Denver Dirt Pile

Just a nice dirt pile in Denver. Walking around between presentations at the International Erosion Control Conference in February 2019 and saw this. A little utility work in the street, going to reuse the excavated dirt, placed it on plastic, put some berms around base, no rain in the forecast and the dire goes back in the hole later in the day so no need for cover.

Truck Being Loaded on Asphalt Keeps Tires Clean

If I’ve said it once, I must have said it 3 or 4 times: “Keep your tires clean!”. Who wants to use a tire wash and have to get rid of a whole lot of dirty water (process water) that can’t go down the storm drain? Save yourself some hassle and money. Give your employees a raise with the money you save.

The Soaker Tire wash

These are great as long as the tires are not too muddy, the mud is not too sticky and the vehicle load is not too high. Most of the water is directed to the sidewalls and misses much of the mud hiding in the treads. These work great as the final , clean rinse cycle in conjunction with a tire bath best management practice. Chemical flocculants can be added to the water to remove much of the sediment load.

Description from the website: http://www.thesoaker.com/

“The Soaker” is a portable, self-contained and environmentally friendly wheel washing system. The system does not require city power or water connected to it which makes it highly portable.

“The Soaker” can be installed on job sites, dump sites and material pits to help keep the surrounding streets free of mud and dirt.

Its aluminum and stainless steel construction makes “The Soaker” environmentally friendly.

It features a high capacity main tank of 4000 gallons and a reserve tank of 2000 gallons. Its adjustable spray heads provide a low pressure/high volume water stream of up to 1000gpm. Motion sensors detect the vehicles on approach and turn on the pumps so the water spray is at full power by the time the vehicles go through the wheel wash.

“The Soaker” is manufactured to provide solutions to problems such as portability, road pollution, costly cleaning processes, fines and violations for depositing debris onto public highways, etc…

“The Soaker” can be rented on a monthly basis or purchased. A lease purchase option is also available. For more information about “The Soaker” wheel washing system, please call us at: (818) 952-6752 or email at: soakerinfo@thesoaker.com

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.
