"I" is used to indicate a zoning district primarily intended to accommodate industrial uses. "IRMX" is used to indicate a zoning district that mixes industrial and other nonresidential use as well as residential development. "ICMX" is used to indicate a zoning district that mixes commercial and industrial. 253.1
(.b)   The numeral following the dash in the Industrial district map symbols is a relative indicator of the density/intensity or use, with a "1" indicating the lowest intensity/use option.
(b)   Purposes.
(.1)   Philadelphia's Industrial zoning districts are primarily intended to accommodate manufacturing, warehousing, wholesale, and industrial uses. The district regulations are intended to:
(.a)   promote the economic viability of utilities, construction, manufacturing, goods movement and warehousing, resource production, research and development, equipment and facility services, and other industrial uses;
(.b)   encourage employment growth; and
(.c)   limit the encroachment of unplanned residential and other non-industrial development within active industrial areas.
