This methodology translates input parameters, such as land use and square footage, into a quantifiable number of required parking spaces. Understanding this process is essential for interpreting the results and ensuring adequate parking provisions.
-
Land Use Coefficients:
Different land uses have varying parking demands. A parking ratio calculator utilizes land use coefficients, derived from local zoning ordinances or established best practices, to reflect these differences. For instance, a restaurant might have a higher coefficient than an office building of the same size due to anticipated peak demand. These coefficients are crucial for accurately reflecting the unique parking needs of diverse developments.
-
Gross Floor Area:
The gross floor area of a building is a primary driver of parking demand. Calculators often use this metric in conjunction with land use coefficients to determine the total parking requirement.
