bioswales for subdivisions (Ottawa)
While researching "urban streams" awhile back, I came across this information on bioswales (in Seattle): Urban Ecology's What is a Bioswale? I've heard alot about them for cities that have high annual rainfalls like Portland and Seattle. Bioswales are great as they provide a green buffer that act as a natural storm water collector and rain water filter.
And then just this week, I came across this application from Tartan Land Corporation in Ottawa for a bioswale/hedgerow: From the Lashley + Associates website:
BIOSWALE CASE STUDY FOR SUBDIVISION APPLICATIONS OTTAWA, ON
"Tartan Land Corporation engaged Lashley + Associates, in collaboration with IBI Group to address issues regarding the provision of a “living fence” rear yard planting scheme of native woodlot / hedgerows in conjunction with rear yard drainage systems for Tartan’s subdivision developments.
Our firm developed a new “living fence” / drainage system detail called a Bio-retention Cell System based on existing research, case studies and successful installations in other locales. The bio-retention cell and the living fence have been combined to meet the goals for the subdivision rear yard design and address the City’s issues."
Lashley + Associates also did the amazing xeriscape courtyard design that I featured earlier in this blog for Environment Canada: D + C: More Xeriscaping!
