Erosion Control & Silt Fencing Installation
in Wilmington, NC
Wilmington Elite Grading & Excavation has been installing erosion control measures for Wilmington-area builders and property owners for over 20 years! Silt fence installation typically costs $3 to $8 per linear foot, and the Clean Water Act's NPDES program requires any construction site disturbing one acre or more of soil to implement erosion control measures, with non-compliance penalties reaching tens of thousands of dollars per violation. Wilmington's sandy coastal soil erodes quickly without groundcover in place, and a wet season that delivers nearly 40% of the year's rainfall between July and September makes erosion control especially important on any actively graded site here.
A silt fence or erosion control plan isn't just a compliance formality, since a failed or missing installation can trigger a stop-work order that costs far more in delay than the erosion control measures themselves. Wilmington Elite Grading & Excavation installs and maintains erosion control systems that meet local and federal stormwater requirements on active construction sites throughout the greater Wilmington region.
Why Choose Us
Local Land Grading
& Excavation Contractors
Wilmington Elite Grading & Excavation has completed grading and excavation work on more than 1,800 residential and commercial lots across the greater Wilmington region. Our crews understand New Hanover County's flood zone maps, Cape Fear River floodplain restrictions, and the sandy, well-drained soil common to coastal Southeastern North Carolina construction.
Advanced Grading Techniques
Our operators are trained on laser-guided grading systems, GPS machine control, and compaction testing equipment that verifies soil density meets 95% Proctor compaction standards before foundation work begins. Equipment operators complete manufacturer safety certification and OSHA 10-hour construction safety training.
Proven Track Record
More than 92% of customers who complete a project with us report they would use our services again for future site work, based on internal post-project surveys. Our completed project mix spans new home construction, commercial pad sites, septic system installs, drainage correction, pond excavation, and storm-damage debris removal following tropical storm activity.

Erosion Control & Silt Fencing Installation We Provide
Silt Fence Installation
We install silt fence with posts spaced 6 to 10 feet apart and embedded 12 to 18 inches deep per EPA stormwater guidance and state erosion control standards. Silt fence installation typically costs $3 to $8 per linear foot depending on fabric quality, site terrain, and soil conditions. This service is required on nearly every permitted construction site disturbing an acre or more of soil.
Inlet and Outlet Protection
We install inlet and outlet protection devices to prevent sediment from entering storm drains and discharge points during active construction. Inlet protection barriers are a required component of most approved erosion control plans and are inspected alongside silt fencing. This service protects downstream water quality and keeps a site in compliance during grading and excavation work.
Temporary Seeding and Groundcover
We apply temporary seeding and groundcover to stabilize disturbed soil that will remain exposed for an extended period during a project. Bare, disturbed soil erodes significantly faster than vegetated ground, particularly on Wilmington's sandy coastal soil during heavy rain events. This service reduces sediment runoff between the time soil is disturbed and final landscaping is installed.
Erosion Control Plan Compliance and Maintenance
We inspect and maintain erosion control measures throughout the life of a project, since silt fence and inlet protection require regular upkeep to remain effective after storms. A damaged or clogged silt fence that isn't repaired promptly can fail exactly when it's needed most during heavy rain. This service keeps a site in ongoing compliance rather than just passing an initial inspection.
Erosion Control Plan Design and Permitting Support
We help design erosion control layouts that meet the requirements of a site's approved stormwater permit, positioning silt fence, inlet protection, and groundcover to match the site's grading plan. Getting the erosion control plan right before construction begins helps avoid the cost and delay of a failed inspection or required rework. This service applies to both residential subdivisions and commercial development sites.
Types of Properties We Serve
New Construction and Builder Sites
Builders need erosion control installed and maintained for the duration of active construction to stay in compliance with permit requirements. We coordinate installation timing with site clearing and grading so erosion control is in place before soil disturbance begins.
Commercial Development Sites
Commercial developments disturbing significant acreage require an approved erosion control plan as part of their stormwater permit, often with more extensive inlet protection and sediment basin requirements. We work with civil engineers to implement erosion control that matches the approved site plan.
Subdivision and Multi-Lot Developments
Subdivision developments need erosion control coordinated across multiple lots and phases of construction simultaneously. We scale erosion control installation and maintenance to match the pace of lot development across a subdivision.
Some of Our Customer Reviews
"Our site inspector flagged an issue with our old silt fence and they had it repaired the same day. Kept our project moving without a stop-work order."
— Builder client, Wilmington, NC
"They installed erosion control ahead of our subdivision phase in Leland exactly to the approved plan. No issues with inspections."
— Developer client, Leland, NC

Erosion Control & Silt Fencing FAQs
How much does silt fence installation cost?
Silt fence installation typically costs $3 to $8 per linear foot depending on fabric quality, site terrain, and project length, with most contractors carrying a minimum job fee of $500 or more.
Do I need erosion control for my construction project?
Any site disturbing one acre or more of soil is required to implement erosion control measures under federal NPDES stormwater regulations, and some local jurisdictions require it for smaller sites as well.
What happens if erosion control fails or isn't maintained?
A failed or unmaintained erosion control system can result in a stop-work order, stormwater violation, and required rework, which typically costs significantly more than ongoing maintenance would have.
Do you handle ongoing maintenance after installation?
Yes, we inspect and repair silt fence and other erosion control measures throughout the life of a project, particularly after significant rain events.
How long does silt fence installation take?
Most residential and small commercial silt fence installations take one day, while larger or more complex sites can take several days depending on total length and terrain.
