Checklist

Install erosion and sediment controls effectively to manage stormwater runoff during earthworks. This checklist focuses on practical erosion control and sediment control measures including silt fence, inlet protection, temporary sediment traps, and access/runoff management. It guides site engineers, foremen, and inspectors through planning, installation, and maintenance without delving into permanent drainage works or landscaping stabilization. By following these steps, teams reduce offsite sedimentation, prevent blocked inlets, minimize rework, and protect nearby waterways and infrastructure. You’ll find measurable tolerances, acceptance criteria, and documentation requirements for defensible records. The checklist complements approved project specifications and authority requirements, giving you a consistent method to prepare for forecast rain events, control discharge from dewatering, and keep access points clean. Use this interactive page to tick items, add comments with photos, and export your record as PDF or Excel with a QR code for quick verification.

Pre-Installation Planning and Layout

1. Review approved drawings to identify catchments, flow paths, sensitive receptors, and control locations; mark on a site plan and verify onsite with walkover.
2. Stake control alignments using stringline and coloured flags; record GPS points at changes in direction; tolerance for placement ±0.1 m from plan.
3. Calculate disturbed area and upslope length to confirm control sizing per approved project specifications; upload calculation sheet and mark-ups.
4. Verify materials onsite: geotextile ratings, silt fence fabric, posts, aggregate sizes, inlet socks; photograph labels and delivery dockets for traceability.
5. Check 72-hour weather forecast; if heavy rain (>20 mm/day) likely, sequence works to install controls first; attach forecast screenshot.

Silt Fence Installation

6. Excavate trench 150 mm deep × 150 mm wide along staked alignment; verify depth with tape measure; photo before placing fabric.
7. Drive posts to ≥600 mm embedment at ≤2.0 m spacing (≤1.0 m on curves); confirm with depth marks; photo each 10 m.
8. Place fabric on upslope side of posts; key-in 150 mm into trench; backfill and compact with hand tamper; no gaps; photo after compaction.
9. Install end returns upslope ≥1.0 m every 10–20 m and at low points to prevent bypass; mark locations on plan and photograph.
10. Where higher velocities are expected, add wire mesh support fence; secure with ties at 300 mm spacing; document supported lengths.

Inlet Protection Installation

11. For curb inlets, install weighted inlet socks 200–300 mm diameter; leave a 50 mm weep gap at the lowest point; photo of gap.
12. For drop inlets, clamp non-woven geotextile under grate; test overflow path remains free; video or photo demonstrating unobstructed bypass.
13. Construct stone ring around drop inlet using 50–100 mm washed aggregate, ~300 mm high, 150 mm offset from grate; photo with scale.
14. Anchor inlet socks/bags with timber stakes at ≤1.0 m spacing; perform tug test to confirm stability; record stake spacing measurements.
15. Position sediment bags on hoses during dewatering near inlets; discharge to stable surface; verify no visible plume extends beyond 5 m; photo.

Sediment Trap Installation

16. Excavate trap per approved drawings; confirm base area and depth with staff and tape; record as-built dimensions and location photo.
17. Form embankment side slopes ≥2H:1V; compact in ≤150 mm lifts; verify with level and compaction passes; photo each lift.
18. Install armored spillway: geotextile underlayment and 100–150 mm rock; set crest level per design; check with laser level ±10 mm.
19. Place outlet rock apron ≥3 m long, ≥200 mm thick using 100–150 mm rock; confirm thickness at three points; photo overview.
20. During excavation, install upstream silt curtain or straw bales to limit turbidity; remove after trap stabilizes; before/after photos.

Runoff and Access Control

21. Construct stabilized construction entrance ≥10 m long, ≥3 m wide with 50–75 mm aggregate over geotextile; thickness ≥150 mm; photo with scale.
22. Install diversion berms/swales upslope to route clean water around work area; gradient 1–2%; verify with spot levels every 10 m; photos.
23. Cover stockpiles or surround with fiber rolls; maintain ≥2 m setback from drains and waterways; photo and location markup.
24. Discharge pumps through sediment filter bag (100–150 μm rating) onto level vegetated area with energy dissipation; verify no scour; photo after 10 min.

Maintenance, Inspection, and Documentation

25. Inspect controls daily during active earthworks and within 24 h after ≥10 mm rainfall; log findings with photos and corrective actions.
26. Remove sediment at silt fence when deposits reach 150 mm depth or 50% height; record removal volumes and disposal location.
27. Repair damaged fabric, posts, inlets, or trap armoring within 24 h; capture before/after photos and supervisor sign-off.
28. Decommission after stabilization (≥70% vegetative cover or surface sealed); remove materials, backfill trenches, grade smooth; final photos and as-built sketch.

Plan Controls Around Flow Paths and Construction Sequencing

Effective erosion and sediment controls begin with mapping catchments, flow routes, and discharge points before earthworks commence. Walk the site to confirm where clean water can be diverted and where dirty water must be detained or filtered. Stake alignments for silt fence and diversion berms using stringline and GPS points so crews install in the right place the first time. Prioritize installing upstream controls ahead of excavation and stockpiling. Check a 72-hour forecast and establish hold points when heavy rain is likely. Verify materials suit the soil and expected velocities—fabric strength, post length, aggregate size, and geotextile type. Record all planning decisions, photos, and mark-ups so the team shares one source of truth and can demonstrate due diligence during inspections.

Stake alignments and record GPS points for traceability.
Install upstream controls before bulk cuts and stockpiles.
Set weather-triggered hold points for high rainfall.
Verify materials match design velocities and soils.

Silt Fence and Inlet Protection That Actually Works

Silt fence must be trenched-in and compacted to stop underflow. Posts should be embedded deep enough and spaced closer on curves to resist loads. Add end returns to prevent bypass and wire mesh where velocities demand extra support. For inlets, use weighted socks with a small weep gap at the low point, and secure drop-inlet protection so emergency overflow stays clear. Stone rings around drop inlets need washed rock and a consistent offset to avoid choking the grate. Always keep fabric on the upslope side of posts and never place silt fence across concentrated flow channels. Take photos that show dimensions, embedment, and free overflows—these are the details inspectors look for.

Key-in fabric 150 mm and compact backfill.
Posts embedded ≥600 mm; tighter spacing on curves.
Maintain a visible weep gap at curb inlets.
Do not obstruct emergency overflow paths.

Build and Maintain Sediment Traps and Runoff Controls

Temporary sediment traps need correct storage volume, stable side slopes, and a well-leveled armored spillway to avoid blowouts. Verify dimensions with a level staff and document as-builts. Install outlet aprons to dissipate energy and avoid scour. Stabilized entrances reduce trackout; combine with diversion swales that keep clean water out of disturbed areas. When pumping, discharge through a filter bag onto a stable surface and confirm no visible plume travels far downstream. Keep a maintenance rhythm: inspect daily during earthworks and after rain, empty controls at 50% capacity, and repair damage within 24 hours. Decommission when surfaces are stabilized and vegetation is established.

Level spillways within ±10 mm to prevent overtopping.
Use 100–150 mm rock for armoring and aprons.
Track inspections and photo evidence after rainfall.
Remove sediment at 50% capacity threshold.

FAQ

Question: When should I choose a silt fence versus a sediment trap?

Use silt fence to intercept sheet flow on gentle slopes and around perimeters or stockpiles. Choose a sediment trap where runoff concentrates, storage volume is needed, or dewatering is expected. Often both are combined: silt fence controls perimeter sheet flow, while traps manage concentrated discharges near outlets.

Question: How do I prepare for forecast heavy rainfall during earthworks?

Install upstream controls first, add returns on silt fence, secure inlet protection with clear overflow paths, and build diversion swales to route clean water around disturbed areas. Pause excavation if necessary, protect stockpiles, and ensure pumps discharge through filter bags to stable ground. Document all steps and the weather forecast screenshot.

Question: What are common causes of control failure and how can I avoid them?

Typical failures include underflow from unkeyed fabric, posts too widely spaced, blocked inlets with no overflow, and unprotected pump discharge causing scour. Avoid them by keying-in fabric, tightening post spacing on curves, leaving weep gaps, armoring spillways and aprons, and verifying installation with photos and measurements.

Question: How often should I inspect and what documentation is required?

Inspect daily during active earthworks and within 24 hours after rainfall of about 10 mm or more. Record findings, photos, measurements, and corrective actions. Keep delivery dockets for materials, as-built dimensions for traps, and sign-offs by responsible personnel. Export periodic reports to PDF/Excel for submission and archiving.
