A new house built in an older area is called in-fill housing. In these cases, the builders must conform to the provisions of the Property Drainage Bylaw and the Development Standards and Procedures, which prohibits drainage onto adjacent properties. Matching the existing grade at the common property line is normal practice for these developments. Adjacent homeowners must consider their own grading.
They should be aware that under the Property Drainage Bylaw and the Development Standards and Procedures, new homes are required to have a 5% slope away from the foundation walls.
