shall be 100 mm. ii. Minimum Grades for storm sewer services shall be 2%. iii. Storm services to properties shall not be permitted from storm drains located in rights-of-way unless a clean-out is provided and the nature of the development will permit access to the right-of-way for inspection, maintenance and repair, as necessary. Schedule 4 - Design Standards 3. Drainage Page 80 of 130 h) Roof Leaders Roof drainage leaders are to be connected to the storm service connection only where geotechnical requirements dictate the need. The evaluation of this requirement is to be included in the scope of the Hydro-geotechnical Study. Otherwise, roof leaders are to be directed to a splash pad for dispersal to the ground. Roof leaders shall not be directed onto driveways, which drain directly onto city right-of-way or areas draining directly onto neighboring properties. i) Water Quality Treatment i. Water quality treatment is required for frequently occurring events. All flows up to 50% of the 2year (1 hour duration) post-development flow must be routed through some form of water quality treatment facility utilizing "best management practices" to remove suspended solids and floatables. The facility can be an in-ground structure, which passes flow through or an aboveground facility such as a treatment wetland. Wetlands can be incorporated into larger storm water management facilities for the attenuation of large events. Allowable discharge criteria are identified in the City of Revelstoke Sewer Regulations Bylaw #1683. ii. Any form of water quality treatment must be designed to allow for future maintenance activities associated with the removal of the collected material and access to incoming and/or outgoing piping. j) Lot Grading/Swales and Driveways Lot grading shall be carried out in accordance with the BC Building Code and the following: i. Grade lots to drain to a municipal minor or major drainage system or a natural drainage path. Use 1% minimum grade. ii. Swales shall have a minimum slope of 1 percent. Swales shall be lined with turf on minimum 100mm topsoil or lined with a non-erodable hard surface. All such swales serving two or more parcels of property shall be designed to accommodate the anticipated flows and the right of way shall be sized accordingly (3.0 m minimum). iii. Avoid drainage across adjacent lots. If cross-lot drainage is unavoidable, provide a swale to divert runoff away from the lower lots. iv. Grade areas around buildings away from foundations. Schedule 4 - Design Standards 3. Drainage Page 81 of 130 v. To ensure flooding is avoided, carports or garages attached to residential buildings shall not be constructed with their floor level below the adjacent curb of City street or crown of pavement of City street, unless: a. the drainage of the driveway serving the carport or garage is connected by gravity to a City storm sewer meeting the connection criteria, or b. is above the 100 year flood line, or c. the runoff water from the driveway may flow past the carport/garage without accumulating and entering. Properties utilizing this method must have an Engineer seal the design. All other relevant criteria of this document must also be met. 3.3 Major System Design Storm runoff generated by less frequent, higher intensity rainstorms may exceed the capacity of the minor system. Runoff from these events will pond in depressions and follow whatever overflow route is available. This network of ponding and overland flows is called the "major system". If the major system is properly planned, it can alleviate the potential inconvenience and property damage caused by large rainfall events. a) Major System i. The major system includes all drainage infrastructures, which convey, detain, divert and intercept the 100-year design storm runoff. In general, all components of the major system must be designed to accommodate the flows generated by the upstream contributing area. ii. The following section describes the major system provisions and technical requirements for use in planning and design of the major drainage system. The depth of flooding permitted for the major event is as follows: a. For all classes of roads, the depth shall not exceed 0.3 m. b. One lane, or a 3.5 m width at the crown shall be free from flooding. c. Flooding is not permitted on private property iii. To meet the criteria for major storm runoff, sags or low points in roads or subdivisions must be designed with a safe overland outlet flow route. Schedule 4 - Design Standards 3. Drainage Page 82 of 130 b) Outfalls i. Ministry of Environment approval is required on all storm water outfalls to natural watercourses or water bodies. ii. Outfalls into lakes are to be constructed to have minimum bury according to the following: a. soft bottom, 0.6 metres to allow for seasonal sand erosion and deposition b. rock bottom, criteria to be confirmed by Coast Guard c. exposed pipes must be a minimum of 2.4 metres deep during lake "low water" to allow safe passage of deep keel vessels iii. Lake outfalls require approval from the Canadian Coast Guard. c) Control Structures i. Control structures, such as the one shown on Standard Drawing COR- S20 shall be used to provide consistent control for design storm flows of different return periods. These can be modified to include multi-stage inlets. For example, three orifices located vertically on a control structure are normally designed such that the lower, smaller orifice restricts frequent storms and the large upper orifices control less frequent larger storms. Safe overflow must still be available above the highest orifice. ii. Considerations shall be given for the design of smaller sediment trap basins at the points of discharge to the detention/retention facilities. Normally, basin inlets shall be designed to provide sediment containment. Build up of sediment shall not restrict inflows and suitable designs shall be provided to allow ease of sediment removals. d) Culvert and Bridge Capacity i. The following service levels are to be used for design: Design Flood Frequency Road Class Bridges, Culverts Arterial and Collector 1:200 year flood Local 1:100 year storm plus provision for overflow if on major channel Schedule 4 - Design Standards 3. Drainage Page 83 of 130 ii. Culverts over 30 m in length and/or 300 mm and larger in diameter shall be constructed with headwalls and end walls. The headwall shall be constructed with a free-swinging, weighted grating. To protect against entry, the City may require a locking mechanism, which limits the range of movement of the grating. e) Ground Recharge Systems Ground recharge systems are not normally considered for major flood routing. However, given the soil conditions in the Revelstoke area, geotechnical investigations may support the retention and ground infiltration of major events in some areas. Further details are provided in Section 4. f) Ditch and Swale Construction Velocity of flow in ditches and/or swales is not to exceed the limits given below for the various types of materials used as the conveyance surface. Maximum Permissible Lining Materials Velocity m/s Fine sand 0.45 Fine gravel 0.75 Stiff clay 1.00 For velocities higher than the above maximums, the Rip Rap Design Chart Standard Drawing COR-S22 is to be used. 3.4 Stormwater Storage This section identifies the general design parameters and requirements that must be considered by development proponents in the planning and design of storm water storage facilities. a) Peak Flow Control i. Control on peak flow rates and volumes in the City are necessary: a. To minimize impacts on watercourses and downstream developments from flow increases which will result from land development, and Schedule 4 - Design Standards 3. Drainage Page 84 of 130 b. To maintain or lessen flows in watercourses so that creek channels and existing structures, such as bridges and culverts, will continue to operate without being flooded or damaged. ii. In consideration of the above, the City has the following objectives and requirements: a. Impact and expenditures to existing downstream users shall not be increased. b. Increases in peak storm flows and volumes to the watercourses and receiving waters shall be limited. c. The number of storage facilities shall be minimized. (Permanent detention will not be permitted under private ownership, unless incorporated on-site within a private development). d. Permanent storage facilities are to be owned and maintained by the City. e. Where land developments occur in advance of permanent detention facilities, the City may consider temporary storage facilities on an individual basis. f. Maintenance charges and responsibility for temporary storage facilities will be borne by the developer. g. Storage facilities may be surface or underground. Rooftop or parking lot storage may be considered, where appropriate. h. Private property owners are to indemnify the City from liability arising out of private facilities. b) Basis For Detailed Design i. Level of Service a. Developments near lakes and/or watercourses are required to provide water quality treatment for flows up to 50% of the 2 year event. Flows generated from rainfall events greater than this can be discharged directly to a receiving body of water provided the required minor and Schedule 4 - Design Standards 3. Drainage Page 85 of 130 major systems exist and approval from the City of Revelstoke and the Ministry of Environment is obtained. b. Developments within other areas of the City of Revelstoke are required to provide water quality treatment for flows up to 50% of the 2 year event and to provide storage up to the 100 year (plus 10% volumetric safety factor) event with a maximum outlet rate based upon the 5 year pre-development rate generated by the catchment area. The release rate is to be based up on the post-development outlet hydrograph mirroring the pre-development runoff hydrograph up to the 5 year level. Release rates not based on this criteria may be allowed by the City of Revelstoke based on downstream conveyance system protection, stream protection, flood protection or water quality. c. An overflow shall be provided to route any excess water to the designated one hundred year flood route. Such an overflow can be in the form of a spillway or may be incorporated in the flow control structure through over sizing of downstream pipes, provision of overflow pipes or such other arrangement as the designer may devise. ii. Geotechnical Considerations a. Special geotechnical investigations to address issues related to the design of all storm water management lakes and dry ponds are to be undertaken as part of the planning and design studies, and are a prerequisite to the final design of such facilities. b. Wherever possible, the storm water storage facility shall be excavated in natural, stable ground. Should topography dictate that a berm be constructed along one or more sides of the basin, the berm shall be designed by a qualified professional engineer registered to practice in the Province of British Columbia and with relevant training and experience. iii. Staged Construction - Standards for Interim Facilities When storm water management storage facilities are to be implemented in stages, the standards applicable to the design and construction of the interim facilities are to be generally in accordance with the standards set out herein for permanent facilities of that type. (e.g. Where an interim dry pond facility is proposed as a preliminary stage in the implementation of a storm water Schedule 4 - Design Standards 3. Drainage Page 86 of 130 lake, it shall be designed and constructed in accordance with the criteria and standards applicable to a permanent dry pond.) c) Design Requirements Common To Stormwater Management Storage Facilities i. Land Dedication a. Generally, the area of land covered by water when the basin is at the 5- year water level will be dedicated to the City. This dedication will also apply to all accesses to inlets/outlets, any structures and maintenance access routes to the facility. b. Land that is adjacent to a basin which is subject to flooding as per the design standard established, but which is part of a privately owned developed parcel, will be required to carry rights-of-way, to allow for encroachment of water onto the affected land. The right-of-way documents shall be prepared by the development proponent, naming the City as grantee. c. A restrictive covenant will be placed on lots abutting the facility to control lot development so as not to compromise design requirements at the HWL. This is to ensure an adequate freeboard is maintained. ii. Maintenance Access Requirements An all-weather access for maintenance vehicles must be provided to all facility works. A vehicle access route shall also be provided to the edge of all SWM lakes suitable to carry maintenance vehicles and for use as a boat launch point. The access surface shall be a minimum of 4.5 m wide, shall extend into the lake beyond the lake edge at normal water depth to a point where the normal water depth is 1.0 m, and shall be accessible from and extend to a public road. Sharp bends are to be avoided, and it shall have a straight run of 12 m or more leading to the lake edge (to permit a straight run in for launching of boats). iii. Emergency Overflow Provisions The feasibility of an emergency overflow spillway is to be evaluated for each storage facility design and, where feasible, such provisions are to be incorporated in the facility design. The consultant is to identify the probable frequency of operation of the emergency spillway. Where provision of an emergency spillway or overflow route is found to be unfeasible, the design is to include an analysis of the impact of overtopping of the storage facility Schedule 4 - Design Standards 3. Drainage Page 87 of 130 and the probable frequency of occurrence of overtopping. The functional requirements of the spillway, and the impact analysis for the absence of one, are to consider the possible consequences of blockage of the system outlet or overloading due to consecutive runoff events, such that the storage capacity of the facility may be partially or completely unavailable at the beginning of a runoff event. iv. Landscaping Requirements Landscaping plans for areas bounding the facility shall be submitted as part of the Engineering Drawings. Landscaping of all proposed public lands included for purposes of the facility and of all proposed rights-of-way on proposed private property up to the design high water level, is to be part of the lake construction requirement and be dependant on the location and the context of the facility. The requirement for landscaping may be irrigated turf, constructed to the satisfaction of the Parks Department. v. Sediment Removal Provisions The facility design shall incorporate the ability for sediment capture and efficient removal for the control of solids, which may be washed to the facility. vi. Maintenance and Service Manual a. As part of the responsibility for design of a storm water management storage facility the development proponent shall prepare and provide a maintenance and service manual for the facility. b. Six complete copies of the manual are to be provided to the City of Revelstoke prior to the time when the operation responsibility of the facility is transferred to the City of Revelstoke, which will generally be at the time of substantial completion. The manual shall include complete equipment manufacturer's operation, maintenance, service and repair instructions, and complete parts lists for any mechanized or electrical equipment incorporated in the design. c. The manual is to include, at a minimum, the following information: I. A copy of the approved Engineering Drawings relating to the Storm water Storage Facility and appurtenances, updated to "As- Constructed". II. Schematic diagrams of the inlet and outlet arrangements, connections to and arrangement of upstream and downstream Schedule 4 - Design Standards 3. Drainage Page 88 of 130 systems, including all controls, shutoff valves, bypasses, overflows, and any other operation or control features. III. Location plans for all operating devices and controls, access points and routes, planned overflow routes, or likely point of overlapping in the case of exceedance of the design containment volume. IV. Stage Discharge Curves with clear relationships of the stages relative to surrounding features. vii. Signage for Safety The design for SWM Facilities shall include the installation of signage to warn of anticipated water level fluctuations, with demarcation of maximum water levels to be expected for design conditions. Warning signs will be provided and installed by the development proponent. viii. Engineering Drawing Requirements The engineering drawings for any SWM Facility are to include the following information, in addition to the physical dimensions: a. Stage-Volume and Stage-Area Curves; b. elevations at Normal Water Level (NWL), 5 Year Level and High Water Level (HWL); c. volumes at NWL, 5 year Level and HWL; d. freeboard elevation; e. notation indicating the lowest allowable building elevation for lots abutting the lake; f. contributing basin size (ha); g. measurements to locate submerged inlet(s), outlet(s) and sediment traps referenced to identifiable, permanent features which are not submerged at NWL. d) Design Details For Stormwater Management Lakes (Wet Ponds) i. Side Slopes a. Areas normally or infrequently covered by water, from the design high water level down to a point 1.0 m below the normal water level shall have a maximum slope of 5 (horizontal) to 1 (vertical). b. A slope of 3 (horizontal) to 1 (vertical) may be required from the 1.0 m depth point (below normal water level) to the pond bottom. The Schedule 4 - Design Standards 3. Drainage Page 89 of 130 requirement for maximized slopes below water is an attempt to discourage the growth of unwanted vegetation. c. In the case of constructed wetlands, benched areas above and below the NWL to encourage growth of aquatic and riparian plants is desirable. ii. Lake Bottom Material a. For areas where the groundwater table is below the NWL, the lake bottom and side slopes are to be composed of impervious material with a suitably low permeability (e.g. with a permeability coefficient in the order of 1 x 10 -6 cm/s). b. For areas where the groundwater table is expected to be near or above the NWL, the lake bottom may be of a pervious material as dictated by geotechnical considerations. iii. Circulation Requirements a. Narrow or dead bay areas where floating debris may accumulate are to be avoided. Inlets and outlets should be located with consideration of the need to maximize detention time and circulation within the lake water body. b. The length of the wet pond relative to the width should not be less than 3:1 or greater than 6:1 so as to promote natural water circulation and avoid water quality deterioration associated with stagnant reaches within the facility. iv. Outflow Control Works The outlet from a storm water management storage system must incorporate appropriate means for control of outflow. In addition, the outlet works must include provisions for operational flexibility, and to address unintentional blockage of the outlet and the possible need to either stop outflow or increase the rate of outflow. v. Draw down Provisions The means should be provided to permit discharge from storage facilities at the maximum rate of flow, which the downstream system can accommodate after storm runoff peak flows have passed and the flows from other contributing areas have decreased or ended. The rate of discharge to be provided for draw down purposes is to be sufficient to Schedule 4 - Design Standards 3. Drainage Page 90 of 130 restore availability of storage capacity of facilities sufficiently to accommodate subsequent runoff events within a reasonable time frame. To achieve this purpose, draw down of facilities is to be possible at rates to satisfy the following relationship of available volume to the time from commencing draw down with the facility at the design high level. Time After Commencing Draw down From Full Level Available Volume Required Below Design Full Level 24 hours Volume equivalent of 1 in 10 year run-off 72 hours 100% of total storage volume vi. Submergence of Inlets and Outlets Inlets and outlets are to be fully submerged, with the crown of the pipe at least 0.5 m below normal water level. Inlet and outlet pipe inverts are to be a minimum 0.1 m above the lake bottom. vii. Provision for Free Outfall from Inlets to Lakes The invert elevation at the first manhole upstream from the lake in a minor system shall be at or above the normal water level of the lake to avoid deposition of sediments in the inlet pipe. To avoid backwater effects on the upstream sewers leading to the lake, the obvert of the inlet sewer at the first manhole upstream from the lake shall be at or above the lake level for the 1 in5 year storm. A drop structure upstream from the lake will generally be required to achieve this. "Inlet" and "outlet" control calculations are required to verify the mode of operation of the lake inlets. viii. Provisions for Lowering the Lake Level The provision of the means to drain the lake completely by gravity drainage is desirable. The incorporation of this provision with the outlet control bypass should be considered. Where a gravity drain is not feasible, provisions are to be made in association with the outlet works or otherwise, so that mobile pumping equipment may be installed and used to drain the lake. ix. Lake Edge Treatment a. Edge treatment or shore protection is required and shall be compatible with the adjacent land use. The treatment used shall meet criteria for low Schedule 4 - Design Standards 3. Drainage Page 91 of 130 maintenance, safety, and ease of access to the waters edge. b. The edge treatment is to cover ground surfaces exposed or covered by water during a lake level fluctuation to 0.3 m below or above the normal water elevation, and shall be adequate to prevent erosion of the lake edge due to wave action. The typical acceptable edge treatment shall be, but is not limited to, a 250 mm deep layer of well graded washed rock with a 75 mm minimum size or vegetated strip consisting of hardy materials suitable for this application. c. The proposal of variations to the edge treatment minimum is encouraged. The final selection of edge treatment being subject to the approval of the City. e) Design Standards For Dry Ponds i. Outflow Control Works The outlet from a storm water management storage system must incorporate appropriate means for control of outflow. In addition, the outlet works must include provisions for operational flexibility, and to address unintentional blockage of the outlet and the possible need to either stop outflow or increase the rate of outflow. ii. Draw down Provisions The means should be provided to permit discharge from storage facilities at the maximum rate of flow, which the downstream system can accommodate after storm runoff peak flows have passed and the flows from other contributing areas have decreased or ended. The rate of discharge to be provided for draw down purposes is to be sufficient to restore availability of storage capacity of facilities sufficiently to accommodate subsequent runoff events within a reasonable time frame. To achieve this purpose, draw down of facilities is to be possible at rates to satisfy the following relationship of available volume to the time from commencing draw down with the facility at the design high level. Time After Commencing Drawdown From Full Level Available Volume Required Below Design Full Level 24 hours Volume equivalent of 1 in 10 year run-off 72 hours 100% of total storage volume Schedule 4 - Design Standards 3. Drainage Page 92 of 130 iii. Frequency of Operation All dry ponds shall be designed to temporarily detain excess runoff and thereby reduce the peak outflow rates to the connected downstream system. They shall not detain runoff for storms with post-development return periods of less than 2 years except where special provisions are made to facilitate clean up (i.e. paved bottom areas, etc.). iv. Depth of Ponding The maximum live storage limit in a dry pond is 3.0 m, as measured from the invert elevation of the outlet pipe. v. Dry Pond Bottom Grading and Drainage The dry pond shall be graded to properly drain all areas after its operation. The dry pond bottom shall have a slope of 1.0% or greater. Sub-surface drains or similar means may be required where it is anticipated that these slopes will not properly drain the dry pond bottom, or where dictated by multiple use or other special considerations. vi. Side Slopes 25% of the side slopes subject to inundation upon filling of the dry pond shall have a maximum slope of 5 (horizontal) to 1 (vertical). An alternate method of egress (e.g. stairs) may be required in steep areas. vii. Safety Provisions at Inlets and Outlets a. All inlet and outlet structures associated with dry ponds shall have grates provided over their openings to restrict access and prevent entry into sewers by children or other persons. A maximum clear bar spacing of 0.15 m shall be used for gratings. b. Grated outlet structures are to be designed with a hydraulic capacity of at least twice the required capacity to allow for possible plugging. Further, the arrangement of the structures and the location of the grating shall be such that the velocity of the flow passing through the grating will not exceed 1.0 m/s. Appropriate fencing and guard-rails are to be provided to restrict access and reduce the hazard presented by the structure headwalls and wingwalls. Schedule 4 - Design Standards 3. Drainage Page 93 of 130 viii. Other Considerations An on-stream dry pond may be constructed upstream of a road crossing as long as geotechnical evaluations conclude that construction is appropriate. Facilities must be constructed to allow overtopping without causing undue erosion or damage. All facilities on fish bearing streams shall be designed to pass fish. f) Design Standards For Infiltration Basins i. Outlet Design Infiltration basins do not have a formal outlet structure. As such, the storage volume must be based upon the complete runoff generated by the 1:100 year storm with no provision for outlet during the event, plus a 50% safety factor. ii. Depth of Ponding The maximum live storage limit in a basin is 3.0 m. iii. Side Slopes Side slopes subject to inundation upon filling of the basin shall have a maximum slope of 5 (horizontal) to 1 (vertical). iv. Safety Provisions at Inlets a. All inlet structures associated with infiltration basins shall have grates provided over their openings to restrict access and prevent entry into sewers by children or other persons. A maximum clear bar spacing of 0.15 m shall be used for gratings. b. Appropriate fencing and guard-rails are to be provided to restrict access and reduce the hazard presented by the structure headwalls and wingwalls. v. Other Considerations a. A detailed hydro geological investigation must be conducted to support the proposed infiltration basin. The investigation must assess impacts to upstream and downstream properties and identify measures to alleviate impacts, if necessary. b. To address the issue of sediment plugging during development in the Schedule 4 - Design Standards 3. Drainage Page 94 of 130 catchment area, the basin is to be constructed to 90% of its ultimate depth and volume. When development in the catchment reaches 90%, the infiltration basin is to be completed. 3.5 Erosion and Sedimentation Control All proposed projects must provide erosion and sedimentation controls to prevent the displacement of soil and the transport of sediment from the project site resulting from land-disturbing activities. To prevent the displacement of soil and the sediment transport during land-disturbing activities, Erosion and Sedimentation Control (ESC) measures are required and shall be performed as described below. Both temporary and permanent erosion and sedimentation controls shall be implemented. The objective of erosion and sedimentation control is to prevent the displacement of soil and the transport of sediment to streams, wetlands, lakes, drainage systems, and adjacent properties. Erosion on construction sites can result in excessive sediment transport to adjacent properties and to surface waters. Sediment transport can result in adverse impacts such as flooding due to obstructed drainage systems, smothering of aquatic habitat and the creation of algal blooms in lakes, among others. a) ESC i. The following ESC documents detail methods of control: a. Best Management Practices for Erosion & Sediment Control b. Land Development Guidelines for the Protection of Aquatic Habitat, Department of Fisheries and Oceans and the BC Ministry of Environment (1992) ii. In general, erosion and sedimentation controls shall address the following: a. Clearing Limits: Prior to any site clearing or grading, areas to remain undisturbed during project construction shall be delineated and marked on-site by flagging or other method. At a minimum, clearing limit delineation shall be installed at the edges of all sensitive area buffers. Retain existing vegetation, as much as possible. b. Cover Measures: Temporary and permanent cover measures shall be provided when necessary to protect disturbed areas as detailed in the ESC Documents. Temporary cover shall be installed if an area is to remain unworked for more than seven days, unless otherwise determined by the City. Any Schedule 4 - Design Standards 3. Drainage Page 95 of 130 area to remain unworked for more than 30 days shall be seeded or sodded, unless the City determines that winter weather makes vegetation establishment infeasible. Slopes and stockpiles 3H:1V or steeper and with more than 3 metres of vertical relief shall be covered if they are to remain unworked for more than 12 hours. The intent of these measures is to have as much area as possible covered during any period of precipitation. c. Perimeter Protection: Perimeter protection to contain sediment from sheet flow shall be provided down slope of all disturbed areas when necessary as detailed in the ESC Documents. Such protection shall be installed prior to upslope grading. Perimeter protection includes the use of vegetated strips, as well as more conventional constructed measures such as silt fences. d. Traffic Area Stabilization: Unsurfaced entrances, roads, and parking areas used by construction traffic shall be stabilized to minimize erosion and tracking of sediment offsite as detailed in the ESC Documents. e. Sediment Retention: Surface water collected from disturbed areas of the site shall be routed through a sediment pond or trap prior to release from the site as detailed in the ESC Documents, except areas at the perimeter of the site small enough to be treated solely with perimeter protection. Sediment retention facilities shall be installed prior to grading of any contributing area. f. Surface Water Controls: Surface water controls shall be installed to intercept and convey all surface water from disturbed areas to a sediment pond or trap and discharge it down slope of any disturbed areas as detailed in the ESC Documents, except areas at the perimeter of the site small enough to be treated solely with perimeter protection. Significant sources of upslope surface water that drain onto disturbed areas shall be intercepted and conveyed to a stabilized discharge point down slope of the disturbed areas. b) Implementation requirements i. ESC Plan Schedule 4 - Design Standards 3. Drainage Page 96 of 130 All proposed projects must submit a plan for providing ESC measures. All ESC measures shall conform to the details and specifications in the ESC documents unless the City approves an alternative. Construction within Sensitive Areas and Buffers Any construction that will result in disturbed areas on or within a stream or associated buffer, within a wetland or associated buffer, or within 15 metres of a lake shall be subject to the Best Management Practices for Erosion & Sediment Control - In-stream Works (1998). These provisions include phasing the project whenever possible so that construction in these areas is limited to the dry season. ii. Maintenance All ESC measures shall be maintained as per the Erosion and Sedimentation Control Plans. The consulting engineer shall be responsible for maintenance and review of ESC and for compliance with all conditions relating to ESC. iii. Final Stabilization Prior to obtaining total performance, the site shall be stabilized and the structural ESC measures (such as silt fences and sediment traps) shall be removed and drainage facilities cleaned as specified.

Highway 4.1 General a) Developments may require frontage roads, double frontage lots, deep lots with rear service lanes, or such other treatment as may be necessary in the public interest for the adequate protection of residential properties and to afford separation of through and local traffic. b) In reviewing engineering plans, the Approving Officer or Building Inspector must consider the sufficiency and suitability of the proposed road system, the arrangement, width, grade and location of all roads in relation to existing and planned roads, to topographical features, to public convenience and safety, and to the proposed uses of the land to be served by such roads. c) The arrangement of Highways in a Subdivision must either: i. provide for the continuation or appropriate projection of existing roads in surrounding areas; or ii. where topographic or other conditions make continuation or projection of existing roads impractical, provide an adequate and suitable highway system having regard to the uses of the land to be served. d) The dimensions, locations and standard of all roads in a proposed subdivision must conform substantially to any applicable community plan. e) Local residential roads must be aligned so that their use by through traffic will be discouraged. f) Cul-de-sac Roads, generally will not be permitted unless an adequate snow storage area is provided and approved by the Director of Engineering and Public Works. g) Walkways must be provided where they are deemed desirable to provide access through the subdivision to schools, playgrounds, shopping centres, greenways, wetlands and other community facilities or for proper circulation of pedestrian traffic. h) Jogs in Highway alignment at intersections may be allowed provided that the distance between centre lines is a minimum of 38 metres to maintain traffic safety. Intersections are to be designed and located within a range of angles between 70º and 110º. i) In the design of all street intersections, including those with lanes and walkways, the Consulting Engineer must give consideration to providing adequate sight and stopping distances for conflicting traffic streams involving pedestrians, bicycles and/or vehicles. The City of Revelstoke Traffic Regulation Bylaw No. 1400 prohibits sight obstruction greater than 1 m in height within 8 m of intersections. Schedule 4 - Design Standards 4. Highway Page 99 of 130 j) Road name signs and traffic signs required as a result of constructing or improving Roads must be provided by the City of Revelstoke at the expense of the Owner. k) Frontage improvements are required for all subdivisions and must adhere to the standards set forth in the City of Revelstoke Transportation Master Plan. This includes, but is not limited to, sidewalks, curbs and gutters, swales, and pathways. The City Engineer will decide if the developer must construct these improvements through a Works and Services Agreement or provide a cash-in-lieu payment based on a Professional Engineer's Construction Estimate. 4.2 Road Classification The roadway classification applicable to the Road under consideration will be determined from Table 1. Where topographical or other conditions make continuation or projection of an existing street impractical, the Director of Engineering and Public Works will review the Developer's proposal and may approve the alternative.

Notes: Through roads at an intersection are governed by the numbers shown in brackets, with the reduced grades on each side of the intersection for a distance equivalent to the "stopping sight distance". *Inverted Crowns (I.C.) and Normal Crowns (N.C.) shall be built with 2% crossfall unless otherwise approved. c) At road intersections, the minor road must be constructed with an approach grade of not greater than 3% for a distance of not less than 15 m from the adjacent edge of asphalt. d) All changes in gradient over 1.00% on arterial and collector Roads and over 2.00% on all other road classifications must be connected by vertical curves. Vertical curves must be designed in accordance with the latest edition of the Geometric Design Guide for Canadian Roads as published by the Transportation Association of Canada. e) Standard cross slopes (normal crown) must be 2.00% on all road classifications unless specified otherwise by the Director of Engineering and Public Works. Design road elevations must give due consideration to flood-proofing requirements of adjacent properties. Full road crossfall (reverse crown) may be considered in special circumstances, as a means of more closely matching property grade adversity on either side of the highway. Schedule 4 - Design Standards 4. Highway Page 103 of 130 f) The length of a transition from a normal cross-sectioned road to a section of road where there is super-elevation or crossfall must, in no case, be less than 70 m for a 50 kmh designed road or 110 m for a 70 kmh designed road. In selecting the length of the transition, care and consideration must be given to draining all of the pavement. Typically, if no horizontal spiral curve is used, 60% of the super- elevation is introduced prior to the beginning of the curve, and the balance is developed in the curve. g) Gutter elevations on curb returns must be shown on the drawings at the beginning, one-quarter points and end of curb returns. 4.4 Horizontal Alignment a) The horizontal centreline alignment of the road will be located on the centreline of the right-of-way, unless approved otherwise by the Director of Engineering and Public Works. Typical locations of works and utilities in Roads are shown on Standard Drawing COR-R3. b) Centreline chainage stations must be fully referenced and dimensioned from property lines. c) Minimum radius of curve and maximum super-elevation normally allowed are shown in Table 2 (Geometric Standards). The Minimum radius of curb return at intersections must be 7.50 m. Transitions in road widths, tapers, etc., must be formed with smooth curves and tangents, including no less than 30:1 for 50 km/h design speeds and preferably 40:1 tapers. d) A horizontal curve must be fully described showing internal angle, radius, tangent length and arc. e) Curb returns located on roads within industrial and commercial districts may require a larger radius to facilitate truck traffic and bus traffic, and will be as specified by the Director of Engineering and Public Works. f) When a new road with curbs intersects an existing road without curbs, full curb returns must be constructed. Full curb returns must be constructed at the intersection of two curbed roads. 4.5 Road Cross-Section The standard Road cross-section shall be as detailed in Table 1 and the City of Revelstoke Transportation Master Plan latest version. Note that the objectives of the standard road cross-sections as detailed in Table 1 and Updated Bylaw No. 2392 Schedule 4 - Design Standards 4. Highway Page 104 of 130 the Standard Drawings are the clear and intended goals on all roadways within the City of Revelstoke. It is recognized, however, that ambient conditions may require variance from these standards in existing and substantially "built-up" areas, where provisions to accommodate the required roadway modification may not have been anticipated. A variance to these standards may be considered by the Director of Engineering and Public Works. 4.6 Curb and Gutter, Sidewalks and Bike Lanes a) The standards for curbs, gutters, sidewalks and bike lanes shall be as detailed in Table 1 and in the MMCD Standard Drawings. b) Each property shall only have one (1) driveway access. Upon demonstrated need, more than one (1) driveway access may be granted and constructed for service stations, major commercial / industrial developments, or for residential developments that contain more than one (1) dwelling unit. Where a lot abuts a lane or road of different classification an additional driveway may be located to access the lane or road of the lower classification. c) Residential driveway access onto an arterial or collector road, is not permitted unless alternate access is impossible. Wherever physically possible, alternate local road or lane access shall be dedicated to preclude residential driveways accessing directly onto major roads. d) Residential driveway accesses serving corner lots shall be a minimum of 7 m from the lot corner nearest the intersection. All residential driveway accesses shall have a minimum width of 4 m and a maximum width of 6 m. e) Driveway accesses to commercial and industrial corner lots shall be a minimum of 15 m from the property line of the adjoining road. The maximum width of a driveway to a commercial or industrial property having only one access shall be 11 m. and the maximum width of each driveway to a commercial or industrial property having more than one access shall be 9 m. unless otherwise approved by the Director of Engineering and Public Works. f) At the discretion of the Director of Engineering and Public Works, access to large parking areas may be by curb returns rather than a driveway letdown. The Director of Engineering and Public Works may require deceleration and acceleration lanes for access off major roads for safety reasons and to minimize disruption to traffic flows. Design of such access shall follow the recommendations in the Ministry of Transportation & Highways, Highway Engineering Branch Design Manual.

Highway Page 107 of 130 a) Subject to prior approval by the City of Revelstoke, the previous design guidelines may be modified for hillside neighbourhoods as outlined below. Hillside areas are lands that in their natural state have a slope angle of 10% or greater for a minimum horizontal distance of 10 metres. The design objective of the Hillside standards include the following: i. Accommodation of hillside land development while minimizing environmental ii. Impacts such as disturbance of natural slopes, vegetation and watercourses. iii. Protecting development from hazardous conditions. iv. Encouragement of low speed traffic, particularly for local roads. v. Development of site layouts compatible with the above objectives. b) Modification to the following Hillside standards may be considered by the City of Revelstoke for specific developments, provided that the proposed modifications are supported by adequate research and detailed justification. Hillside road cross section elements should conform to Table 1 of this bylaw and the Transportation Master Plan. Any reduction in the right-of-way (ROW) width may be considered based on the recommendation of the developer's engineer and must be approved by the Director of Engineering (or designate). New Hillside development should: i. be in harmony with the surrounding community and the natural environment; ii. protect wildlife habitat and environmentally sensitive areas; iii. integrate or protect unique or special natural features of the site such as landforms, rock outcroppings, mature trees and vegetation, drainage courses, hilltops and ridgelines; iv. avoid unstable or hazardous portions of the site and protect lives and property from hazardous conditions such as landslides, erosion, etc. v. provide safe access for residents, visitors and service providers; Updated Bylaw No. 2392 Schedule 4 - Design Standards 4. Highway Page 108 of 130 vi. maintain the aesthetic and scenic quality of the City of Revelstoke hillsides; vii. be compatible with the natural features, building location and existing open spaces of neighbouring properties; viii. respect the existing views, privacy, access to light and safety of neighbouring properties; and ix. support economic and efficient construction and maintenance standards. Schedule 4 - Design Standards 4. Highway Page 109 of 130 i. Roads: Subject to approval by the City of Revelstoke, maximum grades may be increased to 2% greater than those shown in Table 2. ii. Cul-de-Sac Streets and Hillside Emergency Accesses Some of the Local streets within complex topographic areas will take the form of a cul-de-sac. Generally, cul-de-sac streets are used where street connectivity is not possible (i.e. steep terrain) or not warranted (i.e. serves very few homes). Although the appropriate Local street standard will also apply to cul-de-sac streets, there are two additional street specifications unique to this street form that must be addressed in relation to livability: permitted length and the design of the street turnaround. In complex topographic areas long streets may be required to access developable pockets within areas of steep terrain. Due to the complex topography it will often not be advisable, or even possible, for connectivity to be achieved at both ends of a street. Longer cul-de-sac streets will result and systems of branching cul-de-sacs will be established to access some areas of extremely difficult terrain. In response to public safety issues, it is desirable that emergency access routes to such areas are available - Hillside Emergency Access standards are included below. This is considered more acceptable from a livability stance than requiring street connectivity in all situations as the lower standards required for an emergency access will result in a lesser impact to the hillside. Maintaining street connectivity wherever possible will remain a priority. The radius of a cul-de-sac also plays a role in the livability of a street. Laying a cul-de-sac requires a relatively large flat area. The larger this area is, the greater the impact to the landscape, particularly in complex topographic areas. Large cul-de-sacs can also decrease the social quality of a street by terminating the public corridor with a large, barren paved surface. A reduction of the cul-de-sac radius is feasible if parking is restricted in the cul-de-sac, which will ensure a large enough circumference for car turning. It is noted that provision must be made on a case by case basis for emergency vehicle turning. Schedule 4 - Design Standards 4. Highway Page 110 of 130 a. Cul-de-sac i. ROW: min 13.0m radius; ii. Radius to edge of paved surface: min 12.0m radius; iii. Alternative types of street turnarounds will be considered for use based on site iv. specific topographic conditions. In certain circumstances reduced cul-de-sac radii or hammer head type turnarounds will be permitted. v. Cul-de-sac streets may exceed the maximum length as specified by the City of Revelstoke - mid-block turnarounds should be considered in this situation; vi. A secondary emergency access must be provided for all public cul- de-sac streets that are in excess of the maximum length as specified by the City of Revelstoke. vii. Cul-de-sac Roads are designed to be permanent, must be provided at the closed end with an area designed to permit safe and adequate space for the turning of motor vehicles. viii. At road intersections cul-de-sac must be constructed with an approach grade of not greater than 3% for a distance of not less than 15 m from the adjacent edge of asphalt of the major road. ix. The draining grade around the outside curb of a cul-de-sac must be not less than 0.50% and not greater than 5.00%. Longitudinal gradients of cul-de-sac bulbs shall not exceed 5.00%. x. When a cul-de-sac is at the bottom of a hill, the longitudinal gradient of the first 50m of roadway uphill from the cul-de-sac bulb shall not exceed 5.00%. The maximum longitudinal gradient for the rest of the hill shall not exceed 8.00%. xi. When a cul-de-sac is at the top of a hill, the longitudinal gradient for the roadway downhill from the cul-de-sac must not exceed 12.00%. Schedule 4 - Design Standards 4. Highway Page 111 of 130 xii. Gutter elevations on curb returns and cul-de-sacs must be shown on the drawings at the beginning, one-quarter points and end of curb returns and at 7.50 m intervals around cul-de-sacs. xiii. A turn-around or a second point of access is required on roads longer than 100 m. The maximum length of a permanent cul-de- sac shall be 200 m. Where it is part of a temporary and/or staged development, this maximum length may be 400 m. Cul-de-sac lengths greater than 200 m may be considered by the Approving Officer. xiv. Major flood routes must be provided on down slope cul-de-sacs xv. Snow storage areas must be provided in close proximity. b. Hillside Emergency Access: Guidelines for emergency access roads at long cul-de-sacs include the following: i. Maximum grade: 15% ii. Minimum right-of-way and roadway width: 4.5m. iii. Removable bollards to prevent access by non-emergency vehicles. iv. Pavement structure equivalent to local road. v. Shared use with pedestrian walkway or bikeway. c.
