Silt Fence & BMP Installation on an Active Construction Site

Service Area

Central Florida residential development site

Site Condition

A multi-acre residential subdivision in active mass grading, with disturbed soil sloping toward a roadside swale and several storm drain inlets along the site perimeter.

The Challenge

The site needed full perimeter sediment control installed before grading began, sized to handle sheet flow from the disturbed area without overwhelming the downstream swale or inlets.

The Strategy

• • Contour-following silt fence along the full down-slope perimeter
• • Fabric drop-inlet protection at each storm drain inlet along the perimeter road
• • A stabilized construction entrance at the primary vehicle access point

Work Performed

Silt fence was trenched and backfilled along the perimeter, with J-hook returns at low points to prevent end-around bypass. Inlet protection was sized to each structure's drainage area, and a geotextile-based construction entrance was installed at the site's main access point.

Value Created

The site passed its initial SWPPP compliance inspection with no corrective action items, and perimeter controls held through several rain events during the mass grading phase.

Risk If Ignored

Without trenched, contour-following perimeter control in place before grading, sheet flow from the disturbed area would have carried sediment directly into the roadside swale and storm drains — a discharge violation that's expensive to remediate after the fact.

Documentation Delivered

Before/during/after photos of fence trenching, stake spacing, and end returns; inlet protection sizing notes; and a documented walkthrough confirming SWPPP-matching installation ahead of the initial inspection.
