F Demo (1 day - 1 month) F Pilot (1 month -1 year) Interim (1 - 5 years) Recommended Applications and Installation ɖBikeways: ɖ Place in continuous line along edge of lane to create barrier. ɖPlazas: ɖ May be combined with planters and other barrier elements to define the edge of a plaza. Place barriers end to end along edge of plaza area, in strategic locations as needed. Not recommended as sole/primary barrier element, due to lack of visual permeability, and aesthetic concerns. Tips and Considerations »» Large item that requires a truck or other large vehicle to transport. »» Hollow design makes loading/unloading easier, when compared to concrete jersey barriers. »» Water needs may make these barriers inappropriate for drought climates or short-term demonstrations. »» May need to space barriers intermittenly to allow curbside access for emergency vehicles curbside access Potential Sources »» Borrow from city public works or parks department »» Buy or rent from traffic control equipment suppliers

Plastic barriers are relatively lightweight / movable but once filled with water onsite create a heavy and durable wall of physical separation. Aesthetics are often a challenge with water barriers, however the above images from Auckland’s Wynyard Quarter illustrate creative adaptations of these barriers, allowing them to act not just as barriers, but also as public art and multi-purpose street furniture.
