Las Lomitas Elementary School District underwent a major expansion of their two existing school campuses. Designs include the addition of two new two-story structural steel braced frame buildings (34,0000 sf and 9,300 sf) along with four single story wood-framed classroom/administration buildings ranging in size from 2,400 sf to 4,800 sq. ft. The design incorporates sloping roofs with exposed structural steel roof beams with an open two-story atrium and second floor corridor. The single story buildings have wood soffit roof overhangs and architecturally exposed structural glulam beams inside the classrooms. To help mitigate flooding at the elementary school from a nearby creek, the administration building integrates the design of box culverts beneath the building to capture flood water from the front parking lot and carry it beneath the campus to the rear playfields where it can reenter the creek.
