Creating Accessible Outdoor Spaces

Creating Accessible Outdoor Spaces is a critical aspect of the Advanced Certificate in Universal Design for Disability Housing. This section focuses on key terms and vocabulary that are essential to understanding how to create accessible outdoor spaces for people with disabilities. The following terms are explained in detail, along with examples and practical applications:

1. Accessible Route: An accessible route is a continuous, unobstructed path that connects all accessible elements and spaces within a site. It should be stable, firm, and slip-resistant and must comply with the technical specifications outlined in the Americans with Disabilities Act (ADA) Standards for Accessible Design.

Example: An accessible route might include a concrete sidewalk, a ramp, and an accessible parking space.

Practical Application: When designing an outdoor space, it's essential to ensure that an accessible route connects all critical areas, such as building entrances, outdoor seating areas, and restrooms.

2. Clear Space: A clear space is an area that is free from obstructions and provides enough room for a person using a mobility device, such as a wheelchair, to maneuver.

Example: A clear space might be a 60-inch by 60-inch area that provides enough room for a wheelchair to turn around.

Practical Application: When designing outdoor spaces, it's essential to provide clear spaces at entrances, seating areas, and other critical locations to ensure that people with disabilities can access and use these areas safely.

3. Grading: Grading refers to the slope or pitch of a surface, such as a sidewalk or ramp.

Example: A sidewalk with a slope of 1 inch per foot is considered a properly graded surface.

Practical Application: When designing outdoor spaces, it's essential to ensure that all surfaces are properly graded to prevent water pooling and to provide a stable, slip-resistant surface for people with mobility devices.

4. Knee and Toe Clearance: Knee and toe clearance refers to the space between the ground and any obstructions, such as handrails or benches, that a person using a mobility device needs to approach and use an element safely.

Example: A bench with a knee and toe clearance of 9 inches provides enough space for a person using a wheelchair to approach and transfer onto the bench safely.

Practical Application: When designing outdoor spaces, it's essential to provide adequate knee and toe clearance at all elements, such as benches, drinking fountains, and handrails, to ensure that people with disabilities can use them safely.

5. Protruding Objects: Protruding objects are any objects that extend from a wall or other surface and protrude more than 4 inches from the surface or at or below waist level.

Example: A sign that extends more than 4 inches from a wall is a protruding object.

Practical Application: When designing outdoor spaces, it's essential to avoid protruding objects or provide cane-detectable barriers to ensure that people with visual impairments can safely navigate the space.

6. Tactile Warning Surface: A tactile warning surface is a textured surface that provides a warning to people with visual impairments that they are approaching a hazard, such as a street crossing or a drop-off.

Example: A tactile warning surface might be a series of truncated domes that are installed at the edge of a platform or at a street crossing.

Practical Application: When designing outdoor spaces, it's essential to provide tactile warning surfaces at all hazards to ensure that people with visual impairments can navigate the space safely.

7. Visual Contrast: Visual contrast refers to the difference in color or brightness between two objects or surfaces.

Example: A door with a white frame and a red door provides good visual contrast.

Practical Application: When designing outdoor spaces, it's essential to provide visual contrast between critical elements, such as doors, handrails, and seating areas, to ensure that people with visual impairments can use them safely.

8. Wheelstop: A wheelstop is a device that is installed at the end of a parking space to prevent vehicles from encroaching on the accessible route.

Example: A wheelstop might be a piece of rubber or plastic that is installed at the end of a parking space.

Practical Application: When designing outdoor spaces, it's essential to install wheelstops at all accessible parking spaces to ensure that people with disabilities can safely enter and exit their vehicles.

In conclusion, understanding the key terms and vocabulary related to creating accessible outdoor spaces is critical to ensuring that people with disabilities can use and enjoy these spaces safely. By providing accessible routes, clear spaces, proper grading, adequate knee and toe clearance, avoiding protruding objects, providing tactile warning surfaces, visual contrast, and wheelstops, designers can create outdoor spaces that are inclusive and accessible to all.

When designing outdoor spaces, it's important to keep in mind that accessibility is not just a requirement but a right for everyone. By incorporating these key terms and concepts, designers can create spaces that are safe, functional, and welcoming for people with disabilities.

Designers should also consider the unique challenges and needs of people with different types of disabilities. For example, people with visual impairments may require tactile warning surfaces and visual contrast, while people with mobility impairments may require clear spaces and adequate knee and toe clearance.

Furthermore, designers should consult with people with disabilities and disability organizations to ensure that their designs are accessible and inclusive. By working together, designers and people with disabilities can create outdoor spaces that are accessible, functional, and welcoming to everyone.

In summary, creating accessible outdoor spaces requires a deep understanding of key terms and vocabulary, including accessible route, clear space, grading, knee and toe clearance, protruding objects, tactile warning surface, visual contrast, and wheelstop. By incorporating these concepts into their designs, designers can create outdoor spaces that are safe, functional, and welcoming for people with disabilities. By consulting with people with disabilities and disability organizations, designers can ensure that their designs are truly accessible and inclusive.
