Here's a quick rundown of the way I got the "Streets" delay after some research. Try them in your unit and see what you think, and by all means play with the settings to see if you can make them better.
Effect: DigitalDelay
Tap Tempo: 129bpm
Mix: 39
Dly Mix: A5+B10
Dly Time A: 1/32
Dly Time B: 1/8•
Fdbk A: 30

(You might try adding some modulation to the echos for a little lushness)
