Erosion and Sediment Control Plan

Erosion and Sediment Control Plan Services

Construction work can disturb soil and increase the risk of erosion, sediment movement, and muddy runoff. A clear erosion and sediment control plan helps manage these risks throughout construction.

Elmid Design Inc. prepares practical erosion and sediment control plans for residential, commercial, and land development projects across Toronto and the GTA. We review the proposed work, site conditions, drainage patterns, and municipal requirements before selecting suitable control measures.

When May You Need an ESC Plan?

A municipality or reviewing authority may request an erosion and sediment control plan when a project involves soil disturbance, excavation, grading, or changes to existing drainage.

An ESC plan may be needed for:

• New building construction
• Residential additions
• Site grading work
• Land development projects
• Road and utility construction
• Excavation and foundation work
• Site alteration applications
• Projects located near watercourses or sensitive areas

Requirements vary by project and municipality. Therefore, the plan should reflect the actual site conditions and proposed construction work.

What Does an ESC Plan Include?

An erosion and sediment control plan shows how soil, sediment, and construction runoff will be managed on the property. Depending on the project, the plan may include:

• Existing and proposed site conditions
• Property boundaries and construction limits
• Existing drainage patterns
• Areas of soil disturbance
• Construction access locations
• Sediment control barriers
• Storm drain inlet protection
• Stabilized construction entrances
• Stockpile protection
• Temporary drainage measures
• Inspection and maintenance notes
• Removal and restoration requirements

The selected measures depend on the site layout, slopes, soil conditions, drainage system, and construction activities.

Common Erosion and Sediment Control Measures

Different sites require different control methods. Common measures include silt fencing, sediment traps, mud mats, inlet protection, and stabilized construction entrances.

Stockpiled soil may also need covers or perimeter controls. In addition, disturbed areas may require temporary stabilization to reduce soil movement during rain or strong winds.

The contractor must install and maintain the selected measures during construction. Damaged or ineffective controls should be repaired when necessary.

Our Design Process

First, we review the available survey, drawings, and proposed scope of work. Next, we examine the site grading, drainage direction, construction access, and nearby sensitive features.

We then prepare an erosion and sediment control plan that coordinates with the proposed site design. When required, we can also revise the plan in response to municipal review comments.

Our goal is to provide a clear drawing that the contractor can understand and use during construction.

Information We May Need

To begin the design, we may request:

• A current property survey
• Architectural or site plan drawings
• Existing and proposed grading information
• Municipal comments or application requirements
• Details about the proposed construction
• Available servicing and drainage drawings
• A construction access plan

The exact information depends on the size and complexity of the project.

Erosion and Sediment Control Plans Across Toronto and the GTA

Elmid Design Inc. provides erosion and sediment control planning for projects across Toronto and surrounding GTA municipalities.

Because municipal requirements can vary, we review the applicable design criteria before preparing the plan. This helps ensure that the drawing is suitable for the project and its approval application.

Related Engineering Services

An erosion and sediment control plan may be coordinated with other civil engineering documents. Our related services include:

• Site Grading Plans
• Site Servicing Plans
• Stormwater Management Reports
• Functional Servicing Reports
• Site Plan Approval drawings
• Building Permit drawings

Coordinating these documents can reduce conflicts between grading, drainage, servicing, and construction controls.

Frequently Asked Questions

What is an erosion and sediment control plan?

It is a drawing that identifies measures used to reduce soil erosion and prevent sediment from leaving a construction site.

When is an ESC plan required?

It may be required when construction involves excavation, grading, soil disturbance, site alteration, or work near sensitive drainage features. The municipality determines the exact requirements.

What measures can be shown on the plan?

The plan may show silt fencing, stabilized entrances, inlet protection, sediment traps, stockpile controls, temporary drainage measures, and site restoration notes.

Who maintains the control measures?

The contractor or site operator normally installs, inspects, and maintains the measures during construction.

Can the ESC plan be combined with a grading plan?

In some projects, erosion and sediment control information can be included on the grading plan. However, larger or more complex projects may require a separate drawing.
