This chapter is established to provide standards and regulations, consistent with the City's general plan and the purposes and provisions of this title, for office areas in the City.

Large office buildings should be well buffered from residential areas with landscaped open space. Buildings and signs should be coordinated with high quality materials and architecture.

1. Development Review: Uses proposed in the P-O Zone may only be established in conformance with the City's development review procedures of the City. Applicants shall follow the procedures and requirements of this Code regarding development review in the preparation and review of development proposals in the P-O Zone. All uses shall be conducted according to the approved plan or plat and any conditions of approval. Plans or plats may not be altered without prior approval of the City, except as allowed under State law. Office condominiums may be approved in accordance with State law and City ordinances.
