Grading a City Street
This section reviews how to cut sidewalk, curb, and street grade, as
well as cutting a crowned street from existing curb. Street design
varies greatly, so use this as an example and make adjustments for
your job.
Figure 5-45.
For best results, set Sonic Stringline to use as a reference for the
sidewalk grade. Using Sonic Tracker and Slope Control, dial in the
desired grade and slope. Be sure the grade checker verifies the grade
