Site Grading Plans

A site grading plan is a key drawing for permit, severance, minor variance, and site plan applications. It shows how the land will be shaped to direct stormwater runoff, protect adjacent properties, and provide safe access around the site.

At Reliance Engineering Canada Limited, we prepare clear, compliant, and buildable grading plans based on survey data, architectural plans, municipal standards, and site-specific drainage conditions.

We do not just show elevations — we design grading that helps prevent ponding, flooding, drainage complaints, and construction delays.

Why Professional Site Grading Plans Are Essential

Poor grading can cause water to drain toward buildings, create ponding on driveways and walkways, impact neighbouring properties, delay approvals, and lead to costly site rework.
