TOPIC:  Plant Selection for Stormwater Management Facilities

For the past 10 years, the Bureau of Environmental Services (BES) has required the control and treatment of stormwater runoff by way of vegetated stormwater management facilities (SMFs).  SMFs use a combination of soil and plants to detain, treat and infiltrate runoff from roads, roofs and other paved surfaces.  The 2014 Stormwater Management Manual (SWMM) published by BES outlines the function, design and maintenance requirements of SMFs, but does not explain the role of plants in stormwater facilities.  Therefore, designers are left with little to inform their plant selections other than typical landscape considerations which may conflict with the specialized needs of the SMF.

This presentation will outline a framework for the plant selection process for SMFs.  While its basis will be specific to BES facilities built in Portland, Oregon, the intent is to identify specific characteristics of plants rather than the plants themselves, which vary by region.  By identifying important characteristics in plants, designers will be able to focus on the most appropriate plant palette to maximize facility functions.
