grade and any increase in grade.
c. Driveway Side Slopes. The side slopes of driveways shall be topsoiled, seeded, fertilized and mulched or otherwise stabilized to prevent
erosion. If banks exceed a two to one slope, and the slope face is not stable rock, retaining walls shall be constructed in a manner approved
