Exhibit "A"
COMMUNITY NOISE ENVIRONMENTS MAP
The Community Noise Environments Map is to be used with the Land
Use Compatibility Chart and the related interpretive description
to guide noise compatible land use planning in Alameda. The
Chart indicates the range of acceptability of various types of
land use in relation to levels of noise exposure. The map shows
those areas in the City that are Normally Acceptable, Conditionally
Acceptable, Normally Unacceptable, and Clearly Unacceptable for
noise-sensitive land uses. The noise sensitive uses are residential
(including transient lodging), schools, libraries, churches,
hospitals and nursing homes. Although the map is oriented to noise-
sensitive land uses, it also should be used to determine compatible
noise environments for the other land uses listed in the Chart.
The Community Noise Environment Map shall also be used to determine
High Exposure Areas for application of Ordinance No. 1750 N.S., the
City of Alameda's Noise Insulation Ordinance. High Exposure Areas
are areas where the total community noise equivalent level (the
CNEL of all sources) attains or exceeds 65 dB.
The community noise environments, delineated on the map, represent
a composite of CNELs from all sources. Surface noise and Naval Air
Station noise were taken from the M.A.G. maps. Oakland Airport
noise levels are based on the Wyle Case C except that the 70 dB
contour closest to Runway 29 was adjusted to follow the general
alignment of Catalina Avenue 1 and the 65 dB contour was adjusted
to follow a segment of Mecartney Road to the end of present
development. 2
1 See Discussion of Title 4, pp. 34-35.
2 This adjustment was desirable to remove the curvature, which in
addition to the map distortions would make the line difficult
to locate on the ground. A definite location was picked on
Mecartney Road which would retain the integrity of uses in the
immediate vicinity of the line along Mecartney.

APPLICATION OF INTERIOR STANDARDS
Noise attenuation standards to be used in the design of improve-
ments in the area zoned commercial-manufacturing and subject to
noise easements are as follows:
A. The interior noise levels in all habitable rooms attributable
to exterior noise sources shall not exceed the maximum interior
noise levels specified in the Allowable Maximum Interior Noise
Level Chart shown on pages 88a, 88b and 88c.
B. The reduction from an exterior noise level to an interior
noise level in each room of each commercial and manufacturing
structure shall comply with the values set forth in the Allow-
able Maximum Interior Noise Level. Chart for each of the follow-
ing three bands of land:
1.. That portion of the noise easement area zoned commercial-
manufacturing that is situated north (t at is, on the
and Side") of the "70 dB CNEL contour" relocated to the
Wyle Case C line (hereinafter, "relocated 70 dB CNEL contour").
2. That portion of the noise easement area zoned commercial-
manufacturing that is situated south (that: is, on the "Bay
Side") of the "relocated 70 dB CNEL contour" and north
(that is, on the "Land Side") of the "75 dB CNEL contour"
appearing in the Noise Element of the City of Alameda (1975)
3. That portion of the noise easement ,area zoned commercial-
manufacturing that is situated south (that is, on the "Bay
Side") of the "75 dB CNEL contour" appearing in the Noise
Element of the City of Alameda (1975).

COMMUNITY NOISE ENVIRONMENTS MAP
The Community Noise Environments Map is to be used with the Land
Use Compatibility Chart and the related interpretive description
and the noise attentuation design standards and the Allowable
Maximum Interior Noise Level Chart for land uses zoned commercial-
manufacturing on Bay Farm Island to guide noise compatible land use
planning in Alameda. The Chart indicates the range of acceptability'
of various types of land use in relation to levels of noise exposure,
The map shows those areas in the City that are Normally Acceptable,
Conditionally Acceptable, Normally Unacceptable, and Clearly Un-
acceptable for noise-sensitive land uses. The noise sensitive uses
are residential (including transient lodging), schools, libraries,
churches, hospitals and nursing homes. Although the map is
oriented to noise-sensitive land use, it also should be used to
determine compatible noise environments for the other land uses
listed in the Land Use Compatibility Chart and the Allowable
Maximum interior Noise Level Chart for land uses zoned commerciae-
manufacturing on Bay Farm Island
The Community Noise Environment Map shall also be used to determine
High. Exposure P.reas for application of Ordinance No. 1750 N.S., the
City. of Alameda's Noise Insulation Ordinance. High Exposure Area
are areas where the total community noise equivalent level (the
CNEL of all sources) attains or exceeds 65 dB.
The community noise environments, delineated on the map, represent
a composite of CNELs from all sources. Surface noise and Naval

Air Station noise were taken from the M.A.G. maps. Oakland Air-
port noise levels are based on the Wyle Case C except that the
70 dB-contour closest to Runway 29 was adjusted to follow the
general alignment of Calalina Avenuel / and the 65 dB contour was
adjusted to follow a segment of Mecartney Road to the end of
present development.2- / Evidence presented in 1980 supports the
relocation of the 70 dB CNEL line from its adjusted alignment along
Catalina Avenue to its alignment to the Wyle Case C Report.
1/ See Discussion of Title 4, pp. 34-35.
2/ This adjustment was desirable to remove the curvature, which in
addition to the map distortions would make the line difficult
to locate on the ground. A definite location was picked on
Mecartney Road which would retain the integrity of uses-in the
immediate vicinity of the line along Mecartney.
