Lot Grading

Having proper drainage of surface water on your property is important.  The City of Greater Sudbury has a Lot Grading Policy which requires a lot grading plan to be prepared and approved by the City on most properties before development.

 A lot grading plan sets out the intended drainage pattern of a property to help avoid drainage issues that may cause flooding, ponding, water seeping into basements and other issues which can lead to insurance claims and conflict between property owners.

Who Needs a Lot Grading Plan?

Generally, you will need to have a lot grading professional prepare a lot grading plan if you are:

  • building on a vacant lot in an urban or rural area where the lot is 0.4 ha or less and with frontages 50 m or less
  • creating a new lot by severance in urban or rural areas where the lot is 0.4 ha or less and with frontages 50 m or less
  • developing a plan of subdivision
  • building an addition or constructing an in-ground pool

If you are not sure if you require a lot grading plan please contact Development Engineering at 705-674-4455, extension 4295. 

Where development is subject to site plan control  a lot grading plan is one of the plans required as part of that process.
