Four sites in Sunnyside share a pattern: each is officially designated public space, but what makes any of them feel public to a person standing there is the visible evidence of care.
Sunnyside Conservatory earned Landmark No. 78 in 1975; three years later, a mistakenly issued demolition permit took down a third of the building. What reads as public at 236 Monterey today — the ferns, the bronze fence, the garden passage to Joost — is volunteer work made visible. At the Detroit Steps, a blighted right-of-way became a destination only after signage, native plantings, and a stairway mural gave it a face. Dorothy Erskine Park, dedicated 1979, is still becoming legible, its native grassland half-obscured by invasive grasses the Friends group works to clear. At the Joost and Baden Mini Park, the official city sign competes with a neighbor's stone dachshund for the job of marking the entrance.
As the Sunnyside History Project has documented, all four trace to the Sunnyside Land Company's 1891 failure to read the topography. Streets too steep became stairs; lots too rocky became parks; sewer easements became gardens. The designations came later. What a walker sees at each site is the accumulated evidence of volunteer care.
Sunnyside Conservatory, 236 Monterey Blvd Landmark No. 78, designated 1975. Construction date varies by source: SF Rec and Park says 1898; SF Public Works says 1891; Western Neighborhoods Project says early 1900s. The 1891 date almost certainly refers to the land purchase, not the building.
Detroit Steps, Hearst to Joost 186 steps in two sections. Stairway mural completed Oct. 2025; bronze fence matches the Conservatory's. Next maintenance day: July 26, 2026.
Dorothy Erskine Park, Martha Ave to Baden St Acquired 1977; dedicated 1979 with Dorothy Erskine present. Steep, unmanicured, no restrooms. Native buckwheat, sticky monkey flower, anise swallowtail butterflies when the grasses are cleared.
Joost and Baden Mini Park, Joost to Mangels Built on a sewer easement, open since 1974. Forty feet of elevation gain. Mosaic tile wall, drought-tolerant plantings. Sometimes called "the Butterfly Garden."
