Dimond Canyon
Valley of Sausal Creek in the Oakland Hills.
Hugh Dimond purchased this land in 1867. After making a fortune in the mercantile and liquor trades during the Gold Rush, he retired to the valley in 1877, building a home in what is now lower Dimond Park (this house burned in 1913). He died in 1896. The same year, his son Dennis Dimond moved the adobe bricks from the original Luis Peralta home to the canyon, using them to build a small cottage. The property was sold to the city of Oakland in 1917. For years, the adobe cottage was used as a Boy Scout headquarters.

Dumbarton Bridge
DeLorme Northern California  p.105  D-5. 
The original automobile bridge between Dumbarton Point in Fremont and Ravenswood Point in Menlo Park was opened in January 1927. It was the first vehicle bridge crossing San Francisco Bay (only 1.2 miles over water at this point). It was a low-level bridge with a lift span. In December 1984 it was replaced by a new high-level bridge carrying three lanes of traffic in each direction. The bridge is located within the Don Edwards San Francisco Bay National Wildlife Refuge. A walkway above the toll booths connects the refuge with Coyote Hills Regional Park to the north via hiking trails. There is also a railroad bridge south of the highway bridge, but it went out of use in 1982. There is talk of restoring rail service across the bridge as part of a new commuter rail service.

Dumbarton Point
DeLorme Northern California  p.115  A-5. 
Point in Fremont on the eastern shoreline of southern San Francisco Bay, where the shoreline turns eastward toward Mowry Slough. With Ravenswood Point on the western shoreline, Dumbarton Point forms the narrowest spot in the bay. The first Dumbarton Bridge across the bay here was built in 1927. A Scots investor, J Barr Robertson, obtained ownership of a townsite near Jarvis Landing. He named the point after Dumbarton Point in Scotland (where the River Clyde enters the North Sea), and called the townsite Newark after the castle on Scotland's Dumbarton Point. In 1875 work was begun on a railroad from Dumbarton Point through the townsite, but the project never got past initial grading. The next year the project was bought out (see Newark) and became part of the South Pacific Coast Railroad, a narrow gauge railroad from Dumbarton Point to Santa Cruz (later extended north to Alameda and ferry connections to San Francisco).

Dunsmuir House & Gardens
Alexander Dunsmuir came to the Bay Area in 1878 to oversee the family business here (his father was a wealthy coal baron in British Columbia). He bought a large estate in the East Bay Hills, with rolling hills, farms, and fruit orchards. He built an elegant mansion in 1899 as a wedding gift for his fiancee Josephine, but Alexander died in New York on their honeymoon and Josephine lived alone in the new house until she died in 1901. The estate was purchased in 1906 as a summer home by I W Hellman Jr, a Wells Fargo Bank executive. The Hellmans called it Oakvale Park. The mansion was remodeled and enlarged in 1913. Mr Hellman died in 1920, but Mrs Hellman lived there until the late 1950s. In the early 1960s, Oakland purchased the estate, intending to create a conference center. When these plans did not work out, a nonprofit organization was created to preserve and restore the estate, which was owned by the city and jointly operated by the city and the nonprofit group. In June 1989, the nonprofit Dunsmuir House and Gardens Inc was given full responsibility for operating the 50-acre estate as an educational, historical, cultural, and horticultural resource.

D.U.S.T. Marsh
Marsh in Coyote Hills Regional Park that purifies stormdrain runoff. The acronym stands for Demonstration Urban Stormwater Treatment. The marsh was constructed in the early 1980s by the Association of Bay Area Governments (ABAG) as a model to study the effectiveness of using wetlands to remove pollutants from urban runoff before allowing it to flow into the Bay. Today the marsh is maintained by the Alameda County Flood Control and Water Conservation District, and it remains one of the few examples of successful stormwater treatment projects in the world.
