Line 30:
Line 30: − − When sizing the area of permeable paving (A<sub>p</sub>) based on the total contributing drainage area (A<sub>c</sub>) = A<sub>i</sub> + A<sub>p</sub>, the following equation may be used: − <math>A_{p}=\frac{Q_c\times A_c}{V_R\times (d_p – P + (q'\times t))}</math>

Where the storage reservoir depth is fixed or constrained the footprint area of the permeable pavement (and associated water storage reservoir), A<sub>p</sub> can be calculated as follows:<br>
