SITING AND GRADING PLAN
RESIDENTIAL INFILL GRADING AND SERVICING (RIGS) - CITY OF MARKHAM
In Compliance with Sentence B-9.14.6.1 of the Ontario Building Code, every lot in the City of Markham is to be graded so that stormwater will not accumulate at or near the building under construction and will not adversely affect any adjacent lots. The lot grading criteria has been primarily developed to provide guidance to residential development in subdivisions in the City of Markham. The basic principles do however apply to lots under site plan development in the City of Markham..
It should be noted that the lot grading design for any residential buildings containing three or more dwelling units and for any development other than residential, shall be performed by a licensed professional engineer in the City of Markham.
Our licensed professional engineers prepare stamped engineering Siting and Grading Plan, Residential Infill Grading and Servicing (RIGS) Plan, and Lot Grading Plan that would fulfill all engineering requirements for site plan approval and building permits by the City of Markham. Having vast experience in municipal engineering design, we offer effective, innovative and cost-efficient stamped engineering Siting and Grading Plan, Residential Infill Grading and Servicing (RIGS) Plan, and Lot Grading Plan to our clients in the City of Markham.
Our licensed professional engineers’ proficiency in conceptualizing Siting and Grading Plan, Residential Infill Grading and Servicing (RIGS) Plan, or Lot Grading in accordance with our clients' requirements has made us very successful. Our licensed professional engineers prepare thorough, detailed, and clear Siting and Grading Plan, Residential Infill Grading and Servicing (RIGS) Plan, or Lot Grading Plan to suit our client's needs while also adhering to engineering design requirements of the City of Markham and submit to the City of Markham for review and approval to obtain site plan approvals and building permits.
Siting and Grading Plan, Residential Infill Grading and Servicing (RIGS) Plan, and Lot Grading Plan incorporating Erosion & Sediment/Siltation Control Plan, as per applicable the City of Markham guidelines/requirements prepared and stamped by our Licensed Professional Engineers would be ready in 5 business days upon receipt of all the required information and documents. It is important to note that many assumptions, methodologies require varying degrees of engineering judgement that may, or may not, be easily adopted by the reviewing public agencies through their critical review of our reports, plans and drawings. No additional charges for required revisions & changes to our drawings and plans due to the comments from the City of Markham upon reviewing the drawings prepared by us.
Following supporting documents may be required to prepare the Siting and Grading Plan, Residential Infill Grading and Servicing (RIGS) Plan, and Lot Grading Plan for approval by the City of Markham.

•If municipal services are not available, location of well(s) and septic system(s) with offsets from the proposed development.
•If applicable, locations of any regulatory flood lines or development limit lines (i.e. setback and slope stability limits from the Toronto Region Conservation Authority- TRCA).
Where there is a landscape plan proposed as part of the site plan application to the City of Markham, the professional engineer designing the Siting and Grading Plan, Residential Infill Grading and Servicing (RIGS) Plan, or Lot Grading Plan shall review the landscape plan and shall provide the City of Markham with a declaration advising that the proposed landscape works are in conformance with the Siting and Grading Plan, Residential Infill Grading and Servicing (RIGS) Plan, or Lot Grading Plan. Once construction is completed, the professional engineer designing the Siting and Grading Plan, Residential Infill Grading and Servicing (RIGS) Plan, or Lot Grading Plan shall provide the City of Markham with a Final Lot Grading Certificate and any required Retaining Wall Certificates.

Abandoned service connection shall be grouted. Video evidence of abandonment shall be provided to the City of Markham. Storm manholes shall be abandoned by removing the top 1.0m of the manhole and filling the remaining manhole with sand. For manholes under the City of Markham's right of way, U-fill shall be used to fill the manhole.
REUSE OF EXISTING SERVICE CONNECTIONS FOR INFILL RESIDENTIAL DEVELOPMENTS
For infill residential redevelopment, existing service connections can only be reused if the owner/proponent satisfies and complies with the following requirements:
Reuse Existing Water Service Connections
a)Comply with the City of Markham’s latest design criteria.
b)Provide calculation from a licensed professional engineer, based on the proposed house fixture unit water demand to demonstrate that the existing water service connection can provide adequate supply and pressure to the development in accordance with the Ontario Building Code requirements.
c)Verify with the City of Markham’s existing hydraulic characteristic at the site to ensure any existing hydraulic issue(s) will be addressed in the servicing design. Any non-compliant existing water service connections must be disconnected and abandoned in accordance to the City of Markham’s Design Criteria and new water service connections install for the developments. For the road restoration requirements of the construction trenches, follow the “Backfill and Road Restoration Details” of the “Municipal Inspection and Construction Guidelines”.
Reuse of Existing Sanitary Service Connections
a) Comply with the City of Markham’s latest Design Criteria and meet all current City of Markham's Standards and Specifications. The existing municipal sanitary sewer connection shall be free of any structural or operational defects as determined by and at the sole discretion of City of Markham's Director of Engineering and shall have no record of any sewer backups or any other recorded operational deficiencies.
b) Before demolishing the existing building, the owner/proponent shall perform a CCTV inspection from the cleanout inside the building to determine whether the condition of the existing service lateral within the City of Markham’s Right-of-Way is acceptable for reuse.
c) Verify by a licensed professional engineer (P. Eng.) and indicate on the Engineering Drawings that the existing sanitary service lateral elevation at the property line can service the proposed basement by gravity. The Engineering Drawings must show the elevation of both the existing sanitary service lateral at property line and the underside of the footing verified by an Ontario Land Surveyor (OLS).
d) If the designed basement elevation is too low to be serviced by gravity from the building to the mainline sanitary sewer, the following design options shall be considered:
i) Pump the main floor and basement using a grinder pump, to the sanitary service lateral (provided the existing sanitary service lateral satisfies a, b, and c above).
ii)Drain the main floor by gravity to the sanitary service lateral (provided the existing sanitary service lateral satisfies a, b,and c above) and pump the basement by a grinder pump. Note that pumping via grinder pump is only permitted where a gravity outlet to the main sewer cannot be achieved.
Reuse of Storm Sewer Service Connections:
a) Comply with the City of Markham’s latest Design Criteria and meet all current City of Markham’s Standards and Specifications. The existing municipal storm sewer connection shall be free of any structural or operational defects as determined by and at the sole discretion of the City of Markham's Director of Engineering and shall have no record of any sewer backups or any other recorded operational deficiencies.
b) Before demolishing the existing building, the owner/proponent shall perform a CCTV inspection from the cleanout inside the building to determine whether the condition of the existing service lateral within the City of Markham’s Right-of-Way is acceptable for reuse.
c) Verify by a licensed professional engineer (P. Eng.) and indicate on the Engineering Drawings that the existing storm service lateral elevation at the property line can service the proposed basement by gravity. The Engineering Drawings must show the elevation of both the existing storm service lateral at property line and the underside of the footing verified by an Ontario Land Surveyor (OLS).
d) If the designed basement elevation is too low to be serviced by gravity from the building to the mainline storm sewer, a sump pump is required to be installed in the basement to drain the foundation drain to the existing storm service lateral (provided the existing storm service lateral satisfies a, b,and c above).
