The Fort Yuma Reservation of the Quechan Tribe is located on 9,246 acres in the southwest corner of California in Imperial County and the southeast corner of Arizona in Yuma County. Historical records indicate the Quechans have inhabited the area since approximately 800 A.D. The 1974 tribal rolls show a population of 1,687. The unemployment rate is 52 percent with underemployment also a severe problem with 39 percent of those employed earning less than $5000 annually. Adequate housing is a major concern as only 632.7 acres are in tribal ownership and some tribal members have difficulty securing permanent housing sites. The use of agricultural land for homes would diminish that economic potential for the reservation. Development of a subdivision might be one solution to alleviate housing needs. Areas of potential economic development include agriculture, tourism, and a motel-restaurant complex. Job availabilities are centered primarily in surrounding cities and employment education should be a major element in tribal programs to eliminate unemployment and underemployment. In addition to making planning recommendations for tribal action, the document provides socioeconomic analysis, history, and goals of the Quechan people, and discusses their land resources, housing status, physical systems, human resources, and planning alternatives.
