Turning a slip lane into a plaza

I’m sketching a quick-build plan to convert a 12 m slip lane in downtown Oakland into a pocket plaza with trees and movable seating; for those who’ve done this, how did you handle drainage and loading access without killing the vibe? Any lessons on curb reveal and minimum turning radii that worked on site?

I’ve had luck keeping the existing gutter live by pitching the surface about 1.5% to a single low point and cutting a 300 mm ‘scupper’ through the planter line into the existing inlet, which avoids trench drains and keeps the plaza vibe intact. As a small caveat on loading, I used a 50 mm mountable ‘curb reveal’ with removable bollards at one end and limited hours so it didn’t read like a drive lane. Does your 12 m segment have an inlet on the downhill side, @OP?
