[Geocoding] Issue with nominatim in Alameda County California (Berkeley/Oakland)

[David Chiles]

Hi

I was using the reverse geocoding api to lookup city and streets. It seems
no matter where in Alameda County I query it returns Alameda as both the
county and city.

For example in Downtown Berkeley:
http://nominatim.openstreetmap.org/reverse?format=json&lat=37.87173&lon=-122.26842&zoom=18&addressdetails=1

In Downtwon Oakland:
http://nominatim.openstreetmap.org/reverse?format=json&lat=37.80408&lon=-122.27028&zoom=18&addressdetails=1

And it seems to work fine in a county and town just to the east:
http://nominatim.openstreetmap.org/reverse?format=json&lat=37.87674&lon=-122.17861&zoom=18&addressdetails=1

I don't know where the problem lies. I couldn't find a problem with the OSM
relations

Alameda (County): http://www.openstreetmap.org/browse/relation/396499
Berkeley: http://www.openstreetmap.org/browse/relation/2833528
Oakland: http://www.openstreetmap.org/browse/relation/2833530
Alameda (City): http://www.openstreetmap.org/browse/way/33083805

Any help on where to look next or what I might be doing wrong
