Oh wow. That sucks at every level. Glad you are healing up well, and that is the most important part.
As for your crash, it sounds like that loose asphalt and/or the eucalyptus debris was a factor, you may have lost traction in the debris and/or hit the loose asphalt and lost control. I hate to say it too, as others have, but maybe a lawyer? The city is responsible for the bike lane as it is for the street (unless you were on private property). I hate to sound like 'Oh joy, time for a slip and fall lawyer' but there may be something here other than you just la-la'd out and fell over.
Tzvia- rollin' slow...
