An investigation into the feasibility of rain gardens as a stormwater management solution Lam, Alfred; Tam, Raymond; Young, Robert; Woo, Sangpil
Abstract
Stormwater pollution is becoming a greater problem in Vancouver with the increase of urbanization. In order to address the problem and to minimize the amount of pollutants discharging into sensitive waterways, UBC is planning to include two rain-gardens in the construction of the new SUB. To analyze the feasibility of rain gardens as a stormwater management solution, a triple bottom line assessment was conducted looking at economic, social, and environmental factors. Based on cost comparisons, case studies and performance reports of rain gardens implemented within the same climate region, academic studies on the social effect of vegetated gardens, and a small student survey, conclusions can be drawn regarding each of the three factors. An economic analysis determined a rain garden would cost less to initiate and to maintain than a regular garden. Socially, the presence of a rain garden could increase student awareness of UBC’s goal in sustainable urban development and raise awareness to an uncommonly known problem of storm-water pollution. Environmentally, a rain garden holds the same benefits as a regular garden in addition to filtering out up to 90% of the chemicals and up to 80% of dissolved solids out of stormwater runoff. Based on these main points, it was concluded that a rain garden is a cost effective method way to filter out stormwater pollutants, add aesthetics, and enhance the natural atmosphere of the university campus.

Stormwater pollution is becoming a greater problem in Vancouver with the increase of
urbanization. In order to address the problem and to minimize the amount of pollutants
discharging into sensitive waterways, UBC is planning to include two rain-gardens in the
construction of the new SUB. To analyze the feasibility of rain gardens as a stormwater
management solution, a triple bottom line assessment was conducted looking at economic,
social, and environmental factors. Based on cost comparisons, case studies and performance
reports of rain gardens implemented within the same climate region, academic studies on the
social effect of vegetated gardens, and a small student survey, conclusions can be drawn
regarding each of the three factors.
An economic analysis determined a rain garden would cost less to initiate and to maintain than
a regular garden. Socially, the presence of a rain garden could increase student awareness of
UBC’s goal in sustainable urban development and raise awareness to an uncommonly known
problem of storm-water pollution. Environmentally, a rain garden holds the same benefits as a
regular garden in addition to filtering out up to 90% of the chemicals and up to 80% of dissolved
solids out of stormwater runoff. Based on these main points, it was concluded that a rain
garden is a cost effective method way to filter out stormwater pollutants, add aesthetics,
and enhance the natural atmosphere of the university campus.
