So­lu­tions to a sum­mer of floods

Richmond Hill Post - - News -

Thornhill ex­pe­ri­enced heavy rains ex­ceed­ing the cur­rent ex­treme storm man­age­ment in­fra­struc­ture, re­sult­ing in flood­ing in sev­eral ar­eas this sum­mer. These high rain in­ten­si­ties greatly ex­ceeded the ca­pac­ity of the in­fra­struc­ture sys­tems.

Since the Aug. 19, 2005, storm, Markham City Coun­cil ap­proved and im­ple­mented the West Thornhill Stormwa­ter Flood Re­me­di­a­tion plan, a long-term flood con­trol strat­egy, to im­prove storm drainage ca­pac­ity and limit sur­face and base­ment flood­ing risks in ur­ban ar­eas.

The West Thornhill Stormwa­ter Flood Re­me­di­a­tion plan sets out im­prove­ments based on deal­ing with the most se­vere flood risks first. Fur­ther sys­tem up­grades are still planned as part of the long-term flood risk re­duc­tion strat­egy. How­ever, some ar­eas in West Thornhill have not yet re­ceived the ben­e­fit of these im­prove­ment works.

Res­i­dents and busi­nesses are en­cour­aged to help re­duce the risk of flood dam­ages on their prop­erty by keep­ing rain gut­ters and catch basins free of de­bris, dis­con­nect­ing and po­si­tion­ing down­spouts away from foun­da­tions and re­duc­ing pave­ment and other im­per­me­able sur­faces. Plant­ing trees and shrubs helps mit­i­gate storm wa­ter nat­u­rally. Cook­ing oils should al­ways be dis­posed of in the green bin, not down the sink or in the street catch basin.

Fur­ther­more, it is im­por­tant that res­i­dents ad­vise the city of flood in­ci­dents, so staff can con­tinue to re­fine flood re­me­di­a­tion de­sign.
