About Mill Valley

Mill Valley is a city in Marin County, California, United States located about 14 miles (23 km) north of San Francisco via the Golden Gate Bridge. The population was 13,903 at the 2010 census.

Mill Valley is located on the western and northern shores of Richardson Bay. Beyond the flat coastal area and marshlands, it occupies narrow wooded canyons, mostly of second-growth redwoods, on the southern slopes of Mount Tamalpais. The Mill Valley 94941 ZIP code also includes the following adjacent unincorporated communities: Almonte, Alto, Homestead Valley, Strawberry and Tamalpais Valley. The Muir Woods National Monument is also located just outside the city limits.

The Mill Valley 94941 area lies between Mt. Tamalpais on the west, the city of Tiburon on the east,the City of Corte Madera on the north, and the Golden Gate National Recreational Area (GGNRA) on the south. Two streams flow from the slopes of Mt. Tamalpais through Mill Valley to the bay: the Arroyo Corte Madera del Presidio; and Cascade Creek. Mill Valley is surrounded by hundreds of acres (hectares) of state, federal, and county park lands. In addition, there are many municipally maintained open-space reserves, parks, and coastal habitats which, when taken together, ensconce Mill Valley in a natural wilderness. This close and constant proximity to nature has left generations of Mill Valley residents with a strong sense of conservancy toward much of this natural environment. This unique cultural attitude, along with the many natural public spaces preserved within and around its borders, combine to form one of the main cultural cornerstones that has always defined Mill Valley.

Mill Valley has a mild Mediterranean climate which results in relatively wet winters and very dry summers. Winter lows rarely drop below freezing and summer highs rarely peak 90 °F (32 °C) with 90% of the annual rain falling in November through March. Wind speeds average lower than national averages in winter months and higher in summer, and often become quite gusty in the canyon regions of town. California coastal fog often affects Mill Valley, making relative humidity highly variable. The wetter winter months tend to make for a more consistent daily relative humidity around 70-90% (slightly higher than US averages). During the summer months, however, while the morning fog often keeps morning humidity normal, in a typical 70-80% range, by afternoon after the fog burns off, the humidity regularly plummets to around 30% as one would expect in this dry seasonal climate. Sunlight, as with many northwest coastal cities is low, with usually around 130 clear days a year. Marin county is the 4th least sunny place in the United States, after Cleveland, Seattle and Unalaska, Alaska.

The combination of Mill Valley's idyllic location nestled beneath Mount Tamalpais coupled with its ease of access to nearby San Francisco has made it a popular home for many high-income commuters. Over the last 20 years, following a trend that is endemic throughout the Bay Area, home prices have climbed in Mill Valley (the median price for a single-family home is in excess of $1.5 million as of 2005), which has had the effect of pushing out some earlier residents who can no longer afford to live in the area. This trend has also transformed Mill Valley's commercial activity, with nationally recognized music store Village Music having closed, then replaced in 2008 by more commercial establishments.

Mill Valley maintains many recreational parks which often contain playgrounds and other designated areas specifically designed for playing various sports. Dogs are required to be on leashes in all but one of these parks, which is specifically designated a dog park to allow the option of off-leash exercise.
