Northeast El Paso is part of the city of El Paso, Texas and is located north of Central El Paso, and east of the Franklin Mountains.  Its southern boundary is variously given as Fred Wilson Boulevard or Cassidy Road and Van Buren Avenue, and it extends northward to the New Mexico state line; some portions of this region lie outside the city limits, including parts of Franklin Mountains State Park and areas of Fort Bliss: the Logan area of Fort Bliss around Chapin High School and Castner Range, an old firing range northwest of Hondo Pass Avenue and Gateway South Boulevard.  Development of Northeast El Paso, which had begun before the Second World War around the Logan area, started in earnest during the 1950s, when many homes were demolished in the process of the construction of Interstate 10.  It is one of the more ethnically diverse areas of town due to a high concentration of enlisted military families.  Northeast El Paso has historically not developed at a rate comparable to East El Paso and Northwest El Paso, but in recent years, it has seen an increase in development.  It is expected that the population in Northeast El Paso will grow more rapidly as a result of the troop increase for Fort Bliss in the coming years.  Northeast El Paso has gained recognition throughout the city for schools like Parkland, Irvin, Andress and Chapin because of their outstanding athletic programs.
