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?

- 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
