The Mill Valley School District has changed its middle school environmental impact report, shifting from a full replacement to a renovation plan. At a May 14 meeting, trustees approved the addendum, which cuts back on demolition and soil movement and updates mitigation to fit a renovation.
This revision aims to protect students, staff, and neighbors. The project will move forward with interim classrooms set up on site during construction.

Renovation, Not Replacement: A Change in Scope for Mill Valley Middle School
I’ve watched Marin County schools shift gears before, and it’s always a bit of a rollercoaster. Here, the Mill Valley Middle School project now calls for much less demolition and excavation than the original replacement plan.
The district’s 48-page addendum, prepared by Grassetti Environmental Consulting, updates mitigation measures to reflect the smaller scope. Working on a site that used to be a city landfill and burn dump? That’s no small challenge.
The district wants a safe, transparent process that meets the requirements of the California Department of Toxic Substances Control (DTSC) and Marin County Environmental Health. They’re also aiming for open communication with regulators and the Marin community.
In Marin towns like Fairfax, Larkspur, and San Anselmo, parents want to know how construction will play out and how risks will be handled. Moving soil, installing vapor barriers, and monitoring methane are all part of the conversation.
Key Revisions to the Environmental Impact Report
The new plan comes with several updated or added mitigation measures. It’s not just paperwork; these changes address what’s actually doable and the lighter environmental footprint of renovation.
The district tweaked plans for construction noise, dust control, and air filtration to better fit the realities of a busy Marin neighborhood.
- Less demolition, excavation, and soil movement than the original plan.
- Mitigation measures updated for feasibility and reduced impacts.
- Better plans for noise management, dust suppression, and filtration.
- Interim classrooms set up on campus during construction, starting in June, with main construction kicking off in January.
- Vapor barriers installed under the building and continuous methane monitoring, since the site used to be a landfill.
- Contractors must follow DTSC land-use covenants, working alongside DTSC, state regulators, and Marin County Environmental Health.
People in Mill Valley, San Rafael, and Corte Madera want real assurance that toxins will be handled and remediation will be practical. The district says it’ll work with DTSC and other regulators on a thorough mitigation plan and stay under the watch of several agencies, including Marin County Environmental Health.
Health, Safety and On-Site Protections for the Marin Community
Protecting the health and safety of students, staff, and neighbors is still the district’s top priority. Construction will include health-focused safeguards, especially since the site is close to schools and neighborhoods in places like Sausalito, Tiburon, and Ross.
Construction Safeguards and Environmental Health
District officials say they’ll keep working with state and local regulators to ensure safe operations. They’re planning continuous methane monitoring, vapor barriers, strong dust controls, and better air filtration.
Collaboration with the DTSC and Marin County Environmental Health will provide ongoing oversight and transparent reporting as work moves ahead on the Mill Valley campus.
Funding, Timeline and Oversight: How This Project Is Paying For It
The renovation’s estimated cost is about $95 million, funded by the district’s Measure G bond program. Measure G, approved by voters in 2022, set aside $194 million for district projects, including upgrades to elementary schools across Marin County.
The district will use Measure G dollars for the middle school renovation, with ongoing oversight from the state DTSC and Marin County Environmental Health. This should help ensure the money is spent with environmental safeguards in mind.
Budget, Bonds and Local Oversight
The addendum says the district will keep coordinating with the California Department of Toxic Substances Control and Marin County Environmental Health through the entire project. For families in Mill Valley, Corte Madera, Larkspur, and nearby areas, this oversight matters—they want to know that soil and air quality will be protected as classrooms get their much-needed updates.
What This Means for Marin County Communities
For folks in Mill Valley and nearby towns, this shift from replacement to renovation shows a cautious mindset that puts safety and stewardship first. Local families who know the waterfront charm of Sausalito or the hills around San Anselmo can expect changes to move at a pace that respects the land’s quirks and the site’s landfill-era roots.
The price tag isn’t small, but this renovation fits right in with Marin County’s bigger push—upgrading old buildings with a focus on the environment and open, honest decision-making.
I’ll keep an eye on the construction schedule, any regulatory twists, and what residents are saying from Mill Valley to Fairfax. Schools here aren’t just places to learn—they’re the heart of the community.
Let’s see where the Mill Valley Middle School renovation takes us and what it’ll mean for families all over the peninsula. Honestly, it’s hard not to feel a little curious about what’s next.
