New Map: The Creek that Ran Through Sunnyside

By Amy O’Hair
[Revised with additional information December 2023.]

Here is a new map for understanding the historical path that Sunnyside’s tributary of Islais Creek once took through the neighborhood, a composite using color Sanborn maps and historical survey information from the Library of Congress, SF Dept of Public Works, and DavidRumsey.org. Additional information for areas not covered by Sanborn from Joel Pomerantz’s Seep City project for mapping our city’s old waterways.

A culvert was installed from one side of Monterey to the other at about Edna Street in the 1910s. Part of the creek was contained in a box drain in the 100 block of Flood Ave (north side) about the same time. Other manipulations took place, until the City diverted the water that would have fed it into the sewer system, during the 1920s.


My thanks to Kathleen Laderman for finding the rich vein of early detailed survey information in the historical Dept of Public Works Field Notes section of the SFDPW website, giving a priceless glimpse into the lay of the land when Islais still ran through our district.

Sunnyside’s Missing Mini-Park

By Amy O’Hair

If not for the hapless mistakes made by the Sunnyside Land Company in 1891, our district would have no parks at all. An ill-advised street layout meant that some lots were too steep and rocky to build on, leaving them vacant for decades. This resulted in enough conjoined lots that the City, two generations later, could buy up and create the Sunnyside Playground and Dorothy Erskine Park.

Planned streets that were in fact too steep to be built have also been transformed into open space, as in the Detroit Steps Project, the Melrose Detroit Botanical Garden. A portion of unbuilt Edna Street was incorporated into the Playground as well.

Additionally, by laying out streets without regard to slopes, the City had to later buy up several residential lots in Sunnyside, in order to lay the sewer pipes—which must of course go where gravity dictates. This happenstance has given Sunnyside several small open spaces for public enjoyment, such as the Joost-Baden Mini-Park and the steps behind the Sunnyside Conservatory.

Yet still today there remains a City-owned piece of land—500 square feet in size—that is undeveloped as a public open space. It is fenced off and inaccessible. One half is used as a private side yard by an adjacent homeowner. The other half is currently leased to Friends of the Urban Forest, but that organization has never used it. These non-public uses of public land represent a loss to the community, and it is time the situation was rectified.

First, a short history of Sunnyside’s land and its parks. Continue reading “Sunnyside’s Missing Mini-Park”

Built on Beer: The Streets of Sunnyside and San Francisco Brewery Profits

Investment money that funded the Sunnyside Land Company in 1890 was largely sourced from the hefty profits of some of San Francisco’s biggest late nineteenth-century breweries: Philadelphia Brewery, Albany Brewery, and United States Brewery—all overseen by the Brewer’s Protective Association. Men who were heirs to these fortunes, or wrapped up in the racket of propping up prices and selling off franchises to foreign capitalists, were among the most prominent initial investors in the Sunnyside project.

Behrend Joost, President of Sunnyside Land Company, was a notorious and irascible teetotaler[1], but he had no problem accepting beer-drenched money from his investors, who altogether put in one million dollars to fund the property speculation project. In return, many got their names or the places in Germany they came from on the newly laid-out streets.

Five of the original Sunnyside streets—Mangels Avenue, Spreckels Avenue, Wieland Avenue, Baden Street, and Hamburg Street—I trace directly to these men.

In addition, Edna Street is likely to have been named for the beloved daughter of one of these brewery men. Continue reading “Built on Beer: The Streets of Sunnyside and San Francisco Brewery Profits”

One block in Sunnyside: 50 years ago and today

Fresh from the new collection of building photographs that were recently transferred from the San Francisco Office of the Assessor-Recorder to the History Center–here is one residential block in Sunnyside. More about the collection here.

On a bright overcast day in 1968 or 1969*, an unnamed photographer from the Assessor’s office appears to have shot every house on the 600 block of Mangels Avenue, leaving an unusually complete record of houses there at that time. Continue reading “One block in Sunnyside: 50 years ago and today”

Families on the edge of the forest: Mangels Avenue in the 1910s and 1920s

At the edge of Sutro’s forest of eucalyptus trees, in the northwest corner of Sunnyside, the 600 block of Mangels Avenue was home to several families who enjoyed a truly rural existence in the early years. Recently some photos were graciously loaned to me to scan, so there is some visual record of life there. The photos are from the personal archive of resident Geoff Follin, sent to him in 1987 by a man who grew up on the block during these years—Lawrence Behler (1908-1999).[1] Behler included a brief letter of explanation.

High on a hillside, the Sunnyside sign

Recently a marvelous panorama taken about 1912 came my way. Sparsely populated Sunnyside can be seen in the distance. The image also revealed a remarkable feature from the neighborhood’s past—a giant hillside sign in the style of the one in Hollywood, which was also placed as a real estate advertisement in its day. However, Sunnyside’s sign preceded the more famous one by at least ten years—though of course unlike the one in Hollywood, Sunnyside’s did not last.

Disappeared Streets of Sunnyside

From Sunnyside Homestead map, 1891.

We have lost a few bits of the original streets. The blocks laid out by the surveyor in 1891 were perfectly rectangular and the streets die-straight. All the better to milk maximum profits from the sale of lots–no extra wedge-shaped bits, or wasteful little parks to clutter up the profit landscape. But reality meant changes had to be made in that rigid map in the course of building out the neighborhood in the twentieth century.
