Silt Fence & Sediment Control in Charlotte, NC

Silt fence and sediment control are the measures that keep soil from leaving a disturbed site, and in North Carolina they are not optional. We install silt fence, protect storm drain inlets, maintain both through the job and remove them once the ground is stabilized, for builders, site contractors and homeowners around Charlotte. As silt fence contractors who also hydroseed, we look at the whole path from bare dirt to finished grass, not just the fence line.

What the law expects

North Carolina's Sedimentation Pollution Control Act of 1973 governs land-disturbing activity across the state, with exemptions for agriculture, forestry, mining and emergencies. According to NC DEQ, erosion and sedimentation control is required regardless of the size of the disturbance, and the law requires measures sufficient to retain sediment within the boundaries of the site. If the installed measures do not work, additional measures must be added. Sites disturbing more than one acre need an approved erosion and sedimentation control plan, filed at least 30 days before work starts, and local programs can be stricter than the state.

That last point matters around Charlotte, because the metro crosses many jurisdictions. A lot in Mecklenburg County, one in Union County and one across the state line in York County, South Carolina, can each answer to a different office. We work from whatever plan or inspector requirements apply to your site and ask before we assume.

The penalties are real enough that builders take this seriously. DEQ lists civil penalties for each day a site is in violation, and inspectors can issue stop-work orders. Responsibility for keeping the measures working sits with the person financially responsible for the project during construction.

Silt fence, done so it works

Silt fence is a geotextile fabric on stakes, set across the slope below disturbed ground. It works by slowing sheet flow so sediment settles out behind it. It fails in predictable ways, and most of them come down to installation:

• Not trenched in. The lower edge of the fabric needs to sit in a trench that gets backfilled and tamped. If it is just laid on the ground, water runs underneath.
• Run straight downhill. Fence set up and down a slope channels water along it instead of stopping it. It belongs on the contour, with the ends turned uphill.
• Used in a ditch. Silt fence is for sheet flow. In a channel with concentrated flow it gets undercut or knocked flat.
• Never cleaned out. Once sediment builds up behind the fence, it stops holding anything. It needs to be cleaned out and repaired after storms.

On steep or high-flow sections, a stabilized silt fence with wire backing or tighter post spacing holds better than standard fabric. We will recommend it where it is needed and not where it is not.

Inlet protection

Storm drain inlets near a site are where sediment escapes fastest. DEQ notes that sediment can clog storm drains and increase the potential for flooding. Inlet protection traps it at the grate: silt fence barriers, sandbags, gravel and mesh, or inserts sized to the structure. These need regular cleaning, and DEQ's storm guidance notes that inlet inserts may need to come out temporarily before a major storm so streets do not flood, then go back in once it passes. We install, maintain and swap them as the job requires.

Weather keeps us busy

Charlotte's rain is spread across the year, with more than 112 days of measurable precipitation on average, and summer storms come hard and fast. A silt fence line that was fine in April can be overloaded after one August cloudburst. We offer inspection and repair visits after significant rain, and we can combine them with seeding or blanket work as areas reach final grade. When the site is stabilized and the inspector signs off, we pull the fence and stakes, spread the trapped sediment and seed the disturbed strip. Get a free estimate

Construction entrances

Much of the mud on Charlotte streets near construction does not come over a silt fence; it rides out on tires. A stabilized construction entrance, a pad of stone at the point where trucks leave the site, knocks off much of that soil before it reaches the pavement. Many approved plans call for one. We can work it into the same visit as the fence and inlet protection, and we will price it after seeing where traffic actually enters and how long the pad needs to be.

Homeowner projects

You do not need to be a developer to need sediment control. Additions, pools, regrades and tear-downs on small lots all disturb soil, and the state rule applies regardless of size. A short run of silt fence along the low side of the lot and protection on the nearest street inlet is often enough to keep mud off your neighbor's driveway and out of the drain.
