Castilleja School

Rendering of proposed Castilleja School plans

Castilleja School, 1310 Bryant Street, Palo Alto

Castilleja is a private, all-girls’ school for 6th through 12th grades, located at 1310 Bryant Street at Embarcadero Road in Palo Alto. The school has been at the current site, which is zoned Residential -- Single Family Residential (R-1) 10,000, since 1907, and is surrounded by single family homes.

In the year 2000, Castilleja received a use permit from the City of Palo Alto for an enrollment of 415 students. 13 years later, the City discovered that Castilleja’s enrollment exceeded this allowance and initiated code enforcement actions including a significant financial penalty, a requirement that the school begin to reduce its enrolment, and a requirement that the school apply for a new use permit to request any increase above the permitted amount.


Pending Application

For the 2018-2019 school year, Castilleja informed City staff that student enrollment is 434 students. On June 30, 2016, the school submitted requests for a new conditional use permit to increase student enrollment and to allow for phased redevelopment of their campus, including construction of an underground parking structure in phase one. The use permit application seeks approval to increase the total number of students over a 4-5 year period, with the addition of no more than 27 students per year. The application (File# 16PLN-00238) and other materials provided by the applicant can be accessed to the right of this page.


News Update-April 21, 2020

Castilleja School submitted an updated Alternative Project plan in mid-April 2020. The Alternative plans are viewable on Building Eye ( under the address 1310 Bryant, file number 19PLN-00116. Preparation of the Final EIR is underway.


  • Project Alternative plans- updated Project Alternative plans (which supersede the February 2020 Project Alternative plans and also retain two homes on Emerson) are associated with the EIR. These updated plans show a further reduction of the subterranean garage footprint, enabling tree retention and other adjustments. The dispersed drop-offs plan includes retention of the drop-off driveway at Kellogg, with associated pull-back/reduction of new building's above grade building footprint. In the event the Project Alternative is deemed the environmentally superior project and ultimately approved, two applications associated with the Project would become unnecessary:(1) the setback Variance request (a component in file 16PLN-00238), and (2) the 2017 Tentative Map with Exceptions application (17PLN-00234). 
  • The third round ARB-Project Plans dated 2/10/20 addressed City comments regarding 'incompleteness'; the set and the ARB application were deemed complete March 10, 2020.
