Published by City of Brampton under Site Alterations
A two-page fact sheet the City of Brampton posts with its site alteration material. It opens with the figure that nearly 1,000 litres of water flows off an average residential roof in a normal rainfall, defines positive drainage, and names the common causes of surface drainage problems: poor lot grading or landscaping, a structure built within a swale, and downspouts or drainage pipes discharging beside a foundation. It points to the lot grading maintenance fact sheet, and describes the city's inspection service and its distance from neighbour disputes.
