Notas do Editor
I would at least give a range for the unit pavers, otherwise, kinda useless to have them here.
Clarify last bullet: Reduction in porosity with age is a reality….
I assume here you will talk about what the underlying soil permeability is or is estimated to be.
Is the range really 0 to 100%? No runoff from a 10 year storm with .22 in/hr max infiltration? I suppose there must be no pre-existing storage in the reservoir layer when the storm hits. Should note that.
Interesting. You should note here when you discuss this what the 100 year rainfall depth is for the area.
