A.

The Zoning Administrator, Planning Commission, or the City Council on review, shall make the following findings in addition to any other required findings required by this title before approving any development application in the DIPSA:

1.

The proposed project is consistent with the DIPSA Specific Plan;

2.

The proposed development and/or construction standards of the proposed project are consistent with the development and construction standards of the DIPSA Specific Plan, as well as all other applicable City standards and codes;

3.

The uses and structures will constitute an orderly, attractive and harmonious development; foster stability of land values and investments; and promote the general welfare, by preventing the establishment of uses or the erection or maintenance of structures having unsightly, undesirable or obnoxious characteristics or which are not properly related to their sites, surroundings or traffic circulation in the vicinity, or which would not meet the specific intent clauses or performance standard requirement of the zoning ordinance of Union City.

B.

If the Zoning Administrator, Planning Commission or Council makes the necessary findings, it shall approve the application. If the Zoning Administrator, Planning Commission or Council finds to the contrary, it shall disapprove the application or approve subject to such specified conditions, changes or additions as will assure the development will comply with the provisions of the Specific Plan and this district.
