I georeferenced a map, from the #Peralta Family Manuscripts held the #Oakland History Center. It's here in 300dpi, zoom-able. (46MB) If you want the qgz and related files for QGIS, I'm happy to share them.

This is the 1859 Plat of the Northern Part of the Rancho San Antonio, AKA one of the first maps of what's now #Emeryville, #Berkeley and Oakland. There is not much detail within its boundaries, but the homes of Victor Castro and Domingo and Vicente Peralta are where we'd expect. (Note, Vicente's home was near modern Vicente Way.) The road crossings at the border, and across #LakeMerritt all match modern roads. I was able to find enough common points on our modern city/county border to #georeference it; most hadn't changed.

If "Spread Love - It's the Brooklyn way," was a mayoral candidate - take it from this Haitian Bay Area elected from #Brooklyn -#ZohranMamdani is the future. #Emeryville

No no no no no no no! INNA Jam in #Emeryville is closing!

I've recently cut down the amount of alcohol I regularly drink by about 95% because I started ordering their shrub and having it shipped up from the #BayArea.

For over 15 years, Mr Donahue has reported on #Emeryville politics...from toxic waste sites to addressing the genocide in Gaza, his annoying tenacity has rattled some powerful cages, and now those forces are striking back.
