• Before construction begins, obtain the rights-of-way from landowners, and
other permits or approvals from public authorities. Place cabinets in
servitudes, on dedicated (recorded) easements, or on property owned by the
company. Avoid any unrecorded easements. Use public safety road and street
rights-of-way only when there is enough space to place the closure and provide
safe working conditions.
• The cabinet should be easily accessible with adequate parking to ensure safety
for people and vehicles. Place the cabinet where it will not create a visual or
physical obstruction to either vehicles or pedestrians.
• Select locations that will minimize accidental or intentional vandalism.
Consider the use of protective posts when the cabinet is located near parking
areas where vehicles could back into the cabinet. Do not place the cabinet in
ditches or areas subject to flooding.
• Place the cabinet at least 42 inches (106.68 cm) away from any obstruction,
fence, hedge, etc.
• If an area is subject to frost, choose a site free of heaving.
• Always locate the cabinet on a site above the 100-year flood plain, and which
is not subject to water runoff or flash flooding during heavy rains.
4.2 Unpacking the Cabinet
4.2.1 MESA®SOLE cabinet is shipped on wooden pallets with plastic covering to protect
the cabinet during shipment.
