Potential lawn ratio

FIGURE 2.2 Potential lawn ratio, Franklin County, Ohio. 

Compiling tax assessor data, we developed two measures of lawn size that can be calculated at either the household or census tract levels the Potential Lawn Area (PLA) and the Potential Lawn Ratio (PLR). The PLA of a residence is determined by subtracting the footprint of the house, calculated as the house square footage (h) divided by number of floors (s), from the overall lot size (1).
