Each semester, more than 12,000 individuals of all ages, ethnicities and backgrounds attend Miramar College classes to obtain associate degrees, the first two years of university transfer courses, or train for a career. Miramar College opened as a training facility for San Diego's law enforcement personnel and firefighters in 1969. While the College is still home to the San Diego Regional Public Safety Institute, it has grown into a comprehensive community college, offering transfer and expanded career training programs, including biotechnology, advanced transportation, paralegal, child development, business and more. Locally passed facilities bond measures in 2002 and 2006 have resulted in the recent transformation of the 125-acre campus. New facilities include math & business and arts & humanities classroom buildings, renovation and expansion of the advanced transportation/automotive, aviation and diesel technology buildings, completion of the Hourglass Field athletics complex, a multi-level parking structure and police sub-station, campus-wide infrastructure improvements, and a massive 100,000 square foot Library Learning Resource Center. A cafeteria/bookstore/student services center, fire technology, administration and science expansion are currently, or soon to be, in construction. All facilities meet LEED certification; the police substation earning Platinum LEED, the highest possible recognition for energy efficient design and the first in the San Diego Community College District to achieve Platinum certification. In the fall of 2012, the college became a smoke-free campus.
