Silt Fence & Inlet Protection in Tampa, FL

Silt fence and inlet protection in Tampa are usually the first things on a building site and the last things to come off. The City of Tampa says silt fences must be installed before any earthwork and must stay in place for the whole of construction, and that all inlets should be protected so sediment does not enter the storm system. As silt fence contractors, we install those controls, maintain them through the job, and remove them once the ground is stabilized.

Why the city cares

Tampa's storm system drains to the Hillsborough River, Hillsborough Bay, Old Tampa Bay and the ponds and canals between them. The city treats sediment leaving a site as an illegal discharge, and its inspectors routinely check that erosion and sediment controls are installed and maintained. Failing to do that can bring citations, fines or a stop-work order. A Preliminary Plan Review meeting with Construction Services is part of permitting, and the approved erosion control plan has to be followed on site.

What the city lists

The City of Tampa's list of commonly accepted methods includes a temporary gravel construction entrance, sediment (silt) fence, block and gravel inlet protection, fabric drop inlet protection, street inlet protection, dewatering that discharges only clean water, and floating turbidity barriers. The city also notes that a few small, well-maintained traps or barriers in the right places can control sediment better than a single large basin. That matches what we see: controls fail at the weak spot, not on average.

How a Tampa silt fence should go in

The fabric only filters anything if runoff is forced through it. So the bottom edge is trenched in and backfilled, not laid on top of the sand, and the posts are on the downhill side so the fabric is pressed against them. Fence runs follow the contour where possible, with the ends turned uphill so water does not just flow around them. On Tampa's loose sand, a fence that is only staked at the surface will undercut in the first big storm.

Inlet protection

Curb inlets in the street get filter inserts or barriers that let water through while catching sediment. Yard and drop inlets get fabric or block and gravel protection around the grate. Pinellas County lists inlet protection, silt fencing, turbidity curtains and construction entrances among the practices that must be maintained during construction, and requires perimeter controls before mass grading. Wherever your site is, inlets downstream of bare soil should be protected from the first day.

Maintenance and inspection

Silt fence and inlet filters fill up. Pinellas County requires that controls be inspected at least once a week and after any rain of half an inch or more. In Tampa's rainy season, that can mean several checks a week. We offer scheduled maintenance: removing built-up sediment, re-trenching undercut fence, replacing torn fabric and clearing inlet filters.

Stockpiles, entrances and dewatering

The City of Tampa also asks for a well-planned construction entrance and says construction roads, parking areas and the entrance should be stabilized immediately, with equipment kept to set routes to limit ruts and tracking. Pinellas County requires soil stockpiles to be placed carefully and protected with silt fencing, stabilization or tarps. Where a dig hits groundwater, which is common in the wet season on flatwoods soils, the city says only clean water may be discharged, usually through a dewatering bag or similar filter. We can set silt fence around stockpiles and help you plan where the entrance and spoil piles go so the fence line makes sense.

State permits on larger sites

Florida DEP's Construction Generic Permit applies when a project disturbs one acre or more, and also to smaller disturbances that fall within a larger common development plan, if stormwater leaves the site for state waters or a municipal storm system. Those sites need a stormwater pollution prevention plan, and coverage is closed with a Notice of Termination after final stabilization. Silt fence and inlet protection are usually the core of that plan, and inspectors look for them first.

Removal

Once the site is seeded or sodded and the grass is established, the fence comes out and the trench line is raked smooth and seeded. Taking it out too early is a common mistake; leaving it to rot in place is another.

Common failures we fix

• Fence laid on the surface with no trench, undercut by the first storm
• Fence run straight downhill, so water follows it instead of passing through
• Sediment piled halfway up the fabric and never cleaned out
• Inlet filters left on after paving, blocking the street drain in a downpour
• Gaps at gates and driveways where trucks run over the fence

Most of these are cheap to fix and expensive to ignore, since an inspector who finds sediment in the street is looking at the whole site, not just one bad section. When we take over maintenance on a site someone else set up, we walk the full perimeter first and list what needs fixing.
