==To calculate the require facility area or footprint where the depth is constrained (1D)==
In many locations throughout Ontario, there may be limited depth of soil available into which stormwater may be infiltrated. In this case the required storage needs to be distributed more widely across the landscape. The overall are of BMP required can be calculated:
<math>P=\frac{IiD}{nd+qD}</math>
<math>P=\frac{IiD}{nd+qD}</math>
(The rearrangement to calculate the required footprint area of the facility for a given depth using three dimensions of underground infiltration is not available at this time. Elegant submissions are invited.)
