Changes in elevation
Ground surfaces along routes shall be free of vertical rises that impose barriers for users of mobility aids and strollers, or that create tripping hazards.
Only a minor vertical rise is permitted within an accessible route, per the following information:
Where sloped surfaces are included, the slope along a walkway and in curb ramps should be 1:20 (5 percent) or less. Any slope greater than this is considered a “barrier-free ramp” and must be designed in accordance with the Manitoba Building Code.
The cross slope on walking surfaces shall not exceed 1:50 (2 percent)
Curb ramps
These may be required to provide access from the parking surface to an adjacent raised pedestrian area. Where two curb ramps are needed to provide a pedestrian crossing across a vehicle drive aisle, the curb ramps should include a detectable warning panel. For dimensional and layout guidance, see City construction specs SD-229.
Optional: If raised sidewalks are provided to cross vehicle drive aisles, they should be designed to include curb ramps with detectable panels, and to ensure that the slope of the ramps used by vehicles have a maximum slope of 5 percent.
Recommended design criteriaProvide directional signage where there is a change in direction along a pedestrian route and where the intended destination of the route it not clearly evident.Provide a level of illumination of at least 50 lux along the entire route.Where vertical objects are adjacent to a route, the surface surrounding the objects must differ in texture and colour from the routes.Questions?
