Erosion Control & Site Management Applications

Applications for Erosion Control & Site Management

• Construction: Construction sites and roadway projects require erosion control measures to keep disturbed soil from leaving the site, stay in compliance with the SWPPP, and avoid enforcement under the NPDES Construction General Permit (CGP) and 40 CFR 122.34 for regulated MS4s. Common problems on active sites include sediment runoff, soil washout, and runoff on slopes. Contractors, site superintendents, and municipal crews rely on Clarion Municipal for erosion and sediment control tools that match the grading plan, soil conditions, and access limits. Silt fence is used for perimeter control so sheet flow is intercepted before it leaves the disturbed area. Coir logs and straw wattles act as check dams, slowing runoff and capturing sediment where flows concentrate. Compost filter socks are placed where trenching silt fence is not practical, such as tight work zones, utilities, or paved edges, to provide non-trenched sediment capture. On slopes and larger disturbed areas, erosion control blankets protect seeded soil while vegetation establishes, and turf reinforcement mats (TRMs) provide permanent vegetative reinforcement. Together, these measures keep sediment on site and reduce regrading after storms.
• Environmental Restoration: On hillsides and disturbed natural areas, the problem is keeping soil in place and giving new vegetation time to establish within your restoration window, often under a permitted project with SWPPP and Clean Water Act 401 water quality certification conditions. In order to support your enviromental restoration project, Clarion Municipal provides products such as straw, jute, geotextile, and coir blankets, wattles and matting sized to your grading plans so restoration areas stay stable while roots develop. Depending on the schedule and site conditions, straw or coir wattles are placed across the slope to slow runoff and redirect flow. While seed and erosion control blankets made from straw, jute, or coir are then used to hold seed in place while root structures develop. Simple field checks, especially after early storms, help teams spot rilling or undermining below wattles and adjust layouts so the controls continue to support restoration goals and demonstrate that disturbed areas are being stabilized as required.
• Repairing Streambanks & Shorelines: For streams and shorelines, your project is at risk of undercut banks, wake waves, and sediment entering nearby waters. These repair projects are often subject to permits under Clean Water Act Sections 401 and 404, along with oversight from the Environmental Protection Agency (EPA). Municipal crews, engineers, and restoration contractors turn to products like coir logs, blankets, and related controls so they can repair banks, support long-term stability, and stay in compliance with the and regulations surrounding the project. To support the work, we supply coir logs, blankets, various matting and turf reinforcement mats (TRMs). Coir logs are typically installed along this lower zone of the repair project to strengthen the base of the bank, deflect flow, and hold soil while native vegetation establishes along the face. In many restoration plans, coir blankets are used on the upper bank to protect seed and soil, while open-weave mats and TRMs help establish and anchor vegetation in higher-flow areas. As vegetation takes over, the coir, straw, and jute gradually biodegrades, leaving a more natural shoreline that still meets the intent of your restoration documents and permitting requirements.
• Slopes & Embankments: Unprotected slopes and embankments can develop rills and gullies, sending sediment downslope and triggering corrective actions under 40 CFR 450 and local erosion and sediment control ordinances. Clarion Municipal supplies coir logs, straw and coir erosion control mats, and geotextiles to break up flow paths, keep soil in place, and support final stabilization for contractors, municipal crews, and maintenance teams. Starting from your grading plans and slope ratios, crews smooth the slope and create shallow trenches or check locations that slow runoff and spread it out. Coir logs installed in these trenches encourage water to flow over the log while trapping sediment upslope, reducing the risk of rilling and gullying. On more gradual slopes, straw or coir erosion control mats cover the surface, hold seed in place, and prevent water from pooling in low spots. We help you align mat types and wattle spacing with your slope geometry and drainage patterns so disturbed embankments are better protected during storms and less rework is needed before final stabilization.
