Final concrete pours close out a loud week at the middle school

Crews at the Mill Valley Middle School construction site ran early-morning concrete pours from about 3 to 9 a.m. each day between September 22 and 25, the latest stretch of overnight work tied to the ongoing school rebuild. A 24/7 hotline stayed open all week for residents bothered by the noise.

By Friday the city had one more round to announce: a final concrete pour set for September 29, again running roughly 3 to 9 a.m. The city's alert framed it as the last of this batch, a small signal that this phase of construction is winding down even as the rest of the project continues.

No timeline has been given for when pours of this kind might resume, but the hotline remains available for residents with questions.

City readies residents for citywide evacuation drill

The City will hold a community-wide evacuation drill on Saturday, October 3, giving residents a chance to rehearse their emergency plans and letting fire, police and other public safety agencies test how quickly Mill Valley can get people out. The city repeated the announcement in back-to-back alerts this week, a sign officials want it firmly on residents' calendars before autumn fire season fully sets in.

Separately, Caltrans and the Transportation Authority of Marin shared updates this week on planned work at the State Route 131 and Tiburon/East Blithedale interchange — a junction that matters to anyone plotting a route out of town in an emergency, though the city's alert gave no construction timeline.
