1. What is Lot Coverage?

Lot coverage is the percentage of a property's total area that is covered by structures and impervious surfaces. It is an important metric in urban planning and zoning regulations to control development density and manage stormwater runoff.

2. How Does the Calculator Work?

The calculator uses the lot coverage formula:

Where:

• \( Structures \) — Total area of all structures on the lot (sq ft)
• \( Impervious \) — Total area of impervious surfaces (sq ft)
• \( Lot\ Size \) — Total area of the lot (sq ft)

Explanation: The formula calculates the percentage of the lot that is covered by buildings and other impermeable surfaces that prevent water absorption into the ground.

3. Importance of Lot Coverage Calculation

Details: Calculating lot coverage is essential for compliance with local zoning regulations, managing stormwater drainage, maintaining green spaces, and ensuring proper urban development planning.

4. Using the Calculator

Tips: Enter the total square footage of structures, impervious surfaces, and the total lot size. All values must be in square feet and greater than zero. The lot size must be larger than the sum of structures and impervious areas.

5. Frequently Asked Questions (FAQ)

Q1: What counts as impervious surface?
A: Impervious surfaces include paved areas, concrete, asphalt, rooftops, and any other surfaces that prevent water from soaking into the ground.

Q2: Why is lot coverage important?
A: Lot coverage regulations help manage stormwater runoff, prevent flooding, maintain groundwater recharge, and control urban density for better living environments.

Q3: What is a typical maximum lot coverage percentage?
A: Maximum lot coverage varies by zoning district but typically ranges from 30% to 60% depending on the area and type of development.

Q4: Do decks and patios count in lot coverage?
A: Yes, if they are impervious surfaces. Porous pavers or gravel might be calculated differently depending on local regulations.

Q5: How accurate do measurements need to be?
A: For regulatory compliance, precise measurements from site plans or surveys are recommended. For estimates, reasonable approximations are acceptable.
