County's General Plan for future urban and other land use projections presented in Tables
III.A.4b-l and III.A.4b-2 (49,760 + 12,197 = 61,957 acres).

IILB Population
The current and projected populations in the District's study area were developed from available
data generated by the Imperial Valley Association of Governments (IV AG) and the Imperial
County Planning Department. Population projections must be analyzed to arrive at a reasonable
estimate for projected land use (Chapter III.AAa and b), which in turn is required for establishing
future water requirements.

IILB.l Current Population
The 1994 population of the District study area was estimated at 135,675 by IV AG. The seven
incorporated cities' population within the District accounts for 102,691 of the 135,675 residents
as shown in Table III.B-l. The combined seven cities population increased for the period 1990-
94 by approximately 25 percent while the population of the unincorporated area increased by
approximately 20 percent. The cities with the highest and lowest increases in population for that
same five year time period were Calipatria (69 percent) and Brawley (15 percent) respectively.
The 1995 Imperial Valley population baseline is estimated at 135,700 people.

IILB.2 Future Population
The potential for growth within the Valley is high because of the ready availability of land,
favorable climatic conditions, and proximity to the larger markets of Los Angeles, San Diego and
other cities. The greatest influences on the Valley's population growth are the stability and
expansion of the economic base. The enticement of new industry resulting from NAFT A,
expansion of the two existing state prisons, and the increased development of geothermal
resources in the area may spur permanent population growth by creating additional job
opportunities. Significant increases in the number of job opportunities associated with the
agricultural industry were not considered likely for the preparation of this report, and may even
be reduced by a shift to less labor-intensive crops and farming practices. Another source of
seasonal population that should continue to increase is the winter visitor. Major increases in this
