Provide a continuous line of defense around the site as far from the building as practical.
Place vehicular access points away from oncoming streets.
Limit the number of vehicular entrances through the secured perimeter line
Use a series of landscape features to create an obstacle course between the building and the perimeter. This approach is most effective if used in areas where there is ample setback.
Design planters for the design-level impact to displace the planter a distance less than the setback.
Use anti-ram barriers along curbs, particularly on sides of the building that have a small setback and in areas where high-velocity impact is possible.
Use operable anti-ram barriers at vehicular access points. Select barriers rated to provide the desired level of protection against the design impact.
