The heavy industrial district is established to provide areas in the City where heavy industrial, manufacturing, processing, assembly, fabricating and ancillary activities can occur while being protected from encroachment of commercial and residential uses. This district is intended to permit high-intensity land uses that would be termed obnoxious due to noise, glare and other emissions resulting from the manufacturing process. This district is intended to apply only to those Port-owned lands to which this zone was applied upon the formation of this district. [Ord. 3354 § 2, 1999; Code 1970 § 25.56.010.]
