Overview
The City of Brampton's lot grading guidelines on residential surface drainage, written for property owners. It explains how swales, catch basins, eavestroughs, downspouts and window wells carry water off a lot, defines ponding and positive drainage, and gives the 48-hour drying test for normal drainage. It describes what a lot grading plan records, from design elevations to rear lot catch basins, works through common drainage problems between neighbours, and closes with site alteration permits and contacts. It gathers the content of the City's two drainage fact sheets.
