Drainage Plan

A Drainage Plan is produced to provide a method of containing rainwater/stormwater runoff. Drainage plans reduce the risk of flooding and water damage to dwellings and help to control the amount of runoff onto neighbouring properties.

The featured plan shows a Post Development Drainage Plan for a proposed subdivision. The property is subcategorized into catchment areas and the topography of the property is assessed to determine which catchment area the runoff water will be contained within. This procedure aids in the determination of proposed new grades on a development property.
