Construction Site Inspection

A systematic field review of a project's erosion and sediment controls, materials storage, and housekeeping to verify they are installed, functioning, and maintained as required by the applicable stormwater permit.

Related: Inspection Frequency, Inspection Checklist
Inspection Frequency

The required interval between site inspections, set by the governing permit and often adjusted for rainfall events or site risk level. Inspectors must know the minimum schedule and when storm events trigger an additional visit.

Related: Qualified Stormwater Inspector, Rain Event Inspection
Rain Event Inspection

An additional site visit required after a specified amount of precipitation or a qualifying storm. The inspector checks that controls survived the event, that discharges were not turbid, and that repairs are scheduled promptly.

Related: Inspection Frequency, Non-Stormwater Discharge
Inspection Checklist

A standardized form listing each control and condition to verify during a site visit. It ensures consistent coverage, records pass or fail status, and supports the written inspection report.

Related: Inspection Report, Corrective Action
Inspection Report

The written record of a site visit describing weather, areas inspected, deficiencies found, corrective actions required, and the inspector's signature and date. It is a legal document that may be reviewed by regulators.

Related: Inspection Checklist, Corrective Action
Corrective Action

The specific repair, replacement, or installation needed to fix a deficient control, together with a responsible party and deadline. Inspectors document corrective actions and verify completion at a follow-up visit.

Related: Inspection Report, Follow-Up Inspection
Follow-Up Inspection

A return visit to confirm that previously identified deficiencies were corrected within the required timeframe. Findings are recorded and the report is updated to close out each item.

Best Management Practice (BMP)

A schedule of activities, prohibitions, maintenance procedures, or structural controls used to prevent or reduce pollutants in stormwater discharges. BMPs are selected to fit site conditions, soils, slopes, and construction phase.

Related: Erosion Control, Sediment Control
Erosion Control

Practices that keep soil in place and prevent detachment by wind or water, such as mulching, seeding, blankets, and slope protection. Preventing erosion is generally cheaper and more effective than trapping sediment after it moves.

Related: Sediment Control, Best Management Practice (BMP)
Sediment Control

Practices that capture soil particles already suspended in runoff before the water leaves the site, such as silt fence, sediment basins, and fiber rolls. They treat the symptom rather than the source of erosion.

Related: Erosion Control, Silt Fence
Silt Fence

A geotextile barrier installed along a contour downslope of disturbed areas to pond runoff and settle sediment. It must be trenched into the ground, properly staked, and kept free of accumulated soil to function.

Related: Sediment Control, Fiber Roll
Fiber Roll

A cylindrical erosion and sediment control device made of compressed straw, coconut, or wood fiber, staked on contour or at slope toes. It slows runoff, reduces erosion, and traps sediment on mild slopes and around inlets.

Related: Silt Fence, Inlet Protection
Inlet Protection

A temporary barrier placed around a storm drain inlet to keep sediment-laden runoff from entering the drainage system during construction. Common types include gravel bags, filter fabric, and manufactured inserts.

Related: Storm Drain Inlet, Sediment Control
Storm Drain Inlet

The opening where surface runoff enters a municipal or site drainage system. Inspectors check that inlets are protected, unobstructed, and that accumulated sediment is removed before it is flushed downstream.

Related: Inlet Protection, Non-Stormwater Discharge
Sediment Basin

A constructed pond that detains runoff long enough for soil particles to settle before discharge. Inspectors verify capacity, outlet condition, embankment stability, and timely removal of accumulated sediment.

Related: Sediment Control, Dewatering
Dewatering

The removal of groundwater or accumulated water from an excavation or work area. Discharged water must be treated or filtered so it does not carry sediment or pollutants into storm drains or waters of the United States.

Related: Non-Stormwater Discharge, Sediment Basin
Non-Stormwater Discharge

Any flow leaving a site that is not composed entirely of stormwater, such as wash water, concrete slurry, or pumped groundwater. Most such discharges require authorization or treatment before release.

Related: Dewatering, Illicit Discharge
Illicit Discharge

An unauthorized release of non-stormwater into a storm sewer system or waterway, including spills, dumping, and connected sanitary lines. Inspectors look for staining, odors, and unexpected flows at outfalls.

Related: Non-Stormwater Discharge, Outfall
Outfall

The point where a site's drainage discharges to a receiving water or municipal system. Inspectors check outfalls for turbidity, staining, erosion at the discharge point, and evidence of unauthorized flows.
