INITIAL STUDY/NEGATIVE DECLARATION ER-2004-136 GENERAL PLAN AMENDMENTS TO AIRPORT ENVIRONS ELEMENT, NOISE ELEMENT, LAND USE ELEMENT PROJECT DESCRIPTION Update the City of Santa Ana Airport Environs Element of the General Plan, which establishes a long-range policy guide to safeguard the general welfare of inhabitants within the vicinity of the John Wayne Airport. Additionally, the Noise and Land Use Elements would be amended to achieve internal consistency between City General Plan Elements. Airport Environs Element The purpose of the Airport Environs Element is to ensure that people in facilities are not concentrated in areas susceptible to aircraft accidents and to ensure that no structures or activities adversely affect navigable airspace. The Airport Environs Element establishes land use/noise compatibility criteria, height restrictions and procedures to ensure that proposed development projects are in compliance with the Airport Environs Land Use Plan for John Wayne Airport. The proposed amendment to the Airport Environs Element involves the establishment goals and policies to protect sensitive land uses from airport related noise impacts, to protect the safety of the general public from aircraft hazards and to minimize the impacts of heliports/helistops on the community. Noise Element The City of Santa Ana Noise Element establishes interior and exterior noise level standards for land uses in the City. However, the noise level standards are currently inconsistent with the noise standards established in the Airport Environs Plan for John Wayne Airport. As part of the proposed project, the exterior and interior noise standards in the Noise Element would be amended to provide consistency with other City General Plan Elements. Table 1 identifies the noise standards in the current Noise Element, and Table 2 reflects the proposed noise standards in the amended Noise Element 1 F75~T ~9
