The Menlo Park City School District is considering changing the grade configurations and attendance areas of its elementary schools to deal with anticipated enrollment growth through 2015.

The public is invited to a special board meeting at 7 p.m. Wednesday, Sept. 27, to hear and comment on initial reports on this topic. The meeting will be in the Encinal School multi-use room, 195 Encinal Ave. in Atherton.

Voters approved in June a $91 million bond measure to expand and update the district’s schools.

Before developing facility projects, the district needs to determine the grade levels and enrollment size of each elementary school, said Superintendent Ken Ranella.

“It is evident, given the size and capacities of our schools, that Encinal, our largest campus, must substantially grow in enrollment, and Oak Knoll and Laurel schools must be structured to decline,” he said.

During the meeting, the superintendent will present initial studies, and options for reconfiguring Laurel, Encinal and Oak Knoll schools. Community members will have an opportunity to comment during a public hearing.

Topics for further study may be identified by the board and discussed at its special meeting Wednesday, October 25.
