Hi, can you link to the county assessor map you're using to justify this change? I previously removed the directional prefix from the roads you changed here west of Sawtelle (in this changeset: https://www.openstreetmap.org/changeset/128061187). My reasoning was that the "West" prefix isn't on the street signs in Culver City or Venice/Marina del Rey. In fact, these areas don't appear to use any directional prefixes at all in their addresses/street names as far as I can tell. So I think just "Washington Boulevard" is the more correct name in these areas. I think adding the prefix east of La Cienega is a good change though.

Thanks!
Will
