The College of Southern Idaho board is considering the most sweeping series of additions on campus since construction of the school began in 1967.

President Gerald Meyerhoeffer is asking the board for a $7 million plant facilities levy to build four new buildings. The levy - $1 million a year for seven years - would increase property taxes in Twin Falls and Jerome counties $13.33 for a $40,000 house with a homeowner's exemption.The additions would accommodate the school's growth, including an average annual enrollment increase of 37 percent in the last five years.

The new buildings would be located adjacent to existing structures.

The proposal includes a 25,000-square-foot expansion to the Shields Building at $2 million; a two-story addition to the Fine Arts Center for $1.75 million; a two-level addition to the Physical Education Building at $1.53 million; and a 25,000-square-foot, $750,000 addition to the Exposition Center.
