Our Position

Neighbors would like to peacefully co-exist with the school. They have outgrown the small 6-acre parcel. If they truly want to educate more young women they could easily educate hundreds of additional students by splitting the campus or moving to a new location, as Harker School and many other local private schools have done. We would be willing to accept a modest increase in enrollment, but many neighbors are adamant that the school be forced to abide by the current CUP of 415 students. The garage is a non-starter. The plan is flawed. It would direct all traffic into the neighborhood and through a bike boulevard. And it would be a huge step towards even larger enrollment and greater impacts to the neighborhood.

The Issue At-a-Glance

Castilleja is a private school operating in a R1 residential neighborhood under the terms of a conditional use permit (CUP) issued by the City of Palo Alto. The CUP sets the enrollment cap for the school at 415 students. Castilleja has violated the CUP since it was established 17 years ago, with a current enrollment of 438 students. Castilleja clears a profit of $1.2 million per year from the illegal enrollment. They pay no property taxes.

In June 2016, Castilleja unveiled plans to build an underground garage, destroy 2 single family homes, remove mature trees, and increase enrollment by 30% to 540 students, without any input or feedback from neighbors. The proposed garage would require all cars to enter on Bryant, which is a bike boulevard used by students commuting to Jordan, Paly, and Addison, as well as downtown workers and commuters. All cars would be required to exit onto Embarcadero Road heading east, where cars are coming out of the Embarcadero underpass at high speed. Castillleja proposes to take over one lane of Embarcadero during commute times. There would be 5-6 years of construction with thousands of truck runs up and down Embarcadero Road.

Castilleja serves about 100 students from Palo Alto.

The Palo Alto Weekly has highlighted the flawed project design and Castilleja's refusal to work with neighbors in a June editorial >

Castilleja has lied on their project application and in public, stating that they worked with neighbors who "have always insisted" on a garage. 47 individual households within a two block radius of the school have signed statements submitted to the school that they are opposed to the garage.


Neighbors speak out at City Council meetings.

Castilleja shows their true colors by trying to blame the City and residents for delays in their destructive and divisive project.

PA Weekly Editorial
Castilleja's Unwise Stubbornness > is a grassroots organization committed to protecting Palo Alto residents from commercial development in R1 neighborhoods. Castilleja School is a business operating in a R1 zone and should not be allowed to build an underground garage or continue with permit violations that have been ongoing for 17 years. We ask for managed development with true community input.
