1. What is Parking Lot Slope?

Parking lot slope refers to the gradient or incline of a parking surface, typically expressed as a percentage. It's calculated by dividing the vertical rise by the horizontal run and multiplying by 100.

2. How Does the Calculator Work?

The calculator uses the slope percentage formula:

Where:

• \( \text{rise} \) — Vertical change in feet
• \( \text{run} \) — Horizontal change in feet

Explanation: The formula calculates the percentage grade of a slope, which is essential for proper drainage and accessibility in parking lot design.

3. Importance of Slope Calculation

Details: Proper slope calculation ensures adequate drainage, prevents water accumulation, meets accessibility requirements, and complies with building codes and regulations.

4. Using the Calculator

Tips: Enter the vertical rise and horizontal run measurements in feet. Both values must be positive numbers greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is the maximum slope allowed for parking lots?
A: Typically, parking lot slopes should not exceed 5% for accessible parking spaces and 8-10% for general parking areas, but local regulations may vary.

Q2: Why is proper slope important in parking lots?
A: Proper slope ensures effective drainage, prevents water pooling, reduces ice formation in cold climates, and provides safe vehicle movement.

Q3: How do I measure rise and run for slope calculation?
A: Rise is the vertical height difference between two points, while run is the horizontal distance between those same two points.

Q4: Can this calculator be used for other slope calculations?
A: Yes, the same formula applies to any slope calculation, though the units should be consistent (both measurements in the same unit).

Q5: What's the difference between slope percentage and slope ratio?
A: Slope percentage expresses the gradient as a percentage (rise/run × 100), while slope ratio expresses it as a ratio (rise:run).
