TECHTALK
by Dr. Jim Spotts
TechTalk is a forum for resolving erosion and sediment control and/or construction related problems from a technical perspective. Technical questions are submitted by the reader; suggestions may be from Southeast Environmental Consultants, LLC, (SEC) or other sources. The reader is solely responsible for the results, if the suggestion is implemented.
Question: I see a film of fine sediment coating my sediment barriers (silt fences). How can I get it off? I don't want to replace this BMP each time it rains. Response: Let the "skin" dry out. Then either beat the backside of the fabric with a stick or try blowing it off, again from the back side, with a leafblower. |
What is Soft Armoring, and can it prevent my slope from eroding?
Soft Armoring is the process by which soft, pliable open-weave matting (i.e. jute, coir, coconut, hemp, burlap, etc.) is placed onto the soil surface. The soil-specific polymer is then applied, and reacts with the metals and clays within the soil to bind it together. This complex attaches to the matting, creating a highly erosive resistant surface that will support vegetation along with aiding in attachment of fine particulate to the matting surface.

Construction Company Ordered to Restore Damaged Wetland and Stream
Michael Rodriguez and his company, Christian Brothers Construction, have been ordered by the U.S. Environmental Protection Agency (EPA) to restore the wetland and stream that his company illegally filled and channelized without a Clean Water Act permit. According to EPA, in October 2008, Mr. Rodriguez illegally filled 1.7 acres of wetlands and filled and channelized 1,680 feet of Tenmile Creek. Mr. Rodriguez failed to obtain the required Clean Water Act Section 404 permit from the U.S. Army Corps of Engineers (Corps). Before this violation, Mr. Rodriguez was told by the Corps that a permit was required for his proposed work, but he failed to apply for one. MORE |
