| #Verify the drainage area directed to any proposed porous pavement. If DCIA runoff from other areas on-site, in addition to the direct (1:1) rainfall onto the porous pavement, is directed onto porous pavement, the porous pavement cannot be considered disconnected. It must instead be considered, and modeled as, a porous pavement structural SMP. The porous surface must be considered, and modeled as, DCIA. Porous pavement structural SMPs require infiltration testing. [Section 4.2.1] | | #Verify the drainage area directed to any proposed porous pavement.
