It turns out that the land is owned by the city, and the property is APN 7536-018. While it doesn’t have an official name, you can just think of it as the 29th and Diamond Open Space.
The lot is fairly large, and is also fairly steep… from looking at city records, it appears the grade on the site exceeds 20%, which probably explains why the city still owns this land in Noe Valley and it hasn’t been snapped up by a developer.
What are your thoughts about this patch of green at 29th and Diamond? Should the city keep it as is, consider selling it, or otherwise improve the property to be of more benefit to the neighborhood?
We’d love to hear your thoughts in the comments below.
