Black Point-Green Point is a census-designated place (CDP) in Marin County, California, United States. It is unincorporated, sitting between the city of Novato to the southwest and the Petaluma River and San Pablo Bay to the northeast. The population was 1,431 at the 2020 census.[3]
Black Point was part of the Rancho de Novato land grant. The 1880 History of Marin County by Alley, Bowen and Co. mentions "a man by name of Day" who "settled on an island in Novato township which has since borne his name" in 1851. This island is still known as Day Island. According to the book, several more settlers moved into the area in 1853. Some of them owned land there, while others were squatters, a problem common across the county. Lumber that came from Black Point was used to build part of the USS Saginaw, a steamer built at the Mare Island Naval Shipyard. It served in the navy until 1870, when it ran aground on a reef not far from Ocean island. Deer Island, a former island east of Olive Avenue, actually was an island in the early 1900s. The house on the island, owned by Antonio DeBorba, whose shop on Grant Avenue is still intact, was completely encompassed by water, and his house was only accessible by boat. When both the county and the state refused to build a levee, he spent a small fortune deepening the creek and taking water out of the marsh. Once that was done, he donated the land that is now Highway 37.[4]
The first Black Point post office operated from 1865 to 1891.[5] The Grandview post office opened in 1905, changed its name to Black Point in 1944, and closed in 1952.[5] Black Point-Green Point is located along the Brazos Railroad Subdivision, with Northwestern Pacific running trains through twice a week. Trains passing through Black Point-Green Point cross the Black Point Railroad Bridge, built in 1911.[6] The fields to the south of Black Point were used for the location of the Black Point Communications Annex, an antenna array that was used to communicate with the Hamilton Air Force Base.
Black Point-Green Point is 4 miles (6 km) east of the center of Novato and 11 miles (18 km) north of San Rafael, the Marin county seat. The Petaluma River, which forms the northeast edge of the community, is the Sonoma County line.
According to the United States Census Bureau, the CDP has a total area of 2.9 square miles (7.5 km2), of which 0.07 square miles (0.18 km2), or 2.42%, are water.[2] Black Point-Green Point is also located near various public lands, such as the Rush Creek Open Space Preserve and the Vince Mulroy Wildlife Prerserve.
There are several businesses in Black Point-Green Point, such as Rossi's Deli (an old gas station built in the 1930s), Penske Truck Rental, Kelleher Lumber, and two self-storages. There used to be an inn built during the 1890s, but it burned down in the spring of 1976.[4] Black Point also used to have a train station and a freight depot near the lumberyard.[7] Both the Northwestern Pacific Railroad and the Black Point Aggregates company used to operate a quarry in Black Point to produce ballast and fills for the railroad, as well as shipment abroad.[8][9] The steep scars are still visible, although the flattened area is now part of the StoneTree Golf Course.[10] Black Point was the location of the annual Northern California Renaissance Faire from 1971 to 1998, after which the site was developed into the StoneTree Golf Course.[11]
