The purpose of this chapter is to help protect the health, safety, and general welfare of people in the vicinity of the Sacramento Executive Airport and to improve air navigation safety. More specifically, this chapter is intended to provide for the sensible growth and maintenance of the airport environs, and to effectuate the policies reflected in the Airport Land Use Commission Law in California Public Utilities Code section 21670 et seq., and the Executive Airport Comprehensive Land Use Plan ("CLUP") as revised by the Airport Land Use Commission in May 1998 and May 1999. Some existing development in the area surrounding the Sacramento Executive Airport is inconsistent with the compatibility guidelines set forth in the CLUP and in this chapter. The CLUP and this chapter are primarily directed at preventing new problems of land use incompatibility, rather than removing existing incompatible uses. Existing incompatible land uses may continue notwithstanding other requirements of this chapter. However, with the exception of those uses identified in section 17.312.100, no incompatible land use may be expanded or changed to another incompatible land use.
