The Calendar Entry That Won't Expire
Eighty volunteers painted the Detroit Steps mural in two-hour shifts last summer. Public Works ran a feature. The neighborhood had its before-and-after. Then the project ended, and Rosaura Valle kept a recurring line on the SNA calendar: maintenance day, last Sundays, 10 a.m. to noon, Detroit and Hearst. Sweep, weed, pick up litter. She lists one still, nine days from now. The mural gave the upper stairway a public identity. Valle's contribution registers in a quieter place — in what happens when leaves collect on 186 concrete steps and someone decides, month after month, that they still warrant sweeping.
The Calendar Entry That Won't Expire
Eighty volunteers painted the Detroit Steps mural in two-hour shifts last summer. Public Works ran a feature. The neighborhood had its before-and-after. Then the project ended, and Rosaura Valle kept a recurring line on the SNA calendar: maintenance day, last Sundays, 10 a.m. to noon, Detroit and Hearst. Sweep, weed, pick up litter. She lists one still, nine days from now. The mural gave the upper stairway a public identity. Valle's contribution registers in a quieter place — in what happens when leaves collect on 186 concrete steps and someone decides, month after month, that they still warrant sweeping.
What It Costs
In 2019, the District 7 Participatory Budgeting process awarded the Detroit Steps Project $25,000 for 186 publicly owned steps. What followed was not a straight line from funding to construction.
Between $5,000 and $6,000 of the project's funds sat with the San Francisco Parks Alliance, the fiscal sponsor that collapsed in June 2025 after misspending millions in restricted community funds. As the Ingleside Light reported that September, phase two was being funded out of pocket. Tad Sky had spent $2,000 on paint and equipment. A mural permit cost $529. The archway's Tier 3 Love Our Neighborhoods encroachment permit would have added $1,076, until Ordinance 075-25 waived the fee that May.
Eighty volunteers painted the steps in two-hour shifts. The permit filings, the lost funds, the out-of-pocket receipts: that was the work around the work.
A Pattern of Entry Points
Every summer, AAUW San Francisco sends fifteen girls to Tech Trek, a week-long residential STEM camp on a college campus. Since 1998, more than 16,000 students have attended statewide. Then the week ends and they scatter.
Valle, who earned a PhD in molecular biology from the Université Denis Diderot-Paris and spent years as a research scientist at NIH and the FDA before moving to Bay Area biotech, saw what was missing. According to her AAUW California bio, she has coordinated SF-TTAG, the branch's Tech Trek Alumnae Group, since 2020. The program she built offers college-readiness workshops, STEM career panels, a monthly newsletter, and a scholarship of up to $16,000 over four years. A one-week camp became a program that lasted through high school and into college.
Her SNA board bio also mentions a STEM leadership program for high school students. She has served as AAUW-SF branch secretary since 2019. And since 2018, she has organized a monthly maintenance day on the Detroit Street steps, last Sundays, 10 a.m. to noon. Three volunteer commitments in three different domains. In each one, Valle took a system that already existed and added a regular, recurring gathering point where someone new could show up.
What Maintenance Makes
The bronze steel fencing along the Detroit Steps has ball finials on the posts, the same color as the fence at the Sunnyside Conservatory. A decorative choice coordinated across two neighborhood landmarks, visible to anyone climbing between Monterey and Joost. Sustained care produces that kind of coherence across public space.
San Francisco Public Works documented the broader transformation in July 2025: tended landscaping, an irrigation system, native plants, benches. On the 115 upper risers, a mural called "Winter Stream," designed by Sunnyside resident artist Tad Sky, depicts a creek winding among stones and wildlife. The stream references Islais Creek, diverted underground in the 1910s, now remembered in paint on the steps above it.
All of this depends on a monthly maintenance day, last Sundays, 10 a.m. to noon. Volunteers sweep, weed, pick up litter. Two hours, no experience required, and a reason to be on the same staircase at the same time.
Sky told the Ingleside Light what comes of that regularity: "When you do something beautiful, not only does it inspire people to do more nice things, but you meet so many neighbors that you probably never would have met before."
