Located in the Greater Bay Area, Tracy is near both fertile and (due to a region of hills west of Tracy) infertile agricultural lands. Tracy has a Mediterranean climate.
Some of this land (in the east and mostly north of Tracy because of the moist Delta river system) has come under increasing development pressure. The San Francisco Bay Area‘s vigorous population growth has spilled over into the Tracy area as well as other locations, such as the new town of Mountain House. Tracy passed Measure A in 1990 to try to contain and limit development.
In an effort to reduce the environmental impacts of the city, it launched the Emerald Tracy Project in September 2009. City spokesman Matt Robinson said that if it succeeds, Tracy will be the second city after Riverside, California to satisfy the state’s goal for sustainable communities.
