The purpose of the I-3 (heavy industrial) district is to provide an environment for and conducive to basic or primary industries and related industrial activities requiring the use and storage of bulk quantities of raw or scrap materials for processing to semi-finished or finished products. The district is intended to encourage sound heavy industrial development by providing and protecting areas within the city for such development, subject to regulations necessary to ensure the purity of the air and groundwater in the Livermore planning area, and the protection of nearby uses of land from hazards, noise, or other radiated disturbances. (Ord. 442 § 14B.10)

The following are the principal permitted uses in an I-3 district:

A. All of the uses permitted in the I-2 district.

• D. Vehicle dismantling yards, scrap and waste yards.

E. Any land use that utilizes hazardous materials shall be subject to the regulations of Chapter 3-30 LPZC.
