Emergency Preparedness

Emergency Prepardness Mill Valley Fire Truck


Mill Valley is a wonderful place to live and visit, with its stunning vistas and tree-studded canyons backing up to acres of parklands. It’s also a place where being prepared, particularly for residents and visitors, is as important as enjoying the natural beauty.

The City of Mill Valley provides helpful emergency preparedness information for residents and visitors, including what to do in case of an earthquake, fire or flood. It also offers free emergency preparedness classes for Mill Valley residents.

The City’s Emergency Preparedness Commission advocates the need for ongoing emergency preparedness and helps identify, organize and liaison with neighborhoods, businesses, and schools. They assist with educating residents on ways to be self-sufficient in a disaster and encourage CERT training. Meetings are the second Thursday of every month at City Hall.

Safety Tips

Whether you’re here for a day or a lifetime, following are some quick safety tips to help you enjoy your stay:

Staying safe means staying informed.

Sign up for alerts! Alert Marin allows you to receive emergency alerts from the County of Marin via call, text, or email.

Alert Marin alerts provide guidance when action is needed at a specific address or neighborhood, including information about imminent flooding, wildfires, evacuations, and public safety incidents when lives may be at risk.

Nixle – To receive informational real-time alerts and advisories from the Mill Valley Police Department and other local agencies, text the zip code(s) of where you live, work, and learn to 888-777. Nixle alerts provide information about road closures and police activity, general public safety information, and post-disaster information about shelters, transportation, and supplies.

The City of Mill Valley has also crafted emergency preparedness guides tailored for two key groups. These guides focus on potential disasters that business and organization leaders and their teams might face during working hours. They offer practical advice on preparing for and staying safe in various emergency situations.

811 know what's below - call before you dig

Each year serves as a good reminder to everyone to call 811 a few days before digging to identify the approximate location of underground utility lines.

Every six minutes an underground utility line is damaged because someone decided to dig without first calling 811, and we at Mill Valley Chamber of Commerce do not want anyone to become part of the statistic.

Utility services that your family depends on, such as cable TV, high-speed Internet, landline telephone, electric, gas, water and sewer, are buried underground in many communities. Striking one of these lines can result in inconvenient outages for entire neighborhoods, harm to yourself or someone else, and repair costs.

When you call 811 a few days before you plan to start your project, a local one-call center representative will collect your information and notify the affected local utility companies of your intent to dig. A professional locator will then visit the dig site to mark the approximate location of all underground utility lines with paint, flags or both. Once your site has been marked, it is safe to begin digging around the marked areas.

No matter the type of project – installing a mailbox, putting in a fence, planting trees or shrubbery, building a patio or deck, or excavating a new garden area – make sure to call 811 several days prior to digging to have your site properly marked, and remind our customers, as well as your friends and family, to do the same. Always call 811 before you dig and know what’s below.
