TECHNICAL / COORDINATION

Site Grading & Drainage Plan Coordination

828 Design coordinates site grading and drainage information with building permit drawings where the project requires a grading plan, while independent engineers or Ontario Land Surveyors remain responsible for engineered or surveyed grading work where required.

This is a coordination service—not a claim that 828 Design provides civil engineering, legal surveying or grading certification.

DIRECT ANSWER

What does this service need to solve?

A grading plan shows how proposed construction relates to site elevations, drainage direction and adjacent property conditions. The municipality may require the grading information to be prepared or certified by a specific regulated professional.

Technical permit information must match the project and the professional responsibility being accepted. 828 Design coordinates building-design documentation within applicable scope and identifies when independent regulated professionals are required.

PROJECT REVIEW

What changes the scope of Site Grading & Drainage Plan Coordination?

The same project name can require different drawings and approvals on different properties. These four checks help define the real permit problem before the set is developed too far.

01

Accepted responsibility

The service must match the applicable BCIN qualification or the independent professional taking responsibility.

02

Existing information

Reliable measurements, base drawings, equipment data or consultant information may be needed before coordination.

03

Cross-discipline impact

Structural, mechanical, plumbing, electrical and architectural information can affect one another.

04

Permit integration

Technical sheets need to coordinate with the main permit set instead of being prepared as disconnected documents.

PERMIT DOCUMENTATION

What the project package may need to communicate

The exact documents depend on the property, building, proposed work, municipality and professional scope. A coordinated set should explain the work clearly enough for the applicable review.

Base drawings

Use coordinated architectural or measured information as the reference for technical work.

Technical layouts

Show equipment, systems, structural elements or permit information relevant to the accepted scope.

Schedules & notes

Provide project-specific data and notes required to explain the coordinated permit design.

Sections & details

Use sections or details where plan views alone cannot communicate the condition.

Consultant information

Integrate independent professional input where the project legally requires it.

Permit-set coordination

Check that technical information aligns with the building permit drawings and current project revision.

SERVICE DETAILS

Grading and drainage information must use the right professional source and match the building set

What grading information can communicate

Depending on the municipality and project, grading information can show existing and proposed elevations, slopes, drainage direction, swales, retaining conditions, entrances, building elevations and relationships to neighbouring grades or municipal infrastructure.

Engineer or surveyor responsibility may be mandatory

Some municipalities require grading plans for development or site-plan control to be prepared, signed or certified by a Professional Engineer or Ontario Land Surveyor. 828 Design does not replace that regulated responsibility. Where required, we coordinate the independent professional’s information with the building plans.

Why building and grading drawings need to match

Foundation elevations, entrances, walkouts, steps, decks, garages and additions depend on exterior grades. A change to the building can change the grading problem, and a grading constraint can change the building design. Using coordinated revisions helps prevent inconsistent permit documents.

OUR PROCESS

How the permit drawing service moves forward

A clear sequence helps separate feasibility, design, documentation and municipal review without implying that any approval result is guaranteed.

01

Property / Project Review

Review the address, proposed work or use, available drawings and the main zoning/permit questions.

02

Existing Information

Confirm the measurements, survey/base-building information, photographs or consultant inputs needed for the accepted scope.

03

Permit Documentation

Prepare and coordinate the drawings and supporting information included in the written service agreement.

04

Submission / Review

Support the agreed municipal submission or comments process; added revisions and new requirements are handled as separate scope where applicable.

STARTING INFORMATION

What to send for a project review or quote

Good starting information helps identify the correct service and avoids guessing about the building or property.

  • property or project address and municipality
  • short description of the proposed work or use
  • survey, existing drawings or landlord/base-building plans if available
  • photos of existing conditions
  • municipal comments, orders or prior permit information if applicable
AFTER APPROVAL

The issued permit is the construction reference.

Contractors and owners remain responsible for construction, site safety, inspections and building in accordance with the issued permit documents. Material field changes should be reviewed before they are constructed because revised drawings, engineering or municipal approval may be required.

COMMON QUESTIONS

Site Grading & Drainage Plan Coordination questions

Short answers first, with project-specific limits stated clearly.

Is a grading plan the same as a site plan?

No. A site plan primarily shows property/building relationships and site features; a grading plan focuses on elevations, slopes and drainage. A project may require both.

Can 828 Design stamp an engineered grading plan?

No. Where a municipality requires a Professional Engineer or Ontario Land Surveyor to prepare or certify the grading plan, that independent professional must take responsibility.

When can grading affect a basement walkout or addition?

Exterior entrances, foundations, stairs, retaining conditions and additions can change site elevations and drainage. The building and grading information should be coordinated.

Can the municipality require a grading deposit or separate agreement?

Some municipalities have separate grading, site alteration or engineering processes. Those requirements are municipality-specific and are not included automatically in a building-design service.

What information should I send?

Send the property address, survey/site plan, proposed building work, existing grades or municipal grading information if available and any engineering or municipal comments.

What information is needed before technical coordination starts?

The required inputs depend on the service but can include architectural base drawings, site measurements, equipment information, existing system data and the current permit scope.

Is professional engineering included automatically?

No. Where Ontario law or the project requires a Professional Engineer, engineer, surveyor or other regulated professional, that professional remains separately responsible for their work.

Why do technical drawings need to match the architectural permit set?

Openings, room uses, dimensions, equipment, loads and service routes interact. Coordinating the current drawings helps reduce contradictory information across the permit package.
