Raingarden planting cross section: AutoCAD.
Raingarden plan: AutoCAD.
Site: Burlington, Ontario. GO Commuter train station, renovation of existing station and landscape. The existing landscape was primarily small areas of grass with minimal shade trees. Little permeability on the site, leading to a high rate of runoff.
Program: A high performance landscape with minimal maintenance requirements. Reduced runoff with on site catchment areas, native hardy low maintenance plantings, high albedo paving, permeable paving, achievement of LEED certification.
Process: Site analysis to determine opportunities and constraints from the existing site. Adherance to the Metrolinx design manual. (Metrolinx operates all commuter rail in the Toronto area, with approximately 63 stations.) Coordination with architecture, engineering, and Metrolinx officials. Research and studies of bio-swale/raingarden performance as this was a groundbreaking project for Metrolinx and would contain the first best managment practices for any new project.
