Three methods are shown in Fig. 2.50 for designing driveways between the curb
line and sidewalk to provide for turning vehicles. Other designs may be used if they are
approved for use by the local governmental agencies responsible for maintenance of the
project. Additional details are shown in Fig. 2.51 when the tree lawn is less than 6 ft
(1.8 m). Residential drives on curbed streets should use a dropped curb as shown in
section B-B of Fig. 2.50.
