A
pair of odd, towering twin columns in Mill Valley, CA (Marin County)
are what met Prowell's site visit. A generally wooded, isolated homestead
required an open design. This photo was taken two years after installation.
A steep uphill drive, requiring out-swinging
Driveway Gates, with embedded steel frames. For out-swing gates,
there is the option to mount the motors on the street side, as seen
below, If the motors are mounted on the inside, the motor arm
has an added elbow, essentially pushing the gate open, with a loss
of approximately 13" of clearance.
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.
--A third option is the "in-ground" operator, such as the Viking
or SEA, which rests beneath the gate with a pin hinge system. A
popular system with a low visual profile that is explained to some degree
on the Specifications page. |
