1331.01 DISTRICTS ESTABLISHED AND DESCRIBED.
   Two districts, I1 and I 2, are established to meet the present and future needs of the City for industrial development. Residential use is permitted in the I1 District, but is excluded from the I 2 District. Where permitted, residential and business uses must conform to the requirements set forth for them in Sections 1323.04 and 1327.05 respectively. The specific requirements for industrial uses in these districts are given in Sections 1331.07 and 1331.08. For contingent and special exceptions in the Industrial Districts see Sections 1335.03 and 1339.04. A brief description of the industrial districts follows:
   (a)   I1. This district will incorporate most of the existing industrial developments and provide for their expansion. Generally the permitted uses will include only those where all of the operations, including the storage of materials, are confined within a building and the performance characteristics are compatible with uses permitted in neighboring districts. Residences and business are permitted.
   (b)   I2. This district will incorporate many existing industrial developments and provide for their expansion and will assure adequate areas for new industrial development. Realizing the need for industrial expansion, the I2 District does not permit dwellings. (1969 Code §27-32)
