Updated Noise Contours Exhibits
Reflect noise contours identified by 2014 JWA Airport Settlement Agreement Amendment
EIR #617
•Proposed noise contours are based on more contemporary aviation operations;
•Quieter fleet of existing commercial aircraft & reduction in number of generation aviation operations; and
•Based on newer state-of-art in airport noise modeling
Resulting more up-to-date noise contours

F. Residential Use Proximate to John Wayne Airport Environs Land Use Plan. Residential uses, including mixed-use
residential, shall be prohibited within the 1985 John Wayne Airport (JWA) Master Plan 65 dBA CNEL contour allowed on parcels or
sites wholly or partially outside the John Wayne Airport 65 dBA CNEL noise contour as shown in Figure N5 of the Noise Element of
the General Plan, as identified in the 2014 John Wayne Airport Settlement Agreement Amendment Environmental Impact Report (EIR
No. 617) and consistent with Title 21 of the California Code of Regulations, subject to the following conditions that apply to all
residential projects within the John Wayne Airport 60 dBA CNEL or higher CNEL noise as shown in Figures N4 and N5 of the Noise
Element of the General Plan:
1) Prior to the issuance of any building permits for such development, a noise study shall be prepared by a City-approved
qualified acoustical consultant and submitted to the Community Development Director for approval;
2) All new residential structures or the residential units within a mixed-use development shall be attenuated to provide an
interior noise level of 45 dBA CNEL or less;
3) The design of the residential portions of mixed-use projects and residential developments shall have adequate noise
attenuation between adjacent uses and units (common floor/ceilings) in accordance with the California Building Code;
4) New mixed-use developments shall incorporate designs with loading areas, parking lots, driveways, trash enclosures,
mechanical equipment, and other noise sources away from the residential portion of the development;
5) Use of walls, berms, interior noise insulation, double paned windows, advance insulation systems, or other noise
mitigation measures, as deemed appropriate shall be incorporated in the design of new residential to bring interior sound
attenuation to 45 dBA CNEL or less;
6) Residential uses shall be indoor-oriented to reduce noise impingement on outdoor living areas;
7) On-site indoor amenities, such as fitness facilities or recreation and entertainment facilities shall be encouraged; and
8) Advanced air filtration systems for buildings shall be considered to promote cleaner air.
Residential development shall be limited to parcels or sites wholly or partially outside the 65 dBA CNEL noise contour, unless and
until the City determines, based on substantial evidence, that the parcels or sites wholly within such contour area are needed for the
City to satisfy its Sixth Cycle RHNA mandate. Non-residential uses are encouraged on parcels or sites located wholly within the 65
dBA CNEL contour area.
