How an 1870 decision to build 1,013 acres of park on San Francisco's western sand dunes severed the city's street grid — and how the Outer Richmond (11 evictions, 458 311 calls, $250K permits in the past month) and the Sunset (zero on all three measures) still read as different cities on either side of it.

At the 700 block of 14th Avenue, just north of Golden Gate Park's Panhandle end, an eviction notice was filed July 21. It was one of 11 filed in the Outer Richmond in the last 90 days, according to DataSF, which also logged 458 311 service requests from that neighborhood in the past week. Across the park — on Lincoln Way, where the Sunset district borders the same 1,013 acres to the south — DataSF returned zero eviction notices and zero 311 activity in the same windows.

Three miles of park sit between those two streets, all of it the result of a single 1870 act.

That year, the California legislature authorized San Francisco to issue $225,000 in municipal bonds to develop a public park on the windswept, shifting sand dunes of the Outside Lands, per SF Recreation and Parks Department records. The city's orthogonal street grid, which runs east of Stanyan Street without interruption, was never extended westward through the new park. William Hammond Hall, appointed the park's first engineer in 1871 after winning a competitive topographical survey bid, applied what historian Meldahl, speaking to KQED, called Olmsted's concept of "the genius of place" — the idea, as Meldahl put it, "that you would work with what nature created instead of leveling everything." Hall stabilized the dunes by planting grasses and lupine on their leeward sides first, building topsoil up from the bottoms of natural valleys. Where the grid's implied westward extensions would have run, there were instead winding paths and sheltered hollows.

Hall was pushed out in 1876 when D.C. Sullivan — a former blacksmith and state legislator Hall had fired for contract padding — fabricated allegations against him and led a campaign to halve his salary. The entire Park Commission resigned alongside Hall in protest, according to KQED's account. John McLaren, hired as superintendent in 1890 and serving until 1943, carried the naturalistic vision forward, reportedly planting shrubs around the park's monuments until they disappeared from view.

The park's footprint runs east-west, a continuous three-mile interruption between the Richmond and Sunset districts that each surrounding block has navigated on its own terms ever since.

That asymmetry shows up in the permit record as well. On Fulton Street — running hard along the park's northern edge through the Outer Richmond — two significant alteration permits were filed in late June: permit 202606304213 at 5600 Fulton St ($250,000, filed June 30) and permit 202606294127 at 1608 Fulton St ($197,000, filed June 29). On Lincoln Way, along the southern Sunset edge, the most recent permit on record is a $2,000 alteration at 4201 Lincoln Way (permit 202607074646, issued July 7). The northern edge is the more active one, in the data and on the ground.

The 11 eviction filings in the Outer Richmond over the past 90 days are spread across the neighborhood — the 700 block of 14th Avenue, the 400 block of 43rd Avenue, the 3400 block of Balboa Street. Set against the flat zero on the Sunset side, the difference is at minimum worth noting: the same park, the same age, two different pressure readings depending on which side of the dunes you're standing on.

Walk from Stanyan Street to the ocean and the break in the grid is invisible. Stand at Fulton, look south, and the other side might as well be a separate city.
