We used 12-inch-diameter socks, five rows thick at the bottom, five rows high, stacked like a pyramid.” Unlike the ancient Egyptians, Farris assembled his pyramid the easy way— building the “blocks” in place. “As big and heavy as these socks would become, it would’ve been too labor intensive to move them in prefilled. So, once we determined the layout for the Channel Soxx, Summit Erosion Control’s crew filled them onsite with a blower truck. This didn’t take long; Summit was fin-ished with the whole project in a day and a half. Once the dam was in place, Summit blew on a compost blanket with native seed in it so we could vegetate the dam and create a natural barrier for the sand that would also filter the large volume of water coming off the cliffs.” Channel Soxx saved time and money as well as stopping the sand. “We don’t have to worry about cleaning these up once they’re in, and compared to tra-ditional sandbagging, these socks are much less labor intensive. Channel Soxx are more affordable. And, in this case, you have the added bonus—the Channel Soxx Summit uses last much longer than sand bags and in place, and the compost is a good growing medium for revegetation.” This was the first time LandGraphics had used Channel Soxx, and the experi-ence convinced Farris that the product could open up new business opportuni-ties for his firm. “For us, what we can do with Channel Soxx creates another service we can offer our clients, to meet a variety of needs. We’ve also worked on construction sites where the land might lie dormant for a couple of years due to the economy. Channel Soxx would be a great fit on many of those projects.” Socks Onsite and Door-to-Door Summit Erosion Control uses Filtrexx products on many construction sites. “A prominent San Diego home-builder has been using Filtrexx products for the past year,” says Craig Kolodge, Ph.D., director of business development for the Poway, CA–based company, which is that area’s Filtrexx certified manufac-turer. “The Filtrexx SiltSoxx are installed both when the subdivision’s roads are in, but houses have not yet been built, and during active construction.” In one such development, approxi-mately 160 acres of open land were graded, with roads and pads in place. “This is an extremely environmentally sensitive area, with streams and very mobile silty soil. The area had to be sta-Unlike the ancient Egyptians, Farris assembled his pyramid the easy way—building the blocks in place. bilized; any runoff could threaten the quality of the receiving waters nearby. The developer invested a lot of money to meet California’s permit regulations; the company wanted BMPs with good research behind their performance, and they wanted something that would last. Compost addresses NDPES [National Pollutant Discharge Elimination System] Phase II requirements, fil-tering sediment-laden water through compost and maintaining quality of receiving bodies of water. The client standardized on Filtrexx compost socks for sediment control and as a slope in-terruption device.” Filtrexx launched a new nation-al pallet program in 2011. “Compost socks can be manufactured two ways,” Kolodge explains. “They can be made onsite, filled in place with a blower truck. A filled 8-inch-diameter sock weighs approximately 13 pounds per linear foot; because it’s heavy, it stays in place and doesn’t require trenching. Sometimes, though, palletized socks are more portable, and allow the end-user to move socks where they need them, as well as stockpile extra if needed. When we couldn’t get a blower truck to their site, we’d palletize compost socks at our production yard in Chula Vista.
