Page "Tracy, California" Paragraph 2

Located in the Central Valley, Tracy sits near some fertile agricultural lands and some not so fertile agricultural lands ( because of the hilly region west of Tracy ), some of which ( in the east and mostly north of Tracy because of the moist Delta river system ) has come under increasing development pressure as the San Francisco Bay Area's vigorous population growth has spilled over into the Tracy area as well as other locations such as new town of Mountain House ( because of TRAQC's Measure A in 1990 ) near the Bay Area's edge.
