Erosion & Sediment Control Plans

The erosion and sediment control plan may identify the property boundary, limits of disturbance, existing drainage and proposed construction areas. Depending on the assignment, it can show access locations, control measures, stockpile areas and relevant site details. The drawing should relate these items to a clear base plan.

Supporting notes may address the intended sequence, inspection and maintenance responsibilities, repair needs and removal or restoration requirements. Some applications also need a report or calculations. We confirm the requested deliverables rather than assuming that one standard sheet will satisfy every review.

Markham’s published submission outline includes construction sequencing, stockpile information, monitoring, maintenance, contingency planning and record keeping. These topics illustrate why ESC can involve more than placing a fence symbol around a property. However, confirm the project-specific scope with the reviewing authority.

At proposal stage, we identify the included documents, required background drawings and any agreed construction-stage review. The owner should also know who will receive the final documents and who will respond if site conditions differ from the design information.

Erosion control addresses the risk of soil detachment and movement. In contrast, sediment control addresses material that erosion has already mobilized. A coordinated approach considers the disturbed area and the routes by which runoff can carry material toward roads, drainage infrastructure or sensitive features.

The plan should explain the location of each selected measure. Drawing a line around the property is not a substitute for understanding drainage and construction access. The available grading information and sequence of work help frame the design discussion.

For a property owner, useful questions are: Which areas will the work disturb? Where can runoff leave the work area? What needs protection nearby? How will construction vehicles enter? Who will inspect the measures and arrange repairs? These questions help organize the assignment without prescribing a generic design.

The actual choice, layout and detailing of measures should be left to the site-specific design. A list on a website cannot establish the correct spacing, capacity or installation method for your property. Therefore, we avoid standard numerical promises without a review of the relevant criteria and site conditions.

An ESC plan and permission to discharge construction wastewater are different matters. In Toronto, construction wastewater cannot be discharged to the sewer system without the City’s approval. Its guidance describes a discharge permit or agreement route and an alternative involving a licensed waste hauler. Read Toronto’s construction wastewater requirements.

Tell the project team if water is expected to collect in an excavation or if a dewatering arrangement has been proposed. Do not assume that showing a discharge arrow on an ESC drawing authorizes the discharge. The receiving system, approval requirements and relevant specialist input need to be reviewed separately.

At proposal stage, we distinguish the ESC design from any separate dewatering, groundwater or wastewater assignment. If another consultant is responsible for that work, provide their current information for coordination. This helps avoid a gap between the drawings and the permissions needed for the intended arrangement.

Do not use a generic website detail to decide where construction water can be discharged. Follow the authority’s requirements and the approved project documents. If the planned arrangement changes, seek direction through the responsible project team before using a different outlet.

The ESC drawing should use the same current site base as the related engineering plans. Elmid Design Inc. coordinates the information within its scope and identifies where another consultant’s input is needed. The aim is to avoid a set of individually prepared drawings that describe different proposals.

A practical coordination review checks whether the building footprint, access location and work limits match. It also checks whether the grading and servicing designers have received changes to the site layout. Where the construction sequence matters, the team should know which assumptions support the drawing.

Related assignments can include site servicing drawings, a stormwater management report and site plan drawings. Each has its own purpose. Therefore, do not treat an ESC plan as a replacement for permanent drainage or servicing design.

When a layout changes after submission, circulate the revised base drawing with a short change summary. Ask each consultant to confirm which documents need updating. This creates a clearer record than issuing a new drawing without explaining the change to the rest of the team.

A plan is useful only when the responsible site team implements and maintains the specified measures. The construction team needs to know which documents apply, who is responsible for the work and how to report concerns. Those responsibilities should be clear in the project arrangements and approval conditions.

Toronto’s guidance expressly calls for regular inspection and maintenance of erosion and sediment controls. Other jurisdictions and project approvals can set their own requirements. Therefore, confirm the applicable frequency and reporting format for the project rather than copying them from an unrelated job.

Ask who will maintain the inspection record, who will organize repairs and who will communicate a problem to the owner or consultant. An effective handover makes these responsibilities visible before the work begins. It should also identify the current drawing issue so the site team is not working from an obsolete copy.

Elmid Design Inc.’s design fee does not automatically include ongoing construction monitoring or certification. If you need those services, expressly agree on their scope before relying on them. We can review the requested role and information needs, but we do not claim to provide continuous site supervision merely by preparing the drawing.

Start with the municipal address and a plain-language description of the proposed work. Include the property survey, current site plan, architectural drawings and any available grading or servicing information. If you have several drawing versions, identify the latest one.

Send the municipal application checklist or comment letter in full. Include the application number and relevant attachments. Tell us whether the project is at concept stage, under review or already preparing for construction. If work has begun, describe the current stage and any changes to the original plan.

Useful construction information can include the proposed access, work limits and intended staging. If the contractor has not been appointed or the staging is undecided, say so. We can identify the questions that need answers for the drawing rather than fill gaps with unconfirmed assumptions.

You can still enquire if some information is missing. We will review the available material and explain what is needed to define the assignment. Contact Elmid Design Inc. about your ESC plan.

The engineering fee depends on the available information, required deliverables, site complexity and review support. An ESC addition to a coordinated grading assignment is different from a standalone package prepared from incomplete background information. We define the scope before proposing the fee.

Ask whether the proposal includes meetings, responses to comments, additional drawing issues and construction-stage services. Also clarify how the project team will handle changes to the proposed development. A well-defined proposal makes it easier to distinguish the initial assignment from later work requested by the owner or reviewing authority.

The schedule should identify the inputs needed before design can proceed. Survey information, a stable site layout or an application checklist may be important dependencies. Tell us about your target date and the reason for it, so we can discuss the immediate information needs.

However, we do not promise a fixed municipal approval date or guarantee that the authority will issue no further comments. A completed drawing supports the application, but the authority determines whether its requirements have been met. Clear information and coordinated responses help the project team manage the process realistically.

Define the disturbance area for your erosion and sediment control plan. Identify whether the assignment concerns a whole property, a building addition, a servicing corridor or a particular construction stage. If the limits are not settled, explain which parts of the layout are still being developed. The drawing scope should reflect that uncertainty.

The owner can prepare a short brief with the current site plan, proposed activities and known constraints. Ask the contractor or construction manager to identify the access and working arrangements it expects to use. Where that information is not yet available, record it as an input that will need coordination later.

This discussion is different from asking for a generic fence detail. The project team needs to understand the relationship between the work, the site layout and the applicable submission. The designer can then identify the available information and what needs confirmation before issuing the package.

Keep the brief current as decisions change. A plan prepared around one access point may need review if the contractor proposes another. Clear communication of these changes is more reliable than assuming every consultant will notice a different arrangement in a newly circulated drawing.

Elmid Design Inc. prepares site-specific ESC drawings for residential, non-residential and land-development projects in Toronto, the GTA and other Ontario communities. The service-area list below follows our grading service area. Actual requirements depend on the municipality, property and proposal; ask the reviewing authority which drawings and approvals apply.
