River Oaks is located in a naturally wooded area defined by the meandering course of the West Fork of the Trinity River, just downstream from Lake Worth. The name of the city celebrates these natural features of the landscape by reminding residents of the many mature oaks trees throughout the City and the close proximity of the Trinity River corridor and the recreational amenities of Lake Worth. The City of River Oaks is approximately 1.9 square miles in area on the west side of the Dallas-Fort Worth Metroplex in North Central Texas. River Oaks is a suburban city, but it is located within the five-mile radius loop defined by Interstate Loop 820 around Fort Worth, in Tarrant County, Texas. The city limits are set, since there is no extra territorial jurisdiction or unincorporated territory for expansion of the city limits.
