Maximum road profile grade of 5%, except where minimal grading is required to protect environmentally sensitive features, i.e., woodlots, wetlands, aquifers, etc.A 2.0m easement for Municipal and Enbridge Gas purposes is required along both sides of all road allowances within the limits of the subdivision.Interim grading of road allowances must not interfere with surface drainage.Consultant to prepare a detailed pavement grading plan to ensure drainage along curb returns. Where the crown of the intersecting through road is maintained, crossfall of the through road is to be limited to 1% in the intersection.Generally, only single catch basins will be required at these low points. A negative grade (a slope downward from the edge of the pavement) of 1% to 2% should be created at intersections for a minimum distance of 5 meters on all road profiles where internal streets intersect with collectors and through roads, if feasible.Vertical curves are required where the road grade change is greater than 1.0 %.See Volume 5 for more grading information.City streets must be designed as per Transportation Master Plan.is required for all new hydro installations. boulevard width of 4.5m is required to accommodate a 1.8m wide sidewalk and underground hydro vaults/transformers, including their grounding grid. Minimum tangent length at intersection (m) Maximum grade for through roads at intersections (%) These standards outline the City’s minimum expectations, and any deviation will require specific review and approval by the City Project Manager before implementation of a project.Īll roadwork including asphalt, concrete curbs, granular, base, subbase, subgrade preparation and boulevard requirements shall be completed to OPS and in accordance with the following Municipal specifications (Table V4-1): Table V4-1: Geometric parameters for urban roads Road classification This includes the design and implementation of roads, trails, pathways, sidewalks and other transportation elements.ĭeviation from the standards within will be expected on projects where matching existing conditions are required. This Volume of the City of Waterloo Comprehensive Engineering and Landscape Manual, Volume 4: Transportation, is intended to provide the user with the general expectations of projects relating to transportation elements in the City of Waterloo. This document may be updated on an annual basis or at the discretion of the Director of Engineering Services. This volume outlines transportation standards which include design and implementation of roads, trails, sidewalks, bicycle lanes and any other transportation elements.
