General Plan Update - City of Inglewood

Chapter 6 Community Safety and Hazards
Major streets in the City of Inglewood include Inglewood, Centinela, Florence,
Manchester, La Brea, and Prairie Avenues and Century and Crenshaw Boulevards.
Residential uses near arterial roadways may experience attenuated noise levels from the
presence of any large-scale commercial structures separating the residential area from
those arterials, from yard walls or barriers, and from the distance between the roadway
and the residential structures. The noise attenuation features of new residential uses are
reviewed on a project-by-project basis as part of the City’s development review process.
As new residential projects are proposed near major roadways or other potential noise
sources, future noise levels can be evaluated and noise mitigation strategies required as
appropriate to meet City noise standards.
Aircraft Sources
Land uses within the City of Inglewood are affected by aircraft approaches, and
departures to a lesser extent, at the Los Angeles International Airport (LAX). In addition,
aircraft activity at the Hawthorne Municipal Airport may occasionally affect residential
uses located in the southern portion of the City. The California Division of Aeronautics
has adopted the CNEL as their methodology for describing airport noise exposure and
requires land uses within the 65 dBA CNEL contour around airports to be compatible
with airport operations. Land uses considered incompatible within the 65 dBA CNEL
airport noise contour are single-family and multi-family residences, trailer parks, schools,
hospitals, and childcare facilities.
Stationary Sources
A wide variety of stationary sources that are typical of an urban setting are present in the
City of Inglewood. The City contains many different uses (e.g., commercial, residential,
institutions, public facilities, utilities, etc.), all of which can produce noise. Residential
areas can generate noise through the use of heating and cooling equipment and through
landscape maintenance equipment such as gasoline-powered lawnmowers. Commercial
uses can generate noise through the operation of rooftop heating and cooling equipment,
and other operational activities such as trash deposit and collection, noise emanating
from within businesses, and deliveries. Outdoor sports facilities that attract large numbers
of spectators, such as Hollywood Park, can produce noise that affects nearby receptors.
Existing Noise Levels
Monitored Locations
Existing ambient daytime noise levels were measured at 11 locations within the City of
Inglewood on March 1, 2006. The selected locations are representative of typical land
uses within the City. The purpose of the noise measurements was to both characterize
typical ambient noise levels and to identify major noise sources in the City. Noise
measurements were completed at residential neighborhoods, hospitals, a park, a high
school, The Forum, Hollywood Park, and along heavily traveled roadways. The noise
monitoring locations are shown in Figure 6.9-1.
