The outlet of Coyote Creek, which drains Tam Valley into upper Richardson's Bay.

Richardson Bay is a shallow, ecologically rich arm of San Francisco Bay managed under a Joint Powers Agency of four Northern California cities[1], after the Richardson Bay Sanctuary was purchased in the early 1960s by the Audubon Society. The bay was named for William A. Richardson, early 19th century sea captain and builder in San Francisco. Richardson Bay is considered one of the most pristine estuaries on the Pacific Coast in spite of its urbanized periphery, since it supports extensive eelgrass areas and sizable undisturbed intertidal habitats. It is a feeding and resting area for a panoply of estuarine and pelagic birds, while its associated marshes and littoral zones support a variety of animal and plant life. Richardson Bay has been designated as an Important Bird Area {or IBA), based upon its large number of annual bird visitors and residents, its sightings of California clapper rail and its strategic location in the flyway. The bay's waters are subject to a "no discharge" rule to protect the elaborate and fragile ecosystems present, including a complex fishery, diverse mollusk populations and even marine mammals such as the harbor seal. Due to its lack of depth and tricky channel structure, Richardson Bay is limited in boating uses to kayaking and small sailing craft. There are extensive hiking and bicycling paths at the bay perimeter, especially in the shore areas of Mill Valley and the town of Tiburon[2].

History of the name designation

On August 22, 1822, an English whaler, the Orion, put into Yerba Buena Cove in San Francisco for supplies; the captain was William Anthony Richardson, described as tall, fair haired, blue-eyed and young, was sighted by Maria Antonia, daughter of the Commandante of the Presidio of San Francisco, Ignacio Martinez. No doubt Martinez, for whom the town of Martinez is named, was influenced by Maria to invite the Captain to reside with their family. Maria soon married the captain, after he joined the Catholic Church being baptized "Don Antonio Richardson." This wedding, held at Mission Dolores on May 12, 1826 was the first great Spanish-Anglo Saxon wedding in North America[3]. 1822 (MDCCCXXII) was a common year starting on Tuesday (see link for calendar) of the Gregorian calendar (or a common year starting on Thursday of the 12-day-slower Julian calendar). ...

Richardson taught carpentry, boat building and navigation at Mission Dolores, served as Captain of the Port of San Francisco, and built the first significant residence in San Francisco, although it was meant to be a trading post. He had charge of several schooners belonging to the Mission Dolores and Mission Santa Clara. Richardson received an 19,500 acre Mexican land grant in 1838, Rancho Sausalito, which is all of the land north of the Golden Gate extending from bay to ocean and ranging north to Mount Tamalpais The grant contained all the land southeast of Mount Tamalpais, and included Redwood Canyon and the lands now within Muir Woods National Monument.

Geology

Richardson Bay is developed on surficial sediments of clays, silts and minor sands and gravels deposited in a primarily marine and estuarine environment during periods of previous high stands of water relative to the present shoreline. The bay muds are widespread in San Francisco Bay and, at Richardson Bay, are approximately 80 to 95 feet deep[4]. The Bay Muds are of Holocene Age (less than 10,000 years of age). They overlie firm alluvial soils which contain two sand layers at 92 and 110 feet, respectively . This section, in turn, overlies shale of the Franciscan Complex, a heterogeneous mixture of sedimentary, igneous and metamorphic rock gathered together in the course of the tectonic evolution of the region from the Late Jurassic to the Middle Miocene. These assemblages of Franciscan rocks are referred to as tectonostratigraphic terrains and two of them, the Central Belt and the Coastal Belt, are in fault contact near Richardson Bay.

Fishery characteristics of Richardson Bay include a Pacific herring fishery and oyster beds. the herring fishing fleet serving all of San Francisco Bay is based in Richardson Bay at the Sausalito harbor. This herring fishing is overseen by the California Department of Fish and Game; the herring population is in a downward trend, although not currently from excessive fishing pressure with the net techniques in use, but rather from ocean environmental factors. Herring spend most of their lives in the open ocean and come to Richardson bay and other estuaries for winter spawning in the shallow protected waters. In Richardson Bay their eggs attach to assorted surfaces such as eelgrass, piers or rip rap. After the eggs hatch, the herring larvae consume plankton; before hatching the eggs are subject to predation by gulls at low tide and sturgeon and other assorted estuarine fauna at higher tides. Binomial name Clupea pallasii Valenciennes, 1847 The Pacific herring, Clupea pallasii, is a species of the herring family associated with the Pacific Ocean environment of North America and northeast Asia. ...

Binomial name Myliobatis californica (Gill, 1865)[1] The bat ray (Myliobatis californica) is a euryhaline eagle ray found in muddy or sandy sloughs, estuaries and bays, kelp beds and rocky-bottomed shoreline in the eastern Pacific Ocean, between the Oregon coast and the Gulf of California. ...

There is also an extensive pickleweed habitat at the western end of the bay, where many acres of mudflat areas are exposed to shorebirds at low tide at the efflux of Pickleweed Creek.

Sequence of modern events

After the death of William Richardson, who never really gained legal control of the land grant, the entirety of the Rancho Corte Madera del Presidio was owned by John Thomas Reed. Through the latter 19th century and early 20th century the land was extensively subdivided into public and private ownership encompassing hundreds of parcels fronting on Richardson Bay. the cities of Tiburon, Mill Valley, Belvedere and Sausalito have enacted strong shoreline development policies to protect the perimeter of Richardson Bay, even though considerable development has occurred. One parcel deeded from Reed to Rosie Verall, who worked for the Reed family is now the core of the Audubon Richardson Bay Sanctuary. Verall donated this land of approximately 13 acres to be held in permanent trust as a wildlife sanctuary. The Audubon Society purchased this upland parcel along with the entirety of the subtidal and intertidal lands of Richardson Bay in 1960. the Audubon Society manages the whole Richardson Bay Sanctuary subject to governance by the Joint Powers Agency of the four peripheral cities. The Lyford House built in 1876 occupies the Verall parcel, even though the house was originally built at a different location in the vicinity known as Strawberry Point.
