![]() Also, Salix has been designing and building similar “crossings” for CA State Parks, Off Highway Vehicle Division to use in the SVRAs (State Vehicle Recreation Areas).Īrticulated Concrete Blocks and Low Water Crossings are covered in much greater detail in our ‘ACB Episode’ – available at the WatchYourDirtStore (For more on this install, check out this previous WatchYourDirt Post. ![]() The pictures below show Low Water Crossings built in our local watershed, as part of a 12-year, $1.2 million, grant-funded Sulphur Creek Restoration Projects. Octo Submar Pipeline erosion control, Submar When working with Submar, you will hear the company use several terms relevant to the pipeline erosion control industry. These transition systems not only reduce erosion but they are often aesthetically pleasing and can be designed to increase infiltration. Posts tagged articulated concrete mat () Submar Lexicon: Riprap. These transitions systems include a couple of new products, Scour Stop and Green Armor System. We have also been incorporating a Energy Transition System into our Low Water Crossing designs. We have built them using both Submar ACBs and ArmorLok ACBs (Contech). ![]() As an article from The Courier, dated September 25, 2003, and titled, Matting Services Common Locally, Help Protect Wetlands, indicates, Submar mats were laid along the. A perfect example of this is seen on the Gulf Intracoastal Waterway. SWAG (Sacramento Watersheds Action Group), our non-profit, public benefit watershed restoration group, and Salix Applied Earthcare has designed and built several of the over the last few years. When it comes to erosion control, articulated concrete revetment mats can reduce the risk of runoff. One of the techniques we have been using lately is building low water crossings from Articulated Concrete Blocks (ACBs). Concrete fords have been used for some time but they are difficult to build, forming and pouring concrete in a channel! Building “hardened crossings” out of rock, that can withstand periodic flooding and high flows, can also be difficult. Well, an alternative to culvert crossings are low water crossings. The answer is in understanding that culverts concentrate water, therefore at the outlets there is often a hydraulic jumb ergo EROSION. How can reducing culverts lead to water quality? you ask. Gravel roads, secondary roads, access roads may be best designed without culverts – which greatly reduces cost, maintenance, and water quality problems. So, sometimes, in certain environments, it it best to reduce the reliance on culverts. The “Urban interfaces” in the West are often prone to fire and wildfires can also play havoc with culvert crossings. Culverts sometimes get plugged especially if there is not maintenance.
