1. What Is Sidewalk Slope Calculation?

Sidewalk slope calculation determines the gradient or incline of a sidewalk surface, expressed as a percentage. It's essential for ensuring accessibility, drainage, and safety compliance in pedestrian pathways.

2. How Does The Calculator Work?

The calculator uses the slope formula:

Where:

• \( Height \) — Vertical rise in feet
• \( Distance \) — Horizontal run in feet

Explanation: The formula calculates the slope percentage by dividing the height by the distance and multiplying by 100 to convert to a percentage.

3. Importance Of Slope Calculation

Details: Proper slope calculation is crucial for ADA compliance, preventing water accumulation, ensuring wheelchair accessibility, and maintaining pedestrian safety on sidewalks and ramps.

4. Using The Calculator

Tips: Enter height and distance in feet. Both values must be positive numbers. The calculator will compute the slope percentage.

5. Frequently Asked Questions (FAQ)

Q1: What is the maximum allowable slope for ADA compliance?
A: The maximum slope for accessible routes is 1:12 (8.33%) for ramps, while sidewalks typically have much gentler slopes.

Q2: How is slope different from angle?
A: Slope is expressed as a percentage or ratio, while angle is measured in degrees. Slope percentage = tan(angle) × 100.

Q3: Why multiply by 100 in the formula?
A: Multiplying by 100 converts the decimal result to a percentage, which is the standard way to express slopes in construction and accessibility guidelines.

Q4: Can I use different units of measurement?
A: Yes, but both height and distance must use the same units (both in feet, both in meters, etc.) for accurate results.

Q5: What slope is considered too steep for sidewalks?
A: Generally, slopes greater than 5% may be challenging for wheelchair users and should include level landing areas at regular intervals.
