If she returns the papers and becomes qualified for election, Ms. Uribe-Ruiz will join incumbent Laura Linkletter Rich, former board member Terry Thygesen, and community volunteer Joan Lambert in a contest for three seats on the five-member board.
Three seats are also open for the board of the Las Lomitas Elementary School District, which covers western parts of Menlo Park and Atherton as well as Ladera and other unincorporated communities.
In this district, two candidates have filed papers and one has not yet done so. The filers are incumbent Jay Siegel and Richard Ginn, a managing director and the chief financial officer of Costella Kirsch, a venture capital firm in West Menlo Park.
Ann C. Jaquith, who described herself as an educator, took out papers but has not yet filed them, according to registrar records.
