Understanding Lot Grading Plan Requirements in Ontario

Lot Grading Plans in Ontario are vital in ensuring positive drainage and preventing water accumulation around constructions. Licensed professionals meticulously craft these plans to align with municipal standards. A key focus is storm draining, ensuring the proposed grading doesn’t adversely affect neighboring lots​​.

Key Components

Essential Elements of a Lot Grading Plan

In Ontario, the specifics of a residential lot grading plan are detailed and multifaceted. Here’s a look at some of the critical elements:

Residential Lot Design Specifications

• Topsoil and Sod Requirements: Adequate topsoil depth and quality sod are essential for effective drainage and aesthetic appeal​​.
• Yard and Driveway Slopes: Specific slope percentages are mandated to ensure proper water flow​​.
• Grading Toward Streets: Front yards and driveways must be graded to drain towards the street, preventing water accumulation near the house​​.

Swale Design

Swales play a crucial role in managing surface water. The guidelines for their design include minimum and maximum depths and slopes, ensuring efficient water flow and prevention of flooding​​.

Detailed Requirements for Lot Grading Plans

Lot Grading Plans in Ontario are comprehensive, covering various aspects from site features to service connections. These plans must be meticulously detailed to meet municipal standards and ensure proper drainage and safety.

Site Features and Layout

• Road and Services Layout: Involves detailing curbs, sidewalks, and above-ground services like hydrants and light poles​​.
• Building Elevations: Critical to show proposed elevations for lot corners and building locations, including porches and stairs​​.
• Drainage Directions: The plan must indicate the direction of surface water runoff​​.

Infrastructure and Environment

• Environmental Considerations: Plans should factor in existing trees and propose locations for tree protection zones​​.
• Infrastructure Details: Includes driveway grades, existing spot elevations, and details on proposed retaining walls​​.
• Surface Drainage Indicators: Arrows indicating the direction of surface drainage on all proposed areas are a requirement​​.

• Designer Qualifications: The designer of the Lot Grading Plan must be a certified professional, such as an Ontario Land Surveyor or a Professional Engineer​​.

Review and Approval

• Township Review: The township thoroughly reviews the submitted Lot Grading Plan for approval​​.
• Inspections and Deposits: The process includes inspections, and the return of lot grading deposits is contingent upon passing these inspections​​.

Post-Construction Certification

• Final Certification: After completing the grading as per the approved plan, a final “Lot Grading Certificate” must be issued to certify compliance​​.

Lot Grading Plan Requirements

 Maintaining Existing Drainage Patterns

• We should maintain the existing drainage pattern in the area of the site, also,

• People should not disrupt the natural flow of water in the area.

• The site’s grading should not cause any negative impacts on the surrounding environment.

Draining Side Yards

• It would be best if you drained side yards at surface slopes not less than 1.5%, also,

• should direct the drainage to existing positive drainage outlets.

• should direct existing positive drainage outlets to drain the water.

Swale Slopes 

• Drainage swale longitudinal slopes should not be less than 1.5%, also,
• Terrace and drainage swale side slopes should not exceed 33%.
• Ensure that you efficiently drain excess water away from the property without causing any erosion.

Elevation at Property Line

• The elevation at the property line fronting the street should be such that the average slope down to the top of the roadway curb should be between 2% and 6%, also,
• We ensure to efficiently drain away any excess water from the property without causing erosion.

Rear Yard Slopes

• You should not exceed a 10% slope in the rear yard, except in cases where we are not altering the existing grades, moreover,
• You ensure that excess water is efficiently drained away from the property without causing any erosion.

Siltation Control Methods

• During construction, you should use siltation control methods around the lot perimeter to prevent erosion or siltation on adjacent properties.
• We ensure that we maintain the integrity of the surrounding environment.

Compliance with Ontario Building Code

• We must grade the site to ensure that water does not accumulate at or near the building under construction and does not adversely affect any adjacent properties, also,
• Compliance with Sentence B – 9.14.6.1. of the Ontario Building Code is necessary.

Private Property Catch Basins

• We ensure that we efficiently manage and dispose of any excess water without causing any harm to the environment.

Retaining Drainage on Site

• Whenever feasible, you should retain drainage on site and filter it into the ground for disposal, additionally,
