The Mill Valley School District  Board of Trustees will vote on the Mill Valley Middle School Modernization Project at its December, 15, 2025 meeting. After extensive planning and environmental review, the Superintendent recommends renovating the existing campus at 425 Sycamore Avenue with students remaining on-site in temporary portable classrooms during construction.

✓ Safe – Environmental Impact Review and Preliminary Endangerment Assessment confirm the campus is safe with proper mitigation and monitoring

✓ Fiscally Responsible – Stays within the $130M budget; avoids $23.6M in soil costs and up to $2.5M annually in transportation

✓ Environmentally Superior – Reduces construction impacts compared to full reconstruction

✓ Keeps Students Together – All grades 6-8 stay on the 14-acre Sycamore campus

✓ Protects Elementary Schools – No displacement of Edna Maguire students or community programs

✓ Community Supported – Aligns with public input received during the review process

The California Department of Toxic Substances Control (DTSC) has accepted the Preliminary Endangerment Assessment with no revisions required. The review found no increased risk to students or staff under current school use. As anticipated, DTSC has requested some additional testing and development of a Mitigation Plan to ensure long-term protection. Should the project be approved, installation of a sub-slab vapor barrier system is planned to protect indoor air quality.

The modernization (funded by Measure G bond) includes:
