The Atlas Tract (formerly known as the Hartland Tract)[3] is an island in the Sacramento–San Joaquin River Delta, in San Joaquin County, California. It has been used for agriculture since it was first reclaimed in the late 19th century.
To the north of the Atlas Tract lies the Bishop Tract, from which it is separated by Bear Creek and Pixley Slough.[6][7] To its west and south, across Mosher Slough, is the Shima Tract; to its east is Interstate 5.[6]
History
In the 1880s, the Atlas Tract was first developed and planted by Charles E. Knapp, a real estate investor and employee of the Southern Pacific company.[8] At the time, its largest landowners were Judge Cooney and Dr. S. F. Long, of San Francisco.[8] By 1915, livestock were being raised on the tract by M. Goldstein;[9] in 1935, the tract was still used for ranching and was the location of the Biaga ranch.[10]
In 1967, the First Stockton Corporation proposed to develop a man-made marina and lake there; the Stockton Planning Commission endorsed this proposal, but the county of San Joaquin had delayed approval of excavation permits.[11] The marina and park were to be constructed by removing 4,350,000 cubic yards (3,330,000 m3) of material, to be used for nearby freeway construction.[3] In December, it was announced that county officials had approved the plan, which was expected to be completed around 1970.[12] However, no such developments are shown in topographic maps from 1978,[13] 1993,[14] 1997,[6] or 2015.[15] In 2006, the Atlas Tract was aerially sprayed to kill mosquitoes suspected of carrying the West Nile virus.[16]
As of 2017, the Atlas Tract was owned by the Alex and Faye Spanos Family Trust, and used solely for agriculture (being used to grow small grains and hay).[2]: 325, 340 At that time, there were no residences on the land, but a large-scale residential development had been proposed on the tract (with potentially as many as 1,400 lots).[2]: 402 In 2015, the population was 0; the San Joaquin County Local Agency Formation Commission projected a population of 42,000 by 2045.[2]: 340
