Eastvale was one of several unincorporated areas of Riverside County that had strong community support for city incorporation. The passage of AB 1602 in the mid-2000s, a state bill that adds funds from vehicle license fees, made it easier for unincorporated areas to attain cityhood. In 2008, the communities of Menifee, Sun City and Quail Valley merged and incorporated as the City of Menifee. The law also brought renewed interest in incorporation efforts for Mira Loma and Jurupa Valley (Mira Loma, Pedley, Glen Avon, Sunnyslope, and Rubidoux).
