Draft EA - San Diego International Airport

SAN DIEGO INTERNATIONAL AIRPORT – PROPOSED RUNWAY 9 DISPLACED THRESHOLD
Noise exposure maps (NEMs) were developed for SDIA as part of the Part 150 Update Study completed in
2009. 14 The CNEL 65 dB noise contour for 2009 is shown on Figure 3-2.
3.4 Demographics and Socioeconomic Profile
Socioeconomics are the activities and resources associated with the everyday human environment, particularly
with population centers, their demographics, and economic activities generated. Executive Order 12898,
Federal Actions to Address Environmental Justice in Minority Populations and Low-Income Populations, was
enacted in 1994 to ensure the fair treatment and meaningful involvement of all people regardless of race,
color, national origin, or income with respect to the development, implementation, and enforcement of
environmental laws, regulations, and policies. Fair treatment means that no groups of people, including racial,
ethnic, or socioeconomic groups, should bear a disproportionate share of the negative environmental
consequences resulting from industrial, municipal, and commercial operations or the execution of federal,
state, tribal, and local programs and policies. Consideration of environmental justice concerns must be given
to populations in the vicinity of a proposed project.
A series of census tracts in the immediate vicinity of the Airport have been identified for socioeconomic
analysis. Figure 3-3 depicts these census tracts in relation to the Airport property. The tables that follow give
detailed information on the communities surrounding the Airport. The indirect Study Area described in
Section 3.1, includes at least portions of the following census tracts: 100, 202, 5800, 5900, 6000, 6100, 6200,
6300, 6500, 6900, and 21400.
The Study Area has a population that is predominantly Caucasian (82 percent), with Asians making up the next
highest ethnic group at 4 percent (see Table 3-1). The Study Area is largely an affluent population, except for
census tract 6500 which has a median household income of $32,721 (see Table 3-2). The remaining census
tracts have median incomes that range from $52,107 to $112,065. Tracts 6200 and 6300, Airport and U.S.
Marine Corps lands, do not report median incomes or poverty levels.
