Silt Fence & Inlet Protection in Dallas, TX

Silt fence and inlet protection keep sediment from a Dallas construction site out of streets, storm drains and creeks. Silt fence is a woven geotextile trenched into the ground on stakes, set downhill of disturbed soil so runoff slows and drops its load. Inlet protection surrounds or covers storm drain inlets so muddy water does not go straight into the system. We install both for home builders, commercial contractors, utility crews and homeowners doing large additions, and we tie the work to seeding so the controls can come out once the ground is stable.

When the rules apply

The TCEQ Construction General Permit, TXR150000, covers construction that disturbs one acre or more and discharges stormwater to surface water in the state. Small sites of 1 to under 5 acres and large sites of 5 acres or more both need a stormwater pollution prevention plan, which TCEQ describes as a document that outlines construction plans and the best management practices used to control pollutants in runoff. Work that disturbs under an acre and does not belong to a larger common plan of development does not need permit coverage. A single lot inside a new subdivision is a different story, because the whole development's acreage counts.

Why clay sites need it

Blackland clay particles are fine and stay suspended in runoff, which is why water leaving a bare Dallas site turns the color of chocolate milk. A storm can carry a surprising amount of that soil into the street in one afternoon, especially in May and October, the wettest months here. Silt fence does not filter clay so much as pond the water behind it and let it settle, so it has to be installed correctly: trenched in, backfilled, staked on the downhill side and set across the slope, not up and down it.

Installing it right

Most silt fence failures we see come from three things: fabric laid on the surface instead of trenched, fence run straight downhill so water just follows it, and no maintenance after the first storm. We trench the toe, compact the backfill, turn the ends uphill so water cannot slip around, and space stakes for the soil and flow. On long slopes we break the run up with additional rows instead of asking one line to hold everything. Where a site plan calls for wire-backed or stabilized fence, we build to that detail.

Inlet protection options

Curb and area inlets near active lots are the last chance to catch sediment before it leaves the site. What we set at each one depends on the kind of inlet and how much traffic passes it: silt fence barriers, sandbags, gravel and mesh, or devices that sit below the grate. Inlets in streets that carry traffic need protection that will not create a hazard or flood the road, so we look at each one before choosing.

Maintenance and removal

Sediment control only works while it is maintained. After significant rain, fence fabric sags, stakes lean and sediment builds up behind the line. We offer inspections and repairs after storms, clean out built-up sediment, and replace damaged sections. Once the seeded areas have taken hold and the site operator is ready to close out, we pull the fence and stakes, rake out the trench and seed the disturbed strip so it does not become the next bare spot.

Sediment control on small and infill lots

Infill and teardown-rebuild projects in established Dallas neighborhoods are often well under an acre, but they sit right next to streets, alleys and storm inlets, and neighbors notice mud in the gutter. Even where the TCEQ permit does not apply, a short run of silt fence along the low side of the lot and protection on the nearest inlet keep a site cleaner and make it easier to deal with city inspectors and neighbors. On these tight sites the fence often has to work around driveways, dumpsters, material drops and a stabilized entrance, so we lay it out with the builder to leave access where trucks need it. We also look at where water leaves the lot during a storm, because on flat Dallas ground runoff often follows the street gutter or an alley rather than the slope you would expect. Once the house is framed and landscaping begins, the fence can come down in sections as the yard is graded and seeded, so the lot moves from bare dirt to finished lawn without a gap where sediment can escape.

Pricing

There is no current consumer price guide for silt fence, so the table borrows its rates from a road agency's 2025 unit rates. Treat them as a sense of scale; actual cost depends on length, access, soil, the plan's detail and how often maintenance is needed. If your inspector asks for changes to fence lines or inlet controls partway through the job, call us and we will adjust them; the plan is meant to change as the site does.
