Castilleja School 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 School 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.
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.
