Zone 1 (City of Sausalito)

Zone 1 (City of Sausalito) is a small coastal town with most of the residential structures built on the hillsides from just above sea level to the top of Wolfback Ridge which reaches up to about 1,120 feet. The wildland urban interface lays approximately within the 450 foot to 1,120 foot elevation line. It consists of close proximity housing with irrigated landscaping punctuated by small jack pots of Eucalyptus stands with deep duff layers, Oak Woodlands with some Sudden Oak Death fuel loading, deep undeveloped canyon areas filled with Bay trees and then large patches of coastal chaparrals in the higher elevations mostly extending from the 750 foot elevation line to the ridgetop at 1,120 feet. The City of Sausalito is bisected by the U.S. 101 freeway that runs adjacent to the City of Sausalito boundary. The Wolfback Ridge Homeowners development is on the west side of the freeway and is unincorporated. The remainder of zone 1 lies in the Golden Gate National Recreation Area and is structurally protected by contract by our Fire District.

Zone 4 (Tam & Homestead Valley)

Zone 4 (Tam & Homestead Valley) is a rural type of suburb consisting of mostly single family dwellings built in and upon the coastal mountain range. There is a few small portions, about 5%, that resides on the valley floor. It has a very small commercial area on the valley floor in Tamalpais Valley. This zone is split into essentially two parts: Tamalpais Valley and Homestead Valley. The division between the two valleys is the sharp mountain range running from west to east that divides these two communities although the area is still built out with very large single family dwellings and a few schools. The fuels in these areas are mostly Oak woodland, Bay stands in the deep canyons, Eucalyptus stands with heavy downed material, and between most of the home parcels are sporadically planted or volunteer pine trees with thick beds of needle cast some of which is overgrown with black berry patches and annual grasses. On the perimeter of most of zone 4 lays portions of untreated Golden Gate National Recreation Area consisting of coastal chaparrals and numerous stands of Eucalyptus stands that have not been maintained.

Zone 6 (City of Mill Valley)

Zone 6 (City of Mill Valley) represents the original portions of Mill Valley incorporated in 1901. Zone 6 (located at Mill Valley City Hall) is primarily residential with some light commercial located in Downtown Mill Valley. The zone is located at a confluence of canyons and ridges such as Blithedale, Cascade, Warner, and Middle Ridge. Major roads include servicing the area include Miller Ave, E. Blithedale, W. Blithedale, and Summit. Although a large portion of the zone is located in the Wildland Urban Interface, a substantial portion of the Mill Valley flat areas are located in the flood zone at the confluence of many streams and drainage. Residential occupancies are substantially single-family homes, multifamily homes, and a few mixed-use occupancies. The zone includes several restaurants, a pharmacy, Park Elementary School, Old Mill Elementary School, and government facilities. Zone 6 is bordered by unincorporated Mill Valley, City of Larkspur, Marin County Open Space, and Marin Municipal Water District Lands.

Zone 9 (Strawberry, Alto Sutton & Almonte)

Zone 9 (Strawberry) is a residential community consisting of the Strawberry Area, the Alto Bowl and the newer part of the zone that we call the Black Field area. There is a very large commercial area in this zone that also runs parallel to US Highway 101. The commercial area has a variety of businesses such as Safeway Food Store, Porsche of Marin, Chevron and it also is the home of the Golden Gate Baptist Seminary which is 148 acres. This large chunk of land has many residential and commercial buildings on it but are generally separated by large expanses of open grass lands dotted with large Pine trees of which many of them are maintained. The other part of the zone touches the Ring Mountain Open Space area which is predominantly ungrazed grass lands that directly abut the residential area. The homes in this area are mostly Mediterranean style with stucco siding and tile roofs. A large portion of this area is built on the hillsides as well but the streets are much wider and newer.

Residents of Southern Marin are encouraged to participate in Southern Marin Fire District's "Did You Hear It?" (DYHI) campaign. DYHI was developed to tap the abundant information available about the on-going LRAD monthly testing from residents who experience them within Southern Marin Fire District's jurisdiction. By taking advantage of the vast number of Internet users, we can get a more complete description of what people experienced, the effects of the monthly testing, and the extent of missing coverage. And best of all, with your help we can do so almost instantly.

Be a part of our team and share your experience with our NEW "Did you hear it?" form. As a reminder, don't call 911 when you hear the sirens or as a means in providing feedback to the "Did You Hear" campaign. Use 9-1-1 for life-threatening emergencies only. If you hear the siren at any other time, please tune into KQED 88.5 FM, KCBS 740 AM or KGO 810 AM, as well as, local TV stations for further information.

By contributing your experience of the notification system, either immediately afterward, or whenever it is possible for you to do so, you make a contribution to the body of information about each activation of the system. You also ensure that your area has been represented in the evacuation drill and siren testing network. This is a two-way street: not only will you add valuable information on the extent of the system coverage, but in the process we hope you will learn more about how other communities gain a greater understanding of this part of the emergency notification system.

DYHI data are now being used in a number of applications. For example:

Providing sound sculpting data for coverage and future site locations.
Evaluating community understanding of the notification system.
Educating the public of why monthly testing is required in the area.
Comparing the results of sound projection maps with DYHI responses.

How will I now if testing is in my neighborhood?

Emergency testing of the notification system is actively underway on the first Saturday of the month at 12 noon within the City of Mill Valley, Tam Valley, Homestead, Strawberry, Sausalito, Eastwood Park and Homestead Valley.

Long Range Acoustic Device (LRAD) emergency alert systems are unique in that they can project both siren and voice recordings to alert and inform community members during a large-scale disaster.
