Crestmoor, 300 Piedmont Avenue

Crestmoor Conceptual Plan 3-9-2022



Project Description

The Planning Division recently received materials requesting preliminary application review for the former Crestmoor High School site located at 300 Piedmont Avenue (project). The approximately 40.2-acre site is owned by the San Mateo Union High School District and formerly housed Crestmoor High School and subsequently Peninsula Alternative High School.  


The project proposes to demolish the existing structures, athletic facilities, parking, and other improvements to build a new 156-lot single family detached home development of new two-story houses.  The project also proposes to dedicate to the City of San Bruno 12 acres of open space land with the intent that the City may construct new recreational amenities.  The project includes an additional 8 acres of additional open space area which will be accessible to project residents and guests.  It is anticipated that the project may require a Vesting Tentative Map and Planned Unit Permit in addition to CEQA environmental review and may also require additional planning approvals and permits.  The applicant is seeking to take advantage of the State Density Bonus Program to receive waivers and/or incentives/concessions related to open space and lot size requirements.  Of the 156 homes, 132 are proposed to be market rate and 24 (15%) are proposed to be on-site below market units: 8 (5%) affordable to Low-income households and 16 (10%) affordable to Moderate-income households.
