[caption id="attachment_449811" align="alignnone" width="1058"]Coppell and Irving demographics Coppell and Irving are geographically wedged in Dallas County’s northeastern corner. While Las Colinas and Valley Ranch are located within the city of Irving, different portions of the two communities are zoned for Coppell ISD, Irving ISD and Carrollton-Farmers Branch ISD schools. The area also surrounds a portion of the city of Dallas.[/caption] Correction: A previous version of this graphic said Irving ISD has eight high schools. In fact, it has five high schools.
