clearance shall be provided in all zoning districts so that no fence,
wall, architectural screen, earth mounding or landscaping 30 inches or
higher above the street center line obstructs the vision of a motor
vehicle driver approaching any street, alley, or driveway intersection
At a street intersection, clear vision must be maintained for a minimum
of 25 feet across any lot measured from the corner of the property line
in both directions.
At an intersection with an alley, this clearance must be maintained for 10 feet

in the visual clearance areas of all districts.
A limited number of single-trunk trees having a clear trunk (branching)
height of at least eight feet may be located within sight visibility
areas provided that they are spaced and positioned such that they will
not produce a visibility inhibiting effect when they attain mature size.
