Boardwalks are generally described as planked structures built close to the ground or over wet soil or water. They can allow people who use mobility aids or who have poor balance to traverse through wet or soft areas. The Standard provides organizations with minimum requirements for boardwalks on recreational trails.
The requirements in this section represent a baseline for accessibility. Organizations are free to exceed the minimum requirements and provide greater accessibility based on local need, existing topography design opportunities and budget realities.
It should be noted that this requirement does not mandate that recreational trails must include boardwalks.
The requirements of this Section apply to boardwalks located on newly constructed or redeveloped recreational trails that an organization intends to maintain.
Requirements for the Design of Boardwalks in Recreational Trails
- Clear width
- Minimum 1,000 mm.
- Clear height
- Minimum 2,100 mm headroom clearance above boardwalks.
- Running slope
- Boardwalks with running slopes steeper than 1:20 (5%) must be designed as ramps and meet the applicable requirements. See Section 2.2.3 Ramps in Recreational Trails.
- Must be firm and stable.
- Surface openings
- Openings in the boardwalk must not allow the passage of an object more than 20 mm in diameter.
- Edge protection
- Provide edge protection that is minimum 50 mm high.
