In June 1950, a federal judge ordered the Euless School District to provide a separate school for African American children. To comply, the district temporarily re-opened Mosier Valley School. By September 1951, classes were moved into a new brick building. In 1984, a historical marker was dedicated at the original location of the school. The original wooden school house was moved to Bedford in May 1984. Combined districts The Euless and Hurst school districts merged in 1955. The combined district served 1,418 students and grew to almost 2,300 students in the next two years. In 1955, Lawrence D. Bell High School also known as L.D. Bell was founded. In 1958, the residents of the Bedford School District voted to merge with the Hurst-Euless School District by 212 to 189. (Similar attempts to combine the cities themselves have not succeeded.) The tri-city district served 3,116 students during its first year, including 68 high school seniors, at seven schools: Bell High School (at the current site of Central Junior High) Bedford Elementary (the afore-mentioned Bedford School, now City of Bedford property) South Hurst (no longer district property) North Hurst (now Hurst Junior High) Mosier Valley Elementary (now a community building) Euless Elementary (now South Euless Elementary) West Elementary (now West Hurst Elementary). Later that school year, North Euless Elementary opened and Pennington Field was completed. The next decade brought Oakwood Terrace Elementary (1962) Wilshire Elementary (1964), the current L.D. Bell High School campus (1965), Donna Park Elementary (1966), Midway Park Elementary (1967), Bell's Driver's Education Facility (1968), and in 1969 Trinity High School, Bell Manor Elementary and Hurst Hills Elementary. Racial integration began in the summer of 1965 in a Head Start class. HEB ISD desegregated in 1968. Events since 1997 In 1997, voters approved a municipal bond of $170 million, the largest bond package that the district had ever proposed. The package included nearly $50 million for technology alone, allowed major renovations at nearly all campuses, and funded the construction of the Pat May Center administration building. The District called River Trails Elementary (opened August 2002) a "bonus" from the bond; the school's $7.5 million construction was paid for entirely by interest and investment of the bond fund. HEB ISD's grade configuration of elementary (K-6), junior high (7-9), and high school (10-12) differs from the most common alignment among school districts in Texas (K-5, 6-8, 9-12). In September 2006, a task
