Question
Which formula is used for calculation of the percentage of restoration area?
A. Percentage of restoration area = (Disturbed area I Restoration site area) x 100
B. Percentage of restoration area = (Restoration area / Total previously disturbed site area) x 100
C. Percentage of restoration area = (Restoration area / Total proposed restoration site area) x 100
D. Percentage of restoration area = (Restoration area / Total previously undisturbed site area) x 100
Answer
The correct formula for calculating the percentage of restoration area is:
B. Percentage of restoration area = (Restoration area / Total previously disturbed site area) x 100
Explanation
This formula is used to calculate the percentage of restoration area for the LEED v4 credit SSc2: Protect or Restore Habitat. The restoration area is the portion of the site that is restored with native or adapted vegetation, and the total previously disturbed site area is the area that was altered by human activity before the project.
This formula takes the restoration area and divides it by the total previously disturbed site area, then multiplies the result by 100 to express it as a percentage.
Option A is incorrect because it uses “Disturbed area” instead of “Restoration area” in the numerator, and “Restoration site area” instead of “Total previously disturbed site area” in the denominator.
Option C is incorrect because it uses “Total proposed restoration site area” in the denominator, which is not the correct basis for the calculation.
Option D is incorrect because it uses “Total previously undisturbed site area” in the denominator, which is not relevant to the calculation of restoration area percentage.
To calculate the percentage of restoration area accurately, you must use the actual restoration area in the numerator and the total area of the site that was previously disturbed in the denominator. This will give you the proportion of the previously disturbed site that has been restored, expressed as a percentage.
