(#615)Imperviousness factor for mixed use project


I would like to know the recommended imperviousness factor for the mentioned project considering its diversity in building typologies- hospital, staff quarters, hostel, and college. NBC specifies factors only for Commercial/Industrial, Residential and underdeveloped lands/parks.


Considering the diversity in the building typologies as mentioned in the query, please proceed with calculations considering imperviousness factor for commercial/industrial areas by NBC-2005.
