While I don't know quite who to call, exactly, if somebody wants to "release to me" ODbL-compatible data which need to be harmonized with what are now in OSM, I'll volunteer to be the "nexus of citizen entry" to assure they find their way into our wonderful map. 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ago, I incorporated the Seven Trees annexations into San José [1] but didn't go much further to correct the crude, outdated data we imported from TIGER.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.
