1. What is Sidewalk Slope Calculation?

Sidewalk slope calculation determines the percentage grade of a concrete sidewalk, which is crucial for proper drainage and accessibility compliance. The slope is expressed as a percentage representing the vertical rise relative to the horizontal run.

2. How Does the Calculator Work?

The calculator uses the slope formula:

Where:

• \( Rise \) — Vertical height difference (meters)
• \( Run \) — Horizontal length (meters)

Explanation: The formula calculates the slope percentage by dividing the vertical rise by the horizontal run and multiplying by 100 to convert to a percentage.

3. Importance of Proper Slope

Details: Proper sidewalk slope is essential for ADA compliance, water drainage, and safety. Most building codes require a cross slope of 1-2% for proper drainage and a maximum slope of 5% for accessibility.

4. Using the Calculator

Tips: Enter the vertical rise and horizontal run in meters. Both values must be positive numbers. The calculator will compute the slope percentage.

5. Frequently Asked Questions (FAQ)

Q1: What is the maximum slope for ADA compliance?
A: The maximum running slope for ADA compliance is 1:20 (5%). Cross slopes must be no greater than 1:50 (2%).

Q2: How do I measure rise and run?
A: Measure the vertical height difference (rise) and the horizontal distance (run) between two points on the sidewalk.

Q3: What's the minimum slope for drainage?
A: A minimum slope of 1% (1:100) is typically recommended for proper water drainage.

Q4: Can I use different units of measurement?
A: This calculator uses meters, but the formula works with any consistent unit (feet, inches, etc.) as long as both measurements use the same unit.

Q5: How accurate should slope measurements be?
A: For construction purposes, slope measurements should be accurate to within 0.1% to ensure proper drainage and compliance with accessibility standards.
