The purpose of a development agreement is to provide a vehicle for development in areas and for uses where, in the opinion of the city council or the planning and zoning commission, approval of a requested rezone by itself does not satisfy the requirements set forth in this title for rezone approval; but, that use of a development agreement will assure compliance with the required rezone findings and conclusions. Development agreements can be used after a determination has been made that the proposed rezone by itself is not appropriate, unless the use of a development agreement could allow development to proceed under stricter restrictions than those imposed generally in the proposed zoning district. Nothing in this chapter shall be construed as relieving the property which is subject to development agreement restrictions from further compliance with all other permit and code requirements applicable because of the zoning designation of the property. Restrictions imposed upon property as a result of a development agreement are in addition to all other requirements of this title. (1984 Code § 5-9-1)
