Sports Complex, including the football stadium, a baseball field, a softball field, six tennis courts, a track which encircles a field for track and field, soccer, and lacrosse, and multiple practice fields. Adjacent to the complex is the Cub Run RECenter, home to Westfield's swim and dive team, although it is not part of the school. Overcrowding In the mid-2000s, Westfield was often criticized as grossly overcrowded. The building design provided for a capacity of 2,500 students, a number that was reached in its third year of opening. When the school opened, the unincorporated communities of Centreville and Chantilly experienced a population and real estate boom that was not projected by the county. By the 2004–2005 academic year, the school was over its capacity by 25 percent, and 26 trailers filled the parking lot originally designated for faculty and staff along with additional ground space surrounding the school's main building. In April 2003, FCPS proposed a bond referendum for the construction of a 124-room addition to Westfield's main building to alleviate the rapid growth of the student population. The bond referendum provided for the construction of the new addition at a cost of $8.7 million. The bond was approved in November of the same year, and construction for the massive new wing began in summer of 2005. Construction was completed in time for the 2006–2007 school year, increasing capacity to 3,100. It has two levels and a basement. It is called the R-hallway. Some former feeder communities of Westfield were re-zoned to the attendance boundary of South Lakes High School, located in the unincorporated community of Reston. Due to this boundary adjustment Westfield's enrollment has declined and is currently considered under capacity with a 2013–2014 student membership of 2,750. Community use Northern Virginia's New Life Christian Church held services at Westfield after relocating its main campus from Stone Middle School before building and moving to the Zone. Three services are held each Sunday with an attendance of 1,500. In 2003, the Work Awareness and Transition (WAT) class opened a branch of the Apple Federal Credit Union for students and faculty. The branch is operated by student tellers in WAT. Hope Chinese School, a Chinese language school in the Washington area, designated Westfield as the site of its Chantilly campus in fall 2006. Chinese language and cultural elective classes are held on Sunday afternoons in the new building addition. The local
