The intent and purpose of the P-U zone is to provide for certain public utility and related uses subject to a precise development plan procedure to:
A. 
Insure compatibility of the development with the general plan and the surrounding developments;
B. 
Insure that due regard is given to environmental factors;
C. 
Provide for public improvements and other conditions of approval necessitated by the development.
(Ord. 9060 § 1390; Ord. 9268 § 1, 1971; Ord. 9441 § 1, 1975)
A. 
In a P-U zone, notwithstanding any other provision of this title, only the uses listed in Table A, below, shall be permitted, subject to the requirements and development standards specified by this chapter, and subject to the provisions of Chapter 21.44 of this title governing off-street parking requirements.
B. 
The uses permitted by conditional use permit, as indicated in Table A, shall be subject to the provisions of Chapter 21.42 of this title. Approval of a conditional use permit is required for the generation and transmission of electrical energy and shall require a finding by the City Council that the use serves an extraordinary public purpose in addition to the other findings required for a conditional use found in Chapter 21.42.
C. 
A use similar to those listed in Table A may be permitted if the City Planner determines such similar use falls within the intent and purposes of the zone, and is substantially similar to the specified permitted uses.
D. 
A use category may be general in nature, where more than one particular use fits into the general category (ex. in some commercial zones "office" is a general use category that applies to various office uses). However, if a particular use is permitted by conditional use permit in another zone, the use shall not be permitted in this P-U zone (even under a general use category) unless it is specifically listed in Table A of this chapter as permitted or conditionally permitted.
