A group of students enrolled in “Campus as a Living Lab”, a course at Dalhousie University that aims to engage students in efforts to “green” the campus and surrounding areas, have delved into the world of stormwater management. Students, Bridgette DeCoste, Tiara Pettinger, Robyn Pirie, Nicole Power, Michelle Simone and Paul Westlund, chose two areas on campus, the Dunn parking lot and the Grad House, to focus their research. The intention was to create transferable stormwater management designs that could be implemented by homeowners who are interested in managing stormwater on their properties. The students created three levels of increasingly complex designs for both sites and investigated five different management approaches; vegetated swales, permeable pavement, rain gardens, rain barrels, and French drains. The students then presented their designs to experts in the field, as well as with facilities management staff at Dalhousie to determine the most feasible and cost-effective approach to stormwater management on the two sites.
Here are graphics of the third designs for each location

Grad House- featuring french drain, rain barrels and rain gardens
The most interesting part about this report for the Ecology Action Centre is the transferability of the designs. Because each component of their designs is featured individually as well as a part of the whole system, the report contains a wealth of information directly relatable to any homeowner who’s looking into taking on some of these retrofits on their own properties. The report also contains several appendices including tables with a complete breakdown of all the costs associated with these retrofits, and a list of water-loving plants native to Nova Scotia, for installation in the rain gardens.
Thanks to all the students for their excellent work.
