The original Driveway Gate #16 in Mill Valley, California., Showing a pair of odd, towering twin columns. A generally
wooded, isolated homestead required an open design. This photo was
taken several years after an installation date of 1996.
A steep, almost unnavigable uphill drive,
requiring out-swinging Driveway Gates and motor arms mounted to the street side, pulling the single-span gate open toward the street. (Single span swings require an exposed steel frame to which a pair of gates mount onto, with the steel frame visible on the property side only.)
Most local codes require
Driveway Gates, whether in-swings or out-swings, to be set at least
12' back from the sidewalk or street. The reasoning is to prevent the
homeowner from stopping traffic while waiting for their automated Gates
to open, but also, with out-swings, to prevent them from opening onto
the sidewalk or street. It also allows fire trucks the ability to pull into the drive. Many local codes with homes on trafficked streets require the gates be within 150 feet of the residence, or basically a distance that allows the fire hose to reach a burning house from a closed gate in the event no one is home and the firemen are unable to open the gate.
