We heard from many of you after our last newsletter's subject line regarding the song title "Don't FENCE Me In."  This old favorite was written by Cole Porter and sung by Roy Rogers, Bing Crosby and many others (both in tune and out of tune). This week we'll continue the fencing theme with a focus on installation. We hope you find our newsletter enjoyable and informative and, as always, we appreciate your feedback. 

 

Sand Drift Fencing Installation- Think Zig-Zag!

In designing a sand drift fence consider the following:   

 

1.  A sand drift fence is not a straight line fence; sand drift fencing is most effective in a zig-zag configuration.  Straight line sand drift fence is best used for pedestrian or vehicular control such as wood and wire directing beach goers to access points, keeping folks off dunes that you are trying to rebuild or vegetate, or keeping cars from parking on a beach face.

2.  Most sand drift fence costs are presented in terms of fence lineal feet not beach lineal feet.  Since drift fencing is zig-zag, the number of lineal feet of drift fence will always exceed the number of beach lineal feet.  The angle of the zig-zag will usually not be less than 30 degrees and can reach 45 degrees.  Of course, the steeper the angle of the fence, the more drift fence that will be required and thus the greater the cost.

 

3.  Sand drift fencing works best where there is a wide beach face and a lot of sand that can be wind swept along the beach and caught by the drift fencing where it will be deposited between the zigs and the zags of the fence or behind the fence.  Sand drift fencing installed on beach where the beach face is mostly silts and clays and only a little sand, will result in minimal sand accretion.

 

4.  In the early days of sand drift fencing, cross bracing was used to reinforce the mid panel span.  Cross bracing, while a good idea in terms of fence stability, is not such a good idea in terms of safety, particularly on an actively used beach.  Children (and adults) will stand/sit on the cross braces of the fence, and occasionally the braces will break.  The safety issue is obvious in terms of potential cuts and bruises or falling on to the panel slats which can result in a very nasty injury.  Thus, we recommend rather than cross bracing, using mid span posts as the fence panel reinforcement method.
