Erosion control is a civil-engineering service in which a licensed Professional Engineer (PE) designs plans to prevent soil erosion and sediment runoff from construction sites. This includes Stormwater Pollution Prevention Plans (SWPPPs), NPDES compliance, sediment barriers, inlet protection, stabilization measures, and temporary and permanent erosion control. Erosion control plans are required for most construction permits and are enforced by local, state, and federal agencies.

What Erosion Control Includes
A licensed civil engineer designs erosion control plans that prevent soil erosion and sediment discharge from construction sites. This includes perimeter sediment barriers (silt fence, brush barriers), inlet protection, temporary and permanent seeding, stabilization measures, diversion swales, sediment basins, and construction sequencing. Every plan is PE-stamped and formatted for local, state, and federal submittal including NPDES stormwater permits.
SWPPP and NPDES Compliance
Construction sites disturbing one acre or more require a Stormwater Pollution Prevention Plan (SWPPP) and NPDES stormwater permit coverage under the Clean Water Act. Our PE prepares SWPPPs that include site descriptions, erosion control measures, inspection schedules, and maintenance requirements. SWPPPs are required before construction can begin and must be maintained throughout the project.
When You Need an Erosion Control Plan
Erosion control plans are required for: any construction site disturbing soil (most building departments require an erosion control plan as part of the permit package), sites one acre or larger (NPDES/SWPPP required), sites near water bodies or sensitive areas (enhanced requirements), hillside or slope construction, and any project where sediment runoff could impact adjacent properties or storm systems.
Residential vs. Commercial Erosion Control
Residential erosion control typically involves silt fence, inlet protection, and temporary seeding for single-lot construction. Commercial erosion control involves larger-scale sediment basins, diversion swales, phased stabilization, and comprehensive SWPPP documentation. Our PE handles both residential and commercial erosion control, sealed and formatted for your jurisdiction's requirements.
erosion control — Definitive Guide
When You Need It
- 01Any construction site disturbing soil (most building departments require it)
- 02Sites disturbing one acre or more (NPDES/SWPPP required)
- 03Sites near water bodies, wetlands, or sensitive areas
- 04Hillside or slope construction
- 05Projects where sediment runoff could reach storm systems or neighbors
- 06Local land-disturbance permit conditions
Engineering Inputs Required
Site drainage patterns and discharge points
Soil type and erodibility characteristics
Disturbed-area boundaries and phasing sequence
Receiving-water proximity and sensitivity
Local and state erosion-control criteria
Typical Deliverables
- PE-stamped erosion-control plan
- SWPPP (where NPDES applies)
- Perimeter, inlet, and slope protection details
- Stabilization and sequencing schedule
- Inspection and maintenance requirements documentation
Common Mistakes
- Installing silt fence as sediment containment rather than intercepting flow — wrong placement fails
- Neglecting inspections required weekly and after rain events under NPDES
- Leaving disturbed areas unstabilized beyond permit deadlines
- Missing inlet protection where runoff enters the storm system
- Starting work before permit coverage, exposing the site to fines
What Determines Cost
- 01Disturbed-area size and construction phasing
- 02Whether a full NPDES/SWPPP package is required
- 03Proximity to water bodies or sensitive areas requiring enhanced measures
- 04Inspection and maintenance commitments, where provided
Engineering fees are project-specific — set by site complexity, jurisdiction requirements, survey needs, and scope. Every project is quoted by a licensed engineer, usually same day. Call (888) 291-6160 for a quote based on your actual project.
Permit Relationship
Erosion control is a condition of most land-disturbance and building permits. NPDES stormwater permit coverage is federally required for sites disturbing one acre or more, with some states regulating smaller sites.

Erosion Control Questions
Do I need a licensed engineer for an erosion control plan?
Most jurisdictions require erosion control plans submitted for permit to be prepared and sealed by a licensed Professional Engineer (PE), especially for NPDES/SWPPP compliance. Call (888) 291-6160 to discuss your project.
What is a SWPPP?
A SWPPP (Stormwater Pollution Prevention Plan) is a document required under the NPDES program for construction sites disturbing one acre or more. It describes erosion control measures, inspection schedules, and maintenance requirements. Our PE prepares SWPPPs for NPDES compliance.
How much does an erosion control plan cost?
Erosion control plans are quoted project-specifically based on disturbed-area size, whether a full NPDES/SWPPP package is required, and site sensitivity. Call (888) 291-6160 for a same-day quote.
When is NPDES compliance required?
Construction sites disturbing one acre or more require NPDES stormwater permit coverage and a SWPPP. Some states require coverage for smaller sites. Local jurisdictions may have additional requirements. Our PE evaluates your project's requirements.
Can you design erosion control for a residential construction project?
Yes. We design erosion control plans for residential construction including silt fence, inlet protection, and temporary stabilization. Most building departments require an erosion control plan as part of the residential permit package.
