Biofence Specification

I am trying to get to 100% biodegradable, recycled, reusable, recyclable, low impact best management practices.  I have used burlap fabric fence several times, anytime it makes sense, really.  I use it whenever I can leave it in place to degrade, like on habitat or wetland work.  In one of the photos, plastic zip ties are used to attach the fabric to the wooden stakes; this is a mistake and has been changed to staples in the specification.

Biofence Specification

Materials
U. BIOFENCE
A. Biofence shall consist of 7 ounce or heavier uncoated burlap fabric at least 36 inches wide and 100 feet long. Wood stakes dimensions shall be a minimum 1 1/8 x 11/8 inches by 42 inches high.

Construction Requirements
18. Biofence
a. Stakes shall be driven into the ground a minimum of 12 inches and be spaced no more than 6 feet apart.
b. Fence ends shall be joined by wrapping ends together around a post 3 times and driven into the ground.
c. Burlap fabric shall be attached to the post in at least 3 places using staples or other method approved by the Engineer.
d. When used as a barrier fence, fabric shall not be trenched into the ground. When used as a silt fence, a minimum 8 inch flap shall be left at the bottom and held in place with straw wattles staked in as detailed in item 9 above.

Payment
C. Payment for “TESC – Biofence” will be made at the contract unit price per linear foot as stated in the Schedule of Unit Prices and shall be full compensation for furnishing all labor, equipment, materials and tools necessary to complete the installation of the biofence as detailed on the drawings or as directed by the Engineer and specified herein. The unit price shall include all maintenance, the removal of biofence, and restoration of the area at the completion of the work

Horizontal Silt Fence

Walking around South Congress district south of downtown Austin, I discovered a new best management practice-horizontal silt fence. This makes access to the work area so much easier than if vertical silt fence was used. Fortunately no rain in the near future.

Didn’t find much in the way erosion in Austin, but had a great time at Roadhouse Relics visiting with the owner, Todd Sanders.
