Send me a pointer to the data, assure me they are ODbL-OK and I'll "merge" these into OSM.

Any help maintaining San José’s sprawling, unwieldy city limits would be 
most welcome. A few years ago, I incorporated the Seven Trees 
annexations into San José [1] but didn't go much further to correct the 
crude, outdated data we imported from TIGER.

Thankfully, over the years, Steve has impressed upon me the importance 
of Santa Clara County's Local Agency Formation Commission (LAFCO), which 
serves as the authority on municipal boundaries in the county and 
conveniently releases all its work into the public domain, by virtue of 
being a state agency. The commission's Island Annexation Program page 
[2] links to a memorandum from May 2011 [3] and an atlas from 2015 [4] 
that include detailed maps of the remaining islands.

The county planning department handles GIS for the LAFCO. They have an 
ArcGIS application and layer indicating all the city and town limits in 
the county. [5][6] The planning department is also subject to state 
sunshine laws regarding the public domain.
